Therma-Tru Construction in Boulder Creek, CA | Milpitas Construction
We handle Therma-Tru repair in Ben Lomond and across Boulder Creek, from a single sagging slab on a redwood-shade cabin to full door packages on CZU rebuilds. The one thing that makes our Therma-Tru work different here: we treat every door as part of a fire-hardening assembly, not just an entry. County fire-clearance inspections after the 2020 CZU Lightning Complex fire look hard at ember gaps, sill gaskets, and door-to-frame seals, and we’ve built our service approach around passing those walk-throughs the first time. Call (877) 752-4194 and we’ll come look at what you’ve got.
Why Boulder Creek Residents Choose Us for Therma-Tru Service
We’ve been hanging, tuning, and re-hanging Therma-Tru doors and entry systems across the Santa Cruz Mountains for years, including Therma-Tru in Felton, so we know how their fiberglass slabs, rot-resistant frames, and multipoint hardware actually behave under redwood-shade damp and wildfire-hardening requirements, not just how they look in a showroom. Ken Stafford, who owns Milpitas Construction, got his construction technology training at Evergreen Valley College in San Jose and has spent two-plus decades working Bay Area residential builds. He’ll tell you a door that drags on a Boulder Creek pier-and-post floor is rarely just a hinge problem. We’re an independent Therma-Tru service provider. We’re not authorized, sponsored, or warranty-endorsed by Therma-Tru, and we don’t pretend to be. We source genuine Therma-Tru slabs, frames, sills, and multipoint hardware when the structure is sound, and we use quality aftermarket weatherstrip, sweeps, and finish hardware where OEM equivalents are backordered, which happens after big rebuild pushes. You get straight answers about whether a door should be repaired or replaced, and exactly what parts are going in.

Common Therma-Tru Construction Problems We Solve in Boulder Creek
- Rotted bottom rails on Fiber-Classic and Smooth-Star doors. The wood-composite stiles and bottom rails wick moisture where the slab meets the threshold. On Boulder Creek cabins built on pier-and-post foundations, slope movement flexes the floor and opens micro-gaps at the sill, so water tracks in and rot climbs up from the bottom. We see this on Bear Creek Road, Two Bar, and the side streets off Highway 9, and it’s a structural call, not a cosmetic one.
- Multipoint locks and deadbolts that drift out of alignment. Pier-and-post homes settle seasonally as the clay and redwood duff under them expands with heavy winter rainfall and contracts in summer. Therma-Tru multipoint hardware is precise, which means it does not forgive a frame that’s moved even a quarter inch. Doors drag, latches stop catching, and a security issue becomes a fire-clearance fail when the door won’t seal.
- Cracked or blistered fiberglass skins at the lock bore and hinge stile. Older Fiber-Classic slabs take years of wet-season swelling followed by dry summer heat, and the skin eventually gives at the stress points. It’s not a warranty call for us to chase; it’s a judgment call about whether the existing frame is true enough to take a new slab.
- Flattened weatherstripping, sweeps, and sill gaskets. Atmospheric-river storms drive wind-blown rain against door bases on mountain slopes. Once the sweep flattens or the sill gasket pulls loose, water tracks behind the frame and into the wall. That’s a rot problem and an ember-gap problem in WUI rebuilds, and county inspectors will flag it.
- Thresholds that have pulled away from settled slabs. On steep graded lots, a threshold is only as good as the framing under it. We regularly reset thresholds and re-seal door pans on CZU-rebuild jobs where the previous contractor rushed the rough opening to hit a fire-clearance deadline.
Therma-Tru Service in Boulder Creek: What Local Conditions Mean for Your Equipment
Because Boulder Creek rebuilds after the CZU Lightning Complex have to clear Santa Cruz County fire-clearance inspections, exterior door assemblies here routinely get scrutinized for ember- and gap-sealing alongside roof class and deck material. A generic door guy from the flats might not think about that. We do. A Therma-Tru door’s sill gasket and sweep condition is part of the fire-hardening conversation, not just curb appeal. When an inspector runs a flashlight along the bottom of a Fiber-Classic slab and sees daylight at the corner, that door fails the walk-through. We’ve seen it happen on rebuilds up and down Highway 9 and off Bear Creek Road, and it’s usually the same story: someone installed a quality door into a settling opening without re-flashing the pan or checking the frame for plumb. For Therma-Tru repair in Lompico and nearby areas, we take the same careful approach. On a CZU-rebuild cabin up a steep graded lot off Bear Creek Road, our crew pulled a sagging Fiber-Classic entry door whose bottom rail had rotted where the sill met a settling pier-and-post floor, and the multipoint latch had stopped catching. We reset the frame plumb, installed a new Therma-Tru fiberglass slab with a fresh sill and weatherstripping, and re-hung the multipoint hardware so the door sealed tight for the county fire-clearance walk-through. The homeowner got a door that closes and latches in one motion and passes the gap-and-ember review. That’s the standard we build to in Boulder Creek.
Therma-Tru Models & Products We Service in Boulder Creek
We service the full Therma-Tru lineup: the Fiber-Classic entry door series with its woodgrain fiberglass texture, the Smooth-Star series for a flat clean face, and the Classic-Craft American Style collection with its deeper panel profiles and security plate options. We work on Therma-Tru door systems built with Tru-Defense framing components and multipoint locking hardware. Our parts sourcing is honest: genuine Therma-Tru slabs, stiles, sills, and multipoint hardware when the opening and hinge stiles are sound; quality aftermarket weatherstrip, sweeps, and finish hardware where OEM stock is backordered after big rebuild pushes. We do not put cheap import seals on a door that has to pass a WUI inspection. When the stile or bottom rail is rotted or the fiberglass skin is cracked through, a new slab in the existing frame is usually the smarter spend than chasing a repair, and we’ll tell you that straight. Our broader Therma-Tru sales & service work covers everything from single door swaps to full entry packages on additions and ADUs.

