Trusted Window Installation for Port St. Lucie Homeowners
Window installation in Port St. Lucie is not a one-size-fits-all trade. The salt air, the afternoon storms that roll in off the Atlantic, the way an east-facing bedroom bakes from June through September, these all decide how a window should be set and sealed. Most window installations here run from $450 to $1,200 per opening depending on the unit and the framing, and the work typically takes one day for a standard retrofit. TruePane Windows & Doors has been doing this in your community since 2008. We answer the phone at (772) 362-3326, and we send a background-checked, uniformed technician to measure every opening twice before a single pane is ordered.
Dale Kessler founded TruePane in 2008 on a rule he learned from his father, a glazier who believed a window was only finished when it sat true in the frame. That rule has not changed. If the pane is not true, the job is not done. The work carries the Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before our truck leaves your driveway.
What Our Window Installation Service Includes
Window installation covers every step from removing the old unit to setting, leveling, sealing, trimming, and registering the warranty on the new one. TruePane does not subcontract the install to another crew. The technician who measures your openings is a TruePane employee, and the crew that sets your windows is the same crew that will come back if anything needs attention during the Done Right Promise window. A live person answers the phone 24 hours a day, 7 days a week, backed by a company that sponsors county fairs and church roof funds because it plans to be here in thirty years.
Casement Windows
Casement Windows hinge on one side and crank outward, which makes them the best choice for catching the cross-breeze that comes off the St. Lucie River in the evening. You want casements when you need maximum ventilation and a tight seal against wind-driven rain. We set each casement with a continuous seal and check the crank operation at full open and full closed before we call the job done. On coastal lots in Port St. Lucie, we recommend units with stainless hardware so the salt air does not bind the operator in three years.

Awning Windows
Awning Windows hinge at the top and open outward from the bottom, so you can leave them cracked open during a light rain without water coming in. They work well in bathrooms, over kitchen sinks, and anywhere you want ventilation without sacrificing privacy. TruePane installs them with proper flashing so the sill sheds water the first time and every time after. We also confirm the operator arms are rated for the size of the sash, because an undersized arm is the most common reason an awning window starts to sag.

Fixed & Picture Windows
Fixed & Picture Windows do not open, which means the entire job is in the glazing and the seal. You choose these for the view, whether that is a preserve lot, a canal, or a clean line of palms. We set them level and square, then apply an exterior seal detail that handles Port St. Lucie’s humidity without trapping moisture inside the frame. And we register both warranty layers on glass and frame before we leave, in writing, so you never have to argue about coverage later.

Single & Double Hung
Single hung windows have a fixed top sash and a bottom sash that lifts. Double hung windows let both sashes move, which gives you better airflow and easier cleaning from inside the house. In Florida homes, these are the most common retrofit replacements, and the biggest installation mistakes are sloppy leveling and weak sash balances. TruePane measures the opening at three points on every side, sets the frame dead plumb, and sizes the balances to the actual sash weight so the window stays where you put it.

Sliding Windows
Sliding windows move horizontally along a track, and they are a natural fit for wide openings, breezeways, and rooms where you do not want a sash swinging into the space. The track is everything on these. We install sliders with the track dead level and the rollers adjusted at both ends, because a slider that binds in July is a slider that was never set right in January. We also check the weep holes are clear so water drains out instead of pooling in the track after a storm.

Bay & Bow Windows
Bay & Bow Windows project outward from the wall, which changes the roofline, the framing, and the load path. These are not a simple swap, and the install must be approached as structural work, not just glazing. TruePane builds the projection to support the glass and the seat board, ties the new framing into the existing wall, and flashes the top and bottom so a hard rain never finds its way in. We also review the roof detail above the projection, because that is where bay windows leak first if the flashing is short.

Garden & Basement Windows
Garden windows sit like a small glass box off the wall, usually over a kitchen sink, and they give you a ledge for plants or a few inches of extra counter space. They need exceptional sealing at the top seam because the weight of the glass wants to pull the unit away from the house. We install garden windows with reinforced support brackets and a perimeter seal that holds in high humidity. Basement windows are less common in Port St. Lucie, but where they exist, we treat them the same way: sized to the opening, set square, and sealed against ground moisture.

