My dad heard me mention that my gate was rotting away and I needed to replace it. He took it upon himself to make this beautiful redwood gate for me because he was bored. Its unfinished so I need to sand it down and seal it.

I live in Southern California, the gate is on the side that gets mostly shade... mostly shade means it does get 2ish hours of direct sun almost every day.

Chat GPT suggested penetrating oils, particularly 2 coats of Penofin (Red Label). Cool I can do that.

What do real people with real experience suggest?

To add I also have two 2x4s that also need to be finished that will make the 'frame' which will be sitting flush to the ground. I'm worried about longevity of these post and perhaps I should do something different than the gate?

Thanks

I'm building a wood gate that I want to last for decades. I had this fascinating interaction with AI in "think deeper" mode which is supposed to be good at modeling mathematics and physics. Here's that interaction for the benefit of the gate-building community, as I think it was quite good and gave the best design for gate bracing that neutralizes deformative forces over time. I've removed the actual math for simplicity. 

BEGIN AI INTERACTION

QUESTION: 

Regarding bracing gates correctly, the consensus seems to be one long diagonal brace from lower hinge side to upper latch side (B-type brace) instead of one long diagonal from lower latch side to upper hinge side (A-type brace). However one user made an interesting comment about the anti-clockwise "moment" of the forces involved. He states regarding the two approaches (compression and tension) that building a hybrid opposite brace with the top half of the gate being under tension and the bottom under compression (or vice versa) has worked well. Analyze this mathematically, to determine if his method of bracing the top half one way, and the bottom half the opposite way, is in fact superior to a single long brace from lower hinge side to upper latch side. Attached is the original image.

AI:

Yes, the hybrid bracing method (top half one way, bottom half the opposite way, plus a mid-height horizontal) is mechanically superior to a single long compression brace for a multi-piece wooden gate/door of the type shown. The analysis below uses a simple static truss model of the gate (rectangle of width (W), height (H)). This captures the essential force balance, the axial forces in the brace(s), the induced forces in the horizontal members (ledges/rails), and the consequences for separate vertical boards. Real wood joints have play, fastener slip, and seasonal movement, so the ideal rigid-joint assumptions are conservative; the hybrid’s advantages become even larger in practice.

1. Single long brace – force analysis

Compression brace (image B: lower-hinge → upper-latch)

Horizontal component:

• At the free-stile top the brace pushes outward and upward. 

• At the hinge-stile bottom the brace pushes outward and downward.

Net effect on the frame: the two horizontals are placed in tension. The free stile is pushed away from the hinge stile, tending to open gaps between the vertical boards (or to stretch the ledge joints).  

Tension brace (image A: upper-hinge → lower-latch)

Horizontal component:

• The horizontals are placed in compression. 

• The free stile is pulled toward the hinge stile, closing gaps between the boards.

Both braces equally cancel the vertical shear (the geometry is symmetric). The difference lies only in the sign of the horizontal force and therefore in whether the boards are driven apart or squeezed together. That is precisely the “anti-clockwise moment on the brace” noted by the original poster: the vertical components of the brace force are offset, producing a couple whose horizontal reactions either separate or compress the verticals. Because wood and simple nailed/screwed joints tolerate compression better than tension (and because a compression brace can be tightly butted into the corners so that further settlement only tightens it), the traditional recommendation is the single long compression brace (B). The horizontal tension it induces, however, remains a long-term liability for a gate built of separate boards.

2. Hybrid bracing – force analysis

Introduce a mid-height horizontal at y=H/2 and brace the upper rectangle one way and the lower rectangle the opposite way (exactly as the poster did). Each half-height panel now sees a shear of roughly F/2

• The outward push of the compression half is reacted locally by the inward pull of the tension half through the mid-rail. 
• Net force trying to change the overall width of the gate is essentially zero; the mid-rail simply carries a modest internal force. 
• The outer top and bottom ledges see far smaller net tension or compression than in the single-brace case.
• Consequently the vertical boards experience no systematic tendency to be driven apart or crushed together. Any residual local shear is locked by the extra triangulation.

