AfterFast, Reliable Window Replacement Across Palm Beach
Window replacement in Palm Beach runs $650-$2,400 per opening depending on frame type, impact rating, and whether the property carries a Town landmark designation. Most full-frame replacements on the island require Miami-Dade NOA-rated products and, for historic homes, pre-approval from the Town’s Architectural Commission before a permit is issued. We’re Sightline Windows & Doors North Palm Beach, and our crews serve Palm Beach from our Miami office, typically scheduling measured surveys within 48 hours for properties on the island. Call (561) 475-1246 to book yours.
Palm Beach isn’t like the mainland. Every home sits on a barrier island less than half a mile wide, with the Atlantic on one side and the Intracoastal Waterway on the other. Salt-laden air hits both elevations simultaneously. The housing stock skews heavily toward 1920s-1940s Mediterranean Revival and Spanish Colonial estates, many by Addison Mizner, with original steel casement windows, arched masonry openings, and heavy wood doors. These conditions create a dual compliance challenge no inland contractor faces: Florida Building Code impact and wind-load requirements, plus ARCOM historic preservation review for landmarked properties. Our Window Replacement team has handled both since 2012.

Our Window Replacement Services in Palm Beach
Full Frame Replacement
Full frame replacement in Palm Beach removes the entire existing window, including the frame, sill, and exterior trim, down to the rough opening. This is often necessary for original steel casement windows in Mizner-era homes, where the frame itself has corroded from decades of salt exposure or where the opening needs re-framing to accept modern impact-rated glazing. A typical full-frame replacement in Palm Beach runs $1,400-$2,400 per opening for impact-rated vinyl or aluminum-clad units with marine-grade finishes. Custom profiles for ARCOM-mandated historic matching can push the upper end.
Insert Window Replacement
Insert replacement fits a new window into the existing frame, preserving exterior trim and interior finishes. This works when the original frame is structurally sound and square. In Palm Beach, we see this option less frequently than on the mainland because salt corrosion often compromises the original frame itself. When conditions allow, insert replacement runs $650-$1,200 per opening. We won’t recommend it if the frame shows pitting, galvanic corrosion, or compromised sealant beds - conditions we find routinely on ocean-facing elevations in the Estate Section and along South Ocean Boulevard.
Vinyl Replacement Windows
Vinyl frames resist salt corrosion better than bare aluminum or steel, but standard vinyl isn’t sufficient for Palm Beach’s exposure. We specify multi-chamber vinyl with marine-grade hardware and stainless-steel fasteners, paired with laminated impact glass meeting Miami-Dade NOA standards. Typical range: $850-$1,600 per opening. For homes in the North End or along the Lake Worth Lagoon, we often pair vinyl frames with low-SHGC glazing to reduce solar heat gain on west-facing Intracoastal elevations.
Energy-Efficient Upgrade
Energy-efficient upgrades in Palm Beach target two problems: solar heat gain, which drives cooling loads nine months of the year, and air infiltration through failed seals in original steel units. We specify products with U-factor below 0.30 and SHGC below 0.25, typically from ECO Window Systems or ViewLux, with warm-edge spacers and argon fill. A full-home energy-efficient replacement on a 3,000-square-foot Palm Beach residence typically runs $18,000-$34,000 depending on opening count and custom profile requirements. The documented performance specs we provide support federal energy tax credit claims and, in some cases, utility rebate applications.
Window Maintenance & Care
Maintenance extends the service life of existing units and identifies when replacement is approaching. In Palm Beach, we focus on sealant integrity, hardware corrosion, and insulated glass unit (IGU) seal failure - the fogging between panes that indicates the desiccant is saturated. A maintenance visit includes frame readings, sightline measurements, and a photo record of conditions. We recommend annual inspection for ocean-facing homes and biennial for Intracoastal-facing properties. Maintenance visits run $180-$340.

