Fast, Reliable Custom & Geometric Windows Across Palm Beach
Custom and geometric window work in Palm Beach runs on a different timetable than anywhere else in South Florida. A standard impact window replacement can move in days. An arched casement on a Mizner-era estate on the island can take six to eight weeks just to clear the Architectural Review Board before a single screw gets turned. We know that calendar because we’ve lived it for over 15 years, and we build every Palm Beach job around it from the first phone call. If you’re pricing an arched, radius, or custom-shaped opening in Palm Beach, call (561) 468-6136 and we’ll walk you through the real process, not a sales pitch.

Key Takeaways:
- Most custom and geometric impact windows in Palm Beach run $2,500 to $5,000 per opening, installed, depending on size and profile.
- Historic structures under ARBA review need a 6 to 8 week approval window before installation can begin.
- Marine-grade finishes and stainless fasteners are not optional on a barrier island with salt air from both the Atlantic and the Intracoastal.
- We file the ARBA submittal for you, matching original radius and muntin profiles in modern impact-rated product from PGT and CGI.
- Call (561) 468-6136 for a free in-home measure and written, line-item quote.
Why Winslow Windows & Doors Is Palm Beach’s Preferred Custom & Geometric Windows Company
Ed Winslow’s name is on the door, and on every job we do in Palm Beach. That means when an ARBA submittal needs a revision, or a custom radius comes back from fabrication a quarter inch off, there’s no ticket number and no call center. Ed is the one who answers. The company has been locally owned and owner-operated since 2011, with a published address and license number, and we installed our share of Impact Windows in Palm Beach on the island long before most of our competitors learned what ARBA stands for.
We’re an authorized installer for PGT, CGI, CWS, and ES Windows, which matters in Palm Beach because the town’s review process is unforgiving about profile fidelity. A standard square impact window dropped into a 1930s arched opening gets red-tagged. We’ve seen it happen to homeowners who hired a big-box installer that bid the job from a catalog. Our team measures every radius, every muntin bar, every transom curve before we file anything with the board. That’s why Palm Beach homeowners call us when the opening isn’t a rectangle.
Every technician who arrives at a Palm Beach property is background-checked and in uniform. You know who’s at your gate before the truck pulls through. And when you call at 2 a.m. with a shattered pane on an oceanfront estate, a live person picks up. No voicemail loop, no next-business-day callback. Call (561) 468-6136 and you’ll talk to a human being.
Our Custom & Geometric Windows Services in Palm Beach
Custom Impact Windows
On Palm Beach’s barrier island, code-rated impact protection is not a suggestion. But for homes built between 1920 and 1950, the architectural charm that defines the town’s character sits in arched openings, decorative transoms, and wrought-iron details that standard impact product lines cannot fit. We spec custom impact windows from PGT and CGI with design pressures matched to each opening, and we handle the Florida Product Approval documentation the board requires. Marine-grade finishes are standard on every ocean-side installation.

Geometric & Shaped Windows
Triangle, trapezoid, pentagon, octagon, half-round, quarter-round. We’ve fabricated and installed every geometry Palm Beach’s historic and contemporary estates can throw at us. The challenge on the island is rarely the glass itself. It’s proving to the ARBA that the modern impact-rated unit replicates the original profile closely enough to pass review. We build that proof into the submittal package from day one. For homeowners across the Intracoastal in West Palm Beach or up in Palm Beach Gardens, the process is simpler, but we bring the same fabrication discipline to every opening, whether custom windows or Shingle, Tile & Metal Roofing - Palm Beach projects.

Arched & Curved Windows
This is the work that defines custom window installation on Palm Beach. On a Mizner-era Mediterranean Revival estate in the Estate Section, our crew replaced a failing original arched casement overlooking the Intracoastal with a custom PGT impact-rated casement matching the original radius and muntin pattern. We filed the ARBA submittal in early March before the owner left for the season, and when approval came through in May, our install moved straight from permit to finished trim with no gap. That’s how the calendar is supposed to work. Most contractors on the island learn this the hard way. We already have.

Oversized Openings
Palm Beach’s grand estates were built for scale, and that means openings that span eight, ten, sometimes twelve feet. Oversized custom windows in a mid-century CBS home on the interior streets fall under the same ARBA scrutiny as a Mizner mansion on South Ocean Boulevard. We engineer each large-format opening for the wind loads Palm Beach’s HVHZ zone demands, match the aesthetic profile the board will approve, and coordinate fabrication so the install doesn’t sit half-finished waiting on a committee. Call (561) 468-6136 for a free measure and written quote on any oversized opening.

