A timber garden gate hangs true when posts are solid, hinges set level, and a 6–10 mm gap lets the latch close cleanly.
Ready to set a neat, swing-smooth gate that lasts? This guide shows clear steps, simple checks, and field tips that stop sag, scrape, and slam. You’ll size the opening, set posts that stay put, position hinges with confidence, and finish with a latch that hits the keep first time, every time.
What You Need And Why
Match hardware and timber to the gate’s size and weight. Large leaves call for longer straps, bigger fixings, and deeper posts. Pick exterior-grade screws and treated wood for anything near soil or splash. Keep measurements handy and work in a tidy sequence so each step builds on the last.
| Item Or Check | Recommended Spec | Reason |
|---|---|---|
| Posts | 100×100 mm (4×4) or 125×125 mm (5×5) | Resists twist and slump under wind and weight |
| Post Depth | 600–800 mm or ≥ one-third of post | Limits frost lift and wobble |
| Footing | 100 mm gravel base + concrete bell | Improves drainage and grip |
| Gate Width | Up to 900 mm for single leaf | Cleaner swing and easier latch line |
| Hinges | 2 heavy strap or T-hinges (add a third on heavy leaves) | Spreads load across frame rails |
| Fixings | Exterior screws or coach screws | Holds under shear and pull-out |
| Side Clearance | 6–10 mm each side | Allows seasonal swell without bind |
| Ground Clearance | 50–75 mm | Keeps lower rail out of splash and gravel |
| Latch & Stop | Thumb or ring latch + timber stop | Repeatable close and quiet hit |
| Finish | Breathable stain or exterior paint | Shields end grain and joints |
Plan The Opening
Measure the span at top, middle, and bottom. Note any taper. If the posts pinch or flare, correct the line before you hang. Run a string line between posts so faces align. Check the swing arc for bumps, pavers, roots, or turf rise. Trim the high spots now so you keep a steady ground gap.
At damp sites, use timber rated for ground contact and raise post bases off soaked soil with a gravel collar or metal shoe. That small lift cuts standing water around the base and helps the post last.
Hanging A Timber Garden Gate — Step-By-Step
1) Set Posts That Don’t Move
Dig each hole 250–300 mm wide and deep enough to bury at least one-third of the post. Drop in 100 mm of clean gravel and compact it. Stand the post plumb in both directions. Brace with stakes and battens. Pour concrete so it forms a bell at the base and a slight crown on top. Re-check plumb while the mix sets. Give the footing a full cure before you hang heavy hardware.
2) Pick The Right Hinges
Strap or T-hinges are the go-to for timber leaves. Longer straps share weight along the rail, which keeps joints tight. Hook-and-band types let you tweak height later with a turn on the hook. Choose hot-dip or stainless where rain and sea spray are common. Pair hinges from the same kit so the knuckles align and the pins match.
3) Fit Hinges To The Leaf
Lay the leaf on padded trestles. Set the top strap so the knuckle sits flush with the edge and lines up with the top rail. Mark, pilot, and fix. Place the lower strap close to the bottom rail to widen the spacing. On a heavy or wide leaf, add a third strap near the lower third to spread load even more. Drive fixings square so heads sit tight.
4) Offer The Leaf To The Hinge Post
Prop the leaf on 50–75 mm blocks to set the ground gap. Lift the straps to the post and mark hole positions. Pilot to match shank size. Fix the top hinge first so the knuckle bears firmly against the post face, then fix the lower hinge. Swing the leaf and watch the side gap from top to bottom. Adjust with a thin packer under a strap if the gap shows a taper.
5) Fit The Latch, Stop, And Keep
Close the leaf, mark a clean stop line, and fix a timber stop strip to the post. Mount the latch at hand height, then place the keep so the tongue meets the plate without lifting the leaf. Test from both sides. Add a drop bolt for storms or pet traffic. A soft closer or short chain helps in gusty spots.
6) Seal, Paint, And Protect
Coat fresh cuts with end-grain sealer. Paint or stain on a dry day, working into joints and edges. Cap post tops so water sheds. Keep mulch and soil pulled back from the post base to cut wetting and decay.
Clearances, Heights, And Local Rules
Side gaps of 6–10 mm stop bind when timber swells. A ground gap of 50–75 mm keeps the lower rail away from splash and gravel. Where a boundary fronts a road or pavement in England, many front boundaries stay near 1 m while rear runs often sit near 2 m unless a council says otherwise. Check the wording that applies where you live and watch for listed buildings or conservation zones.
See the Planning Portal guidance for general height limits and exceptions. For timber near soil, the AWPA Use Category note explains when ground-contact grade is the right pick.
Tools And Materials Checklist
Lay out the gear before you open a bag of concrete. A neat site saves time and keeps errors at bay.
