Therma-Tru Construction in Seven Trees, CA | Workshop Contractors
We’re an independent Therma-Tru service contractor working across Seven Trees, CA. We install, repair, and reframe Therma-Tru entry and patio doors on the postwar ranch homes that define this unincorporated pocket of San Jose. The thing that makes our Therma-Tru work different here: we do not separate the door from the wall it hangs in. On a 1950s stucco ranch with a settled foundation or an unpermitted addition, that’s the difference between a door that closes square and one that sticks every August. Call us at (844) 384-3361 to schedule a free estimate.
Why Seven Trees Residents Choose Us for Therma-Tru Service
Most door companies sell slabs. We build openings. Noel Figueroa, our owner and Seven Trees General Contractor, learned framing before he ever hung a prehung unit, and that order of operations matters in Seven Trees. These homes don’t have perfectly plumb wall openings anymore. They have 70 years of settling, stucco patches, and room additions that were never permitted. So when we install a Therma-Tru Smooth-Star or Classic-Craft, we’re checking the rough opening, the sub-sill, the jamb legs, and the header before we ever drive a shim.
We carry Therma-Tru sales & service expertise across the full product line, and we stock OEM slabs, sweeps, hinges, and weatherseal kits for fast turnaround in 95111. We’re not a manufacturer-authorized dealer. We’re better positioned than one for Seven Trees, because a dealer can hand you a door. We can tell you whether the door is the problem or the wall behind it is.

Common Therma-Tru Construction Problems We Solve in Seven Trees
- Sun-baked fading and chalk on south and west entries. Seven Trees gets the full Santa Clara Valley summer. A Smooth-Star fiberglass slab facing south or west will fade, chalk, and lose its paint film years before a shaded north entry does. We strip, prep, and refinish where the slab is sound, or replace when the surface has degraded past the point of a durable repaint.
- Doors out of square from settling and unpermitted additions. Original builder-grade Therma-Tru slabs on these 1940s – 1960s ranches are set into openings that have moved. Add an unpermitted room addition that shifted the framing, and you get a door that sticks at the top corner while the hardware still works fine. We reframe and re-hang rather than shaving the slab to fit a bad opening.
- Rotted jamb legs and sub-sills from winter rain wicking. Mild wet winters mean water runs down stucco, pools at the threshold, and soaks upward into the jamb. Deferred rot on fascia and eaves dumps even more water at the door base. The door looks fine from the outside. The sub-sill is mush. That’s a framing repair, not a weatherstrip replacement.
- Whistling and daylight gaps around the perimeter seal. Original single-pane sidelites and builder-grade weatherstrip let hot valley air and fine grit past the sweep. Owners notice the draft before they notice the door itself. We replace with Therma-Tru OEM sweeps and seals sized to the actual slab, not a universal strip from a big-box shelf.
- Patio and sliding door systems binding on narrow flag lots. Seven Trees’ small lots off Monterey Highway and Seven Trees Boulevard put patio doors close to fences and paved areas. When the slab settles or the deck heaves, a Therma-Tru sliding system binds on the track. We re-level, adjust rollers, and replace damaged track sections as part of a full patio door service.
Therma-Tru Service in Seven Trees: What Local Conditions Mean for Your Equipment
Here’s the thing most people do not know until they’re in the middle of a door replacement: Seven Trees is unincorporated Santa Clara County, not the city of San Jose. That means any Therma-Tru service in San Jose entry or patio door that changes the rough opening on a remodel or addition is permitted and inspected through the County. Not San Jose’s building department. The County keeps its own records, and when we pull them for a door opening change, we regularly find the original permits don’t match the house standing there now. A 1954 ranch on Seven Trees Boulevard with a permitted two-bedroom footprint and an unpermitted back addition means the Therma-Tru door into that addition was never on any record. When we open that wall to reframe, the County inspector wants to see what we find. That’s not a delay to fear. It’s a delay to plan for, and we handle the permitting, the inspection schedule, and the paperwork on your behalf. A door swap in Seven Trees can be a slab job or a framing-and-inspection job, and you won’t know which until someone who knows County rules looks at the opening.
Therma-Tru Models & Products We Service in Seven Trees
We work on the full Therma-Tru residential range: Smooth-Star fiberglass entry doors, the Fiber-Classic collection, Classic-Craft series, and Therma-Tru patio and sliding glass door systems. For sound frames, we use Therma-Tru OEM slabs, hinges, sweeps, and weatherseal kits. The proprietary sill and sweep profiles are what make the assembly weathertight, and an aftermarket sweep never quite seats the way the factory part does. When the jamb or sub-sill is rotted, which we see on Buena Vista Therma-Tru service and Seven Trees ranches with deferred eave maintenance, a new prehung unit is the honest fix. Patching a rotted opening and calling it done is how you get a door that fails again in three winters.
We also extend Therma-Tru door work into the broader scope we manage as a general contractor. A kitchen remodel that moves an exterior wall is a door project. A bathroom remodel that widens a rough opening for a new Therma-Tru patio access is a framing project plus a finish project. One contract covers it.

FAQs – Therma-Tru Construction in Seven Trees
Santa Clara County. Seven Trees is not within San Jose city limits, so any permit for a door opening change, structural reframe, or addition goes through the County’s building department. We pull those permits and manage the inspection schedule so you don’t spend your Tuesday waiting for an inspector who’s booked in Gilroy. Call (844) 384-3361 if you want us to handle it from day one.
We start with a County records check to see what’s on file versus what’s actually standing. If the addition was never permitted, the door opening was likely never inspected either. We’ll tell you what’s involved, what a reframe costs, and what the County will want to see before any owner has to decide anything. Call (844) 384-3361 to get us on site.
Fading is UV damage to the paint film and gel coat, driven by the same Santa Clara Valley sun that bakes every south and west wall in Seven Trees. Sticking is usually not the same problem, it’s the opening moving with seasonal heat and moisture. The door swells. The frame doesn’t. Fixing both means refinishing the slab and checking the rough opening for square, a Therma-Tru repair in Cambrian Park approach we apply here too. It’s a two-part repair most door companies handle as two separate visits. We handle it as one.
Often both. A leaking eave or clogged gutter dumps water at the door base, and once the sub-sill wicks it up, the jamb rots from the inside out. We’ll check the fascia, eave, gutter, and threshold before we touch the door, because replacing a slab under a leaking roof line is throwing money at the symptom. Roof repair in Seven Trees typically runs $400 – $1,800, and it’s the repair that makes the door replacement worthwhile.
Yes, if the frame is sound and the opening is square. We’ll assess the jamb legs, sill, and header, then order a Therma-Tru slab to match the original size and handing. If the frame is rotted or out of square, we’ll tell you straight that a prehung unit is the better spend. Call (844) 384-3361 for a free assessment and exact quote.
