AfterTherma-Tru Impact Windows in Deerfield Beach: What to Know First
Therma-Tru impact windows in Deerfield Beach typically cost between $900 and $2,600 per opening installed, depending on frame series, size, and whether the existing rough opening needs correction. Most single-opening replacements take one day once the glass arrives, and full-home jobs run three to five days. TruePane Windows & Doors is an independent Therma-Tru service provider, not a factory-authorized dealer, which means we quote the work honestly and register every warranty layer in writing before we leave the driveway. Call (786) 743-5882 for a free estimate.
This page is for homeowners who already have Therma-Tru doors or windows and want impact-rated replacements that actually fit, seal, and hold up against South Florida weather. If you have been told a Therma-Tru frame “cannot take impact glass” or that you need to replace a whole door when only the glass unit failed, this page will set the record straight.
How Therma-Tru Products Fail - and How We Fix Them
- Smooth-Star fiberglass doors with failing glass inserts. The Smooth-Star line is common in Deerfield Beach homes built in the 1990s and early 2000s. The original double-pane inserts fog when the internal seal degrades, and the white fiberglass skins will chalk and pit from salt air faster than painted steel. We can often remove the failed insert and set a code-rated impact unit into the existing slab, saving the door itself. If the fiberglass has delaminated around the opening, we will tell you plainly and quote a full slab replacement instead of caulking over rot.
- Classic-Craft and Fiber-Classic door slabs that sag and bind. Therma-Tru’s higher-end lines use a polyurethane core with composite stiles. Heavy impact glass adds weight, and on a door that has been hung for fifteen years, the hinge mortises may be wallowed out and the slab will drag on the sill. The failure is rarely the door; it is the installation. We correct the hinge geometry, reset the slab, and square the frame before the impact unit goes in.
- Dented or corroded aluminum storm-door frames around older Therma-Tru entry doors. This is a Deerfield Beach pattern we see constantly, especially east of Federal Highway. Salt air works on exposed aluminum corners until the frame twists. A twisted frame will not seat an impact insert properly, which means air leaks and eventually water. We replace or straighten the frame before setting glass, and we use stainless fasteners on every exterior mount.
- Benchmark door frames with failed sill pans. The Benchmark series is Therma-Tru’s builder-line door system. In production-built homes, the original sill pan may be thin plastic that cracks under years of sun exposure and foot traffic. When we pull an old Benchmark door to convert it to impact, we replace the pan with a properly sloped and flashed aluminum or composite pan. Skipping that step is the difference between a door that drains and a door that rots the subfloor.
- OEM insert glass that does not match current wind-load maps. Therma-Tru’s factory inserts are rated, but older units may not meet the current Miami-Dade County test protocols for the wind zone your section of Deerfield Beach now sits in. We verify the pressure rating against the address, not the assumption. When a factory insert is not stamped for your zone, we source a code-compliant impact insert from a rated fabricator and document it so the permit closes clean.
Our Therma-Tru Impact Windows Process
- 1
Measure, measure again, then measure the rough opening. Dale Kessler keeps a folding rule in the truck for a reason. We measure the existing frame, the opening, and the reveal on all four sides before anything is ordered. If the rough opening is out of square by more than a quarter inch, that gets corrected before glass arrives.
- 2
Identify the exact Therma-Tru series and the failure point. We document the slab material, hinge style, sill condition, and glass type. This determines whether the job is a glass insert replacement, a frame repair, or a full unit replacement.
- 3
Present the options on paper, side by side. You see the OEM insert price, the quality aftermarket impact insert price, and any frame work required, written out in plain language. No verbal estimates, no fuzzy allowances. As Dale says, “If it is not in the contract, it is not in the scope.”
- 4
Install with the frame corrected first. TruePane techs do not set impact glass into frames that are not square, level, and sealed. The frame work comes first, and it is included in the quote, not discovered later as a change order.
- 5
Test the seal and the operation before we call it done. We check the reveal, cycle the hardware, and run water on the sill. The founding rule applies: if the pane is not true, the job is not done.
- 6
Register both warranty layers before leaving. The Keystone Standard means the manufacturer warranty and the TruePane workmanship warranty are both registered in writing, with durations stated, before the truck leaves your driveway.
What Therma-Tru Impact Windows Costs in Deerfield Beach
Here is what we typically see for Therma-Tru related impact work in Deerfield Beach:
- Impact glass insert into an existing Therma-Tru door slab: $900 to $1,500, depending on glass size and wind-zone rating.
- Full smooth fiberglass impact door replacement (Smooth-Star or Benchmark): $1,800 to $3,200 installed.
- High-end Classic-Craft or Fiber-Classic full replacement: $2,800 to $4,600 installed, more for custom sizes or sidelite configurations.
- Frame correction or sill pan replacement on an existing opening: $250 to $700, depending on the extent of the rot or twist.
- Full-home Therma-Tru impact conversion (8 to 12 openings): $14,000 to $32,000, with per-opening pricing that drops as the job scales.
What moves the price: whether the existing frame can stay, whether the rough opening is square, the wind-zone requirement for your street address, and whether you choose OEM inserts or rated aftermarket units. We quote both, on paper, so you choose with full information. Call (786) 743-5882 for a free estimate.

FAQs
In most cases, yes. We can set a code-rated impact insert into a Therma-Tru door slab if the slab is sound, the frame is square, and the hinges are solid. The original door does not need to be thrown away just because the glass unit failed. Call (786) 743-5882 and we will inspect the door and tell you what your slab can actually carry.
If you are past the original warranty period, a quality impact insert from a rated fabricator will not affect any remaining coverage on the door slab itself. We document every job and register both warranty layers in writing, so nothing is left to memory. If the door is still under factory warranty, we will tell you before we touch it what the safest path is.
Most single-opening replacements are done in one day once the glass arrives. Lead time on impact-rated glass is typically three to five weeks in South Florida, so the smartest move in Deerfield Beach is to get measured before hurricane season tightens the supply chain. On the day of install, our crew arrives on time, in uniform, and leaves the opening clean.
Replacing only the glass insert is almost always less expensive than a full door, often by $1,000 or more. But if the frame is twisted or the sill pan has failed, putting new glass into a bad frame is wasted money. We will show you both numbers on paper and let you decide from there, no pressure.
Yes. Impact-rated window and door work in Deerfield Beach requires a permit and a wind-load calculation matched to your address. We handle the permit, the inspection, and the documentation. The job is not done until the inspector signs off and the paperwork is in your hand.