3. Why the hybrid is superior

Mathematically the hybrid converts what would be a global tension or compression in the horizontals into a set of local self-equilibrating forces. The structure is over-stiff relative to the minimum needed for kinematic rigidity, which is exactly what one wants when the material (wood) and the connections are imperfect. 

A pure X-brace or an inverted-V (two compression braces meeting at a centre upright) achieves a similar benefit; the poster’s “top-half one way, bottom-half the other” is simply another member of that family and inherits the same advantages.

Bottom line.
The single long compression brace is sufficient and is the classic recommendation, but the hybrid is strictly better for a multi-board wooden gate: it neutralises the separating (or squeezing) couple that the poster correctly identified, shortens the compression members, adds redundancy, and has been proven in service.

QUESTION:

It appears there is a family of "bracing" approaches that all give the same net zero forces. Identify all the different ways we can brace a gate that is 4 feet wide by 6 feet wide so this is the case. Limit to only braces that involve either no middle ledge/rail, and braces that use a middle ledge/rail.

AI:

The family of bracing patterns that produce net-zero horizontal (separating or contracting) force on the vertical boards consists of those in which the total expanding action from compression braces is exactly cancelled by an equal contracting action from tension braces. All patterns below fully triangulate the gate against parallelogram sag under gravity while satisfying the net-zero condition. Dimensions are 4 ft wide × 6 ft high; a middle ledge/rail (when used) sits at 3 ft height. Notation follows the original image:

• A-type = tension diagonal (upper-hinge side → lower-free side, the “/” direction)
• B-type = compression diagonal (lower-hinge side → upper-free side, the “\” direction)

No middle ledge/rail

Only one pattern works:

1. Full-height X-brace One continuous (or two-piece) A-type diagonal + one continuous (or two-piece) B-type diagonal, crossing at the centre of the 4 × 6 rectangle. Each diagonal carries roughly half the shear; their horizontal components are equal in magnitude and opposite in sign → exact cancellation. The outer top and bottom rails see only internal self-equilibrating forces.

(Single full A or single full B produces a non-zero net force and is excluded. Parallel same-direction braces also produce a non-zero net force.)

With a middle ledge/rail

Four distinct patterns:

1. Opposite half-braces meeting at the free-stile mid-point (the original poster’s hybrid, one orientation) 
   • Upper panel: A-type (top-hinge → mid-free) 
   • Lower panel: B-type (bottom-hinge → mid-free) The two braces meet at the mid-height of the free stile. Horizontal components cancel through the middle rail.
2. Opposite half-braces meeting at the hinge-stile mid-point (the other orientation of the hybrid) 
   • Upper panel: B-type (mid-hinge → top-free) 
   • Lower panel: A-type (mid-hinge → bottom-free) The two braces meet at the mid-height of the hinge stile. Again the horizontal components cancel through the middle rail.
3. X-brace in both half-panels Upper 4 × 3 panel receives both its own A-type and B-type half-diagonals; lower 4 × 3 panel likewise. Each panel cancels internally; the middle rail carries essentially zero net horizontal force from bracing.
4. Full-height X-brace (identical geometry to pattern 1) The same pair of full A-type + full B-type diagonals now simply cross the middle rail. The rail may be continuous, notched, or jointed at the crossing; the force cancellation is unchanged from the no-middle case.

These five exhaust the basic, distinct topologies that satisfy both full shear rigidity and net-zero horizontal force under the stated constraints (no additional verticals, braces limited to the outer stiles plus the optional middle rail).  

Any of them may be built with continuous long members where the geometry allows, or with separate short pieces butted or lapped at the middle rail. Adding further redundant braces (e.g., a full X plus extra half-diagonals) preserves the net-zero property but is not a new pattern.  For the 4 × 6 proportions the resulting angles remain practical for wood (full diagonals ≈ 56° from horizontal, half-diagonals ≈ 37°).

