Fast, Reliable Custom & Geometric Windows Across West Palm Beach
Custom and geometric impact windows in West Palm Beach run $2,500 to $5,000 per opening on average, and most projects take four to six weeks from order to installation because of the custom fabrication involved. If you’re in El Cid, Flamingo Park, or anywhere along the Lake Worth Lagoon, you already know that replacing a non-standard window here isn’t a trip to the big-box aisle. You need an installer who understands historic district rules, masonry anchoring, and the salt air that eats standard aluminum hardware. Call Winslow Windows & Doors at (561) 468-6136 for a free in-home measure and a written quote with no surprises.

Ed Winslow’s name is on the door, and on every job we do in West Palm Beach. We’ve been installing Impact Windows in West Palm Beach - custom and geometric - long enough to know exactly what’s behind those old plaster walls before we open them up.
Why Winslow Windows & Doors Is West Palm Beach’s Preferred Custom & Geometric Windows Company
We’re not a national chain with a rotating crew roster. Winslow Windows & Doors is locally owned and owner-operated, and every technician who knocks on a West Palm Beach door is background-checked and in uniform. You’ll know who’s at your door before the truck pulls up. Our published address and license number are available to any homeowner who wants them, and our Custom & Geometric Windows team does this specific work every single week, not occasionally between vinyl retrofits.
West Palm Beach homeowners call us because we answer the phone. Not a voicemail loop, not a call center. A live person picks up, 24/7. When a permit inspection in El Cid turns up an issue at 4 p.m. on a Friday, you can reach us. When you’re weighing whether an arched fixed window can actually meet the 150 mph design pressure requirement, we’ll walk you through the options over the phone instead of making you wait for a callback. That’s the difference between a contractor and a neighbor.
Wind Zone Reality in West Palm Beach
Palm Beach County sits in one of the highest wind design zones in Florida, with a design wind speed around 150 mph under the Florida Building Code. For custom and geometric windows, Shingle, Tile & Metal Roofing - West Palm Beach neighbors face similar wind demands, and here that means almost every replacement, including historic-profile recreations, must carry impact-rated glazing and Miami-Dade or Florida Product Approval numbers matched to the specific opening. We won’t install a unit that doesn’t meet the design pressure your opening requires. That’s not optional, and we’ve walked away from manufacturers who think a generic rating will satisfy a West Palm Beach inspector. West Palm Beach’s location directly on the Lake Worth Lagoon with the Atlantic just across Palm Beach island means the wind load is real, and the salt exposure is relentless. Together they dictate both the product and the installation method.
Our Custom & Geometric Windows Services in West Palm Beach
Custom Impact Windows
Most of West Palm Beach’s housing stock is mid-century concrete block structure from the 1940s through 1960s, and those openings are rarely square. West Palm Beach homes from this era were built with masonry openings that have settled, shifted, or were never perfectly dimensioned in the first place. Our custom impact windows are built to the exact opening measurements we take on site, not pulled from a stock size chart. Each unit carries the Florida Product Approval and design pressure rating matched to its specific position in the home.

Geometric & Shaped Windows
Triangles, trapezoids, pentagons, parallelograms. If the shape has a name, we’ve fabricated it for a West Palm Beach project. Geometric windows are common above entry doors, in stairwells, and on the street-facing elevations of houses throughout the city’s historic neighborhoods. The challenge in West Palm Beach isn’t just the glazing, it’s that the structural opening around a geometric unit often needs real carpentry work before the window can be set. We handle that in-house, not through a sub.

Arched & Curved Windows
Arched windows are a signature of the 1920s, 1930s, and 1940s Mediterranean Revival stock that defines El Cid, Grandview Heights, and Flamingo Park. Replacing one means matching the original radius, muntin pattern, and sightline profile closely enough to satisfy the Historic Preservation Board. It also means the impact glazing has to be curved or built into a curved frame that can carry the design pressure. We have installed arched impact units in West Palm Beach that most contractors would have told you were unavailable, because the right manufacturer relationships and the right engineering make them possible.

Oversized Openings
When a West Palm Beach homeowner wants a 96-inch-by-96-inch fixed picture window, or a 12-foot sliding glass wall with a geometric transom above it, the engineering burden multiplies. Wind load increases with surface area, so a large custom opening often requires structurally reinforced framing and a heavier extrusion. Our team calculates the design pressure for the specific opening and location, confirms the unit meets it, and then verifies the surrounding structure can carry it. If it can’t, we fix the structure before the unit goes in, never after.

