Therma-Tru Construction in San Bernardino, CA | San Mateo Construction
We’re San Mateo Construction, an independent Therma-Tru service in Muscoy and across San Bernardino. We install, re-hang, re-flash, and repair Therma-Tru entry, patio, and sidelite systems, and we do it without manufacturer authorization. What makes our work different here is that we account for the Santa Ana winds, the unbolted mid-century framing, and the wildfire-adjacent detailing that generic installers miss. If your Therma-Tru door sticks, leaks, or sun-chalks in San Bernardino, call (855) 901-7266 for a straight answer and a free estimate.
Why San Bernardino Residents Choose Us for Therma-Tru Service
We’ve worked Therma-Tru in Highland and across San Bernardino long enough to know how they fail here. Not how they fail in a brochure or a training video. How they fail when a Santa Ana wind event pushes dust and grit under the sweep for three days straight. How they fail on a west-facing slab that’s baked through 110° summers with no shade. Noel Carrington, our owner, has been in construction for decades and runs our Therma-Tru work with the same approach he brings to every project: tell me what you actually need, and we’ll figure out the right way to build it. We don’t sell you a new door when a re-hang and reseal fixes the problem. We don’t put aftermarket hinges into a frame that came with Therma-Tru OEM hardware. And we don’t leave a San Bernardino job without checking the rough opening for shear and anchor issues, because around here, that’s usually the real culprit.
We carry Therma-Tru OEM hinges, multi-point hardware, weatherstrip, sweeps, and matching sidelite components. If a wear item is unavailable from Therma-Tru or the cost doesn’t make sense for the door’s age, we’ll tell you that too, and we’ll source a quality aftermarket alternative rather than leaving you hanging. Our Therma-Tru sales & service work covers the full San Bernardino service area, from the mid-century tracts to the foothill properties that sit closer to the WUI line.

Common Therma-Tru Construction Problems We Solve in San Bernardino
- Sill and bottom-rail failure from Santa Ana grit. San Bernardino’s fall wind events push fine dust and sand against entry doors for hours at a stretch. That grit packs into the threshold sweep, wears the weatherseal down, and lets wind-driven moisture work past the pan flashing into the bottom rail. We’ve pulled Fiber-Classic doors where the bottom rail felt like a sponge. The fix is a new OEM sweep, a properly shimmed and flashed threshold, and sometimes a bottom-rail repair or slab replacement.
- Sun-chalked finish and lifting edge seal on west- and south-facing slabs. The inland UV here is brutal. Painted fiberglass surfaces chalk and fade, and the edge seal lifts as heat cycling breaks the bond. Once that edge seal goes, moisture wicks into the slab edges and the door starts to delaminate. We refinish, reseal, and when the slab is too far gone, we replace it. But we check first, because refinishing a sound Fiber-Classic slab is a fraction of the cost of a new door.
- Racked frames and sticking locks on unbolted 1950s stucco homes. San Bernardino’s older housing stock was framed before seismic anchoring was standard. No shear bracing, no anchor bolts. Seasonal movement and micro-settling twist the rough opening out of square, and suddenly the deadbolt won’t throw and the door drags on the latch side. You can’t fix that with a chisel. The opening needs to be re-squared, and often the sill plate needs bolting before the Therma-Tru frame goes back in.
- Ember and ignition exposure at the head flashing, jamb, and sweep in WUI-adjacent properties. Properties near the wildland-urban interface around San Bernardino need exterior openings detailed for wildfire hardening. If the seal was never upgraded, embers and smoke can find their way past the head flashing and jamb. We re-detail the opening with fire-resistant materials and proper seals so the exterior door does its job in a wind-driven ember event.
- Loose or failing sidelite assemblies. Sidelites take the same wind, grit, and sun as the main slab, but they’re often forgotten until they leak or fog. We re-seat, re-flash, and reseal sidelite units, and when the glass is blown or the frame is compromised, we replace with matching Therma-Tru components so the whole assembly keeps its intended look.
Therma-Tru Service in San Bernardino: What Local Conditions Mean for Your Equipment
Here’s the thing most Therma-Tru pages won’t tell you. In San Bernardino’s older North Park and Westside neighborhoods, the original 1950s stucco homes were built without shear bracing or foundation anchor bolts. That’s a seismic issue on paper, but it’s also a door issue in practice. Any project that changes an exterior door opening or adds a second story almost always requires a seismic retrofit before the new Therma-Tru frame can be set into code-compliant framing. We’re talking plywood shear walls, foundation bolting, and re-squaring the rough opening. Skip that step and your new Therma-Tru repair in Loma Linda or Classic-Craft door will rack and bind within a couple of seasons, no matter how good the installation looks on day one. On a 1954 stucco ranch off the Westside, our crew pulled a Fiber-Classic entry whose bottom rail had softened from years of Santa Ana grit grinding past the sweep. Because the original opening had no anchor bolts or shear bracing, we bolted the sill plate and added plywood shear before reframing the rough opening to a prehung Smooth-Star unit with a new pan flashing and OEM sweep. The door now latches true and the frame no longer racks with the seasons.
Therma-Tru Models & Products We Service in San Bernardino
We service the full Therma-Tru residential line: Fiber-Classic entry doors, Smooth-Star fiberglass doors, Classic-Craft premium slabs, and patio and sidelite systems. If the fiberglass slab and frame are structurally sound, we re-hang, re-flash, and reseal rather than sell a replacement. Replacement is for delaminated slabs, rotten bottom rails, or openings that need structural reframing. We keep Therma-Tru OEM hinges, multi-point hardware, weatherstrip, sweeps, and matching sidelite components in our San Bernardino work flow so we’re not waiting on a parts order for common fixes. For high-end Classic-Craft units, we match the finish and grain so a repaired door doesn’t look patched.

