Therma-Tru Construction in Pomona, CA
We install and repair Therma-Tru doors across Pomona’s postwar stucco tract stock and older Craftsman homes, so we understand how fiberglass and steel slabs behave under real Inland Valley heat and wind loading. We’re an independent door and construction outfit, not affiliated with or authorized by Therma-Tru, and we tell homeowners plainly when a slab is worth saving and when it isn’t. Our crew knows Pomona’s housing stock from the 1940s tract homes near Lincoln Avenue to the foothill rebuilds near Phillips Ranch. Call (877) 752-3951 for a free estimate.
Why Pomona Residents Choose Us for Therma-Tru Service
While Ontario Therma-Tru service options vary, most contractors in Pomona swap doors and move on. We don’t. A Therma-Tru Classic-Craft on a west-facing Phillips Ranch entry takes years of direct sun and Santa Ana wind before the finish starts failing, and by then the frame, threshold, and weatherstripping have usually shifted too. We approach every door as a full system: slab, frame, sill, flashing, and the stucco junction where moisture creeps in. If the slab is structurally sound, we rebuild around it with Therma-Tru OEM hinges, sweeps, and weatherstripping. If it’s cracked, delaminated, or the frame is rotted through, we quote replacement rather than patch a door that’ll fail again next summer.
Noel Carranza leads our team, and he grew up around construction in Orange County, working through every phase of residential and commercial builds before starting Sundance Contractors. He’ll walk you through what your door actually needs, not what’s easiest for us to sell. As he puts it, do it right the first time, the second time costs twice as much and nobody’s happy about it. For broader Therma-Tru sales & service, we cover the full scope from product selection to final trim.

Common Therma-Tru Construction Problems We Solve in Pomona
- Sun-faded and chalked fiberglass finishes. South- and west-facing entries in Pomona take relentless afternoon heat, often 95°F and climbing in July. Factory finishes on Therma-Tru Smooth-Star and Classic-Craft slabs oxidize and dull, especially where stucco reflects heat back onto the lower panel. We refinish or replace, depending on how far the chalk has worked into the substrate.
- Rotted wood frames and sills at the stucco junction. 1940s to 1960s stucco-over-wood-frame tract homes in Pomona don’t always have modern flashing details. Moisture wicks into the frame at grade, the sill swells, the slab sticks, and eventually the corner jamb rots through. We cut out the bad wood, reset the frame, and install new flashing before mounting the slab.
- Loose hinges, sagging slabs, and drafts from Santa Ana wind cycling. Strong Santa Ana winds rattle doors on the foothill side of Pomona, working hinge screws loose and compressing weatherstripping unevenly. A door that sealed fine in February drafts by October. We re-shim, re-hang, and replace compressed OEM weatherstripping before it warps the slab’s alignment.
- Leaking seals and flashing on post-2008 Triangle Fire rebuilds. In southwest Pomona neighborhoods like Phillips Ranch, homes rebuilt after the 2008 fire carry newer WUI-era flashing and weatherproofing standards, but older stucco tract homes next door don’t. When a new Therma-Tru entry goes into an older frame, the old flashing almost always needs correction or the door leaks within a year.
- Thresholds that heave and shift. Pomona’s dry heat and cool nights cause concrete stoops and slabs to expand and contract. Over a decade or two, that movement travels into the threshold and knocks the door out of square. A binding or dragging slab is often a threshold issue, not a door problem.
Therma-Tru Service in Pomona: What Local Conditions Mean for Your Equipment
Pomona sits at the foot of the San Gabriel Mountains, and the housing stock is a collision of postwar tract construction and the hot, dry Santa Ana corridor that funneled the 2008 Triangle Complex fire into the city’s southwest hills. Every remodel here has to reconcile old balloon-frame or early platform-frame houses with current WUI and Title 24 energy rules, and that’s different from flat, coastal L.A. or the Inland Empire’s newer master plans. For a Therma-Tru entry, that means the door plane and flashing on a fire-hardened rebuild near Phillips Ranch won’t match the older stucco tract house next door. An installer who’s only worked new-construction subdivisions won’t anticipate the tolerance mismatch. We do, every time. That’s why our Pomona service area work starts with a walk around the entry, not a tape measure in the office.
One more thing: on the Phillips Ranch side, we replaced a sun-faded Classic-Craft fiberglass entry on a postwar stucco house where years of Santa Ana wind had pulled the sill and swollen the wood frame. We pulled the slab, reset the frame with new flashing, replaced the rotting sill and weatherstripping with Therma-Tru OEM parts, and re-sealed the stucco junction so the door finally closed flush and stopped drafting. That’s the kind of correction most flatland contractors never think to make.
Therma-Tru Models & Products We Service in Pomona
We work on the full Therma-Tru line: Classic-Craft fiberglass entries, Fiber-Classic slabs, Smooth-Star, and complete door systems with Therma-Tru frames and sill components. When a Classic-Craft or Fiber-Classic slab is structurally sound, we use Therma-Tru OEM hinges, sills, sweeps, and weatherstripping, because aftermarket parts never seat quite the same as factory spec. We carry the common OEM pieces in our local inventory for faster Pomona turnaround and Therma-Tru service in Montclair. Where OEM hardware is backordered, we use quality aftermarket hardware and tell you before we do it.

FAQs – Therma-Tru Construction in Pomona
If the oxidation is superficial and the slab hasn’t delaminated, a professional refinish restores the color and buys you several more years of service. Once the fiberglass starts to chalk deep or hairline cracks form in the finish, replacement is the honest call. Call (877) 752-3951 for a free inspection and an exact recommendation.
Pomona’s summer heat expands the slab and frame, but the more common culprit on older stucco tract homes is a rotted or swollen wood sill at the stucco-to-frame junction. When moisture gets into the sill, the slab binds at the bottom edge. We cut out the rot, reset the frame, and re-flash the junction so it stops sticking for good.
Yes. Rebuilds in the Phillips Ranch and foothill areas carry WUI-era weatherproofing and Title 24 energy standards that often don’t align with older framing tolerances. We check the door plane, flashing, and seal condition against the actual conditions of the house, then correct what’s off before it leaks. Call (877) 752-3951 to schedule a walk-through.
No. Sundance Contractors is an independent door and construction outfit. We install and repair Therma-Tru products and use OEM parts where they matter, but we are not manufacturer-affiliated or authorized by Therma-Tru.
Absolutely. Most homeowners fold the entry door into a kitchen remodel, small bathroom remodel, roof replacement, or full exterior envelope project. One contract, one crew, one schedule, instead of syncing a separate door guy around your other trades. Call (877) 752-3951 for a bundled estimate.
