Overview
Installation is the variable that decides whether your impact windows actually perform when you need them.
You can buy the best PGT or CGI unit on the market and still have it leak, whistle, or fail an inspection if it's set into a buck that wasn't shimmed flat, anchored to spec, or flashed in the correct sequence. The product's Miami-Dade NOA only protects you if the install follows the install instructions. That's where most South Florida jobs go wrong, and it's where ours don't.
Modern Window Solutions installs across two distinct project types: new construction (vertical builds, additions, full home rebuilds where the rough openings are framed for fin-frame units) and full-home replacements (existing homes where we're pulling old single-pane units out of a CBS block wall and dropping in a block-frame retrofit). The product is similar; the install detail is completely different. Quoting them the same way is a tell that a contractor doesn't really do both.
We're set up for both. Same in-house W-9 crew, same project manager, same permit clerk. You won't get handed off to a different installer once you sign.
Fin vs Block
Fin-frame for new construction. Block-frame for CBS retrofits.
Fin-frame (nail fin): the window has an integral perimeter flange that nails or screws into wood sheathing or a wood-buck rough opening. It's installed before stucco, tied into the weather-resistive barrier, and flashed as part of the wall assembly. It's the right detail for new builds, additions, and the rare South Florida home with wood-frame construction.
Block-frame (replacement frame): the window has a frame designed to set directly against the perimeter of an existing concrete-block opening, anchored with Tapcons through the jamb into the block. The old unit comes out, the buck and sill are inspected and rebuilt where rotted, the new unit is set in a bed of sealant, anchored to the engineer-stamped pattern, and perimeter-caulked inside and out. This is what 90% of our Broward and Miami-Dade homes need. CBS is the dominant construction type from the 1950s on.
Picking the wrong frame style on a retrofit is the #1 reason a permit fails. A fin-frame unit forced into a block opening means cutting and patching stucco around every window, a week of extra work, ugly seams, and a leak path waiting to open. We field-verify before we order.
On every replacement we also re-set the buck if it's failing, replace any rotted sub-sill, re-tie the structural opening per the NOA anchor pattern, and re-flash the head and sill. Stucco patches are sponge-finished to match texture, then color-matched to your existing wall. The goal: the inspector signs off, and your neighbor can't tell where the patch ends.