Trusted Brands We Service in West Palm Beach
Winslow Windows & Doors is an authorized installer for PGT, CGI, CWS, and ES Windows, among others, and we also handle Therma Tru in West Palm Beach entry systems. For West Palm Beach’s historic district work, ES Windows is frequently the right choice because their profiles can be matched to original steel casement sightlines. PGT and CGI carry broad Florida Product Approval coverage across impact configurations, and CWS fills gaps for specialized architectural shapes. Because we install these brands regularly for West Palm Beach customers, we know their lead times, their approval documentation, and their warranty procedures.
Common Custom & Geometric Windows Problems We See in West Palm Beach Homes
- Missing or rotted wood bucks in historic CBS homes. In 1920s and 1930s construction, window frames were often set directly in mortar with no wood buck at all. When we pull an old window in El Cid or Flamingo Park, the absence of a buck means we fabricate and anchor a new pressure-treated buck into the block before the impact unit can be set. Out-of-area contractors routinely miss this in their quotes, which is how change orders happen.
- Salt-air corrosion from Lake Worth Lagoon. East-facing openings near the water get hit with airborne salt every single day. Uncoated aluminum jamb tracks, hinges, and weatherstripping corrode within a few years. We see hardware failures on geometric windows in West Palm Beach that would never occur in an inland Florida market, which is why we specify marine-grade coatings and hardware for lagoon-adjacent homes.
- HPB approval problems on already-ordered sashes. A homeowner orders a custom arched window with a muntin pattern the contractor likes, but the Historic Preservation Board rejects it because the profile doesn’t match the original. Now the sashes are already in fabrication and the homeowner is stuck. We get HPB sign-off on profile, muntin pattern, and material before anything goes into production.
- Non-impact units installed before a claim is filed. A previous contractor installed a non-rated custom window in a West Palm Beach home, and now the homeowner can’t get windstorm insurance credits or full claim coverage. We replace these with properly rated impact units and provide the documentation for the insurance carrier and the inspection report.
Pricing for Custom & Geometric Windows in West Palm Beach, FL
A custom or geometric impact window in West Palm Beach typically runs $2,500 to $5,000 per opening installed. Arched units in El Cid or Flamingo Park that require HPB-matched profiles and marine-grade hardware trend toward the top of that range. A large fixed half-round or pentagon with a 150 mph design pressure rating will land around $4,000 to $6,500 on its own. Whole-home packages with multiple custom openings typically span $8,000 to $25,000 and up, depending on the count and the complexity.
What moves the price here is the labor behind the opening, not just the glass. If the original frame was set directly in mortar, expect an extra half-day per opening for buck fabrication and anchoring. If the HPB requires a custom muntin pattern that has to be engineered and fabricated from scratch, that adds to both lead time and cost. If the home sits east of Olive Avenue near the lagoon, we spec marine-grade components that cost more upfront and save you from replacing corroded hardware in five years. Call (561) 468-6136 to schedule a free in-home measure and get a written, line-item quote. Upfront pricing. No surprises on the invoice.
What Custom & Geometric Windows Costs in West Palm Beach
Impact windows generally land between $800 and $1,500 per window installed in West Palm Beach when we’re talking about stock rectangles. Custom impact windows add fabrication complexity and run $2,500 to $5,000 per opening. A single impact single-hung starts around $900 and tops out near $1,800 depending on size and frame material. Large or custom openings, including oversized fixed glass and geometric shapes, sit in the $2,500 to $5,000 range. Whole-home packages across a typical three-bedroom West Palm Beach house span $8,000 to $25,000 and up.
We don’t give you a range over the phone and then pad the invoice later. The free in-home measure is how we build your actual price, and we’ll write it down item by item before you sign anything.