AfterTrusted Brands We Service in Palm Beach
We draw from eight verified manufacturer lines, specified by what the opening requires, not by what is in stock. For Palm Beach’s salt-air environment and impact requirements, we regularly specify ECO Window Systems for energy-efficient vinyl, Mr-Glass for laminated impact glazing, and Therma-Tru for entry door systems. Custom historic profiles often come from ViewLux or ES Windows with PVF2-coated frames and stainless-steel hardware. We don’t carry inventory in a warehouse - we order to the measured survey, which eliminates the mismatch between what a contractor has on the truck and what your opening actually needs.
Common Window Replacement Problems We See in Palm Beach Homes
- Corroded steel casement frames in Mizner-era homes. Original 1920s-1940s steel windows in the Estate Section and Via Mizner area have reached end of service life. The frames pit, the hinges seize, and the glazing beads fail. Replacement requires custom impact-rated units that match ARCOM-mandated profiles.
- IGU seal failure showing as fogging between panes. Salt air accelerates seal degradation, particularly on south and west elevations. We see this frequently in 1980s-1990s replacement units that used standard sealant instead of marine-grade compounds.
- Non-impact windows that predate current Florida Building Code. Pre-2002 installations often lack Miami-Dade NOA or Florida Product Approval. These units won’t pass inspection for replacement permits and don’t qualify for wind-mitigation insurance credits.
- ARCOM rejection due to profile mismatch. Out-of-town contractors routinely underestimate the Town’s Architectural Commission requirements. We’ve been called in after permits were denied because mullion width, glass tint, or hardware finish didn’t match historic documentation.

FAQs - Window Replacement in Palm Beach
Replacement windows in Palm Beach must carry a Miami-Dade Notice of Acceptance (NOA) or Florida Product Approval, typically rated for 170 mph wind speeds or higher under the Florida Building Code. The exact pressure rating depends on the home’s exposure category - ocean-facing and Intracoastal-facing elevations on the barrier island face higher design pressures than inland locations. Our quotes include the specific NOA documentation for each product specified. Call (561) 475-1246 and we’ll show you the rating on the written estimate.
Yes, typically by four to eight weeks if not started before the permit application. The Town of Palm Beach’s Architectural Commission meets on a set schedule and requires exact matching of mullion profiles, glass tint, and hardware finishes against historic documentation before issuing a permit for landmarked properties. We handle ARCOM pre-submission as part of our scope, including the required drawings and product cut sheets. Contractors who skip this step see projects stall for months. Call (561) 475-1246 to discuss your property’s landmark status.
Yes, documented impact-rated windows typically qualify for wind-mitigation credits that reduce premiums 10-45 percent depending on your carrier and the full mitigation features of the home. The key is documentation: the Miami-Dade NOA, the passed inspection record, and the photo evidence we provide. We recently replaced original steel casements in a 1926 Addison Mizner home on Via Mizner in the Estate Section with custom ES Windows casements - laminated glass interlayer, PVF2-coated frames, ARCOM sign-off, Town inspection passed. The owners received their wind-mitigation credit. Call (561) 475-1246 to see how this applies to your policy.
Because Palm Beach sits on a barrier island less than half a mile wide, salt spray reaches both the ocean-facing and Intracoastal-facing elevations. Inland cities like West Palm Beach or Greenacres don’t experience this dual exposure. Standard aluminum or steel frames without marine-grade anodizing or PVF2 coating corrode rapidly, compromising the sealed IGU and voiding long-term performance. We specify marine-grade finishes and stainless-steel hardware as standard for Palm Beach, not as an upgrade. Call (561) 475-1246 for a frame assessment.
Usually no. Original 1920s-1940s steel frames in Palm Beach lack the structural depth and thermal break required for modern laminated impact glazing. The frames also typically show corrosion that compromises the sealant bed. Retrofit “impact film” or aftermarket glazing inserts don’t meet Florida Building Code for new installations and won’t pass inspection or qualify for insurance credits. We measure the existing opening and fabricate custom units that match the original sightline while meeting current code. Call (561) 475-1246 for a measured survey - estimates are free.
