Therma-Tru Construction in Woodside, CA | Iron Beam Contractors
Iron Beam Contractors provides independent Therma-Tru door and window installation, repair, and full rough-opening rebuilds across Woodside’s estate lots and private lanes. We are not a Therma-Tru dealer or authorized service center. What sets our work in Woodside apart is simple: we sequence every door and window package around the town’s tree-protection review, WUI fire-safe standards, and private-road access limits before we ever order a slab. Call (833) 756-5936 to schedule a free site assessment.
Why Woodside Residents Choose Us for Therma-Tru Service
Most contractors can hang a pre-hung door. Fewer can tell you why a west-facing Fiber-Classic slab checks along the lower rail in three years on a Woodside estate with zero porch overhang, or why a hinge-side jamb binds every February on a hillside parcel with pier-and-post framing. We can, because we’ve fixed enough of both. Nolan Driscoll, our owner, learned structural fundamentals through the Building and Construction Technology program at Santiago Canyon College and spent two decades framing, pouring, and reinforcing before he built Iron Beam Contractors. That background matters when a Therma-Tru entry needs more than a slab swap. We bring full Therma-Tru sales & service knowledge to every job, and since we also handle interior remodeling, roofing, and hardscape under one contract, you’re not juggling a door crew and a stucco crew and a roofer to get one opening right. One contractor, every phase.

Common Therma-Tru Construction Problems We Solve in Woodside
- Fiberglass finish checking and fading on exposed entries. Woodside’s Mediterranean sun hits west- and south-facing doors hard, especially on older estates where a shallow porch or no overhang at all leaves the slab fully exposed. Therma-Tru’s fiberglass holds up better than wood, but the finish still breaks down when UV and heat cycle the surface daily. We refinish where the substrate is sound and replace where the skin has cracked through.
- Sill and threshold rot from slope-driven runoff. Winter rain sheets off sloped driveways on Woodside’s hillside lots and ponds at the entry. If the original sill pan was flashed wrong or never installed, water sits at the threshold and rot follows within a few seasons. We don’t patch a rotted jamb. We cut it out, rebuild the rough opening, and set a proper sill pan before the new Therma-Tru slab goes in.
- Weatherstrip and sweep failure opening ember-entry gaps. On WUI-designated parcels, the door assembly is part of the ignition-resistant envelope. A worn sweep or flattened weatherstrip on a Therma-Tru entry is not just a draft problem in fire season. We replace sweeps and compression seals with ember-resistant profiling and make sure the door seals tight against the frame, not just against the stop.
- Jamb swelling and seasonal binding on slope-adjacent entries. Woodside’s clay expands and contracts with winter saturation. Pier-and-post entries and homes on cut slopes move enough over a wet season that a door that was plumb in September drags on the latch stile by February. We diagnose whether the slab is out of square, the frame has shifted, or the foundation has moved, and we fix the cause before the symptom.
- Out-of-square rough openings from original estate construction. A lot of Woodside’s mid-century and early custom homes were framed tight and fast. When we pull an old Therma-Tru unit, the rough opening is often 1/4 inch out of square or the header has settled. Hanging a new slab over a bad frame guarantees the same problem returns. We rebuild the opening to spec, then set the door.
Therma-Tru Service in Woodside: What Local Conditions Mean for Your Equipment
Woodside’s private lanes and shared driveways are reviewed for fire-truck turnaround and access before permits ever issue, and that same review shapes how a Therma-Tru door package reaches your home. On estate parcels off narrow private lanes, a full-size delivery truck often cannot make the final turn or back up to the garage, so we stage slabs and glass at the front gate and shuttle them in by hand or with a small utility vehicle. That extra step is not an inconvenience we work around. It’s part of why we inspect every Therma-Tru unit for freight damage before it leaves the gate. A door that gets dropped at the curb and rolled up a gravel drive in a dolly picks up chips on the hinge stile and hairline cracks in a fiberglass skin that no finish will hide. We’d rather carry it once, correctly, than explain a warranty denial on a slab that was damaged before it ever touched the opening.
Therma-Tru Models & Products We Service in Woodside
We install and service the full residential Therma-Tru line that matters in Woodside’s estate market: the Fiber-Classic entry series for traditional and custom profiles, Smooth-Star for cleaner contemporary elevations, Classic-Craft for high-detail grain and panel work, and hinged patio and French door systems where indoor-outdoor flow is the point of the whole design. On the parts side, we use Therma-Tru OEM slabs, sills, and multi-point hardware wherever the existing frame is sound. Where OEM weatherstrip and sweep kits add weeks of lead time, we spec quality aftermarket equivalents that meet or exceed the original compression rating. But we never patch a rotted jamb or failed sill pan and call it a repair. On a Woodside entry, that’s a moisture and ember problem waiting to return. If the rough opening is out of square or the flashing was never done right, we rebuild the opening rather than hang a new slab over a bad frame. If the structure makes sense on paper, it’ll hold in the field. If it doesn’t make sense on paper, we fix it before we touch a beam.

AfterTherma-Tru Service Pricing in Woodside
Because we run Therma-Tru work through the same full-scope Woodside General Contractor operation that handles kitchens, baths, and additions, our pricing reflects the actual scope on your opening, not a flat door-hanging fee. Below are the project ranges we most often quote for Therma-Tru-adjacent work in the 94062 zip code:
| Project | Typical Range in Woodside |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Home Addition (door/window scope included) | $45,000 – $130,000 |
What drives the number in Woodside is almost always access and opening condition, not the door itself. A pre-hung Therma-Tru replacement on a flat, code-sound opening is a day of work. A sloped entry with a failed sill pan, WUI detailing, and a private-lane staging plan is a different project. Call (833) 756-5936 and we’ll walk the opening with you and give you a written line-item quote. Estimates are free.

FAQs – Therma-Tru Construction in Woodside
Yes, in most cases on WUI-designated parcels, replacing an exterior entry door falls under the town’s fire-safe construction standards and may require the replacement assembly to meet ignition-resistant or ember-resistant detailing requirements. We scope the door and frame details against the current WUI checklist before you order anything, so you don’t get a correction notice mid-permit. Call (833) 756-5936 and we’ll tell you what your parcel actually triggers.
Often not, and that’s the planning point most homeowners miss. Woodside’s private lanes and shared driveways are reviewed for fire-truck turnaround and access, and a full-size freight truck may be longer than what the lane will pass. We stage Therma-Tru slabs and glass at the gate and bring them up by hand or small vehicle, inspecting every unit for freight damage before it leaves the gate. Call (833) 756-5936 and we’ll assess your lane before you order.
Because Woodside’s clay soils expand when saturated, and pier-and-post or slope-adjacent entries move just enough over a wet season that a door plumb in September drags by February. The slab may be fine. The frame has shifted. We check the rough opening, the hinge-side jamb, and the foundation line before recommending a planer pass, a re-shim, or a structural fix. Call (833) 756-5936 for a binding assessment.
Only if the problem is the door. If water ponds at your threshold because the drive grades toward the entry and the original sill pan was flashed wrong, a new slab just moves the leak to the new frame. We rebuild the rough opening with a proper sill pan, re-flash the opening, and set the new Therma-Tru unit so water sheds away from the assembly. Call (833) 756-5936 and we’ll show you what’s actually happening at the threshold.
Yes. Any opening change on a Woodside parcel can trigger tree-protection and planning review when a heritage oak or protected tree sits near the work area. We coordinate tree surveys and WUI defensible-space plans before design is finalized, so a door or window replacement doesn’t stall at permit because nobody checked the dripline. Call (833) 756-5936 and we’ll sequence the review correctly from the start.
