Fast, Reliable Window Installation Across Greenacres
Window installation in Greenacres runs $800 to $1,800 per opening for impact-rated units, with whole-home projects typically landing between $8,000 and $25,000 depending on how many openings your house has and what’s being torn out. If you own a concrete block home built between the late 1960s and early 1990s, you’re probably looking at full-frame replacement rather than pocket inserts, because the original aluminum frames have been eaten alive by decades of humidity. That’s the reality of the housing stock here, and it’s why our crews know Greenacres addresses before they ever ring the bell. Call (561) 468-6136 and Ed Winslow’s team will walk you through exactly what your house needs, what it costs, and what the permit requires.

Why Winslow Windows & Doors Is Greenacres’s Preferred Window Installation Company
Ed Winslow has been putting his name on windows, doors, and roofs since 2011, and that name carries weight in Palm Beach County. We’re not a national chain with a rotating cast of installers. Every technician who shows up at a Greenacres home is background-checked, uniformed, and accountable to the same person whose name is on the truck. That’s a different relationship than you get when a big-box retailer subcontracts your window job to the lowest bidder.
We answer the phone 24 hours a day, seven days a week. Not a call center, not a voicemail loop. A live person. When a Greenacres homeowner calls at 9 p.m. worried about a failed window seal before hurricane season, they talk to someone who can actually give them answers. And because we’re authorized installers for PGT, CGI, CWS, among others, we’re not guessing at product specs. We know what Palm Beach County plan review will accept, which means your permit doesn’t stall.
Our reputation in Greenacres is built on jobs done right the first pass. Homeowners off Jog Road, near Samuel J. Ferreri Community Park, and throughout the neighborhoods around Lake Worth Road call us back when it’s time for the next phase. That repeat business is the review that matters most to us.
Our Window Installation Services in Greenacres
Single & Double Hung Windows
The workhorse of Palm Beach County bedrooms and living rooms. In Greenacres’s CBS tract homes, single and double hung units are the most common upgrade from failed single-pane sliders. We install them as full-frame replacements, which means pulling the old corroded aluminum frame out to the block and setting a properly flashed, properly sealed impact-rated unit in its place. A typical double hung in this market runs $900 to $1,800 installed, depending on opening size and which manufacturer you choose.

Horizontal Roller Windows
Horizontal rollers are everywhere in Greenacres because they were standard issue on 1970s and 1980s tract builds. The problem is the originals were single-pane, non-impact, and aluminum. Four decades of Florida sun and humidity have pitted the frames and destroyed the glazing seals. We replace them with impact-rated horizontal rollers carrying Florida Product Approval, sized to match the opening but now meeting current wind-load code. That’s a conversation most homeowners have never had before we show up.

3-Panel Sliding (3-Lite Roller) Windows
Common on the wider wall spans in Greenacres living rooms and Florida rooms. Three-panel sliders are a big opening, and big openings need careful engineering. We match design pressures to the specific wall, the floor height, and the wind zone Greenacres falls under. A 3-lite roller replacement typically runs $2,500 to $5,000 installed for the full assembly, and it’s a job where doing it wrong means a leak you won’t see until the wall is wet.

Casement Windows
Casements give you full ventilation and a tighter seal than sliders, which matters in a climate where the air conditioner runs ten months a year. We see them most often in Greenacres kitchens and bathrooms, where homeowners want better airflow without losing the impact rating. Casements are also the easiest style to make compliant on medium openings, since the crank mechanism compresses the sash against the frame with more force than a sliding unit can manage.

Common Window Installation Problems We See in Greenacres Homes
- Non-impact windows sold as “hurricane rated.” Greenacres falls inside Palm Beach County’s wind-borne debris region, which means every replacement window must carry Florida Product Approval for impact resistance. Windows that don’t are unpermittable here, plain and simple. If a quote doesn’t mention FL approvals, walk away.
- Pocket inserts shoved into corroded aluminum frames. On most of the 1968-1992 CBS stock across Greenacres, the original frames are too far gone to hold a new insert properly. The frame has to come out to the block, or the new window won’t seal and won’t meet design pressure. We see it constantly from companies that won’t do full tear-out.
- Jalousie windows left in place during a “whole-house” replacement. Those louvered glass panels on a 1970s bathroom or utility room are functionally impossible to bring up to code. Palm Beach County will not permit them as-is. Every jalousie has to come out and be replaced with an impact-rated unit. If a contractor tells you otherwise, they haven’t pulled permits before.
- South-facing windows chalking and pitting within a decade. The UV index in Greenacres is brutal on vinyl and aluminum alike, especially on south and west elevations. We spec frame materials and glass coatings with that reality in mind, because the wrong choice means a chalk-forward, faded frame by year eight.
Pricing for Window Installation in Greenacres, FL
A single impact-rated window in Greenacres starts around $800 and runs up to $1,800 for a standard double hung, installed. A large custom opening, like a big picture window or a three-panel slider, lands between $2,500 and $5,000. Whole-home packages on the typical three- to four-bedroom CBS house here run $8,000 to $25,000 and up, depending on opening count, frame material, glass package, and whether there are jalousies to remove. We don’t give ballparks over the phone and then change the number once we see the house. We measure, we spec, we write the quote, and we sign it.
What Window Installation Costs in Greenacres
Let’s be specific. In Greenacres today, you should expect to pay $800 to $1,500 per opening for standard impact windows installed. A quality impact single-hung runs $900 to $1,800. Large or custom openings, like a 3-lite roller spanning a living room wall, go $2,500 to $5,000. A whole-home package on a typical Greenacres CBS home lands between $8,000 and $25,000. What moves the price: how many openings you have, whether jalousies need full conversion, floor height (second-story work costs more), and which frame material you pick. Vinyl is the most common choice here; reinforced vinyl and aluminum are options for larger spans. The free in-home measure and written quote is how this should work, and it’s how we do it.

