Your Composite Sliding Installation Checklist - Step by Step
Two people. A few hours. Our step-by-step process. Steel and wood - no crane needed. You can do this.
Step 1: Measure where the gate will go
Measure twice. Write it down.
- When measuring, allow for double the distance of the gate size + 2.5' for automated gates (Example: 16' sliding gate, allotted area 34.5')
- Mark the location where the posts will be installed with white paint
- ⚠️ Call 811 to have underground utilities located before you dig
Step 2: Dig the post holes
- Once the area has been cleared and there are no obstructions, dig the post holes
- We recommend an 18" x 18" x 36" hole for each post (depth can vary depending on how solid the ground is)
- Use crushed base rock at the bottom of the hole for extra help with drainage and support for posts
Step 3: Find the absolute highest elevation in the gate's path
- Use a tape measure and a level to determine where the highest elevation is in the path of the gate
- Once the highest point along the path of the gate has been found, set the posts to that height and level across to the next post. Height of posts from highest elevation point provides a minimum of 2" clearance above the gate
- Top of post 74" plus highest elevation point for Flat Top Gates (the posts might be higher than this depending on the elevation point)
Step 4: Attach "V" track
- The "V" track should be set behind the support posts 5" away to the center of track for non-wood gates, and 6" away to center of track for wood gates
- The track can be set using Blue concrete screws, expansion bolts, sleeve anchors or epoxy with threaded rod (the type of anchoring is dependent on your ground material)
Step 5: Attach overhead roller supports
- Clamp overhead roller supports to the top of the post roughly 1" down from the top (to accommodate the post cap)
- Drill (2) ⅜" holes and bolt on the support with provided bolts
Step 6: Set gate
- We recommend using 2 or more people to set the gate
- Attach wheels to the wheel housings
- Align the gate so that the wheels ride on the V track
- Slide the gate into the overhead roller supports
- Use a level to make sure the gate is level then tighten down the roller supports
Step 7: Gate stops
- Roll the gate to the complete open position (so that the end of the gate is flush with the inside of the support post)
- Attach the "V" track stop so that the gate cannot slide past the maximum open position using provided self-tapping screws
- Roll the gate to the close position (so that the gate ends are flush with the outsides of both posts)
- Attach the close position stop using the provided stop to the bottom of the open side of the gate

From Order to Operating: Your Composite Sliding Gate Timeline in Washington
Most projects take 6–14 weeks. Here's what happens when.
| Phase | Duration | Details |
|---|---|---|
| Permit approval | 1-3 weeks | DC DCRA permit required; historic preservation review in many neighborhoods. Plan accordingly. |
| Fabrication | 2-3 weeks | Custom fabrication after design approval |
| Shipping | 3-7 days | LTL freight; lift-gate trucks available for easy curbside unloading; kits can be unloaded piece by piece on the truck for lighter handling |
| Site preparation | 1-2 days | Excavation, concrete footings, utility trenching |
| Installation | 1-2 days | Gate hanging, operator mounting, electrical, commissioning |
Total project timeline: Typically 6–14 weeks from initial consultation to operating gate, depending on permit speed and fabrication complexity.
Washington scheduling tip: DC permitting is notoriously slow (DCRA). Start the permit process 6-8 weeks before your planned installation date. Some installers won't even quote DC projects without a pre-application meeting with DCRA.

Permit Requirements in Washington
Permits are a pain. But skip them and you risk fines, removal, or voided insurance. Not worth it.
DC DCRA permit required; historic preservation review in many neighborhoods
What you usually need (DC):
- Drawing showing where the gate goes
- Gate specs (material, size)
- Opener specs (safety rules for automatic gates)
- Electrical plan
- Emergency access plan (fire dept may need a key box)
How long: 1-4 weeks usually. Historic areas or coastal zones may add 2-6 weeks.

