Trusted Window Installation for Stuart Homeowners
Window installation in Stuart, FL typically costs $450-$1,350 per window for most standard replacements, with full-home projects ranging from $6,000 to $24,000 depending on window count, frame material, and whether impact-rated glass is required. Most installations take one day per 8-10 windows once materials arrive, and TruePane Windows & Doors has been setting windows square in Martin County homes since 2008 through our craft tradition. If you’re tired of drafts, sticking sashes, or windows that fog between the panes, call (754) 324-4646 and a live person will answer, day or night. Dale Kessler founded this company in 2008 on a simple rule that still governs every install: if the pane is not true, the job is not done.

Stuart homeowners deal with salt air, hurricane seasons, and afternoon thunderstorms that punish poorly set windows. We’ve replaced windows in Sewall’s Point homes where original 1970s aluminum frames had corroded at the corners, and in Rocky Point condos where out-of-square rough openings made factory windows bind within two summers. The fix is not a thicker bead of caulk. It’s a measured opening, a properly shimmed frame, and a crew that treats a 1/16-inch deviation as a reason to stop and re-do the work. That’s the standard we hold ourselves to, and it’s why most of our Stuart work comes from neighbors who watched a TruePane crew on their street and asked for our number.
Key Takeaways:
- Window installation in Stuart averages $450-$1,350 per window, with impact-rated glass running higher.
- TruePane has served Martin County since 2008 through a second-generation glazier’s craft tradition.
- Every install is backed by our Done Right Promise and The Keystone Standard.
- Background-checked, uniformed technicians measure every opening twice before ordering.
- Call (754) 324-4646 anytime - a live person answers 24/7, not a voicemail tree.
What Our Window Installation Service Includes
We install every window type you’ll find in Stuart homes, from 1950s jalousie replacements in Port Salerno to modern impact-rated casements in new construction. Here’s what each style involves and how we handle it specifically.
Casement Windows
Casement windows hinge at the side and crank outward, catching the prevailing breeze when Stuart’s coastal air finally moves. They’re the tightest-sealing operable window style available, which matters during August when your air conditioner is running the meter overtime. At TruePane we set each casement with a specific attention to the hinge-side reveal, because a casement that sags by even 1/8 inch will start scraping the sill frame within a year. Our technicians adjust the hardware after setting, test-cycle each sash a dozen times, and register both manufacturer warranty layers before leaving your driveway.

Awning Windows
Awning windows hinge at the top and open outward from the bottom, which means you can leave them cracked open during an afternoon rain without inviting water onto the floor. We install a lot of these in Stuart laundry rooms, bathrooms, and above kitchen sinks where a horizontal opening makes more sense than a tall sliding sash. The key with an awning window is the top hinge seal - if the seal is not bedded true, wind-driven rain from a summer squall will find its way inside. We bed every awning window with a continuous top seal and test each unit with a water wand before we call the job done.

Fixed & Picture Windows
Fixed and picture windows don’t open, and that’s the point: they frame the view without a single mechanical part to fail. In Stuart, these are the windows facing the St. Lucie River, the golf course, or the preserve behind the house where an operable sash would just add cost and a leak point. We install them with the same perimeter flashing detail as operable units, because a non-opening window leaks exactly the same way as one that opens when the rough opening is out of true. For large picture windows, we verify the header and sill deflection before ordering glass so the unit doesn’t twist under its own weight.

Single & Double Hung
Single and double hung windows slide vertically within a track, with the double hung allowing both the top and bottom sash to move. These remain the most common replacement in Stuart’s older neighborhoods, where a double hung fits the existing window opening without major framing work. We set double hungs with level jambs and even side reveals so the sash doesn’t bind when the humidity swells the wood trim in July. Every double hung we install gets a sash-balance test before we call it complete, because a window that won’t stay open is a warranty claim waiting to happen.

Sliding Windows
Sliding windows run on a horizontal track and work well in wide openings where a crank-out unit would block a walkway or patio. We’ve installed plenty of them in Stuart homes where the window faces a covered lanai and the homeowner wants ventilation without a sash swinging into conversation space. The critical part is the sill track - we slope it slightly toward the outside and verify the weep holes drain before we set the sash. A sliding window that puddles on the track during a rainstorm was installed with a flat sill, and that’s a fix we do not leave for later.

Bay & Bow Windows
Bay and bow windows project outward from the wall, usually with a center fixed unit flanked by operable casements (a bay) or a gentle arc of four to six units (a bow). They add floor space by illusion, create a reading nook, and bring in light from three angles at once. The installation is more involved - we build a support frame under the projection that carries the load down to the foundation, and we insulate the floor cavity so the window seat doesn’t become a cold draft zone. These are jobs where a mismeasured rough opening compounds quickly, so we measure every bay and bow opening three times before ordering glass.

