Fast, Reliable Window Installation Across South Palm Beach
Window installation in South Palm Beach is a different animal than anywhere else in Palm Beach County. This barrier island strip, barely a quarter-mile wide between the Atlantic and the Intracoastal, is almost entirely condominium towers from the 1960s through early 1980s. Every job we do here has to clear two separate approval gates: Palm Beach County’s HVHZ impact glazing code, and whichever condo association’s architectural review board governs the building. We know both processes cold, and we schedule around them so your project doesn’t stall halfway through. Call (561) 928-0302 for a free in-home measure and written quote.
Why Winslow Windows & Doors Is South Palm Beach’s Preferred Window Installation Company
Ed Winslow founded this company in 2011 with a simple idea: put his name on the door and stand behind every job. Since then, our Window Installation team has worked up and down the South Palm Beach oceanfront, from the older towers near Lantana Road to the condominium clusters around Palm Beach Shores. We’ve replaced original jalousie windows on the 9th floor of beachfront buildings. We’ve coordinated with architectural review boards that meet once a month. We know which buildings require specific frame colors and which ones will accept Miami-Dade NOA product approvals without a fight.
Every technician who walks into your South Palm Beach unit is background-checked, uniformed, and trained on high-rise installation protocols. When you call, a live person answers. Not a call center, not a voicemail loop. Ed’s name is on the door, and on every job we do. Our Done Right Promise means something concrete: if it’s not done right, we make it right. Period.
Our Window Installation Services in South Palm Beach
Here’s what we install most often in South Palm Beach condominium towers, and what matters for each type in this specific environment.
Single & Double Hung Windows
Single and double hung windows are common in South Palm Beach bedrooms and bathrooms that face the Intracoastal side. In a high-rise setting, we specify HVHZ-rated sashes with reinforced meeting rails, because wind pressures on the 10th floor are dramatically higher than at ground level. Aluminum frames with marine-grade coatings hold up far better here than vinyl, which can warp under relentless salt-and-sun exposure.

Horizontal Roller Windows
Horizontal roller windows are everywhere in older South Palm Beach towers, and most originals are single-pane aluminum that leaks air and lets salt spray work into the track. We replace them with impact-rated, Low-E insulated rollers that glide smoothly even after years of coastal exposure. Stainless steel roller assemblies make a real difference on units within a block of the ocean.

3-Panel Sliding (3-Lite Roller) Windows
Three-panel sliders dominate the oceanfront balconies and great rooms in South Palm Beach. These are the windows that fail most aggressively here, because salt-laden moisture pools in the bottom track and eats the original aluminum from underneath. Our installs spec marine-grade hardware, weep-hole covers, and reinforced sills that direct water out instead of holding it. We also pre-build the condo board submittal package, with elevation drawings and Florida Product Approval numbers, so the architectural review doesn’t stall your timeline.

Casement Windows
Impact-rated casement windows are a strong choice for South Palm Beach corners and openings where you want maximum glass area and a tight seal against wind-driven rain. The crank mechanism creates compression against the frame that outperforms sliders in high-wind conditions. We install them with multi-point locking systems and heavy-duty stainless hardware that resists the corrosive salt air from both the ocean and the Intracoastal.

