Fast, Reliable Window Replacement Across Palm Beach
Window replacement in Palm Beach, FL typically costs between $800 and $1,500 per opening for impact-rated units, with custom historic-profile fabrications running $2,500 to $5,000 per window. Most projects on the island take six to eight weeks from ARB submission to final install, which is why we tell every homeowner the same thing: start early, especially if you’re a seasonal resident flying north in May. Our crews know the town’s review process, its historic housing stock, and its salt-air demands better than any off-island contractor. Call (561) 468-6136 for a free in-home measure and a written quote that accounts for ARB requirements from day one.

Why Winslow Windows & Doors Is Palm Beach’s Preferred Window Replacement Company
Ed Winslow put his name on this business in 2011, and that name is on every job we do in Palm Beach. We’re not a franchise with a rotating cast of subcontractors. We’re an owner-operated company with a published address and license number, and the person answering our phone at 2 a.m. is a real human being, not a voicemail tree.
Our Palm Beach customers come back to us because we know what the Architectural Review Board expects before we ever submit a drawing. We’ve replaced arched Mizner-era casements on Seaview Avenue, matched original steel profiles on Wells Road, and handled mid-century CBS homes on the interior streets where even a simple fenestration change triggers board review. Our Window Replacement team includes fabricators and installers who have worked specifically with Mediterranean Revival profiles for years, not weeks.
We’re background-checked and uniformed on every visit. You’ll know who’s at your door before the truck pulls up. That matters on an island where security and discretion are non-negotiable.
Our Window Replacement Services in Palm Beach
Full Frame Replacement
Full frame replacement means removing the entire existing window down to the rough opening and installing a new unit with new jambs, sills, and trim. In Palm Beach, this is often the only option when ARB approval requires changing the window’s profile from a generic rectangular opening to an arched or multi-lite configuration. It’s also the right call when the original steel casement has corroded through from decades of dual salt exposure off the Atlantic and the Intracoastal. We pull the old frame, inspect the opening for rot or termite damage, and rebuild with marine-grade materials.

Insert Window Replacement
Insert replacement keeps the existing frame and slides a new sash and glass unit inside it. This works well for Palm Beach’s mid-century CBS homes where the original frame is square, sound, and acceptable to ARB as-is. It’s faster than full frame work and typically costs less, but it won’t fix a frame that’s pitted or sagging. We’ll tell you honestly which approach your house needs. On this island, guessing wrong means a board rejection and a re-fabrication.

Vinyl Replacement Windows
Vinyl makes sense for many Palm Beach homeowners because it never corrodes, never needs paint, and handles the town’s salt-laden air without the pitting you see on untreated aluminum. But ARB approval for vinyl on historically protected structures is far from automatic. For Mediterranean Revival homes on the landmark register, the board often requires a specific profile, finish, or material. We’ll help you submit exactly what ARB wants to see, so you’re not paying for a doomed application. Call (561) 468-6136 and we’ll walk your property first.

Energy-Efficient Upgrade
Most windows we install in Palm Beach are Low-E insulated impact units, because they solve two problems at once. They block windborne debris and they cut the solar heat gain that drives August cooling bills through the roof. On a west-facing wall along the Intracoastal, that afternoon sun is relentless. A properly specified Low-E glass package can drop your cooling load noticeably while the laminated interlayer gives you large-missile protection. For Palm Beach, this is the practical choice, not an upsell.

Trusted Brands We Service in Palm Beach
We’re authorized installers for PGT, CGI, and CWS, among others, and we stock local parts for fast turnaround when a repair or replacement is urgent. For Palm Beach’s historic-profile work, PGT and CGI both offer custom fabrication lines that can replicate arched and multi-lite configurations in an impact-rated product. We specify the right Miami-Dade NOA and Florida Product Approval numbers per opening, and we match design pressures to the actual wind zone rather than slapping a generic +/-100 rating on every window. Window Replacement in Palm Beach demands that level of precision.
Common Window Replacement Problems We See in Palm Beach Homes
- Missed ARB windows. The Architectural Review Board can take six to eight weeks on a historic structure. Seasonal owners who call us in October are already too late for a spring install. Start the process in March, before you leave for the summer.
- Salt corrosion on aluminum frames. Palm Beach sits between the Atlantic and the Intracoastal, so every structure gets salt-laden air from two directions. Untreated aluminum pits within two to three years. Marine-grade finishes and stainless fasteners aren’t optional here.
- ARB rejections on generic rectangular units. You cannot swap an arched 1920s casement for a stock rectangular impact window. The board will reject it, and you’ll pay for re-fabrication. Custom profile matching has to happen before the order goes to the factory.
- Rushing decisions from afar. Too many Palm Beach owners approve window work from New York or Boston in July, sight unseen. A phone camera does not tell you if the mullion profile is right. We send detailed drawings and samples before anything is fabricated.
Pricing for Window Replacement in Palm Beach, FL
Impact windows in Palm Beach generally run $800 to $1,500 per window installed. Impact single-hungs land between $900 and $1,800. Large or custom openings, which are everywhere on this island, run $2,500 to $5,000 per unit. Whole-home packages for a typical Palm Beach estate fall between $8,000 and $25,000 or more depending on opening count, frame material, and wind zone. What moves the price in Palm Beach specifically is the ARB’s custom-fabrication requirement, the floor height, and whether the opening is arched or standard. We give you a written line-item quote before any work begins, and we honor it. No change orders. Call (561) 468-6136 for a free in-home measure.
What Window Replacement Costs in Palm Beach
Here is what you should expect to pay on the island, based on jobs we’ve done in neighborhoods from the North End to the Estate Section:
- Standard impact window (installed): $800-$1,500 per unit
- Impact single-hung: $900-$1,800 per unit
- Custom arched or large-opening unit: $2,500-$5,000 per unit
- Whole-home package: $8,000-$25,000+ depending on opening count and wind zone
Frame material, floor height, and glass package all move the number. On a third-floor oceanfront window, the design pressure requirements climb. On a ground-floor rear-facing window, they don’t. We match the rating to the opening, never to a blanket spec. The quote you get from us is the price you pay. Call (561) 468-6136 for a free measure and written estimate.

