Fast, Reliable Window Replacement Across Palm Beach
Window replacement in Palm Beach runs $890-$4,200 per opening depending on frame material, glazing specification, and whether the job requires custom fabrication for arched or historic profiles. Most full-frame replacements on the island take two to four weeks once ARCOM or Landmarks Preservation Commission approval is secured, though custom curved impact units can extend that to ten weeks. Call (561) 421-3844 to schedule a measured survey - the written quote you receive is the same document that governs the installation.
We serve Palm Beach from our Miami-area dispatch office, with crews crossing the Flagler Memorial Bridge or Royal Park Bridge daily to measure, install, and service openings from Sloan’s Curve to the north end near the Palm Beach Inlet. The barrier island’s conditions are not theoretical to us. We have documented photo records of corroded aluminum jambs on El Bravo Way, failed gaskets on South Ocean Boulevard, and steel casement frames pitted through by salt aerosol on both the ocean and Intracoastal sides of the same property. That field history shapes what we specify for your job.
Why Sightline Windows & Doors Boynton Beach Is Palm Beach’s Preferred Window Replacement Company
Our Window Replacement team has completed installations across Palm Beach’s distinct neighborhoods, from the landmark estates near Worth Avenue to the Bermuda Colonial homes lining Chilean Avenue and the oceanfront properties along South Ocean Boulevard. We understand that a window replacement here is not a commodity purchase. It is a compliance exercise that must satisfy the Town of Palm Beach’s Architectural Commission, the Florida Building Code’s coastal wind-zone requirements, and the physical reality of salt-laden air attacking every exposed surface.
We do not quote from a truck. Every engagement begins with a measured survey you keep, and the written price before any work starts cannot differ from that document - Haven Clause 1 since 2012. Our technicians are background-checked, uniformed, and identified by license number before arrival. Every completed job carries the 365-Day Done Right Promise and leaves a documented photo record, not as a courtesy but as standard evidence under the Haven Standard.

Our Window Replacement Services in Palm Beach

Full Frame Replacement
Full frame replacement in Palm Beach removes the entire existing window, including the jamb, sill, and exterior trim, down to the rough opening. This is the required approach when original steel casement frames have corroded through, when the existing frame is out of square beyond shim tolerance, or when upgrading from non-impact to impact-rated glazing. On Palm Beach’s barrier island, we specify marine-grade anodized or Kynar-coated aluminum extrusions with Type 316 stainless fasteners even on west-facing elevations - the salt aerosol reaches from both the Atlantic and the Intracoastal, and mill-finish aluminum corrodes at cut edges within a few years. The price gap between coastal-spec and inland-spec full frame replacement typically runs 18-25 percent, but the alternative is a second replacement within a decade.

Insert Window Replacement
Insert replacement, sometimes called pocket replacement, installs a new window unit inside the existing frame. This works when the original frame is structurally sound, square, and free of corrosion. In Palm Beach, we rarely recommend inserts for oceanfront properties or homes within two blocks of either shore - the salt load that attacks the frame exterior will eventually compromise the jamb interior too, and an insert masks that decay until it becomes an emergency. For inland Palm Beach locations or well-maintained Bermuda Colonial homes on Chilean Avenue with intact original wood frames, inserts can be appropriate. We measure the existing frame with a moisture meter and document the reading; if the jamb shows elevated moisture or salt crystallization, we recommend full frame instead.

Vinyl Replacement Windows
Vinyl frames are not our primary specification for Palm Beach coastal applications. The material itself is dimensionally stable and thermally efficient, but standard vinyl formulations can degrade under intense UV and salt exposure, and the expansion-contraction cycle in Florida’s heat can stress corner welds. Where vinyl is appropriate - typically for secondary elevations on inland Palm Beach properties or for budget-conscious insert replacements - we specify cellular PVC or reinforced composite frames from manufacturers like CWS or ECO Window Systems, with coastal-rated hardware. We do not install off-the-shelf vinyl units on oceanfront or Intracoastal-facing openings without explicit owner acknowledgment of reduced service life.

Energy-Efficient Upgrade
Energy-efficient window replacement in Palm Beach must balance solar heat gain control against hurricane impact requirements. We specify low-E coatings with a low SHGC (Solar Heat Gain Coefficient) to reduce cooling load, paired with laminated impact glass that meets Palm Beach County’s design pressure ratings. The U-factor measures heat transfer; for Palm Beach’s climate, we target 0.30 or lower. Our crew replaced the arched loggia surrounds on a 1926 Mediterranean Revival estate along South Ocean Boulevard where the original steel casement frames had pitted through and the impact IGUs could not accept any stock unit - we custom-fabricated curved, laminated-glass impact units with a low-E coating and a stainless jamb anchor system, then secured ARCOM approval on the profile depth and finish before the sashes ever left the shop. The job took eight weeks longer than a comparable West Palm Beach replacement, but the new frame should outlast the original steel by decades against that oceanfront salt load.

