Fast, Reliable Window Installation Across Greenacres
Window installation in Greenacres usually runs $800-$1,500 per impact-rated unit installed, with whole-home packages starting around $8,000. Most of the work we do here is insurance-driven replacement on pre-1992 concrete block homes, and we schedule free in-home measures across every Greenacres neighborhood within a few days of your call. If you’re staring at a non-renewal notice or an open permit, call (561) 816-5648 and Ed Winslow will pick up.
We’ve worked on more of Greenacres’s CBS homes than we can count, and we know what Palm Beach County’s building department will flag before we ever load a window on the truck. That’s the difference between a job that passes inspection the first time and one that leaves your opening boarded up during hurricane season. Our Window Installation team handles everything from single openings to full-home insurance retrofits, and we answer the phone like a neighbor because that’s what we are.
Why Winslow Windows & Doors Is Greenacres’s Preferred Window Installation Company
Ed Winslow founded this company in 2011, and his name is still on the door. We’re locally owned and owner-operated, with a published address and license number. When you call Greenacres, you talk to a real person, not a call center routing you to a ticket queue. That matters when an inspector red-tags a rough-in and you need answers at 6 p.m.
Our Greenacres customers consistently tell us the same two things: the crew showed up in uniform, background-checked and ready, and the final invoice matched the written quote. No change orders, no surprise line items, no “we’ll get back to you on that.” Every technician who steps onto a Greenacres driveway works for Ed, not a subcontractor we’ve never met.
We carry the 36500-Day Done Right Promise on every installation. If it’s not done right, we make it right. That’s a century-long standard of accountability, and it’s why Greenacres homeowners who’ve been burned by vague estimates call us when the insurance letter arrives.
Our Window Installation Services in Greenacres
Horizontal Roller Windows
Horizontal rollers are the natural replacement for the original single-pane aluminum sliders in Greenacres’s 1970s-1990s CBS homes. The opening widths in these houses are oversized by modern impact-product standards, so we backer-frame each rough opening before setting the unit. That’s the only way the jamb alignment and design pressure rating stay intact. In Greenacres, horizontal rollers are often the most cost-effective way to get large-missile rated glass into a pre-1992 living room without changing the architectural look.

3-Panel Sliding (3-Lite Roller) Windows
If your Greenacres home has a wide lanai wall or a picture opening that faces the street, our Sliding Glass & Patio Doors in Greenacres are usually the cleanest impact solution. These units carry Florida Product Approval and large-missile ratings matched to the opening’s design pressure. We order each configuration custom-fabricated to the exact rough opening dimensions, because nothing off the shelf fits a 1985 CBS opening correctly. Lead time runs 4-6 weeks on custom fabrication, and we lock the price in writing before we order anything.

Casement Windows
Casement windows give Greenacres homeowners the tightest seal against wind-driven rain, which matters when a summer squall line pushes 50 mph gusts across the neighborhood. They’re also a smart choice for openings that face prevailing winds from the southeast. We install casements with multi-point locking hardware and laminated impact glass, and the crank operation makes them practical for hard-to-reach spots like over a kitchen sink.

Single & Double Hung Windows
For Greenacres homes where the original aluminum single-hungs are still in place, single and double hung impact windows preserve the vertical-slide look while meeting Florida’s current wind-load codes. These are popular on the front elevations of homes in the Sherwood Lakes and Nautica Lakes neighborhoods. We install both styles with low-E insulated glass so you get the hurricane protection and a real drop in afternoon cooling load with Energy-Efficient Windows in Greenacres.