The Inspection and Allowance: How We Protect You
Opening up an older West Palm Beach home for Roof Replacement & Installation in West Palm Beach or window work is the moment a remodel quote either holds or falls apart. Behind the plaster and lath, we often find outdated wiring that has to be brought to current code because the inspector will require it once the wall is open. We find undersized or damaged framing around the existing window. We find failed waterproofing at the sill and along the jamb that has been quietly letting water into the block for years. And we find code upgrades, required by the permit, that a basic quote never mentioned.
The way we handle it is the inspection first, the allowance written into the contract, and any surprise priced and approved in writing before we touch it. A contractor who hands you a fixed quote and then sends change orders is not doing you a favor by “sticking to the number.” We’d rather tell you the truth at the beginning and give you a number you can plan around.
Florida Pays You Back
West Palm Beach homeowners can stack several programs to offset custom impact window costs. My Safe Florida Home matching grants can contribute up to $10,000 toward qualifying wind-mitigation upgrades, and custom impact windows are a primary qualifying item. Florida also exempts impact-resistant windows and doors from sales tax. At the federal level, the 25C energy credit covers 30% of product cost, up to $600 per year, on qualifying energy-efficient units. After installation, a windstorm-mitigation inspection typically runs $75 to $150, and many carriers credit the windstorm portion of the premium by roughly 25% when the home qualifies. Programs and carrier decisions set the final numbers, so we’ll point you to the right documentation but we won’t overpromise.
Impact Windows vs. Hurricane Shutters in West Palm Beach
Shutters do a job, and we respect the homeowners who choose them. But in West Palm Beach, where salt air means any exterior component is going to take a beating, permanent impact protection has a real advantage. You don’t have to carry panels out of storage, line up tracks in the dark, or worry about whether the shutters are installed correctly when the storm is already overhead. A properly rated impact unit is always in place, always working, and qualifies for the same insurance documentation without any additional labor. For custom and geometric windows in historic homes, shutters can also fight with the original architecture in ways a faithful impact window replacement never does.
Homes with a History: West Palm Beach’s Dual Approvals
In West Palm Beach’s Historic Preservation Board-designated neighborhoods, specifically El Cid and Flamingo Park, custom and geometric impact windows must simultaneously satisfy HPB approvals for original profile, muntin pattern, and material while meeting Florida Building Code impact-glazing mandates. This dual-review process doesn’t exist in neighboring Boynton Beach or Delray Beach, where code compliance is the only approval you need. In West Palm Beach, the HPB can reject a window design that the building department would approve all day long. We’ve handled both reviews, and we sequence them deliberately: HPB sign-off first, then fabrication, then building department inspection. Sending an already-fabricated window through HPB review after the fact is the most expensive mistake you can make on a historic West Palm Beach home.
We saw the cost of skipping that sequence on a 1930s Mediterranean Revival in El Cid, where our crew replaced a sun-damaged arched casement with a custom impact-rated unit from ES Windows that matched the original steel sightlines. The original frame was set directly in mortar with no wood buck, so we fabricated and anchored new pressure-treated bucks into the CBS before setting the insulated glass unit. We also discovered corroded aluminum jamb hardware from Lake Worth Lagoon salt air and replaced all weatherstripping with marine-grade material during the same visit. A contractor unfamiliar with that house, that neighborhood, and that approval process would have ordered the wrong profile, missed the buck entirely, and handed the homeowner a change order on the back end.

FAQs - Custom & Geometric Windows in West Palm Beach
In those districts, a permit that opens up an old wall usually triggers a requirement to bring any hidden framing, wiring, and waterproofing up to current code before the inspector will sign off. When we remove an original 1920s window in El Cid or Flamingo Park, the original frame is often set directly in mortar with no wood buck at all. That means we fabricate and anchor a new pressure-treated buck into the CBS before the impact unit can be set. You’re not paying for re-framing because we prefer it, you’re paying because the permit requires it, and we’re not going to let you discover that three weeks into the project. Call (561) 468-6136 to get an inspection scheduled before you plan the remodel budget.
A custom arched impact window in the Historic Preservation Board districts needs HPB sign-off on the profile, muntin pattern, and material to match the original window, plus a Florida Building Code impact-glazing approval with the right design pressure for the opening. Those two reviews are separate, they move at different speeds, and they can conflict. We get the HPB approval before fabrication so you’re not paying to re-order sashes. If you’re not sure whether your home is in an HPB district, call (561) 468-6136 and we’ll check the map with you.
Salt air from Lake Worth Lagoon accelerates corrosion on uncoated aluminum jamb tracks, hinges, and weatherstripping, and geometric windows have more hardware per square foot than standard rectangles. Homes east of Olive Avenue and near the water see hardware failures in a few years that inland West Palm Beach homes might not see for a decade. We specify marine-grade coatings and hardware for lagoon-adjacent installations, which adds a little to the quote and keeps the window operating for years longer. If your current hardware is already pitted or binding, call (561) 468-6136 for an assessment.
Because opening up an older West Palm Beach wall can reveal outdated wiring, undersized framing, failed waterproofing, and code upgrades that a permit inspector will require. An inspection and allowance means the unknown is priced ahead of time instead of arriving as a surprise change order. Any additional work gets priced and approved in writing before we touch it. We’d rather you know the real number on day one. Call (561) 468-6136 for a free estimate that includes the allowance conversation.
Yes, if it’s engineered and fabricated as an impact-rated unit from the start. The design pressure increases with surface area, so a large half-round or pentagon often requires a heavier extrusion and reinforced frame anchoring. Our job is to calculate the pressure for the specific opening and elevation, confirm the unit meets it, and verify the surrounding structure can carry it. If the opening can’t carry the load, we fix the structure before the unit goes in. If a contractor tells you a large geometric window can’t be impact-rated in West Palm Beach, get a second opinion at (561) 468-6136.
