Why Gatewood Fence & Gate Is Mountlake Terrace’s Preferred Gate Parts & Welding Company
Hal Gatewood has been fixing gates since 2001, and he still puts his name on the shop and on every invoice. That matters in Mountlake Terrace, a city of roughly 22,000 people where homeowners still wave at each other from the driveway. You’re not calling a dispatch queue when you call us. You’re calling someone whose address is published and whose crew works your streets every week. We know that the original post-WWII ranches off 228th Street SW were built with cedar posts set directly in clay, and we know what that clay does to a post over 60 winters. That’s not general contracting knowledge. That’s Mountlake Terrace knowledge.
Our Mountlake Terrace customers call us back because the person who shows up is the same person who quoted the job, and because every job carries the 90-Day Done Right Promise in writing. If it’s not done right, one call brings Hal back. No runaround, no fine print, no “that’s not covered.” We also offer $40 off any repair over $200, no trip charge inside the county, and a free second opinion on any written estimate you’ve received from another company. Seniors and veterans get a permanent 10% discount, no coupon clipping required.
Our Gate Parts & Welding Services in Mountlake Terrace
Hinge Replacement
In Mountlake Terrace, hinge failure is rarely about the hinge itself. It’s about the wood behind it. Original 1950s and 60s gate posts were often set without proper drainage, so the hinge screws gradually lose their grip as the post softens from the inside. We replace the hinge with heavy-gauge hardware and, when needed, sister in new material or replace the post entirely so the hinge has something solid to bite into. A hinge replacement on a standard single-swing gate in Mountlake Terrace typically runs $180-$340, including hardware and labor.

Post Replacement
This is the service we do more than any other in Mountlake Terrace, and it’s the one that separates real repair from a temporary patch. The city’s clay-bearing soils expand and contract through the wet season, heaving posts out of plumb year after year. We hand-dig the old footing in tight side yards where equipment can’t reach, set a pressure-treated post in gravel for drainage, and pour a proper concrete collar. For a typical 4×4 or 6×6 gate post, expect $350-$650 depending on depth, access, and whether the old footing is poured concrete or rotted wood buried below grade. The price is quoted and agreed before we touch a shovel.

Rail Repair
Chain-link and wood rail failures on Mountlake Terrace gates usually show up as a panel that sags in the middle while the hinge side still looks fine. The top rail has either rusted through, pulled loose from a rotted post, or bent under years of tension. We cut out the failed section, weld or bolt in new rail, and reset the gate so it swings square. Most rail repairs run $150-$280, though a full panel rebuild with new tension bands and tie wire lands closer to $400-$550. We’ll tell you which one your gate actually needs before we write the number down.

Custom Welding
Not every Mountlake Terrace gate problem fits a catalog part. When a steel frame has cracked at the weld, a bracket has snapped, or you need a custom latch plate fabricated to match a gate that hasn’t been made since Eisenhower was president, we weld it on site. Our truck carries a portable MIG welder, so the repair happens in your driveway while the gate stays hung. Custom welding and fabrication typically runs $120-$400 for a single seam or bracket, depending on material thickness and accessibility. We’ll show you the break before we fix it, and we’ll stand behind the weld with the same 90-day written promise.

