Fast, Reliable Window Replacement Across Palm Beach
Window replacement in Palm Beach typically runs $800 to $1,500 per impact-rated window installed, with whole-home packages starting around $8,000 and large custom openings reaching $2,500 to $5,000. Every opening on this barrier island has to clear two gates at once: Florida’s coastal wind-load design pressure for impact-rated glazing and the Town’s Architectural Commission (ARCOM) review of sight lines, divided-lite patterns, and exterior profile details. We’re Westlight Windows & Doors, and our Window Replacement team has navigated both gates on Mizner-era estates, mid-century moderns, and everything in between. If you’re weighing a replacement, call (903) 354-7134 and we’ll talk through what your specific home actually needs.

Why Westlight Windows & Doors Is Palm Beach’s Preferred Window Replacement Company
Palm Beach homeowners hire us because we show up in the window we gave, leave the job site cleaner than we found it, and put every price and promise in writing before a single screw turns. That’s the Kingswell Guarantee, and it applies to every job we do on the island, from a one-window glass swap in a Phipps Plaza condo to a full-frame replacement on a 1920s estate near the ocean. Owen Satterfield leads our crews, and he’s built the company since 2009 on a simple rule: if it’s not done right within the guarantee period, we come back and fix it at no charge. No negotiating, no revised invoices, no door-step surprises.
Our customers in Palm Beach tell us the same thing they told the contractor who let them down before us: they want a real human on the phone, a written price, and a crew that treats their 1940s stucco walls and original casement openings with respect. We staff our phone lines with a live person 24 hours a day, 7 days a week, not a voicemail box. When you call (903) 354-7134, a person answers. That matters at 9 p.m. when a storm is three days out and you’re staring at a window that won’t seal.
We’re an independently owned and operated Kingswell location, and we run local crews who know Palm Beach’s permitting rhythm with ARCOM and the Landmarks Preservation Commission. That local knowledge isn’t something a mainland shop can fake. It’s the difference between a permit that clears in weeks and one that stalls for months over a visible gasket detail.
Window Glass Replacement in Palm Beach
Window glass replacement in Palm Beach usually means swapping a cracked or fogged pane in an otherwise sound frame, and on this island that pane almost always has to be impact-rated laminated glass matched to the opening’s design pressure. We see it constantly in Palm Beach: a golf ball from the Breakers course, a branch in a summer squall, or a failed seal between panes that leaves condensation you can’t wipe away from either side. The fix costs $250 to $600 per pane on most standard openings, and it’s almost always a one-day job once the glass arrives.
What a Palm Beach homeowner should know is that glass replacement here is not a hardware-store pane swap. The replacement lite has to carry the same Miami-Dade NOA or Florida Product Approval as the original unit, and on many Mizner-era openings the glass has to sit in the frame with a concealed or wet-glazed detail so the exterior sight line still reads as the original putty-glazed profile. Get that wrong and ARCOM will bounce the permit.
Impact Glass to Match Originals
On older Palm Beach estates, original casement glass was thin and putty-set. Modern impact laminated glass is thicker and heavier, so we match the sight line by choosing the right interlayer and edge profile for the frame. It’s a small thing that review boards actually look at.
Fogged Seals and Salt Haze
Salt air off the Atlantic and the Intracoastal accelerates seal failure in double-pane units, especially on east-facing openings in the 33480 zip. When the seal fails, you lose the insulating gas and the glass fogs. Replacing just the glass, not the whole frame, is the cost-effective fix we recommend when the frame is still square and solid.
Window Sash Replacement in Palm Beach
Window sash replacement in Palm Beach means replacing the moving part of the window, the frame that holds the glass, while keeping the original outer frame in place. It’s the right call when the glass is cracked or the sash is warped, rotted, or seized, but the surrounding frame and stucco opening are still sound. On the island, we most often do sash replacement on 1950s and 1960s mid-century homes and condos with large single-pane aluminum sliders along the Intracoastal side of Palm Beach. Expect to pay $400 to $900 per sash depending on size and impact rating.
The appeal is real: you save the stucco, save the trim, save the permitting hassle that comes with full-frame tear-outs, and you still get a brand-new impact-rated sash that meets current wind-load codes. The catch is that the existing frame has to be level and square enough to accept a new sash, which we verify during the free in-home measure.
When the Frame Stays and the Sash Goes
We see this on Royal Poinciana Way condos and along South Ocean Boulevard: original frames set into concrete or hollow-tile walls that would be expensive and invasive to remove. A new sash drops into the old opening, the sight line changes little, and the job is done in a day.