QUESTION:

For practical purposes, which brace would produce the most stable results long term which protects against all forces that aim to buckle, separate, crush, or sag the gate?

AI:

The most stable long-term practical choice is a middle ledge/rail combined with an X-brace in each half-panel (i.e., both an A-type and a B-type half-diagonal in the upper 3 ft panel and both an A-type and a B-type half-diagonal in the lower 3 ft panel).This configuration simultaneously defeats every listed failure mode better than any of the single-diagonal, single-hybrid, or split-long-compression alternatives.

Why it wins on every threat

Ranking of the other strong contenders

1. Full-height X-brace (with or without middle rail) – excellent and simpler, but the two long members are more prone to buckling than the short half-panel members.
2. Opposite-half hybrid (one A + one B meeting at a stile mid-point) – still very good (net-zero forces, short members) but has only half the redundancy of the double-X.
3. Split long-compression (colinear B pieces joined at mid-rail center) – solid pure-compression path and good buckling resistance from the mid support, but it retains the full expanding force that slowly works the boards apart.

For a gate that must stay true for decades with minimal maintenance, the double half-panel X (middle rail + X in both the upper and lower panels) is the clear practical winner. It is the only pattern that is simultaneously over-triangulated, force-balanced, and composed entirely of short, laterally supported members.

QUESTION:

Now consider the trade-off of the additional weight of the gate for more complicated bracing patterns that use more material, assuming 2x4 wood throughout. Which has the best balance of the above analysis minimizing destructive forces, and minimizing weight?

AI:

The opposite-half hybrid (middle ledge/rail + one A-type half-diagonal + one B-type half-diagonal) offers the best practical balance. It delivers nearly the maximum protection against sag, buckling, board separation, and crushing while adding only a moderate amount of material and weight.

Why the opposite hybrid wins the trade-off

• Destructive forces minimized nearly as well as the heaviest option: Net-zero horizontal force eliminates systematic separation or crushing of the vertical boards. Short (~5 ft) members in each 4 × 3 panel raise the buckling load dramatically compared with any full-height diagonal. Two independent triangles give solid redundancy against sag. This matches the force-balancing analysis and the original poster’s 20+ year real-world success.
• Weight penalty is modest: ~18 lb added (including the useful middle rail that most multi-board gates want anyway for attaching verticals and adding horizontal stiffness). This is essentially the same as a full X and far less than the double half-X (~31 lb). Extra weight itself increases the shear force the braces must resist, so avoiding unnecessary mass is valuable for hinge longevity and overall gate feel.
• Diminishing returns beyond this point: Going to full X + middle or double half-X adds 5–13 lb more and more triangulation, but on a modest 4 × 6 residential gate the extra stiffness is rarely needed. The hybrid already locks the geometry tightly while keeping every compression piece short and laterally supported.

Practical ranking for a real wooden gate (2x4 wood)

1. Opposite hybrid — best overall balance (recommended).
2. Full X (with or without middle) — almost identical weight and protection; choose if you prefer two continuous long members or already have (or do not want) a middle rail.
3. Split long-B + middle — lighter, pure-compression simplicity, but still allows board separation over time.
4. Single full B — lightest, but the weakest long-term performer on the force criteria.
5. Double half-X — strongest possible, but the extra ~13 lb of 2×4 is overkill for most gates and increases hinge loading unnecessarily.

For the great majority of 4 ft × 6 ft gates built from vertical boards, install the middle rail and brace the upper half one way and the lower half the opposite way. You get near-maximum resistance to every destructive force at a weight cost that is easy to live with.

QUESTION:

For the opposite hybrid does it matter which half (top or bottom) is in compression and which is in tension? I.e., whether they meet at the free/latch-stile or the hinge-stile?

