Fast, Reliable Window Replacement Across Palm Beach
Window replacement in Palm Beach, FL typically runs $1,800-$4,500 per opening for full-frame impact-rated units in historic homes, with most measured surveys scheduled within 48 hours and installation following ARCOM approval. Because Palm Beach sits on a narrow barrier island with salt air from both the Atlantic and the Intracoastal, standard hardware corrodes fast here - marine-grade stainless or bronze isn’t optional, it’s required for any unit to last. Our crews serve Palm Beach from our South Florida coordination office, and we’ve handled everything from South Ocean Boulevard estates to condominium stacks near Worth Avenue. Call (561) 461-2062 to schedule your free measured survey.

Our Window Replacement Services in Palm Beach

Full Frame Replacement
Full frame replacement in Palm Beach means removing the entire existing window, frame, and trim down to the rough opening - and on this island, that opening is often 12-inch CBS with custom masonry arches laid out in the 1920s or 1930s. On South Ocean Boulevard, our crew opened a 1920s Mizner-era Mediterranean Revival wall and found 12-inch CBS with no standard rough-opening dimension - the original arch was laid out in custom masonry, so we custom-fabricated a PGT impact-rated casement with a bronze frame to match the profile rather than modifying the opening, which ARCOM would have rejected. While the wall was open we discovered outdated knob-and-tube wiring and undersized header framing; we documented both, priced them in writing, and got owner approval before proceeding, then upgraded waterproofing and met current HVHZ design pressure and wind mitigation code triggered by the permit. This is why we inspect first, write allowances into every contract, and price any surprise in writing before touching it.

Insert Window Replacement
Insert replacement fits a new window into the existing frame, which sounds simpler until you realize most Palm Beach frames from the Mizner era are steel or deteriorated wood set in thick stucco. We measure the actual sightline - the visible glass area - and check whether the existing frame can carry an impact-rated unit’s weight and anchoring requirements. When the frame won’t support it, we tell you before quoting, not after starting. No insert replacement in Palm Beach proceeds without confirming the existing frame meets HVHZ anchorage standards.

Vinyl Replacement Windows
Vinyl performs well in Palm Beach when specified correctly, which means titanium dioxide in the capstock for UV resistance and multi-chambered frames that don’t warp in the island’s heat. We specify vinyl from ECO Window Systems and ViewLux by performance tier and price range, not by margin. For oceanfront or Intracoastal-facing elevations, we typically steer customers toward reinforced vinyl or aluminum-clad options with marine-grade hardware - standard operators and weep holes corrode within two to three years in Palm Beach’s double salt-spray corridor.

Energy-Efficient Upgrade
Palm Beach’s cooling load is extreme, and old single-pane or failed insulated glass units bleed money eight months a year. We specify energy-efficient upgrades using U-factor and SHGC ratings appropriate for South Florida’s climate - low U-factor for heat transfer resistance, low SHGC to block solar gain. Our energy-efficient upgrades draw from ES Windows and ECO Window Systems lines with NFRC-certified performance data, and we explain the numbers in plain English on the written quote. Many Palm Beach customers see measurable utility reductions, though we quote the performance specs, not the savings.

Window Maintenance & Care
Maintenance in Palm Beach isn’t cleaning - it’s corrosion inspection, weep-hole clearing, and hardware lubrication with marine-grade compounds. We offer maintenance visits that include a documented photo record of frame condition, hardware operation, and seal integrity. Catching corrosion early on a South Ocean Boulevard casement means replacing an operator, not fabricating a custom arched unit because the frame seized and cracked the glass. For landmark properties, maintenance records also support ARCOM compliance documentation.

AfterTrusted Brands We Service in Palm Beach
We install and service eight manufacturer lines in Palm Beach, specifying by what the opening requires, not by what is in stock. For the island’s historic Mediterranean Revival facades, we regularly source custom-fabricated impact units from PGT and CGI in bronze profiles that ARCOM will approve. ES Windows and ECO Window Systems supply our energy-efficient and vinyl tiers. For customers near the Breakers or along Chilean Avenue seeking specific aesthetic matches, Mr-Glass and Therma-Tru offer profile options we can verify against existing masonry before ordering. We do not stock inventory in a warehouse and hope it fits - we measure, specify, and order to the opening.
Common Window Replacement Problems We See in Palm Beach Homes

- ARCOM rejection for non-compliant profiles. The Architectural Commission rejects permits when proposed replacements don’t maintain the historic Mediterranean Revival character - wrong profile, wrong color, or a catalog unit that doesn’t match the 100-year-old arched masonry opening. We submit manufacturer cut sheets and finish samples with every Palm Beach permit package.
- Marine-grade hardware omitted from specification. Standard hardware, frames, and weep holes that perform fine in inland South Florida communities corrode within two to three years in Palm Beach without marine-grade stainless, bronze, or properly coated aluminum. We specify the grade in writing on every quote.
- Hidden conditions in 12-inch CBS walls. Opening a Mizner-era wall routinely reveals outdated wiring, undersized or damaged framing, or failed waterproofing. Our contracts include written allowances for these conditions, and any surprise is priced and approved in writing before we proceed.
- Design pressure miscalculations for HVHZ. Palm Beach sits in Florida’s highest-wind coastal zone. Every replacement must meet current HVHZ design pressure requirements triggered by the permit, which often exceeds what the original unit was built to withstand. We engineer every opening to current code, documented in the permit package.

Energy-efficient upgrades with low-E coatings and argon fill add $150-$400 per unit depending on size and performance tier.

FAQs - Window Replacement in Palm Beach

Yes, any exterior window or door replacement in the Town of Palm Beach requires Architectural Commission (ARCOM) approval before a building permit can issue. ARCOM reviews for compliance with the historic Mediterranean Revival character that defines the island, including profile, color, and proportion. We prepare and submit the manufacturer cut sheets, finish samples, and photographic documentation as part of our standard service. Call (561) 461-2062 to schedule your free measured survey.
Because the original openings were laid out in custom masonry arches with no standard rough-opening dimension, and ARCOM will not approve altering the arch profile. On South Ocean Boulevard and the estate streets behind it, we routinely custom-fabricate impact-rated units to fit the existing opening rather than modifying the 12-inch CBS wall. The product must match the architecture; the architecture does not adapt to the product. Call (561) 461-2062 for an exact quote - estimates are free.
Opening a wall triggers current High-Velocity Hurricane Zone (HVHZ) design pressure and wind mitigation requirements, plus any needed structural, electrical, or waterproofing upgrades to meet code. We inspect before quoting, include written allowances in the contract, and document any surprise conditions with photos and a written price before proceeding. Nothing is started without your approval in writing. Call (561) 461-2062 to schedule your free measured survey.
Standard hardware, frames, and weep holes corrode and seize within two to three years in Palm Beach’s double salt-spray exposure - Atlantic on the east, Intracoastal on the west - a dual-direction problem absent even in neighboring coastal towns like West Palm Beach or Boca Raton. We specify marine-grade stainless or bronze hardware in writing on every Palm Beach quote. Call (561) 461-2062 for an exact quote - estimates are free.
Impact-rated windows and doors that meet Florida Product Approval and HVHZ standards typically qualify for wind mitigation credits with most insurers, though the exact discount varies by carrier and policy. We document every installation with product approval numbers, permit sign-off, and photo evidence to support your wind mitigation inspection. We do not quote specific savings; we deliver the documentation your inspector needs. Call (561) 461-2062 to schedule your free measured survey.
