Trusted Impact Windows for Port St. Lucie Homeowners
Impact window installation in Port St. Lucie typically runs $950 to $1,850 per opening for a standard single-hung or casement window, with full-home retrofits on a 2,000 square foot house usually landing between $22,000 and $38,000 depending on opening count and manufacturer line. Most retrofit installations are completed in one to two days once materials arrive, and TruePane Windows & Doors has served Port St. Lucie homeowners since 2008 through founder Dale Kessler’s craft tradition. The real question is not whether impact windows are worth it here: it is who sets them, how straight they sit in the opening, and whether both warranty layers get registered before the truck leaves your driveway.

What Our Impact Windows Service Includes
Every impact window job we take in Port St. Lucie starts the same way: we measure twice, quote manufacturer lines side by side on paper, and tell you exactly what each layer of glass will and will not do during a storm. Then we install it like we plan to drive past your house for the next thirty years.
Impact Window Installation
Impact windows are not simply thicker glass. They are laminated units built with a polymer interlayer between two panes, designed to take a direct hit from windborne debris without shattering into your living room. In Port St. Lucie, where hurricane-force wind gusts arrive with little warning between June and November, that interlayer is the difference between a cracked pane and a house full of glass. TruePane measures every opening twice, orders each unit to the sixteenth of an inch, and sets it plumb and square. If the pane is not true, the job is not done.
Impact Window Replacement
When an existing impact window fails, it is almost always one of two things: a seal that has let moisture between the panes, or a frame that has shifted out of square from settling. You will see fog between the glass, or the sash will start to bind when you open it in July. We remove the old unit without tearing out your drywall, inspect the rough opening for rot or deflection, and set the replacement to the same line as the original. Both manufacturer warranty layers get registered in writing before we leave, under The Keystone Standard.
Impact Window Repair
Not every compromised impact window needs a full replacement. A torn weatherstrip, a worn balance, or a latch that no longer engages can be repaired at a fraction of replacement cost, and done in a single visit. We carry common OEM parts for PGT, CGI, and other major lines, and when a part is not on the truck, we order it and return when it arrives. You will know the repair price before we start, and the Done Right Promise covers the workmanship.
Impact Window Glass Replacement
A cracked impact pane still needs to be addressed, even if the interlayer held. Once the outer lite is compromised, moisture works its way in, the interlayer begins to cloud, and the unit loses its structural rating. We replace the insulated glass unit to factory specification, matched to the existing frame and tint. The glass order is placed with the original manufacturer whenever possible, so the replacement carries the same design pressure rating as the original install.
Impact Window Hardware and Seal Service
Handles, hinges, rollers, and seals wear out on impact windows just like any other moving part, and in Port St. Lucie’s salt air, they wear a little faster. We service the hardware on every impact window we have ever installed, and most other brands besides. A sticky sash or a window that will not lock is often a fifteen-minute hardware fix, and it is safer and cheaper to address it before the seal fails and the glass fogs. We explain the difference between a hardware repair and a glass replacement before we do either.

