Therma-Tru Construction in Hillsborough, CA | Framework Contractors
We’re Framework Contractors, and we provide independent Hillsborough General Contractor services including Therma-Tru installation, repair, and retrofit across estate-scale homes. The thing that sets our Therma-Tru work here apart is that we don’t treat a door swap as a door swap. On Hillsborough’s wooded, slope-cut lots, the door spec gets settled alongside the arborist plan, the drainage layout, and the town’s design-review rules, not after them. Call (844) 681-3590 for a free estimate.
Why Hillsborough Residents Choose Us for Therma-Tru Service
We’ve spent years installing and retrofitting Therma-Tru entry, patio, and sidelite systems into Hillsborough’s specific housing stock: early-to-mid-20th-century estates, ranch-style homes, and newer custom builds on lots that often run half an acre to over an acre. We know how Fiber-Classic slabs, rot-resistant frames, and multipoint hardware actually behave when they’re mounted on a hillside grade with clay soil, heavy canopy, and a design-review board watching every change. As an independent contractor, we work to the door’s real installation tolerances and the town’s requirements, not to a dealer’s sales script.
Noel Carbajal, our owner, grew up learning framing and finish work the hard way, on real job sites before he had a driver’s license. He’s spent close to three decades building and remodeling, and that experience shows in how we approach a Therma-Tru install on a Hillsborough estate: measure the rough opening twice, check the slope away from the threshold, and spec the door for the site, not the brochure. We carry genuine Therma-Tru sills, sweeps, weatherstrip, and multipoint hardware for the doors worth keeping, and quality aftermarket glazing and finish systems where the OEM part is out of production. You’ll get an honest read on whether a slab and frame are still sound enough to repair or whether a full unit replacement is the cheaper long-term answer.

Common Therma-Tru Construction Problems We Solve in Hillsborough
- Chalked and dulled finishes on west- and south-facing entries. Hillsborough’s long dry summers mean a Therma-Tru Fiber-Classic entry with full sun exposure and no oak shade will lose its finish faster than the same door on a shaded lot. We strip, prep, and refinish with UV-stable systems, or re-spec the door finish if it’s beyond saving.
- Sill and threshold rot from winter runoff. Wet winters on clay soils, combined with hillside grades that shed toward the stoop, pool water against door sills. In Hillsborough we regularly see sill rot where the deck edge or stoop pitches toward the opening. We rebuild the threshold and sub-sill with proper slope-away flashing, then reset the unit.
- Weatherstrip and sweep failure under heavy canopy. Grit, leaf litter, and redwood or oak debris get trapped in jamb tracks on heavily treed lots. That debris grinds down weatherstrip and sweeps years before their time. We clean the track, replace the seals, and where the canopy is the real problem, we recommend a sweep profile that sheds debris better.
- Out-of-square slabs that drag after framing movement. Older Hillsborough estate additions settle. When a Therma-Tru door suddenly sticks, it’s often not the door; it’s the rough opening that shifted. We re-shim, re-align, and where needed, re-hang the slab so it clears properly without planing down a door that was never the problem.
- Threshold leaks at patio and French door systems. Hillsborough’s slope-cut lots put patio doors low in the grade, where winter rain runs toward the opening. We address the flashing, the sill pan, and the drainage path, not just the gasket, so the fix lasts past the next storm season.
Therma-Tru Service in Hillsborough: What Local Conditions Mean for Your Equipment
Here’s what makes Therma-Tru work in Hillsborough genuinely different from anywhere else in the Bay Area. Hillsborough is estate-zoned, with almost no commercial base and lots frequently running 0.5 to 1+ acre. A new or enlarged Therma-Tru entry or patio door here is rarely a simple one-for-one swap. It’s usually part of a design-review and tree-protection package, because a mature oak or redwood on the lot can dictate where the opening, stoop, and even driveway access land. That means the door spec gets settled alongside the arborist plan, not after it. A homeowner on a street like Ralston Avenue or in the wooded canyons off Chateau Drive can’t just widen a rough opening and call it done. The town’s design-review and tree-protection rules run first, and the door follows. We’ve worked inside that process long enough to know how to phase the door work so it doesn’t stall a project or trip a violation. Build it right the first time, the second time costs twice as much and nobody’s happy.
Therma-Tru Models & Products We Service in Hillsborough
We service the full residential Therma-Tru line that shows up in Hillsborough homes: Fiber-Classic and Fiber-Classic Oak entry doors, Smooth-Star fiberglass entry doors, Therma-Tru patio and French door systems with matching sidelites, and the rot-resistant frames and adjustable sills that come with them. Our parts approach is simple. Where the door is worth keeping, we use genuine Therma-Tru sills, sweeps, weatherstrip, and multipoint hardware. Where an OEM part is out of production, we use quality aftermarket glazing and finish systems instead of telling you to replace a door that doesn’t need replacing. We keep common Hillsborough-specific parts on hand so most entry-door repairs on this side of 280 don’t wait on a distributor. For broader work like a full kitchen remodel or bathroom remodel that includes a Therma-Tru exterior door change, we fold the door into the same contract and the same crew, which keeps the schedule and the accountability in one place. We’re an independent Therma-Tru service provider, not a manufacturer-affiliated or authorized dealer. See our Therma-Tru sales & service page for the full scope of what we handle.

AfterTherma-Tru Service Pricing in Hillsborough
Therma-Tru door work in Hillsborough prices by the same three drivers every time: condition of the existing rough opening, whether the surrounding stoop or deck is shedding water correctly, and whether the door is part of a larger project that already has design-review conditions attached. A simple slab re-hang with new weatherstrip runs at the low end. A full entry replacement with sill rebuild, new flashing, and sidelite work lands higher. Here are the ranges we work within:
| Service | Typical Range |
|---|---|
| Window Replacement | $4500 – $15000 |
| Kitchen Remodel | $14000 – $45000 |
| Bathroom Remodel | $9000 – $28000 |

FAQs – Therma-Tru Construction in Hillsborough
Generally no. Hillsborough’s estate zoning means any change to an exterior opening, especially an enlargement, usually triggers design-review and often tree-protection requirements. A like-for-like swap in the same rough opening may not. We’ll tell you which path your project falls into before any work starts. Call (844) 681-3590 and we’ll walk the site with you.
Hillsborough’s clay soils expand when wet, and older estate additions move with them. The rough opening shifts slightly, the slab binds, and the door drags. It’s rarely the door. We re-shim and re-align the unit to the current opening, and where the movement is structural, we’ll point you to the framing fix. Call (844) 681-3590 for an exact diagnosis.
Almost never. West- and south-facing fiberglass doors in Hillsborough take full summer sun with no oak shade, and the factory finish chalks. The door’s structural integrity is usually fine. We strip, prep, and refinish with a UV-stable system, or re-spec the finish if the door’s seen years of exposure. Call (844) 681-3590 and we’ll tell you which one applies.
Yes, and more than most people expect. A protected tree can dictate where the opening, stoop, and driveway access land, so the door spec follows the arborist plan. We’ve worked that process on enough Hillsborough lots to phase the door work so it doesn’t stall the project. Call (844) 681-3590 if you’re planning a door change on a treed lot.
If the rough opening stays the same and nothing structural changes, it’s often treated as like-for-like. If you’re widening the opening, changing the header, or touching the exterior envelope, it’s a permit matter, and on a Hillsborough estate it usually runs through design review. We’ll tell you which category yours falls into before you spend a dollar. Call (844) 681-3590 for a straight answer.
