Fast, Reliable Custom & Geometric Windows Across Palm Beach
Custom and geometric window replacement in Palm Beach runs $2,500 to $5,000 per opening for true custom impact-rated units, and the single biggest wildcard is what’s hiding behind the old frame. On a barrier island where ARCOM reviews nearly every visible window change and salt air corrodes original steel casements from two directions, a straightforward swap can become a framing-and-flashing job the moment we open the wall. That’s why we quote Palm Beach projects differently: inspection first, allowances written into the contract, and every surprise approved in writing before we touch it. If you’re planning to replace an arched, curved, or odd-shaped window, call (561) 782-7525 for a free in-home measure and a written quote that actually holds up.
Why Winslow Windows & Doors Is Palm Beach’s Preferred Custom & Geometric Windows Company
Ed Winslow founded this company in 2011, and his name is on the door and on every job we do. We’re not a national chain with a rotating cast of subcontractors; we’re the locally owned crew Palm Beach homeowners call when an arched Mizner-era casement needs to match a 90-year-old profile and still hold an HVHZ wind rating.
Palm Beach customers know what the permitting process costs in time and frustration. The Town’s Architectural Commission meets on a set monthly schedule, and missing the submittal deadline can push a project three to four weeks before you can even pull a permit. We build that reality into every estimate we write on the island, so your timeline doesn’t quietly shift under you. Our Palm Beach reviews consistently mention two things: we show up when we say we will, and the final invoice matches the quote. Every call is answered by a live person, 24/7, and every technician who arrives at your door is background-checked and in uniform. You’ll know exactly who’s walking up your driveway before the truck stops.
Our Custom & Geometric Windows Services in Palm Beach
We build and install shaped windows that most window companies won’t quote. On a barrier island where the Town of Palm Beach’s Architectural Commission enforces historic profile matching on Addison Mizner-era estates, “custom” isn’t a luxury designation. It’s a permitting requirement. Our Custom & Geometric Windows team handles the full range, from single-unit replacements to whole-facade re-glazing on South Ocean Boulevard estates.
Custom Impact Windows
Every custom impact window we supply for Palm Beach carries Miami-Dade NOA and Florida Product Approval documentation matched to your specific opening and wind zone. Because Palm Beach sits fully exposed to Atlantic hurricane tracks with no inland buffer, we default to PGT and CGI units engineered for large-missile impact rather than the lighter ratings some mainland contractors quote. You get the same laminated glass interlayer performance from a window that looks like it’s been there for 80 years.

Geometric & Shaped Windows
Triangles, octagons, trapezoids, pentagons, rake-heads. Palm Beach’s Mediterranean Revival homes use geometric windows as focal points on stairwells, gables, and entry facades, and each one needs a frame profile that matches its neighbors. We order every unit from manufacturers who cut to decimal-inch tolerances, then field-verify the rough opening before the glass goes into production. No close-enough substitutions.

Arched & Curved Windows
The arched window is the defining feature of Mizner-era Palm Beach architecture, and it’s also the most difficult to replace correctly. True radius windows require either segment-top or curved-frame construction matched to the existing spring line, and ARCOM will reject profile mismatches on visible elevations. We survey the existing arch, document the exact radius and frame width, and submit that documentation with the permit package so the replacement reads as original.

Oversized Openings
Floor-to-ceiling window walls and oversized picture openings on Palm Beach estates regularly exceed 40 square feet of glass per unit. At that scale, design pressure calculations change, laminated glass thickness steps up, and the frame needs internal reinforcement that off-the-shelf units don’t offer. We engineer oversized openings to the same HVHZ standards we use on impact doors, including corner joinery and anchoring that stands up to a direct-hit storm load.

