TruePane Windows & Doors serves Martin County’s narrow peninsula town with the understanding that every install here has to earn its place against marine-grade corrosion and Florida Building Code impact standards. When you call (754) 238-2201, a live person answers and schedules a technician who knows the difference between a lagoon-facing wall and a river-facing one because we’ve worked both sides of Sewall’s Point many times.

Why Sewall’s Point Homeowners Choose TruePane Windows & Doors
We’ve replaced windows in the waterfront estates along South Sewall’s Point Road and rebuilt door thresholds for families in the Harbor Point and Peninsula neighborhoods closer to the St. Lucie River. The homes vary in architecture, but the call usually starts the same way: a homeowner found a window track that won’t slide after another summer of salt exposure, or a patio door that binds when the humidity peaks in August. We address those problems directly with background-checked, uniformed technicians who measure every opening twice and quote manufacturer lines side by side on paper. The name TruePane comes from Dale Kessler’s founding rule: if the pane is not true, the job is not done. That rule applies to a single replacement sash and to a full-house impact retrofit.
Windows & Doors Services We Offer in Sewall’s Point
Window Installation
New construction and renovation window installation in Sewall’s Point requires product lines rated for Martin County’s wind zone and bracketed against salt-air hardware failure. We install Andersen, Pella, Marvin, and other authorized manufacturer lines with both warranty layers registered in writing before our truck leaves the driveway.
Learn more about our Window Installation in Sewall’s Point.

Door Installation
Entry doors, side doors, and sliders in Sewall’s Point wear their hardware faster than inland homes because the peninsula catches marine air from the Indian River Lagoon, the St. Lucie River, and every direction between. We install doors with marine-grade hinges and thresholds that hold square through years of humidity and coastal wind.

Window Replacement
Many homes in Sewall’s Point still carry original 1960s-1980s aluminum-frame single-pane windows that have oxidized and pitted badly in the salt environment. We replace them with impact-rated or energy-efficient glass that meets today’s Florida Building Code requirements rather than fighting them with caulk and hope. Learn more about our Window Replacement in Sewall’s Point.

Impact Windows & Doors
Impact-rated products aren’t optional in Sewall’s Point. The town sits in Martin County’s hurricane wind zone, directly exposed to systems tracking up the St. Lucie inlet, so certified impact glazing is a building code requirement. We install PGT and CGI lines with documented performance ratings and warranty registration that you’ll see in writing.

Energy-Efficient Windows
Energy-Efficient Windows - Sewall’s Point do double duty: they reduce the air-conditioning load through seven months of subtropical heat and they hold up to the salt-laden air that corrodes lesser frames. We walk you through glass packages side by side so the efficiency claims are on paper before you spend a dime.

Sliding & Patio Doors
Sliding & Patio Doors in Sewall’s Point on the St. Lucie side catch the same marine air as the lagoon-facing elevations, which means tracks, rollers, and thresholds need stainless or marine-grade components. We install and replace sliders that won’t bind in July and won’t seize after the first coastal season.

Glass Railing Systems
Glass Railing Systems in Sewall’s Point along waterfront properties share the same salt-air exposure as every window, but they also carry the constant visual duty of an unobstructed water view. We install frameless and semi-frameless railings with the proper mounting hardware for Martin County’s coastal conditions and FBC wind load requirements.

Custom Windows & Doors
Custom windows and doors for Sewall’s Point’s larger estate homes have to match the home’s architecture and outlast the coastal climate. We work from precise field measurements, not builder plans, and order custom units that fit the actual opening, not the one drawn on paper thirty years ago.

Neighborhoods We Serve in Sewall’s Point
We regularly work through the residential streets that make up this narrow town, including South Sewall’s Point Road, Harbor Point, Peninsula Drive, and the Riverview area along the western shoreline. Most jobs are scheduled within the same week in Sewall’s Point.

Why Sewall’s Point’s Climate & Housing Affect Windows & Doors
Sewall’s Point isn’t a typical coastal town. It’s a narrow land bridge with the Indian River Lagoon on the east and the St. Lucie River on the west, so every house gets marine-grade salt air from two directions at once, all year, regardless of which way the wind blows. There is no sheltered side on this peninsula. In practice, that means the aluminum-frame windows on the lagoon-facing elevation corrode at nearly the same rate as the river-facing windows on the opposite side of the same house. We regularly see pitted frames, seized tracks, and clouded seals on both elevations of the same home, which is why full-house window replacements are the norm in Sewall’s Point rather than the single-elevation jobs more common in mainland Stuart. Add Martin County’s wind-zone code requirements for certified impact glazing, and a window or door replacement in Sewall’s Point has to solve corrosion, structural wind pressure, and today’s legal standard at the same time.
Pricing for Windows & Doors in Sewall’s Point
Expect window installation in Sewall’s Point to run roughly $900-$1,800 per opening for standard energy-efficient units, and $1,700-$3,000 per opening for certified impact-rated windows and doors. Full-house replacements on the large estate homes off Sewall’s Point Road commonly fall between $25,000 and $75,000 depending on opening count, glass package, and custom sizing. Sliding and patio door replacements run $3,500-$9,000 installed, with custom corner sliders on waterfront elevations at the upper end. We quote every manufacturer line side by side on paper, with both warranty layers registered in writing before the truck leaves the driveway, and we don’t change the price after the work begins. Our home page lays out the Keystone Standard and the Done Right Promise that apply to every quote we write in Sewall’s Point.

FAQs About Windows & Doors in Sewall’s Point
Impact window replacement in Sewall’s Point typically costs $1,700-$3,000 per opening for certified units that meet Martin County’s wind zone requirements. The final number depends on the size of the opening, the glass package, and whether you choose PGT, CGI, or another authorized manufacturer line. Call (754) 238-2201 for an exact quote. Estimates are free and itemized.
Yes. Sewall’s Point is a narrow peninsula with the Indian River Lagoon on one side and the St. Lucie River on the other, and Florida Building Code impact glazing requirements apply to every elevation of the house, not just the waterfront-facing walls. There is no sheltered side on this peninsula, and corrosion from marine air attacks all sides equally, so full-house impact replacement is the standard solution.
Salt-laden air from the lagoon and river wraps around the town from multiple directions at once, and that airborne salt accelerates corrosion of aluminum frames, window tracks, and door thresholds far faster than in inland Stuart. Stainless or marine-grade hardware is essentially non-negotiable here, which is why we spec it on every Sewall’s Point install. Call (754) 238-2201 to have a technician assess what is salvageable and what is not.
No. Most homes built in Sewall’s Point between the 1960s and 1980s still carry original aluminum-frame single-pane windows that have oxidized and pitted from decades of salt-air exposure. Even if the glass is intact, the frames and tracks are often past end of life and out of compliance with today’s FBC impact glazing standards. Replacement is the fix, not window film or re-caulking.
No. We quote fixed pricing with no change orders, and both manufacturer warranty layers are registered in writing before the crew leaves the driveway. If we find unexpected rot or framing issues mid-job, we bring it to you with a clear number before doing anything, never after. Call (754) 238-2201 to schedule a free estimate and get your numbers on paper first.

What Sewall's Point Customers Say
"Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."
- Gene A."French doors to the patio, custom size because this house was built in 1961 and nothing is standard. Measured twice, three weeks to fabricate like they warned, and the install day they laid runners over my floors without being asked."
- Marie S."A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."
- Eleanor G.