Why Salt Air Chews Sash Hardware
Palm Beach’s salt-laden air, present on both the ocean and lagoon sides of the island year-round, corrodes sash hardware faster than anything on the mainland. We replace the hardware with marine-grade or corrosion-resistant components whenever we rebuild a sash, because a new sash with old, pitted hardware will bind within a couple of years.
Trusted Brands We Service in Palm Beach
We carry and install window lines from PGT, CGI, CWS, ES Windows, and ECO Window Systems, which means we match the product to the job instead of forcing one brand onto every opening. PGT and CGI impact units dominate on Palm Beach’s east-facing estates and high-wind parcels. ECO Window Systems gives us the thermally broken, narrow-profile frames that ARCOM favors on Mizner-era homes because they read closer to original steel. We also service and replace existing units, and we keep local parts access for Palm Beach customers so a broken sash or failed seal doesn’t mean waiting on a slow supply chain. You get the right glass, the right frame metal, and the right look for your block and your board review.
Common Window Replacement Problems We See in Palm Beach Homes
- ARCOM rejection over visible black rubber gaskets. Standard impact frames use exposed rubber glazing gaskets, but Mizner-era windows were putty-glazed with thin sight lines. ARCOM routinely rejects those standard frames, and homeowners end up paying for redesign and waiting months. We spec concealed or wet-glazed narrow-profile frames from the start.
- Missing Miami-Dade NOA or Florida Product Approval paperwork. An impact window installed without its approval documentation cannot be used to claim the wind mitigation credit under Florida Statute 627.0629, so your insurer treats compliant glass as non-compliant. We hand you the paperwork at completion, every time.
- Corrosion from salt air on both sides of the island. Every parcel in Palm Beach sits between the Atlantic and the Intracoastal, and salt spray attacks aluminum extrusions, hardware, and thresholds year-round. Standard mainland-grade aluminum fails early here. We spec marine-grade finishes and stainless hardware where the exposure demands it.
- Original steel casements that have seized or rusted through. Crittall-style steel windows from the 1920s through 1940s are beautiful but rarely repairable once the steel swells inside the masonry. We reset thermally broken impact frames into those hollow-tile openings without tearing up the surrounding stucco.
Pricing for Window Replacement in Palm Beach, FL
Most Palm Beach homeowners spend $800 to $1,500 per window on impact-rated replacement units, installed. Impact single-hung windows run $900 to $1,800. Large, custom, or historically sensitive openings, the kind you see on the lakefront estates and along Worth Avenue, land between $2,500 and $5,000 each. Whole-home packages typically start around $8,000 and climb past $25,000 for a full estate with custom divided-lite impact patterns. What moves the price on this island: the opening’s design pressure, the floor height above grade, the frame material, whether ARCOM requires a custom mullion or sight-line detail, and how many openings are on the water side of the house. We give every Palm Beach customer a free in-home measure and a written quote before any work starts.

What Window Replacement Costs in Palm Beach
You’ll see numbers above, but here’s the straight version. Impact windows in Palm Beach run $800 to $1,500 per window installed. Impact single-hung units are $900 to $1,800. Large or custom openings, the kind that need matched sight lines and concealed gaskets for ARCOM, cost $2,500 to $5,000. Whole-home packages range from $8,000 to over $25,000. What moves the number: the wind zone your parcel sits in, the floor height of the opening, whether the frame is standard aluminum or a thermally broken narrow profile, and how many openings face the water. The free in-home measure gives you a written quote that locks those numbers before any work begins. That’s the Kingswell Way: say the price before the work.
Florida Pays You Back
Palm Beach homeowners have three real incentives stacked in their favor. First, the My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, including impact windows and doors. Second, Florida gives a sales-tax exemption on impact-resistant windows and doors, which takes real money off the invoice. Third, the federal 25C energy credit covers 30% of the product cost, up to $600 per year, on qualifying energy-efficient units. On top of that, many Palm Beach homeowners see windstorm-premium credits averaging around 25% on the windstorm portion of their policy after a wind-mitigation inspection, which runs $75 to $150. We can’t guarantee what your insurer or the programs will approve, but we make sure the documentation is in order so the credits can stick. Impact windows also beat hurricane shutters for one simple reason: the protection is permanent, and there are no panels to haul out and hang when a storm is 48 hours out.

FAQs About Window Replacement in Palm Beach
Yes. Palm Beach sits in a coastal wind zone where design pressures run higher than inland West Palm Beach or Greenacres, and every replacement opening on the island needs impact-rated glazing with a Miami-Dade NOA or Florida Product Approval matched to the specific opening’s design pressure. We calculate that per opening and show you the rating on the written quote. Call (903) 354-7134 for a free measure if you want to know your parcel’s number.
ARCOM rejects impact units when the exterior sight lines don’t match the original Mizner-era glazing, most often because standard frames use black rubber glazing gaskets visible from outside. Original windows were putty-glazed with razor-thin profiles. We spec thermally broken, narrow-profile impact frames with concealed or wet-glazed gaskets so the replacement reads like the original, and that clears the review. It’s the dual-compliance problem, and most contractors don’t see it until the permit stalls.
It can, but only if the units carry the proper Miami-Dade NOA or Florida Product Approval and you complete a wind-mitigation inspection, which runs $75 to $150. Windstorm-premium credits average around 25% on the windstorm portion of the policy. We hand you the approval paperwork for every opening at job completion so your insurer can’t treat the glass as non-compliant.
Yes, and it’s a job we’ve done many times on Mediterranean Revival estates off Worth Avenue and along South Ocean Boulevard. The original Crittall-style steel casements are usually beyond repair once they’ve rusted inside the masonry, but we reset thermally broken impact frames with concealed gaskets into the original hollow-tile openings. The sight line matches, the divided-lite pattern matches, and ARCOM signs off.
Salt air from the Atlantic and the Intracoastal corrodes standard aluminum extrusions and hardware far faster on Palm Beach than on the mainland. We spec marine-grade finishes and stainless hardware on exposed openings, and we avoid frame materials that pit and bind within a few years. It’s one of the reasons a cheap mainland quote doesn’t hold up out here. Call (903) 354-7134 for a written quote built for this island’s conditions.
