Therma-Tru Construction in Felton, CA | Iron Beam Contractors
We provide independent Therma-Tru door installation, repair, and replacement across Felton, CA (95018). The thing that separates our Therma-Tru work in Felton from flatland crews isn’t brand access, it’s that we know these doors fail here from shade and moisture, not sun. That changes how we prep, flash, and finish every single door we touch. Call (833) 756-5936 for an honest assessment of your door.
Why Felton Residents Choose Us for Therma-Tru Service
Most door contractors in the San Lorenzo Valley treat Therma-Tru like any other pre-hung unit. We don’t. We’ve pulled apart enough of their fiberglass and steel lines on sloped Felton lots to know exactly where they rot, where they leak, and what holds up through a real winter storm cycle. Nolan Driscoll, our owner, has spent his entire construction career working sites where drainage and moisture kill doors faster than anything else. That’s the lens we bring to every Therma-Tru repair in Mount Hermon and throughout Felton.
We’re an independent service provider, not a factory warranty station. That means we stock OEM hinges, locksets, and weatherstripping for Therma-Tru sales & service turnaround, but we won’t sell you a factory part when a better aftermarket sill handles Felton’s runoff properly. The goal is a door that opens and closes in ten years without a crowbar. Most of our Felton clients call us because a previous install either wasn’t flashed right or the wrong finish got slapped on a shaded entry.

Common Therma-Tru Construction Problems We Solve in Felton
- Bottom rail rot from winter runoff. On Felton’s steep lots, stormwater splashes up against the door base, wicks into the jamb, and sits there in the redwood shade. We see bottom rails that look fine from the outside but turn to sponge when you pull the weatherstrip. Replacement with a positively sloped sill and proper under-threshold flashing is the fix, not caulk.
- Fiberglass skin delamination on shaded entries. Therma-Tru fiberglass doors on north-facing or deep-overhang Felton homes fail from chronic damp, not UV. The finish never fully cures, moisture works under the skin, and the face starts lifting. We strip, prep with a moisture-tolerant primer, and refinish with marine-grade topcoats rated for exactly this condition.
- Wood-edge jamb and brickmold rot. High rainfall plus minimal sun means wood components around Therma-Tru doors in Felton rot in five to seven years on unprotected entries. We replace with composite brickmold and re-flash the rough opening so the new material doesn’t sit in a puddle.
- Threshold failures that let embers and water in. Felton sits inside wildland-urban interface zones. A cracked or sunken threshold on a Therma-Tru door isn’t just a draft problem, it’s a fire-hardening failure. We inspect and replace thresholds with ember-resistant seals that meet Chapter 7A expectations on replacement doors.
- Steel door dents and corrosion at the bottom rail. Clogged hillside drainage sends water and gravel against steel Therma-Tru doors on sloped lots. We fix it, but we also fix the grade or drainage so it doesn’t come back next winter. A door repair without a drainage fix on a Felton slope is repeat business, and that’s not the kind we want.
Therma-Tru Service in Felton: What Local Conditions Mean for Your Equipment
Here’s the thing most out-of-town door guys don’t grasp about Felton. Your Therma-Tru door isn’t baking in sun. It’s sitting in shade under a redwood canopy or a deep overhang for most of the day, even in summer. Winter storms drive rain horizontally against it. The result is a door that never truly dries out. Finishes that perform fine on a south-facing San Jose entry will chalk, crack, or lift within a few years on a shaded Felton entry because the prep and cure conditions are completely different.
On a steep lot off Hihn Street, our crew replaced a failing Therma-Tru Fiber-Classic entry door where the bottom rail had rotted from years of winter runoff wicking up the jamb. We re-flashed the threshold, installed a new OEM sill with a positive slope, and finished the door with a marine-grade topcoat to handle the shaded damp, then added a French drain to divert roof runoff away from the entry. That’s the difference between a door that lasts and one that becomes a maintenance headache every January. If you’re anywhere in the Felton service area with a door that faces a hill or sits under trees, this applies to you.
Therma-Tru Models & Products We Service in Felton
We work on the full Therma-Tru residential lineup: Fiber-Classic, Smooth-Star, Classic-Craft, and the Pulse line. Most of what we see in Felton is Fiber-Classic and Smooth-Star, which makes sense given the price point and the fact that half this valley treats doors as a utility, not a statement piece, until they stop closing. We also handle Therma-Tru repair in Ben Lomond with the same approach.
For repairs, we use OEM hinges, locksets, and weatherstripping to preserve the original fit and hardware preps. Sills and thresholds are a different conversation. We source aftermarket aluminum and composite sills with better drainage geometry for Felton’s rain loads when they outperform OEM. We carry common Therma-Tru hinge and weatherstrip sets locally, so most Felton service calls don’t wait on a parts order.
Therma-Tru Service Pricing in Felton
Door work in Felton is priced by scope, not by a flat menu. A slab swap is different from a full frame replacement with rot repair and re-flashing. Here’s how specific projects land:
| Project | Typical Range |
|---|---|
| Window Replacement (per door unit) | $4,500 – $15,000 |
| Roof Repair (storm damage around entry) | $400 – $1,800 |
| Kitchen Remodel (full) | $14,000 – $45,000 |
What drives cost on a Therma-Tru replacement in Felton is usually hidden: rotted rough opening, undersized drainage, or a non-permitted past addition that left the entry out of square. Our free estimate walks the whole opening and gives you a written, line-item scope before we touch anything. 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. Call (833) 756-5936 for a straight number.

FAQs – Therma-Tru Construction in Felton
A like-for-like door replacement typically doesn’t require a Santa Cruz County permit, but any change to the rough opening, structural header, or adjacent siding often does. We handle permit determination as part of the estimate and pull permits when the scope calls for it.
Felton properties in WUI zones need entry doors with ember-resistant weatherstripping, non-combustible thresholds, and proper perimeter seals. Some Therma-Tru models are better suited for this than others, and we spec accordingly on any replacement inside defensible-space boundaries. Call (833) 756-5936 for a WUI-aware door consult.
Felton’s redwood shade and winter rainfall keep door surfaces damp for months. Fiberglass skins hold up to UV, but constant moisture without drying cycles leads to finish breakdown and delamination. Same door, same finish, wildly different lifecycle between a sunny San Jose lot and a shaded Felton hillside.
Sometimes. If the slab is sound and the rot is confined to the frame or threshold area, we can replace the sill, re-flash, and refinish. If the slab itself is swollen or delaminated at the base, replacement is usually cheaper than a patch job that fails in two winters. Call (833) 756-5936 and we’ll tell you which one you have.
We stage materials at the nearest accessible point and hand-carry to the entry. For tight hillside approaches, we pre-hang in a controlled area and walk the assembly in as a unit. It’s slower, but the doors land square and the finish doesn’t get scratched on a switchback.
Full-Scope Remodeling with Therma-Tru at the Entry
Most Felton homeowners calling about a Therma-Tru door are also looking at what’s behind it. A new entry on a house with a tired kitchen or a leaking roof is half a project. Since Iron Beam handles full kitchen remodeling, bathroom remodeling, and roof replacement under one contract, we can sequence the work so the door, the roofline, and the interior all come together without three different crews tripping over each other. One Felton General Contractor, every phase. From blueprint to backyard.
