Fast, Reliable Custom Windows & Doors Across Sewall’s Point
Custom windows and doors in Sewall’s Point run $1,850 to $6,400 per opening for mid-range impact-rated lines like ECO Window Systems, and $4,200 to $14,000+ per opening for engineered architectural units from ES Windows or with most full-frame replacements done in two to three days including permit inspection. We know Sewall’s Point is different from Stuart or Jensen Beach because the salt air here works on every home, not just the ones on the river. If you’re opening up a mid-century estate or planning a remodel, call (772) 362-3326 for a free estimate and we’ll walk you through what the town’s code will and won’t allow.
What Opening Up an Older Sewall’s Point Home Actually Turns Up
Sewall’s Point is a small peninsula entirely encircled by the St. Lucie River and the Indian River Lagoon, meaning every home on the island, not just those on the water’s edge, sits in full marine salt-air exposure that destroys standard aluminum frames and door hardware within a few years. Layered on top of that, the town falls squarely within Florida’s Wind-Borne Debris Region, making impact-rated windows and doors a code requirement on any permitted replacement. That combination of corrosion pressure and hurricane code stringency distinguishes every job here from work done even a few miles inland in Stuart.
Most of the housing stock on Sewall’s Point is high-end single-family, from mid-century waterfront estates built in the 1950s through the 1970s to newer luxury custom builds. The older homes frequently retain original single-pane aluminum sliders and non-impact exterior doors that predate Martin County’s post-2004 hurricane code updates. When we open those walls, we typically find one of three things: rotted jamb and sill framing from years of weep-hole clogging and failed flashing tape, undersized headers that never should have passed inspection in the first place, or corroded frame corners so far gone the sash doesn’t seat square anymore.
Here’s how we handle it. We pull permits as full-frame impact-rated replacements on these older homes, because a glass swap almost never satisfies the current code and rarely fixes the underlying rot. We write an allowance for hidden damage into the contract before we start. If the inspector flags something adjacent, like non-impact jalousie windows that were compliant decades ago but aren’t now, we price the upgrade and wait for your written approval before touching them. No surprise change orders. No mid-project phone call asking for more money. You see the number on paper first.
One job that sticks with us was a mid-century estate off South Sewall’s Point Road. The homeowner called about a failed aluminum slider that wouldn’t lock. When our crew opened the wall, the framing behind it was soft enough to push a screwdriver through, years of salt-driven rain had eaten the flashing tape, and the sill plate needed replacing. We’d already written the allowance, so the fix was priced, approved, and done without a fight. That’s how we work on Sewall’s Point.
This is the single biggest reason a remodel quote moves on this peninsula. If you’re planning to open walls, call (772) 362-3326 for a free estimate before the drywall comes down. We’ll tell you what to expect based on the age of your house and its exposure, not what a generic quote sheet says.
Why TruePane Windows & Doors Is Sewall’s Point’s Preferred Custom Windows & Doors Company
We’ve been doing Custom Windows & Doors work long enough to know that a peninsula job is not a mainland job. The salt air here is ambient, not directional. It’s in the air on the leeward side of your house at ten in the morning. That changes how we select frame materials, how we flash openings, and which hardware we recommend. Our crews work on Sewall’s Point regularly, from the lots off South Sewall’s Point Road to the newer builds near North Sewall’s Point Road and the riverfront homes along the 34996 zip code. We know the roads, we know the permit office, and we know which inspectors are strict about the Wind-Borne Debris Region requirements.
Dale Kessler founded TruePane in 2008 after decades in the glazing trade, and the rule on his whiteboard is still the one that governs every install: if the pane is not true, the job is not done. Background-checked, uniformed technicians measure every opening twice and quote manufacturer lines side by side on paper so you see exactly what you’re buying. A live person answers the phone 24 hours a day, 7 days a week, not a voicemail tree and not a call center. When you call about a window on Sewall’s Point, you talk to someone who knows what a mitered frame corner should look like after five years of lagoon air.
Every job is covered by the Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before the truck leaves your driveway. If something isn’t right, we make it right. No paperwork fights, no arguing.
Our Custom Windows & Doors Services in Sewall’s Point
Oversized Glass Panels
Sewall’s Point homes lean hard on glass. Mid-century estates were built around wide sightlines of the St. Lucie River, and the newer custom builds push those openings even wider. Oversized glass panels on this peninsula carry two loads: hurricane wind pressure and salt air. A panel that would pass code in Orlando will flex and fail here if the frame wasn’t engineered for a marine environment. We specify impact-rated units from lines like ES Windows, and we pull the engineering on every panel over 40 square feet before it’s ordered. If the opening is oversized, the permit review takes longer, and we factor that into the schedule from day one.

Custom Shape Windows
Half-rounds, eyebrow transoms, circular ports, trapezoids over entry doors. The older Sewall’s Point estates have them, and the newer builds want them. Custom shape windows in a marine environment are where lazy fabrication shows up fast, the radius on a bent aluminum frame will oxidize at the corners if the finish isn’t up to it, and the laminated glass needs to be cut and tempered to spec, not adapted from stock. We order every custom shape as a purpose-built unit and we seal and flash the rough opening with the understanding that this island gets rain driven sideways off the Lagoon. A round window is only as good as the flashing ring behind it.

Architectural Grilles & SDLs
Simulated divided lites give a home its character, and character matters on Sewall’s Point, where the architectural review board keeps an eye on exteriors. We supply SDLs in flat or sculpted profiles, applied to impact-rated glass or factory-fabricated as true divided units with laminated lites. The mistake we see most often on peninsula homes is a homeowner or a contractor speccing a grille profile that looks right in a showroom but doesn’t match the sightlines of the original windows from 1965. We bring samples to the house and tape them in place before you commit. When the grille is wrong, the whole elevation looks wrong, and it’s a lot cheaper to know that before the windows are ordered.

