Call (754) 254-8065

Therma-Tru fiberglass doors dominate Boca Raton’s residential market for good reason. They resist the salt air along A1A better than steel, and they hold paint longer than wood in the Florida sun. But they are not maintenance-free. The same humidity that warps wood doors attacks Therma-Tru’s edge grain and bottom rails. The thermal cycling of a south-facing entry in Boca Raton’s heat can stress multipoint lock alignments. And the wind-driven rain of hurricane season finds any gap in weatherstripping.

We are not affiliated with or authorized by Therma-Tru. We are an independent service provider with years of hands-on experience across the full product line. That independence means we recommend what’s actually needed - repair or replacement - without manufacturer incentives steering the call.

Why Trust Rowan Construction Group Boca Raton for Your Therma-Tru Construction?

Our technicians have handled Therma-Tru doors in Boca Raton’s exact conditions - the CBS construction of Arvida-era planned communities, the ARB approval layers of Boca West and Broken Sound, the high-velocity hurricane zone requirements that govern every exterior door replacement in Palm Beach County. We know how a Classic-Craft mahogany-grain door behaves when sprinkler overspray hits the bottom rail six mornings a week. We’ve traced multipoint lock failures on Smooth-Star installations to heat-warped slabs that the original installer never shimmed correctly.

Grant Rowan, our owner, trained in construction technology at Los Angeles Trade-Technical College before spending two decades learning how buildings behave under load, in heat, and through permitting offices. He has led projects across Boca Raton, including tenant build-outs and structural repairs near Mizner Park. His crew runs on documentation-first scheduling: every phase signed off before the next one begins. “Measure twice, document everything, then build” - that’s the standard.

We stock OEM Therma-Tru replacement parts locally - door slabs, frames, glass inserts, multipoint lock cartridges, weatherstripping - because aftermarket parts often fail to match the pre-machined geometry of Therma-Tru’s proprietary systems. When we repair, we repair with parts that fit. When we replace, we specify doors that meet Florida Building Code’s wind-load requirements and, where required by Boca Raton’s Architectural Review Boards, match the aesthetic standards of the community.

Every project carries our 365-Day Done Right Promise, backed by The Haven Standard. Under Clause 1, the price is written before anyone starts. Under our change-order discipline, no work proceeds on a modification until the change order is signed - the administrative practice that has kept our projects within a few percent of the agreed cost across 4,000-plus jobs since 2007.

Common Therma-Tru Construction Problems We Fix in Boca Raton

• Fiberglass skin cracking or delaminating at the bottom rail. This hits Classic-Craft and Fiber-Classic models hardest. The fiberglass skin separates from the polyurethane core where groundwater, sprinkler overspray, or pressure-washing forces moisture past the bottom sweep. In Boca Raton’s planned communities with automated irrigation, we see this routinely on north-facing entries where the sprinkler arc terminates against the door. The damage starts as a hairline crack at the rail joint, then spreads as the core swells. Early intervention - replacing the sweep, resealing the rail, and adjusting sprinkler heads - can save the slab. Left alone, the core degrades and replacement becomes the only option.
• Wood-edge grain swelling and paint failure at the lock rail. Therma-Tru’s wood-edge doors - the oak and mahogany grain options on Classic-Craft - use real wood veneer at the stiles and rails. In Boca Raton’s humidity, this edge grain acts like a wick, drawing moisture into the lock rail where the handle set penetrates. The door swells, sticks in the jamb, and eventually splits the paint film at the lock rail. The fix depends on severity: minor swelling responds to hinge adjustment and resealing; advanced cases require slab replacement with a fully fiberglass-edge Smooth-Star or Pulse model that eliminates the wood component entirely.
• Multipoint lock failure from slab warp. Smooth-Star and Pulse doors use sleek, modern hardware with multipoint locking - bolts at the top, center, and bottom of the jamb. When the slab warps from heat gain (a south-facing door in Boca Raton can reach 140°F surface temperature), the lock points drift out of alignment. The handle gets stiff, then jams, then fails to latch at all. Generic contractors often replace the entire lock set when the real problem is slab geometry. We measure the warp, shim or plane as needed, and realign the multipoint mechanism - saving the hardware and the door.
• Weatherstripping and sweep compression. Therma-Tru’s factory weatherstripping is compression-molded vinyl with a felt facing. In South Florida’s UV and ozone, it becomes brittle within three to five years, losing its spring-back. The door bottom sweep, a dual-fin design on most models, compresses flat and allows wind-driven rain to pass the threshold. During Boca Raton’s summer storms, this means water intrusion, stained interior flooring, and eventually subfloor damage. We replace with OEM Therma-Tru weatherstripping kits - the geometry is proprietary, and universal strips never seal correctly - and we inspect the threshold pan for corrosion while we’re at it.
• Glass insert seal failure in decorative lite models. Classic-Craft and some Fiber-Classic configurations use simulated divided-lite or full-view glass inserts with factory-applied SDL (simulated divided lite) grids. The dual-pane insulating glass unit (IGU) seals can fail in the thermal stress of Boca Raton’s climate, fogging between panes or depositing mineral residue. We source replacement IGUs through Therma-Tru’s distribution network, matching the grid pattern and exterior profile exactly. For impact-rated doors, the replacement IGU must carry the same Miami-Dade or Florida Product Approval number as the original - a detail we verify before ordering.

Therma-Tru Parts & Our Repair-vs-Replace Approach

We use OEM Therma-Tru replacement parts whenever available. The multipoint lock cartridges, hinge sets, and weatherstripping profiles are proprietary - aftermarket equivalents often misalign by fractions of an inch that become gaps in the seal or binding in the latch. For glass inserts, the SDL grid spacing and exterior profile must match exactly, or the door fails ARB inspection in gated communities like Woodfield or Boca Pointe.