Trusted Brands We Service in Palm Beach
We are an authorized installer for PGT, CGI, CWS, and ES Windows, and we spec each brand where it fits best. PGT’s custom impact line handles more of our arched and radius work on the island than any other brand because the factory can match complex muntin patterns and custom radii without sacrificing wind-load ratings. CGI carries weight on oceanfront estates where salt exposure is brutal and frame integrity matters over decades. We maintain direct factory relationships, which means faster turnaround on custom lites for Palm Beach customers than a reseller who’s ordering through a distributor. You can learn more about our Custom & Geometric Windows team’s capabilities, or keep reading for how the island’s review process actually works.
Common Custom & Geometric Windows Problems We See in Palm Beach Homes
- ARBA rejections for profile mismatch. A homeowner bids a standard impact window for an arched opening, the submittal goes in, and the board denies it because the radius or muntin pattern doesn’t match the original. Now the seasonal owner is back north, the calendar is blown, and the install lands in August. We file the submittal with fabrication drawings that prove fidelity before the board ever sees it.
- Salt-laden air eating untreated aluminum. Palm Beach sits on a narrow barrier island with the Atlantic on the east and the Lake Worth Lagoon on the west. Every structure gets salt exposure from both sides simultaneously. Untreated aluminum frames pit within a few years and hardware seizes. We spec marine-grade finishes and stainless fasteners on every installation within a block of the water, no upsell required.
- Seasonal owners losing the project to the calendar. ARBA review on a historic structure runs six to eight weeks. If you’re only in Palm Beach from October through April and you start the review in November, your install lands in January at best, and more likely after you’ve left again. We start the submittal in the spring, before owners head north, so the permit is ready when the window opens.
- Structural fatigue in original steel casements. Those beautiful original steel windows on a 1930s Spanish Colonial were never designed for hurricane wind loads. Over decades, the frames rust from salt air, the putty fails, and the glass rattles in its setting. Retrofitting a modern impact-rated window into that opening means matching the original sightlines while upgrading the structural frame. That’s the work we do most on the island.
Pricing for Custom & Geometric Windows in Palm Beach, FL
Custom impact window pricing in Palm Beach is not a mystery, but it is specific. A standard impact window in a rectangular opening on a mid-century CBS home on the interior streets might run $900 to $1,800 installed. Once the opening is arched, radiused, or geometric, you’re into custom fabrication territory, and Palm Beach’s market reflects it. Expect $2,500 to $5,000 per custom opening, installed, with higher ceilings for oversized oceanfront openings that require engineering and crane work. Whole-home packages on a historic estate can land between $8,000 and $25,000 or more depending on opening count, floor height, and frame material. We give you a written, line-item quote before any work starts, and the price doesn’t change mid-job. Call (561) 468-6136 to schedule a free in-home measure.
What Custom & Geometric Windows Costs in Palm Beach
Here’s a straight answer for Palm Beach’s market. Impact windows generally run $800 to $1,500 per window installed for standard rectangular openings. Impact single-hung units run $900 to $1,800. Large or custom openings, which is most of what Palm Beach’s historic stock demands, run $2,500 to $5,000 per opening. Whole-home packages on estate properties run $8,000 to $25,000 and up. What moves the price in Palm Beach specifically: the number of openings the ARBA will review as one submittal, the wind zone and floor height (a third-story arched casement on South Ocean Boulevard needs a higher design pressure than a first-floor unit in a CBS home on the interior streets), and the frame material, with marine-grade aluminum and stainless hardware adding cost against standard aluminum. The close is simple: call (561) 468-6136 and we’ll measure, spec, and quote in writing, free of charge.
One comparison worth making before you decide: impact windows versus hurricane shutters. Shutters get you code compliance but you’re still hanging panels in the wind every time a storm tracks toward Palm Beach, and they do nothing for the salt-air corrosion eating your current frames. Impact windows are permanent protection, they’re in place the moment the storm is named, and they raise the property’s resale value in a town where buyers expect the protection built in. And unlike a big-box retail install, a licensed impact specialist matches the profile the ARBA will approve and the documentation the board will require.

