What makes our work different here is simple: we flash and hang doors for Burlingame’s actual conditions, not a showroom spec.

Why Burlingame Residents Choose Us for Therma-Tru Service
We’ve spent years setting, re-hanging, and re-flashing Therma-Tru entry and patio systems on Burlingame’s old wood-frame homes. We know where fiberglass skins, sill pans, and hinge plates actually fail on this side of the Peninsula because we see it weekly. That’s the difference between reading a parts catalog and walking into a 1930s bungalow near Burlingame Avenue with a sagging header.
Norm Castellano runs our crew, and he’s the guy people call when a previous contractor left a mess that needs untangling. He grew up around houses that were always mid-project and went through San Bernardino Valley College’s construction technology program before spending nearly two decades on framing, roofing, and full interior rebuilds. His crew now handles Therma-Tru sales & service the way he handles every trade: find the actual failure, fix it once, use the right parts.
We’re an independent contractor. Not authorized, sponsored, or warranty-backed by Therma-Tru. We say that up front so you know exactly whose workmanship you’re paying for.

Common Therma-Tru Construction Problems We Solve in Burlingame
- Bottom-rail and sill rot on Fiber-Classic and Smooth-Star slabs. Burlingame’s fog keeps door faces damp, and on older homes near downtown the original thresholds sit under shallow porch overhangs that shed almost no water. The wood sill core wicks moisture up, the bottom rail softens, and the door eventually sags. We test with a probe before recommending repair or replacement.
- Racked doors on century-old Craftsman and Spanish bungalows. A hundred years of settling has moved headers on homes around Burlingame Avenue. A new pre-hung unit binds at the top corner before the weatherstrip ever seats. We re-shim, adjust strike plates, and when the rough opening is too far gone, we frame it square before hanging the door.
- Yellowed or chalked fiberglass skins on east- and west-facing ranch homes. In the Burlingame Hills and Mills Estate, afternoon sun and winter moisture blister paint at the bottom rail. The fiberglass itself can usually be refinished, but the failure often starts where stucco meets the sill. We address both.
- Hinge sag and strike misalignment after seismic jolts. The Peninsula shakes, stucco cracks, and water gets into the rough opening. The shim pack loosens, the slab drops, and suddenly the deadbolt won’t throw. This is one of the most common calls we get in 94010.
- Failed patio door sills on hillside lots. On steep Burlingame Hills properties, runoff drains straight toward back doors. When the sill pan isn’t flashed up the jambs, groundwater washes it every winter and the slab rots from the bottom rail up.
Therma-Tru Service in Burlingame: What Local Conditions Mean for Your Equipment
Burlingame sits directly under the SFO flight path, and that fact shapes more door replacements here than most homeowners realize. When an exterior door or window opening is part of a remodel, the project often gets pulled into SFO-related height and noise review alongside Burlingame’s residential design guidelines. That means a Therma-Tru entry or patio door spec can be questioned on assembly and glazing performance, not just looks, before a permit clears. In the Mills Estate and Burlingame Hills, where dozens of 1950s ranch homes were built on steep, unretained lots, remodels also uncover original hillside drainage and foundation issues that trigger geotechnical review. A door that gets blamed for bad fiberglass is frequently the victim of bad drainage. On one Mills Estate ranch cut into a hillside, we pulled a Smooth-Star patio door that had rotted through the bottom rail and found the threshold buried below grade. Groundwater had been washing the sill pan every winter. We reset the opening on a raised treated sill, flashed up the jambs, re-graded the box drain, and only then hung the new pre-hung unit. The door wasn’t the problem. The site was.
Therma-Tru Models & Products We Service in Burlingame
We service the full Therma-Tru fiberglass line: Fiber-Classic and Smooth-Star entry doors, Classic-Craft entry systems, fiberglass patio and hinged patio doors, and fire-rated entry door assemblies. On the parts side, we use OEM Therma-Tru replacement sills, weatherstrip kits, and hinge sets where the slab and frame are still sound. Aftermarket sills and seals are where leaks start, so we don’t spec them. When a fiberglass skin is cracked through or the wood bottom rail is soft to the probe, we recommend a full pre-hung replacement rather than a patch. A repair that only skins over rot fails again after the first wet winter, and Burlingame will definitely deliver one.

AfterTherma-Tru Service Pricing in Burlingame
Door work doesn’t always mean buying a new door. A hinge reset, weatherstrip replacement, or sill pan re-flash is often a few hundred dollars. A full pre-hung entry or patio replacement on an older Burlingame home typically lands somewhere in the window replacement range because the rough opening usually needs correction work. Here are the ranges we quote most often when a Therma-Tru job ties into a larger scope:
| Service | Price Range |
|---|---|
| Impact Window Installation | $8,000 – $25,000 |
| Window Replacement | $4,500 – $15,000 |
| Full Kitchen Remodeling | $14,000 – $45,000 |
| Full Bathroom Remodeling | $9,000 – $28,000 |
| Roof Repair | $400 – $1,800 |
Your free estimate includes us looking at the rough opening, the sill pan, the flashing, and the drainage around the door. Not just the panel. Call (855) 382-3257 and we’ll give you a written line-item quote.

FAQs – Therma-Tru Construction in Burlingame
No. We’re an independent contractor that installs and services Therma-Tru door systems. We’re not authorized, sponsored, or warranty-backed by Therma-Tru. What you get from us is direct accountability for our own workmanship, and we use OEM parts so the door itself keeps whatever factory coverage it has.
We use OEM Therma-Tru replacement sills, weatherstrip kits, and hinge sets whenever the slab and frame justify repair. Aftermarket sills and seals are where leaks start, so we don’t install them. If the fiberglass skin is cracked through or the bottom rail is soft, we recommend replacing the unit rather than covering a structural failure.
Most hinge resets, weatherstrip replacements, and sill repairs take half a day on site. A full pre-hung replacement on an older Burlingame home usually takes one to two days, depending on what we find in the rough opening and whether permit review applies. Call (855) 382-3257 and we’ll give you a straight timeline for your specific door.
We service Fiber-Classic and Smooth-Star entry doors, Classic-Craft entry systems, fiberglass patio and hinged patio doors, and fire-rated entry assemblies. If it’s a Therma-Tru fiberglass door in Burlingame, we’ve likely re-hung or re-flashed one like it in the last month.
A straightforward hinge or weatherstrip repair typically runs in the low hundreds. A full pre-hung replacement, especially on an older home where the rough opening needs correction, usually falls between $4,500 and $15,000 depending on scope. The exact number depends on what’s behind the trim. Call (855) 382-3257 for a free estimate and we’ll break it down line by line.
