Call (561) 475-3903 to schedule your free estimate.
West Palm Beach presents a rare dual demand for contractors: the downtown luxury tower boom requires current Florida High-Wind code compliance with impact-rated openings, while the protected historic districts of El Cid and Northwood Hills enforce Historic Preservation Board review on exterior alterations. Therma-Tru fiberglass doors navigate both worlds well - the Smooth-Star and Classic-Craft collections offer the detail profiles that historic boards accept, while the Benchmark line meets the impact ratings that new construction inspectors require. We’ve handled both.
The salt air here is not theoretical. It eats hardware, degrades weatherstripping faster than inland Florida markets, and accelerates the UV breakdown that causes fiberglass door skins to craze or delaminate. A contractor who treats West Palm Beach like Orlando will miss these failure modes. We don’t.
Why Trust Rowan Construction Group West Palm Beach for Your Therma-Tru Construction?
Grant Rowan, who leads our West Palm Beach operation, grew up watching his uncle frame houses in Los Angeles’s San Fernando Valley and trained at Los Angeles Trade-Technical College before putting in years on commercial and residential sites across Southern California. For the past several years, he and his crew have applied that same disciplined approach here in West Palm Beach, including projects along Flagler Drive where the combination of historic fabric and hurricane code creates real technical puzzles. He’s known for keeping a clean site, handing over a binder of documentation at project close, and returning calls the same day.
Our technicians are background-checked, uniformed, and trained specifically on Therma-Tru product lines - not just “doors in general.” We know that a Fiber-Classic door with a mahogany grain requires different hinge mortising than a Smooth-Star with its uniform surface, and that the Classic-Craft oak collection’s raised moldings can trap moisture at the bottom rail if the sill pan isn’t detailed correctly. Under Clause 1 of the Haven Standard, the price is written before anyone starts; under Clause 3, no change proceeds without a signed change order. That discipline has kept our projects within a few percent of the agreed cost across 4,000-plus jobs since 2007.
We use OEM Therma-Tru parts for glass inserts and frames, but for weatherstripping, sills, and hardware we source high-quality aftermarket parts that meet or exceed OEM specs. This keeps your repair cost-effective without compromising function. Every visit includes a documented photo record - standard, not an upgrade - so you see what we found and what we did.
Common Therma-Tru Construction Problems We Fix in West Palm Beach
- Fiberglass skin cracking or delaminating from UV and salt exposure. The Smooth-Star’s gelcoat surface holds up well inland, but West Palm Beach’s combination of intense sun and salt-laden air breaks down the resin matrix over 8-12 years. We see this most on south- and west-facing entries in waterfront neighborhoods. Early-stage crazing can sometimes be stabilized; once the glass fibers are exposed, replacement is the honest call.
- Rot and moisture infiltration at the bottom rail. The Fiber-Classic and Classic-Craft collections use composite bottom rails, but if the sill seal fails or the threshold pan was installed without proper slope, water wicks upward. In West Palm Beach’s high water table conditions - often 18-36 inches below grade - capillary moisture compounds the problem. We remove the door, inspect the subfloor, replace the sill with an OEM or upgraded unit, and reseal with marine-grade sealant.
- Warping of door slabs in high humidity. Therma-Tru fiberglass doors resist warping better than steel or wood, but if the frame is out of plumb or the hinge jamb wasn’t shimmed correctly during original installation, the slab can bind or create a gap that leaks conditioned air. We check with a 6-foot level and adjust or rehang rather than assuming the door itself is defective.
- Failed weatherstripping and threshold seals. The Q-Lon or bulb-style seals on Benchmark and Smooth-Star units harden and crack faster in coastal Florida than the manufacturer specs suggest. We stock multiple aftermarket profiles that match the OEM compression specs but use UV-stabilized EPDM or silicone compounds that last longer here.
- Impact code compliance issues on replacements. West Palm Beach sits in the Wind-Borne Debris Region at 130+ mph design wind speed. If your existing Therma-Tru door is not impact-rated and you’re replacing it, the permit triggers additional inspection steps. We pre-stage the documentation - product approval, test report, installation certificate - so the inspection passes the first time.
BeforeAfterTherma-Tru Parts & Our Repair-vs-Replace Approach
We stock OEM Therma-Tru sills, frames, and glass inserts locally for fast turnaround on common repairs. For weatherstripping, thresholds, and hardware, we use aftermarket parts from suppliers like Pemko and Reese that we’ve tested in West Palm Beach conditions and found to outlast the OEM equivalents in salt air.
Our repair-vs-replace decision is straightforward: if the fiberglass skin is cracked through to the substrate, if the frame is rotted, or if the door has been rehung twice and still won’t seal, we tell you. Replacement with a new Therma-Tru unit - typically $4,500-$15,000 installed - is often the better long-term value than throwing parts at a failing door. We were called to a home in West Palm Beach where a Therma-Tru Smooth-Star door had a cracked bottom rail and was leaking water during rain. Our tech removed the door, repaired the frame, installed a new OEM sill and weatherstripping, and adjusted the hinges; the homeowner was relieved to avoid a full door replacement. That honesty is the whole point of how we work.

