Sewall’s Point is not like mainland Stuart, and window work here is not interchangeable with work a mile inland. The town is completely ringed by the St. Lucie River and Indian River Lagoon. That means every home on the island, not just the waterfront estates, sits inside Martin County’s most aggressive salt-air corrosion zone. We build every quote around that reality, not around a generic Florida window template. Our Window Installation team knows what holds up out here and what fails early, and we’ll tell you the difference before you spend a dollar.

Key Takeaways for Sewall’s Point Homeowners

• Every Sewall’s Point home sits in the peninsula’s salt-air corrosion zone, which shortens the life of aluminum frames and hardware compared to mainland Martin County.
• Replacement windows must meet current Martin County wind-load and impact requirements for the Florida Building Code High Velocity Hurricane Zone.
• Standard impact-rated vinyl windows in Sewall’s Point run $850-$2,400 per opening installed; casement and large fixed-picture units run higher.
• Documented impact compliance can protect your insurance claim history and may affect your premium after a replacement.
• TruePane registers both manufacturer warranty layers in writing before the truck leaves your driveway.

Why TruePane Windows & Doors Is Sewall’s Point’s Preferred Window Installation Company

We’re not the cheapest bid on this island, and we don’t try to be. Homeowners here tend to have been in their houses for twenty or thirty years, and they’ve had a bad window experience before: a fogged seal, a track that binds in July, a contractor who never answered the phone again. That’s who we work for. TruePane was founded by second-generation glazier Dale Kessler in 2008, and the company is built on the founding rule that still sits on the whiteboard: if the pane is not true, the job is not done.

Sewall’s Point residents call us for a few specific reasons. We show up in uniform, background-checked, and on time. We measure every opening twice. We quote manufacturer lines side by side on paper so you can see the actual product you’re buying, not a vague line item. And we register both warranty layers in writing before the truck leaves. That’s the Keystone Standard, and the 90-Day Done Right Promise sits behind it: if it isn’t done right, we make it right. No paperwork fight, no fine print that covers neither.

We also understand the island. We know what a seized aluminum track on an eight-year-old sliding window looks like, because we’ve replaced enough of them on South Sewall’s Point Road and the adjacent streets. Dispatch and scheduling are coordinated from our Miami (South FL) office, but our crews work Sewall’s Point regularly enough to know the neighborhood roads without a map.

You’ll find our work around town, and you’ll find a company that sponsors county fairs and church roof funds. We plan to be doing this in thirty years. That’s the difference between a local glazier and a franchise that will be gone after the storm season ends.

Our Window Installation Services in Sewall’s Point

Casement Windows

Casement windows seal tighter against wind-driven rain than any other operable style, which matters on a peninsula where the wind comes off the lagoon from multiple directions. A high-quality impact-rated casement window in Sewall’s Point typically runs $1,100-$2,800 per opening installed, depending on size and glass package. We use fusion-welded vinyl frames and marine-grade hardware with stainless steel hinges and multi-point locks. If your current casement cranks are pitted from salt, we’ll show you exactly what failed and what we’re putting back in its place.

Sliding Windows

Sliding windows are common in Sewall’s Point homes built between the 1960s and 1990s, and the tracks are the weak point. Salt-laden humidity builds along the bottom rails, aluminum oxidizes, and within eight to twelve years, the sash stops moving. Our replacement sliding windows use reinforced vinyl frames and stainless track rollers designed for coastal exposure. Installed cost for a standard impact-rated sliding window in Sewall’s Point falls in the $850-$2,200 range. We also service and replace existing sliding glass doors, which on this island fail on the same corrosion timeline.

Single & Double Hung Windows

Many older Sewall’s Point homes have original single-pane aluminum hung windows that are both corroded and non-compliant with current Martin County code. We replace them with impact-rated single or double hung vinyl units that carry the proper design pressure rating for this wind zone. A standard single hung in Sewall’s Point runs $850-$1,900 installed; double hungs run higher when you’re adding an elevated sill or custom sizing. The difference in air sealing alone is dramatic, especially on the St. Lucie River side where the prevailing breeze finds every gap.

