CWS Window Replacement: The Fountainebleau Owner’s Guide

We replace CWS window components throughout Fountainebleau, with most residential jobs landing between $350 and $1,100 per window installed, depending on the part and glass package. We carry common CWS hardware on our trucks, and most replacements can be completed in one visit. If you’re reading this, you’ve probably noticed a window that won’t lock, a sash that drags, or glass that’s fogged between the panes and won’t clear.

Fountainebleau’s humidity and salt air accelerate wear on window hardware faster than most owners expect. Seals that handle dry climates for 20 years give out here in 10. Roller assemblies that glide smoothly in less punishing environments gum up with corrosion in five to seven. Ed Winslow has been replacing CWS components in this neighborhood long enough to know exactly what fails first, and what’s worth repairing versus replacing outright.

One thing to know: we’re an independent service provider, not affiliated with CWS. That works in your favor because we stock OEM and quality aftermarket parts that match CWS windows without the markup or delay of going through a manufacturer channel.

Which CWS Models This Applies To

CWS builds several window lines, and the part you need depends on which series you have. The most common models we see in Fountainebleau homes are the CWS Series 520 and 540 single-hung and horizontal rolling windows, along with the 7700 Series impact-rated linea and their casement and awning lines from the 5900 and 7000 families. Each series uses different roller diameters, keeper styles, and lock hardware, so matching the right part matters.

Here’s the compatibility gotcha we run into constantly: two visually identical CWS windows from different manufacturing years often use different balance shoe widths or roller stem lengths. A part that looks right out of the box won’t seat correctly by a matter of an eighth of an inch. Before ordering or pulling a part off the truck, we confirm the exact glass etching or serial label in the corner of the sash, or measure the component directly. That single step separates a window that opens like new from one that binds, rattles, or blows out the frame three months later.

On the OEM versus aftermarket decision: CWS OEM hardware is quality stuff, but supply chain interruptions have made some component lines hard to get quickly. We stock aftermarket equivalents from manufacturers with proven track records, and for most CWS rollers, balances, locks, and weatherstripping, the aftermarket option performs identically while cutting the wait. For impact-rated assemblies, we source only components rated to the same pressure standards the original window met. No downgrades, ever.

Signs Your CWS Window Replacement Is Failing

• Hard to open or close, especially on cooler mornings. The rollers or balance shoes have worn down or corroded. Fountainebleau humidity rusts the bearing in the roller, and once the ball bearings stop spinning, the sash stops gliding.
• The sash drops an inch when you unlock it. The spring balance or block-and-tackle system has given out. This is a counterweight failure, not just stiffness, and it gets worse fast as the remaining springs take the extra load.
• A draft around closed window frames. The weatherstripping has compressed or rotted. On west-facing windows in Fountainebleau, UV exposure hardens the pile and fin seal to the point where it cracks off in chunks.
• Condensation between the glass panes. The insulated glass unit seal has failed. In this climate, even a single failed seal lets salt-laden moisture inside the airspace, which is why you see that permanent haze that won’t wipe away.
• The lock won’t engage or the keeper slips. The cam lock or keeper has worn or the sash is misaligned. This is the one we tell people not to ignore because a window that won’t lock is also a window that won’t seal against wind-driven rain during hurricane season.

Replacement Cost & What’s Included

For CWS window parts in Fountainebleau, here’s what we typically see:

• Roller assemblies: $350-$550 per window installed, including removal of the sash, replacement of both rollers, track cleaning, and lubrication.
• Balances or spring systems: $380-$600 per window, depending on whether it’s a simple coil replacement or a full block-and-tackle swap.
• Lock and keeper sets: $250-$400 per window, including alignment so the lock actually engages.
• Weatherstripping and sealing: $250-$450 per window, using compression pile and fin seal matched to your CWS profile.
• Insulated glass unit replacement: $600-$1,100 per sash, depending on size and whether it’s standard or impact-rated glass.

Every quote is a line-item price: parts, labor, disposal of the old assembly, and cleanup are all spelled out before we start. We don’t do the lowball estimate with a surprise change order later. The work carries our Done Right Promise, which means if something we installed isn’t right, we make it right. That’s been our standard since 2011.

DIY or Call Us?

You can absolutely identify the problem from the signs above, take a photo of the window label or sash etching, and measure the rough opening or the part in question. Many Fountainebleau customers do exactly that before calling, and it makes the first conversation faster. The swapping itself, though, gets tricky fast. CWS impact windows are heavy. A full sash on the 7700 line can weigh 60 to 80 pounds depending on glass thickness, and taking one out without releasing the tension or supporting the frame correctly can damage the track, break the glass, or hurt you.

If you’re comfortable with basic tools and the part is a simple lock or weatherstrip, that’s doable. But for balances, rollers, and anything involving removing the sash, we’d rather you call us. We’re at (727) 620-6983, and a live person answers, not a voicemail tree. If we come out and find it’s a simpler fix than you expected, we’ll tell you that and charge accordingly.