Our Therma-Tru Service Process - Step by Step
- 1
Diagnosis with documentation. We inspect the door, frame, sill, and hardware, photograph everything, and identify the specific Therma-Tru series and failure mode. You get the photos and a written diagnosis before we proceed.
- 2
Written quote with parts specified. Under Clause 1 of the Haven Standard, you receive a flat price with OEM or aftermarket parts named by brand and model. No “call for a quote” - the number is in writing.
- 3
Repair or install with signed change order. If the scope changes during work - rot discovered behind the frame, for example - work stops until the change order is signed. This is the discipline Haven acquired Rowan for, and it protects both of us.
- 4
Testing and adjustment. We operate the door through multiple cycles, check the seal with a smoke pencil, verify latch engagement, and confirm threshold drainage. On impact-rated units, we verify the label is intact and legible for inspection.
- 5
Warranty documentation and photo record. You leave with a written warranty, the photo record of work performed, and our 365-Day Done Right Promise: if it’s not done right, Rowan makes it right.
Therma-Tru Products We Service & Install in West Palm Beach
We work across the full Therma-Tru residential line: Smooth-Star fiberglass doors for contemporary and coastal modern homes; Classic-Craft oak collection for historic district applications where wood-grain detail matters to preservation boards; Fiber-Classic for the mid-range replacement market; and Benchmark by Therma-Tru for new construction requiring impact ratings and streamlined pricing. We stock sills, weatherstripping kits, and threshold assemblies for all four lines locally, and we can source glass inserts and frame components with 3-5 day lead times for most configurations. Custom sizes and decorative glass options extend that timeline, which we confirm in writing before you commit.
We Also Service These Brands
Our sourcing depth runs across fifty-plus vetted brands - KraftMaid and Wellborn cabinets, Cambria and Silestone countertops, Kohler and Toto fixtures, GAF and Owens Corning roofing, Belgard and Techo-Bloc pavers - so your written quote pulls from competitive supply chains, not a single-source markup. This matters when your Therma-Tru door replacement is part of a larger Kitchen Remodeling, bathroom renovation, or full exterior update.
FAQs - Therma-Tru Construction Service in West Palm Beach
No. We are an independent construction company, not affiliated with or authorized by Therma-Tru. We service Therma-Tru products based on hands-on experience and technical knowledge, and we stand behind our workmanship with our 365-Day Done Right Promise, not a manufacturer’s warranty.
Sometimes, if the cracking is superficial gelcoat crazing without fiber exposure. We sand, fill with compatible resin, and refinish. Once the glass mat is exposed or the crack extends through the skin, replacement is the only durable fix - anything else is a temporary patch that fails within a season in West Palm Beach’s UV and salt environment.
Salt air accelerates hardware corrosion and weatherstripping degradation on all brands; Therma-Tru’s fiberglass construction resists the rust that destroys steel doors and the rot that consumes wood, but the gelcoat surface and bottom rail seals still need attention every 5-7 years in coastal exposure. We see fewer structural failures than with steel or wood, more maintenance needs than the marketing suggests.
We assess honestly. If the frame is square, the sill drains properly, and the hinges are secure, a slab replacement saves money. More often in West Palm Beach’s older homes - especially the 1920s-1940s stock with settled foundations - the frame has racked or the sill has rotted, and full replacement is necessary for a door that seals and operates correctly. We show you the photos and explain which applies.
Yes, with conditions. We require the product approval documentation for West Palm Beach’s wind-borne debris requirements, and we warranty our installation workmanship, not the door itself. If the door arrives damaged or out of spec, we document it and stop work until resolved - our 365-Day Done Right Promise covers what we do, not what you bought.
Standard sizes in Smooth-Star and Benchmark: 1-2 weeks. Classic-Craft with custom glass or stain-grade options: 3-4 weeks. Full custom or oversized units: 6-8 weeks. We confirm lead time in writing with your quote so you can plan accordingly. Call (561) 475-3903 to check current availability for your specific configuration.
Therma-Tru door repair - sill replacement, weatherstripping, hinge adjustment, minor skin repair - typically runs $400-$1,800. Full Therma-Tru door replacement with frame, threshold, and installation: $4,500-$15,000 depending on series, size, glass options, and whether impact rating is required. Here’s how that breaks down:
| Service | Price Range |
|---|---|
| Therma-Tru door repair (sill, weatherstripping, adjustment) | $400-$1,800 |
| Therma-Tru door replacement (standard fiberglass, installed) | $4,500-$15,000 |
These are flat prices with written scope, not estimates that balloon. Call (561) 475-3903 for an exact quote - estimates are free.
Manufacturer warranties typically require authorized service for full coverage. As an independent provider, our work does not extend or transfer Therma-Tru’s factory warranty. However, our 365-Day Done Right Promise covers our workmanship independently - if our repair fails due to our installation, we fix it at no charge. Many homeowners find this more practical than navigating a factory claim, especially for doors past the initial warranty period.