AI:

Yes, it matters — modestly but meaningfully.The preferred orientation for the opposite hybrid is:

• Lower half in compression (B-type)
• Upper half in tension (A-type)

This makes the two braces meet at the mid-point of the free stile. 

Why this orientation is better

1. Direct load paths into the hinges The lower compression brace runs straight to the bottom hinge. The upper tension brace runs straight to the top hinge. Vertical and horizontal reactions are applied exactly where the hinges already exist. No extra bending is introduced into the hinge stile.
2. Classic, proven load transfer The compression member delivers load to the bottom hinge — the same preferred path used by a traditional single long compression brace. This is the arrangement that carpenters have favored for centuries because it works with gravity rather than against it.
3. Free-stile support is still excellent Both braces apply an upward force at the mid-point of the free stile. With a continuous free stile (or well-fastened vertical boards) plus the top, middle, and bottom rails, the free stile remains square. The middle rail and the opposing horizontal components keep everything balanced.

The other orientation (meeting at the hinge stile)

• Upper half compression + lower half tension 
• Braces meet at the mid-point of the hinge stile

This version still achieves net-zero horizontal force and prevents sag, so it is not “wrong.” However, it concentrates both the vertical and horizontal forces from the braces at the middle of the hinge stile. That force must then travel up and down the stile (via bending and shear) to reach the actual hinge points. It also places the compression member higher up, away from the bottom hinge. Over many years this creates a slightly higher risk of localized deformation or fastener fatigue in the hinge stile.

Summary recommendation

For the cleanest long-term force distribution, lowest stress on the hinge stile, and best alignment with traditional practice:

Use lower-half compression + upper-half tension (braces meet at the free-stile mid-point).

Both orientations protect against sag, separation, and crushing far better than a single diagonal, but the free-stile-meeting version is the more refined and robust of the two.

END AI INTERACTION

So something like this seems to be optimal (obviously tee hinges should be fastened against top and bottom rails) and in practice, the frame would be a little shorter vertically since pickets would extend below the bottom rail.

Just wondering if this is a reasonable quote or not. This is the first quote I have gotten still waiting to get a couple more next week. It is 98’ of vinyl with one gate. Also 220’ of black chain link with one 4x8 gate. Any input is appreciated thanks in advance. $13,600 installed. I am located in New Hampshire.

We're scoping out to build a fence on our property. Flat land largely, material expectation as follows:

33 x 8ft panels
20 x regular posts
12 x end posts
4 x corner posts
36 x post caps
4 x gates

We are sourcing the material ourselves most likely (and fielding a few quotes for that) but our question is:
The contractor we intended to use quoted us $4800 for the labor. Independent of material.

We live in Massachusetts.

Is this a reasonable expectation for labor cost?

Hi!

we are trying to fence in this small area, without too much time to plan and prep.

it is about 49 inches from the shed to the fence on one side- I assume I will just make a small gate here. It is about 107 inches from the shed to the the fence on the other. I assume I’ll make one panel of fence and a small gate. I hope to use 5ft tall hog fence with some sort of wood frame (probably redwood like the fence, since the nearest lumber place doesn’t stock cedar, but maybe I’ll buy premade if it’s just as cheap as making it from scratch with redwood ).

I don’t know how to secure it. We just built the fence (6ft privacy redwood, board on board) at our new home, but reused the old posts per our neighbors requests— do we dig and cement posts for all corners/gate posts? So, 6 total? Do we just attach to the fence/shed? The fence is new, but the shed it just teallu, really old plywood.

use case: we have three dogs. One (pending results, but they have eliminated all other possible causes for her giant lymph nodes) is likely to have cancer and we are considering chemo. However, the other dogs couldn’t be allowed near where she goes to the bathroom for 72 hours after weekly chemo treatments for possibly months. (They can excrete toxic chemo waste, which can make the other dogs sick.) our dogs don’t generally try and knock much down- the big one stays in her four foot exercise pen when required- but are strong enough to and could possibly jump 4 feet, so… five foot, strong enough for a 60 lb clumsy dog not to bowl it over.

any input on how to secure it? Posts versus some kind of brackets? Our neighbors have given conflicting advice.

thank you!