AfterTherma-Tru Service Pricing in San Bernardino
Therma-Tru service costs depend on whether we’re repairing, re-hanging, or replacing, and on what the rough opening needs. San Bernardino’s unbolted mid-century framing sometimes adds structural work that a straightforward re-hang wouldn’t require in a newer tract. Here’s the pricing for the exterior door-adjacent work we do most often alongside Therma-Tru service:
| Service | Price Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Home Addition | $45,000 – $130,000 |
A free estimate includes an on-site look at the door, the rough opening, and the surrounding stucco and flashing. We give you a written line-item quote with no change orders unless we uncover something structural. Call (855) 901-7266 and we’ll schedule a time to come out.

FAQs – Therma-Tru Construction in San Bernardino
No. We’re an independent contractor who works on Therma-Tru doors without any manufacturer authorization or affiliation. That means our recommendations are based on what the door actually needs, not on protecting a dealer relationship. We use Therma-Tru OEM parts for the fit and warranty path they preserve, but nobody at Therma-Tru signs our paychecks.
We use Therma-Tru OEM hinges, multi-point hardware, weatherstrip, sweeps, and matching sidelite components whenever they’re available and priced reasonably. We go to quality aftermarket only for wear items where OEM is unavailable or the cost is out of line with the door’s age and condition. You’ll know which we’re using and why before we order anything.
Most sweep, weatherseal, and hardware replacements are done same-visit once we’re on site with the parts. A full re-hang with sill plate bolting and shear work takes longer, typically a day or two depending on what the rough opening needs. Structural reframing that changes the opening is a bigger job, and we’ll give you a realistic timeline with the estimate, not a hopeful one.
We service Fiber-Classic, Smooth-Star, Classic-Craft, and Therma-Tru patio and sidelite systems. If you have an older Therma-Tru door from the early 2000s or a newer Classic-Craft with a premium finish, we can assess it, source the right components, and do the repair or replacement without guessing.
A straightforward sweep and weatherseal replacement on a Therma-Tru entry door in San Bernardino typically runs on the lower end of a few hundred dollars, while a full re-hang with seismic bolting and shear work can push into the low thousands depending on what the framing requires. Replacement doors and structural reframing are priced per project. Call (855) 901-7266 for a free, written, line-item estimate, no obligation.
