What makes Sewall’s Point different from Stuart, Jensen Beach, or anywhere else on the mainland is the salt. The town sits on a narrow peninsula with the St. Lucie River wrapping the west side and the Indian River Lagoon running the east edge. That means every home on the island gets hit with salt-laden air from all four directions, year-round. There is no protected side of the house. We spec windows for that reality from the first measurement.

Our Window Installation Services in Sewall’s Point
Every window we install on the peninsula is specified to handle 360-degree salt air, High-Velocity Hurricane Zone wind loads, and the humidity that sits on this island like a damp towel. Here’s what we install most often for Sewall’s Point homeowners:
Casement Windows
Casement windows are common in Sewall’s Point’s 1960s and 1970s custom homes, and they fail here faster than almost any other style because the crank hardware sits close to the exterior face where salt deposits build up. We replace them with marine-grade stainless hardware and Impact Windows & Doors in Sewall’s Point frames, usually in PGT or CGI lines, so the crank turns smooth ten years later. A typical casement replacement in Sewall’s Point runs $900-$2,100 per unit, installed.
Single & Double Hung Windows
Single and double hung windows on the peninsula suffer most from balance and jamb corrosion, because the vertical track channels give salt-laden air a place to settle. We often find the original aluminum balances have seized or snapped when homeowners try to open windows they haven’t touched in years. On a 1980s custom home off South Sewall’s Point Road, our crew pulled original single-pane aluminum units and found the rough openings rotted from years of salt-driven moisture intrusion. We framed back to sound lumber, laid down full-width flashing tape, and set PGT impact-rated casement windows with fusion-welded frames. The owner no longer sees salt haze on the interior glass after every storm. Single and double hung replacements in Sewall’s Point typically run $800-$1,900 per opening.
Fixed & Picture Windows
Fixed and picture windows are the primary view windows on Sewall’s Point, and they’re also the primary leak point when sealant fails between the frame and the stucco. The view of the St. Lucie River or the Indian River Lagoon comes with a cost, and it lands on the glazing. We re-glaze picture windows with impact-rated laminated glass and full perimeter flashing, so your view stays clear and your drywall stays dry. Fixed window replacement in Sewall’s Point runs $700-$2,400 per unit depending on glass size and whether the opening needs reframing.
Sliding Windows
Sliding windows face the same balance and track issues as double hungs, but with a larger glass area that collects more salt deposit. The tracks corrode from the bottom up, scoring the rollers and making the sash stick. We replace the full frame with thermally broken aluminum or vinyl rated for HVHZ wind zones. Sliding window installation in Sewall’s Point runs $850-$2,200 per opening.

Common Window Installation Problems We See in Sewall’s Point Homes
- Seal failure from salt-laden air. High ambient humidity and saline deposition accelerate insulated glass unit seal degradation. The result is fog between the panes, even on north-facing windows, often within 15-20 years of installation. On Sewall’s Point, that timeline shrinks because the air is corrosive on every exposure.
- Undersized or out-of-square openings. Many 1960s-1990s custom homes on the peninsula have non-standard window openings or jambs that have settled out of square over decades. Swapping in modern impact-rated units frequently triggers reframing and code-mandated upgrades, which we identify during the initial measurement so the contract reflects the work from the start.
- Improper or deteriorated flashing. Because nor’easters and southeast Atlantic breezes hit all four elevations, inadequate flashing on any side of the house leads to water intrusion behind the siding, rotting the jamb and sash corners. We pull the old flashing, inspect the sheathing, and lay new full-width flashing tape before the new window goes in.
- Corroded hardware and seized balances. Original aluminum frames from the 1970s and 1980s pit on all sides of a Sewall’s Point home. The crank mechanisms, balances, and locking hardware degrade even when the glass itself is intact. Replacement hardware gets specified in marine-grade stainless or corrosion-resistant composites.

FAQs - Window Installation in Sewall’s Point
The St. Lucie River wraps the entire west side of the peninsula, and salt-laden air off the river corrodes window frames and hardware on that elevation nearly as aggressively as the lagoon side. Unlike mainland Stuart where one side of the house sits protected from direct marine exposure, Sewall’s Point homes get hit from all four directions because there is no inland buffer. We see pitting and seal failure on north- and west-facing windows at nearly the same rate as ocean-facing exposures. Call (772) 218-5890 and we’ll send a tech out to assess your specific openings.
The most common surprises are rotten rough openings from decades of salt-driven moisture intrusion, out-of-square jambs that require reframing, and outdated flashing that has cracked away from the stucco. We often find that the original builder sealed the window directly to the masonry without any peel-and-stick flashing, which means water has been working its way behind the frame for 40 years. We identify these conditions during the initial measurement and write the repair scope into your contract before work starts. If a surprise still shows up once the old window comes out, you approve any additional cost in writing before we touch it.
Sewall’s Point sits inside the Florida High-Velocity Hurricane Zone, so any replacement window must meet HVHZ impact-rated standards and the design pressure requirements for Martin County. Standard Miami-Dade impact products may pass, but we recommend marine-grade HVHZ systems on the peninsula because the salt-air factor degrades standard hardware and seals faster here than it does a few miles inland. We quote both options on paper and show you exactly what each one covers.
On the mainland, a quality Energy-Efficient Windows in Sewall’s Point insulated glass unit generally holds its seal for 20-25 years under normal Florida conditions. On Sewall’s Point, where elevated humidity and saline deposition run constantly on all four elevations, we typically see seal failure between 12 and 18 years, with older aluminum-framed units failing sooner. The marine environment accelerates the breakdown of the desiccant and sealant that keeps the argon gas in and moisture out. If you’re starting to see fog or a hazy film between the panes, that’s a failed seal, not something that wipes off. Call (772) 218-5890 and we’ll tell you whether it’s worth reglazing or time for a full replacement.
When a window replacement in Sewall’s Point requires a permit, Martin County code upgrades go with it, typically for opening protection, flashing details, and anchor requirements that didn’t exist when the house was built. We pull the permit, schedule the inspection, and pass it before we call the job done. The permit line items are written into your contract so there’s nothing added after the fact. A window job that triggers structural reframing may also require a structural engineer’s letter, which adds $400-$600 to the scope. We’ll tell you upfront, in writing, whether your project triggers that requirement.