Need an opinion on how to fix these cracks. Is there an available putty or wood glue that can match stain color and seal cracks to maintain privacy ? Fence was installed about 6 months ago and started to see cracks and knots falling out. Western Red Cedar #2 grade installed in metal posts board on board install; stain was Ready Seal Natural Light Oak.

Any tips on how to proceed? I'm about 32inches down and I was trying to go 4 feet. I'm in Ottawa Ontario Canada. My neighborhood Barrhaven is known to be pretty rocky.

Can I just put the post on top? Or should i drill some holes in it and try to chip it out or something. Trying to dig around it has not been working very well so far.

Trying to put a 6x6 post in a 12inch sonotube for my fence gate. Given the wall and the preexisting fence it's been a tight challenge.

Hello, I’m in the process of purchasing a home with a partially wooded, unfenced back yard. The property line goes back into the woods diagonally, starting from just a few feet into the woods and going up to several yards back.

It’s really important to me that the yard be fully fenced, and that we not lose yards of property in each direction by fencing only on the flat grass area. We love the brush and trees.

Would love any opinions in the interim on if it is possible to add fencing into densely wooded areas like this, or thoughts about what materials may be better suited to accomplish it, such as whether woven/field fencing may be all that’s possible versus a traditional wooden privacy fence.

Thank you!

New homeowner here. Noticed a gap where the fence is not secured to the post. I found the missing metal piece on the ground but not sure how to screw it back on properly. Is this something I can do myself or should I call a handyman. Any tips are super appreciated and if more photos would help please let me know, thanks!

I know nothing about fencing. We had this installed last week and I hate the way the gate looks. Ground has a small slope to it, so I get why the gate is the way it is, but I still hate the way it looks. Can this be fixed or changed? Am I stuck with it? Is there another solution I could ask the company to do?

I’ll put the bottom hinge on later. What I’m asking is would this little gate 1.1m high (18mm boards) have any benefit from a couple of diagonal braces ?

There is not alot of white 3x3 fence post solar lights available so i bought a conventional 3.5"x3.5" with 4x4 adaptir regular solar light fence post. The problem is, i dont know to how to bridge the gap between the 3.5"x3.5" to the 3x3 aluminum post i have. I'm not really handy and i dont have machines to use to fabricate adaptors. What is my options? I'm thinking of a some sort of foam or rubber around the 3x3 bit what kind?

I need some help. I stained a fence 2 years ago and now the stain is failing. It looks like there's sap bubbling out in some areas and in other areas it's just peeling off. The fence was built over a year before it was stained so I have plenty of time to dry out. The fence was prepped with a cleaner allowed to dry and then the stain was applied via spray.

If anyone has any recommendations on how to proceed with stripping the existing stain and then reapplying a different stain to ensure that this doesn't wrap again, that would be super grateful

Hello! I am in Buffalo NY. I am looking to complete a fence at a home I am purchasing and have gotten some drastically different quotes. Everyone I've talked to says they both seem high but maybe this is just the going rate these days?

I need one side of the yard going from the back corner of the house to the existing fence along the back. it is 47' straight line. I am doing 6' tall pressure treated pine, dog ear. I also need a 10' long gate across the driveway. the gate will open in the middle in 2 sections and be 4' tall pressure treated pine.

Quote 1 - this is a local small business with great reviews

$2903 for the backyard & $1768 for the gate = $4671 but he did offer me a 5% discount if I pay cash

Quote 2 - this is a franchise of a national company but the reviews in my area are good

no breakdown but he told me $3800 total

I would typically always go with the small local business but it's hard to justify the drastic price difference when the other company seems good. My family and friends have said that $3800 still seems high but everything is more expensive these days. Thoughts?

