Therma-Tru Construction in Lexington Hills, CA | Moreno Valley Builders
We provide independent Therma-Tru door installation and repair across Lexington Hills, CA, serving homeowners in the 95031 ZIP. What separates our Therma-Tru work here isn’t the door hardware itself but the fact that almost every opening we touch sits on a steep hillside, requires Chapter 7A ignition-resistant detailing, and has to clear Santa Cruz County and fire-district review before the permit closes. Call (877) 752-3154 for a free estimate on a Therma-Tru project in Lexington Hills.
We’re an independent builder, not an authorized Therma-Tru dealer. We stock and install OEM sills, sweeps, hinges, and multi-point hardware, and we know which Therma-Tru models hold up in this fog-belt mountain climate and which ones don’t. Therma-Tru sales & service is part of what we do, but the half of the job that matters most here is the install: a prehung unit set in a racked rough opening on a pier-and-beam foundation will fail within two winters no matter how good the slab is.
Why Lexington Hills Residents Choose Us for Therma-Tru Service
We’ve hung and re-hung Therma-Tru entry, patio, and sidelite systems across the Santa Cruz Mountains for years — including Los Gatos Therma-Tru service calls — so we know how their fiberglass skins, adjustable sills, and multi-point lock hardware behave in fog-belt and fire-hardened assemblies. Noel Trevino, our owner and general contractor, grew up in the Inland Empire and spent the better part of three decades building and renovating homes before Moreno Valley Builders started taking on mountain work like this. He’s the contractor who gets called when a door has gone sideways, literally: a Therma-Tru unit that latches at the top and swings free at the bottom because the hillside moved under the rough opening.
We work in Lexington Hills service area homes ranging from mid-century mountain cabins to CZU Lightning Complex rebuilds, so we’ve seen what happens when a door gets installed without accounting for slope settlement, fog-driven moisture, and fire-review requirements. If the details aren’t right on paper, they won’t be right in the wall. That’s why our paperwork, our shimming, and our flashing all get the same scrutiny before we call a job done.

Common Therma-Tru Construction Problems We Solve in Lexington Hills
- Chalky, oxidized fiberglass skins. South- and west-facing entries in Lexington Hills get hammered when fog burns off into hard afternoon sun. Therma-Tru Fiber-Classic and Smooth-Star finishes dull years before the frame fails. We refinish where the skin is sound and tell you straight when a slab needs replacing.
- Doors that drag or bind every winter. Adjustable sill and sweep seals pack with redwood needles and oak litter, then hold winter rain against the threshold. The failure shows up as a swollen bottom rail or a door that drags in February. It’s a seal and threshold problem, not a slab problem, and the fix is usually OEM parts, not a new door.
- Multi-point locks out of alignment. Hillside pier-and-beam entries in Lexington Hills settle with the slope. Hinge and lock hardware falls out of alignment, so the door latches at the top and hangs open at the bottom. We re-shim and re-hang before we ever talk about replacing hardware.
- Pre-Chapter 7A slabs blocking WUI sign-off. Original builder-grade Therma-Tru doors in older Lexington Hills homes lack ember-resistant edge seals and noncombustible thresholds. When an owner remodels or rebuilds, the door assembly itself can trigger the fire-district correction list.
- Threshold leaks on hillside entries. Winter runoff off the uphill side of a Lexington Hills home can pour against a poorly flashed threshold. We re-flash with raised, back-dammed sill pans so water sheds away from the door instead of into it.
Therma-Tru Service in Lexington Hills: What Local Conditions Mean for Your Equipment
Lexington Hills is unincorporated Santa Cruz County, so a Therma-Tru entry replacement or a new door opening cut during a rebuild has to clear county building review plus fire-district sign-off before the county will close the permit. Because so much of the housing stock here is older and non-conforming, many remodels and rebuilds sit on stepped pier-and-beam foundations cut into slopes, and the door assembly itself can be the item that triggers Chapter 7A ignition-resistant detailing. That’s the part most door installers miss. They’ll set a prehung unit square to the opening on the day of install, but they don’t account for what the slope will do to that opening in five years, or what the fire district inspector will flag when the permit comes up for final review.
We’ve seen it happen on a stepped pier-and-beam cabin off a narrow private lane in Lexington Hills, and on similar Therma-Tru service in Monte Sereno jobs. Our crew opened the wall for a Home Addition and found the original Therma-Tru Fiber-Classic entry hung in a rough opening that had racked a half inch out of plumb as the slope settled. We reframed and shimmed the opening, set a new prehung unit with a raised, back-dammed sill pan and ember-resistant edge seals to satisfy the fire-district review, and re-flashed the threshold so winter runoff off the uphill side sheds away from the door instead of into it. The county signed off, and the door still swings free.
Therma-Tru Models & Products We Service in Lexington Hills
We install and service Therma-Tru Fiber-Classic entry doors, Smooth-Star fiberglass doors, Classic-Craft collection units, and patio and sidelite systems with multi-point locking hardware. We use Therma-Tru OEM sills, sweeps, hinges, and multi-point hardware whenever the door is worth saving, because aftermarket seals rarely match the extrusion profile and leak within a season. When a slab has delaminated or the rough opening has racked, we say so. A re-shim and re-flash beats a new door set into a moving frame, and vice versa.

FAQs – Therma-Tru Construction in Lexington Hills
Does replacing a Therma-Tru front door in Lexington Hills require a Santa Cruz County permit and fire-district review? Yes, in most cases. Because Lexington Hills is unincorporated Santa Cruz County, a door replacement that involves the rough opening, framing, or a new opening cut during a rebuild triggers county building review and fire-district sign-off before the permit closes. We handle that paperwork and the required detailing.
Why does my Therma-Tru door stick at the top and swing free at the bottom every winter? That’s almost always hillside settlement under a pier-and-beam foundation. The rough opening racks, the hinges fall out of alignment, and the door latches at the top while the bottom hangs loose. You don’t need a new door; you need a re-shim and re-hang, and sometimes a reframed opening if the settlement is structural. Call (877) 752-3154 and we’ll tell you which one you’re looking at.
Can a truck deliver a prehung Therma-Tru unit to my private mountain road? It depends on the road. Lexington Hills has narrow, winding private lanes, and some driveways can’t take a full delivery truck. We plan around that before the door ever gets ordered, including staging the unit lower on the road and walking it up if that’s what the site requires.
Will a new Therma-Tru entry door meet Chapter 7A ignition-resistant requirements for a Lexington Hills rebuild? A new Therma-Tru fiberglass door can meet Chapter 7A, but only if it’s specified with ember-resistant edge seals, a noncombustible threshold, and proper flashing. We order and install those details up front so the fire-district review doesn’t bounce the permit back to you.
My Therma-Tru fiberglass door finish is chalky and dull after a few seasons – does it need replacing? Usually not. Chalking on south- and west-facing Lexington Hills entries is a finish failure, not a structural one. We assess the skin, and if it’s sound we refinish it. If it’s delaminated or the core is compromised, then replacement is the honest call. Call (877) 752-3154 for an exact assessment and a free estimate on either path.
