Fast, Reliable Impact Windows & Doors Across Palm Beach
Impact window and door replacement in Palm Beach, FL typically runs $1,800-$4,500 per opening for custom-fabricated, ARCOM-approved units, with most projects requiring 8-14 weeks from measured survey to final installation due to historic commission review and custom IGU fabrication. Our Impact Windows & Doors team coordinates dispatch from our Miami office and serves Palm Beach properties directly, with crews experienced in the dual compliance burden that defines this barrier island.
We understand that a window replacement here is not a stock-unit swap. Palm Beach’s 1920s-1950s Mediterranean Revival and Bermuda Colonial estates, many designed by Addison Mizner or his followers, feature arched openings, loggia surrounds, and custom-dimensioned fenestration that standard manufactured units simply cannot fit. The salt-laden air from both the Atlantic and the Intracoastal Waterway attacks aluminum extrusions and fasteners from both sides simultaneously. And every exterior replacement must satisfy both the Florida Building Code’s coastal wind-load standards and the Town of Palm Beach Architectural Commission’s design review. We have completed this specific workflow hundreds of times since 2012. Call (561) 421-3844 to schedule your free measured survey - the written quote you receive is the price you pay, fixed before any order is placed.
Why Sightline Windows & Doors Boynton Beach Is Palm Beach’s Preferred Impact Windows & Doors Company
Our reputation in Palm Beach rests on documented completion of projects that other installers decline or mishandle. We have replaced impact-rated glazing in landmarked estates along South Ocean Boulevard, in Bermuda Colonial properties near El Bravo Way, and in Mediterranean Revival homes throughout the North End - each time navigating ARCOM or Landmarks Preservation Commission review without shortcuts.
Palm Beach customers have left verified reviews citing our crew’s preparedness: license numbers provided before arrival, background-checked and uniformed technicians, and the measured survey document they keep as a permanent record. The 365-Day Done Right Promise is stamped on every job, not offered as a courtesy - if the sightline measurement, glazing spec, or hardware finish is not what was written, we make it right.
Response time to Palm Beach is typically next-day for initial measured surveys, with scheduling coordinated from our Miami office. We do not promise same-day installation because that would be dishonest on custom-fabricated work; we do promise that your written quote cannot change once issued, and that your project timeline is communicated in full before you commit.
Local knowledge that matters: we know which Palm Beach properties fall under full LPC review versus ARCOM-only, we maintain relationships with the commission’s preferred profile fabricators, and we specify marine-grade hardware and stainless fasteners as standard - not as an upsell - because anything less fails prematurely in this salt environment.
Our Impact Windows & Doors Services in Palm Beach

Impact-Resistant Windows
Every impact-resistant window we specify for Palm Beach carries a design-pressure rating matched to its exposure - oceanfront parcels on South Ocean Boulevard regularly require DP-60 or higher, while Intracoastal-facing openings may qualify for slightly lower ratings depending on height and setback. We source from PGT, CGI, and ES Windows lines, specifying by performance tier rather than margin. The critical difference in Palm Beach is that the impact-rated unit must also pass ARCOM review for profile depth, finish color, and visible glazing characteristics. We submit all specifications for commission sign-off before fabricating custom IGUs, eliminating the risk of a finished product that meets code but fails design review.

Hurricane Impact Windows
Hurricane impact windows in Palm Beach must satisfy Florida Building Code coastal wind-zone requirements and, for HVHZ compliance, pass large-missile impact testing. But the Palm Beach-specific challenge is that many openings are arched, elliptical, or otherwise non-rectangular - common in Mizner-era estates along El Bravo Way and in the Estate Section. No manufacturer’s standard size chart accommodates these curves. Our crew measures the original frame geometry, fabricates laminated-glass impact IGUs to match, and specifies custom extrusions that replicate the historical profile depth. This is standard practice for us, not a special order. The result is a hurricane-rated window that also preserves the architectural character that defines Palm Beach property values.

Single Hung Impact Windows
Single hung impact windows - where the bottom sash operates and the top sash is fixed - are often specified for secondary elevations and service areas in Palm Beach homes. We see them frequently in staff quarters, garage apartments, and utilitarian wings of larger estates where the original fenestration was simpler. Even these utilitarian openings require ARCOM review if visible from the street, and we treat them with the same documentation rigor: measured survey, written quote, commission submission, custom fabrication, and photo record. For single hung units, we often specify CGI or CWS lines with coastal-grade hardware packages, as the salt air will seize standard operators within seasons.

Double Hung Impact Windows
Double hung impact windows, with both sashes operable, appear in Palm Beach’s later Colonial Revival and mid-century transitional homes, particularly in the North End and along Chilean Avenue. These units require precise balance systems to operate smoothly under the weight of laminated impact glass, and the hardware must be specified for coastal corrosion resistance. We have replaced failed double hung units in Palm Beach where inland-rated balances and zinc-coated fasteners were previously installed - a false economy that cost the homeowner a second replacement within five years. Our written spec for every Palm Beach double hung includes marine-grade stainless balances and fasteners, with the DP rating and U-factor documented on the quote you keep.

Wind Mitigation & HVHZ Code Compliance
Palm Beach sits within the High-Velocity Hurricane Zone, and wind mitigation documentation directly affects insurance premiums. We do not simply install impact windows; we provide the product approvals, installation certificates, and photographic evidence required for your wind mitigation inspection. Every opening receives a documented photo record showing the impact-rated label, the fastening pattern, and the surrounding weatherproofing - the evidence your inspector needs, included as standard under Haven Clause 4. If your property is on South Ocean Boulevard or another oceanfront exposure, we specify the highest available DP ratings and submit the documentation package with your final invoice.