Trusted Brands We Service in South Palm Beach
We install and service products from authorized partner brands including PGT, CGI, ES Windows, and Therma-Tru. Each brand offers configurations with Miami-Dade NOA and Florida Product Approval numbers, which is the first thing your condo association’s review board will ask for. We keep current on every product line we install, and we know which glass packages clear Palm Beach County’s HVHZ inspection on the first pass. No mainland stock, no substitution games.
Common Window Installation Problems We See in South Palm Beach Homes
After hundreds of jobs along this stretch of shoreline, here are the failure patterns we see most often, and what we do differently.
- Condo board rejection due to incomplete submittal packets. Missing elevation drawings or outdated Miami-Dade NOA numbers stall projects for 4-6 weeks. We build the packet first and submit it before any permit is pulled, so your board reviews a complete file the first time.
- Water intrusion from omitted weep-hole covers. Without weep-hole covers, salt-laden moisture pools in the track and rots the new sash within a few seasons. We spec weep-hole covers as standard on every coastal install, not as an add-on.
- Use of non-HVHZ rated glass from a mainland supplier. A cheap mainland pane will fail Palm Beach County inspection and force a full re-order and re-install at high-rise labor rates. We only install glass rated for this exact wind zone.
- Corroded bottom tracks on original 6-foot sliders. The original 1970s aluminum sliders on oceanfront balconies corrode into lace within a decade. Our replacement spec uses marine-grade rollers and reinforced tracks that handle bidirectional salt spray from ocean and Intracoastal.
Pricing for Window Installation in South Palm Beach, FL
For a typical impact-rated single or double hung window in South Palm Beach, expect to pay between $900 and $1,800 installed, depending on opening size and floor height. Impact casement windows typically run $800 to $1,500 per window. A 3-panel sliding door or large custom opening can run $2,500 to $5,000. Whole-home packages across multiple openings frequently land between $8,000 and $25,000, with larger oceanfront units running higher. Pricing in South Palm Beach runs slightly above mainland Palm Beach County because of the high-rise labor rates, elevated wind-zone requirements, and the architectural review coordination we handle for you at no extra charge.

