Fast, Reliable Impact Windows Across Greenacres
If you own a CBS home in Greenacres built between 1970 and 1990, there’s a very good chance you’re still living with the original aluminum jalousie windows and single-pane sliding glass doors. Those openings were never designed to meet Palm Beach County’s current wind-borne debris requirements, and they’re the first thing an insurance four-point inspection flags. At Winslow Windows & Doors, we replace those non-compliant openings with impact-rated windows and doors that pass code, satisfy insurers, and cut your cooling bill. Call (561) 782-7525 for a free in-home measure and written quote.
Why Winslow Windows & Doors Is Greenacres’s Preferred Impact Windows Company
Ed Winslow founded this company in 2011, and his name is on the door, on the trucks, and on every job we do. We’re not a franchise operation with a rotating cast of subcontractors. The same crew that measures your Greenacres home is the crew that installs your windows. We know the difference between a home off Jog Road and one off Lake Worth Road, because we’ve been inside hundreds of both.
Greenacres homeowners call us for a few reasons. We answer the phone 24 hours a day with a live person, not a voicemail tree. Our technicians are background-checked and arrive in uniform, so you know exactly who’s at your door before the truck pulls up. And our Done Right Promise is simple: if it’s not done right, we make it right. No fine print, no expiration. A neighbor you can call at 2 a.m. and someone will actually answer.
Every window and door replacement in Greenacres requires a Palm Beach County permit, and we pull that permit on every job. We don’t ask you to navigate the county process. We handle the paperwork, schedule the inspection, and make sure every opening meets the 140-150 mph design wind speeds that apply to inland Palm Beach County locations like Greenacres.
Our Impact Windows Services in Greenacres
Impact-Rated Window Replacement
Most Greenacres homes we visit still have the original aluminum single-pane windows installed during the western Palm Beach County building boom of the 1970s and 1980s. Rubber glazing seals crack under the intense UV exposure we get here, frames corrode, and the units fail wind mitigation inspections. We replace them with impact-rated units sized to your existing openings or reframed to new rough openings when the old jalousie left something non-standard. A typical impact window replacement in Greenacres runs $800-$1,500 per window installed, depending on opening size and frame material.

Impact Sliding Glass Doors
Original aluminum sliding glass doors on Greenacres CBS homes flex under design pressures of up to 150 mph. That flex misaligns sash tracks, wears out rollers, and compromises the large-missile rating the opening needs to protect your home. We install impact-rated sliders with laminated glass and reinforced frames that meet Miami-Dade NOA standards. Impact sliding glass door replacement in Greenacres typically runs $2,500-$5,000 per opening, varying by width and track configuration.

Custom Jalousie-to-Impact Conversions
This is the signature Greenacres job. Hundreds of homes here still carry the original aluminum jalousie windows, and there’s no retrofit path for those multi-louver units. You can’t add film, you can’t add clips, you can’t bolt on shutters over a louvered frame. The opening has to come out and get reframed for a real impact-rated window. We handle that reframing in-house, which matters because jalousie rough openings are wider and shallower than modern window standards. Conversion work on a Greenacres rancher off Jog or Haverhill typically adds $100-$200 per opening in reframing labor and materials on top of the window cost.

Energy-Efficient Impact Window Upgrades
Impact windows don’t just protect against wind-borne debris. They also replace those air-leaking jalousie and single-pane aluminum units with insulated laminated glass. Greenacres cooling loads run high from May through October, and sealed impact units reduce the air leakage that drives your AC to run long cycles. We install impact windows with Low-E coatings and argon gas fills that meet Florida’s energy code while carrying the structural ratings your wind zone requires.