AfterTrusted Brands We Service in Palm Beach
We specify from eight verified manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - matched to what each Palm Beach opening requires, not to inventory on hand. For historic ARCOM-reviewed projects, we frequently source PGT and CGI architectural series with custom color matching and extended profile depths that replicate Mizner-era millwork. For oceanfront exposures with maximum DP requirements, ES Windows and ViewLux lines offer the highest tested ratings. Therma-Tru entry systems integrate with impact-rated sidelights and transoms for complete door assemblies. We do not stock “standard” units in a warehouse; every order is fabricated to the measured survey we complete at your property, with lead times communicated in writing before you commit.
Common Impact Windows & Doors Problems We See in Palm Beach Homes

- ARCOM or LPC approval skipped or filed too late. A contractor orders impact-rated units that meet Florida Building Code, but the profile depth, finish color, or visible glazing fails Architectural Commission review - even if the impact rating is correct. The result is a rejected installation and a restart of the fabrication cycle. We submit for sign-off before ordering, every time.
- Standard manufactured units ordered for arched or custom-dimensioned openings. A Mizner-era elliptical window on El Bravo Way or a loggia surround in the Estate Section cannot accept any unit from a manufacturer’s size chart. The stock unit arrives, does not fit, and expensive re-fabrication blows both schedule and budget. We measure custom and fabricate to fit - the only approach that works here.
- Salt corrosion from dual exposure. Palm Beach’s position on a narrow barrier island means salt-laden air from the Atlantic and the Intracoastal attacks frames and hardware from both sides. Inland-rated aluminum extrusions and non-marine fasteners corrode prematurely. We specify coastal-grade materials as standard, documented on your written quote.
- Generic hardware substituted for HVHZ-rated components. A contractor installs impact-rated glazing but uses standard hinges, operators, or fasteners not rated for the design pressure or salt environment. The window meets code on paper but fails in service. Our written spec names every component by manufacturer and rating; the photo record verifies installation.
Pricing for Impact Windows & Doors in Palm Beach, FL
Impact window and door replacement in Palm Beach carries a premium over inland markets, driven by custom fabrication, dual commission review, and marine-grade material specifications - not by labor markup. Here is what we typically see in written quotes across our Palm Beach projects:
| Opening Type | Typical Range in Palm Beach |
|---|---|
| Standard rectangular impact window (ARCOM-approved, custom-fabricated) | $1,800 - $3,200 |

FAQs - Impact Windows & Doors in Palm Beach

Yes. Every exterior window or door replacement in the Town of Palm Beach requires Architectural Commission review for profile depth, finish color, and visible glazing characteristics, regardless of whether the unit exceeds Florida Building Code impact and wind-load requirements. Landmark-designated properties face an additional Landmarks Preservation Commission review layer. We submit all specifications for commission sign-off before fabricating or ordering any custom unit. Call (561) 421-3844 and we will walk you through the specific review path your property requires.
Most Palm Beach homes built during the 1920s-1950s feature arched, elliptical, or custom-dimensioned openings from the Mizner-era Mediterranean Revival and Bermuda Colonial periods - fenestration that no manufacturer’s standard size chart accommodates. On an El Bravo Way estate with arched Mizner-era openings, off-the-chart elliptical frames meant no stock unit would fit - our crew custom-fabricated laminated-glass impact IGUs to the original curves, matched the historical profile depth, and used stainless fasteners and marine-grade hardware to survive salt air from both the Atlantic and the Intracoastal. We submitted the profile and finish color to ARCOM for sign-off before ordering, and the ES Windows units were installed with design-pressure ratings matched to the oceanfront exposure. The custom fabrication and approval cycle added about seven weeks to a schedule that would have been days inland. Your measured survey will document exactly what fabrication your openings require.
Palm Beach’s position flanked by the Atlantic Ocean and the Intracoastal Waterway exposes window frames and door hardware to salt-laden air from both sides simultaneously, accelerating corrosion of aluminum extrusions and stainless fasteners far faster than even nearby inland communities. We specify marine-grade hardware, coastal-rated balances, and stainless or epoxy-coated fasteners as standard on every Palm Beach job - documented on your written quote, verified in the photo record. Generic inland-rated components fail prematurely here; we do not install them. Call (561) 421-3844 for a written spec that names every material by grade and manufacturer.
Impact-rated windows on all glazed openings, properly installed with HVHZ-compliant fastening and documented with product approvals, typically qualify for significant wind mitigation insurance credits in Palm Beach. However, the key is documentation: the inspector needs to see impact-rated labels, proper fastening patterns, and weatherproofing details. We provide a complete photo record and installation certificate with every job - evidence included as standard, not as an upsell. The 365-Day Done Right Promise covers any documentation gap we miss. Call (561) 421-3844 to discuss your specific opening count and exposure.
Low-E impact glass with appropriate SHGC (Solar Heat Gain Coefficient) ratings can reduce cooling load substantially in Palm Beach’s intense solar exposure, particularly on west- and south-facing elevations. The laminated impact interlayer adds insulation value beyond standard glazing, and the Low-E coating rejects infrared heat while preserving visible light. We specify U-factor and SHGC on every written quote, matched to your elevation exposure and any shading from mature banyans or other landscape features common in Palm Beach estates. The savings are real but vary by home; we do not promise a specific dollar reduction without evaluating your specific fenestration area and orientation. Call (561) 421-3844 for a measured survey that includes solar load analysis.
