Fast, Reliable Window Replacement Across West Palm Beach
Window replacement in West Palm Beach runs $800 to $1,500 per impact-rated window installed, and most whole-home projects land between $8,000 and $25,000 for a typical 1950s CBS ranch or 1920s Mediterranean Revival home. The work usually takes one to two days once your custom units arrive, with fabrication running four to six weeks for impact glazing. Call (561) 468-6136 and a live person answers, day or night. That matters when a corroded frame finally gives out at 10 p.m. and you need to know someone’s coming.

We’ve spent years working the blocks between El Cid, Flamingo Park, Grandview Heights, and the mid-century neighborhoods stretching west toward the Turnpike. Our crews know which homes have original steel casements set directly in mortar without a single wood buck, and which ones were built after 1960 with proper framing we can work with faster. That local knowledge changes the quote you get and the headaches you don’t.
Ed Winslow’s name is on the door and on every job we do. That’s the standard. If it’s not done right, we make it right, period.
Why Winslow Windows & Doors Is West Palm Beach’s Preferred Window Replacement Company
A neighbor you can call at 2 a.m. and someone will actually answer. That’s not a slogan here. It’s how we’ve run this business since Ed Winslow founded it in 2011. When a salt-corroded window frame fails during a summer squall off Lake Worth Lagoon, you don’t want a call center in another state. You want a local crew that knows the difference between a 1926 El Cid casement and a 1964 CBS single-hung.
West Palm Beach homeowners have hired us for years because we show up when we say we will, our technicians arrive in uniform and background-checked, and every estimate is a real line-item quote you can hold us to. No vague “materials and labor” line. No change order surprises once the wall is open. Our published address and license number are on every proposal, and Ed’s personal accountability sits behind the Done Right Promise. If it’s not done right, we come back and make it right.
We also offer a permanent 10% discount for seniors and veterans, $40 off any repair over $200, and free second opinions on any written estimate another contractor gave you. Bring us their quote. We’ll show you what they missed, and we won’t charge you a dime to do it. That free second opinion has saved West Palm Beach homeowners thousands, especially in the historic districts where out-of-area contractors routinely lowball the quote and then discover the missing wood bucks.
Our Window Replacement Services in West Palm Beach
Every opening, every home, every Historic Preservation Board requirement is different here. We handle the full range of Window Replacement work, but these are the services West Palm Beach homeowners call us for most.
Full Frame Replacement
When the entire existing window assembly comes out down to the rough opening, that’s full frame replacement. In West Palm Beach, this is the right call for homes where salt air has eaten the original frame, or where the window was set directly into 1920s masonry with no wood buck. We also install West Palm Beach Sliding Glass & Patio Doors using the same full-frame method when patio openings need replacement. We fabricate new pressure-treated bucks on site, anchor them into the block, and set the new impact unit the way the Florida Building Code actually requires. This is the job that separates a licensed local crew from a big-box subcontractor.
For mid-century CBS homes west of Dixie Highway, full frame replacement also lets us address the original window openings that were never properly flashed. Those gaps are where West Palm Beach’s wind-driven rains find their way in. We flash every opening before the new unit goes in, which is why our installs stay dry through hurricane season.

Insert Window Replacement
If the existing frame is still square, structurally sound, and properly anchored, an insert replacement preserves the trim and interior finishes while swapping in a brand-new impact-rated sash and glazing. In El Cid and Flamingo Park, the Historic Preservation Board often prefers inserts because they disturb less of the original opening. We work with that. Our team has guided dozens of HPB applications through approval, matching muntin patterns and profiles to what the board expects to see.
Inserts cost less than full frame replacements and take about half the install time per opening, assuming the frame is in decent condition. In salt-heavy neighborhoods near Lake Worth Lagoon, that assumption needs checking. Aluminum frames corrode from the inside out here, and a frame that looks fine from the street can be structurally compromised behind the stucco. We check before we quote, not after we open the wall.

Vinyl Replacement Windows
Vinyl windows make sense in West Palm Beach when the home is newer construction with intact wood bucks and you’re replacing a failed aluminum unit. Vinyl won’t corrode the way aluminum does in salt air, and modern vinyl extrusions hold up well in our UV-heavy climate. We install vinyl replacement windows from brands like PGT, with reinforced meeting rails and stainless hardware specified for coastal exposure.
What we won’t do is sell you a bargain vinyl insert for a 1920s masonry opening that needs a full buck refabrication and HPB sign-off. That’s the exact package out-of-area crews pitch, and it’s why their inspections fail. We’d rather tell you the truth up front and quote the job once than sell you twice.