FAQs - Window Installation in South Palm Beach
Yes, most do. In addition to Palm Beach County’s HVHZ impact glazing code, nearly every South Palm Beach condominium tower has an architectural review board that dictates frame color, glass tint, mullion profile, and sometimes even the specific brand line allowed. Some buildings permit only aluminum frames in a specific anodized finish, while others accept painted finishes that match the original 1970s look. The board’s authority is separate from the county permit, and failing either one stops the project cold. We compile and submit the board package as standard practice. Call (561) 928-0302 and we’ll walk you through what your building requires before you spend a dollar.
Plan for 6 to 10 weeks of committee review before any permit gets pulled. Some South Palm Beach boards meet monthly, and if your submittal arrives the day after a meeting, the calendar just doesn’t move. Missing elevation drawings or Florida Product Approval numbers resets that clock and adds another 4 to 6 weeks. We schedule around this reality from day one, so the labor crew doesn’t arrive until approvals are in hand. The work itself is fast: once your units arrive, installation happens in as fast as a single day. The wait is in the paperwork, not the install. Call (561) 928-0302 for a free consultation and we’ll map the timeline for your building.
You need HVHZ-rated products with Miami-Dade NOA or Florida Product Approval numbers. A standard mainland window with non-impact glass will fail Palm Beach County inspection, and you’ll be paying to re-order and re-install at high-rise labor rates. The HVHZ rating is not a marketing term, it’s a structural requirement tied to the wind-speed corridor South Palm Beach sits in. We only install windows rated for this exact zone. Call (561) 928-0302 to confirm what your building and the county both require.
Bidirectional salt spray. The Atlantic on one side and the Intracoastal on the other means salt-laden air attacks the aluminum track from above while saltwater pools below. The original 1970s sliders had no weep-hole covers, so moisture sat in the track and corroded it into lace within a decade. We spec marine-grade hardware and weep-hole covers as standard, and we use track profiles designed to shed water instead of holding it. Call (561) 928-0302 for an exact replacement quote, and ask about our permanent 10% discount for seniors and veterans.
Yes, typically by a noticeable margin. Original jalousie windows leak conditioned air constantly, and single-pane glass transfers heat directly. Impact-rated Low-E insulated glass keeps the sun’s heat out while holding the cool air in, which matters in a South Palm Beach tower where the AC runs most of the year. Most owners also see windstorm-premium credits after a wind-mitigation inspection. Call (561) 928-0302 for a free estimate and we’ll show you the numbers for your unit.
What Window Installation Costs in South Palm Beach
For a typical impact-rated single or double hung window in South Palm Beach, expect between $900 and $1,800 installed. Impact casement windows run $800 to $1,500 per window. Large or custom openings, including the 6-foot oceanfront sliders common in South Palm Beach towers, run $2,500 to $5,000. Whole-home packages across multiple openings start around $8,000 and can reach $25,000 or more depending on opening count, floor height, and glass package selected. What moves the price here: the elevated wind zone requires heavier glass and stronger frames; high-rise work carries different labor and safety requirements than ground-level installs; and the condo board review coordination adds administrative time we absorb into the quote, not a surprise line item later. Our quotes are written, line-item, and fixed. No change orders after approval. Call (561) 928-0302 for a free in-home measure and exact pricing for your specific openings.
Florida Pays You Back
The incentives available to South Palm Beach owners can make impact windows substantially more affordable. 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 replacement. Florida also exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit applies at 30% of product cost, up to $600 per year on qualifying units. After a wind-mitigation inspection (typically $75 to $150), many South Palm Beach owners also see windstorm-premium credits averaging around 25% on the windstorm portion of their insurance premium. Final amounts depend on your insurance carrier and the specific program terms, but the stack is real. Call (561) 928-0302 for guidance on how these programs apply to your specific building and unit.
South Palm Beach’s Dual Approval Gauntlet - And How We Handle It
Here’s what makes window installation in South Palm Beach fundamentally different from anywhere else on the mainland. Your replacement window has to satisfy two masters: Palm Beach County’s HVHZ impact glazing code, which dictates the glass package, design pressure ratings, and frame anchoring, and your condo tower’s architectural review board, which dictates frame color, mullion profile, finish, and sometimes the exact brand line. This is not a suggestion. Miss either one, and the project stops dead.
The architectural review alone adds 6 to 10 weeks to the calendar in most South Palm Beach buildings. Boards meet once a month. If your submittal packet arrives the day after a meeting, you wait another month. If the packet is missing elevation drawings or Miami-Dade NOA product approval numbers, the board tables it, and you add another 4 to 6 weeks. That’s the hidden timeline mainland homeowners never face.
We build the submittal packet as part of every quote, before any permit is pulled. Elevation drawings, product approvals, frame finish samples, anchoring details, design pressure calculations matched to the specific opening. We file it with the board, track it through review, and schedule installation only after the committee signs off. Your project doesn’t sit half-finished waiting on a committee that meets once a month, because we don’t start demo until the paperwork is done.
One note on the brands we install here: PGT and CGI both publish Miami-Dade NOA numbers for their impact lines, and ES Windows manufactures high-end aluminum frames specifically engineered for corrosive coastal environments. We submit whichever configuration your board will approve, and we don’t guess. We know the reviewers at many of the major South Palm Beach towers, and we know which frame colors they’ve accepted, which mullion profiles match the original look, and which submittal formats get rubber-stamped the same month.
Our crew recently replaced a set of original 1970s 6-foot aluminum sliders on an oceanfront unit at the Palm Beach House condominium. The bottom tracks had corroded into lace from bidirectional salt spray, and the rollers had seized. We spec’d marine-grade hardware with weep-hole covers, submitted the elevation drawings and Miami-Dade NOA product approvals to the association’s architectural review board, and installed impact-rated PGT sliders after condo approval. The unit was secure through the next storm season, and the board got exactly what it asked for.
The Condo Reality in South Palm Beach
South Palm Beach is a razor-thin barrier island made up almost entirely of mid-rise and high-rise condominium towers from the 1960s through early 1980s. There are virtually no detached single-family homes here. Nearly every unit faces either the open Atlantic or the Intracoastal Waterway, which means the salt-air corrosion on original aluminum frames is constant, universal, and bidirectional. No side of a building escapes it.
Most of these towers still have original jalousie windows in the bedrooms and bathrooms, single-pane aluminum sliders in the living areas, and hollow-core entry doors that do nothing against wind-borne debris. The Florida Building Code has moved far beyond what these buildings were built to, and that gap is why we do so much work along this strip.
When we meet a South Palm Beach owner for the first time, we usually find three things: original jalousie windows leaking conditioned air, aluminum sliders with corroded tracks that don’t close tight, and a condo board that’s been promising a window program for years. We handle all three. The windows, the doors, and the board packet.
Impact Windows vs. Hurricane Shutters
A common question from South Palm Beach owners: should I install impact windows or keep my hurricane shutters? The practical answer is that impact windows give you permanent, always-on protection without panels to haul out and hang before every storm. In a high-rise, that matters. You can’t easily hang shutters on a 12th-floor balcony in high wind, and many boards restrict exterior shutter hardware anyway. Impact-rated windows also reduce outside noise, which owners near A1A appreciate, and they earn windstorm-premium credits that shutters alone may not. Call (561) 928-0302 and we’ll walk through the cost difference for your specific openings.
