Therma-Tru Construction in Boulder Creek, CA | San Bruno Construction
If you’re searching for Therma-Tru construction service in Boulder Creek, here’s the direct answer: we’re an independent general contractor that has installed, repaired, and retrofitted Therma-Tru entry doors across Boulder Creek for years, and the single factor that separates our work here from anywhere else is the fire-hardening requirement. Nearly every door we touch in Boulder Creek has to function as part of an ember-resistant entry assembly, not just a good-looking slab. We serve the entire 95006 ZIP code. Noel Carvalho, owner of San Bruno Construction, grew up off El Camino Real in San Bruno and trained in construction technology at Skyline College, and our crews understand how mountain moisture, hillside movement, and canyon wildfire codes interact with Therma-Tru fiberglass doors. Call (866) 472-1908 for a free estimate on Therma-Tru sales & service in Boulder Creek.
Why Boulder Creek Residents Choose Us for Therma-Tru Service
We know Therma-Tru doors the way a mechanic knows a specific engine, but with local context that only comes from working these lots. The Fiber-Classic, Smooth-Star, and Classic-Craft lines each behave differently when they’re installed on a shaded canyon slope with poor drainage and seasonal seismic settling. A door that would hold square on a flat Scotts Valley tract home will rack out of alignment on a Boulder Creek hillside within a few wet winters if the opening wasn’t prepped right in the first place. Noel’s two-plus decades running residential projects across San Mateo County taught him to read load paths and drainage patterns before a single tool comes out of the truck. That’s the difference. We’re not reading a spec sheet when we assess your Therma-Tru door. We’re reading how the soil, the slope, and the surrounding redwood canopy are working against it. We’re an independent contractor, not an authorized Therma-Tru dealer. That matters because our recommendations come from what the door actually needs, not from a dealer program pushing a particular upgrade.

Common Therma-Tru Construction Problems We Solve in Boulder Creek
These are the five failure patterns we see most often on Therma-Tru doors in Boulder Creek homes. If any of these sound familiar, call us for a straight assessment.
- Sill and threshold rot from shaded canyon moisture: On parcels along the San Lorenzo River corridor, persistent moisture wicks under Therma-Tru adjustable sills and composite thresholds. We regularly find soft framing and delaminated sill noses on doors that look fine from the inside. The rot is working from underneath while the face of the sill still looks intact.
- Fiberglass skin cracking and gel-coat blistering at the lock rail and hinge stile: Hillside foundation movement and seasonal seismic settling rack the jamb out of square. When the panel is loaded unevenly month after month, the fiberglass skin cracks at the stress points. This is a Boulder Creek problem, not a manufacturing defect, and it’s why we check foundation and framing before we ever order parts.
- Finish failure on stained Fiber-Classic and Classic-Craft Mahogany doors facing south or west: Long dry summers and UV exposure at mountain elevation break down stain and clear coat faster than homeowners expect. Once the finish goes, the fiberglass grain detail starts checking and the door loses its weather resistance. We re-stain with UV-rated finishes and advise on overhang or porch protection where needed.
- Weatherstrip and sweep failure on wind-driven winter storms: Boulder Creek takes heavy winter rain on a steep terrain, and wind pushes water against entry doors from angles valley builders don’t plan for. Worn sweeps and compressed weatherstrip let water and cold air in, and on fire-hardened homes they also leave an ember entry gap at the door-to-jamb seam.
- Racked jambs from hillside settling: The jamb goes out of square, the door starts sticking or swinging open on its own, and the lockset stops lining up with the strike plate. We reframe and reset the opening, replace the jamb if it’s too far gone, and install a door that closes on one hand.
Therma-Tru Service in Boulder Creek: What Local Conditions Mean for Your Equipment
Almost every Boulder Creek door replacement we do is also a fire-hardening and defensible-space job. The door has to sit in a rebuilt, ember-resistant surround with noncombustible detailing, because the surrounding redwood and conifer forest means the entry assembly, not just the door slab, is what gets evaluated. A homeowner on a shaded parcel off the San Lorenzo River corridor may think they just need a new Therma-Tru slab. What they actually need is the slab plus a re-flashed opening, fire-rated trim, noncombustible kick plate or threshold transition, and a drainage detail that keeps winter runoff from pooling at the foundation. Homes on shaded canyon slopes see persistent moisture and root intrusion that rot decks and foundations faster than sun-exposed valley lots, so mountain contractors build in more drainage and rot-resistant detailing than neighboring lowland builders would. That’s the standard we work to on every Therma-Tru install in Boulder Creek. We don’t patch a door and leave the surrounding assembly vulnerable. We treat the entry as one system.
Therma-Tru Models & Products We Service in Boulder Creek
We install, repair, and retrofit across the Therma-Tru line: the Fiber-Classic collection, Smooth-Star fiberglass doors, Classic-Craft series including the American Style and Canvas collections, and the Fiber-Classic Mahogany and oak-grain-stained fiberglass doors common on Boulder Creek homes. On the parts side, we use Therma-Tru OEM sills, sweeps, weatherstrip, hinges, and glass frames wherever the door itself is structurally sound. Aftermarket thresholds rarely match the door’s drainage profile, and in a canyon climate that drains poorly to begin with, the wrong threshold just accelerates the rot. When the stile or skin is cracked through, or the framing behind it is rotted, we tell homeowners straight that a new door assembly is cheaper in the long run than patching a door that’s already failing. We keep common OEM parts stocked locally for faster Boulder Creek turnaround.