Brands We Service for Window Installation
TruePane is an authorized installer for more than a dozen manufacturer lines, including, PGT, CGI, and ES Windows. When we quote a job, we put the manufacturer lines side by side on paper so you see exactly what you are buying, not just a price with no context. That matters because two windows can look identical on a showroom floor and perform very differently in a house off Becker Road that takes the full afternoon sun.
We work with ES Windows and their heavier aluminum profiles when a homeowner wants a modern, narrow sightline that still meets coastal wind codes. We have installed countless ECO Window Systems units in newer neighborhoods around Tradition and Torino, and we know their frame details well enough to quote them accurately without a second trip. For homeowners who want a strong value on a straightforward replacement, ViewLux gives us a dependable insulated unit we can stand behind with the same Done Right Promise. Whether you have one of these brands or any other make, we can help. A live person answers the phone at (772) 362-3326, and honest guidance costs you nothing.
Signs You Need Window Installation Right Now
- Fog between the panes. A seal has failed and the insulating gas is gone. The window still looks fine from across the room, but it is no longer doing the job you paid for. In Port St. Lucie humidity, that fog turns to condensation that drips into the frame and starts rot you cannot see.
- You can feel air moving around the frame. Hold a damp hand near the window edge on a windy day. If you feel air, the seal is broken or the frame has shifted. That is conditioned air leaving your house every hour the system runs.
- The sash binds or will not stay up. A window that fights you when you open it has a balance problem, a track problem, or a frame that is out of square. Each is fixable, but left alone it gets worse and starts wearing the hardware and the weatherstripping.
- Water stains on the interior wall or sill. Stains under a window mean water is finding a path in. It may be the flashing, the seal, or a crack in the frame, but the source needs to be found now, not after the drywall swells and the mold starts. In one Port St. Lucie home near Sandpiper Bay, a small sill stain turned out to be a failed flashing detail that had been soaking the wall cavity for two wet seasons.
- Condensation on the interior glass when the AC runs. This is different from fog. Interior condensation means the glass temperature is dropping below the dew point, and the window is transferring too much heat. That is an efficiency signal, and it is costing you money on every cooling bill.
Our Window Installation Process - Step by Step
1. You call and talk to a person.
No voicemail tree, no callback form, no regional call center. You call (772) 362-3326 and a live person answers, 24 hours a day, 7 days a week. We ask a few questions about the house, the windows, and what you are seeing, then we schedule a time that works for you.
2. We measure every opening twice.
A uniformed, background-checked technician comes to your home and measures each window opening at three points on every side: top, middle, bottom, left, right, corner to corner. We also check the existing frame for square, level, and plumb, because that tells us whether this is a clean retrofit or a job that needs framing corrections. We do not measure from the old window; we measure the structural opening.
3. You get a written, line-item quote.
We put the manufacturer lines side by side on paper so you can see what each option costs and what each includes. The quote shows the unit, the glass package, the frame material, the labor, and the warranty details. No surprise line items on the bill later, because we do not write estimates we cannot honor.
4. We install on schedule and clean as we go.
On install day, the crew arrives in uniform, protects the floors, and removes the old window without tearing up your trim. We set each unit level and square, add new insulation where the old has settled, flash the exterior, and seal the interior. We haul the old windows away and leave the work area cleaner than we found it. Most jobs are completed in a single visit.
5. We register both warranty layers before we leave.
This is The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before the truck leaves the driveway. You get a copy of the registration. If anything comes up during the Done Right Promise window, you call us and we make it right, no paperwork fights and no arguing. We answer the phone when you call.
How Much Does Window Installation Cost in Port St. Lucie?
Window installation in Port St. Lucie typically runs from $450 to $1,200 per opening for a standard retrofit unit installed into an existing frame. A full-frame replacement that requires opening the wall and replacing the trim might run $900 to $2,000 per window. Casements and awnings trend toward the higher end because they have more hardware and operate under seal pressure. Bay and bow windows are their own category, and in Port St. Lucie those jobs usually start around $6,000 and go up based on the projection, the glass package, and the roof detail.
What moves the price is straightforward: the size of the unit, the frame material, the glass package, whether the existing frame is square or needs correction, and whether we are doing a retrofit or a full-frame replacement. Impact-rated glass costs more than standard insulated glass, and for good reason, it is built to a different standard. You avoid overpaying by getting a written quote that separates the unit cost from the labor cost and shows what each manufacturer line costs side by side. That is how we quote every job. A free estimate includes measurements, a written scope of work, and a line-item price. No obligation, and the price we quote is the price we honor. Call (772) 362-3326 to schedule yours.

Frequently Asked Questions - Window Installation in Port St. Lucie
Window installation is the process of setting a new window unit into a prepared opening, including the work needed to level, plumb, seal, flash, and trim the opening so the window performs properly and keeps water out. TruePane does both retrofit installation, where the new unit is set into the existing frame, and full-frame replacement, where the old frame is removed and a new one is built and flashed. Every job is measured twice, quoted in writing, and covered by the Done Right Promise.
A standard retrofit installation for one to four windows takes a single day. A full-frame replacement or a larger job of eight to twelve windows may take two to three days, and a bay or bow window install can add a day for the framing and roof detail. Most jobs in Port St. Lucie are completed in a single visit, and we tell you the schedule before the work starts so there are no surprises.
