AfterFast, Reliable Gate Installation Across Riverton
A new gate in Riverton, WA typically runs $1,400 to $6,800 installed, depending on whether you’re hanging a single pedestrian gate off a 1960s rambler or automating a double swing gate for a contractor yard off the Duwamish industrial fringe. That price includes the gate itself, posts, hardware, and labor, and it’s quoted in writing before we touch anything. Call (877) 610-2993 and a live person picks up, day or night.
We work 98168 constantly. Hal Gatewood has been running Gatewood Fence & Gate since 2001, and his crew knows the difference between a post set in Riverton clay and one set three miles west in SeaTac’s sandier till. That difference decides whether your gate sags again in two years or stays square for twenty.
Why Gatewood Fence & Gate Is Riverton’s Preferred Gate Installation Company
Most gate companies in King County won’t tell you the truth about an old post. We will: a gate sags in the hinge post, not in the middle, and in Riverton that post has been sitting in wet clay since Eisenhower was president. The bulk of homes here date to the 1950s and 1960s, which means original pressure-treated or fir posts are now 40 to 60 years old and rotting at ground level even when the visible wood looks fine.
Hal’s name is on the shop and on every invoice. The address is published, the license number is there for anyone to look up, and if something isn’t right, one call brings him back under the 90-Day Done Right Promise. No runaround. Written on the job, not buried in fine print.
Calls are answered by a live person 24 hours a day, seven days a week. Not a voicemail, not an automated queue. If you’re in the middle of a gate failure at 9pm on a rental off 24th Ave S, you get a person who can actually do something about it.
Our Gate Installation Services in Riverton
Driveway Gate Installation
A driveway gate on a Riverton rambler usually sits on a modest lot with a wood privacy fence already around it. The most common job we do here is replacing a single-swing driveway gate that’s been dragging on the concrete for two winters straight. In Riverton’s heavy clay, the post has usually rotted below grade, and that’s where we start, not with the panel. You can’t hang a straight gate on a leaning post and expect it to last.
Pedestrian Gate Installation
Pedestrian gates in Riverton get more abuse than driveway gates because they’re used ten times a day instead of twice. On rental properties especially, the original latch is long gone and somebody’s wrapped a bungee cord around the frame. We build pedestrian gates with the same post-footing care as the big ones, because a 3-foot gate that sags is just as annoying as a 12-foot one. New hardware, new hinges, and a post set on a proper footing for clay soil.
Sliding Gate Installation
Sliding gates make sense on the smaller lots common to Riverton’s 1950s buildout, where there’s no room for a big swing arc over the driveway. They also show up on the light-commercial side of 98168: storage parcels, fleet-parking lots, and small contractor yards along the Duwamish industrial fringe. A slide gate’s track has to handle the runoff from 38 inches of annual rain, so we set the track with drainage built in, not as an afterthought.
Swing Gate Installation
Swing gates are the bread and butter in Riverton because most of the housing stock was built for them. But the original footers were poured small and shallow, and 50 years of expansive clay movement has cracked and tilted many of them. When we replace a swing gate, we don’t just swap the panel. We check the plumb of the post, dig out the old footing if it’s failed, and set a new one deep enough to stay put through wet winters and dry summers.
We also do double gates, which show up on wider driveways in Riverton’s larger lots along the Duwamish corridor. A double swing gate doubles the hardware and doubles the places a bad post can ruin everything, so we treat each leaf like its own gate.

