Therma-Tru Construction in Lompico, CA | Milpitas Construction
We install, repair, and replace Therma-Tru door systems throughout Lompico, and we’ve been doing it long enough to know exactly what this canyon does to a door. Milpitas Construction is an independent construction firm, not a factory-authorized dealer. What that means for you is honest repair-versus-replace guidance, OEM parts when they matter, and a crew that understands how fog drip, steep lots, and CalFire rules shape every entry and patio door here. Call (877) 752-4194 for a free estimate.
Why Lompico Residents Choose Us for Therma-Tru Service
We spec materials by name, so you know exactly what’s going into your home. When we replace a Therma-Tru door in Lompico, we’re matching the model to the microclimate, not just pulling something off the shelf. Ken Stafford grew up in the South Bay and has spent two-plus decades building and remodeling across the region’s soil shifts and seismic quirks. He knows a swollen stile from a framing problem the minute he sees it.
Our crews work on the Therma-Tru lines that show up again and again in these mountain homes: Fiber-Classic, Smooth-Star, Classic-Craft, and the patio door systems with Low-E glass. We carry OEM hinges, sweeps, and weatherstripping in our trucks for faster Lompico turnaround, and we’re honest when a door is worth repairing versus when you’re throwing good money after bad. For broader work beyond doors, see our Therma-Tru sales & service page.

Common Therma-Tru Construction Problems We Solve in Lompico
Here’s what we see most weeks on doors in this canyon:
- Chalky, cracked fiberglass skins. South- and west-facing entries in Lompico take intense UV at elevation, and darker finishes on older Fiber-Classic doors are the first to go. Hairline cracks let moisture behind the skin. Sometimes we can refinish; other times the door slab is done.
- Swollen, delaminating wood stiles and rails. Fog drip is relentless here. Older Therma-Tru doors with the original factory stain absorb that moisture along the edges, and the stiles swell until the door binds against the frame. If the frame is solid, we’ll replace the slab and seal it properly.
- Rusting steel door bottoms. Splashback from decks and stairs stays wet in Lompico’s shaded lots. Steel Therma-Tru entry doors rust at the bottom edge and around hardware cutouts faster than most homeowners expect.
- Torn, compressed weatherstripping on patio doors. Redwood debris and moss collect along the tracks here. Once the sweep or weatherstripping tears, drafts and water intrusion follow. We replace with OEM Therma-Tru seals so the fit is exact.
- Failed insulated glass in patio doors. The fog-and-sun cycle is hard on Low-E units in Lompico. When the seal fails and condensation shows between panes, we source OEM replacement glass rather than retrofitting something that doesn’t fit the frame.
Therma-Tru Service in Lompico: What Local Conditions Mean for Your Equipment
Here’s something most flatland door companies don’t plan for: Lompico’s narrow private roads and limited turnarounds mean a standard 26-foot delivery truck cannot navigate many driveways off West Drive or Lompico Road. We schedule Therma-Tru door replacements with smaller delivery vehicles and stage materials on site ahead of the crew. That changes lead time, delivery cost, and sometimes which door config we recommend. A pre-hung unit that has to be manhandled 200 feet up a steep switchback driveway is a different job than a slab swap. We plan for that before the first nail comes out.
Beyond access, the canyon’s winter rain and fog drip shape every install. We flash above the header, protect the threshold from runoff, and spec weatherstripping that closes tight. Summer brings a different problem: wildfire. Door and window material classes matter for defensible-space compliance here, and we factor that into material selection. This is the kind of ground-level knowledge you only get from working these roads, not from a call center. That’s the difference when you hire a team that serves Lompico service area homeowners regularly.
Therma-Tru Models & Products We Service in Lompico
We service the full residential Therma-Tru lineup you’re likely to find in Lompico’s older cabins and newer custom builds:
- Fiber-Classic entry doors – the original fiberglass workhorse, common on mid-century and 1970s mountain homes.
- Smooth-Star fiberglass doors – a clean, dent-resistant option we often recommend for replacement where canyon moisture has killed the old door.
- Classic-Craft door series – higher-end wood-grain doors, frequently specified on newer customs and additions.
- Patio door systems with Low-E glass – including sliding and hinged patio systems that take a beating from fog and debris.
Our parts approach is practical. When hinges, glass, or weatherstripping need replacing, we use Therma-Tru OEM parts so the fit and warranty stay intact. When a homeowner wants hardware from the 1970s cabin they love, and OEM is long discontinued, we know which aftermarket suppliers carry quality vintage-style hardware that doesn’t look like a landlord special.

| Roof Repair | $400 – $1,800 |
| Home Addition | $45,000 – $130,000 |
Those are project-level prices, not door-only numbers, because most Lompico homeowners need surrounding work done at the same time: flashing, trim matching, threshold protection, sometimes a roof diverter above the entry. Your free estimate includes a line-item breakdown so you know the door, the labor, and any access staging costs separately. No change orders invented after you sign. Call (877) 752-4194 and we’ll walk the site with you.

FAQs – Therma-Tru Construction in Lompico
Defensible-space rules focus mostly on vegetation, but roof class, eave construction, and exterior material choices come into play in the WUI zone. We recommend fiberglass or steel Therma-Tru doors over wood-edged models for ember resistance, and we can advise on weatherstripping that keeps embers from blowing into gaps. We offer similar guidance for Therma-Tru in Brookdale. Call (877) 752-4194 if you want a straight answer for your specific lot.
Not necessarily. If the slab and frame are structurally sound, a proper refinish or a factory-finished replacement slab can solve the problem for a lot less money. Chalking alone doesn’t mean the door is failing. We’ll inspect the stiles, the sweep, and the glass before recommending anything. Estimates are free.
We can. Lompico has a lot of original redwood trim worth keeping, and our finish carpenters can mill or source matching redwood when the existing trim is too far gone to reuse. We’ve done it on cabin replacements throughout the canyon, including a 1970s redwood place off Lompico Road where we kept the trim character intact while swapping the slab. We also handle Therma-Tru repair in Felton.
Custom Classic-Craft and Smooth-Star orders typically run three to five weeks from order to delivery, but Lompico’s access constraints can add time if we need a smaller delivery vehicle or staged unloading. We’ll give you a realistic date when you order, not a promise we can’t keep. Call (877) 752-4194 for a current lead time quote.
A straight door replacement in the same rough opening usually does not. If we’re moving the opening, widening it, or doing structural work around the frame, you’ll likely need county sign-off. We pull permits when they’re required and get inspections passed. That’s part of the job, not an add-on.
