Fast, Reliable Window Replacement Across Sewall’s Point
Window replacement in Sewall’s Point is a different job than it is anywhere else in Martin County. The peninsula sits with the Indian River Lagoon on one side and the St. Lucie River on the other, so salt air works on every elevation of your house at all hours. Replacement windows here need to meet Florida’s impact-glazing code and stand up to hardware corrosion that inland homes never see. TruePane Windows & Doors handles full-house replacements, impact-rated upgrades, and historic window restoration for Sewall’s Point homeowners who expect the work done right the first time. Call (754) 238-2201 for a free estimate, and we’ll send a background-checked, uniformed technician to measure, quote, and explain your options on paper.
Why TruePane Windows & Doors Is Sewall’s Point’s Preferred Window Replacement Company
We work in Sewall’s Point regularly, and the condition we find on nearly every job is predictable: east and west elevations of the same house corrode at nearly identical rates. There is no sheltered side on this peninsula, so we plan for whole-house work from the start. Homeowners here tell us they want a company that answers the phone and stands behind the work in writing. That is how Dale Kessler built TruePane: a second-generation glazier who started out of the principle that out-of-true installs and voided warranties were problems worth fixing permanently. Every job carries the Done Right Promise and The Keystone Standard, which means both manufacturer warranty layers get registered in writing before our truck leaves your driveway. No paperwork fights. No arguing.
Sewall’s Point homeowners also tell us they are tired of contractors who quote one thing and bill another. Our pricing is fixed and written before we order anything. We quote manufacturer lines side by side on paper, including Andersen, PGT, and CGI, so you see exactly what you are buying and why. Our crews live and work in South Florida. We plan to be here in thirty years, which is why a live person answers our phone 24 hours a day, 7 days a week. Not a voicemail tree. Not a callback form.
Our Window Replacement Services in Sewall’s Point
Every Window Replacement project in Sewall’s Point starts with a walkthrough of your home and a conversation about how long you plan to stay, what has failed before, and which elevations are showing the worst salt damage. We then recommend the approach that matches your house and your budget. Here are the four services Sewall’s Point homeowners ask us about most.
Full Frame Replacement
Full frame replacement is the standard recommendation in Sewall’s Point, and for good reason. Original aluminum frames on 1960s through 1980s custom homes have pitted and oxidized after decades of direct salt exposure. Swapping the sash alone, which is what an insert does, leaves the rotted or corroded frame in place. Full frame replacement removes everything down to the rough opening, lets us inspect and reseal the perimeter, and installs a complete new unit rated for Martin County’s wind zone. On a peninsula, that is the difference between a window that lasts twenty years and one that fails in eight.

Insert Window Replacement
Insert replacement works when the existing frame is still sound and square. That is less common in Sewall’s Point than in mainland Stuart, but some 1990s and 2000s homes with early-generation impact frames can take inserts. We measure every opening twice, check the frames for hidden corrosion at the corners and sill, and tell you honestly if an insert is a smart long-term move or a short-term patch. We will not sell you an insert that we would not put in our own mother’s house.

Storm Window Replacement
Storm window replacement in Sewall’s Point carries a particular burden: the product has to handle wind-driven rain, salt spray, and hurricane pressure. Many homes here have old storm units that predate current Florida Building Code impact ratings. We replace them with code-compliant impact-rated storm windows, using stainless or marine-grade hardware on every operator. The salt air does not give you a grace period, and neither does the building inspector.

Energy-Efficient Upgrade
An energy-efficient upgrade in Sewall’s Point usually means replacing single-pane aluminum with insulated, argon-filled, low-E impact units. The salt air that corrodes your frames also shortens the life of insulated glass seals. Fogged panes are common on nearly every elevation. We specify argon-filled, low-E glass with warm-edge spacers that hold up better in the marine environment, and we register the thermal performance warranties in writing. On a custom home with thirty or forty openings, the cooling savings alone often justify the project.

