Therma-Tru Construction in San Antonio Heights, CA | San Bruno Construction
We provide independent Therma-Tru door installation, repair, and replacement across San Antonio Heights, zip code 91784. The one thing that sets our Therma-Tru work here apart: we know how these doors fail on steep, hillside lots in a high fire-hazard zone, and we plan every installation around drainage, grade, and San Bernardino County permitting before the first hole is cut. San Bruno Construction is not a Therma-Tru dealer or manufacturer-authorized shop, and we don’t pretend to be. We’re a full-scope general contractor in San Antonio Heights that has installed and serviced Fiber-Classic, Smooth-Star, Pulse, and Professionals Series doors across the San Bernardino foothills for over a decade. Call (866) 472-1908 for a free estimate on any Therma-Tru job in San Antonio Heights.
Why San Antonio Heights Residents Choose Us for Therma-Tru Service
Most door companies send a tech with a truck full of generic parts and a flat-rate book. That doesn’t work in San Antonio Heights, where a door that binds in August might be a foundation issue by December. Our crew, led by owner Noel Carvalho, approaches every Therma-Tru job as a construction problem first and a door problem second. That means we check the slab, the drainage path, the rough opening, and the county’s Chapter 7A requirements before we quote a repair. We source genuine Therma-Tru OEM hinges, lock kits, sweeps, and glass cassettes whenever possible, because aftermarket parts rarely line up on a door that’s been baking in foothill sun for fifteen years. And because San Bruno Construction coordinates every trade under one contract, a Therma-Tru door replacement that reveals a shifting retaining wall doesn’t strand you with three separate vendors and a phone-tree headache. Therma-Tru sales & service is one part of what we do, but it’s a part we take seriously.

Common Therma-Tru Construction Problems We Solve in San Antonio Heights
- Hairline cracks at the lock bore and hinge stiles. Fiber-Classic and Smooth-Star fiberglass skins expand and contract through thermal cycling, and San Antonio Heights gets exactly that: hot valley afternoons followed by cool mountain air dropping in after sunset. West-facing entries off Euclid and other exposed slopes take the worst of it. Small cracks can sometimes be stabilized; deep spidering means a new slab.
- Wood-edge rot on older fiberglass doors. When the factory finish wears thin, water gets into the wood edge core along the bottom rail and sidelite jambs. On hillside homes where wind-driven rain hits door bottoms during winter downpours, this rot moves fast. We see it constantly on original mid-century installs.
- Failed weatherstripping and door sweeps on Pulse and Professionals Series doors. In a wildland-urban interface fire zone, this isn’t a comfort issue. It’s an ember intrusion issue. Gaps around the door perimeter let smoke and embers work their way in during wildfire season, which is a serious concern for every home in this high fire-hazard-severity area.
- Warped or sticking slabs on Smooth-Star patio doors. On sloped, terraced lots, the deck or patio moves independently of the house. A patio door that drags or won’t latch is often a sign that an unpermitted retaining wall is pushing the frame out of square. We trace the frame movement back to the cause before recommending a solution.
- Ignition-resistant compliance gaps on older doors. Many San Antonio Heights homes still have original entry doors that would never pass today’s Chapter 7A standards. When we replace them, we specify Therma-Tru assemblies with fire-rated components, and we pull the San Bernardino County permit to document the upgrade.
Therma-Tru Service in San Antonio Heights: What Local Conditions Mean for Your Door
Here’s the fact that changes everything about door work in San Antonio Heights: because this community is unincorporated, any exterior door replacement that alters the building envelope must be permitted through San Bernardino County, not a city hall. That’s a step Upland Therma-Tru service contractors working a few hundred feet down the hill never have to take. And under Chapter 7A of the California Building Code, exterior openings in this high fire-hazard zone must meet ignition-resistant standards. A Therma-Tru Fiber-Classic door with the right glazing and weatherstripping can meet those standards. A 1972 wood door with a rusted threshold cannot. We handle the county paperwork, coordinate the inspection, and make sure the door assembly we install actually passes. On a steep lot off Crestview Drive, we replaced a rotting Fiber-Classic entry door and sidelites on a 1960s custom home. The frame had shifted because an old patio slab drained toward the house. We corrected the grade, installed a new Smooth-Star door with a fire-rated assembly, finished with OEM weatherstripping, and pulled the required county permit to close it out. That’s the difference between a door swap and a door job done for this hillside.
Therma-Tru Models & Products We Service in San Antonio Heights
We work on the full residential Therma-Tru lineup: Fiber-Classic entry systems, Smooth-Star doors and patio sliders, Pulse series doors with integrated lighting and locking, and Professionals Series doors built for heavier use. On most calls in San Antonio Heights, we can source OEM hinges, lock kits, sweeps, and glass cassettes within a few days from regional suppliers, which keeps turnaround tight for a hillside community without local door-parts counters. For doors that need full slab or frame replacement, we bring the new unit up from our suppliers and stage it on-site before tear-out to keep your opening exposed for as little time as possible. If you’re not sure which model you have, our team can identify it from door edge markings and hinge patterns.

FAQs – Therma-Tru Construction in San Antonio Heights
Yes, in most cases. Because San Antonio Heights is unincorporated, exterior door replacements go through San Bernardino County’s building department, and under Chapter 7A, the new assembly must meet ignition-resistant requirements. We pull the permit and coordinate inspection as part of the project. Call (866) 472-1908 if you want us to check your specific door’s compliance before you replace it.
It depends on how deep the cracks run and whether the fiberglass skin has separated from the core. Hairline surface cracks at the lock bore can sometimes be stabilized, but if the lock side flexes when the deadbolt throws, the structural integrity is gone and a new slab is the safer call. We’ll assess it on-site and give you an honest repair-versus-replace recommendation. Estimates are free.
Check the fire rating stamped or labeled on the door edge, and inspect the weatherstripping and sweep for full perimeter contact. If your door predates Chapter 7A or shows gaps where embers could enter, it likely won’t pass a county inspection for exterior openings in San Antonio Heights. We can inspect it and tell you exactly where you stand. Call (866) 472-1908 to set up an assessment.
Because the frame is moving. On sloped, terraced lots in San Antonio Heights, clay soil expands with winter moisture and contracts through dry summers, which shifts decks, patios, and door frames out of alignment. The fix usually isn’t just hinge adjustment; it’s correcting the drainage or retaining wall that’s causing the movement. We’ll trace it to the source before recommending a repair or reset.
Yes. Therma-Tru publishes exact color codes and finish specs, and we order replacement slabs or touch-up kits matched to the original factory color. For doors that have faded over years of foothill UV, we’ll bring finish samples to your home so the match works in your light, not the showroom’s. Call (866) 472-1908 to schedule a color match and free estimate.