AfterTherma-Tru Service Pricing in Boulder Creek
What you’ll pay depends on what the door is attached to. On a flat lot with a stable foundation, a wedge-and-seal tune-up is a routine service call. On a steep Boulder Creek lot with a pier-and-post frame that’s been settling for forty years, the job may involve resetting the frame and rebuilding the threshold before the new slab goes in. Here are the construction line-items that typically frame our Therma-Tru-adjacent work:
| Service | Price Range |
|---|---|
| Roof Replacement | $8000 – $20000 |
| Roof Repair | $400 – $1800 |
| Full Kitchen Remodeling | $14000 – $45000 |
| Full Bathroom Remodeling | $9000 – $28000 |

FAQs – Therma-Tru Construction in Boulder Creek
Yes. We do full-scope construction, so the same crew managing your roof replacement or kitchen remodel can also re-hang or replace your Therma-Tru entry door and get it to pass the county fire-clearance inspection. On CZU rebuilds, sequencing the door work with the roof and exterior envelope keeps you out of a pass-fail gap at final inspection. Call (877) 752-4194 to get the door added to your rebuild scope, and we’ll fold it into one contract.
No. We’re an independent general contractor serving Boulder Creek and the Santa Cruz Mountains. We install and service Therma-Tru doors, and we source genuine Therma-Tru parts, but we are not manufacturer-affiliated, authorized, or warranty-endorsed. Any factory warranty question goes to Therma-Tru directly. What we own is the installation quality, and that’s what determines whether the door performs.
Both, and we’ll tell you which is which before we order anything. We use genuine Therma-Tru slabs, frames, sills, and multipoint hardware when the structure is sound, because those parts were engineered to work together. We use quality aftermarket weatherstrip, sweeps, and finish hardware when OEM equivalents are backordered or not available, which happens during big rebuild pushes after fire seasons. For a door that has to pass a Boulder Creek WUI inspection, we will not substitute cheap seals.
A day for most repairs: re-hinging, resealing, re-weatherstripping, or realigning multipoint hardware. A full slab replacement on a settled pier-and-post opening can take two days if we’re resetting the frame and rebuilding the threshold. Rebuild-scope door installations sequence with the rest of the project schedule. Call (877) 752-4194 and we’ll give you a realistic window based on what you’ve got.
It depends on whether the bottom rail can be sealed and re-hung or the whole slab needs replacing. If the frame is plumb and only the seal has failed, it’s a repair call. If the wood-composite bottom rail is soft through, you’re looking at a new slab in the existing frame, and that’s a smarter spend than patching rot that will come back after one wet winter. Call (877) 752-4194 for a straight quote, free.