Trusted Brands We Service in Palm Beach
Winslow Windows & Doors is an authorized installer for eight premium manufacturers, and for Palm Beach custom work we lean most heavily on CGI, CWS, and ES Windows. These are the brands whose product lines and rough-opening tolerances we know well enough to quote accurately, and whose tech reps answer our calls when a radius dimension needs field confirmation. We stock common hardware and weatherstripping components for these lines, which means a repair part doesn’t leave your window inoperable while we wait on a cross-country shipment. Fast turnaround on diagnostics keeps your permit timeline intact.
Common Custom & Geometric Windows Problems We See in Palm Beach Homes
These are the failure modes we see most often on the island. If any sound familiar, call us before the damage compounds.
- Salt-air frame corrosion from two directions. Palm Beach sits between the Atlantic Ocean and Lake Worth Lagoon, so every window gets salt-laden air from both the east and the west. Aluminum frames and hardware on custom geometric shapes typically fail within 7 to 12 years here, binding sashes and crumbling weatherstripping far earlier than mainland coastal homes experience.
- Lost impact rating from bad original installation. An impact-rated glass unit is only impact-rated in an impact-rated frame, and the frame is only as strong as the shims and anchors behind it. We regularly find custom units on Palm Beach homes where the original installer shimmed the jamb incorrectly, which voids the large-missile rating and triggers a full permit review when ARCOM-visible repairs become necessary.
- Binding arched and curved sashes from barrier-island settlement. Unequal soil settlement on a barrier island moves foundations by fractions of an inch over decades. That’s enough to change razor-thin clearances in arched and curved sashes from glide-smooth to jammed-shut. Realigning the frame is the only fix; forcing the window damages the hardware and the frame corner joints.
- Hidden framing rot behind old steel casements. Original steel casement windows on 1920s-to-1940s Palm Beach estates were bedded in mortar, and once the seal fails, salt air and rainwater work their way into the wood buck framing behind the jamb. We don’t know the full scope until the old unit comes out, which is why our Palm Beach quotes always include a written allowance for reframing and flashing rather than a vague “we’ll see what we find” clause.
Pricing for Custom & Geometric Windows in Palm Beach, FL
Custom geometric window work in Palm Beach runs higher than straightforward rectangle replacement because every unit carries design, engineering, and permitting costs that mainland jobs don’t. Here are the anchors we use when we quote on the island:
- Custom impact geometric units (triangle, trapezoid, octagon): $1,200-$2,800 per window installed, depending on size, glass package, and frame finish.
- Arched and curved impact windows matching Mizner-era profiles: $2,500-$5,000 per opening, with radius documentation and ARCOM submittal support included.
- Oversized openings (40+ square feet of glass, reinforced frame): $4,000-$8,000 per unit, engineered to HVHZ design pressures for your specific wind zone.
- Whole-home custom re-glazing on a historic Palm Beach estate: $40,000-$120,000+, depending on unit count, visible-elevation profile requirements, and hidden framing conditions discovered during removal.
The factors that move price in Palm Beach specifically: ARCOM’s monthly submittal deadline (a missed deadline can delay permit issuance by three to four weeks, and delays cost money on multi-unit jobs), salt-air conditions that require stainless or coated hardware upgrades, and the structural reframing that older Mizner-era walls often demand once we expose the rough opening. Every Winslow quote is a written line-item document, not a verbal estimate, and we stand behind it with the Done Right Promise. If it’s not done right, Ed makes it right.
What Custom & Geometric Windows Costs in Palm Beach
Let’s put the numbers in plain terms. Standard impact windows across Palm Beach generally run $800 to $1,500 per window installed when the opening is a simple rectangle and the frame is in good condition. Impact single-hung units step up to $900 to $1,800. True custom work, where radius matching, ARCOM documentation, and heavier glass are involved, lands between $2,500 and $5,000 per window. Whole-home packages on island estates range from $8,000 to over $25,000 depending on unit count, wind zone, floor height (upper-floor installations cost more due to access), and frame material.
The best way to know your number is a free in-home measure. We’ll document every opening, check for hidden frame rot before you commit to a contract, and hand you a written quote with allowances for anything we can’t see until demo. Call (561) 782-7525 and we’ll schedule it.
Florida Pays You Back
The incentives stack in a meaningful way for Palm Beach homeowners. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and impact-resistant windows and doors clearly qualify. Florida also exempts impact-resistant windows and doors from sales tax, which on a $30,000 project saves you roughly $1,800 to $2,100 depending on your county’s current rate. The federal 25C energy credit can return 30% of product cost on qualifying units, up to $600 per year. And once your wind-mitigation inspection is on file, most carriers in Palm Beach cut the windstorm portion of the premium by around 25%. The inspection itself runs $75 to $150. We can’t promise a specific credit or premium reduction; your carrier and your program eligibility set the final numbers. But the path to every one of these incentives starts with impact-rated glass, and we install it correctly the first time.
One more thing worth knowing before you compare options: impact windows versus hurricane shutters isn’t really a close call on Palm Beach’s exposed barrier island. Shutters require someone to hang panels before every storm and leave the home dark and sealed when the power goes out. Impact glass is always in place, no panels to store, no pre-storm scramble. That’s why ARCOM-approved impact windows command a premium on island resale listings.

