Fast, Reliable Custom Windows & Doors Across Port St. Lucie
Custom window and door work in Port St. Lucie starts with one question most companies never ask: was your house built by General Development Corporation? If it was, and if it still has the original jalousie windows, your replacement quote needs to include masonry buck work or the install will not pass St. Lucie County inspection. We know this because we see it on nearly every original GDC home we touch west of US-1. Call (772) 279-7983 and we’ll walk through what your specific house needs.
Why TruePane Windows & Doors Is Port St. Lucie’s Preferred Custom Windows & Doors Company
TruePane Windows & Doors has served Port St. Lucie homeowners since 2008 through a craft tradition that goes back to founder Dale Kessler, a second-generation glazier. We’re not a franchise operation. We hire local technicians, train apprentices into journeymen, and sponsor county fairs and church roof funds in Port St. Lucie because we plan to be here in thirty years. Our Custom Windows & Doors team works on the original GDC tract homes off Floresta Drive and Port St. Lucie Boulevard as often as on the newer subdivisions around Tradition and Gatlin Boulevard. That range matters. The construction quirks in each era are different, and a crew that has never opened a CBS wall without a wood buck will underbid the job or fail the inspection, or both.
Every estimate is a square deal: written line-item quotes, side-by-side manufacturer comparisons on paper, and both warranty layers registered before the truck leaves the driveway. We stand behind the work with the Done Right Promise. If the pane is not true, the job is not done. A live person answers the phone 24 hours a day, seven days a week. Not a voicemail tree. Not a callback form.
Our Custom Windows & Doors Services in Port St. Lucie
Custom Shape Windows
Port St. Lucie has no shortage of arched, radius, octagon, and eyebrow windows, especially in homes built during the 1980s and 1990s boom. A custom shape cut to the wrong radius leaves you with a rough opening that leaks water into the CBS wall and a window that binds when the humidity rises. We template every opening twice before ordering, and we fabricate custom-shaped impact-rated units that fit the existing buck, or build a new one where none exists. A typical custom shape window in Port St. Lucie runs $900 to $2,800 per opening depending on size, glass package, and whether we need to rebuild the buck. Call (772) 279-7983 for a written quote.

Oversized Glass Panels
Oversized panels are common in Port St. Lucie’s newer homes around Tradition, where great rooms face west into the afternoon sun. The glass package matters more than the frame on these openings. We specify low-E laminated insulated glass rated for St. Lucie County’s wind zone, and we have installed panels large enough to require a crane, usually on custom builds and commercial storefronts. The salt air near the Indian River Lagoon will pit cheap aluminum hardware on these panels within five to seven years. We specify stainless hardware. Expect $2,500 to $8,000 per oversized panel in Port St. Lucie, installed, depending on size and glass package.

Architectural Grilles & SDLs
Simulated divided lites give a Port St. Lucie home the look of true muntins without the maintenance of individual panes. We are often asked to match the existing lite pattern on a street of GDC-era homes along Floresta Drive or Port St. Lucie Boulevard, and we template the original pattern so the new SDLs match the old sightlines. Grilles between the glass on impact-rated units cost $40 to $90 per window, while true SDLs run higher depending on the lite count and profile. The Keystone Standard applies here: you see the grille pattern, the glass package, and the warranty durations in writing before the job starts.

Commercial Storefront Glazing
We also serve commercial storefronts along the US-1 corridor and the newer retail strips off Gatlin Boulevard. Storefront glazing in Port St. Lucie must meet the same wind-borne debris code as residential work, and insurance inspectors are just as strict. We install aluminum storefront systems with impact-rated glass, replacement doors, and handle commercial service calls with the same live-answer phone policy. Commercial storefront replacements typically run $65 to $140 per square foot in Port St. Lucie depending on the framing system and door hardware.