Florida Pays You Back
There are real incentives for Palm Beach homeowners who do this work right. My Safe Florida Home matching grants can cover up to $10,000 toward qualifying wind-mitigation upgrades. Florida waives sales tax on impact-resistant windows and doors. The federal 25C energy credit can return 30% of the product cost, up to $600 per year on qualifying units. And after a wind-mitigation inspection, which runs $75 to $150, many carriers credit around 25% on the windstorm portion of your premium. The final numbers are set by the programs and your insurer, not by us, but we’ll point you to every program you’re eligible for and document the work properly so the credits actually land.
Impact Windows vs. Hurricane Shutters: What Palm Beach Homeowners Should Know
Shutters only protect you if someone is home to hang them. Impact windows are always on, always rated, always protecting the opening. On a barrier island where a storm can turn faster than a flight can get you back from up north, that’s not a small distinction. Palm Beach has a huge seasonal population, and too many owners have trusted panels that sat in a garage while a September storm blew through. Impact windows work whether you’re on the island or not. Given the ARB’s appetite for permanent, architecturally appropriate solutions, impact windows are also far easier to get approved than exterior shutter tracks on a Mizner facade.
Palm Beach’s Aging-in-Place Window and Door Reality
Palm Beach’s housing stock was largely built between 1920 and 1950. The people living in it, more and more, are deciding to stay. That means window and door work here is increasingly about aging in place: wider doorways, zero-threshold entries, slip-rated surfaces, and low-maintenance exterior choices for seasonal residents who don’t want to think about paint and corrosion while they’re away. Window replacement inside an existing footprint generally doesn’t need a permit beyond ARB approval. But if you’re widening an opening, moving a door, or altering a structural wall, you’ll need plans and permits, and we pull them for you. A full-frame replacement that keeps the same rough opening is a different animal than an enlargement, and we’ll price both honestly.
Field Story: Seaview Avenue, Palm Beach
On Seaview Avenue, our crew replaced a 1920s Mizner-era arched window with a PGT custom impact-rated casement. We matched the original steel profile and added a laminated glass interlayer for large-missile protection. The homeowner was leaving for the summer in May, so we submitted ARB plans in March and completed installation before their departure. That’s the calendar Palm Beach runs on. We start every historic job by asking when you leave and when you return, because the board’s timeline, not our crew’s, is the real constraint.

FAQs - Window Replacement in Palm Beach
Start six to eight months before you want the work done, and if you’re a seasonal resident, begin the spring before you leave. The ARB review cycle runs roughly six to eight weeks for historic structures, and custom fabrication adds another four to six weeks after approval. Call (561) 468-6136 in March for a May installation, not in October.
Technically you can mix, but we don’t recommend it. Any non-impact opening is a breach point in a storm, and wind pressure does not care which window you protected. Most Palm Beach homeowners go all-impact because the premium credits, sales tax exemption, and My Safe Florida Home grant rewards only apply to the full scope. For an exact quote on your opening count, call (561) 468-6136.
The ARB can approve vinyl in some cases, but it depends on the specific building, its landmark status, and the profile. For many Mediterranean Revival homes, the board requires replication of the original steel-casement look, which means a custom aluminum or steel-clad product, not stock vinyl. We’ll review your property and tell you what’s realistic before you spend a dollar on drawings. Call (561) 468-6136 for a free assessment.
Large-missile windows are rated to withstand a 9-pound 2×4 fired at 34 miles per hour, and they’re required for most openings in Palm Beach’s wind zone, especially first and second floors and anything within 30 feet of grade. Small-missile covers windborne debris that’s lighter and slower. We match the rating to the specific opening and elevation, never a blanket spec. For your exact requirements, call (561) 468-6136.
Yes, especially on west-facing and south-facing walls. Low-E coatings reject a significant portion of solar heat gain while the insulated airspace slows heat transfer into the house. On a Palm Beach afternoon in August, that’s the difference between an AC that cycles and one that never stops. Exact savings depend on your exposure, shading, and current glass, but the direction is consistently downward. Call (561) 468-6136 and we’ll assess your openings and estimate the change.
