How custom windows are made in Greenacres, FL: from rough opening to finished sash

Custom windows are built to the exact measurements of your rough opening, then assembled with frame material, glass package, and hardware you select before the first cut is made. In Greenacres, the process almost always includes Florida Product Approval ratings for Palm Beach County wind speeds, because most of the homes we measure were built with concrete block openings that have shifted over fifty years of humidity and afternoon thunderstorms. If you’re replacing original jalousie or single-pane aluminum in a 1960s CBS home, the measurements rarely match what the builder intended in 1972. Call (754) 339-0784 and we’ll measure every opening twice before we order anything.

What actually happens between the order and the install

Dale Kessler, Owner at TruePane Windows & Doors, grew up off Jog Road in Greenacres and has been setting frames in Palm Beach County for going on two decades. He’ll tell you the same thing his instructors at Palm Beach State College drilled into him: read the rough opening before you touch a tape measure. That’s where a custom window starts. Not in a catalog, not in a showroom display, but at the wall itself.

Here’s the sequence, the way we run it on every job in Greenacres:

• Measure, then measure again. We check the rough opening at three points vertically and three horizontally, because CBS walls settle and shift. An opening that’s square at the sill can be off by three-eighths of an inch at the header. Custom means the window is built for the wall you have, not the wall the builder drew.
• Select the frame and glass package. In Palm Beach County, that decision usually starts with impact rating. We quote manufacturer lines side by side on paper so you see exactly what you’re buying. For Greenacres homes that means options from CGI, CWS, and ES Windows more often than not, because those lines carry Florida Product Approvals matched to our design wind speeds, which typically run 140 mph or higher in this region.
• Factory fabrication. The window is cut, welded or mechanically joined, glazed, and sealed to your exact dimensions. For vinyl, that means fusion-welded corners. For aluminum, mechanically fastened with thermal breaks where specified. The insulating glass unit is built to your glass package: laminated impact glass, low-E coatings, argon fill, whatever the opening calls for.
• Delivery and dry-fit. Before we set anything, we dry-fit the window in the opening. This is the step that separates a custom job from a stock replacement. If the pane is not true, the job is not done. That’s the rule that names the company, and it applies here before a single screw goes in.
• Set, shim, and seal. The window is shimmed square and level, anchored to the CBS structure, then sealed against water intrusion with the flashing and sealant system specified for block construction. South Florida humidity doesn’t forgive a skipped step here.

Why Greenacres homes make custom windows the rule, not the exception

Most of Greenacres was built between the 1960s and early 1990s, and a substantial portion of those homes still carry original aluminum-frame jalousie or single-pane windows that predate Hurricane Andrew’s code overhaul entirely. Those openings were never standardized. They were framed to fit the jalousie units of the day, which means a stock window from a big-box aisle won’t drop in without carpentry compromise. Custom fabrication means the window matches the opening, not the other way around.

There’s a second reason custom is the norm here: insurance. Greenacres sits in Palm Beach County’s wind-borne debris region, outside Miami-Dade and Broward’s High Velocity Hurricane Zone. That means our windows and doors must carry Florida Product Approval for PBC design wind speeds, typically 140 mph or higher, rather than HVHZ certification. Florida insurers have been declining renewals on homes with original jalousie windows at increasing rates. When a homeowner in the older neighborhoods near Lake Worth Road calls us, the conversation usually starts with an insurance letter on the kitchen counter. Custom impact-rated replacements, documented with both warranty layers registered in writing, are often the only way to keep the policy.

The climate does the rest of the persuading. We get full hurricane wind exposure here, with less salt spray than the beachfront but the same brutal UV, year-round humidity, and daily summer thunderstorms. That combination accelerates vinyl frame warping, seal failure, and aluminum oxidation on anything that isn’t impact-rated. A jalousie window that’s been baking since 1975 isn’t just drafty. It’s structurally done.

What custom windows cost in Greenacres, in real numbers

Custom window pricing depends on the frame material, the glass package, and the opening itself, but here’s what we see on the ground in Greenacres:

These ranges reflect the specific approval environment in Palm Beach County. Impact-rated glass packages add cost, but they’re also what makes the home insurable here. We quote each manufacturer line side by side on paper before you commit to anything, and the price you get is the price on the bill. No surprise line items. No second appointment left hanging. Our custom windows and doors page in Greenacres walks through the process in more detail if you want to see what a full replacement typically involves.

The difference between a quote and a commitment

We register both manufacturer warranty layers in writing before the truck leaves the driveway, with durations stated on the paperwork. That’s the Keystone Standard, and it’s the reason a homeowner who’s been burned once doesn’t have to guess what they’re covered by. We also back every job with a Done Right Promise. If something isn’t right, we make it right. No arguing, no fine print that covers neither.

Dale’s father was a carpenter, which is how Dale ended up holding shims at age twelve. That early start is probably why he’s still more comfortable on a job site than anywhere else. The work he’s best known for is impact-rated installations that pass inspection the first time, not after a callback. If it is not right in the opening, it will not be right in ten years. That’s not a slogan. It’s the reason we measure every opening twice, dry-fit before we set, and register warranty layers before we leave.

Custom windows aren’t a product you order. They’re a result you engineer for a specific wall, in a specific climate, under a specific code. Greenacres has all three in abundance. If you’re still living with jalousie windows and an insurance renewal letter that’s making you nervous, it’s time to talk to a local contractor who’s been doing this in Palm Beach County for two decades.
