Trusted Window Replacement for Stuart Homeowners
Window replacement in Stuart typically costs between $550 and $1,400 per window for standard double-hung units, and most whole-home projects run $8,000 to $22,000 depending on frame condition, glass package, and whether you’re upgrading to impact-rated units. We’ve been replacing windows in Martin County homes since 2008, and we know which units hold up to salt air, which frames warp in August humidity, and which installation shortcuts cause fogged seals two years down the road. Our crews do it right the first time, register both warranty layers in writing before the truck leaves your driveway, and stand behind every job with our Done Right Promise. If you’re noticing drafts, sticking sashes, or condensation between panes, call (754) 324-4646 and we’ll schedule your free on-site estimate.

What Our Window Replacement Service Includes
Every window replacement job in Stuart starts with the same question: what’s the condition of the rough opening? The answer determines whether you need a full frame replacement, an insert, or something in between. We don’t guess, and we don’t sell you a package you don’t need. Here’s how each type of replacement works and when it applies.
Full Frame Replacement
Full frame replacement removes the entire existing window down to the studs: frame, sill, casing, everything. This is the right call when the original frame is rotting, termite-damaged, or out of square, which we see regularly in older Stuart neighborhoods like Poppleton Creek and North River Shores where wood frames have spent thirty years absorbing coastal moisture. TruePane cuts back the opening, corrects any framing issues, installs new construction-grade flashing, and sets the new window plumb and true. Most full frame replacements in Stuart run $900-$2,200 per window depending on glass package and whether the unit is impact-rated.

Insert Window Replacement
Insert replacement, sometimes called pocket replacement, fits new sashes and a new frame inside the existing opening while leaving the original frame intact. You’d choose this when the frame is solid, square, and dry, but the glass seals have failed or the hardware is worn out. It’s faster, less invasive, and generally runs $550-$900 per window for standard vinyl inserts. We measure every opening twice before ordering, because a quarter-inch gap in an insert translates to drafts and air leaks that defeat the purpose of replacing the window in the first place.

Storm Window Replacement
Storm window replacement is for Stuart homeowners who have exterior storm units over single-pane primary windows and want to upgrade the storm layer without rebuilding the entire opening. It’s common in post-war homes around Port Salerno and White City where the original windows are still solid but the storms are dented, fogged, or no longer seal. We replace the storm sash and reglaze or replace the tracking, and we’ll tell you honestly if upgrading the primary window to a modern insulated unit would serve you better long-term. Storm sash replacement typically runs $200-$500 per window depending on size and material.

Energy-Efficient Upgrade
An Energy-Efficient Upgrade replaces dated single-pane or aluminum-frame windows with double-pane or triple-pane low-E units designed for South Florida’s heat index. In Stuart, where air conditioning runs ten months a year, low-E glass with argon fill can cut solar heat gain enough to reduce cooling bills by 15-30% in older homes. We quote manufacturer lines side by side on paper so you see the exact U-factor, SHGC, and warranty terms before you spend a dollar. Expect to pay $700-$1,500 per window installed for double-pane low-E units.

Historic Window Restoration
Historic Window Restoration is for homes in Stuart’s designated historic districts and older Florida cracker or Mediterranean Revival styles where replacement would compromise the home’s character or violate local preservation guidelines. We restore sashes, replace broken muntins, reglaze glass, rebuild counterweights, and install inconspicuous weatherstripping that preserves the window’s original appearance. Dale Kessler learned the trade from his father, and that includes knowing when a window should be restored rather than replaced. Restoration work is quoted per window because the condition varies so widely, but most restorations fall between $400 and $1,200 per sash.

