Fast, Reliable Impact Windows & Doors Across Sewall’s Point
Impact window and door replacement in Sewall’s Point runs $1,800-$4,200 per opening for most custom homes, with high-end architectural glass and marine-grade hardware pushing $6,000-$9,000 per unit. That’s the honest range for this island, where salt-laden lagoon air meets Martin County’s most stringent hurricane-impact code. Every home here, not just the waterfront lots, sits inside a salt-corrosion zone that mainland Stuart homes a mile west never experience. If you’re a Sewall’s Point homeowner wondering why your sliding glass door seized shut at year nine or why your windows fog between panes, that’s what we fix. Call (813) 320-9346 for a free estimate with pricing locked in writing before any product is ordered.
Why TruePane Windows & Doors Is Sewall’s Point’s Preferred Impact Windows & Doors Company
Sewall’s Point is a town where people remember the contractor who left them with a fogged seal and a door that binds in July. That’s the customer we’ve worked for since Dale Kessler founded TruePane in 2008. The work is done under Impact Windows & Doors specifications that meet current Martin County code, and our crews know the island well enough to forecast what’s failing before you notice it.
We don’t run a call center. A live person answers the phone 24 hours a day, 7 days a week, which matters when you’re standing in front of a seized 12-foot slider that won’t budge. Our 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 and what it costs before anything is ordered. That’s not a promise we wave around. It’s the Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before the truck leaves your driveway. We stand behind it.
Our Impact Windows & Doors Services in Sewall’s Point
Sewall’s Point’s housing stock is dominated by custom and semi-custom single-family homes built between the 1960s and 1990s, with a newer wave of large luxury builds from the 2000s and 2010s. The older homes frequently retain original single-pane aluminum sliding glass doors and jalousie or aluminum-framed windows that are now both corrosion-compromised and non-compliant with current code. The newer homes were built better, but the island’s salt-humidity cycling still works on their seals and hardware. Here’s how we handle the four areas that matter most on this peninsula.
Hurricane Impact Windows in Sewall’s Point
Most homes we work on along South Sewall’s Point Road and the lagoon-facing streets off Heritage Way were built before Hurricane Frances and Hurricane Jeanne hit Martin County in 2004. Those storms accelerated local code enforcement, and what passed inspection in 1998 does not pass today. We install fusion-welded impact-rated windows with low-E argon-filled glazing, and we register both warranty layers before we leave. For a 3,000-square-foot custom home, full replacement typically runs $28,000-$55,000 depending on the number of openings and the manufacturer line you choose.

Impact Sliding Glass Doors in Sewall’s Point
This is the single most common failure we see on the island. Sliding glass door tracks on homes just 8-12 years old are often already seized with salt corrosion, a timeline that surprises homeowners who moved from inland Florida but is immediately recognizable to any tech who has worked Sewall’s Point. The lagoon air hits every elevation and every exposure on this peninsula with no buffer. We replace seized sliders with Sewall’s Point Sliding & Patio Doors that are impact-rated and fusion-welded, using marine-grade stainless steel rollers and hardware. A typical 12-foot impact sliding glass door replacement runs $4,500-$8,500 installed, depending on the frame material and glass package.

Impact Entry & French Doors in Sewall’s Point
Front entries on Sewall’s Point homes face a harder environment than most owners realize. Salt-laden humidity cycles through the day, expanding and contracting door slabs and corroding hinges and thresholds on a compressed schedule. We install impact-rated entry and Custom Windows & Doors in Sewall’s Point with marine-grade hardware and butyl flashing at the rough opening, which is the layer that keeps water out of the jamb. A custom impact French door set for a Sewall’s Point entry typically runs $3,200-$7,500, with designer hardware and specialty finishes pushing higher.

Impact Garage Doors in Sewall’s Point
Garage doors on this island are a weak point in the building envelope. Older homes off Montego Road and River Road often have non-impact-rated garage doors with corroded tracks and springs. We replace them with rated impact garage doors that meet Martin County’s wind-load requirements. A single impact-rated garage door replacement on Sewall’s Point runs $3,500-$6,800, depending on the door size, insulation, and track hardware. If the springs still carry tension, leave them alone. High-tension garage door springs can cause serious injury if handled by someone without the right training and tools.
We also handle hurricane shutters and protection systems, wind mitigation inspections, and the code-compliance paperwork Martin County requires after a storm-hardening upgrade. If you’re planning a remodel or a sale, a wind mitigation report can change your insurance numbers. We pull the permits and coordinate the inspections so you don’t carry that burden.