Trusted Brands We Service in Greenacres
We’re an authorized installer for PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. For Greenacres’s pre-1992 openings, we lean on PGT and ECO Window Systems for impact horizontals and casements, and we often recommend Mr-Glass for custom sizes when backer-framing would change the sightlines too much. Because we work with these brands daily, we can give Greenacres customers real availability windows and honest lead times instead of a guess. We also keep a running stock of common frame extrusions and hardware in South Florida, which helps us turn around warranty service faster than a chain that’s waiting on a warehouse in another state.
Common Window Installation Problems We See in Greenacres Homes
- Skipping the rough-in inspection. Palm Beach County requires a separate inspection before any glazing or door unit gets set in the opening. Crews that skip this step get red-tagged, leaving a Greenacres home with open or boarded openings during an active Atlantic hurricane season. We schedule the inspection before we remove the old windows, not after.
- Ordering off-the-shelf impact windows for oversized pre-1992 CBS openings. The original single-pane aluminum units in Greenacres’s concrete block homes were frequently wider and taller than what modern impact products are fabricated to fit. Forcing an off-the-shelf unit into an oversized rough opening compromises the design pressure rating. We measure every opening twice and backer-frame to exact dimensions.
- Using non-rated or panel-protected-only products to save money. Greenacres sits 7-10 miles inland, outside the High Velocity Hurricane Zone, so Miami-Dade NOA approval isn’t strictly required here. But design wind speeds in this part of Palm Beach County still exceed 140 mph, and insurers are asking for Florida Product Approval with large-missile ratings. Cheaper non-rated glass often gets the wind-mitigation discount rejected after the first inspection.
- Ignoring the two-stage permit sequence. Out-of-county crews routinely underestimate Palm Beach County’s permit process for window and door replacements. The rough-in inspection is a separate stop before the units get set, and if it’s not on the calendar from day one, the whole project stalls. We’ve pulled enough permits in Greenacres to know the sequence by heart.
What Window Installation Costs in Greenacres
Here’s what Greenacres homeowners can expect as of mid-2025, based on our recent work across the city:
| Product | Typical Installed Price (Greenacres) |
|---|---|
| Impact window (standard size) | $800-$1,500 per window |
| Impact single-hung | $900-$1,800 per window |
| Large or custom opening (backer-framed) | $2,500-$5,000 per opening |
| Whole-home package (8-12 openings) | $8,000-$25,000+ |
What moves the price in Greenacres is the opening count, the wind-zone engineering on each elevation, floor height, and whether the frame requires backer-framing to bring the rough opening down to code-compliant dimensions. The more oversized the original aluminum slider, the more carpentry and custom-order work goes into the replacement. We give every Greenacres customer a written, line-item quote after a free in-home measure. That quote is the price. It doesn’t change once we start, unless you change the scope.

Why Greenacres’s Pre-1992 CBS Stock Needs a Different Installation Template
Over 60 percent of Greenacres homes are pre-Hurricane-Andrew concrete block houses from the 1970s through early 1990s, and their original single-pane aluminum windows fail Florida’s current wind-load and large-missile standards outright. That makes insurance-mandated impact window replacement the single largest driver of Window Installation work here. It’s a sharp contrast to younger Palm Beach County suburbs like Wellington, where code-compliant windows were installed from the start and the retrofit market is nearly nonexistent.
What that means practically: Greenacres’s original window openings are oversized by modern impact-product standards. The jambs don’t align without backer-framing. The rough openings need to be measured, re-framed to exact dimensions, and inspected before any new unit is set. And because Palm Beach County’s building department requires a separate rough-in inspection before glazing, the sequence on a Greenacres retrofit is: remove, frame, inspect, set, final inspect. Skipping step three is how homes end up boarded for days in August.
Greenacres also sits roughly 7-10 miles inland from the Atlantic, outside the High Velocity Hurricane Zone that governs Miami-Dade and Broward counties. That means replacement windows and doors must carry Florida Product Approval but do not strictly require the more rigorous Miami-Dade Notice of Acceptance. Still, the design wind speeds for this part of Palm Beach County routinely exceed 140 mph, so only rated impact or panel-protected products are practical for insurability. This is the exact knowledge that keeps a Greenacres retrofit from turning into a red-tag nightmare.
A Greenacres Field Note
We recently replaced a full set of original single-pane aluminum sliders on a 1982 CBS home in the Sherwood Lakes neighborhood with PGT 770 Vinyl Impact Horizontal Rollers carrying Florida Product Approval and large-missile rating. The existing openings were oversized by modern impact-product standards, so we backer-framed each opening to the correct rough dimension, scheduled Palm Beach County’s separate rough-in inspection before setting the units, and then installed insulated glass units with laminated glass interlayers and low-E coating to meet the insurer’s wind mitigation requirements. The whole job took the same calendar time as a standard install, but only because the inspection was on the books before we removed the first frame.
That’s the difference between an installer who works in Greenacres regularly and one who’s guessing. We know which neighborhoods in the 33415 and 33463 ZIP codes have the widest original openings, and we know which inspectors want to see the backer-framing before they’ll sign off. That local knowledge is built into every quote we write.
Pricing for Window Installation in Greenacres, FL
A single impact window in Greenacres runs $800-$1,500 installed, with single-hungs at $900-$1,800. Custom or oversized openings, which are common in the pre-1992 CBS stock here, land at $2,500-$5,000 per opening. Whole-home packages on a typical Greenacres 3/2 concrete block house run $8,000-$25,000 depending on opening count and frame work.
Greenacres’s two-stage inspection adds a line item that out-of-county crews often forget to include, and backer-framing oversized openings adds labor and material compared to a like-for-like swap in a newer home. Our quotes fold both in from the start. Free in-home measure, written quote, fixed price. Call (561) 816-5648 to book yours.
Florida Pays You Back
Greenacres homeowners can stack several incentives on impact window installations. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and some Greenacres households qualify based on income and home value. Florida also exempts impact-resistant windows and doors from sales tax, which shaves 6-7% off the product cost at purchase. The federal 25C energy credit returns 30% of the product cost, up to $600 per year, on qualifying insulated glass units.
On the insurance side, a wind-mitigation inspection (typically $75-$150 in Palm Beach County) can unlock windstorm-premium credits averaging around 25% on the windstorm portion after impact windows are installed and documented. No guarantees, because programs and carriers set their own final numbers, but these are the levers Greenacres homeowners actually pull after we finish an install. We’ll point you to the right forms and inspectors; we just don’t file the claims for you.
One thing we tell every Greenacres customer weighing impact windows against hurricane shutters: shutters only protect the opening when someone is home to close them, and they do nothing for a window’s thermal performance or noise. Impact windows are permanent, rated protection that works whether or not you’re there. If a storm spins up while you’re out of town, the glass we installed already passed its large-missile test. Shutters are still sitting in the garage.

