Therma-Tru Construction in Lompico, CA | Seaside Contractors
We provide independent Therma-Tru construction service across Lompico, from entry door replacements and patio door rebuilds to full kitchen and bath remodels that start with the door rough opening and end with the trim. What separates our Therma-Tru work in Lompico is how we scope it: the canyon’s wet-season runoff, redwood-shade damp, and steep-lot foundation movement mean we re-square openings and flash sills differently than we would on a flat Scotts Valley lot. Call (833) 589-8103 for a free estimate. We’re a Lompico General Contractor that handles the door, the rough opening, and whatever remodel work sits behind it.
Why Lompico Residents Choose Us for Therma-Tru Service
We’ve installed, trimmed out, and repaired Therma-Tru in Mount Hermon and across the Santa Cruz Mountains for years, so we know how Fiber-Classic slabs, Smooth-Star skins, and patio door hardware behave when the redwood canopy keeps everything damp for six months at a time. As an independent contractor we’re not tied to Therma-Tru’s dealer network. That means we recommend the right fix or replacement without a brand quota. Glen Sorrento, our owner, grew up watching Foster City lagoon-side homes get built and rebuilt, studied building construction technology at College of San Mateo, and has spent two-plus decades working through nearly every project type the region throws at a contractor. He’ll look at a Therma-Tru spec sheet and give you a straight answer on whether that slab is worth saving. Let’s figure out what the job actually needs – then we’ll talk materials.

Common Therma-Tru Construction Problems We Solve in Lompico
- Bottom-rail rot and delamination. Wood stiles and rails on older Therma-Tru slabs swell at the bottom rail when winter rain splashes off steep decks and saturated Lompico ground. The fix often means a new slab, not a patch job, because once water wicks into the bottom rail the damage keeps spreading behind the paint film.
- Fiberglass skin cracks and bubbling on shaded entries. North-facing and redwood-shaded Lompico entries hold moisture against the door surface. Therma-Tru fiberglass skins develop hairline cracks and bubbling where that damp wicks behind the paint film. We see this regularly on cabins and custom homes tucked into the canyon.
- Factory-finish peeling and UV-fade on south and west exposures. Doors that catch those few hours of direct canyon sun will fade and peel at the finish layer. It’s often misdiagnosed as a glass seal failure. We check the slab surface before ordering glass work that isn’t needed.
- Sticking, out-of-square patio doors in 1970s-80s additions. Lompico’s older additions were often built on slope-movement foundations, and the rough openings shift over time. That leaves Therma-Tru patio sliders binding on hinges, failing sweeps, or refusing to latch cleanly.
- Sill flashing failures that leak into the wall cavity. Rain splash off redwood-shaded decks saturates the sill area. When the original flashing was done wrong, water runs behind the siding and rots the subfloor before you see anything on the interior. We re-flash and seal every Therma-Tru sill we touch.
Therma-Tru Service in Lompico: What Local Conditions Mean for Your Equipment
Because Lompico lots are often informally subdivided on private wells and septic, exterior door and window replacements that change the opening size can trigger a Santa Cruz County review that asks for well-yield and percolation documentation before the permit is issued. That’s a Lompico-specific reality most door contractors never mention, and it changes how we scope Therma-Tru work here. We measure and scope Therma-Tru door swaps to keep as much of the existing rough opening as possible, because a slab replacement that stays within the original frame is a repair, not a structural change. The moment your new door needs a bigger header, wider king studs, or a relocating of the rough opening, you’ve potentially bought yourself a geotechnical and septic review. We’ve navigated that permit path on enough Lompico properties to know when it’s worth pushing and when it’s cheaper to stay within the existing opening. That’s the difference between a contractor who knows Lompico and one who treats it like any other zip code.
Therma-Tru Models & Products We Service in Lompico
We work on the full Therma-Tru product range you’ll find in Lompico homes: Fiber-Classic entry doors, Smooth-Star fiberglass doors, Classic-Craft door series, and Therma-Tru patio door systems in both fiberglass and steel. For Therma-Tru we use OEM replacement slabs, glass lites, sweeps, and hinge sets when the frame and sill are sound. We carry quality aftermarket weatherstripping and thresholds for quick fixes, but we won’t substitute generic hardware on a Therma-Tru multipoint or hinged patio system, because the fit tolerances don’t hold in this climate. When a door is within a few years of end-of-life, honest math usually favors a full replacement over rebuilding a rotten bottom rail. We’ll walk you through that math before you spend anything.

What drives cost on a Therma-Tru job in Lompico? The rough opening condition is first. If the framing is square and the sill flashing is intact, a slab swap is straightforward. If we’re re-squaring an opening that settled on slope movement, or replacing rot in the subfloor under the threshold, labor climbs. Your free estimate includes a look at the opening, the existing door, and the flashing, so you’ll know exactly what you’re paying for before we start. Call (833) 589-8103 to schedule one.

FAQs – Therma-Tru Construction in Lompico
Can you replace just the Therma-Tru door slab without pulling the whole frame in my Lompico cabin?
Yes, when the frame and sill are sound we can set a new OEM Therma-Tru slab into the existing opening, re-shimming and re-hanging as needed. If the bottom rail has swollen or the frame has shifted on slope movement, we’ll tell you whether a full frame replacement is the smarter spend. Call (833) 589-8103 and we’ll take a look.
Why is the bottom of my Therma-Tru entry door soft and bubbling in Lompico?
That’s water wicking into the bottom rail, almost always from rain splash off a deck or saturated ground. The redwood-shade damp around Lompico keeps that area wet for months, and once the rail starts to delaminate the damage spreads. Replacement is usually the right call. Call (833) 589-8103 to have us inspect it.
Do you need a permit to swap a Therma-Tru patio door in Lompico?
In most Lompico situations, a like-for-like slab swap within the existing rough opening doesn’t require a permit. If you’re changing the opening size or moving framing, Santa Cruz County may ask for well-yield and percolation documentation before issuing one, because Lompico is on private wells and septic. We scope the work to keep that off your plate when possible.
Will a new Therma-Tru fiberglass door hold up to Lompico’s wet winters and wildfire zone?
A properly flashed and sealed Therma-Tru fiberglass slab holds up well in Lompico’s climate, but the installation details matter more than the brand here. We re-square the opening, flash the sill to shed water, and use OEM hardware so the slab stays square through wet winters and dry fire seasons. The door itself isn’t the weak point; bad flashing is.
Can you match my existing Therma-Tru door style and color for a Lompico addition?
Yes, Therma-Tru’s Classic-Craft and Fiber-Classic lines offer a range of panel profiles and finish options that let us match an existing door for an addition or remodel. We’ll bring samples to your Lompico property so you can see them against the existing finish in the canyon’s light. Call (833) 589-8103 to set that up.
