Therma-Tru Construction in Corralitos, CA | Iron Beam Contractors
We provide independent Therma-Tru door and window construction service across Corralitos, CA, handling everything from rot remediation at the bottom rail to full entry-door replacements and adjacent window upgrades. What makes our work here different is that we spec every Therma-Tru door around unincorporated Santa Cruz County building review and wildland-urban interface fire-clearance requirements before anything gets ordered. If your door is fighting you, call (833) 756-5936 for a free estimate.
Why Corralitos Residents Choose Us for Therma-Tru Service
We’ve set and serviced Therma-Tru door systems across the Santa Cruz Mountains for years—including Watsonville Therma-Tru service—so we know how their fiberglass panels, rot-resistant frames, and multi-point locking hardware actually behave in coastal-influenced mountain weather. Our crew is independent, not authorized, sponsored, or warranty-backed by Therma-Tru, which means our recommendations are based on what holds up on your parcel, not a dealer program. Nolan Driscoll, our owner, built Iron Beam Contractors around the idea that a homeowner should know exactly what’s in the wall before we open it. That matters in Corralitos, where a door that looks fine from the inside can be hiding a rotted jamb leg or a failed sill pan underneath. We tie our work to the real conditions on your property: slope drainage, sun exposure, and whether the county’s fire-clearance review applies to your project.
We carry the full Therma-Tru sales & service capability, but we are blunt about repair-versus-replace decisions. If the slab is sound, we rebuild the threshold and replace OEM sweeps. If the bottom rail is gone, we say so.

Common Therma-Tru Construction Problems We Solve in Corralitos
Here’s what we actually see when we open up a Therma-Tru door on a Corralitos hillside or farmhouse parcel.
- Gel-coat chalking and microcracks on south- and west-facing fiberglass panels. Corralitos gets intense mountain sun followed by wet winters. Fiber-Classic and Smooth-Star slabs that face southwest take the worst of it. We refinish sound panels and replace ones where the fiberglass has cracked through.
- Rot and delamination at the bottom rail and jamb legs. Sloped driveways and uncovered porches throw splashback straight at the threshold. On older Corralitos homes, we regularly find the bottom rail soaked through three seasons running, and the fix is never just a sweep replacement.
- Multi-point lock and deadbolt misalignment. Hillside homes shift seasonally on expansive clay. The door drags the strike, the latch stops throwing clean, and suddenly the door seems warped. The door is usually fine. The slab moved. We reset the frame plane and rehang.
- Weatherstripping, sweeps, and corner seals that failed during winter rain. At the wildland-urban interface, a gap in the frame isn’t just a draft. It’s an ember entry point during fire season. We replace with OEM Therma-Tru weatherstrip kits and verify the full seal all the way around.
- Sidelite and glass-unit failures after storm-driven exposure. Corralitos sits in a narrow mountain valley where wind and driven rain load the door from one direction consistently. Failed corner seals on sidelites let moisture into the frame cavity, which eventually moves to the jamb. If we catch it early, it’s a glazing and seal job. If not, the whole frame comes out.
Therma-Tru Service in Corralitos: What Local Conditions Mean for Your Equipment
Because Corralitos parcels are unincorporated Santa Cruz County, a door or window change that alters the building envelope can trigger county review. On hillside lots near the wildland-urban interface, exterior door and glazing specs often have to satisfy fire-clearance and egress requirements that a Therma-Tru in Freedom or Gilroy city permit wouldn’t. That changes which Therma-Tru door and glass configuration we specify before anything gets ordered.
This is the part that trips up contractors used to working subdivisions. A Therma-Tru Classic-Craft door with the wrong glass pack on a west-facing Corralitos hillside may not clear county review, and the homeowner doesn’t find out until the project is already bought. We pre-check the fire-clearance and egress constraints for your parcel before we ever spec the door. That’s not something you get from a generic door vendor. If the structure makes sense on paper, it’ll hold in the field. If it doesn’t make sense on paper, we fix it before we touch a beam.
Therma-Tru Models & Products We Service in Corralitos
We service the full residential Therma-Tru range: Fiber-Classic entry doors, Smooth-Star fiberglass doors, Classic-Craft door series, and Benchmark factory-finished doors, including Therma-Tru service in Interlaken. On the parts side, we use OEM Therma-Tru replacement sills, sweeps, weatherstrip kits, and lock hardware where the door slab and frame are still sound. When OEM is back-ordered, we use quality aftermarket glass and finish systems that match the existing config without waiting six weeks for a factory part.
We stock common OEM sweeps, corner seals, and multi-point lock components for fast turnaround on Corralitos jobs, so a sticking deadbolt or leaking threshold doesn’t sit for a month.

FAQs – Therma-Tru Construction in Corralitos
No, because there is no city permit department for Corralitos. Unincorporated Santa Cruz County reviews building envelope changes, and hillside parcels in the wildland-urban interface often require fire-clearance and egress review before a door swap is approved. We handle the county paperwork on your behalf, so the permit doesn’t become your problem. Call (833) 756-5936 and we’ll tell you what your parcel triggers before we order anything.
Usually not. Seasonal hillside movement on expansive clay shifts the frame plane slightly, which throws the strike out of alignment and makes the door drag. We reset the frame and adjust the multi-point hardware, and the door works again. If the door is actually failing, the rot or panel cracks will be visible at the bottom rail or jamb, and we’ll show you photos of what we found.
The fiberglass skin is waterproof. The bottom rail core and jamb legs are not. On Corralitos parcels where a sloped concrete walk drains straight at the threshold, splashback keeps the bottom of the door wet all winter, and the core eventually delaminates. We rebuild the sill pan and flashing, reset the door on a draining composite threshold, and install fresh OEM sweeps so the corner stays dry.
Yes. Parcels in the wildland-urban interface can require specific glazing ratings, door construction, and ember-resistant sealing that a standard pre-hung door won’t meet. We verify the requirements for your parcel in unincorporated Santa Cruz County before we spec the Therma-Tru model and glass pack. Call (833) 756-5936 and we’ll walk the site with you.
If the slab and frame are sound, repair almost always beats replacement: new OEM sweeps, weatherstrip, and lock hardware run a fraction of a full door cost. If the bottom rail is rotted through or the fiberglass panel is cracked, we tell you straight: replacement beats patching, because a rebuilt door on a wet hillside threshold will fail again. We’ll quote both options and let you decide.