FAQs - Custom & Geometric Windows in Palm Beach
Yes, and this catches a lot of homeowners off guard. The Town of Palm Beach’s Architectural Commission requires that window and door replacements on designated historic properties match original profiles and character, even when you’re replacing a single unit rather than doing a whole-facade renovation. That means the replacement arch radius, frame width, mullion pattern, and finish all need to align with the original design, while simultaneously carrying current Florida Building Code wind-load ratings and Miami-Dade NOA. This dual compliance burden doesn’t exist in West Palm Beach or Greenacres. Call (561) 782-7525 and we’ll check your property’s historic status and submittal requirements before you spend a dollar on design.
The Architectural Commission meets on a set monthly schedule, and every window or door project on a designated historic property needs ARCOM pre-approval before you can even pull a building permit. If your submittal package misses the deadline, you wait until the next month’s meeting, which pushes your permit and your fabrication timeline back three to four weeks in one shot. We build ARCOM submittal dates into every Palm Beach project schedule so this doesn’t blindside you mid-project.
Yes, in most cases. Once your impact windows carry the proper Florida Product Approval and your wind-mitigation inspection documents the installation, most carriers in Palm Beach reduce the windstorm portion of your premium by roughly 25%. The inspection itself typically costs $75 to $150, and we can connect you with a licensed inspector who knows Palm Beach’s barrier-island wind zone requirements. Your exact discount depends on your carrier and your home’s overall mitigation profile, so talk to your agent for a specific number.
You can’t always know for certain, and that’s exactly why our Palm Beach quotes are structured the way they are. We inspect accessible areas during the free measure, but the truth only appears when the old window comes out. On older island homes, especially Mizner-era steel casements bedded in mortar, we almost always find at least some degree of hidden wood rot. That’s why every Winslow quote includes written allowances for reframing, flashing, and any code-required upgrades, and why we price each change order in writing before our crew touches the masonry. You’ll never get a surprise invoice from us.
Yes. Palm Beach is under 0.5 miles wide at most points, so the distance between the Atlantic Ocean and Lake Worth Lagoon doesn’t provide enough inland buffer to exempt either exposure from the high-velocity hurricane zone. Every window opening on the island, regardless of which side of the house it faces, must meet HVHZ wind-load and impact requirements. A “non-impact” quote from a mainland contractor is a red flag on this island. We don’t install anything here that can’t be backed with the right Florida Product Approval documentation.
How Winslow Handles What’s Behind the Wall
Opening up an older Palm Beach wall for a window replacement is where most quotes fall apart. You might expect a clean swap, and then the old jamb comes out and reveals undersized framing, failed waterproofing, or wiring and plumbing that violates current code once the wall cavity is exposed. On South Ocean Boulevard we opened a 1930s Mediterranean Revival wall to replace a corroded steel casement and found undersized framing and failed waterproofing hidden behind the original jamb. Our crew wrote a change order for reframing and flashing before touching the masonry, then installed a custom PGT arched impact unit with a laminated glass interlayer to satisfy ARCOM’s profile match and HVHZ wind-load requirements. No surprises, no silent upcharges. That’s how we work on every Palm Beach job.