Brands We Service for Window Installation
PGT windows are the most common impact-rated line we install in Stuart, and we’ve set hundreds of PGT WinGuard and SpectraGuard units in homes from North River Shores to Rocky Point. We know PGT’s flange systems, their glazing tape specifications, and how the tempering marks read on their laminated glass. When a PGT window fails, it’s usually because someone cut a corner on the fastening schedule or missed a shim point - not because the unit was bad out of the box. We follow PGT’s installation specs to the letter so the warranty doesn’t get voided by a shortcut.
We also install a large volume of CGI impact windows for Stuart homeowners who want the heaviest frame section in the catalog. CGI builds a thick aluminum frame that handles larger spans without reinforcing, which matters on big picture windows facing the water. For vinyl-framed window installations, we regularly work with Ply Gem and CWS lines, particularly their single hung and sliding models that match well with existing vinyl siding trim. Whether you have a PGT, CGI, Ply Gem, CWS, or any other make in mind - or you’re not sure what brand suits your home and budget - we’ll sit down with you and quote manufacturer lines side by side on paper so you can see exactly what you’re buying.
Signs You Need Window Installation Right Now
- Your windows fog between the panes. That cloudiness in the glass means the insulated seal has failed and the inert gas between the panes has leaked out. You can’t polish it away. A window with failed seals is now insulating at roughly a single-pane level, and in Stuart’s humidity, it will only get worse.
- Your sashes stick or refuse to stay open. When a window binds, the frame has shifted or the balances have worn out. You might be living with a window that falls shut on your hands, which is both a nuisance and a hazard. A properly installed replacement stays open at any position and closes with one hand.
- You feel a draft even when the window is locked. Air moving around a closed window means the weatherstripping has compressed or the frame is no longer square in the opening. In Stuart, that draft carries moisture, which feeds condensation and, eventually, wood rot in the jamb.
- Your windows are original to a home built before 1994. That’s the year Florida’s building code started requiring stronger wind resistance in residential window assemblies. A pre-1994 window in Stuart has survived storms on luck, not engineering. A modern impact-rated installation changes what happens to your living room during the next hurricane warning.
- Caulk and paint are all that’s holding the frame together. When you can see patchwork around the exterior trim, someone has been managing the decline instead of fixing it. Every layer of caulk traps water behind it eventually. We remove old frames down to the rough opening and install the new window with proper flashing, not a heavier bead of silicone.
Our Window Installation Process - Step by Step
Step 1: The Phone Call
You call (754) 324-4646 and a live person answers. No menu tree, no callback form. We listen to what you’re dealing with - the draft, the fogged glass, the window that won’t close - and we schedule a time for a measurement visit. This first call usually takes under ten minutes.
Step 2: The Measure and Quote
A background-checked, uniformed technician arrives on time and measures every opening twice, including the diagonal dimensions that reveal if a rough opening is out of square. We walk you through manufacturer line options side by side on paper, with written prices for each. No vague verbal estimates. The quote you receive is the price you pay - no surprise line items on the invoice.
Step 3: The Order
Once you approve the quote, we place the order with the manufacturer and confirm lead times in writing. This is where a lot of contractors go quiet. We don’t. You’ll know when your windows are scheduled for production, when they ship, and when we’ll be back to install them.

Step 4: The Install
On install day, we protect your floors, remove the old windows carefully, inspect the rough opening for water damage or rot, and flash the new unit exactly as the manufacturer requires - no shortcuts on the fastening schedule, no skipped shims. We clean the glass, test every operable unit, and haul the old windows away.
Step 5: The Walk-Through and Paperwork
Before we leave, we walk every window with you and register both manufacturer warranty layers in writing. You get written confirmation of the warranty durations and our Done Right Promise on the workmanship. If something isn’t right in the first 90 days, we make it right - no paperwork fight, no arguing. That’s the Keystone Standard.
How Much Does Window Installation Cost in Stuart?
A typical single hung or sliding window installation in Stuart runs $450-$800 per window for a standard vinyl unit, including labor. Casement windows run $650-$1,100 each because the hardware and multi-point locking system add cost. Bay and bow window installations are the most variable, typically $3,500-$8,000 for the full assembly including support framing and interior trim. Impact-rated windows from PGT or CGI start around $900 per window and climb based on glass package and frame finish.
What drives the price in Stuart specifically is the impact requirement, the condition of your existing rough openings, and whether any interior trim needs to be rebuilt after removal. Older Homes in White City or Port Salerno sometimes need sill repair before a new window can be set properly, and that work gets quoted in writing before we start - never as a surprise on the final invoice. You avoid overpaying by getting a line-item quote that separates materials from labor, by confirming the warranty registration in writing, and by choosing a company that doesn’t charge for a second visit because the first measurement was wrong. Our estimates are free, and the price we quote is the price on the final bill. Call (754) 324-4646 to schedule yours.

Frequently Asked Questions - Window Installation in Stuart
Window installation is the process of removing old window units and setting new ones into the existing rough opening, properly flashing, insulating, and trimming them so they operate correctly and seal against water and air. It includes measuring the opening, ordering the unit, preparing the frame, setting the window square and level, and registering the warranty. That last step gets skipped by a lot of crews, but it’s part of our Keystone Standard on every job.
Most standard window installations take one day for 8-10 windows once the units arrive. A whole-house replacement of 20 or more windows typically takes two to three days. Bay and bow windows or custom openings add a half day each. We’ll give you a written timeline at the quote stage so you can plan around the work.
Window installation in Stuart averages $450-$1,350 per standard window, with impact-rated units starting around $900 and running higher based on glass and frame. A full home replacement typically falls between $6,000 and $24,000. The final price depends on window type, brand, the condition of your rough openings, and the glass package.

Once your windows arrive, we’ll get you on the schedule and the actual install happens in a day or two.

Additionally, the manufacturer’s warranty on the glass and frame stays intact because we install to their written specifications.
Clear a three-foot workspace inside the house around each window, remove curtains or blinds, and take pictures or mirrors off the walls that share a frame with the window. Move furniture back where possible, and clear outdoor access to the windows being replaced. We protect your floors with drop cloths and clean the glass and the work area before we leave. Our technicians handle furniture moving only for items directly in the work path - everything else should be moved ahead of time.