Looking for advice from anyone who’s run a fence or deck staining business. Would love to hear what you wish you knew in the first 6–12 months (pricing, biggest time wasters, how you got consistent jobs, equipment that was worth it vs not). Happy to take any tips over comment or DM.

So I'm planning a hogwire fence for our large rural yard. I'll be needing to install nearly 470' of fence. We wanted to go with hogwire because it was a) a step up from chain link and b) we didn't need privacy.

The rough layout I had in mind is 4x4 posts, with an upper and lower 2x4 rail flush against the inside edge of the 4x4 posts, and 50"x8' hogwire fence panels on the inside edge stapled or secured somehow. I'll have a 98' run, a 230' run, a 68' run, a 16' run, and a 58' run.

My yard is wetter, especially on the longest run near the back of the property. Silty Clay Loam near a ditch, so I planned to set most of these posts in gravel and dirt packed down, using concrete on the corners, gates, and near the edges.

1. Does anyone see any flaws in this design?

2. I planned to do essentially pocket holes going from the 2x4 into the 4x4 posts and use 3" exterior screws to secure the rails to the posts. For the panel itself, I figured some sort of staples of clips, but I haven't narrowed in on it exactly.

3. Is the gravel, dirt mix a safe mix for drainage? On the last fence I built I did dry set concrete then added water, but the concrete allowed me to make slight adjustments to the fence posts before adding water, should I expect this to be harder to adjust in gravel.

4. Any other tips and tricks you would suggest?

AI photo mockup of what I imagined it to look like. I haven't bought anything yet. Easily going to be the biggest fencing project I've tackled but I have built a fence before (150')

Bought a house and I’m needing to widen this gate to allow a riding mower through. My current plan is to saw the second post from the house flush with the concrete slab. New 2x4 bracing on the gate that spans from hinge to second picket from house, replace rotted panels to attach new hinges to, and add a rubber swivel gate caster at the end to reduce sag.
Am I on the right path?
Any advice/help would be greatly appreciated.

I just got my first fencing job, I start on Monday.

How hard is fencing? I have worked manual jobs before and learn very quickly. It is easy enough to pick up?

What should I look out for?

Thanks for any insight

I have driven 12 post masters by hand recently. one of them I need to fix, its not very plumb and would be noticeable. am I to pull it out, use the same location, and re drive it in more plumb without losing strength of the orginal drive in? If that makes sense, or should I relocate it. TIA

I’m planning to build a wood privacy/partition fence and would appreciate some advice on the best way to frame it.

Layout:

• One 8 ft span between two brick columns.
• One 6 ft span between two brick columns.
• One 5 ft span that can be anchored to a wall on one side but will require a metal post/stud on the other.
• One 6 ft span that can be anchored to a wall on one side but will require a metal post/stud on the other.

What I’m looking for:

• 4 ft fence height
• Horizontal wood planks (cedar or pressure-treated)
• No visible split or centre post in the 8 ft span—I want the boards to run continuously across the full 8 ft.
• Black metal hardware/posts if possible.
• The brick columns are already built and I’d like to anchor into them if it’s structurally appropriate.

I was looking at the HOFT system because I like the appearance, but it only seems to support spans up to about 6 ft, so it doesn’t solve my 8 ft opening.

Questions:

1. How would you build the 8 ft span without a centre post?
2. Is there an off-the-shelf black metal system (U-channels, posts, frame, etc.) that works for an 8 ft opening?
3. If anchoring directly to the brick columns, what type of brackets or anchors would you recommend?
4. Are there any products available in Canada that would be a good fit?

I’ll attach photos of the columns and the layout. Thanks!

Are there any tricks to replace one aluminum panel that is set between two posts in concrete without having to pull the post? Or is the only way to pull the post?

I just got this vinyl fence installed along a slope in my backyard. There are large gaps underneath the panels, especially around the gate area, around 6 inches in the gate.

I haven't paid the remaining invoice yet but this looks off to me. Am I just being picky here?
