Fast, Reliable Window Installation Across West Palm Beach
Window installation in West Palm Beach rarely means a simple swap-out. Between the salt air off the Lake Worth Lagoon, the wind-load requirements for a barrier island city, and the Historic Preservation Board’s rules in neighborhoods like El Cid and Flamingo Park, the wrong window creates problems you’ll be fixing for a decade. A typical impact-rated window installed here runs $800 to $1,500 per opening, and most jobs take one to three days once your units arrive. Call Winslow Windows & Doors at (561) 660-9539 and Ed’s name is on every job we do.
We’ve been installing windows along Flagler Drive, in Grandview Heights, and across the older CBS ranch neighborhoods of West Palm Beach long enough to know that the right material spec matters more here than almost anywhere else in Palm Beach County. Salt-laden air corrodes inland-grade aluminum in five years. Standard ferrous anchors rust inside masonry walls and separate the jamb from the rough opening. That’s why our Window Installation team starts every West Palm Beach job by checking what the house is actually built from, not just what the opening measures.
Why Winslow Windows & Doors Is West Palm Beach’s Preferred Window Installation Company
We’re locally owned and owner-operated. Ed Winslow founded this company in 2011, and he still answers the phone. There’s no call center, no ticket number, and no “we’ll get back to you within two business days.” A live person picks up 24 hours a day, seven days a week, because Hurricane Season doesn’t respect office hours and neither do failed window seals.
Our West Palm Beach Door Installation customers know the drill. In the historic districts, permits stall when a contractor submits standard impact sliders that the HPB rejects on sight. In the condo buildings along the Intracoastal, boards want Florida Product Approval documentation before they sign off. We handle both. Every technician who arrives at your door is background-checked and in uniform, so you know exactly who’s walking up the driveway before they ring the bell.
We stock marine-grade hardware and stainless fasteners for West Palm Beach jobs because the default stuff rusts. We’re authorized installers for eight premium brands, including PGT, CGI, and Therma-Tru, and we carry parts for local repairs that most installers would have to order from a warehouse in Fort Myers. And we back all of it with the Done Right Promise: if it’s not done right, we make it right. A lasting standard of accountability.
Our Window Installation Services in West Palm Beach
Single & Double Hung Windows
Single and double hung windows are the workhorses of West Palm Beach’s post-WWII CBS ranch neighborhoods. These homes were built on concrete block, so the masonry anchoring of new impact frames is different from wood-frame work. We prep the rough opening properly, seal the perimeter, and install units that meet Florida Product Approval for the 140 mph design pressure in this wind zone. A typical impact single-hung runs $900 to $1,800 per window installed.

Horizontal Roller Windows
Horizontal roller windows are common in older West Palm Beach homes built before air conditioning was universal, when cross-ventilation mattered more than anything. Many of the originals are aluminum frames with pitted tracks and seized rollers from decades of salt air. We replace them with new impact-rated horizontal rollers using stainless hardware and marine-grade finishes. If you live within a mile of the Lake Worth Lagoon, this is the spec you need, not the inland version.

3-Panel Sliding (3-Lite Roller) Windows
West Palm Beach Sliding Glass & Patio Doors like three-panel sliders open up a room in ways a double hung never can, which is why you see them on so many homes facing the water. The catch: a standard impact-rated single-lite slider won’t fly in a historic district. In Flamingo Park or El Cid, the HPB mandates replicated muntin patterns before they’ll hear about a permit. We source simulated divided-light impact units that satisfy the historic requirement and the wind code at the same time.

Casement Windows
Casement windows seal tighter than any sliding or double hung design because the sash compresses against the frame when closed. That matters in West Palm Beach, where wind-driven rain pushes through loose weatherstripping and rots interior plaster. The original steel casements in 1920s and 1930s Mediterranean Revival homes are almost always corroded beyond repair at the weep system. We replace them with impact-rated casements that match the original profile, often in aluminum-clad wood to satisfy the HPB.

