Why Winslow Windows & Doors Is South Palm Beach’s Preferred Window Installation Company
Ed Winslow started this company in 2011, and his name still goes on every job we do. When a South Palm Beach condo board approves a window replacement project, they’re not buying a product off a shelf. They’re hiring someone who will show up inside their residents’ homes, work around retiree schedules, coordinate with property management, and stand behind the install for decades. That’s the job we do.
Our crews know the buildings along South Ocean Boulevard, the towers near Lantana Road, and the mid-rises clustered around the Intracoastal side. We’ve replaced windows in enough 1960s-1980s concrete-and-stucco structures to know what’s waiting behind the drywall before we open the first opening. Background-checked, uniformed technicians arrive on schedule, introduce themselves by name, and treat every unit as if Ed were standing in the hallway.
We’re an authorized installer for PGT, CGI, CWS, among others. That matters in South Palm Beach because these buildings need Miami-Dade NOA approved products with specific design pressures, and we pull from a brand lineup engineered for exactly this wind zone. We also publish our address and license number. No shell companies, no subcontractor roulette.
Our Window Installation Services in South Palm Beach
Single & Double Hung Windows
Most South Palm Beach condos still have their original single-pane aluminum sashes. Those frames pit and corrode from the double salt-air exposure, and eventually the sashes bind so badly they won’t open. We replace them with impact-rated single- and double-hung units that operate smoothly and meet the HVHZ large-missile requirement. PGT and CGI both offer NOA-approved hung windows in sizes that match the existing concrete openings, which keeps board approval moving.

Horizontal Roller Windows
Horizontal rollers are common in the bathrooms and kitchens of these older towers. Salt gets into the tracks, the rollers seize, and tenants start forcing them, which bends the frame. We install horizontal roller windows with stainless steel tracks and marine-grade hardware that holds up to Intracoastal air far longer than the original aluminum. The price difference over an inland-spec unit is modest. Replacing rusted tracks twice is not.

3-Panel Sliding (3-Lite Roller) Windows
These are the big ones. South Palm Beach condos love the wide ocean views, and our Sliding Glass & Patio Doors in South Palm Beach deliver them with 3-lite sliders. But a 3-panel slider in a 12th-floor unit off South Ocean Boulevard takes a beating from both the Atlantic fetch and the tidal air. We install 3-lite roller windows with laminated impact glass, reinforced interlocking rails, and rollers built for constant salt and sand exposure. Most of these jobs are part of building-wide phased replacements because the HOA wants uniform sightlines across every balcony.

Casement Windows
Casement windows seal tighter than any other operable style, and on a barrier island that matters. The crank mechanism pulls the sash hard against the weatherstripping, which keeps wind-driven rain from working through the perimeter seals during a summer squall. We install PGT and CGI casements in South Palm Beach high-rises regularly, using stainless hinges and multi-point locking hardware that won’t seize in the salt.

Common Window Installation Problems We See in South Palm Beach Homes
- Corroded aluminum frames from dual salt-air exposure. The Atlantic is on one side of this island and the Intracoastal on the other. Original aluminum frames oxidize from both directions, pitting the surface until the sash jams, the jamb cracks, or the perimeter seal lets moisture behind the stucco.
- Non-impact single-pane glass. These 1960s-1980s buildings predate Florida’s HVHZ large-missile requirement. A 2×4 at 34 mph goes straight through original single-pane glass, and board members know it after the first post-Surfside engineering review.
- Seized sliding door tracks and rollers. Salt and sand work into the bottom track of balcony sliders and the door won’t close, let alone hold pressure during an evacuation window. Milestone inspection reports routinely flag these as egress failures that must be corrected.
- Failed perimeter seals on aging window systems. The original caulk and glazing tape in these towers has dried, cracked, and pulled away. Water infiltrates around the frame and into the concrete, and the repair bill compounds every year it goes unaddressed.
Pricing for Window Installation in South Palm Beach, FL
A standard impact single-hung installed in South Palm Beach runs $900 to $1,800 per window. A 3-lite roller slider in a high-rise unit costs between $2,500 and $5,000, and a full one-bedroom unit replacement typically starts around $8,000. The two biggest price drivers here are the wind zone and the floor height, because both dictate the required design pressure and the glazing spec for Energy-Efficient Windows - South Palm Beach. Frame material matters too: marine-grade aluminum with a factory finish runs more than standard aluminum, but it’s the only frame we specify on this island. Every quote is a written, line-item price.

What Window Installation Costs in South Palm Beach
Impact windows in South Palm Beach generally land between $800 and $1,500 per window installed. Standard impact single-hungs run $900 to $1,800. Large or custom openings, which are common in the corner units and ocean-facing great rooms of these towers, go $2,500 to $5,000. Whole-home packages across a two-bedroom condo range $8,000 to $25,000 or more, depending on the number of openings and whether you’re replacing sliders alongside the windows. In South Palm Beach specifically, floor height pushes the engineering requirements and the labor costs up, because high-rise work moves slower and takes more staging. The free in-home measure and written quote is how you’ll know your exact number. Call (561) 468-6136 and we’ll set it up.

