Therma-Tru Construction in Pacifica, CA | San Bernardino Contractors
We provide independent Therma-Tru entry door service across Pacifica, from new Fiber-Classic and Smooth-Star installations to repair work on doors that have spent years in salt fog. The thing that makes our Therma-Tru work different here: we know a Pacifica door leak is usually the roof flashing above the header, not the door itself. Call (855) 473-5620 for a free estimate. We’re a full-service general contractor that handles the entire exterior envelope, so when we fix a door, we trace the water to its source.
Why Pacifica Residents Choose Us for Therma-Tru Service
We’ve fitted and serviced Therma-Tru fiberglass and steel entry systems across the Peninsula for years, including Therma-Tru service in South San Francisco, and on this stretch of coast that means we know exactly how a Fiber-Classic or Smooth-Star slab behaves when it lives in salt fog rather than sun. Ruben Castillo runs our crew, and he came up learning framing, concrete, and exterior work hands-on, so when we open up a Therma-Tru jamb on a Linda Mar hillside house, we already know what we’re going to find behind it. We’re an independent contractor, not authorized, sponsored, or warranty-backed by Therma-Tru, and we say so up front. That independence means we call it like we see it: when the slab and frame are square but seals have failed, we repair. When the bottom rail is soft, replacement is the honest call.
We carry Therma-Tru OEM components for common Fiber-Classic and Smooth-Star models, and we stock aftermarket stainless hardware and sill pans for the corrosion situations that plated parts simply can’t survive in Pacifica’s marine layer. Most Therma-Tru service in Pacifica sits somewhere between a door fix and a roof fix, and because we’re a Therma-Tru sales & service contractor who also handles roofing, flashing, and siding in-house, you don’t get bounced between a door company and a roofer. One contractor, every phase.

Common Therma-Tru Construction Problems We Solve in Pacifica
- Rusted sill pans and plated hardware from salt air. The onshore wind carries salt constantly, and it pits and lifts factory finishes on steel-edged frames, hinges, strike plates, and multipoint hardware long before the fiberglass slab shows any wear. You’ll see white corrosion blooms on the hardware while the door face still looks new. We swap those plated parts for stainless and set a new sill pan that won’t rot through in five years.
- Wind-driven rain finding failed weatherstripping and sill pans. Pacifica storms push rain horizontally off the marine layer, and when the sweep or threshold seal has dried out, water drives straight through to the bottom rail. The door stays wet at the base, same as the deck ledger problem every Linda Mar homeowner knows. If the bottom rail still feels solid, we reseal and reset. If it’s soft, you need a new slab.
- Wet jamb legs and brickmold behind the slab. The fog here never fully dries the underside of a door overhang, so wood frame components behind the fiberglass stay damp for months at a time. They swell, hold mold, and eventually the whole frame shifts out of square. We open the trim, replace the rotted wood, and reassemble so the Therma-Tru slab sits plumb again.
- Coastal condensation on single-glazed sidelites. When the marine layer hangs over Park Pacifica in summer, the interior face of a poorly insulated sidelite sweats. That moisture runs down and stains the slab edge and threshold. We can upgrade the glazing and reseal the assembly, or replace the sidelite panel if it’s gone too far.
- Roof-to-wall flashing failures above the entry header. This is the Pacifica signature problem, more than any other coast town we work. The roof above the door catches wind-driven rain, the flashing fails, and water dumps onto the header every storm. The door gets blamed, but the door is just the symptom. We fix the roof section and flashing first, then reseal the threshold below.
Therma-Tru Service in Pacifica: What Local Conditions Mean for Your Equipment
Bluff-top and Linda Mar streets, like those near Therma-Tru service in Broadmoor, face open ocean wind-driven rain with almost no drying season. A Therma-Tru entry door here lives in permanent moisture, so the door’s sill, flashing, and roof-to-wall detail above the header matter more than the slab finish. We routinely find that a leaking Pacifica entry door starts at the roof and flashing above the header, not at the door. That’s the difference between Pacifica and an inland Peninsula town: in Burlingame or San Mateo you can miss a bad flashing for years and never know. In Pacifica, the first hard winter storm tells you. When we get called for a “door leak” on a bluff-top house, we look up before we look down. If the roof-to-wall flashing is compromised above the entry, no amount of new weatherstripping or threshold work will keep water out; it’ll just come back next storm.
Therma-Tru Models & Products We Service in Pacifica
We service and install the full Therma-Tru entry line that shows up in Pacifica homes: Fiber-Classic collection entry doors, Smooth-Star fiberglass entry doors, Classic-Craft American Style door series, and patio and sidelite assemblies with factory-finish frames. Parts approach is straightforward: we use Therma-Tru OEM slabs, sills, and sweep/weatherstrip kits where they still match the existing frame. Where salt corrosion has already killed the original plated parts, we switch to quality aftermarket stainless hardware and sill pans, because putting the same plated part back in a Pacifica fog belt just guarantees a callback. We keep common sweep kits, threshold seals, and stainless hardware on the truck, so most Pacifica service visits don’t need a second trip to the supply house.

AfterTherma-Tru Service Pricing in Pacifica
Because most Therma-Tru work in Pacifica is tied to the moisture and flashing problems around the door rather than the slab itself, the price range depends on what we find once we open it up, similar to what we’d assess during Therma-Tru repair in San Bruno. Here are the ranges for the work we most often combine with Therma-Tru door repair or replacement on Pacifica homes:
| Service | Price Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Roof Repair | $400 – $1,800 |
| Roof Replacement | $8,000 – $20,000 |
What drives the cost: whether the roof flashing above the entry needs repair along with the door, whether the frame can be saved or must be rebuilt, and whether you choose a replacement Therma-Tru slab or just seals and hardware. A free estimate means we open the trim, show you what’s wet, and give you a line-item quote, so you know before any work starts. Call (855) 473-5620 to book one.

FAQs – Therma-Tru Construction in Pacifica
The fiberglass slab itself won’t rot, that’s the whole point of a Fiber-Classic or Smooth-Star. What rots in Pacifica is the wood frame behind it, the jamb legs, brickmold, and the sub-sill, because the fog never lets them dry out. We inspect the frame every time, because a sound slab on a rotten frame is still a failing door. Call (855) 473-5620 and we’ll take a look.
Salt-laden onshore air attacks plated hardware continuously, especially within a few blocks of the ocean. Factory plated hinges, strike plates, and multipoint hardware fail in years, not decades, and the fix is stainless or marine-grade aftermarket hardware. We keep those parts stocked for exactly this reason.
In Pacifica, it’s the roof and flashing above the header more often than the door itself. Wind pushes rain up under failing roof-to-wall flashing, and it runs down onto the door header. We always check the roof-to-wall detail above the entry first, then work down. Call (855) 473-5620 for an inspection, estimates are free.
Often yes. If the fiberglass slab is sound and square and only the jamb wood and seals have gone, we replace the wet frame components, set a new sill pan, and reseal around the original Therma-Tru slab. That saves a lot of money versus a full door replacement, and the slab typically outlasts two frames in this climate.
Sometimes, especially on bluff-top and Linda Mar homes where wind-driven rain tracks down from the roof line above the entry. If the threshold is wet because the flashing above is failing, you fix the flashing first. We handle roof repair and door work as one scope, so it gets done in one visit, one quote. Call (855) 473-5620 for an exact quote.