Trusted Brands We Service in Mountlake Terrace
We service and stock parts for the brands most common on Mountlake Terrace gates, including Linear, Viking, and Ghost Controls openers, plus the older DoorKing units still running on some of the larger double-swing driveway gates. The 98043 housing stock skews toward single-swing and small double-swing gates, so we carry the hinge kits, rollers, latch assemblies, and control boards that match what’s actually installed here, not what a warehouse in another state assumes you have. That means fewer return trips for us and a faster repair for you. If the brand on your opener isn’t listed, call anyway – if it runs on 12V or 110V, we can likely service it or tell you honestly whether it’s reached the end of its life.
Common Gate Parts & Welding Problems We See in Mountlake Terrace Homes
- Clay heave pushes posts out of plumb every winter. Mountlake Terrace sits on a glacially deposited plateau with heavy clay that drinks the region’s 38 to 42 inches of annual rain, then expands. A gate that latched fine in September can be dragging on the driveway by February. We re-set posts below frost line and pack the footing with gravel so water drains instead of pooling at the wood.
- Original 1950s and 60s cedar posts rot at the soil line. The above-ground wood can look perfectly sound while the base is mush. We probe every post before quoting a hinge swap, because fixing the hinge without the post means fixing it twice. This is the single most repeated mistake we find in Mountlake Terrace gate work done by out-of-town crews.
- Narrow side yards make post work harder than it looks. Many 98043 lots are 50 to 60 feet wide, which puts gate posts in tight strips between the driveway edge and the property line. Hand-digging and repouring in those spaces is slow, careful work, but it’s the only way to do it without chewing up your landscaping or your neighbor’s fence.
- Lake Ballinger-adjacent properties hold water into summer. The east edge of Mountlake Terrace sits in a lower-drainage zone where the water table stays elevated for months after the winter rain stops. Gate posts in those blocks show accelerated base rot and hinge corrosion even when the gate looks fine at eye level. We look below the soil line before we quote anything.

FAQs - Gate Parts & Welding in Mountlake Terrace
Your gate sags every winter because the clay soil under the hinge post expands when it absorbs rain, pushing the post slightly out of plumb. Mountlake Terrace gets most of its 38 to 42 inches of annual rainfall between October and April, so the ground is doing a slow heave-and-settle cycle all season. Each cycle pulls the post a little further from true, and by spring the gate drags. The permanent fix is re-setting the post with a gravel drainage bed below the footing, not adding another hinge shim. Call (877) 610-2993 and we’ll check the post before selling you anything.
Probe the base of the post at soil line with a screwdriver; if it sinks in more than a quarter inch, the post is rotted and needs replacing. Most original cedar gate posts in Mountlake Terrace were set in clay with no drainage gravel, so 60 years of wet winters have worked on them from the bottom up. A hinge replacement on a rotted post is wasted money – the new screws have nothing to hold. We probe every post before we quote, and we’ll show you what we find honestly. For an exact assessment, call (877) 610-2993.
Yes, in most cases we can weld a new steel frame or reinforce the existing rails on your chain-link gate right in your Mountlake Terrace driveway, and it’s almost always cheaper than a full replacement. A typical reinforcement with new rail and welded corner brackets runs $250-$500, whereas a new custom-sized gate can run $800 and up. We’ll tell you plainly whether your existing galvanized frame is worth saving or whether the rust has compromised too much metal. Estimates are free – call (877) 610-2993.
For the larger acreage lots on the outer edges of Mountlake Terrace, we recommend a heavy-duty linear or ram operator rated for wide, heavy gates, with a minimum 1/2 HP motor and a battery backup. If your entrance is far from the house, solar panels can power a 12V operator where running mains is impractical, but we size the panel and battery bank to your gate’s actual daily cycle count, not a generic template. A new operator install on a wide driveway gate typically runs $1,200-$2,800 including the motor, mounting, and safety edges. Call (877) 610-2993 for a free measure and a written price.
Mountlake Terrace was built out almost entirely as a planned suburb in the 1950s and 60s, so an unusually high proportion of original gate posts are all hitting the 60 to 70 year failure threshold at the same time. Add the heavy clay soils that hold moisture through the winter and you get a city-specific pattern: wholesale post rot and heave, all on the same replacement cycle. Lynnwood and Shoreline developed more gradually, so their gate failures are staggered. Here, we’re effectively working through an entire community of aging gate infrastructure at once, and that’s exactly what we’ve been doing for decades. Call (877) 610-2993 if your post has reached its limit.
In most cases, yes. We keep Mountlake Terrace on our daily route, so same-day service is common for hinge, latch, and rail work. Larger post replacement and custom welding jobs may schedule a day or two out, but we’ll tell you the first available time when you call, and the person answering is a live human, not a recording. Call (877) 610-2993 and we’ll get you on the schedule.
If your Mountlake Terrace gate is dragging, sagging, rusted, or simply won’t close, call (877) 610-2993. Hal Gatewood and his crew work this city every week, know the soil and the housing stock, and put the 90-Day Done Right Promise in writing on every job.
