Therma-Tru Construction in San Martin, CA | Iron Beam Contractors
We provide independent Therma-Tru door installation and repair across San Martin, CA, handling everything from slab swaps to full entry systems with sidelites and transoms. What makes our work different here is simple: we plan every Therma-Tru job around Santa Clara County permitting and the expansive clay soils that make door openings move seasonally on rural parcels. We’re not a Therma-Tru dealer. We’re a San Martin General Contractor who’s reset more shifted jambs on San Martin ranch homes than we can count. Call (833) 756-5936 for a free estimate.
Why San Martin Residents Choose Us for Therma-Tru Service
Therma-Tru in Gilroy and throughout this valley means fiberglass doors that hold up to UV better than wood and don’t warp like hollow steel. But the installation is where things go sideways if the contractor doesn’t know what the ground here does. Nolan Driscoll, our owner, grew up in the Friendly Hills area of Orange and spent years working with Southern California clay before building Iron Beam Contractors. That background matters in San Martin, where winter moisture swells the soil and summer heat bakes it dry, and every exterior opening has to be flashed and shimmed for movement. We also carry Therma-Tru OEM sills, sweeps, and hardware for the models most common on San Martin properties, which means fewer trips to order parts and less waiting on a door that won’t latch.
One contractor, every phase. If your Therma-Tru entry needs work and you’ve also got a kitchen countertop or bathroom on the list, we sequence the projects under one agreement. No coordinating three different crews from three different companies.

Common Therma-Tru Construction Problems We Solve in San Martin
- Chalky, faded fiberglass skins. South- and west-facing doors on San Martin ranch homes and estate properties take direct afternoon sun through long, dry summers. Dark factory finishes on Smooth-Star and Fiber-Classic doors start showing their age within a few seasons. We can refinish when the skin is sound, or replace the slab when the fade is past saving.
- Threshold swelling and drag. Rural lots here run on irrigation, and overspray combined with winter frost means the bottom of a Therma-Tru door picks up moisture. Woodgrain textured skins and painted stiles are the first to swell, and suddenly the door scrapes or won’t seal. We replace the threshold, assess the sweep, and fix the drainage pitch at the entry so it doesn’t come back in six months.
- Multi-point lock misalignment. Expansive clay soil under a San Martin slab or foundation shifts with seasonal moisture. When the jamb moves even an eighth of an inch, a Therma-Tru multi-point system drops out of alignment. Owners will force the handle, which wears the gearbox. We reset the opening, not just the hardware, because adjusting a lock to a moving frame is a band-aid.
- Leaking sidelite and gasket seals. Dry-rot and cracked glazing gaskets around Therma-Tru sidelites let wind-driven rain through, and on barn-and-shop entries the same gaps bring dust and pests. We replace OEM gaskets and sill seals before the leak finds the framing behind the door.
- Rot at the bottom stile. On older San Martin homes with original entry framing, a failing sill or missing flashing channels water straight into the stile. If the fiberglass skin is cracked or the stile is rotting, we’ll tell you to replace the slab or full system rather than keep patching a door that’s already structurally done.
Therma-Tru Service in San Martin: What Local Conditions Mean for Your Equipment
Here’s the part most page templates skip: San Martin has no city hall. Every building permit runs through Santa Clara County, and exterior door or entry-system work has to clear county plan review before inspection. On multi-acre parcels, well and septic approvals can gate the whole project schedule, which means a door install isn’t just a door install. We sequence Therma-Tru threshold and entry work so a final inspection isn’t held up waiting on a stalled site utility sign-off. That’s the kind of thing you only learn by working parcels off Llagas Road and the rural roads south of Therma-Tru in Morgan Hill, not by reading a county website. If the structure makes sense on paper, it’ll hold in the field. If it doesn’t make sense on paper, we fix it before we touch a beam. Same logic applies to a doorway that has to stay square through five months of dry heat and a winter wet cycle.
Therma-Tru Models & Products We Service in San Martin
We install and service the Therma-Tru lines most common on San Martin homes and outbuildings: Smooth-Star fiberglass entry doors, Fiber-Classic fiberglass doors, Classic-Craft American Style collection, and Benchmark fiberglass patio and full-lite door systems. For parts, we use Therma-Tru OEM replacement sills, sweeps, and multi-point hardware where the fit and weather seal depend on exact dimensional match. For cosmetic wear like weatherstrip and fasteners, quality aftermarket parts do the job without inflating the invoice. What’s stocked locally depends on the model, but we’ve usually got common threshold and sweep profiles in the truck, which gets a San Martin door closing clean faster than waiting on a distributor shipment.

AfterTherma-Tru Service Pricing in San Martin
Entry door work here typically runs from a few hundred dollars for a threshold or sweep replacement to $4,500 – $15,000 for a full system with sidelites, depending on size, trim, and the condition of the rough opening. Multi-point lock service and realignment usually lands in the $400 – $1,800 range, same as broader hardware work. A full entry replacement on a San Martin ranch home, where we’re also re-flashing the opening and resetting the jamb, falls in the same $4,500 – $15,000 band as a window replacement package, but you’ll get an exact line-item number before we order anything. A free estimate includes measuring the opening, checking the floor for deflection, and a straight answer on repair versus replace. Call (833) 756-5936 to schedule yours.

FAQs – Therma-Tru Construction in San Martin
Yes, exterior door and entry-system replacements in San Martin require a Santa Clara County building permit, because there’s no city building department to issue one locally. We pull the permit, schedule the inspection, and make sure the work passes the first time. Call (833) 756-5936 and we’ll walk you through the permit path for your specific parcel.
San Martin’s hot, dry summers and long afternoon sun exposure oxidize the factory finish, especially on south- and west-facing Fiber-Classic and Smooth-Star doors with dark colors. It’s not a defect in your door; it’s UV doing what UV does at this latitude. Refinishing is an option when the skin is intact, and replacement makes sense when the texture has gone far enough that the door looks worse than the house behind it.
Usually the frame. San Martin sits on expansive clay soils that swell with winter moisture and settle when the ground dries out. That seasonal movement shifts the jamb, and a multi-point lock has almost no tolerance. We check the opening with a level and measure the reveal at top, bottom, and both sides before touching the hardware. Fixing the alignment properly often means resetting the jamb, not just moving a strike plate.
Yes. We handle Corralitos Therma-Tru service and doors on accessory structures, shops, and barns across San Martin, including west-facing doors on outbuildings that get hammered by afternoon sun and drifting irrigation overspray. These are often the doors with the worst gasket and threshold failures, because nobody notices the leak until the floor inside is stained and the bottom stile is soft.
If the skin is intact and the swelling is limited to the threshold and sweep, a repair makes sense. If the bottom stile has cracked, delaminated, or been trimmed repeatedly to fit a moving opening, replacement is the honest call. We’ll show you the condition and give you numbers for both. Call (833) 756-5936 for an exact quote on your door.
