Trusted Window Replacement for Port St. Lucie Homeowners
Window replacement in Port St. Lucie runs about $550 to $1,400 per opening for a standard double-hung insert, and $900 to $2,500 or more for a full-frame replacement, depending on size, glass package, and whether the opening has hidden rot or water damage. Most single-opening replacements we handle are finished in one visit. TruePane Windows & Doors has been doing this work here since Dale Kessler started the company in 2008, and the trade runs deeper than that in our family. Call (772) 362-3326 and a live person answers, any hour, any day.
If you have lived in your Port St. Lucie house for twenty years or more, you already know which windows fog, which ones stick in July, and which frame you can feel the afternoon heat radiating through. You are not shopping for the cheapest bid. You want it done right the first time by a company that will still answer the phone in thirty years. That is who we are. Our work is covered by the Done Right Promise, and both manufacturer warranty layers get registered in writing before the truck leaves your driveway.
What Our Window Replacement Service Includes
Full Frame Replacement
A full frame replacement means the entire window comes out: sashes, frame, casing, and all. We expose the rough opening down to the studs, inspect for rot and termite damage, repair or replace what needs it, flash and seal the opening properly, and set a new window that is square and true. Here in Port St. Lucie, we regularly find hidden water damage around windows that faced years of summer storms without proper flashing. This is the right choice when your existing frames are soft, leaking, or so far out of square that an insert would simply carry the old problems forward. TruePane treats a Full Frame Replacement as a craft commitment, not a parts swap. We measure every opening twice, order the exact unit, and do not set a window that cannot close on a dollar bill held at the jamb.

Insert Window Replacement
An Insert Window Replacement, sometimes called a pocket or retrofit window, leaves your existing frame in place and fits a new window unit inside it. It costs less than a full frame replacement, creates less disruption to interior trim and exterior siding, and works well when the existing frame is sound, square, and dry. In Port St. Lucie homes built in the 1980s and 1990s, we install a lot of inserts where the original aluminum frames are still solid but the glass seals have failed and the single-pane heat gain is punishing. We check the existing frame carefully before recommending an insert, because a rotted or out-of-square frame will ruin a good window in a few years. If the frame is not true, we tell you straight, and we show you the numbers for both options on paper.

Storm Window Replacement
Storm windows are the outer layer of glass in an older double-window setup, the workhorse that takes the wind-driven rain and the flying debris from summer squalls, and the acrylic or glass panel that often gets cracked, hazed, or broken first. When a storm window fails, you lose its protective layer and the inner window suddenly has to do a job it was never designed to do alone. We replace broken, clouded, and warped storm windows with units sized to your existing tracks, and we can upgrade the glass to impact-rated or low-E while we are at it. The replacement has to seat flush or it rattles in the wind and lets water in. We measure, set, and test every storm window the same way we set a primary window: if the pane is not true, the job is not done.

Energy-Efficient Upgrade
An Energy-Efficient Upgrade means replacing old single-pane or failed-glass windows with units built for Florida heat: low-E coatings, argon or krypton gas fill, warm-edge spacers, and tight weatherstripping. Port St. Lucie homeowners see the biggest difference in rooms with west or south exposure, and in the summer, when a low-E window can cut solar heat gain dramatically compared to builder-grade glass. We quote manufacturer lines side by side on paper so you see exactly what each glass package costs and what it saves in cooling load. The 5% senior and veteran discount applies to every job, and the maintenance check is a good way to check the condition of windows you are not yet ready to replace. We register both warranty layers in writing, durations stated, before the truck leaves the driveway.

Historic Window Restoration
Some Port St. Lucie homes, particularly in older neighborhoods and along the river, have original wood windows with real soul, and the right answer is not always a new vinyl unit. Historic Window Restoration means we rebuild what you have: strip failing glazing, repair or splice rotted wood, replace broken weights or balances, reglaze the panes, and weatherstrip for function without erasing character. We do this work because Dale Kessler learned it as a second-generation glazier, and because a fifty-year-old true wood window, properly restored, can outlast a cheap modern replacement. The work takes more hours than an insert, and we charge for those hours honestly, with upfront pricing and no surprise line items. If a window is beyond saving, we say so and show you replacement options that respect the home’s era.

