Therma-Tru Construction in Bloomington, CA | Daly City Construction
We provide independent Therma-Tru door installation and repair across Bloomington, CA. The work here runs through San Bernardino County permitting, not a city building department, which shapes how we handle every door on an older tract home or converted garage. If you own a mid-century stucco house near Valley Boulevard, that distinction matters. Call (866) 505-5254 and we’ll take a look.

Why Bloomington Residents Choose Us for Therma-Tru Service
Daly City Construction is an independent door and remodel contractor. We are not affiliated with Therma-Tru, not sponsored by them, and not authorized by them. We source genuine Therma-Tru doors and replacement parts because they hold up in Inland Empire heat better than most, but we answer to you, not to a manufacturer’s warranty department.
Noel Cabrera grew up in the Westlake district of Daly City, where he spent summers watching his uncle re-frame a garage. He trained in construction technology at City College of San Francisco and has spent years on residential and light commercial work across San Mateo and San Francisco counties. That background matters for Bloomington because the houses here are mostly 1950s to 1970s single-story stucco tracts. The door openings are rarely square. The flashing is often missing. The slab has settled. We expect those problems before we arrive, so the estimate we give you is the one that holds.
We also install Therma-Tru across the rest of our Bloomington service area, including 92316 and surrounding unincorporated pockets.

Common Therma-Tru Construction Problems We Solve in Bloomington
- Sun-driven chalking and clear-coat breakdown on fiberglass skins. Bloomington’s south and west-facing entries take direct Inland Empire sun for eight to ten hours a day. Without a porch overhang, Therma-Tru Smooth-Star and Fiber-Classic skins will chalk, fade, or develop a cloudy clear-coat failure within a few seasons. We re-finish sound slabs and replace skins when the damage is too deep.
- Out-of-square binding from settled openings. Many Bloomington homes are original mid-century builds with garage-conversion openings added decades later. The ground has moved since. When a Therma-Tru door binds at the latch or the multi-point lock stops throwing cleanly, the problem is usually the opening, not the slab.
- Dried and cracked weatherstripping from Santa Ana grit. Santa Ana winds here push dust and fine grit into the jamb, the hinge side, and the sweep. We replace dried Therma-Tru weatherstrip kits and door sweeps with genuine parts before they chew up the throat of the door.
- Sill and threshold rot from poorly flashed additions. Bloomington’s winter rains expose what previous remodels did wrong. When a patio or room addition was flashed improperly, water pools at the slab edge and rots the sill or rusts the threshold under a perfectly good Therma-Tru slab. We rebuild the rough opening and re-flash it properly.
- Reused exterior doorways on garage conversions failing under county inspection. When a garage becomes living space, the original exterior doorway often becomes the new front door. If it was set without a sill pan and proper flashing, it will drag, leak, and eventually fail. We fix that before the county inspector sees it.
Therma-Tru Service in Bloomington: What Local Conditions Mean for Your Equipment
Bloomington is unincorporated San Bernardino County. That is not a technicality. It changes the permit path, the inspection sequence, and the level of documentation we keep on every exterior door job, especially on garage conversions and backyard ADUs. A homeowner in Colton or Fontana can file a simple city permit. Here, we work with the county, and the county checks things city inspectors sometimes miss: setbacks, flashing detail, egress, and structural openings.
What that means for a Therma-Tru owner is concrete. If your house near Valley Boulevard or Jurupa is a converted garage with a reused exterior opening, that door is likely not flashed the way county code now requires. The jamb may be out of square. The bottom rail may have rotted because no sill pan was installed. We routinely find Therma-Tru Fibre-Classic doors set in rough openings that never saw a flashing tape, let alone a sill pan. The door drags in summer, leaks in winter, and the county will flag it if the conversion ever gets pulled into inspection.
We see the same pattern on the small-lot stucco homes along the I-10 corridor: older tract houses, attached garages, parking yards and commercial spaces mixed on the same street, and we also handle Therma-Tru repair in Rialto. Door work here is rarely a simple swap. It is usually a re-flash, a re-square, and a documented fix. That is exactly the work we do for Bloomington homeowners.
Therma-Tru Models & Products We Service in Bloomington
We service the full Therma-Tru residential line that shows up on Bloomington homes. That includes Therma-Tru Smooth-Star fiberglass entry doors, Fiber-Classic and Classic-Craft entry systems, fiberglass patio and sliding doors, and sidelite and decorative-glass entry assemblies.
Our parts policy is simple. If the slab and frame are sound, we use genuine Therma-Tru replacement hinges, sweeps, weatherstrip kits, and sidelite glazing. If the skin is delaminated, the frame is rotted, or the opening is too far out of square, we move to a full prehung unit. We re-hang and re-seal a good Therma-Tru door before we sell a replacement. Good door work starts with honesty about whether the door is the problem.

FAQs – Therma-Tru Construction in Bloomington
Almost always the opening. Bloomington’s older slab-on-grade homes settle, and garage-conversion openings are rarely framed square. The Therma-Tru slab is probably fine. The fix is re-squaring the jamb, re-hanging the door, and re-flashing the opening. Call (866) 505-5254 and we’ll tell you for sure.
Yes. Because Bloomington is unincorporated San Bernardino County, exterior door replacement on an ADU or garage conversion is typically reviewed and inspected by the county, not a city building department, unlike Therma-Tru repair in Pedley. We document the opening, flashing, and hardware for inspection. That documentation has saved homeowners from failed inspections more than once.
Direct Inland Empire sun, days on end, with no porch overhang. Bloomington’s south and west elevations absorb heat that breaks down the clear-coat on Smooth-Star and Fiber-Classic skins. We can re-finish a sound slab or replace the skin if the substrate is cooked through.
Usually yes. We install genuine Therma-Tru replacement weatherstrip kits and door sweeps that seal the jamb and hinge side. Grit buildup will destroy the sweep over time, so we check it during every Bloomington door call. If the slab itself is still sound, there is no reason to replace it.
The flashing. Previous remodels often flash the rough opening poorly, so water pools at the slab edge and works under the threshold. We cut back the affected area, rebuild the rough opening, install proper flashing and a sill pan, and reseal the Therma-Tru unit. Call (866) 505-5254 for an exact diagnosis.
