Therma-Tru Construction in Broadmoor, CA | San Bernardino Contractors
We provide independent Therma-Tru entry door installation and repair across Broadmoor, CA. What makes our work here different is simple: we know Broadmoor’s fog-belt stucco tract homes and the San Mateo County permitting path better than any outside crew. If your Therma-Tru door is dragging, leaking, or rotting at the frame, call us at (855) 473-5620 for a free estimate.
Why Broadmoor Residents Choose Us for Therma-Tru Service
We’ve spent years installing and servicing Therma-Tru Fiber-Classic, Smooth-Star, and Classic-Craft entry systems in Broadmoor’s 1940s and 1950s stucco-over-woodframe homes. That matters because these doors fail differently here than they do inland. Ruben Castillo, our owner, grew up framing and reroofing houses in the Westside neighborhood of San Bernardino, and he learned early that salt air and wind-driven rain don’t forgive shortcuts. “If it’s not built right the first time, you’re just paying for it twice.” We carry OEM Therma-Tru sales & service weatherstripping, sweeps, sills, and hardware, plus quality aftermarket equivalents when OEM parts are discontinued. And because we’re a full-service general contractor, we can rebuild the rough opening, reframe the wall, or pull the county permit in the same visit.

Common Therma-Tru Construction Problems We Solve in Broadmoor
- Rot at the wood sub-sill and jamb legs. Broadmoor’s persistent coastal fog and wind-driven rain off the San Bruno Mountain gap soak the unprotected rough opening around many Therma-Tru units. The original 1950s builders never installed sill pans or proper flashing, so water wicks into the framing and softens the wood around the door long before the fiberglass slab shows any wear. We rebuild the opening correctly, with a real sill pan and flashed jambs.
- Salt-corroded hinges, strike plates, and sill screws. Salt-laden air off the Pacific eats ferrous hardware fast in west- and south-facing Broadmoor entries. We see hinge pins that grind instead of swing and strike plates so pitted the latch won’t seat. We replace with stainless hardware and marine-grade fasteners where the exposure calls for it.
- Worn or shrunken weatherstripping and door sweeps. In these minimally insulated tract homes, the entry door is often the largest visible air and moisture leak. Fog damp wicks past tired seals and drafts follow. We install OEM Therma-Tru replacement weatherstrip and sweeps matched to the specific door series, not a generic roll from the hardware aisle.
- Out-of-square rough openings in settled or unpermitted-conversion walls. Several Broadmoor homes have garage or room conversions done without county sign-off. When the framing underneath was never corrected, a Therma-Tru slab that closed fine at install starts dragging or failing to latch as the opening racks. We square the rough opening before we reset the frame.
- Blistered finish on fiberglass slabs and frames. Constant salt fog and wind-driven rain can blister a factory finish, especially on doors that haven’t been resealed in years. We assess whether the slab and frame are still sound, because a seal-and-hardware refresh often beats a full replacement.
Therma-Tru Service in Broadmoor: What Local Conditions Mean for Your Equipment
Broadmoor is a fully built-out, unincorporated San Mateo County island surrounded by Daly City, and nearly every construction project here is a remodel, addition, or second-story build on a tight mid-century lot. Because the county, not Daly City, issues the permits, any Therma-Tru door replacement or window addition must clear San Mateo County Planning & Building plus separate fire, sewer, and school district reviews that neighboring Daly City Therma-Tru repair jobs never touch. Practically, that means a door replacement you’d pull a same-day permit for in Daly City can take longer here, and it can surface old unpermitted work. We’ve handled enough Broadmoor projects to anticipate that. The energy code checks are county-enforced, so when we replace a Therma-Tru entry door or add windows on a Broadmoor remodel, we don’t just swap the unit, we make sure the rough opening, flashing, and seal meet the county’s current requirements.
Therma-Tru Models & Products We Service in Broadmoor
We install and repair the full Therma-Tru entry door lineup: Fiber-Classic, Smooth-Star, and Classic-Craft series, including systems with sidelites and decorative glass. On the parts side, we stock OEM Therma-Tru replacement weatherstrip, door sweeps, sills, and threshold caps locally so Broadmoor callbacks don’t wait on a freight shipment like a Colma Therma-Tru repair might. When an older Therma-Tru model has discontinued parts, we source quality aftermarket equivalents and tell you plainly what’s OEM and what isn’t. We’re an independent contractor. We’re not authorized, sponsored, or endorsed by Therma-Tru, which means we give you the straight answer on repair versus replacement without a brand script.

FAQs – Therma-Tru Construction in Broadmoor
Why do Therma-Tru entry doors in Broadmoor rot at the frame before the door slab fails? Because salt-laden fog and wind-driven rain off the San Bruno Mountain gap attack the wood sub-sill and jamb legs that Broadmoor’s original 1950s builders left unprotected. The fiberglass slab doesn’t rot, but the rough opening around it does. We rebuild that opening with a sill pan and flashing before we reset the door. Call (855) 473-5620 for a free assessment.
Does replacing an entry door or adding a window in Broadmoor need a San Mateo County permit rather than a Daly City one? Yes. Broadmoor is unincorporated San Mateo County, so the county’s Planning & Building department issues your permits, not Daly City. We pull them for you, and we schedule around the county’s review timeline. For an exact quote on your project, call (855) 473-5620.
How do we handle a Therma-Tru door install when the opening is in an unpermitted Broadmoor garage or room conversion? We check with the county first. If the prior conversion was done without permits, you may need to legalize or demolish the unpermitted work before new plans are approved. We’ve walked Broadmoor homeowners through this process before, and we’ll tell you the truth about what’s required before we start swinging a hammer.
What’s the difference between window replacement and impact window installation for Broadmoor’s wind-driven rain? Window replacement upgrades the glass, frame, and seals to current code and stops drafts and fog damp. Impact window installation goes further, with reinforced glass and frames rated for wind-borne debris and much higher wind pressures than standard units. On Broadmoor’s exposed lots near the fog gap, impact windows buy real protection. Call (855) 473-5620 to talk through which fits your home and budget.
Should we replace our failing Therma-Tru door or just repair the seals and hardware? Depends on the slab and frame. If the fiberglass slab is sound and the opening is still square, an OEM weatherstrip and stainless hardware refresh usually costs far less and buys another decade. If the frame is racked or the sub-sill is rotted, replacing the whole unit in a rebuilt rough opening is the better spend. Estimates are free, so call (855) 473-5620 and we’ll give you a straight answer.