Energy-Efficient Upgrade
West Palm Beach’s cooling season runs most of the year, and single-pane aluminum windows from the 1950s and 1960s are thermal sieves. Our Energy-Efficient Windows - West Palm Beach upgrades pair Low-E insulated glass units with impact-rated laminated glass, giving you one window that handles both the wind load and the AC bill. We’ll match the glazing package to the design pressure required for your specific opening and floor height in West Palm Beach’s wind zone.
And yes, Low-E glass can coexist with historic requirements. The HPB cares about what the window looks like from the street: the profile, the muntin pattern, the material. The glass coating is invisible. We’ll spec a Low-E insulated unit inside a historically sympathetic frame and get both approvals in one pass.

Trusted Brands We Service in West Palm Beach
We’re an authorized installer for PGT, CGI, CWS, ES Windows repair in West Palm Beach, ECO Window Systems, Mr-Glass, Therma-Tru. That’s not a random list. It’s the lineup that gives West Palm Beach homeowners real options across budget, wind rating, and aesthetic, whether you live in a 1926 Mediterranean Revival in El Cid or a 1970s CBS home off Forest Hill Boulevard.
For historic district work, CGI’s impact-rated casement line has profiles that satisfy the HPB without looking like a slab of modern glass dropped into a 100-year-old opening. For mid-century homes, PGT’s WinGuard series remains the most installed impact window in Palm Beach County. We stock local inventory of gaskets, hardware, and weatherstripping for these lines, which means when a latch fails or a balance breaks, we don’t order parts from Ohio and make you wait three weeks. We fix it same week.

Common Window Replacement Problems We See in West Palm Beach Homes
- Original 1920s steel casements set directly in mortar. These homes were built before anyone thought about wood bucks. The steel frame sits in the masonry opening with nothing between it and the block. Fifty or a hundred years later, you have rust, water intrusion, and an opening that won’t accept a modern unit without full buck fabrication first.
- Salt-air corrosion on aluminum frames and hardware. West Palm Beach sits directly on Lake Worth Lagoon, and the Atlantic’s just across Palm Beach island. That salt mist finds aluminum window frames, latches, and weatherstripping and eats them in five to ten years. Frames that still look okay from a distance stop locking, stop sealing, and lose whatever impact rating they once had long before they fail visually.
- Out-of-area quotes that ignore HPB review entirely. A contractor from Boynton Beach quotes a standard vinyl insert for an El Cid casement, never mentions the Historic Preservation Board, and then the inspection fails. The homeowner’s project stalls for weeks, and the change order lands. We’ve seen this pattern enough times that we walked the HPB process into every historic-district quote from the start.
- Rotted or missing wood bucks in mid-century CBS construction. Homes built from the 1940s through the 1960s in West Palm Beach were block construction, and the window openings often got undersized or improperly flashed wood bucking. Fifty years of humidity and the occasional storm intrusion rots those bucks out completely. When you open the wall for a replacement, there’s nothing left to anchor to. That’s a fabrication job, not a swap.
Pricing for Window Replacement in West Palm Beach, FL
Here are the numbers we actually quote in West Palm Beach. A standard impact-rated single-hung replacement window runs $900 to $1,800 installed. Impact windows generally fall between $800 and $1,500 per opening, depending on size and glazing package. Large custom openings or architectural shapes in historic homes land between $2,500 and $5,000. Whole-home packages across a typical three-bedroom CBS home run $8,000 to $25,000 or more, depending on how many openings, whether we’re doing full frame or inserts, and what the HPB requires if you’re in a historic district.
What moves the price here specifically: opening count, wind zone design pressure for your specific location in West Palm Beach, floor height (second-story openings require higher structural ratings), frame material, and whether we’re fabricating new wood bucks. In El Cid or Flamingo Park, budget an extra half-day per opening for buck fabrication and inspection, plus HPB application time. West Palm Beach historic work costs more than the same job in Royal Palm Beach, and there’s a reason: the dual approval process and the masonry anchoring work are real, and skipping either one fails inspection.

