CWS Window Installation: The Fort Lauderdale Owner’s Guide

If you have a CWS window in Fort Lauderdale that needs professional installation, we handle it from first measurement to final caulk line, with most CWS window installations running between $850 and $2,400 per opening depending on size, series, and whether we’re doing a full-frame replacement or an insert. We’re an independent local installer that works on CWS products regularly, and in most cases we can get your window measured and scheduled within a few days, not weeks. The way most Fort Lauderdale homeowners find us is the same every time: a window that suddenly won’t close square, condensation between the panes that wasn’t there last hurricane season, or a frame that’s started weeping rust-colored streaks onto the stucco.

Which CWS Models This Applies To

CWS manufactures several distinct product lines, and the installation approach differs meaningfully between them. The most common CWS series we see in Fort Lauderdale homes are the CWS 600/800 series (aluminum single-hung and horizontal slider), the CWS 960/970 impact-rated casement and fixed windows, and the CWS acoustic-thermal series popular in condos near the Intracoastal and along Las Olas where both noise and wind-load requirements come into play. The quickest way to identify what you have: look at the aluminum frame’s interior corner or the spacer bar between the glass panes. CWS stamps a small etching with the manufacturing date and series code. It’s faint, but a phone flashlight at an angle usually picks it up. If the etching is gone, we measure the frame depth and glass thickness to narrow it down.

One CWS-specific compatibility gotcha: the 600 series uses a narrower frame profile than the 800 series, even though the glass packages look nearly identical from the outside. Grabbing an 800-series insert for a 600-series rough opening will leave you with a window that technically fits the hole but binds on the crank mechanism within six months. We’ve corrected that exact mistake for Fort Lauderdale homeowners more times than we’d like to count, usually on windows installed by a general contractor during a flipper renovation. When it comes to OEM versus aftermarket components like balances, weatherstripping, and glass packs, we stock CWS-spec components on our trucks for the 600, 800, and 960 series because those three cover maybe 80 percent of what’s in the ground across Broward County. For less common CWS series, we order directly through our CWS supply channel, and that typically adds three to five business days.

Signs Your CWS Window Installation Is Failing

• Visible daylight or drafts around the frame perimeter. This usually means the original installation shims have compressed or shifted, or the exterior sealant has dried and separated from the rough opening. In Fort Lauderdale’s humidity cycle, cheap latex caulk fails against aluminum frames inside of two years. We cut it out and re-seal with commercial-grade polyurethane.
• Condensation or fogging between the glass panes. The insulating glass unit’s seal has failed. CWS windows use a dual-seal spacer system, and when the outer seal degrades from salt air and UV, moisture gets in. The glass has to be replaced as a unit; you can’t dry it out and reseal it. In Fort Lauderdale, where we sit under relentless sun and marine air, a CWS 600-series glass pack typically lasts twelve to fifteen years before this happens.
• Sticky or binding operation on sliders and casements. CWS sashes ride on nylon rollers or hinge hardware that accumulates salt and sand grit in coastal neighborhoods like Harbor Beach and Rio Vista. Forcing a stuck window is how rollers snap and casement arms bend. Stiff operation is fixable; a snapped roller means full hardware replacement.
• Rust staining or bubbling paint at the frame’s bottom corners. This points to internal water retention, usually because the original installers never drilled proper weep-hole drainage or the weeps are painted over. CWS frames are designed to drain, but a bad installation defeats that, and South Florida downpours find it fast. The fix is installation-level correction, not a touch-up.
• Interior drywall cracks spreading from the window corners. This means structural movement, often tied to a window that was installed without proper header support or with undersized fasteners. Older Fort Lauderdale homes built before modern wind-load codes are especially prone. We don’t patch and paint over this one; we open up the corner, inspect the rough opening, and fix what’s actually moving.

Replacement Cost & What’s Included

For CWS window installation in Fort Lauderdale, here’s what you can expect on price:

• Insert installation (reusing existing frame): $400 to $700 per window
• Full-frame replacement (new CWS window, new frame, new flashing): $850 to $2,400 per window
• Glass pack replacement only (same frame, new sealed glass unit): $350 to $900 depending on size and impact rating
• Hardware replacement (rollers, balances, hinges, locks): $95 to $375 per window including parts and labor

Your numbers land somewhere in those bands based on window size, impact versus non-impact glass, whether the existing opening is square or needs reframing, and what we find once the old window comes out. Every quote you get from us is a written line-item price before work starts, and that price doesn’t move on you mid-job. Ed Winslow’s name is on the door, literally. That means it gets done right. We don’t do change orders. The workmanship carries our 36500-Day Done Right Promise: if it’s not done right, we come back and make it right. No expiration-dodging fine print, no prorated nonsense.

DIY or Call Us?

You can do a few things yourself before you call: clear the track, check if the weep holes are blocked with debris, note exactly where the draft or binding occurs, and take photos of the CWS etching so we can identify the series before we arrive. What you shouldn’t do is attempt a DIY removal of a failed CWS window, especially an impact unit. Impact windows are heavy, often 150 to 250 pounds per sash depending on size, and the tempered laminated glass can kick back dangerously if it binds during extraction. In Fort Lauderdale’s wind-borne debris zone, the installation also has to satisfy Miami-Dade County product approval standards, which means specific anchoring schedules and flashing methods that a weekend toolkit won’t cover. If you’re replacing glass, the sealed unit is under pressure; cracking the edge mid-install can send it shattering across a room. Let us put a second set of hands on it. We do free estimates for Fort Lauderdale homeowners, and there’s no trip charge inside our home county. Call (904) 913-5886 and a live person answers, any hour, any day.
