CWS Window Replacement: The Little Gables Owner’s Guide

If you’ve got a CWS window that’s fogged, cracked, or not closing right, we stock and install CWS-compatible replacement units for Little Gables homes most weeks for between $850 and $1,900 per window, installed. The glass is usually ready within three to five business days once we measure, and we handle the whole job from pulling the old frame to the final caulk line. Most Little Gables owners don’t call us until the window has already become a problem they’re living with daily: a bedroom that won’t cool properly in August, a lock that needs a shoulder shove, or condensation between the panes that won’t clear.

Which CWS Models This Applies To

CWS makes several distinct window lines, and the replacement glass or sash depends heavily on which one you have. The two we encounter most in Little Gables are the CWS Series 1900 and 2900 single-hung sliders, along with their casement and picture-window variants. The Series 1900 uses a thinner 1-inch insulated glass unit, while the 2900 steps up to a 1-1/8-inch unit with heavier extruded frames; the two are not interchangeable.

Find the sticker. CWS stamps a small white or silver label on the head jamb or top edge of the operable sash, usually carrying the series number, the glass make-up, and the date. If the sticker’s gone or faded, we can pull the glass unit itself, measure its exact thickness with a digital gauge, and match the spacer and low-E spec from there. One critical gotcha: some CWS frames shipped into South Florida in the late 2000s used a proprietary glazing bead that standard replacement glass won’t seat into without the correct CWS bead profile. We keep the right bead stock on the truck for that era, which most general handymen won’t.

For OEM versus aftermarket: CWS original glass is solid and we can source it through authorized distribution, but for many Little Gables homes the smarter buy is an aftermarket insulated unit with the same thickness, spacer, and low-E rating, often at 20 to 30 percent less. The frame is CWS; the glass is glass, provided the spec matches. We’ll tell you which route makes sense for your specific window before you spend a dollar.

Signs Your CWS Window Replacement Is Failing

• Fog or condensation between the panes: The seal around the insulated glass unit has failed. South Florida humidity seeps in, condensates, and leaves a mineral haze that cannot be cleaned off from either side. The fix is a new glass unit, not a cleaning.
• Water staining or soft drywall under the window: The frame’s weep holes are clogged or the exterior seal let go. In Little Gables we get torrential summer storms, and a CWS window that’s not draining will put water into the wall, not just the sill.
• Sash that’s hard to lift or won’t stay up: The balance system inside the jamb is worn out. On CWS single-hungs this is a replaceable cartridge; on older units it’s a coiled spring balance that has lost tension over a decade of use.
• Draft around the frame on windy days: The weatherstripping or the compression seal is flattened. You’ll feel it most on east-facing windows during afternoon sea breezes. The window isn’t sealing against Florida’s constant air movement.
• Lock that won’t engage or a sash that drifts slightly out of plane: The frame may have settled with the house, or the keeper and latch are worn. Little Gables has its share of older masonry homes; slight frame shifts over 20 years are common, and CWS frames respond well to re-shimming.

Replacement Cost & What’s Included

In Little Gables, a full CWS replacement window install typically lands between $850 and $1,900 per window, depending on glass type, series, and whether we’re replacing the glass only or the complete sash and frame. Here’s the honest breakdown:

• Insulated glass unit only: $210 to $460 for the unit itself, plus $95 to $180 labor per window.
• Full sash replacement: $380 to $780 for the CWS-compatible sash, plus $160 to $260 labor.
• Complete frame-and-all replacement: $850 to $1,900 installed, including the tear-out, new CWS or CWS-compatible window, insulating foam, interior trim repair, and exterior caulk and seal.
• Low-E and impact-rated glass: adds $120 to $400 per unit over standard glass, depending on size and whether you’re matching existing impact protection.

Every quote is line-itemed before we start: you’ll see the part cost, the labor, and any disposal fees separately, not buried in a lump sum. The Done Right Promise covers our installation work on every one of these projects. If the window isn’t right, Ed Winslow makes it right. That’s the whole deal. Seniors and veterans get 10 percent off the total, and any repair over $200 gets $40 off.

DIY or Call Us?

There’s a real difference between a window you can adjust and a window replacement you should not attempt. You can absolutely clean the tracks, clear the weep holes with a bent paperclip, and spray a dry lubricant on a stiff latch. Those are maintenance tasks, and they’re worth doing twice a year in Little Gables with the salt air and pollen we get.

But pulling a CWS sash or handling a 40-pound insulated glass unit is where good intentions turn into broken frames and cracked glass. The glazing beads snap when pried wrong, the corner keys crack, and without the right CWS bead profile the new glass won’t seat in those older frames. We’ve fixed dozens of DIY attempts that cost more than the original job would have.

If window replacement is a maybe, call (727) 291-4678 and we’ll talk through what you’re seeing. A good phone conversation costs you nothing, and often we can tell you if a simple adjustment solves it before we ever schedule a visit.