- Shovel, digging bar, and post hole auger
- Bagged concrete and clean gravel
- Level (600 mm+), long straightedge, and string line
- Clamps, wedges, and temporary braces
- Drill/driver, pilot bits, and impact socket
- Exterior screws or coach screws sized to hinge plates
- Handsaw or circular saw for trims
- Paint or stain, brush, and end-grain sealer
- Safety kit: gloves, eye and ear protection, dust mask
Build A Strong, Stable Frame
A light frame twists and droops. Use kiln-dried rails and stiles, and brace from the lower hinge corner up to the latch-side top corner. That diagonal holds the rectangle. Fix cladding boards with a small gap so water sheds. If the frame starts to rack later, tension a steel strap or add a turnbuckle to the brace to pull the leaf back to square.
Prevent Sag, Scrape, And Squeak
Hinge Positioning
Keep the top strap close to the top rail and the lower strap near the bottom rail. The wider the spacing, the better the leaf resists sag. Drive fixings straight and to full depth. If screws don’t bite hard, step up a gauge or swap to coach screws for a deep thread.
Post Bracing In Wind
In gusty sites, add a short diagonal from post to fence rail to share loads. Where a single leaf runs wide, fit a small wheel at the latch end to carry weight on paving. Pick a wheel height that clears puddles and gravel.
Quiet, Clean Latch Action
Stick felt pads on the stop where the leaf meets the post. Set the keep so the tongue slides in without lift. Oil hinge knuckles once each season and wipe off any grit that collects around pins and straps.
Smart Layout Choices
On sloping ground, put hinges on the high side so the leaf swings downhill and clears the grade. Where both sides sit level, swing into the space with fewer obstacles. Keep the latch on the garden side when privacy matters. For kids and pets, pair a latch with a drop bolt and add a lower stop so noses and paws don’t push through gaps.
Concrete, Gravel, And Drainage Tips
Use clean gravel under each post to give water somewhere to go. Form a bell at the base of the footing so uplift forces don’t pull the post. Shape the top of the footing to shed rain away from the timber. In clay, widen the bell for extra grip. In sandy soil, use a deeper embed or a larger section post so the hole walls don’t shift under load.
Care And Seasonal Checks
Wood moves through the year. Run a quick check each spring and after storms. Tighten loose fixings. Touch up coating on edges and end grain. Clear soil, mulch, and leaves from the post base. Renew felt pads on the stop. Oil hinges and test the latch from both sides. These small jobs keep the swing smooth and the line true.
Common Mistakes To Avoid
- Shallow posts or no gravel base under the footing
- Hinge knuckles out of line, which scrubs the pin
- No stop strip, so the latch hits the post edge
- Side gaps too tight for wet seasons
- Interior screws used outdoors
- Skipping end-grain sealer on fresh cuts
- Painting while timber is wet, trapping moisture
Quick Reference Troubleshooting
| Symptom | Likely Cause | Fix |
|---|---|---|
| Sags at latch | Hinge spacing too tight; no diagonal brace | Move lower hinge down; add brace; fit a wheel |
| Scrapes ground | Post moved; grade swelled | Lift leaf on hinges; trim grade; check footing |
| Latch binds | Gap too small; keep misaligned | Plane edge; reset keep; add a stop strip |
| Hinges squeal | No oil; knuckles rubbing | Oil pins; shim strap to align |
| Gate rebounds | No stop or soft pad | Fit a stop and felt pads |
| Fixings pull out | Undersized screws or soft timber | Step up gauge; swap to coach screws |
| Post wobbles | Footing too small or shallow | Add braces; re-set with larger bell |
| Finish peels | Painted over damp wood | Dry the timber; sand; re-coat with breathable finish |
Why These Specs Work
Deep posts, bell footings, and gravel bases fight frost lift and wobble. Broad straps shift weight along the rails instead of one tight point. Side and ground gaps prevent scrape when timber swells after rain. Stops and keeps give a repeatable hit so the latch closes with a neat click. Exterior-rated screws and coatings hold up to sun and wet for many seasons.
Project Pace, Handling, And Safety
Work with a mate for lifts. Wear eye and ear protection, gloves for treated timber, and a mask while cutting. Keep kids and pets away during digging and mixing. Clean tools before the mix sets. Stack offcuts and screws in a tub so nothing ends up in the grass.
Finish With Confidence
Before you pick up the broom, run three checks: swing, gaps, and latch feel. The leaf should move smoothly, hold a steady side gap from top to bottom, and shut against the stop with one light push. Take photos of plumb posts and hinge lines before you backfill around the footing tops. Keep hardware instructions in a zip bag behind a fence rail so tune-ups stay easy down the line.