Florida Pays You Back
There’s real money on the table for Greenacres homeowners, and most people never hear about all three stacks. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, which impact windows absolutely count toward. Florida’s sales-tax exemption applies to impact-resistant windows and doors, so you’re not paying sales tax on the units themselves. And the federal 25C energy credit covers 30% of the product cost for qualifying energy-efficient units, up to $600 per year. Beyond that, most windstorm carriers apply a premium credit averaging around 25% on the windstorm portion after a wind-mitigation inspection, which runs $75 to $150. We can’t guarantee what your carrier will do, but we can make sure the documentation from our install supports the inspection. Call (561) 468-6136 to talk through what applies to your house.

FAQs - Window Installation in Greenacres
In Greenacres you need Florida Product Approval (FL#) for impact resistance. The stricter Miami-Dade Notice of Acceptance (NOA) rating is required one county south in Broward and Miami-Dade, which sit inside the High Velocity Hurricane Zone. Greenacres is in Palm Beach County’s wind-borne debris region but outside the HVHZ, so FL-approved units close the permit and satisfy code. Miami-Dade NOA products cost more because they meet a higher bar you’re not required to meet. Call (561) 468-6136 and we’ll spec the right rating for your opening, no upsell.
No. Jalousie windows, the louvered glass units common on 1970s and 1980s Greenacres homes, cannot be permitted under current Palm Beach County code. They have to come out completely and be replaced with an impact-rated unit. If a contractor quotes a “whole-house” job and doesn’t mention the jalousies, they haven’t looked at the permit requirements. Call (561) 468-6136 for a quote that accounts for every opening, not the ones that are easy.
Because the original aluminum frames in the 1968-1992 concrete block houses across Greenacres are corroded from decades of South Florida humidity. Inserting a new window into a frame that’s already failing means the new unit can’t seal properly and won’t hold design pressure rating. Full-frame tear-out to the block is the standard job here, and it’s what we do on nearly every home in the city. The cheaper quote that skips tear-out is a leak waiting to happen. Call (561) 468-6136 for an honest assessment of your frames.
Most windstorm carriers in Palm Beach County apply a premium credit after you complete a wind-mitigation inspection, which runs $75 to $150. The credit on the windstorm portion of your premium averages around 25%, but the final number depends on your carrier and your specific home’s construction. We document every install with the ratings and approvals your inspector needs to see. Call (561) 468-6136 and we’ll walk you through what to ask your agent.
Replacement windows in Greenacres must meet the design wind speeds set by the Florida Building Code for Palm Beach County’s wind-borne debris region, which vary by floor height and wall location. The units we install carry Florida Product Approval with large-missile impact ratings, and we size design pressures to each specific opening rather than applying a blanket number. Call (561) 468-6136 and we’ll show you the ratings on the exact units we’re quoting for your house.
The One Thing You Need to Know About Greenacres Window Permits
Greenacres sits in Palm Beach County’s wind-borne debris region but outside the High Velocity Hurricane Zone, which changes everything about what windows you’re allowed to install and what you’ll pay for them. Replacement windows here require Florida Product Approval (FL#) for impact resistance. They do not require the Miami-Dade Notice of Acceptance (NOA) products mandated just one county south. That’s not a small distinction. NOA-rated units carry a premium you don’t need to pay in Greenacres. A contractor who quotes you Miami-Dade windows without explaining this is either confused or padding the invoice. We spec FL-approved units, we close the permit, and we pass the savings to you.
A field story, in our own words: On a 1970s CBS home off Sherwood Forest Blvd, our crew tore out corroded original jalousie and single-pane aluminum sliders, replacing every opening with PGT WinGuard impact-rated insulated glass units carrying Florida Product Approval. The homeowner was shocked to learn the jalousies in the utility room and Florida room were unpermittable as-is. We removed them completely and installed double-hung and horizontal roller units that met the large-missile rating and closed the permit without a hitch. That is what a compliant quote looks like in Greenacres.
One more thing worth knowing: impact windows beat hurricane shutters for permanent protection. Shutters mean panels you have to haul out and hang before every storm, and if you’re not home when the warning goes up, your openings are unprotected. Impact windows are always in place. They’re also a selling point when you list the house, because the next buyer inherits the rating and the insurance credit. A big-box retail quote for shutters might look cheaper on paper. It’s not cheaper when you factor in the labor of hanging them, the storage, and the fact that they do nothing for energy efficiency the other eleven months of the year.
