Fast, Reliable Window Replacement Across Sewall’s Point
Window replacement in Sewall’s Point, FL runs $900-$2,800 per opening for impact-rated units, with full-frame tear-outs landing on the higher end of that range and insert replacements clustering lower. Most jobs in this town require Martin County Wind-Borne Debris compliance, which means laminated impact glass and reinforced frames are the baseline, not an upgrade. If you’re calling from a 1960s ranch along South Sewall’s Point Road or a newer rebuild near the St. Lucie River, the conversation starts with salt corrosion and ends with a written quote. Call (954) 280-4413 and we’ll walk the house with you.
We’re TruePane Windows & Doors. Dale Kessler started this company in 2008 on a rule that still hangs in our shop: if the pane is not true, the job is not done. Sewall’s Point is a different animal from Stuart or Jensen Beach, and we’ll tell you why in plain terms below.
Why TruePane Windows & Doors Is Sewall’s Point’s Preferred Window Replacement Company
We’ve been into enough Sewall’s Point homes to know what the peninsula does to a window. The town sits completely surrounded by brackish water, the St. Lucie River on the west and the Indian River Lagoon on the east. That means every house here lives in salt air, all day, every day. Aluminum frames pit. Jamb screws turn to powder. Weatherstripping gives out years before the manufacturer’s datasheet says it should. A company that only knows inland installs will sell you a unit rated for Orlando and wonder why it fails in ten years here.
Our crews show up background-checked and uniformed, and they measure every opening twice. We quote manufacturer lines side by side on paper so you can see exactly what you’re buying and what it costs. We’re an authorized installer for more than a dozen lines, including PGT, CGI, and ES Windows. Every quote includes The Keystone Standard: both warranty layers registered in writing, durations stated, before the truck leaves your driveway. And the Done Right Promise covers the workmanship with no paperwork fights and no arguing.
We train apprentices into journeymen and act like a company that plans to be in Martin County thirty years from now. That matters when you’re spending five figures on impact windows and you want a phone number that still rings in 2035.
Our Window Replacement Services in Sewall’s Point
A full Window Replacement project in Sewall’s Point usually means impact-rated glass, marine-grade hardware, and a schedule driven by manufacturing lead times, not labor. Here’s what we handle most often in town.
Full Frame Replacement
When the existing frame is corroded, rotted, or out of square, a full frame replacement is the only honest fix. In Sewall’s Point, we see 1950s and 1960s aluminum frames where the sill has pitted through and the jamb screws have disintegrated. We pull the entire unit down to the rough opening, square it up, flash it properly, and set a new impact-rated frame. A full-frame replacement in Sewall’s Point typically runs $1,400-$2,800 per opening depending on size and manufacturer.

Insert Window Replacement
If the existing frame is still structurally sound, an insert replacement fits a new window inside the old frame. It’s faster, less invasive, and costs less. But in Sewall’s Point, salt air doesn’t give many frames a pass. We’ll inspect the jamb and sill before we quote an insert. If the frame is even marginal, we’ll tell you straight, because a ten-year-old insert in a twenty-year-old corroded frame is a bad investment. Inserts here typically run $900-$1,800 per opening.

Storm Window Replacement
For the original ranch homes in Sewall’s Point that haven’t been updated since Hurricane Frances and Jeanne came through Martin County in 2004, we sometimes install interior or exterior storm windows as a stopgap while the homeowner budgets for full impact replacement. Be clear about this: a storm window is not a code-compliant impact unit. If your house is in the Wind-Borne Debris Region, and every house in Sewall’s Point is, a storm window won’t satisfy the code requirement on its own. We’ll tell you what does.

Energy-Efficient Upgrade
Replacing single-pane aluminum with low-E, argon-filled impact glass changes the house. The UV filtering alone spares your furniture and floors, and the thermal break ends the July heat gain through west-facing glass that faces the lagoon. In Sewall’s Point, the same humidity that corrodes your hardware also loads your air conditioning. A properly sealed Energy Star impact unit drops that load. Energy-efficient upgrades here typically run $1,100-$2,400 per opening, and the utility savings start the month the glass goes in.