Specs That Matter: Composite + Sliding
Composite At a Glance
| Weight | Light to medium (60-180 lbs per panel) |
| Rust | High - no rust, no rot, holds up in sun |
| Upkeep | Clean once a year. That is it |
| How long it lasts | 25-35 years |
| Best for | Near the coast, Low upkeep, Looks like wood, Budget-friendly |
Composite looks like wood but won't rot, warp, or attract termites. It's the best of both worlds.
Sliding Gate At a Glance
| Min width | 10 ft |
| Max width | 40 ft |
| Space needed | Space beside fence for gate to slide - same as gate width |
| Best for | Flat or gentle slopes, Wide openings |
| Opener type | Chain or gear drive |
Sliding gates slide sideways. No swing space needed. Perfect when you're short on room.
When to Choose Composite
✅ Choose when:
- You want wood look without wood upkeep
- Coastal or humid. You want durability.
- Low upkeep. Install and forget.
- No rot. No bugs. Holds up in sun.
❌ Think twice when:
- You need max security. Composite is lighter than steel.
- You want 50+ years
- Opening over 24 ft. Composite can flex.
💡 Pro tip: Composite works with modern homes, coastal properties, and vinyl fencing. Looks like wood. Lasts longer.
Sliding Gate: What to Know
Best for: Wide openings. Over 16 ft. No room for swing? Sliding works. Handles 20-40 ft easily. Good on gentle slopes.
⚠️ Watch out: Forgetting where the gate goes. It needs a clear path beside the fence. Same length as the gate. A wall or planter 10 ft away? A 16-ft sliding gate will not fit.
💡 Pro tip: Better track and rollers cost $200-$400 more. But they are quieter. Neighbors will thank you at 6 a.m.
Composite vs Other Materials for Sliding Gates
How does composite stack up? Here's the side-by-side comparison.
| Factor | Composite | Steel | Wrought Iron | Aluminum | Wood |
|---|---|---|---|---|---|
| Weight | Light to medium | Heavy | Heavy | Light | Medium |
| Lifespan | 25-35 years | 30-50 years with good care | 50-100+ years with good care | 30-40 years | 15-25 years. Depends on wood type and weather |
| Maintenance | Clean once a year. That is it | Check once a year. Touch up paint every 3-5 years | Check twice a year. Repaint every 2-3 years | Clean once a year. Little else | Seal or stain every 1-2 years. Check hinges often |
| Mid-range cost | $4,200-$7,800 | $5,800-$10,500 | $7,000-$13,000 | $4,500-$8,500 | $3,800-$7,000 |
Local Considerations for Washington
Every market is different. What works in one city may cost more or require different permits in another. Here's the Washington breakdown.
State: DC Climate zone: Temperate Permits: DC DCRA permit required; historic preservation review in many neighborhoods
Washington Properties & Styles
Typical lots: Urban row house lots in Georgetown and Capitol Hill, larger parcels in upper Northwest (Cleveland Park, Spring Valley), suburban lots in McLean/Great Falls (VA side) Popular gate styles: Historic wrought iron (Georgetown, Kalorama), Federal-style ornamental designs, modern steel in new townhouse developments
HOA & Architectural Review
Heads up: DC Historic Preservation Review Board has jurisdiction over many neighborhoods. Expect 2-4 months for design approval in historic districts. Even non-historic neighborhoods may have ANC review.
Composite in Washington's Climate
Composite is ideal for temperate climates. Minimal maintenance - an annual wash is usually sufficient. The material will not rot, rust, or require sealing like wood or metal alternatives.
Washington Cost Factors
Labor and material costs in Washington run approximately 15% above the national average. Use this when comparing quotes - a $10,000 gate in Texas might be $12,000–$14,000 in Washington.
Local Installer Tip
DC permitting is notoriously slow (DCRA). Start the permit process 6-8 weeks before your planned installation date. Some installers won't even quote DC projects without a pre-application meeting with DCRA.
What Installers Wish You Knew (Before You Sign)
Methodology note: These tips come from common real-world install patterns. Always double-check local code, utility clearances, and your driveway layout before you start.
💡 Composite Sliding
Composite sliding gates need a steel bottom rail in the track. Like wood. Composite panels on top. Steel below. Tracks well.

Real Projects: Here's What Actually Happened
Real Projects: Composite Sliding in Washington
Here's what actually happened. A Washington homeowner with a urban row house lots in georgetown and capitol hill chose a composite sliding gate for their 14-ft driveway opening.
What they got: Single sliding gate. Plug-in opener. Keypad. 2 remotes. Cost: $4,800-$9,000 (mid-range) Time: 2-3 weeks to build + 1-2 days to install Climate note: Composite is ideal for temperate climates.
What they'd do differently: "Get the intercom from day one. Adding it later meant re-trenching for the cable."
Here's Something Cool
V-groove track with stainless rollers costs $200-$400 more but eliminates the grinding noise neighbors complain about.