Brands We Service for Impact Windows
TruePane is an authorized installer for PGT and CGI, the two dominant impact-rated lines in south Florida, and we have set hundreds of their units in Port St. Lucie over the last years through Dale Kessler’s craft tradition. PGT’s WinGuard series and CGI’s Sentinel line are both Miami-Dade approved, which is the rating you want on the Treasure Coast, and we quote both side by side on paper so you can see exactly what you are buying. We register the manufacturer warranty in writing before the truck leaves your driveway, every time.
We also install and service Therma-Tru lines for homeowners who want impact performance without sacrificing the look of a traditional window. Whether you have PGT, CGI, Therma-Tru, or any other make already in the house, we can help. A square deal means you see every number up front, and you know exactly who will be standing behind the work if something goes wrong.
Signs You Need Impact Windows Right Now
- You still have builder-grade single-pane windows from the 1980s or 1990s. Many Port St. Lucie homes built before the 2001 Florida Building Code went into effect have windows that predate modern impact standards. Those units were designed for a different era of building science, and they will not hold up to a Category 3 storm.
- Your insurance carrier has asked about wind mitigation credits. Impact windows with a Miami-Dade or Florida Product Approval rating can reduce your windstorm premium, and some carriers in St. Lucie County will not write a policy on a home without them. The documentation we provide at install is what your agent needs to apply the credit.
- You hear the glass rattle when a truck drives past on US-1. Loose glass in the frame means the glazing or the gasket has failed, and the unit is no longer performing as a sealed system. It is not just noise: it is air and moisture getting where it should not be.
- Your windows fog between the panes after a hard rain. That is a failed seal, and it will not fix itself. Once the insulating gas escapes, the window loses its energy rating and begins to look permanently dirty from the inside out.
- You plan to stay in this house for another ten or twenty years. If you are not moving, the numbers usually favor impact windows over shutters or panels, because the windows work every day, not just during a storm. They quiet the house, cut your cooling load, and add to the resale value when the day eventually comes.
Our Impact Windows Process - Step by Step
- 1
Measure and quote. A background-checked, uniformed technician comes to your home and measures every opening twice, with a steel tape and a digital level. You get a written quote with manufacturer lines compared side by side on paper, so you can see the differences in glass, frame, and design pressure rating before you spend a dollar.
- 2
Order and schedule. Once you approve the quote, we order the units to the exact size and rating for each opening. We tell you the lead time in writing, and we stay in touch if the manufacturer’s schedule moves. We will be there when we say.
- 3
Painter’s tape and floor protection. Before the first window comes out, we mask the interior trim, lay drop cloths, and clear a path from the door to the openings. We work in your home the way we would work in our own mother’s.
- 4
Set, square, and seal. Each unit goes in plumb and square, shimmed to the rough opening and fastened to the existing structure per the manufacturer’s installation instructions. We flash the exterior, seal the interior, and clean the glass. If the pane is not true, the job is not done.
- 5
Warranty registration and walkthrough. Before the truck leaves your driveway, we register both warranty layers in writing under The Keystone Standard, walk you through each window, and hand you the paperwork. The Done Right Promise covers our workmanship, with no paperwork fights and no arguing.
How Much Does Impact Windows Cost in Port St. Lucie?
What affects the price: the number of openings, the size of each rough opening, the frame material (vinyl is the most common and most affordable; aluminum adds cost but lasts longer in salt air), and the design pressure rating required for your wind zone. The best way to avoid overpaying is to get a written quote with manufacturer lines compared side by side, and to ask exactly what the installation includes before you sign. Our free estimates include a line-by-line breakdown with no surprise charges on the bill. Call (772) 362-3326 to schedule yours. We offer a permanent 5% discount for seniors and veterans, and a free written repair estimate.

What is Impact Windows?
Impact windows are laminated glass units built with a polymer interlayer between two panes, designed to withstand windborne debris during a hurricane without shattering.

They replace traditional windows and work every day, not just during a storm.
How long does impact window installation take?
Most retrofit installations in Port St. Lucie are completed in one to two days once the ordered units arrive on site. A full-home replacement with 15 to 25 openings usually takes two to three working days, depending on access and the condition of the existing frames. We will give you a written schedule before we start and will be there when we say.
How much does impact window replacement cost in Port St. Lucie?
Plan on $950 to $1,850 per standard window opening, and $22,000 to $38,000 for a full-home retrofit on a typical 2,000 square foot house.

Do you service PGT and CGI impact windows?
Yes. TruePane is an authorized installer for PGT and CGI, and we carry common OEM parts for both lines. We also install and service Therma-Tru, and we can work on most other impact-rated brands already installed in Port St. Lucie homes.

A compromised impact window is a safety issue, and we will schedule you as soon as a crew is available. Call (772) 362-3326 any time, and speak to a live person.
What warranty covers impact window installation?
Every job is covered by The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before the truck leaves your driveway. Our workmanship is backed by the Done Right Promise. If it is not done right, we make it right, with no paperwork fights and no arguing.
How should I prepare for impact window installation?
Move furniture and wall hangings at least six feet away from every window opening, take down window treatments, and clear a path from the front door to each room we will work in. We lay drop cloths and mask the trim, but the less you have to move after we arrive, the faster we can get your windows set true and your house sealed up.