What drives cost on a Boulder Creek Therma-Tru job is the condition of the opening, not just the door. If the framing is solid, a slab or pre-hung replacement is straightforward. If the jamb is racked, the sill is rotted, or fire-hardening upgrades are required, the scope grows, as it does for Therma-Tru repair in Ben Lomond.

FAQs – Therma-Tru Construction in Boulder Creek
Can you match a new Therma-Tru door to the redwood contemporaries and older mountain cabins common in Boulder Creek? Yes. We’ve installed Therma-Tru Fiber-Classic Mahogany and Classic-Craft doors on redwood contemporaries and mid-century cabins throughout Boulder Creek and Therma-Tru in Felton, and we know which finishes and glass package options sit naturally against redwood siding and cedar shake. The door doesn’t have to look like a city condo door dropped into a mountain setting. Call (866) 472-1908 and we’ll bring finish samples to your door.
Are you an authorized Therma-Tru dealer? No, and that’s intentional. We’re an independent contractor serving Boulder Creek, not authorized, sponsored, or endorsed by Therma-Tru. That means when we recommend an OEM sill or a full door replacement, the recommendation is based on what the opening needs, not on a dealer relationship or sales quota.
Do you use genuine Therma-Tru parts on repairs? Yes, whenever the door is structurally sound. We use Therma-Tru OEM sills, sweeps, weatherstrip, hinges, and glass frames because aftermarket parts rarely match the door’s drainage profile. On a shaded Boulder Creek canyon lot with heavy winter rain, the difference between an OEM sill and a generic one can be the difference between five years and fifteen years of service.
How long does Therma-Tru door service take in Boulder Creek? A straight slab or pre-hung replacement on a solid opening is typically a one-day job. When we have to reframe a racked jamb, replace rotted sill framing, or bring the entry up to fire-hardening standards, it stretches to two or three days. We’ll tell you the honest timeline at the estimate, not after we’ve started.
How much does a Therma-Tru door replacement cost in Boulder Creek? Door-specific pricing depends on the model line, glass options, and condition of the opening. Window replacement runs $4,500 – $15,000, and impact-rated window installation runs $8,000 – $25,000. Kitchen and bathroom remodels that include Therma-Tru door work fall within $14,000 – $45,000 and $9,000 – $28,000 respectively. The best way to get a real number is a free on-site estimate.
