Therma-Tru Construction in Broadmoor, CA | Iron Beam Contractors
We install, flash, and repair Therma-Tru entry and patio door systems across Broadmoor, CA, and the one thing that separates our work here is how we handle the greenbelt. Mature Monterey cypress and pine roots lift and rack the concrete stoops and thresholds in front of so many 1940s and 50s Broadmoor homes that a door replacement here usually starts with the rough opening, not the slab. We’re a Broadmoor General Contractor, not a Therma-Tru affiliate, and we stock genuine Therma-Tru slabs, sill pans, and weatherstrip for fast local turnaround. Call (833) 756-5936 to schedule a free estimate.
Why Broadmoor Residents Choose Us for Therma-Tru Service
Therma-Tru builds a fiberglass door that can outlast the framing around it. The slab is rarely the problem. What fails in Broadmoor is the installation detail: the sill pan that was never flashed, the brickmold that lets fog moisture sit behind the jamb, the rough opening that tree roots have racked out of square. Nolan Driscoll started Iron Beam Contractors with a rule he learned framing and pouring across Orange County: tell the homeowner what’s in the wall before you open it, not after. That matters on greenbelt lots where a door replacement can turn into a stoop reset and a tree-protection plan before the first screw comes out.
We approach Therma-Tru work the way a structural contractor should. The door is part of the building envelope, not a standalone fixture. That’s why our Therma-Tru sales & service work always includes a check of the flashing, the rough opening, and the substrate before we hang anything.

Common Therma-Tru Construction Problems We Solve in Broadmoor
- Sill and threshold rot from fog-driven moisture. Broadmoor’s wind-driven Pacific moisture and fog condensation pool against entry sills that were never pan-flashed. We routinely pull a Therma-Tru slab and find the sill system rotted through while the fiberglass skin is still perfectly fine.
- Finish cracking and peeling on south and west elevations. Sun exposure combined with fog dampness breaks down the finish on Therma-Tru doors where 1940s and 50s stucco walls and shallow original detailing let water sit behind the brickmold. We strip, re-seal, and re-flash these before they spread into the jamb.
- Hinge-side jamb and frame rot from seasonal soil movement. Greenbelt roots and seasonal soil heave rack the rough opening out of square on older Broadmoor homes. The Therma-Tru door drags, the weatherstrip seal fails, and moisture gets in. We re-square the opening before we hang the new slab.
- Fogged glass lites and failed glazing seals. Constant marine-layer humidity gets behind the insulated glass unit on Therma-Tru entry and patio doors. We replace the lite and upgrade the seal rather than selling you a full door replacement when the slab is sound.
- Hardware corrosion from salt-laden fog. Cheap fasteners and hinges corrode fast in Broadmoor air. We replace them with marine-grade stainless and reset the door geometry at the same time.
Therma-Tru Service in Broadmoor: What Local Conditions Mean for Your Equipment
Broadmoor is the only Daly City neighborhood where nearly every lot touches a 1920s Olmsted-planned greenbelt, and that greenbelt changes how Therma-Tru doors have to be installed. The mature Monterey cypress and pine trees that line the greenbelt send roots under sidewalks, stoops, and foundation edges. On greenbelt-backing lots, those roots lift concrete thresholds and rack the rough opening, so a Therma-Tru entry replacement in Broadmoor starts with re-setting the stoop and re-squaring the frame before the new door can be hung and flashed correctly. Any excavation near the greenbelt can require an arborist report and a city-approved tree protection plan, which adds a step you won’t find in most of Daly City or South San Francisco Therma-Tru service areas. We plan for that from the first site visit, so the door goes in clean and the permit doesn’t stall the job.
On a greenbelt-backing lot near the Broadmoor Golf Course, a homeowner called us because their Therma-Tru Classic-Craft entry door had started sticking and the threshold was spongy. We hand-carried the replacement slab and sill pan down the shared driveway past the tree-protection zone, pulled the door, and found the original sill rotted through and the fiberglass skin cracked at the brickmold. The roots from an adjacent cypress had lifted the stoop and racked the opening. We reset the threshold pan, re-squared the jamb, re-flashed it, and hung a new Classic-Craft slab with upgraded weatherstrip, delivering Therma-Tru repair in Colma and nearby Broadmoor with the same care. The door now closes clean even through the foggy months.
Therma-Tru Models & Products We Service in Broadmoor
We service the full Therma-Tru lineup that shows up in Broadmoor homes: Classic-Craft American Style entry doors, the Fiber-Classic collection, Smooth-Star fiberglass doors, and Fiber-Classic patio and sliding-glass door systems. When the door skin and frame profile are still sound, we spec genuine Therma-Tru replacement slabs, sill pans, weatherstrip, and hardware. When the OEM detail is the weak link in a coastal exposure, we reach for quality aftermarket thresholds and marine-grade stainless fasteners. If the sill and jamb have already rotted through, we tell you straight that a full prehung replacement is the right call rather than patching a door that fails again next winter.

FAQs – Therma-Tru Construction in Broadmoor
Yes, if the work involves excavation, stoop removal, or any ground disturbance within the greenbelt’s protected zone. Broadmoor’s Olmsted-planned greenbelt runs through nearly every lot edge, and the city can require an arborist report and tree-protection plan before we reset a threshold or dig near mature cypress and pine roots. We confirm the requirement during the estimate and handle the paperwork. Call (833) 756-5936 to get the process started.
In Broadmoor it’s usually the rough opening, not the door. Greenbelt roots and seasonal soil movement rack the frame out of square, so the slab drags no matter how many times the hinges are adjusted. The fix is re-squaring the opening and re-hanging the door, sometimes with a stoop reset first. Call (833) 756-5936 and we’ll tell you whether it’s a hardware adjustment or a structural fix.
No. A fogged lite means the insulated glass unit has failed and moisture is trapped inside. We replace the lite and reseal the glazing without replacing the slab or frame, as long as the door itself is sound. Call (833) 756-5936 for a free look at what’s actually failed.
Usually yes. Broadmoor’s tightly packed 1940s and 50s lots often have rear additions and in-law units that trigger structural upgrades and Title 24 compliance when you touch the building envelope. A new entry door on an addition means the rough opening, flashing, and sometimes the adjacent wall framing have to meet current code. We pull permits and coordinate the inspection before, during, and after the door goes in. Call (833) 756-5936 to talk through your specific addition.
No. Iron Beam Contractors is an independent general contractor. We install, repair, and replace Therma-Tru doors using genuine Therma-Tru parts, but we are not affiliated with or endorsed by Therma-Tru. That independence means we spec the right fix for Broadmoor conditions, not a manufacturer’s recommended patch.