Trusted Brands We Service in Riverton
We install and service operators from Linear, Viking, Ghost Controls, and DoorKing, among others. For Riverton customers that means we don’t have to order in a mystery part and wait a week. We keep common boards, arms, remotes, and safety edges stocked so a retrofit on an old swing gate doesn’t turn into a two-visit job. If you’ve got a 1990s operator that’s finally quit, we’ll tell you honestly whether it’s worth a retrofit or cheaper to replace.
Common Gate Installation Problems We See in Riverton Homes
- Rotted hinge posts at ground level. In Riverton’s clay, the post holds moisture against the wood all year. By the time the gate drags on the driveway, the post is usually gone 8 to 12 inches below the surface, even if the wood above still looks solid.
- Cracked and tilted concrete footers. The expansive clay under Riverton heaves with every wet season and shrinks in the dry summer months. A 1950s footer set shallow in that soil will crack and lean, throwing the gate frame out of square so new hinges alone won’t fix it.
- Failed operators on neglected rentals. Absentee ownership tied to SeaTac-area rental corridors means Riverton gates often get no maintenance until they stop working completely. Obsolete control boards, seized hinges, and corroded latch strikes from constant winter rain are the usual package.
- Out-of-square frames from years of moisture saturation. Wooden gate frames in Riverton rack and sag because they never fully dry out. The fix isn’t a turnbuckle and a prayer; it’s a properly re-built frame on sound posts.
Pricing for Gate Installation in Riverton, WA
A pedestrian gate in Riverton runs $600 to $1,600 installed. A single swing driveway gate runs $1,400 to $3,200. A sliding gate for a small lot or contractor yard off the industrial fringe typically lands between $2,800 and $5,400. A double driveway gate with an operator is $3,800 to $6,800, depending on width and automation.
What moves the number is the post work. If the old concrete footer is cracked and has to be dug out and re-poured, that’s labor and material added to the job. If the post is sound, the job is faster and cheaper. Either way, the price is quoted and agreed before we start, and it doesn’t change at the door. We offer no trip charge inside the county, $40 off any repair over $200, and a permanent 10% discount for seniors and veterans. Call (877) 610-2993 for a free written estimate.

FAQs - Gate Installation in Riverton
Because Riverton’s 98168 ZIP sits on heavy clay that holds moisture against the post all year long, while neighboring SeaTac and Burien sit on sandier glacial till that drains faster. That constant moisture accelerates rot at ground level and under the surface, so a post that looks fine from 3 feet up can be structurally gone below grade. Call (877) 610-2993 if your gate’s dragging or leaning; we’ll check the post before you spend money on new hardware.
Sometimes, yes. If the control board has terminals for safety inputs and the motor’s still pulling fine, we can often wire in new photocells and a current-sensing edge to bring it closer to modern standards. But if the board is obsolete and the hinges are seized, a retrofit is money thrown at a gate that’s already failing. We’ll tell you which one you’ve got.
It’s common in Riverton, but it’s not normal and it won’t fix itself. The clay under the gate swells with winter rain and the post moves just enough to let the frame rack and the gate edge scrape. That’s a sign the post or footing is failing, not a seasonal quirk. Leaving it means more drag next year and a full post replacement eventually. Call
For most residential gate post replacements, no permit is required in unincorporated King County or in Riverton’s 98168 area, as long as you’re replacing like for like and not changing the fence line or height. Commercial gates on the Duwamish industrial fringe sometimes fall under different rules depending on the property’s zoning and whether the gate is part of an access-controlled driveway. We can verify what applies to your specific property before we start.
That depends on gate weight and cycle count, but for a small slide gate on a commercial yard we typically recommend a heavy-duty linear arm or rack-and-pinion operator rated for daily commercial use, not a residential swing arm pushed past its limits. A yard gate that cycles 40 times a day will kill a residential operator in a year. We’ll spec the right unit for your actual usage, not the cheapest thing that fits.

What Riverton Customers Say
Trusted by homeowners across Riverton and surrounding areas.
"Driveway gate had been dragging for two years and two other companies told me the whole thing needed replacing. Hal reset the posts, rehung it and it swings like it did when it went in. A fraction of the price of a new one."
"He came out in the snow to get our gate closed after a delivery lorry clipped it, then came back in the spring to do the proper repair when the ground had thawed. Only charged for the second visit."
"The fence is excellent and it was fairly priced. He is not quick to answer email, so if you need him, ring. He always picks up the phone."
