Therma-Tru Construction in Keller, TX | Sawyer Remodel Fort Worth

Therma-Tru construction service in Keller usually runs $600 to $8,500 depending on whether you need a threshold sealed, a frame rebuilt, or custom glass installed. Our crews have worked on Therma-Tru door systems across Keller since the early 2000s, from fiberglass entry doors on 80s-era slab homes to modern Classic-Craft installations in new luxury builds. What sets our approach apart is that we fix the entire opening, not just the slab, because Keller’s clay soils move doors in ways a handyman patch won’t hold. Call (682) 841-6652 for a written estimate before any work starts.

Why Keller Residents Choose Us for Therma-Tru Service

A dining nook with a built-in banquette

We’re an independent Therma-Tru service provider, not manufacturer-affiliated. That means we recommend what actually holds up in Keller’s climate, not what a corporate catalog says should work. Luca Romano, owner at Sawyer Remodel Fort Worth, learned the trade hands-on at Los Angeles Trade-Technical College and has spent two decades swinging hammers on everything from tract homes to custom builds. He still does walkthroughs himself because he’s seen too many remodels go sideways when the owner stops showing up.

Every job runs under The Relay Visibility Guarantee: a written price before work starts, live arrival time tracking, and before-and-after photo updates. Our technicians are background-checked and uniformed. You’ll know exactly who’s walking into your home before they arrive. And our Therma-Tru sales & service work carries the 365-Day Done Right Promise, so if a frame settles again within a year, we come back and make it right.

Common Therma-Tru Construction Problems We Solve in Keller

  • Frame racking from slab movement. Keller sits on expansive clay that shrinks in summer and swells after rain. When the slab under your entry heaves or settles, the Therma-Tru frame twists with it. The door starts binding at the latch or catching at the top corner. We re-set the frame with composite shims after the slab has been stabilized, or rebuild the opening with a floating jamb system if the movement is seasonal and ongoing.
  • Weatherseal compression and threshold leaks. Homes built in the 1980s and 1990s across Keller often still have their original aluminum or wood thresholds. After a heavy downpour, water finds its way under the sill and into the entry hall. We replace the threshold with an adjustable Therma-Tru unit and seal the exterior with polyurethane joint filler so the next storm doesn’t soak your subfloor.
  • Surface cracking on older Smooth-Star doors. A Smooth-Star fiberglass skin takes a beating under full west sun and hail impact. We see hairline cracks and delamination on doors that face Keller’s afternoon sun without porch cover. If the skin hasn’t separated, we repair and refinish. If the panel is compromised, we’ll tell you honestly that a new prehung unit costs less long-term than repeated patches.
  • Warped jambs from humidity swings. Unconditioned entry halls in Keller get hot and humid in summer, then dry and cold in winter. That cycle twists wood jambs and throws hinge alignment out. We rebuild the jamb, re-hang the door, and adjust the hinges so the reveal stays even through every season.
  • Hinge screw shear from repeated stress. When a slab moves a quarter to half an inch seasonally, the hinge screws take the brunt. We regularly find screws sheared off inside the jamb. The fix isn’t just longer screws, although that helps. It’s re-setting the frame so the door isn’t fighting the foundation every time you open it.

Therma-Tru Service in Keller: What Local Conditions Mean for Your Equipment

A home office with a built-in desk and shelves

Keller sits on a patchwork of Houston Black and Heiden clay, and many 1980s and 1990s neighborhoods like Hidden Lakes and Marshall Ridge were built before post-2000 foundation standards required interior steel reinforcement. What that means for your Therma-Tru door is concrete: frames on original slabs here move 1/4 to 1/2 inch seasonally, enough to shear hinge screws and crack fiberglass corners. A door that latched fine in June might not close by October. The only fix that lasts is re-setting the frame with shims after the slab has been stabilized, or rebuilding the opening with a floating jamb system that lets the frame move independently of the foundation. Few handymen in Keller know to do that. Our crew does it regularly, and our Keller service area coverage means we’re familiar with how specific neighborhoods behave, not just the city in general.

We had a tech called to a home on Bear Creek Parkway in Hidden Lakes where a Classic-Craft six-panel door wouldn’t latch after a dry summer followed by heavy October rains. The slab had dropped 3/8 inch at the strike jamb, leaving a visible gap at the threshold. We pulled the interior trim, shimmed the jamb leg with composite wedges and installed an adjustable Therma-Tru threshold, then sealed the exterior. Six months later the door still closes with one finger and no daylight shows at the sill. The work talks. We just back it up.

Therma-Tru Models & Products We Service in Keller

We work on the full Therma-Tru range that shows up in Keller homes. Classic-Craft Mahogany Collection and Fiber-Classic Oak Collection fiberglass entry doors, Smooth-Star doors from the 1990s and 2000s, and Pulse Series entry doors on newer builds. When parts are still in production, we use genuine Therma-Tru sills, weatherstripping, and adjustable hinges. For obsolete pieces like mid-2000s low-profile thresholds, we source quality aftermarket replacements or fabricate matching profiles in our shop. Our honest repair-vs-replace stance means we rebuild frames and reseal when the slab is intact and the door skin hasn’t delaminated. When the threshold has leaked repeatedly or the panel is compromised, a new prehung unit costs less long-term and we’ll tell you that before you spend money on a patch.
