Fast, Reliable Sliding Glass & Patio Doors Across Greenacres
Replacing a sliding glass or patio door in Greenacres usually means more than swapping out an old aluminum frame. Most homes here were built between 1965 and 1995, and the original single-pane sliders have spent decades fighting Palm Beach County humidity, salt air, and hurricane seasons. We’re Winslow Windows & Doors, and we’ve been working on those exact doors since 2011. Ed Winslow’s name is on the business, and his standard is on every install we do: if it’s not done right, we make it right. Call (561) 660-9539 and a live person answers, day or night.
Why Winslow Windows & Doors Is Greenacres’s Preferred Sliding Glass & Patio Doors Company
Greenacres homeowners call us because we understand what their houses actually are: compact CBS ranch-style homes, mostly 1,100 to 1,800 square feet, built fast and affordably for workforce families. Those homes have specific problems. Original aluminum sliders corrode at the jambs, bind on the track, and leak wind-driven rain into drywall. Jalousie windows flanking old patio doors create wind-mitigation dead zones. We see these failures every week in Greenacres, and we scope every job with the county’s wind-load standards in mind, not just the product catalog.
Our Sliding Glass & Patio Doors team is background-checked and arrives in uniform, so you know exactly who’s at your door before the truck pulls up. We install PGT, CGI, Therma-Tru, and other authorized brands, and we pull the Florida Product Approval documentation for every opening before we quote. That matters in Greenacres, where Citizens Insurance and private carriers are pushing wind-mitigation inspections hard. A door that doesn’t document cleanly can cost you thousands in premiums.
We coordinate dispatch and scheduling from our South Florida office, and crews serve Greenacres locally. The people measuring your openings, ordering your units, and running your install know the difference between a Sherwood Forest CBS ranch and a newer Wellington stucco build. That local knowledge is the difference between a quote that holds and a quote that falls apart on install day.
Our Sliding Glass & Patio Doors Services in Greenacres
Impact-Rated Sliding Glass Door Replacement
Greenacres sits roughly 12 to 15 miles inland from the Atlantic, inside Palm Beach County’s high-wind design zone. Your original aluminum sliders were never rated for the ~140 mph wind speeds your home faces. We replace them with impact-rated units carrying Florida Product Approval numbers and large-missile ratings matched to the opening. Every install includes proper flashing on the low-slab CBS walls that dominate Greenacres, because wind-driven rain at the track is the failure point we see most often when old doors come out.

Jalousie-to-Impact Conversions Paired with Patio Door Upgrades
This is the job Greenacres is known for. Pre-1980 homes here were built with jalousie or louvered windows that cannot be retrofitted to any recognized impact rating. Every wind-mitigation inspection flags them as full replacements. Here’s the part most homeowners don’t know until inspection day: you cannot get wind-mitigation credits for a new impact slider if jalousie windows remain on the same structure. The inspector will not partially credit a home. So in Greenacres, a patio door replacement frequently becomes a whole-house conversion, and we scope it that way from the first visit.

Wind-Mitigation Inspection Prep and Documentation
After we install impact doors and windows in Greenacres, we provide the documentation your wind-mitigation inspector needs: Florida Product Approval numbers, design pressure ratings, and installation details for every opening. We don’t leave you to sort through paperwork. Ed Winslow has watched too many Greenacres homeowners lose premium credits because a contractor didn’t supply the right docs. We make sure the inspector has what they need before they arrive.

Sliding Glass Door Repair and Track Replacement
Not every Greenacres slider needs a full replacement. If the glass is intact but the rollers are shot, the track is corroded, or the jamb has pulled loose, we repair what’s salvageable. We’ll tell you honestly if a repair will buy you three more years or if the door is beyond saving. A $40 discount applies to any repair over $200, and we offer free second opinions on any written estimate you’ve received from another company.