Florida Pays You Back
If you’re replacing windows in South Palm Beach, there are state and federal programs that put real money back. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and impact windows are a primary eligible item. Florida also exempts impact-resistant windows and doors from sales tax, which saves real money on a multi-opening project. On the federal side, the 25C energy credit covers 30% of product cost up to $600 per year on qualifying units. Many property insurers here apply a windstorm premium credit, averaging around 25% on the wind portion, after a wind mitigation inspection that runs $75 to $150. No one can promise what your carrier or the program administrators will approve, but we’ll help document the work properly so you can file with the right paperwork in hand.

FAQs - Window Installation in South Palm Beach
Because the Florida Building Code places South Palm Beach in the High-Velocity Hurricane Zone, and NOA is the product-level certification that proves a specific window meets the large-missile impact and pressure cycling requirements for this zone. Palm Beach County’s broader impact code says windows must be impact-rated, but NOA provides the engineering documentation per configuration and design pressure that condo boards, structural engineers, and Milestone inspectors need to sign off. Most boards won’t approve a product without a current NOA number that matches the opening’s required design pressures. Call (561) 468-6136 and we’ll pull the right documentation for your building before you go to the board.
Salt air attacks window frames and hardware from two directions in South Palm Beach, which roughly doubles the exposure of a single-coast town like Lake Worth. Aluminum frames pit and oxidize faster, stainless or galvanized hardware corrodes sooner, and sliding tracks collect salt and sand that seize rollers. Inland, the same window might last 20 years. On this barrier island, we specify marine-grade finishes and stainless hardware specifically for that dual-exposure reality. If your building is seeing corrosion at year eight, the fix is a materials upgrade, not another coat of paint. Call (561) 468-6136 for a walkthrough and a written assessment.
We recommend marine-grade aluminum with a factory-applied finish and stainless steel hardware for any South Palm Beach replacement. The original 1970s frames were standard aluminum, and the ocean and Intracoastal air destroyed them. PGT, CGI, and CWS all offer high-performance aluminum product lines with coastal finishes rated for this environment, and we provide South Palm Beach Therma Tru service as well. Vinyl is an option in some inland applications, but on this island we push aluminum for the structural strength and the longevity against the salt. Call (561) 468-6136 for a free opening-by-opening review.
Yes, impact windows in South Palm Beach are eligible for windstorm premium credits when a licensed inspector completes a wind mitigation report after installation. The report documents the opening protection and the product approval numbers, and you submit it to your insurer. For condo associations, the board usually files the building-wide documentation and distributes the credit information to unit owners. Expect the inspection to cost $75 to $150. We provide the NOA numbers and installation documentation your inspector needs. Call (561) 468-6136 to schedule the install and we’ll hand you the full paperwork packet for your carrier.
Casement windows seal tighter than hung or roller windows because the crank mechanism compresses the sash against the weatherstripping on all four sides, which keeps wind-driven rain out of high-rise openings during a squall. In a South Palm Beach condo, that tight seal means less water migration around the frame and fewer corrosion problems long-term. We install PGT and CGI casements for this application, configured with NOA-approved impact glass and stainless hardware. Call (561) 468-6136 and we’ll look at the openings in your unit.
The South Palm Beach Difference: Salt Decides the Spec
We recently replaced original single-pane aluminum windows in a 1970s-era high-rise south of Lantana Road. The sashes were so corroded from Intracoastal air that two jambs snapped during removal. The condo board had phased the project across all twelve floors to keep the aesthetics uniform and satisfy the post-Surfside Milestone inspection. We installed PGT impact-rated double-hung units with laminated glass interlayers and stainless steel hardware. That job is what Window Installation looks like on this island: not a weekend window swap, but a building-wide material correction driven by a specific failure mode.
South Palm Beach is not like Boynton Beach, a few miles inland. Here, the salt air comes from the Atlantic on one side and the Intracoastal on the other, and the original aluminum frames in these 1960s-1980s condominium towers take corrosion from both directions. That’s why the material spec on this page matters more than the schedule. Stainless fasteners instead of galvanized. Marine-grade aluminum instead of standard. Sealed perimeter joints instead of a bead of caulk. The cheap spec, the one that looks fine on an inland estimate, fails within a decade here and the building pays for it twice.
There’s a real price gap between a coastal-spec and an inland-spec window job in South Palm Beach. A standard aluminum frame with standard hardware might save 10 to 15 percent up front. But on a barrier island with dual salt-air exposure, that saving disappears into seized rollers, pitted frames, and perimeter leaks within a few hurricane seasons. We don’t give customers the inland spec here. We specify for the island. That’s the honest answer, and it’s what Ed would tell you face to face.
