We also handle Therma-Tru repair in Daly City for homes near the Broadmoor border. What sets our Therma-Tru work apart in Broadmoor is knowing exactly how these doors fail on this side of the Peninsula and fixing them so they don’t fail again in three years.

Why Broadmoor Residents Choose Us for Therma-Tru Service
Therma-Tru entry doors are not generic slabs you can trust to a framing crew that happens to be on site. Their fiberglass construction flexes differently than steel or wood, the sill pans and weatherstripping are engineered to specific tolerances, and a door set half an inch out of plumb on a Broadmoor stucco wall will bind within a season. Our crew has pulled apart enough Therma-Tru Smooth-Star and Fiber-Classic doors on these tightly packed post-war homes to know exactly where each generation gives out.
Nelson Fung, our owner and Broadmoor General Contractor, learned the trade at Los Angeles Trade-Technical College and spent years on remodels before starting Timberline Contractors. He’s the kind of contractor who will tell you when a repair makes sense and when you’re throwing good money at a door that should have been replaced a decade ago. We work the way Broadmoor homes actually need us to: close lot lines, stucco returns, and a marine climate that punishes shortcuts.
We’re an independent contractor. We buy Therma-Tru product, install it correctly, and stand behind our workmanship. We are not authorized, sponsored, or warranted by Therma-Tru, and we’ll never imply otherwise.

Common Therma-Tru Construction Problems We Solve in Broadmoor
- Bottom rail and sill rot from marine fog. The persistent moisture that rolls through Broadmoor attacks the bottom rail of Therma-Tru fiberglass doors where the finish has blistered, then wicks up behind the frame where caulk has failed against stucco. We see this on nearly half the older Therma-Tru installs we inspect in 94015.
- Door sweeps and weatherstripping flattened by wind-driven drizzle. On Broadmoor’s side-by-side lots, prevailing wind pushes rain hard against door faces that barely dry between storms. The weatherstrip compresses, the sweep tears, and suddenly you feel a draft at the jamb and see condensation inside the threshold on foggy mornings.
- Multipoint hardware corrosion on patio and French doors. Salt-laden air reaches the strike plates, hinges, and fasteners faster than inland installs. The hardware seizes or corrodes at the screw points, the door sags, and it starts dragging across the sill every time you open it.
- Frame and sill rot where the original installer skipped a pan flashing. Older Therma-Tru installs in Broadmoor often have the door butted directly against wood framing with no proper pan flashing underneath. Damp wood wicks water straight up the jambs, and by the time you see the stain inside, the framing is already soft.
- Stucco returns cracked around door openings. The transition between a Therma-Tru frame and the dense stucco cladding on Broadmoor’s mid-century homes fails over time as the building settles and the marine air works into hairline cracks. Water follows, and the seal around the door eventually breaks.
Therma-Tru Service in Broadmoor: What Local Conditions Mean for Your Equipment
Broadmoor is a small unincorporated pocket of San Mateo County that sits functionally inside Daly City, the last residential stop before San Francisco’s southern edge. For homes just west of here, we also provide Therma-Tru service in Pacifica. That means the Therma-Tru door on your Broadmoor home lives in a marine climate where fog and salt air shape every exterior detail, and it also sits in a county-island permit context that most neighboring cities don’t share. When a door swap touches structural framing, we confirm whether the project falls under San Mateo County permitting and inspection rather than Daly City’s. That’s not a bureaucratic footnote. County inspectors on this side of the hill care about specific flashing details, sill pan requirements, and stucco integration at door openings, and we’ve done enough of these to know what they’ll flag before they flag it.
On a mid-century stucco-over-wood home near the Broadmoor/Daly City line off ZIP 94015, our tech pulled a Therma-Tru Fiber-Classic entry door whose bottom rail had blistered and whose threshold had rotted from years of wind-driven fog moisture. We cut back the soft framing, reframed and set a proper pan flashing, and installed a new OEM sill and sweep with a fresh stucco return tight to the neighboring wall so the door finally sealed against the wind. The homeowner reported the entryway draft and interior condensation stopped that same week.
Therma-Tru Models & Products We Service in Broadmoor
We work on the full Therma-Tru range that shows up in Broadmoor homes: Smooth-Star fiberglass entry doors, the Fiber-Classic collection, and the Classic-Craft series with its wood-grain detail. We also service Therma-Tru patio and French door systems, including the OEM sills and multipoint hardware that fail so predictably in salt air.
Our parts approach is straightforward. We use genuine Therma-Tru OEM sills, sweeps, weatherstripping, and multipoint hardware so the door’s seal and operation stay within the manufacturer’s design. Aftermarket seals are cheaper up front, but they flatten and crack fast in this marine climate, and then you’re paying for the same repair twice. We keep the most common Broadmoor-failure parts on hand so most entry door repairs happen in one visit, not two.

FAQs – Therma-Tru Construction in Broadmoor
We start by properly flashing the rough opening with a pan flashing under the sill that slopes to the exterior, then we set the door plumb and square regardless of what the neighboring wall is doing. For tight side-by-side Broadmoor lots, we also make sure the exterior casing and any stucco return shed water away from the jamb rather than channeling it behind the frame. If there’s a shared fence or wall within a few inches, we’ll typically use a deeper jamb extension so the door seals fully without a compromised weatherstrip gap. Call (866) 253-5808 for an exact assessment of your lot’s constraints.
No. Timberline Contractors is an independent general contractor, not a Therma-Tru factory-authorized dealer or service provider. What we bring is hands-on experience with Therma-Tru product lines, OEM parts sources, and the specific failure modes these doors develop on Broadmoor’s foggy, salt-exposed streets.
We use genuine Therma-Tru OEM sills, sweeps, weatherstrip, and multipoint hardware. Aftermarket seals are widely available, but in this marine climate they fail fast. We won’t install a part we know will send you back to the phone in twelve months.
A straight door slab swap on sound framing usually takes one day. If the threshold or lower framing is rotted from years of fog moisture, we reframe and rebuild before setting the new unit, which can extend the job to two or three days including the stucco return and any permit inspection timeline.
We service Smooth-Star fiberglass entry doors, the Fiber-Classic collection, Classic-Craft door series, and Therma-Tru patio and French door systems with OEM sills and multipoint hardware. If you have an older Therma-Tru unit we didn’t name, call (866) 253-5808 and describe the door. We’ll tell you honestly whether it’s worth repairing.
A dragging door usually needs hinge and threshold adjustment, or a new multipoint lock if the hardware has seized from salt air. Those repairs typically fall in the lower end of our window and door pricing, around $400 to $1,800 depending on parts. If the slab is rotted and we’re replacing the door, expect $4,500 to $15,000 for a proper window and door replacement scope. Call (866) 253-5808 and we’ll give you a free written estimate before anything happens.