Trusted Brands We Service in Greenacres
Our Impact Windows team installs products from authorized manufacturers including CGI, ES Windows, and ECO Window Systems. These aren’t generic import frames from a big-box shelf; each configuration carries its own Florida Product Approval and Miami-Dade NOA numbers, which means the window or door you buy in Greenacres is code-compliant for Palm Beach County’s wind-borne debris region. We order directly from the manufacturers, so when you need a custom size or a specific finish, there’s no middleman guessing at lead times. Custom fabrication typically runs 4-6 weeks, and installed in as fast as a single day once your units arrive.
Common Impact Windows Problems We See in Greenacres Homes
- Corroded aluminum jalousie frames. Salt air doesn’t stop at the Intracoastal. In Greenacres, the prevailing onshore breeze carries enough marine air inland to accelerate corrosion on 40-year-old aluminum window frames. We regularly see jalousie frames so pitted and seized that the louvers won’t close tight, which means they never sealed against water or wind anyway.
- Failed glazing seals and fogged glass. The rubber seals on 1970s and 1980s single-pane aluminum windows dry out and crack under the sun we get in Greenacres. Once that seal fails, you get air leaks, water intrusion, and condensation between panes on any double-pane replacements somebody installed along the way. A failed seal is an automatic fail on a wind mitigation inspection.
- Flexing, misaligned sliding glass doors. Non-impact sliders installed during original construction were never tested against 150 mph design wind pressures. After decades of storm cycles and thermal expansion, the frames rack, the sashes drag, and the rollers chew up the bottom track. That’s the opening most likely to fail during the next storm to track across Palm Beach County.
- Insurance four-point inspection flags. Greenacres homeowners get flagged when the inspector finds jalousies, non-impact glazing, or single-pane sliding glass doors without the proper product approval labels. Once flagged, many insurers give you 30-60 days to replace the opening or face non-renewal. We see this weekly across Greenacres neighborhoods from Pine Ridge to Chariot Trace.
Pricing for Impact Windows in Greenacres, FL
Impact windows generally run $800-$1,500 per window installed in Greenacres. Impact single-hung windows fall in the $900-$1,800 range depending on size and frame material. Large or custom openings - picture windows, geometric units, oversized sliders - run $2,500-$5,000 each. Whole-home packages for a typical 3-bedroom CBS ranch in Greenacres usually land between $8,000 and $25,000 and up, depending on the number of openings and how many jalousie conversions the job requires.
What actually moves the number: how many openings, whether they’re standard or jalousie-sized, which wind zone applies to your lot (design pressures increase with exposure), and whether you choose aluminum, vinyl, or impact-rated wood frames. We give you a written line-item quote before any work begins, and that quote doesn’t change unless you change the scope. Upfront pricing. No surprises on the invoice.
What Impact Windows Costs in Greenacres
Here’s the honest math for Greenacres specifically. Because most homes here are from the 1970s and 1980s with non-standard jalousie openings, you should expect slightly higher labor and reframing costs than a newer subdivision with modern rough openings. A straightforward single-hung replacement lands around $900-$1,200. A jalousie-to-impact conversion with reframing typically runs $1,100-$1,600 per opening. Full sliding glass door replacements start around $2,800 and rise with width and frame finish.
We also install large custom openings - picture windows, radius units, and geometric shapes - and those hold the $2,500-$5,000 range. If you want a whole-home package, we’ll walk the house with you, measure every opening, and produce a single written quote with line items for each unit. Call (561) 782-7525 to schedule a free in-home measure and written quote. No obligation, and the quote is yours to compare.
Florida Pays You Back
Greenacres homeowners have access to several incentive programs that offset the cost of impact windows and doors. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, which includes impact-rated window and door replacements. Florida exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit can return 30% of the product cost, up to $600 per year, on qualifying energy-efficient units. And after you complete a wind-mitigation inspection (typically $75-$150 in Palm Beach County), many homeowners see windstorm premium reductions averaging around 25% on the windstorm portion of their policy. We don’t guarantee those numbers - your carrier sets the final figure - but the inspection we recommend as part of your replacement gives you the documentation to ask.
One comparison worth making: impact windows versus hurricane shutters. Shutters are panels you store, haul out, and hang before every storm. Impact windows are permanent protection built into the structure. In Greenacres, where the code already requires impact-rated openings for most replacements, choosing shutters over impact windows usually means you’re still replacing the old window underneath - you’re just adding more hardware on top of a failing unit. Impact windows solve the protection, the energy loss, and the insurance flag in one decision.

FAQs - Impact Windows in Greenacres
Yes. Greenacres sits within Palm Beach County’s wind-borne debris region, and any window or door replacement requires a permit and must meet impact-resistance standards for the home’s design wind pressures, which in Greenacres run in the 140-150 mph range for inland locations. A non-impact replacement would fail a structural and wind-load inspection. Call (561) 782-7525 for a free estimate and we’ll confirm what your specific opening requires.
No. Jalousie windows cannot be retrofitted to meet any impact standard because their multi-louvered design doesn’t accept laminated glass or pressure-rated frames. The entire unit must be removed and the opening reframed for a standard impact-rated window. That’s the jalousie-to-impact conversion we handle regularly on Greenacres homes, and it usually adds $100-$200 per opening in reframing work. For exact numbers on your home, call us at (561) 782-7525.
Yes, and the difference is measurable. Original jalousie and single-pane aluminum windows leak air constantly, and in Greenacres’s hot, humid climate that leaked air carries moisture your AC has to remove along with heat. Impact windows with Low-E laminated glass and tight compression seals eliminate that leakage, which lowers cooling load and evens out room temperatures. Many Greenacres customers report quieter, more comfortable homes within days of replacement. Want to see the math for your house? Call (561) 782-7525 for a free in-home measure.
In Greenacres, impact windows remove the openings your four-point inspection flags as non-compliant, which makes the home insurable or prevents a non-renewal. After installation and a wind-mitigation inspection, many Palm Beach County homeowners see windstorm premium reductions averaging around 25% on the windstorm portion of their policy. The product approval numbers on your new windows are the documentation your agent needs. Call (561) 782-7525 for a free estimate - we’ll walk you through the inspection process.
We install impact windows and doors from CGI, ES Windows, and ECO Window Systems, along with several other authorized lines including PGT and CWS.
