Ameristar Construction in Hillsborough, CA | San Mateo Construction
We provide independent Ameristar door and window service across Hillsborough, from entry-door rehangs and threshold replacement on 1940s estates to full roof and kitchen remodels that keep existing Ameristar openings intact. The thing that makes our Ameristar work different here is that we plan every opening around Hillsborough’s slope, tree, and stormwater constraints before a single jamb goes in. We also offer Ameristar service in San Mateo. We’re San Mateo Construction, and you can reach us at (855) 901-7266.
Why Hillsborough Residents Choose Us for Ameristar Service
We’ve worked with Ameristar steel and fiberglass entry doors, sliding patio doors, and storm door lines across the Peninsula for years. We know how their frame profiles, hinge hardware, and threshold assemblies behave when a Hillsborough winter pushes water against a west-facing stoop or a dry summer bakes a door set into an unshaded recess. That familiarity means we diagnose the actual failure first, then recommend repair or replacement on its merits, not on a manufacturer’s warranty script. Noel Carrington, our owner, grew up in Baywood in San Mateo and spent years working residential jobs across the county before founding San Mateo Construction, so he reads a Hillsborough jamb the way a local should. We also handle Ameristar repair in Highlands-Baywood Park. As an independent contractor, we work for the homeowner. If an Ameristar slab is sound and the frame is plumb, we rehang, re-seal, and adjust. If the bottom rail has rotted through, we tell you straight and quote a replacement. No hedging, no warranty games. Call (855) 901-7266 when you want that kind of answer.

Common Ameristar Construction Problems We Solve in Hillsborough
- Threshold and sill corrosion on steel entry doors. Hillsborough’s rainy winters pool water against poorly flashed or un-roofed stoops, and we regularly see the bottom rail of an Ameristar steel door rotting from water that never got a chance to drain. The fix usually involves pulling the threshold, rebuilding the flashing, and re-setting a new sill before the door is rehung.
- Fiberglass skin cracking at the hinge-side stile. On older 1940s – 1970s custom homes, a heavy Ameristar slab hung in a slightly out-of-plumb jamb puts constant stress on the hinge-side stile. Over a few hot summers and wet winters, the skin can crack or delaminate right where the hinge screws bite.
- Weatherstripping and sweep failure showing daylight at the strike side. We see this most on Ameristar doors set into west-facing recesses that take full summer sun then winter rain. The sweep curls, the weatherstripping hardens, and the strike side starts showing a line of light. Sometimes a fresh OEM sweep solves it; sometimes the door has moved in the opening and needs a full rehang.
- Stripped hinge and lock-prep screws in the steel. Years of slamming an Ameristar door that was never adjusted for seasonal swelling in a wooded, humidity-variable lot will eventually strip the screw holes. We re-tap, use larger-gauge fasteners where the steel allows, and reset the door so it closes without being thrown.
- Sliding patio doors that bind or leak after the deck settles. Hillsborough lots are prone to gradual settlement on slope-cut pads, and an Ameristar slider that moved cleanly a decade ago can start binding at the track or leaking at the threshold. We re-level the track, replace the rollers, and re-seal the sill before the opening causes rot in the framing below.
Ameristar Service in Hillsborough: What Local Conditions Mean for Your Equipment
On Hillsborough’s hillside streets, tree-preservation, slope-stability, and stormwater rules often mean a lot can’t simply be scraped. Door and window openings we set for Ameristar products frequently get fixed by the civil plan and arborist report before a single jamb goes in, and we build our rough openings to those locked dimensions. That’s the part a generic Ameristar page never addresses. In a neighborhood like the winding roads near Crystal Springs or the heavily wooded lots off Hayne or Ralston, an existing jamb might sit three inches out of plumb because an arborist flagged a mature oak’s root zone and the foundation wall had to jog slightly. We don’t fight that. We shim, pack, and flash to the actual opening, then hang the door so the slab sits true within it. That’s the difference between an Ameristar door that seals for fifteen years and one that binds, leaks, and rots after three. Hillsborough doesn’t reward shortcuts, and neither do we. If your lot is steep, treed, or under design review, call us at (855) 901-7266 before you assume an off-the-shelf opening will work. It usually won’t, and we’d rather tell you now than after the stucco is patched.
Ameristar Models & Products We Service in Hillsborough
We service the full Ameristar door lineup that shows up on Hillsborough homes: the steel entry door in 6-panel and flush styles, the fiberglass entry door with woodgrain texture, the sliding patio door series, and their storm and security door lines. For repairs we source OEM Ameristar hinges, sills, sweeps, and weatherstripping so the profiles and prep holes match exactly. Where OEM is discontinued, we use quality aftermarket glass units and hardware that fit without modification. We keep common Ameristar sweeps, rollers, and weatherstripping on hand for Hillsborough callouts, which means less waiting on a parts order when a door won’t seal. For full-service Ameristar sales & service, including replacement doors and windows tied into an existing opening, we’re your independent contractor across the Peninsula.
Ameristar Service Pricing in Hillsborough
Most Ameristar door repairs in Hillsborough are costed by the part and the access conditions, not by the brand name. A threshold replacement with new flashing might run a few hundred dollars; a full entry-door replacement with the old jamb pulled and a new Ameristar fiberglass slab set, flashed, and trimmed will be higher. The table below covers the larger scopes that often accompany Ameristar work here, like a re-roof that protects the door below or impact windows set into an existing opening. Every estimate includes the measurement, the opening assessment, and a written line-item quote. No change orders that appear out of nowhere. Call (855) 901-7266 to schedule yours.

FAQs – Ameristar Construction in Hillsborough
In most cases, yes. The existing opening is usually already established, and replacing the door, jamb, and threshold within it rarely triggers new arborist or civil review unless you’re also widening the opening or changing the foundation. We work within the locked dimensions from your original civil and arborist reports whenever possible. Call (855) 901-7266 and we’ll assess your specific lot.
It’s almost always a flashing and drainage problem, not a door problem. Hillsborough’s rainy winters pool water against stoops that were never flashed properly or lack adequate roof coverage, and that water wicks up into the bottom rail. The cure is rebuilding the threshold flashing and re-setting the sill, then rehanging the door. If the rail is already rotted through, replacement is the honest fix. Call (855) 901-7266 for a threshold assessment.
They can. Dry summers and heavy tree cover make exterior detailing a real wildfire concern, and door and window penetrations are part of that calculation. We set Ameristar units with proper metal flashing, sealed rough openings, and correct clearances so the assembly doesn’t create ember traps. For a full look at how we’d tie your doors and windows into your Hillsborough defensible-space plan, call (855) 901-7266.
We look at the track first, then the rollers, then the frame below the sill. If the slab and rails are sound and the failure is mechanical, we replace the rollers, re-level the track, and re-seal the sill. If moisture has eaten into the subfloor or the frame has racked from hillside settlement, replacement is usually the better spend. For customers needing Ameristar in Burlingame or nearby, we bring the same expertise. On a hillside lot off a steep wooded street in Hillsborough, we replaced a storm-battered Ameristar steel entry door whose bottom rail had rotted from years of rain splashing off an unflashed stoop. We rebuilt the threshold and flashing, rehung a new Ameristar fiberglass slab in the existing jamb, and re-set the sweep and weatherstripping so the strike side sealed tight. That’s the same judgment we’d apply to your slider. Call (855) 901-7266.
Usually yes. Ameristar doors and windows can stay in place while we re-roof, remodel a kitchen, or replace impact windows provided the existing openings are sound and properly flashed. We protect them during construction and re-seal all penetrations around them when the larger scope finishes. Call (855) 901-7266 to walk through your specific remodel plan.
