Therma-Tru Construction in Upland, CA | San Bruno Construction
We provide independent Therma-Tru door installation, repair, and replacement across Upland, from the citrus-era ranch homes on the flatlands to the foothill properties in 91784. What makes our Therma-Tru work different here is simple: we deal with the split between standard door service and Chapter 7A fire-zone compliance every single week. One contractor coordinating the whole job means the door, the framing, the flashing, and the permit all line up. Call (866) 472-1908 for a free estimate on any Therma-Tru project in Upland.
Why Upland Residents Choose Us for Therma-Tru Service
We’ve installed and serviced Therma-Tru door systems across Upland’s older ranch and foothill homes for years, so we know how their fiberglass slabs, rot-resistant frames, and multipoint hardware behave under real Inland Empire sun and Santa Ana wind loads. As an independent contractor, we source Therma-Tru components directly and install them to manufacturer spec. We are not authorized, sponsored, or endorsed by Therma-Tru, and we’re upfront about that. What we bring instead is two decades of residential construction experience led by Noel Carvalho, who grew up off El Camino Real and trained in construction technology at Skyline College, where he learned to read plans and understand load paths before a single tool comes out of the truck. For Upland homeowners, that means your Therma-Tru door gets installed by someone who thinks about how the whole house works, not just the slab hanging in the opening.
We stock genuine Therma-Tru replacement parts for faster turnaround on Upland service calls: sills, sweeps, hinges, glass frames, and multipoint hardware. When a door is sound but weathered, we refinish and re-hang it. When the slab or bottom rail is rotted, we tell you straight and recommend full replacement rather than chasing rot with patchwork.

Common Therma-Tru Construction Problems We Solve in Upland
Here’s what we see most often on Therma-Tru doors in Upland, and why the local conditions matter:
- Sun-chalked and faded fiberglass skins. South- and west-facing entries in Upland take brutal summer UV for months on end. Classic-Craft and Smooth-Star doors in darker paint colors chalk, fade, and hairline-crack after years of dry heat. We refinish the salvageable ones and replace the slabs that have gone too far.
- Santa Ana wind damage to hinges and latches. Wind-driven grit and debris off the San Gabriels work loose hinges, strike plates, and adjustable sills on Classic-Craft and Smooth-Star doors. The result is a drafty door that won’t latch cleanly. We re-align, tighten, and replace worn multipoint hardware with genuine Therma-Tru parts.
- Bottom rail and jamb rot from winter rain. Older Therma-Tru units on Upland ranch homes wick moisture during the rainy season where thresholds weren’t flashed correctly. You’ll see soft wood rot and paint blistering at the bottom corners. This is almost always a replacement job, because patchwork on a rotted bottom rail is money thrown away.
- Delaminated Fiber-Classic door skins. Foil and painted door skins bubble and peel where heat buildup behind a storm door traps solar gain on west-facing foothill elevations. We see this a lot in the 91784 ZIP, where afternoon sun pounds the mountainside homes.
- Drafty, misaligned adjustable sills. The adjustable sill on a Therma-Tru door is a precision piece. Years of thermal cycling in Upland’s hot summers and cool winter nights cause them to warp or seize. We replace them with genuine Therma-Tru sills and reset the door so it seals tight.
Therma-Tru Service in Upland: What Local Conditions Mean for Your Equipment
Upland’s 91784 foothill homes fall in designated high fire severity zones, so Therma-Tru exterior doors on those properties get pulled into Chapter 7A wildland-urban interface review. That means exterior door assemblies and frames must meet ember- and fire-resistance requirements that flatland Therma-Tru installs in neighboring cities never have to satisfy. A homeowner off Euclid Avenue replacing a worn entry door in the flatlands can pick any Therma-Tru slab they like and we hang it the same week. The same job up on a hillside tract above Mountain Avenue needs a door assembly that complies with Chapter 7A material and vent requirements, and the inspector will check. We coordinate that end to end: the door selection, the frame, the flashing, and the permit paperwork that proves the assembly meets the fire-zone standard. Good construction doesn’t announce itself. It just works, year after year, and it passes inspection when the city comes to look.
We saw exactly this on a citrus-era ranch home off Mountain Avenue near the foothills. The original Classic-Craft fiberglass entry had a sun-chalked slab and a bottom rail rotted from winter rain wicking past a poorly flashed threshold. We set a new Therma-Tru slab in a properly flashed frame with a new adjustable sill and multipoint hardware, then confirmed the assembly met the property’s Chapter 7A exterior-door requirements before closing out. That’s the difference between a door guy and a general contractor who understands what Upland’s building department actually checks.
Therma-Tru Models & Products We Service in Upland
We work on the full Therma-Tru residential lineup, from the Classic-Craft fiberglass entry series to Smooth-Star doors and the Fiber-Classic line. That includes door glass and sidelite options, decorative caming lines, and the multipoint hardware on each system. Our Therma-Tru sales & service approach is straightforward: use genuine Therma-Tru replacement parts because aftermarket lookalikes fit poorly and fail faster in this climate. We keep common sills, sweeps, and hinges in stock for quick Upland turnaround, and anything unusual we order directly. When a door is sound but weathered, we refinish and re-hang it. When the slab or bottom rail is rotted, we recommend full replacement rather than chasing rot with patchwork.

A door replacement on its own runs less than a full addition, but the driver is always the opening: is the frame sound, does the flashing need rework, is the property in a Chapter 7A fire zone where the assembly spec changes.

FAQs – Therma-Tru Construction in Upland
Do you install Therma-Tru doors as part of an ADU or home addition in Upland?
Yes, we install Therma-Tru exterior doors as part of ADU construction and home additions throughout Upland, and we coordinate the door with the entire project, so the framing, flashing, and fire-zone compliance on 91784 foothill properties are handled under one contract. Call (866) 472-1908 to talk through your ADU door package. Estimates are free.
Are you an authorized Therma-Tru dealer?
No, San Bruno Construction is an independent contractor. We source Therma-Tru components directly and install them to manufacturer spec. We are not authorized, sponsored, or endorsed by Therma-Tru. What you get is a general contractor who has worked with these door systems across Upland for years and can coordinate the door with the rest of the build.
Do you use genuine Therma-Tru parts for Upland repairs?
Yes. We use genuine Therma-Tru replacement parts: sills, sweeps, hinges, glass frames, and multipoint hardware. Aftermarket lookalikes fit poorly and fail faster in Upland’s sun and Santa Ana wind conditions, so we won’t install them.
How long does Therma-Tru door service take in Upland?
Most door replacements and refinishing jobs in Upland are completed in one to three days, depending on whether the frame needs rework or a foothill property requires Chapter 7A assembly documentation. A simple slab swap on a flatland ranch home can often be done in a day. Call (866) 472-1908 for a timeline on your specific job.
How much does a Therma-Tru door replacement cost in Upland?
A door replacement on its own is priced by the opening, not a flat fee. The cost depends on whether the frame is sound, whether flashing needs rework, and whether the property falls in a Chapter 7A fire zone in 91784. A full ADU construction that includes Therma-Tru doors runs $90,000 to $220,000, while a home addition with doors runs $45,000 to $130,000. Call (866) 472-1908 for an exact quote. Estimates are free.