What Window Replacement Costs in West Palm Beach
We already put the ranges above, but let’s talk about why the coastal-spec version of the same job costs more than the inland-spec version. Salt air decides materials in West Palm Beach. An aluminum frame with standard hardware will corrode within a decade near Lake Worth Lagoon, especially on the east side of I-95 and in neighborhoods like El Cid that sit minutes from the water. We specify stainless or hot-dip galvanized hardware, marine-grade finishes, and sealed frame joints instead. That’s the difference between a $900 standard unit and a $1,300 coastal-spec unit, and the cheap spec costs more within ten years because you’re replacing it twice. That math doesn’t show up on a big-box quote.
Same logic applies to impact ratings. The county’s design wind speed under the Florida Building Code is roughly 150 mph, which makes impact-rated glazing the practical requirement for any permitted replacement. Your homeowners insurance carrier expects it too. A window that meets Miami-Dade NOA or Florida Product Approval standards, with the design pressure matched to your specific opening, is what actually protects your home in a storm. Ratings above +/-100 are rarely needed for ground-floor residential openings here, but every opening gets calculated, not guessed.
Impact windows versus hurricane shutters is another honest comparison worth understanding. Shutters only protect you when you’ve had warning, the panels are on, and someone’s home to hang them. Impact windows protect you permanently, no panels to hang, no storm-prep scramble. For West Palm Beach homeowners who travel in the summer or own homes they don’t live in year-round, that’s the deciding factor. The same logic applies to Impact Garage Doors in West Palm Beach - permanent protection with no prep required. It’s why we install ten times more impact windows than we ever recommend shutter retrofits for.
We’ll measure every opening, spec every unit, and hand you a written quote that holds. Call (561) 468-6136 to schedule your free in-home measure.
Florida Pays You Back
West Palm Beach homeowners can stack a few incentives that meaningfully offset the cost. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and impact windows qualify in most cases. Florida also exempts impact-resistant windows and doors from sales tax. At the federal level, the 25C energy credit covers 30% of the product cost on qualifying energy-efficient units, up to $600 per year. And once your impact windows are installed, a wind-mitigation inspection, typically $75 to $150, can unlock windstorm premium credits averaging around 25% on the windstorm portion of your policy.
We’re not tax advisors or insurance agents, and every program and carrier sets their own final numbers. But we’ll point you to the programs we know exist and help you document the install correctly so you can claim what you’re owed. The inspection paperwork, the product approval numbers, the NOA references, they’re all included in your job file.

FAQs - Window Replacement in West Palm Beach
Yes. Homes in West Palm Beach’s HPB-designated neighborhoods, including El Cid, Flamingo Park, and Grandview Heights, require simultaneous approval from the Historic Preservation Board for the profile, muntin pattern, and material of replacement windows, plus a standard building permit certifying Florida Building Code compliance, including impact glazing. The HPB reviews what the window looks like from the street; the permit review confirms it’ll survive a storm. We manage both applications for you and have guided dozens of historic-district replacements through this dual-track process. Call (561) 468-6136 if you’d like us to look up your specific address and tell you exactly which reviews apply.
Because the original steel or wood casement frames in 1920s West Palm Beach masonry homes were set directly in mortar with no wood buck at all. The frame sits against bare block. Modern impact units must be anchored to a properly dimensioned, pressure-treated wood buck that’s bolted into the masonry and sealed before the window is set into it. In El Cid, we retrofitted a 1926 Mediterranean Revival CBS home where the original steel casements were set directly in mortar. Our crew fabricated pressure-treated bucks on site, anchored them into the block, and installed Miami-Dade NOA impact-rated casement windows from CGI with matching historic profiles. That project required an extra half-day per opening for buck fabrication and inspection, which the homeowner’s previous out-of-area quote had entirely missed.
Salt air from Lake Worth Lagoon and the Atlantic corrodes aluminum frames, hardware, and weatherstripping far faster than inland Florida markets. Frames that would last 30 years in Royal Palm Beach can show significant corrosion within 5 to 10 years near the coast in West Palm Beach. That corrosion causes operation failures, breaks the frame’s seal, and eventually voids the impact rating. We specify stainless or hot-dip galvanized hardware, marine-grade frame finishes, and sealed joints for coastal-spec installs. The upgrade costs around $200 to $400 per window and keeps the unit functional for decades instead of a decade. Call (561) 468-6136 to have us assess what salt air has already done to your frames.
West Palm Beach falls under Palm Beach County’s Florida Building Code wind zone, with a design wind speed around 150 mph. Replacement windows must meet Miami-Dade NOA or Florida Product Approval standards for impact resistance, with design pressures matched to your specific opening, floor height, and exposure. Ground-floor openings in a standard subdivision typically require design pressures well under +/-100, but every opening gets calculated individually. Never accept a window rated above +/-100 for a standard single-story opening, it’s pure markup with no added protection. We spec every unit to the exact design pressure your opening requires, nothing less, nothing more.
Yes. The Historic Preservation Board reviews the visual profile, muntin pattern, and frame material from the street. Low-E coating and insulated glass construction are invisible to that review. We’ve installed Low-E, impact-rated insulated glass units inside historically sympathetic frames in El Cid, Flamingo Park, and Grandview Heights, passing HPB approval and receiving the energy performance at the same time. The glass package affects the window’s thermal performance; the frame profile is what the board sees. Call (561) 468-6136 for a free consultation, and we’ll show you examples of recent HPB-approved installs near you.