Our repair-vs-replace decision is straightforward. Minor seal or hardware issues get targeted repair with OEM parts. Structural delamination, core saturation, or slab warp beyond adjustment means replacement - and we tell you that before we quote, not after we’ve tried three repairs that didn’t hold. We recently repaired a Therma-Tru Classic-Craft entry door in a Boca Raton home where the bottom rail had cracked and the door was sticking badly. After confirming the slab was still structurally sound, we replaced the failed bottom sweep and weatherstripping with OEM Therma-Tru parts, adjusted the hinges, and re-finished the affected area. The door now closes smoothly and seals tightly against driving rain.

For replacement, we specify Therma-Tru doors with Florida Product Approval for high-velocity hurricane zones, impact-rated glass where required, and finishes that satisfy Boca Raton’s ARB standards. Call (754) 254-8065 to schedule an assessment - estimates are free, and the price is written before any work starts.

Our Therma-Tru Service Process - Step by Step

1. 1
   Diagnosis with documentation. We inspect the door system - slab, frame, hardware, weatherstripping, threshold, and surrounding trim - and photograph every condition we find. For multipoint lock issues, we measure slab warp with a straightedge and feeler gauge. For moisture damage, we probe the bottom rail with a moisture meter. You receive the photo record before we quote.
2. 2
   Written quote with scope. Under Clause 1 of The Haven Standard, the price is flat, written, and includes all parts and labor. If we recommend replacement, the quote specifies the Therma-Tru model, glass option, finish, and hardware grade. No work proceeds until you approve in writing.
3. 3
   Repair or install with OEM parts. For repairs, we use Therma-Tru factory parts from our local inventory or next-day distribution. For installations, we rough-frame to Therma-Tru’s spec, shim the slab plumb and square, and seal with code-approved flashing tape and sealant.
4. 4
   Testing and sign-off. We cycle the door fifty times, check multipoint lock engagement at all three points, spray-test the weatherstripping with a calibrated nozzle, and verify threshold drainage. Every phase signed off before we leave.
5. 5
   Warranty and record. The 365-Day Done Right Promise covers our workmanship. The documented photo record, signed change order (if any), and written warranty are your permanent project file.

FAQs - Therma-Tru Construction Service in Boca Raton

Is Rowan Construction Group Boca Raton authorized by Therma-Tru?

No. We are an independent Therma-Tru service provider, not affiliated with or authorized by the manufacturer. Our expertise comes from years of hands-on installation and repair across the full Therma-Tru line, not from a dealer agreement. This independence lets us recommend repair over replacement when that’s the honest call, and source OEM parts without channel restrictions.

Can you replace just the glass in my Therma-Tru door, or do I need a whole new door?

In most cases, yes - the glass insert can be replaced independently of the slab. Therma-Tru uses removable glass inserts held by interior stop molding or exterior snap-in bezels, depending on the model and vintage. We source replacement IGUs with matching SDL grid patterns and, for impact-rated doors, the same Florida Product Approval number. Replacement makes sense when the slab and frame are sound; if the frame is rotted or the slab delaminated, a full door system is the better investment. Call (754) 254-8065 and we’ll assess which path fits your door.

Why is my Therma-Tru door swelling and sticking during Boca Raton’s rainy season?

Swelling and sticking on Therma-Tru doors almost always traces to moisture intrusion at the wood-edge stiles (Classic-Craft oak or mahogany grain) or bottom rail. The edge grain wicks water from humidity, sprinkler spray, or wind-driven rain past a failed sweep. The door expands, binds in the jamb, and eventually splits the paint film. The fix ranges from hinge adjustment and resealing (early stage) to slab replacement with a Smooth-Star or Pulse model that eliminates wood edges entirely. We diagnose with a moisture meter and photograph the damage so you see what we see. Call (754) 254-8065 for a free assessment.

My Therma-Tru multipoint lock is jammed - can it be repaired or does it need a new door?

Multipoint lock jams on Smooth-Star and Pulse doors are usually alignment issues, not hardware failure. Heat warp in the slab shifts the lock points relative to the strikes. We measure the warp, shim or adjust the slab, and realign the mechanism - often saving the entire lock set. Only if the lock cartridge itself has failed (broken internal springs, worn cams) do we replace the hardware. We stock common Therma-Tru multipoint cartridges for same-day repair when that’s the issue. Call (754) 254-8065 and we’ll determine which scenario applies.

Do you install Therma-Tru doors that meet Florida’s impact and wind-load requirements?

Yes. Every Therma-Tru door we install in Boca Raton carries Florida Product Approval for high-velocity hurricane zones, with impact-rated glass where the opening requires it. We engineer the rough opening to Florida Building Code standards, install code-approved flashing and sealant, and document the installation for permit inspection. In ARB-gated communities, we also verify that the selected style, finish, and glass configuration match community standards before ordering - avoiding the permit delays that derail projects in Boca Raton’s dual-track approval system.

What’s the average lifespan of a Therma-Tru fiberglass door in South Florida?

With proper maintenance - annual weatherstripping inspection, bottom sweep replacement every three to five years, and prompt repair of any skin cracks - a Therma-Tru fiberglass door lasts twenty to thirty years in Boca Raton’s climate. The fiberglass skin itself is stable indefinitely; the failure points are the wood edges (on Classic-Craft), the seal systems, and the hardware. Neglect the sweep, and bottom rail delamination can destroy a ten-year-old door. Maintain it, and the same door outlasts two wood replacements.