Brands We Service for Window Replacement
We’re an authorized installer for more than a dozen manufacturer lines, and we stock OEM parts and hardware for the brands most common in Stuart homes. PGT is the brand we set most often in Martin County coastal runs because their WinGuard impact-rated aluminum and vinyl lines are tested and Miami-Dade approved, and they hold up to the salt air along Sewall’s Point and the St. Lucie River. We’ve set hundreds of PGT impact windows and register every warranty layer with PGT’s own documentation before the truck leaves the driveway.
CGI and CWS are our other go-to impact lines for homeowners who want maximum storm protection with laminated glass that’s engineered for Cat 5 wind speeds. For budget-conscious replacements where impact rating isn’t required, we set Ply Gem vinyl windows and can answer questions about their frame construction and thermal performance against the Florida sun. Whether you have PGT, CGI, CWS, Ply Gem, or any other make, we’ll quote your exact window side by side with its closest comparable so you know what you’re paying for. Our home page lists the full lineup, but the short version is this: if it’s a window, we replace it.
Signs You Need Window Replacement Right Now
- Condensation between the panes. Fogged glass means the seal has failed and the insulating gas has escaped. Once the seal is gone, the window’s thermal performance drops dramatically and the only real fix is glass replacement or a full unit swap. We see this constantly in Stuart homes where the original builder-grade windows are 15-20 years old.
- Drafts you can feel near the window. Run your hand around the sash and frame on a windy day. If you feel air moving, the weatherstripping is shot or the frame has shifted out of square. That draft is costing you real money in cooling every month from May through October.
- Sashes that stick, bind, or won’t stay open. Wood frames swell in Stuart’s summer humidity, which means sticking windows aren’t just annoying, they’re a sign the frame has absorbed moisture and is beginning to fail. If the window binds in July, the frame needs to be addressed, not just lubricated.
- Visible rot, soft wood, or crumbling sills. Tap the sill and frame with a screwdriver handle. If it sounds hollow or gives, you’ve got rot or termite damage. This is the most urgent warning sign because a rotted frame is a structural issue, not a cosmetic one, and it will only spread.
- Your energy bills keep climbing without explanation. Old single-pane or failed-seal windows let heat pour in all day, forcing your AC to work harder. Replacing them with low-E double-pane units is one of the few home improvements that pays for itself in measurable monthly savings.
Our Window Replacement Process - Step by Step
- 1
Free on-site estimate and measurement. A background-checked TruePane technician comes to your Stuart home, measures every opening twice, and inspects the frame, sill, and rough opening for rot, termite damage, or alignment problems. We bring sample windows and quote manufacturer lines side by side on paper so you can compare U-factor, SHGC, and warranty terms in writing.
- 2
Written line-item proposal. Within a day or two of the estimate, you get a fixed price with no change orders, no surprise line items, and no vague allowances. The quote spells out the exact window, glass package, frame material, hardware, and warranty terms for every opening. What we quote is what you pay.
- 3
Ordering and manufacturer verification. We order directly from the manufacturer or authorized distributor and verify every unit’s dimensions, glass specs, and warranty registration paperwork before scheduling the install. If you choose impact-rated windows, we confirm Miami-Dade or FBC approval numbers so your insurance company gets the documentation they need for premium credits.
- 4
Installation day. Our uniformed technicians arrive when we say and protect your floors, furniture, and landscaping before removing the first window. Every unit is set plumb, level, and square, flashed correctly, insulated, and trimmed. We clean up every day before we leave, hauling off old windows and glass unless you want to keep anything.
- 5
Warranty registration and walkthrough. Before the truck leaves your driveway, we register both manufacturer warranty layers in writing and hand you a folder with every warranty duration stated in plain English. We walk the job with you window by window to make sure every pane is true, every sash operates smoothly, and every question is answered. If anything’s not right, the Done Right Promise means we come back and make it right. No paperwork fights. No arguing.
How Much Does Window Replacement Cost in Stuart?
A typical insert window replacement in Stuart runs $550-$900 per window for standard vinyl double-pane units. Full frame replacement runs $900-$2,200 per window depending on the frame material, glass package, and whether the unit is impact-rated. Whole-home projects for a 1,500-2,000 square foot house typically fall between $12,000 and $28,000 when you’re replacing 15-20 windows with mid-grade vinyl or aluminum frames. Impact-rated windows from PGT or CGI run $1,200-$2,500 per window installed and often qualify for insurance premium reductions that offset part of the cost. Historic restoration and custom glass work is quoted per window because no two old windows are in the same condition.

The biggest factors that affect price are the window size, frame material (vinyl is most economical, aluminum and wood run higher), glass package (double-pane is standard, triple-pane and laminated glass add cost), and whether you choose impact-rated units. Labor in Stuart is steady year-round, but material costs fluctuate with the market. We give you a written line-item quote so you see exactly what each window costs before you commit.

Frequently Asked Questions - Window Replacement in Stuart
Window replacement is the removal of an existing window unit and installation of a new one, either as a full frame replacement down to the rough opening or an insert that fits inside the existing frame. The right choice depends on the condition of your current frame, sills, and rough opening. A full frame replacement is necessary when the frame itself is compromised; an insert works when the frame is solid and only the sashes and glass need replacing.
Most window replacement projects in Stuart take one to two days for a standard single-story home with 10-20 windows. A full house replacement can run three to five days depending on the number of openings and whether there’s frame repair involved. Insert replacements are the fastest, often done in a single day. We’ll give you a realistic timeline in writing before we start.