Fixed & Picture Windows

Fixed windows are the workhorses for the view properties on this island, and Sewall’s Point has some of the most valuable sightlines on the Treasure Coast. A large impact-rated picture window in Sewall’s Point can run $1,500-$4,500 installed depending on the glazing package, which is worth understanding clearly before you sign. We quote low-E glass with argon fill and the correct lamination for impact resistance, and we’ll show you the difference between a PG 50 and PG 70 rating. The point is not just the view; it’s keeping that glass where it belongs in a hurricane.

Trusted Brands We Service in Sewall’s Point

TruePane is an authorized installer for more than a dozen manufacturer lines, including Andersen, Pella, Marvin, Milgard, Jeld-Wen, PGT, CGI, and ES Windows. For Sewall’s Point specifically, we stock and install more PGT, CGI, and Simonton product than anything else, because those lines carry the impact ratings and coastal hardware packages this peninsula demands. We quote manufacturers side by side on paper so you see the engineering behind each line, not just a name on a bid. We register both warranty layers in writing before the crew leaves your driveway.

Common Window Installation Problems We See in Sewall’s Point Homes

• Salt corrosion on aluminum frames and tracks. Homes on this island, even those built in the 2000s, often show pitting and seized rollers within eight to twelve years. The lagoon air hits every elevation and every exposure with no interior neighborhood as a buffer.
• Seal failure and fogged insulated glass. Constant salt-laden humidity works its way into the glazing pocket, and once the argon fill escapes, the U-factor drops. You’ll see condensation between the panes that you can’t wipe off from either side.
• Original single-pane aluminum windows that no longer meet code. Many Sewall’s Point homes built from the 1960s through the early 1990s retain the original jalousie or aluminum-framed windows. Hurricane Frances and Jeanne in 2004 pushed Martin County to strengthen impact-rating enforcement, and these older openings simply do not pass inspection.
• Sliding glass door tracks seized from salt. We find doors on homes just 8-12 years old that will not open without shoulder pressure. The failure timeline surprises mainland homeowners, but any tech who works Sewall’s Point expects it and plans for it.

How Wind-Load Requirements Shape a Sewall’s Point Window Installation

Sewall’s Point sits inside the Florida Building Code’s High Velocity Hurricane Zone, and replacement windows must meet specific design pressure ratings tied to your exact location on the peninsula. The rating your window must carry is not optional, and it’s not a suggestion printed on a brochure. It’s the engineering requirement that governs whether your opening passes a Martin County inspection after installation.

A compliant quote for Sewall’s Point includes the design pressure rating on the product cut sheet, the lamination and glazing package that supports that rating, and the installation method that anchors the frame to your existing opening. A cheap quote leaves those details out, and the savings disappear the first time an inspector flags a window, or an insurance adjuster asks for the paperwork and you don’t have it.

Here’s what you need to know: a window with a lower design pressure rating on the leeward side of the peninsula might fail the same code requirement as a higher-rated unit on the St. Lucie River exposure. We measure every opening, calculate the wind-load factors for your specific address, and document what we installed and why. That documentation is what an insurance carrier wants to see when you file a future claim.

How Documented Impact Compliance Affects Your Insurance

When we replace a window in Sewall’s Point, we document the design pressure rating, the lamination, the installation method, and the inspection result. That paperwork matters. Homeowners who file a windstorm claim after a hurricane are often asked for proof that their openings were impact-rated and code-compliant at the time of the loss.

We replaced a 1990s-era aluminum sliding window on South Sewall’s Point Road where the track had seized from salt corrosion, and the original single-pane glass failed the Martin County impact-rating requirement. Our crew installed a fusion-welded, impact-rated vinyl casement window with low-E glass and argon fill, then used flashing tape to seal the jamb against wind-driven rain. After inspection, the homeowner’s insurance carrier accepted the documented compliance, which protected their claim history. That’s the Keystone Standard in practice, and it’s what we do on every job on this island.