Trusted Brands We Service in Greenacres
We’re an authorized installer for eight premium manufacturers, and for Greenacres homes we most often spec PGT and CGI for impact-rated sliders, with Therma-Tru for entry and patio door combinations. ES Windows and ECO Window Systems come into play for larger openings and custom sightlines. We stock common parts locally and coordinate direct-to-site delivery from our West Palm Beach yard, which keeps narrow Greenacres streets clear of staging delays. If you already have a brand in mind, call (561) 660-9539 and we’ll tell you whether it fits your opening and your wind zone.
Common Sliding Glass & Patio Doors Problems We See in Greenacres Homes
- Corroded aluminum jambs and sashes. Decades of humid, salt-laden air from the coast eats aluminum frames from the inside out. Doors bind, stick, and eventually fail simple racking tests, which is exactly what a wind-mitigation inspector checks first.
- Jalousie windows flanking the patio door. You can’t secure one opening while leaving louvered panels unrated next to it. Inspectors will not grant partial credit, which is why so many Greenacres door replacements become whole-house conversions.
- Water intrusion at the track on low-slab CBS homes. Improperly flashed sliders allow wind-driven rain to wick into interior drywall. The mold hides along the track and only shows up when the door is removed. We see this constantly in Greenacres when pulling old doors.
- Worn rollers and bent tracks from decades of use. Original sliders on 1970s and 1980s builds weren’t designed for daily use over 40-plus years. Rollers flatten, tracks bend, and the door becomes a two-person job to open.
Pricing for Sliding Glass & Patio Doors in Greenacres, FL
A standard impact-rated sliding glass door replacement in Greenacres typically runs $2,800 to $4,800 installed, depending on opening width, frame material, and the design pressure rating your home requires. If the job bundles with a jalousie-to-impact conversion, which is common here, a full-house project on a 1,200 to 1,500 square foot CBS ranch usually lands between $14,000 and $28,000. Larger custom openings, multi-panel sliders, and doors with matching side lites push toward $5,000 to $8,000. The variables that move the price in Greenacres are opening count, wind zone requirements, floor height, and whether your existing rough opening needs reframing. We provide a written line-item quote after a free in-home measure, and the price we quote is the price you pay. Call (561) 660-9539 to schedule yours.
What Sliding Glass & Patio Doors Costs in Greenacres
Here’s the honest range, based on what we quote daily in Greenacres. Impact-rated sliding glass doors generally run $800 to $1,500 per unit for the door itself, with installation bringing the total to $2,800 to $4,800 per opening. A single-hung impact window alongside your new slider adds $900 to $1,800 per unit. Large or custom openings, like a 12-foot multi-panel slider on a lakefront lot, run $2,500 to $5,000 or more. Whole-home packages that include impact sliders and full jalousie-to-impact window replacement in Greenacres start around $8,000 and frequently reach $25,000 to $35,000 on larger homes with multiple openings. What moves the price: the number of openings, the design pressure rating your specific wall requires, floor height, and whether we’re reframing any rough openings. We measure everything in person and give you a written quote before any work starts.
Florida Pays You Back
Greenacres homeowners have real incentives available, and we’ll walk you through every one. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, which frequently cover impact doors and windows. Florida also exempts impact-resistant windows and doors from sales tax. At the federal level, the 25C energy credit can return 30% of product cost, up to $600 per year, on qualifying energy-efficient units. After a wind-mitigation inspection, which typically runs $75 to $150, most Greenacres homeowners see windstorm premium credits averaging around 25% on the windstorm portion of their policy. Programs and carriers set the final numbers, not us. But we document every opening so you can claim what you’re owed. One more thing worth knowing: permanent impact protection beats hanging shutters every hurricane season. No panels to wrestle, no storage, no 2 a.m. scramble when a watch gets upgraded. And unlike a big-box retail install, every unit we place carries a Florida Product Approval number matched to the opening’s design pressure, never above +/-100.
Building on Acreage Around Greenacres
Greenacres has grown outward into unincorporated Palm Beach County, which means a meaningful share of our sliding glass and patio door work happens on acreage lots with different rules than a standard city lot. County permitting, not city permitting, governs the job. Septic and well setbacks can dictate where a patio door can face, which changes the rough opening location before we even order glass. Long material hauls and equipment access matter on dirt drives and narrow right-of-ways, and we stage deliveries carefully so a semi doesn’t get stuck turning around. Outbuildings, detached shops, and ADUs often have their own sliders that need impact rating too, and we scope those separately. Grading and drainage on an open lot affect how water moves around the slab, which changes how we detail flashing at the threshold. We walk every acreage site before quoting, because a door on a half-acre in the county is not the same job as a door on a zero-lot-line city lot.
We replaced a corroded, non-impact 6-foot aluminum slider on a CBS ranch in the Sherwood Forest neighborhood with a PGT 5700 Series impact-rated slider carrying a Florida Product Approval and large-missile rating. The job required removing the original jalousie panels in the adjacent family room to satisfy the homeowner’s Citizens Insurance wind-mitigation inspection. We coordinated direct-to-site delivery from our West Palm Beach yard so the crew could stage on the driveway without blocking the narrow single-lane street. That’s the kind of detail that matters in Greenacres.

FAQs - Sliding Glass & Patio Doors in Greenacres
Because the frame, not just the glass, carries the impact rating. Original aluminum sliders from the 1970s through 1990s were never tested or approved for the wind pressures Greenacres faces. The inspector checks for a Florida Product Approval number on the frame and glass. No number, no credit, regardless of how solid the glass looks. Call (561) 660-9539 and we’ll tell you exactly what your inspector will look for.
No. Wind-mitigation inspectors will not grant partial credit for a single impact-rated opening if unrated jalousie windows remain on the same structure. Jalousie panels cannot be retrofitted to any recognized impact rating, so they get flagged as full replacements automatically. In Greenacres, this means a patio door replacement often becomes a whole-house conversion. We scope it honestly from the first visit and give you a written quote that accounts for every opening, not just the door.
Greenacres sits 12 to 15 miles inland from the Atlantic, which sounds protective, but the salt-laden humidity travels onshore daily. Aluminum frames corrode faster, weatherstripping degrades faster, and glazing seals fail sooner than they do in drier inland areas. A non-impact slider in Greenacres typically lasts 15 to 20 years before it needs major work. An impact-rated unit with a properly flashed threshold will outlast that, and it’ll qualify you for premium credits the old door never could.
Yes. We provide Florida Product Approval numbers, design pressure ratings, and installation details for every opening we touch. We know what Citizens Insurance and private-carrier inspectors in Palm Beach County require, and we make sure the paperwork is ready before they walk through your door. Free second opinions on written estimates are always available, and we’ll show you the documentation standard before you commit.
Most Greenacres homeowners see a noticeable drop in their cooling bill during the summer months, because the original single-pane sliders let heat pour into the living room all afternoon. A low-E insulated impact unit reflects solar heat and seals the opening properly, which typically cuts heat gain through that opening by roughly 40 to 50 percent. Exact savings depend on orientation, shading, and your HVAC system, but the combination of lower cooling costs and windstorm premium credits usually makes the upgrade pay for itself over time.