Curtain Wall Systems in Port St. Lucie
Curtain wall work in Port St. Lucie is usually commercial or high-end custom residential, and it is the most structural glazing we do. Salt air from the Indian River Lagoon gets into every mullion joint and anchor point. We use marine-grade finishes and stainless fasteners on every curtain wall we install in St. Lucie County, and we pull permits and schedule St. Lucie County inspections ourselves. A curtain wall replacement in Port St. Lucie starts around $12,000 for a small storefront elevation and runs upward from there based on the framing system, bracketing, and glass. We quote it line by line, on paper.
Trusted Brands We Service in Port St. Lucie
We install and service Port St. Lucie jobs for more than a dozen manufacturer lines including Andersen, Pella, Marvin, Milgard, Jeld-Wen, PGT, CGI, and ES Windows. In Port St. Lucie specifically, PGT and CGI are the two names homeowners ask about most because both lines are made in Florida and built around the impact-rating requirements the insurance market here enforces. We also work with Simonton and Ply Gem for replacement projects where the homeowner wants proven impact-rated windows without moving up to a premium line. We carry local service parts for common PGT and Simonton hardware so a sash replacement or roller swap does not wait on a warehouse in Tampa.
Common Custom Windows & Doors Problems We See in Port St. Lucie Homes
- Jalousie windows set directly into CBS block. The original GDC homes from the 1960s through the 1980s rarely have wood bucks around the window openings. Replacing a jalousie with an impact-rated unit requires fabricating and anchoring a pressure-treated buck into the masonry first. We see this on nearly every original GDC house we touch in west Port St. Lucie, and out-of-area bids routinely miss it.
- Salt-air pitting on aluminum frames and hardware. Homes within a mile of the Indian River Lagoon lose aluminum frames to oxidation and pitting within seven to ten years. We see jambs that seize, sash pivots that shear, and rollers that grind to dust. The fix is marine-grade finish and stainless hardware, not another coat of spray paint.
- UV-degraded vinyl seals and gaskets. South and west facing elevations in Port St. Lucie get brutal afternoon sun. Vinyl window seals, foam gaskets, and exterior caulk fail within seven to ten years here, often well inside the manufacturer’s rated lifespan. Fogged insulated glass is the tell. We replace failed IGUs and re-glaze openings with components rated for our UV load.
- Undersized or missing bucks on custom replacements. We have opened walls off Floresta Drive and found the original window screwed directly into block with no structural framing at all. Any replacement installed the same way will fail St. Lucie County wind-load inspection. It is the single most common reason a cheaper Port St. Lucie bid ends up costing more than ours within a year.
Pricing for Custom Windows & Doors in Port St. Lucie, FL
Here is what custom window and door work actually costs in Port St. Lucie, without the vague ranges.
| Service | Typical Port St. Lucie Price Range |
|---|---|
| Custom shape window (impact-rated) | $900 - $2,800 per opening |
| Oversized glass panel (impact-rated, +80″ side) | $2,500 - $8,000 per panel |
| Architectural grilles / SDLs (upgrade) | $40 - $90 per window (between-glass); SDLs higher by lite count |
| Jalousie-to-impact replacement with new masonry buck | $1,100 - $2,400 per opening depending on opening size and glass |
| Complete GDC-era home window replacement (12-16 openings) | $14,000 - $32,000 all-in with bucks, trim and stucco repair |
The buck work is the difference between a Port St. Lucie quote from us and a Port St. Lucie quote from an out-of-area company. A pressure-treated buck install into a CBS opening adds $300 to $600 per opening in labor and materials. A company that does not know to include it will come in low, then either abandon the job or install the window unsupported. We include it in every quote on the original GDC homes, in writing, from the first line. Call (772) 279-7983 for an exact quote. Estimates are free.
We Also Serve Cities Near Port St. Lucie
Our crews work throughout St. Lucie County and the northern Treasure Coast, including Vero Beach, South Beach, Vero Beach South, and West Vero Corridor. The same salt-air and UV conditions apply along the lagoon side of these cities, and the same insurance-mandate environment drives most replacement work. Call (772) 279-7983 and we’ll let you know when a crew is in your area.

FAQs - Custom Windows & Doors in Port St. Lucie
Jalousie windows remain in Port St. Lucie because the original GDC tract homes were built with them from the early 1960s through the 1980s, and owners often put off replacement because the openings are set directly into CBS block without wood bucks, which makes the job more labor-intensive than a standard swap. Yes, they can be replaced with custom impact-rated units. The opening must first receive a pressure-treated buck anchored into the masonry, then the new unit installs into that buck and passes St. Lucie County wind-load inspection. At TruePane, that buck work is in every quote from the first line. Call (772) 279-7983 for a free estimate.
Brackish salt air within about a mile of the Indian River Lagoon accelerates aluminum oxidation and hardware pitting dramatically, often visible as white corrosion within five to seven years. The same air eats vinyl seals, foam gaskets, and caulk on south and west elevations, leading to fogged insulated glass. We specify marine-grade finishes and stainless hardware on lagoon-adjacent work. A standard inland aluminum frame that lasts twenty years in Orlando may need replacement here within eight. We’d rather quote the marine-spec version up front than see the cheap version fail inside a decade.
Because St. Lucie County is the only county in Florida to have taken direct hits from two major hurricanes in a single season (Frances and Jeanne in 2004), most Port St. Lucie homeowners cannot get or renew property insurance without documented impact-rated windows and doors. Replacement windows on GDC homes must be impact-rated and installed per Florida Building Code requirements, which for original jalousie openings means a pressure-treated buck in the CBS rough opening. We pull permits and schedule St. Lucie County inspections, and both warranty layers are registered in writing before the truck leaves the driveway.
Yes, custom-shaped windows can be fabricated with impact-rated laminated glass and frames certified for the Florida Building Code wind zone. Arches, radius, octagons, eyebrows, and angled openings are all feasible, but the shape of the structural frame usually governs whether a non-operable fixed unit is required and what glass package you can choose. A custom-shaped impact unit costs more than a standard rectangular one because the frame is cut and welded to the template rather than pulled from inventory. We template every opening twice. Call (772) 279-7983 and we’ll tell you what your shape can handle, on paper.
Expect roughly a two-to-one difference. Standard aluminum frames on homes within a mile of the Indian River Lagoon show visible pitting and hardware binding within seven to ten years, while marine-grade finishes and stainless hardware typically last fifteen to twenty years in the same conditions. The difference is not cosmetic; pitted frames bind, jambs seize, and sash pivots shear. We quote marine-grade for lagoon-adjacent work because the cheap spec costs more within a decade once you factor in a second replacement. Call (772) 279-7983 for a written quote on either spec.