Trusted Brands We Service in West Palm Beach
We’re authorized installers for PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr Glass service in West Palm Beach, Therma-Tru. For West Palm Beach customers near the Intracoastal, we regularly specify CWS and ES Windows for their marine-grade hardware options. For historic district replacements, PGT’s aluminum-clad wood units with simulated divided lights are a frequent fit. Because we stock parts for these brands locally, warranty service and hardware replacements don’t mean shipping your sash back to a factory.
Common Window Installation Problems We See in West Palm Beach Homes
- Corroded original steel casements and jalousie frames. The weep system fails within a decade under ocean-salt air, and water leaks into plaster and rots the sill. By the time you see the rust, the frame is usually too far gone to save.
- Inland-grade aluminum frames pitting and seizing. Hinges and locks lock up within five years near the Intracoastal. Replacement is the only real fix, so we specify marine-grade finishes from day one.
- Ferrous sleeve anchors rusting inside masonry walls. CBS ranches from the 1950s and 1960s used anchors that corrode from residual moisture. The jamb separates, air leaks around the impact unit, and the window no longer seals properly.
- Historic district permit rejections. The HPB rejects standard impact sliders in Flamingo Park and El Cid even when fully code-compliant. You need simulated divided-light units and a Certificate of Appropriateness before a building permit is issued.
Pricing for Window Installation in West Palm Beach, FL
We quote fixed prices, and the number on your invoice matches the number on your estimate. No change orders, no “we found something once we opened the wall” games. For West Palm Beach, impact windows generally run $800 to $1,500 per window installed. Impact single-hungs run $900 to $1,800. Large or custom openings, including picture windows and 3-panel sliders, run $2,500 to $5,000. Whole-home packages start around $8,000 and can exceed $25,000 depending on the opening count and frame material.
What moves the price in West Palm Beach specifically: whether your home sits in a historic district and needs SDL impact units with HPB approval, whether you’re within a mile of the Lagoon and need marine-grade hardware, and whether your house is CBS block or wood frame. Frame material matters too: vinyl is the most affordable, aluminum-clad wood costs more but often matches older architecture better. Call (561) 660-9539 and we’ll schedule a free in-home measure and give you a written line-item quote.
What Window Installation Costs in West Palm Beach
Let’s get specific, because vague pricing is how people get burned. Impact windows in West Palm Beach generally run $800 to $1,500 per window installed. Impact single-hung windows run $900 to $1,800. Large or custom openings, like a picture window in a living room or a 3-panel slider facing the water, run $2,500 to $5,000. Whole-home impact packages start around $8,000 and can exceed $25,000 depending on the opening count, frame material, and whether the home sits in a historic district requiring SDL units.
The coastal-spec version of a job costs more than the inland-spec version, and that price gap is real. Marine-grade stainless hardware adds perhaps $40 to $80 per window. Aluminum-clad wood with simulated divided lights adds several hundred per opening over a standard vinyl impact unit. The cheap spec fails within a decade near the Lagoon. The coastal spec lasts. We’d rather quote you the right number now than come back in five years for a replacement you shouldn’t have needed. Free in-home measure, written quote, no obligation.
Florida Pays You Back
West Palm Beach homeowners can stack multiple incentives on an impact window project. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades. Florida exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit covers 30% of product cost, up to $600 per year, on qualifying Energy-Efficient Windows - West Palm Beach units. And after a wind-mitigation inspection, which runs about $75 to $150, many carriers give a windstorm-premium credit averaging around 25% on the windstorm portion of your policy.
We won’t guarantee what your insurance company will do, because carriers set their own numbers and programs change. But we’ll give you the documentation that makes those credits and grants possible. The permit, the Florida Product Approval numbers, the wind-mitigation inspection report. No guarantees, just paperwork done right the first time.
Historic Windows, Modern Codes: What West Palm Beach Requires
In West Palm Beach’s designated historic districts, Flamingo Park, El Cid, Old Northwood, and Grandview Heights, the Historic Preservation Board requires a Certificate of Appropriateness before any building permit is issued. And this is where a lot of contractors get it wrong: the HPB will reject a completely code-compliant, impact-rated single-lite slider if it does not replicate the original window’s muntin pattern. Every job in a designated historic district requires sourcing simulated divided-light impact units and submitting HPB paperwork before the city will even look at a permit application.
This dual compliance demand, Florida Building Code wind-load impact ratings plus historic replication of 1920s to 1940s Mediterranean Revival profiles, creates a specialty niche that standard swap-out installers simply don’t serve. That’s the exact work we do. We replaced a row of corroded steel casements on a 1938 Mediterranean Revival home in El Cid, where the HPB approved only an impact-rated simulated divided-light wood unit to match the original five-over-one muntin layout. We installed PGT aluminum-clad units with laminated glass interlayers and marine-grade stainless hardware. The low-E insulated glass cut the owner’s cooling load immediately, and the new sashes met Florida Product Approval for the 140 mph design pressure.
Salt air near West Palm Beach decides materials, not schedules. Which window frames corrode early, which hardware seizes, which anchors rust inside a masonry wall. We specify stainless and hot-dip hardware, marine-grade finishes, and sealed joints on every job within a mile of the Lake Worth Lagoon. The inland-spec version of the same window costs less up front and fails within five to ten years. The coastal spec costs more and lasts. We’ll show you both numbers and let you decide with your eyes open.
Impact Windows vs. Hurricane Shutters
You have two ways to protect West Palm Beach windows from a storm: impact glass or shutters. Shutters cost less up front, but they only work if someone is home to hang them, and they do nothing for energy efficiency, noise, or day-to-day security. Impact windows protect permanently. There’s no panel to haul out of the garage at 2 a.m., no accordion track to bind, no memory required. They also cut cooling costs, block UV, and reduce street noise. Most West Palm Beach homeowners who choose shutters end up installing impact windows anyway within a few years. We’d rather install them once.

