Choose replacement windows unless you’re tearing a wall open or building from the studs. Here’s the honest way to tell.

New construction windows come with a nailing fin that mounts to the framing before siding or stucco goes on. Replacement windows slide into an existing opening and fasten to the surrounding frame. For almost every Greenacres homeowner with a standing house, replacement windows are the right call. New construction windows make sense only when the exterior is already stripped or the opening is being resized. Call us at (754) 339-0784 if you want a straight answer about which one fits your situation.

Why this question matters more in Greenacres than most places

Greenacres sits in Palm Beach County’s wind-borne debris region, which means any window we set here must carry Florida Product Approval ratings for design wind speeds typically 140 mph or faster. That’s a different requirement than the HVHZ certification Miami-Dade and Broward demand, and homeowners who shop windows online without knowing this can end up with product that won’t pass a Greenacres inspection.

Most of the homes we walk through in Greenacres are concrete block construction from the 1960s through the early 1990s. A substantial number still have their original aluminum-frame jalousie or single-pane windows, which predate Florida’s post-Hurricane Andrew code overhaul entirely. Those windows were never going to hold up to the kind of wind we get here, roughly ten to twelve miles inland with full hurricane exposure. Florida insurers have been declining renewals on homes with jalousie windows at rates that keep climbing. That’s why impact-rated full replacements are the dominant job type in this city, driven by insurance necessity as much as storm safety.

The local climate also works against any window that isn’t built for it. Year-round humidity, extreme UV intensity, and near-daily summer thunderstorms accelerate vinyl frame warping, seal failure, and aluminum oxidation. Dale Kessler, our owner, grew up off Jog Road in Greenacres and spent enough humid summers here to know exactly why the right window seal is not optional. He trained in glazing and building construction at Palm Beach State College, where the instructors still talked about reading a rough opening before you touched a tape measure. That training is why we measure every opening twice before ordering anything.

What actually separates new construction from replacement windows

Here’s the distinction in plain terms:

• New construction windows have a fin around the perimeter that nails directly to the framing. The window is installed before siding, stucco, or brick goes on. These are the right product when a wall is open or a house is going up. Using them on an existing home means cutting back exterior finish to reach the framing, which turns a window change into a construction project.
• Replacement windows are built to fit inside the existing opening. They’re installed into the pocket left by the old window, flash-sealed, and anchored to the surrounding frame. We can do this without disturbing the stucco or drywall on most Greenacres block homes, and a full-opening impact replacement can be completed in a single visit.

The product itself is often the same glass package, same frame material, same impact rating. What changes is how it mounts to the house and what gets disturbed in the process. For a Greenacres homeowner living in a CBS home with stucco exterior and working windows, a replacement unit is almost always the practical choice.

When new construction windows earn their keep

There are times when a new construction window is the only honest recommendation. If a contractor is already removing stucco or siding for another reason, adding fins costs nothing extra and gives the most complete weather seal possible. If the rough opening is being enlarged or moved during a renovation, the framing is exposed anyway, so new construction windows make sense. If the existing frame has rotted, twisted, or been installed out of square by a previous contractor, we’ll recommend restructuring the opening and using a finned unit so the window is actually right in the opening, not just shimmed into something that was never plumb.

Dale’s founding rule applies here: “If it is not right in the opening, it will not be right in ten years.” We’ve seen enough Greenacres homes where a previous installer forced a replacement window into an opening that was out of square by half an inch. The homeowner spends the next decade fighting a window that binds in July and leaks during the afternoon thunderstorms. A finned install would have fixed the opening properly from the start.

For Greenacres homes, the real decision is usually impact replacement

Most of the calls we take in Greenacres aren’t really about new construction versus replacement. They’re about getting rid of jalousie or single-pane aluminum windows before the insurance renewal comes. The city’s older neighborhoods still have a notable concentration of louvered glass windows, which offer zero hurricane protection and minimal energy efficiency by any measure. Those jalousie-to-impact conversions are a near-constant job type here, and they barely exist in the newer master-planned subdivisions of adjacent Wellington to the west.

When we convert a jalousie opening to a modern impact-rated replacement window, we’re working in what’s usually a concrete block opening. The existing frame mostly sits flush with the interior wall, and there’s rarely a cavity deep enough for traditional mounting methods. We use Florida Product Approved impact units, frequently from manufacturers like CGI, ES Windows, or ECO Window Systems, and set them to handle the wind loads Palm Beach County requires.

The comparative costs: what a homeowner should expect

Here’s a practical price picture for Greenacres, based on what we see across a typical year of quotes and completed jobs. These are replacement window ranges for a single opening. New construction windows run slightly higher on the install side because the exterior finish has to be restored.

These numbers are honest ranges, but every opening is different. We quote manufacturer lines side by side on paper so a homeowner sees exactly what they’re buying, and we register both warranty layers in writing before the truck leaves the driveway. That’s The Keystone Standard, and it’s the baseline for every job we do.

Why we lean toward full-opening replacement in Greenacres

When you’re replacing a window in an older Greenacres block home, there’s a strong argument for taking out the entire old frame rather than setting a pocket insert into the existing opening. The original frame on a 1972 home was never designed for the wind loads we now require. It was designed to hold a single pane of glass and a screen. By removing it, we can flash the opening properly, add sealant at the right points, and set a window that carries its own strength through the masonry. It’s more work up front, but it leaves you with something that stands up to what the afternoons here actually throw at it.

That’s why a typical full-opening impact replacement in Greenacres is the dominant job type. It solves the insurance letter sitting on the kitchen counter, it removes the louvered glass that was never insulation in the first place, and it gives you a window that someone will still be using thirty years from now. We’re happy to walk through that logic on the phone or in your living room, no pressure.