FAQs - Window Installation in Greenacres
Palm Beach County requires a separate rough-in inspection so the building department can verify the opening dimensions, backer-framing, and anchoring before any glazing or our Door Installation in Greenacres gets set. This two-stage permit sequence exists because once a unit is glazed into the opening, inspectors can’t see what’s behind the frame. In Greenacres, where most homes have pre-1992 oversized openings, the rough-in inspection is where backer-framing and jamb alignment get signed off. Skipping it gets you red-tagged, and the opening stays open or boarded until it’s resolved. Call (561) 816-5648 for an exact quote; we schedule your rough-in inspection before we remove the first window.
Greenacres windows only need Florida Product Approval, not Miami-Dade NOA. The city sits 7-10 miles inland, outside the High Velocity Hurricane Zone, so the stricter Miami-Dade notice of acceptance isn’t required here. However, design wind speeds in this part of Palm Beach County still exceed 140 mph, so your windows must carry Florida Product Approval with a large-missile rating to satisfy most insurers. We’ll match each opening’s design pressure to the right product and document it for your wind mitigation file. Call (561) 816-5648 for a free measure and we’ll show you the product approvals for your specific openings.
You can qualify for a wind-mitigation discount by installing impact-rated windows on every opening in your Greenacres home and then passing a wind-mitigation inspection. The discount averages around 25% on the windstorm portion of your premium, but your carrier sets the exact number. The inspector will verify that every window carries a Florida Product Approval number with a large-missile rating and that the installation matches the product’s design pressure. We document all of that for every install we do in Greenacres. Call (561) 816-5648 to talk through what your insurer will need.
Horizontal roller and 3-panel sliding windows work best for the oversized openings common in Greenacres’s pre-1992 concrete block homes, because they can be fabricated in wide custom widths that preserve the original sightlines. Casement windows are also a strong choice where the opening is tall and narrow or faces southeast. The key is backer-framing the rough opening to exact dimensions before setting any unit, which we do on every Greenacres retrofit. Call (561) 816-5648 and we’ll tell you which style fits your specific openings after a free measure.
Impact windows with low-E glass cut cooling costs in Greenacres by reducing solar heat gain through the glass, which matters when your AC runs from April through October. The low-E coating blocks a meaningful portion of the infrared energy that heats up a concrete block home’s interior, and the insulated glass unit slows conductive heat transfer compared to the original single-pane aluminum. Most Greenacres homeowners see a noticeable drop in afternoon indoor temperature after a full impact retrofit. Call (561) 816-5648 and we’ll quote you the exact glass packages available for your openings.