Florida Pays You Back
The incentives for impact-rated custom windows are real, and Palm Beach homeowners should stack every one of them. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, pending funding availability and inspection. Florida exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit covers 30% of product cost, up to $600 per year, on qualifying energy-efficient units. And most windstorm carriers drop the windstorm premium by roughly 25% after a wind-mitigation inspection confirms the rated openings; the inspection itself runs $75 to $150. We can’t guarantee what your carrier approves or what the state legislature funds, but we can tell you which of our products meet the certification thresholds. Call (561) 468-6136 and we’ll help you sort out what applies to your property.
On ratings: every Palm Beach installation we sell carries a Miami-Dade NOA or Florida Product Approval number per configuration, HVHZ compliance where the opening’s wind zone requires it, and design pressures matched to the specific opening. We never spec a rating above +/-100 for an opening that doesn’t need it, and we never install a window that’s under-rated for its location.
The Palm Beach ARBA Compliance Playbook
Here’s what no national installer will tell you about Custom & Geometric Windows in Palm Beach. The town’s Architectural Review Board has jurisdiction over virtually every exterior change on the island. Window and door replacements on the Mediterranean Revival estates that dominate the Estate Section, Everglades Island, and the streets along South Ocean Boulevard, most of them built during Addison Mizner’s 1920s boom, must receive board approval and replicate the original arched, multi-lite, or steel-casement profiles in a modern impact-rated product. This is not a suggestion. It’s the reason a lot of standard impact-window bids for Palm Beach homes never become installations.
Because so many Palm Beach property owners are seasonal residents present only from roughly October through April, the ARBA review cycle, which runs six to eight weeks for historic structures, must be started the prior spring before owners leave. Contractors who don’t build that lead time into their sales process routinely lose jobs to the calendar, not the competition. We’ve filed enough submittals to know exactly what the board wants to see: fabrication drawings showing the original profile and the proposed match, finish samples, sightline details, and structural engineering for any opening that changes load paths. We file the packet. We answer the board’s questions. And we schedule fabrication so your windows arrive when the permit clears, not six weeks before it.
That’s the playbook: get the submittal in early, match the profile exactly, and never let a job sit half-finished waiting on a committee. Call (561) 468-6136 and we’ll start the paperwork now, before the calendar becomes the enemy.

FAQs - Custom & Geometric Windows in Palm Beach
Yes. The Architectural Review Board requires a submittal packet that includes fabrication drawings showing the original arched profile with the proposed impact-rated match, finish samples, sightline details for muntins and mullions, and structural engineering for any opening that changes load paths, plus the Florida Product Approval documentation. We assemble and file the entire packet for you. Call (561) 468-6136 and we’ll start yours this week.
No, not on the island. The ARBA will reject any submittal that alters the original arched profile, which means a standard square impact window cannot be substituted into an arched opening on a historic or non-historic structure under the board’s jurisdiction without approval. You need a custom radiused or arched impact unit that matches the original geometry. That’s the work we do every season. Call (561) 468-6136 for an exact quote, estimates are free.
Marine-grade aluminum frames with a protective finish, stainless steel fasteners on all hardware, and corrosion-resistant components throughout the window assembly, not just the visible frame. Palm Beach’s barrier-island exposure means salt air from the Atlantic and the Intracoastal attacks every metal surface simultaneously. Untreated aluminum will pit within a few years. We spec these upgrades as standard on ocean-side installations. Call (561) 468-6136 to discuss your specific opening.
Yes, impact-rated custom geometric windows qualify for the same windstorm premium reductions as standard impact windows, provided they carry a valid Miami-Dade NOA or Florida Product Approval and the installation passes a wind-mitigation inspection, which typically runs $75 to $150. Most carriers average around a 25% reduction on the windstorm portion after verification. Call (561) 468-6136 and we’ll tell you which of our products hit the certification thresholds.
Because the ARBA review cycle on a historic Palm Beach structure runs six to eight weeks, and if you wait until you’re back in October to file, the installation lands in December at best, and more likely after the holidays, when the hurricane season has already begun again. We file the submittal in the spring before owners leave, so the permit clears while you’re north and the install happens the week you return. That’s the only way the calendar works on the island. Call (561) 468-6136 now and we’ll get your submittal in the queue before you leave.