Commercial Storefront Glazing
Sewall’s Point has very little commercial stock, but what exists, a few small offices and community buildings, faces the same salt and wind loads as the residences. We do storefront glazing and curtain wall systems with the same permitting discipline we bring to houses. Impact-rated storefronts, ADA-compliant door hardware, and aluminum framing with a marine-grade finish. If you manage a commercial property on the peninsula, call us and we’ll walk the building with you and tell you what the next hurricane inspection will flag.

Trusted Brands We Service in Sewall’s Point
We’re an authorized installer for more than a dozen manufacturer lines, and on Sewall’s Point we steer clients toward products that hold up in ambient salt air. ES Windows is a frequent choice for custom aluminum and wood-clad units, and their powder-coat finishes stand up to marine exposure better than most. Andersen is the steady middle path for impact-rated wood and composite windows on the older estates. ViewLux gets the call when the homeowner wants a modern, ultra-narrow aluminum frame with an impact rating. We order factory-direct, we register both warranty layers before the truck leaves, and we don’t push a line that doesn’t fit the house.
Common Custom Windows & Doors Problems We See in Sewall’s Point Homes
- Salt-air corrosion on aluminum frame corners and hardware. Weep holes clog with salt and crud, frame corners oxidize, and multi-point door lock mechanisms seize within three to five years. This is the most common call we get on the peninsula, and it’s why we steer away from standard mainland aluminum on any replacement.
- Single-pane sliders that predate the 2004 hurricane code. Homes built in the 1950s through the 1970s often still have original aluminum sliders and non-impact exterior doors. They’re not just inefficient, they’re non-compliant, and any renovation permit you pull today can trigger a requirement to upgrade them.
- Failed waterproofing behind old frames. Years of salt-driven rain working through failed flashing tape rots the jamb and sill framing behind what looks like a perfectly fine window from the outside. What starts as a fogged seal or a sticking sash becomes a full-frame rebuild once we open the wall.
- Shutter-only openings now flagged by current code. Older Sewall’s Point homes permitted with accordion or panel shutters rather than impact glass were compliant at the time. A renovation permit pulled today, even for an unrelated trade, can trigger an inspector flag requiring those shutter-only openings to be upgraded to full impact windows before the project closes. This catches homeowners and contractors off guard mid-remodel.
Pricing for Custom Windows & Doors in Sewall’s Point, FL
Here are real numbers for this market. A full-frame impact-rated replacement window in Sewall’s Point runs $1,850 to $4,200 per opening for mid-tier lines like ECO Window Systems, depending on size, mulling, and whether we’re fighting hidden rot. Custom shape windows start around $2,400 and can run past $7,000 for large radius units with true divided lites. Oversized impact glass panels run $4,500 to $14,000+, with engineering fees and permit review adding to the top end. Architectural grilles and SDLs typically add $80 to $180 per square foot of glass, depending on profile and whether the bars are exterior applied or internal between laminated lites.
What moves the number on this peninsula is hidden damage. If we open a wall and find the sill plate gone, that’s structural framing work, not window work, and we write it as a line-item change order with your approval before we touch it. You’ll never see a surprise on the final bill. Call (772) 362-3326 for a free estimate, and we’ll give you written numbers for the window, the frame, and the allowance for what’s behind it.

FAQs - Custom Windows & Doors in Sewall’s Point
Yes, it can. Martin County’s current Florida Building Code enforcement means any renovation permit pulled today, even for a kitchen remodel or a plumbing change, can trigger an inspector flag requiring shutter-only or single-pane openings to be upgraded to full impact windows before the project closes. We’ve seen it happen mid-remodel on Sewall’s Point. The fix is to call us before you pull the permit so we can assess which openings will likely be flagged and write the upgrade into your budget from the start. Call (772) 362-3326 for a free evaluation.
The peninsula is encircled by tidal saltwater on all sides, so the marine air is ambient rather than directional. In Stuart, you get salt exposure on the windward side. On Sewall’s Point, every side is the windward side, depending on the day. Weep holes clog faster, frame corners oxidize sooner, and multi-point lock mechanisms seize within a few years of installation. That’s why we recommend marine-grade finishes and stainless hardware on every replacement we quote here. A standard mainland aluminum frame will visibly corrode within three to five years on this island.
They were compliant when permitted, but they may not be now. If you’re not pulling a renovation permit, the existing installation generally remains grandfathered. The moment you pull a permit for any substantial work, the current FBC enforcement can require those shutter-only openings to be upgraded to impact-rated glazing. We see this most often on Sewall’s Point houses from the 1980s and 1990s that used accordion or panel shutters instead of impact glass. If you’re planning a remodel, call (772) 362-3326 before you file the permit. We’ll tell you which openings are at risk.
In most cases on Sewall’s Point, the whole sash goes. A fogged seal means the insulated glass unit failed, and while the IGU itself can be replaced, the surrounding frame on a peninsula home is usually corroded or out of square by the time the seal fails. We also can’t put a new IGU into a non-impact frame and call it compliant, not on this island. A full-frame impact-rated replacement fixes the fog, the corrosion, and the code issue at once. Call (772) 362-3326 and we’ll give you a written quote either way.
We write an allowance for hidden damage into the contract before we start, then price any exposure as a line-item change order with your written approval before the work happens. Rotted jamb and sill framing on a peninsula home typically adds $450 to $1,800 per opening depending on the extent of the rot and whether the header or sill plate needs replacing. You approve the number first. There’s no surprise on the back end. For an exact quote on your project, call (772) 362-3326 and schedule a free estimate.