Trusted Brands We Service in Sewall’s Point
We are an authorized installer for more than a dozen manufacturer lines, and the ones we quote most often in Sewall’s Point are, PGT, CGI, and ES Windows. PGT and CGI build impact-rated units specifically for Florida’s coastal wind zones, and we stock the common replacement parts and hardware for these lines so we are not waiting on a distributor when a homeowner needs a repair. Sewall’s Point homeowners frequently ask us to compare Andersen’s architectural lines against PGT’s impact series side by side, and we do that on paper, with prices, before you commit.
Common Window Replacement Problems We See in Sewall’s Point Homes
- Salt-driven seal failure. Insulated glass units lose their argon fill prematurely when the sealant breaks down under constant salt exposure. Fogged panes and reduced insulation show up on nearly every elevation, not just the water-facing ones.
- Corroded aluminum frames on both sides of the house. East and west elevations corrode at nearly identical rates on this peninsula, so a single-side replacement plan fails within a few years as the other side degrades just as quickly.
- Outdated early-generation impact windows. High-end 1990s and 2000s homes often have impact windows that no longer meet current Florida Building Code wind-zone ratings for Martin County. Those need full replacement to maintain legal compliance and keep your insurance standing.
- Failing hardware and thresholds. Door thresholds, casement operators, and sliding tracks pit and seize in the salt air. Stainless or marine-grade components are essentially non-negotiable here, and we specify them on every job.
Pricing for Window Replacement in Sewall’s Point, FL
A full-frame impact-rated window replacement in Sewall’s Point typically runs $1,400 to $2,800 per opening, depending on the manufacturer line you choose and the condition of the rough opening. On a 1980s custom home, that usually means a whole-house project between $35,000 and $75,000. Insert replacements on sound frames run $900 to $1,800 per window. Energy-efficient upgrades with argon-filled, low-E glass typically add $150 to $350 per opening over base impact pricing. Historic window restoration, where we rebuild original wood sashes and route them for impact glass, runs $1,800 to $3,200 per window depending on the condition of the wood. What actually moves the number is not labor. It is the manufacturer’s lead time and the product line. We fix the price in writing before we order, so you never get a surprise line item when the truck arrives. Call (754) 238-2201 for a free, line-item estimate.
What Actually Controls the Schedule for a High-End Window Replacement on Sewall’s Point
On high-end work in Sewall’s Point, lead times set the calendar. Not labor. Impact-rated units from PGT and CGI are often running ten to fourteen weeks from order to delivery, and architectural lines from Andersen can run longer. Custom millwork, specialty glass, and bronze or stainless hardware add weeks on top of that. Our team coordinates directly with your architect or designer, orders everything at contract signing, and builds the installation schedule backward from the delivery date. We will tell you the real timeline up front, not the one that sounds good in a sales pitch.
We recently replaced a full set of original aluminum-frame single-panes on a 1980s custom home off South Sewall’s Point Road. The lagoon-facing and river-facing sashes both had pitted, oxidized frames and multiple seal failures, so we installed impact-rated, marine-grade casement and double-hung units from Andersen, with stainless hardware and argon-filled low-E glass. The project moved on the manufacturer’s long lead time, not our crew’s schedule, and the fixed price was agreed in writing before we ordered. That is how we handle every high-end job on the peninsula.

FAQs - Window Replacement in Sewall’s Point
Yes. Martin County’s wind zone requires impact-rated glazing on every elevation of the house, not just the water-facing sides. Florida Building Code does not distinguish between a neighbor’s house and a hurricane windfield. Plus, on a peninsula, salt air hits every side year-round, so the neighbor-facing windows corrode just as fast as the river-facing ones. Call (754) 238-2201 and we will confirm exactly what code requires for your specific address.
Plan on two to three times faster corrosion than inland Stuart. The salt-laden air wraps around the entire peninsula, so aluminum tracks, casement operators, and thresholds on both east and west elevations pit and seize within a decade on non-marine hardware. Inland Stuart homes may get fifteen to twenty years. Stainless or marine-grade components are the only sensible choice here, and we specify them on every Sewall’s Point job. Call (754) 238-2201 for an estimate that includes marine-grade hardware by default.
Because there is no sheltered side on this peninsula. East and west elevations corrode at nearly identical rates, so replacing only the river-facing windows means you will be back for the lagoon-facing ones in a few years, and you will pay mobilization and permitting costs twice. Full-house replacement lets us lock in a fixed price, order everything at once, and avoid the staggered lead times that drag a single-side project across two hurricane seasons. Call (754) 238-2201 and we will walk the property with you and show you what the frames actually look like.
Yes, and this is one of the reasons we keep historic window restoration and architectural coordination in-house. Original 1960s custom homes in Sewall’s Point often have unique mullion patterns, deep wood sashes, and proportions that off-the-shelf vinyl cannot match. We rebuild original wood sashes, route them to accept impact glass, and install them with custom millwork so the house reads the same from the street, but meets today’s wind-zone code. Anderson and Marvin both offer architectural lines that replicate mid-century proportions, and we quote them side by side on paper. Call (754) 238-2201 and bring your original plans if you have them.
Manufacturer lead times control the schedule, not our labor. Impact-rated units from PGT and CGI commonly run ten to fourteen weeks from order to delivery. Architectural lines from Andersen and custom millwork can add more. If you want the windows installed before hurricane season, we need to order in February or March, not June. We coordinate with your architect or designer, place the order at contract signing, and give you a written schedule with real dates. Call (754) 238-2201 and we will map out a realistic timeline for your specific product choices.