Brands We Service for Window Replacement
We are an authorized installer for more than a dozen manufacturer lines, including, PGT, and CGI. When you call us about an Andersen or Pella replacement in Port St. Lucie, you are talking to a crew that has set hundreds of those units and knows how each line seats, flashes, and latches. We carry the right shims, the right flashing tape, and the right fasteners for the brands we install, and we register every manufacturer warranty in writing.
For impact-rated work on the Treasure Coast, we lean on PGT and CGI, two Florida manufacturers that know hurricane cycles and coastal salt air. For coastal modern builds and custom openings, we specify ES Windows and ECO Window Systems where the architecture calls for it. We also service and replace CWS units when a homeowner needs a match for an existing line. Whether you have one of those brands or any other make, we can help. The brand does not change the standard. If the pane is not true, the job is not done.
Signs You Need Window Replacement Right Now
- You feel heat radiating through the glass from three feet away. Single-pane and failed double-pane windows let Port St. Lucie afternoon sun hit your skin like a heat lamp. That is not an insulation problem; it is a failed window doing nothing to block solar gain. The right glass package stops the heat before it enters the room.
- Condensation sits between the panes, not on the surface you can wipe. Interior fog you can wipe is humidity. Fog you cannot reach means the seal has failed and the inert gas fill is gone. That window is no longer insulating, and it will only get cloudier.
- A window sticks, binds, or will not stay up without a prop. Warped frames, failed balances, and swollen wood are all signs the window is no longer functioning. Port St. Lucie humidity tends to make wood frames swell in summer and shrink in winter, and when they stay swelled, the window has a structural problem, not a seasonal one.
- You can hear your neighbor’s pool pump or the traffic on US-1 like the window is open. Modern laminated and double-pane glass cuts noise meaningfully. If your window lets in as much sound as light, the seal or the sash is compromised. Replacement with the right glass package is the durable fix.
- Water stains appear on the wall or sill below a window after a hard rain. The window is leaking. Caulk and paint will not fix a failed flashing job or a rotted sill. Port St. Lucie gets real wind-driven rain; water that gets into the wall is already doing damage you cannot see.
Our Window Replacement Process - Step by Step
- 1
You call, we listen. A live person answers at (772) 362-3326, 24 hours a day, seven days a week. No voicemail tree, no callback form, no regional call center. We ask about the window, the symptoms, the age of the home, and what you have already tried. Then we schedule a time that works, and we are there when we say.
- 2
We measure and inspect. A background-checked, uniformed technician comes to your home, measures every opening twice, and inspects the frame, the rough opening, the flashing, and the siding around the window. We look for the rot, the out-of-square jamb, the termite trail, the water stain that tells us what is really going on behind the wall. If we find a problem, we show it to you and explain what it means before we quote a dollar amount.
- 3
You get a written, line-item quote. We quote manufacturer lines side by side on paper so you see exactly what you are buying and what each option costs. The price we quote is the price you pay. No change orders, no surprise line items, no second appointment left hanging. A square deal, in writing.
- 4
We do the work right the first time. Our installers show up in uniform, prepared, and on time. We pull the old unit, repair the opening if needed, flash and seal it properly, set the new window true, and dress it inside and out. We clean up before we leave. The founding rule governs every install: if the pane is not true, the job is not done.
- 5
We register your warranties and stand behind the work. Before the truck leaves the driveway, we register both manufacturer warranty layers in writing, with durations stated, and hand you copies. Then the Done Right Promise begins, our guarantee on workmanship. If it is not done right, we make it right. No paperwork, no arguing, no fine print that covers neither.
How Much Does Window Replacement Cost in Port St. Lucie?
A typical insert window replacement in Port St. Lucie runs $550 to $1,400 per opening for a standard double-hung unit with a mid-grade glass package. A typical full frame replacement runs $900 to $2,500 per opening, depending on the condition of the rough opening and whether the opening needs structural repair. Impact-rated windows for coastal exposure and larger custom openings run higher, often $1,500 to $4,000 per opening or more. Here are the ranges we see most often:
| Replacement Type | Typical Range Per Opening | Notes |
|---|---|---|
| Insert / pocket replacement | $550-$1,400 | Assumes sound, square existing frame |
| Full frame replacement | $900-$2,500 | Includes opening repair where needed |
| Storm window replacement | $300-$800 | Standard to impact-rated glass |
| Energy-efficient upgrade | $700-$1,800 | Low-E, gas fill, warm-edge spacers |
| Historic restoration | $400-$1,200 | Per window, labor-intensive work |
| Impact-rated window | $1,500-$4,000+ | Coastal code, laminated glass |
What moves the price is not the brand name printed on the glass. It is the condition of the opening, the size of the unit, the glass package, and whether the rough opening needs repair before any window can be set correctly. A cheap bid on a rotted opening is not a deal; it is a deferred bill. The way to avoid overpaying is to ask for a line-item quote that separates the cost of the window from the cost of the labor and the opening repair, and to ask whether both warranty layers get registered in writing. Our free estimates include all of that. Call (772) 362-3326 and we will come measure, inspect, and put the numbers on paper.

Frequently Asked Questions - Window Replacement in Port St. Lucie
Window replacement is the process of removing an existing window, or the failed glass inside it, and installing a new unit in the same opening. The two main approaches are insert replacement, which keeps the existing frame, and full frame replacement, which removes everything down to the studs. The right choice depends on the condition of the frame, the age of the house, and whether hidden water damage is present. Call (772) 362-3326 and we will tell you which approach fits your opening after a proper inspection.
Most single-opening replacements in Port St. Lucie are finished in one day, including cleanup. Full frame replacement with opening repair can take a day and a half to two days, depending on what we find behind the wall. Whole-house jobs, ten or more windows, usually take three to five working days. We schedule the work in writing and we are there when we say.