FAQs - Window Installation in West Palm Beach
Yes, both. In Flamingo Park, El Cid, Old Northwood, and Grandview Heights, the HPB must issue a Certificate of Appropriateness before the city will process a building permit. The HPB reviews your window’s profile, muntin pattern, and materials against the original construction. Standard impact sliders get rejected even when code-compliant. Call (561) 660-9539 and we’ll handle the HPB paperwork as part of the job.
Florida Product Approval suffices. Palm Beach County falls within Florida’s Wind-Borne Debris Region with design wind speeds around 140 mph, but it is outside the Miami-Dade/Broward High-Velocity Hurricane Zone. That means your windows need valid Florida Product Approval NOAs matched to the design pressure for the specific opening. We pull the product approval documents for every unit we install, so your inspector and insurer both have what they need.
The salt-laden air off the Lagoon and the Atlantic deposits chloride on aluminum surfaces. Within a mile of the water, standard inland-grade aluminum pits, and the hinges and locks seize within about five years. Marine-grade finishes and stainless hardware prevent this. That’s why Window Installation in West Palm Beach near the water always gets the coastal spec, never the inland one.
On a 1950s CBS ranch with original jalousie or single-pane windows, impact windows with low-E insulated glass typically cut the cooling portion of the electric bill by 15 to 25 percent during the summer months. The concrete block mass holds the cool air better once the glazing stops the radiant heat gain. You’ll also lose the drafts. Exact savings depend on the home’s orientation and insulation, but the drop is real, and the federal 25C credit offsets part of the product cost.
Yes, in most cases. After a wind-mitigation inspection, many Florida carriers give a windstorm-premium credit averaging around 25 percent on the windstorm portion of the policy for homes with impact-rated openings on every window and door. The inspection runs about $75 to $150, and we’ll provide the product approval documentation your inspector needs. Carriers set the final numbers, so we won’t promise a specific discount, but the credit is common among West Palm Beach homeowners with full impact protection.
