Therma-Tru Impact Garage Doors: The Lighthouse Point Owner’s Guide

We stock and install Therma-Tru-compatible impact garage doors for Lighthouse Point homes, with typical installed prices running $2,800 to $5,400 depending on door size, wind-load rating, and whether the existing frame needs replacement. Most Therma-Tru impact garage door replacements in Lighthouse Point are completed in a single day once the measured survey is approved. Homeowners usually discover a problem when the door hangs crooked in the frame, the panels delaminate after a storm, or the impact-rated glass unit fogs between the panes - signs that the door’s structural integrity or thermal seal has failed.

Which Therma-Tru Models This Applies To

Therma-Tru’s impact garage door lineup splits into two series relevant to Lighthouse Point: the Classic-Craft and Fiber-Classic collections with impact-rated glass inserts, and the full-view aluminum models with laminated impact glass. The critical compatibility gotcha is the wind-load rating stamped on the interior edge of the door slab or the top rail of the frame. Lighthouse Point sits in Broward County’s High-Velocity Hurricane Zone, which means your replacement must carry a Florida Product Approval with a wind speed rating of 170 mph or higher - not the 140 mph rating common to Orlando and Tampa installations.

To identify your part, check the silver UL or Miami-Dade County label on the hinge edge of the door. The model prefix (CC for Classic-Craft, FC for Fiber-Classic, AL for aluminum full-view) tells us which glazing bead profile and glass retention system you have. These are not interchangeable. We carry OEM Therma-Tru glass packs, glazing beads, and sweep seals on our trucks, plus verified aftermarket equivalents from CWS and PGT where the specification matches exactly. Sonia Raman won’t spec an aftermarket part unless the thickness, laminated interlayer, and DP rating line up to the decimal - Haven Clause 1 means the written spec is the installed product.

Signs Your Therma-Tru Impact Garage Door Is Failing

• Glass fogs between panes. The insulated glass unit’s edge seal has breached, letting moist Atlantic air into the airspace. In Lighthouse Point, we see this accelerate within three blocks of the Intracoastal where salt air degrades the butyl seal faster than inland Broward.
• Door hangs uneven or binds in the frame. The torsion spring system has lost tension, or the hinge screws have backed out of the fiber-reinforced door skin. Therma-Tru’s fiberglass construction won’t rot like wood, but the screw-holding strength depends on the core density at the hinge location.
• Visible delamination or bubbling on the door face. Moisture has penetrated the fiberglass skin and compromised the polyurethane core. This happens most often on south-facing doors in Lighthouse Point where afternoon sun drives thermal cycling.
• Impact glass shows spider cracking but hasn’t shattered. The laminated interlayer is doing its job, but the glass plies have fractured from impact or thermal stress. The door still passes inspection, but the structural redundancy is gone - one more hit and the opening is unprotected.
• Bottom seal leaves a visible gap or daylight. The vinyl or rubber sweep has hardened in the Florida sun, or the aluminum retainer has corroded at the screw points. A 1/4-inch gap at the bottom of an impact garage door defeats the pressure rating for the entire wall assembly.

Replacement Cost & What’s Included

What drives the range: door size, wind-load tier (HVHZ vs. standard), whether we reuse your existing motorized opener, and the condition of the rough opening. Every quote from Sightline Windows & Doors Lighthouse Point is a written line-item scope - Haven Clause 1 - with the measured survey attached. The price on the page is the price on the invoice. Our 365-Day Done Right Promise covers the installation, and the Therma-Tru product warranty runs 10 years on the door slab, lifetime on the glass against seal failure.

DIY or Call Us?

Here’s where we draw the line honestly. A homeowner can safely check the model label, photograph the failure, and verify the gap at the bottom with a flashlight - that’s useful intelligence that speeds our survey. What you should not attempt: replacing the torsion spring system (wound to 100+ foot-pounds of torque, with documented injuries from improper unwinding), removing an impact glass unit from the retention beads (the laminated glass weighs 8-12 pounds per square foot and the pressure-fit beads require specific sequencing), or resetting a door in a wind-load-rated frame (the shim spacing and fastener pattern are engineered; guesswork voids the Florida Product Approval).