Trusted Brands We Service in Sewall’s Point
TruePane is an authorized installer for more than a dozen manufacturer lines, and on Sewall’s Point, the ones that earn their keep are Andersen, Pella in Sewall’s Point, and Marvin. Each has marine-grade hardware options and impact-rated glazing packages that hold up on this island. We stock local parts for common failures, but the big truth on Sewall’s Point is that high-end work runs on product lead times, not on how fast a crew can swing hammers.
That’s a candid point and it matters. Lead times, not labour, set the calendar on this tier of work. Custom millwork, architectural glass, and specialty finishes take weeks to fabricate, sometimes longer when supply chains tighten. We fix the price in writing before we order any product, and we don’t change it once the order is placed. A square deal.
Common Impact Windows & Doors Problems We See in Sewall’s Point Homes
- Salt-laden lagoon air pits aluminum frames and corrodes sliding glass door tracks within a decade. Homes under 15 years old regularly show up with sliding doors seized shut, even when the same hardware on the mainland would have another ten years of life. The peninsula’s full encirclement by the St. Lucie River and Indian River Lagoon means there is no interior neighborhood where hardware is safe.
- Original 1960s-1990s single-pane aluminum and jalousie windows fail current Martin County hurricane-impact code. Many are corroded at the sash corners and can’t be retrofitted economically. The right fix is full replacement with rated impact windows, and the cost difference between retrofitting and replacing is often smaller than owners expect once the corrosion scope is visible.
- Insulated glass unit seals fail prematurely from constant salt-humidity cycling. Fogging between panes signals seal failure and argon loss, which kills the energy performance of the window. On Sewall’s Point, this shows up on every elevation, not just the waterfront side, because the lagoon air wraps around the entire island.
- Non-impact-rated garage doors and entry doors leave the building envelope open to wind and water. After Frances and Jeanne tore through Martin County in 2004, code requirements tightened, but homes built before that often still carry original non-rated openings. Those are the ones that fail first in a storm and cost the most in unplanned repairs after.
Pricing for Impact Windows & Doors in Sewall’s Point, FL
Here’s the honest range for Sewall’s Point work. A typical impact window replacement runs $1,800-$4,200 per opening. Impact sliding glass doors run $4,500-$8,500 for a 12-foot unit, depending on frame material and glass. Impact entry and French door sets run $3,200-$7,500. Impact-rated garage doors run $3,500-$6,800. For a full home package on a larger custom build, expect $28,000-$55,000 or more when architectural glass, custom millwork, and designer hardware are in the scope.
What drives the number? The manufacturer line you choose, the size and number of openings, the hardware finish (marine-grade stainless holds up best on this island), and whether your home needs full frame replacement versus insert replacement. Seized aluminum sliders in older homes often require full frame tear-out and re-flashing, which adds labor but prevents the next decade of rot and corrosion. We provide free estimates with fixed pricing in writing, and we don’t change the number once the work starts. Call (813) 320-9346 to schedule your free estimate.

FAQs - Impact Windows & Doors in Sewall’s Point
Sewall’s Point is a narrow peninsula entirely enclosed by the St. Lucie River and Indian River Lagoon, so every home sits inside Martin County’s most aggressive salt-air corrosion zone, with no interior buffer. Salt-laden humidity attacks aluminum tracks, rollers, and hardware continuously, and failures that take twenty years on the mainland often arrive here in eight to twelve, which is why Sewall’s Point Glass Railing Systems and other exterior features need marine-grade protection. The fix is replacement with marine-grade stainless hardware, and the sooner you catch it, the less damage to the frame and subfloor. Call (813) 320-9346 for an assessment, free estimates included.
No. Original jalousie and single-pane aluminum windows from the 1960s through 1990s do not meet today’s Martin County hurricane-impact requirements, and most have corroded at the sash corners to the point where retrofitting is uneconomical. Full replacement with rated impact windows is the standard path, and the price difference between retrofit and replacement is often minimal once the corrosion scope is on the table. Call (813) 320-9346 to get a written line-item quote.
Salt-humidity cycling expands and contracts the seal material around insulated glass units, and once that seal fails, the window fogs between the panes and loses its argon fill along with its energy performance. On Sewall’s Point, this shows up on every elevation because the lagoon air hits every side of every home. Fogging means the seal has already failed and the unit needs replacement, not cleaning. Call (813) 320-9346 for an inspection, and we’ll register the replacement warranty in writing before we leave.
Marine-grade stainless steel is the standard for this island. Standard aluminum or zinc hardware corrodes quickly in the lagoon air, while powder-coated finishes chip and then corrode underneath. Marine-grade stainless resists pitting and salt adhesion far longer. We spec it on every exterior door and window hardware package we install on Sewall’s Point. Call (813) 320-9346 to see the hardware options on paper, side by side.
Product lead times drive the schedule. Custom millwork, architectural glass, and specialty hardware are made to order, and fabrication windows run weeks, not days, on this tier of work. Labor is the easy part on the calendar. We lock pricing in writing before we order any product, and we sequence the long-lead items first so the job doesn’t stall waiting on one window. Call (813) 320-9346 and we’ll walk you through what’s realistic for your project.