Trusted Brands We Service in Sewall’s Point
We’re authorized installers for CGI, PGT, ES Windows, and we work on most major lines already in Sewall’s Point homes. For this town specifically, we lean toward manufacturers that offer marine-grade hardware options and reinforced finishes. CGI and PGT both build impact units that hold up better in a corrosive brackish environment than standard builder-grade lines. We keep common hardware and seal components stocked for local customers, which cuts turnaround time when a lock set fails on a unit that’s only twelve years old. If you own a window from a brand we don’t list, call anyway. We’ll match it or tell you honestly what it will take.
Common Window Replacement Problems We See in Sewall’s Point Homes
- Aluminum frame corrosion at the jamb and sill. Constant saltwater air from the St. Lucie River and Indian River Lagoon pits aluminum frames and turns fasteners to powder. We regularly see windows that won’t lock or won’t open because the hardware has seized inside a corroded channel.
- Fogged insulated glass from seal failure. The humidity cycling between river air and lagoon air stresses glazing seals. Once the seal fails, argon leaks out and condensation lives between the panes. In Sewall’s Point, that failure shows up years earlier than in inland Martin County homes.
- Weatherstripping and silicone seals degrading faster than rated. Manufacturer ratings assume inland air. The peninsula doesn’t cooperate. We replace weatherstripping and re-seal sashes on units that are still within their listed service life.
- Non-impact single-pane units that fail code entirely. Many original 1950s through 1970s homes in Sewall’s Point still carry aluminum single-pane windows. They’re not just energy-inefficient; they’re outside Martin County Wind-Borne Debris compliance. Any replacement has to bring them up to code.

FAQs - Window Replacement in Sewall’s Point
Sewall’s Point is the only municipality in Martin County completely surrounded by brackish water. The St. Lucie River runs along the west side and the Indian River Lagoon hugs the east. That double-water exposure drives salt corrosion at a rate comparable to a barrier island. We routinely find impact units installed only 10 to 12 years ago that already need full hardware and seal overhauls, failures that inland-tested warranty cycles never anticipated. The fix is marine-grade hardware and sealants specified from the start. Call (954) 280-4413 for an exact assessment of your windows.
Yes. Martin County sits inside Florida’s Wind-Borne Debris Region, and Sewall’s Point is fully within that zone. The code requirement has nothing to do with oceanfront frontage; it’s about wind speeds and flying debris. Every replacement window installed in Sewall’s Point must meet impact-rated glazing standards. We’ll pull the specific product approvals for your house and show them to you in writing.
Look for fogged glass between the panes, especially in the morning when humidity shifts. Run your hand along the sash edge; if you feel air movement or see silicone that’s cracked and pulling away from the frame, the seal is failing. In Sewall’s Point, even windows that look fine from the outside may be leaking air through degraded weatherstripping. We’ll do a free seal and hardware inspection and tell you what’s still serviceable. Call (954) 280-4413 to schedule it.
Sometimes, but not always. If the wood is solid and the frame is square, we can fit impact-rated laminated glass into the existing frame. In Sewall’s Point, we’ve done this on older homes where the wood jamb is still true. But if salt air or decades of humidity have rotted the frame or pulled it out of square, a glass-only swap won’t hold. We’ll tell you which path applies to your house before we quote anything.
Lead times, not labor, set the calendar on this tier. Standard-size impact units from PGT or CGI typically run 4 to 8 weeks from order to delivery. Custom or semi-custom systems, especially oversized openings on the luxury rebuilds, can run 10 to 14 weeks depending on the manufacturer’s production queue. We lock the price in writing before we order, and we coordinate the install around the manufacturer’s delivery date, not the other way around. Call (954) 280-4413 to get a realistic timeline for your specific openings.
On a 1960s ranch along South Sewall’s Point Road, our crew pulled aluminum single-pane units where the jamb screws had corroded to powder and the sash wouldn’t stay locked. The homeowner’s non-impact windows had failed Martin County’s Wind-Borne Debris code entirely, so we replaced them with fusion-welded impact-rated casements and double-hungs with marine-grade hardware. The original rough openings were out of square from decades of salt-driven frame movement, so we spent extra time flashing the new jambs with flashing tape before setting the units. That’s the work Sewall’s Point demands, and it’s the work we do.
If your windows fog, bind, or won’t lock, call TruePane Windows & Doors at (954) 280-4413. We’ll inspect them, give you a written price, and if we do the work, we’ll stand behind it for 90 days and register every warranty layer in writing before we leave. Free estimates, straight answers, done right.