Window Maintenance & Care
Maintenance in Palm Beach is preventive, not cosmetic. We inspect glazing gasket condition, weep hole function, and frame seal integrity; replace degraded perimeter seals before they fog the IGU; and document corrosion progression on hardware and fasteners. Annual maintenance extends unit life by years on the barrier island.

AfterTrusted Brands We Service in Palm Beach
We draw from eight verified manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - specified by what the opening requires, not by what is in stock. For Palm Beach’s historic and coastal applications, we most frequently specify PGT and CGI for impact-rated aluminum systems with marine-grade finishes, and ES Windows for custom-fabricated curved or geometric units that must clear ARCOM review. We do not ask you to choose from a catalog and hope it fits. We measure, we specify, we document, and we install.
Common Window Replacement Problems We See in Palm Beach Homes

- Corroded aluminum jambs on oceanfront and El Bravo Way estates. The salt-laden air from both the Atlantic and Intracoastal attacks unprotected mill-finish metal at cut edges and anchor points. We specify marine-grade anodized or Kynar-coated frames instead, with Type 316 stainless fasteners.
- Failed glazing gaskets and IGU perimeter seals from salt and UV degradation. Ordinary gasket compounds harden and crack within three to five years on the barrier island, fogging the insulated glass unit and voiding wind mitigation credit. We use low-E laminated glass with a stainless spacer and a gasket compound rated for coastal exposure.
- Standard impact units forced into 1920s arched or elliptical openings. Contractors who install stock rectangular units in Mizner-designed curves create fitted voids that trap water and defeat the design pressure rating. We custom-fabricate impact IGUs to the actual curve and seal the jamb perimeter with marine-rated sealant.
- ARCOM rejection of incompatible profiles or finishes. The Town of Palm Beach’s Architectural Commission requires period-correct proportions matching original Mediterranean Revival or Bermuda Colonial architecture. We submit profile drawings and finish samples for approval before fabrication begins, avoiding the cost and delay of a rejected installation.
Pricing for Window Replacement in Palm Beach, FL
These ranges reflect coastal-spec materials and ARCOM-compliant installation for the Palm Beach market in 2025. Inland-spec pricing, where appropriate, is noted for comparison.

FAQs - Window Replacement in Palm Beach

You cannot, because the arched and elliptical openings in Mizner-era Mediterranean Revival and Bermuda Colonial estates were built before standardized window manufacturing existed. Standard rectangular units leave fitted voids that trap water and fail the design pressure test. We custom-fabricate curved impact IGUs to the measured radius of your opening, then seek ARCOM sign-off on profile depth and finish before the sashes leave the shop. Call (561) 421-3844 to schedule a measured survey of your openings - estimates are free.
Yes, if your property is within the Town of Palm Beach. The Architectural Commission requires design approval for any exterior window or door replacement, and designated landmark properties face an additional Landmarks Preservation Commission review layer. This dual compliance burden does not apply across the Intracoastal in West Palm Beach or Lake Worth. We prepare and submit all required drawings, finish samples, and product specifications as part of our scope. Call (561) 421-3844 to confirm whether your address falls under ARCOM jurisdiction.
Marine-grade anodized aluminum with a Kynar finish, paired with Type 316 stainless fasteners, outperforms standard mill-finish aluminum by decades on the barrier island. The salt aerosol from both the Atlantic and the Intracoastal attacks unprotected metal at cut edges and anchor points; we have documented corrosion failure within three to five years on oceanfront and El Bravo Way properties that used inland-grade specifications. Vinyl and standard aluminum are not recommended for primary elevations within two blocks of either shore. Call (561) 421-3844 to discuss material specification for your specific exposure.
Yes, typically through wind mitigation credits. Florida insurers discount premiums for documented impact-rated glazing that meets or exceeds the Florida Building Code’s design pressure requirements for your wind zone. Palm Beach’s coastal location places most properties in the highest DP rating category. We provide the product approval documentation, installation certificate, and photo record required for your wind mitigation inspection. The exact discount depends on your carrier and the full mitigation features of your home. Call (561) 421-3844 and we will review what documentation your policy requires.
The material specification differs at every component: marine-grade anodized or Kynar-coated frames instead of mill-finish aluminum; Type 316 stainless fasteners instead of standard zinc-plated; coastal-rated gasket compounds instead of standard EPDM; and often custom fabrication instead of stock units. On Palm Beach’s barrier island, salt aerosol reaches window frames from both the Atlantic and the Intracoastal, so we specify the coastal grade even on west-facing elevations - a specification that would be overkill on a West Palm Beach job one mile inland and typically saves owners from full-frame replacement within a decade. The upfront cost gap is 18-25 percent. The avoided replacement cost is 100 percent. Call (561) 421-3844 for a written quote on either specification.
Call (561) 421-3844 to schedule your free measured survey. You will receive a written, line-itemed price before any work starts, and that document will govern the installation. Every job carries the 365-Day Done Right Promise and leaves a documented photo record. Haven Clause 1. Haven Clause 3. Haven Clause 5. No surprises.
