CWS Window Replacement: The Fort Myers Owner’s Guide

If you have a CWS window that won’t seal, won’t lock, or has a fogged or cracked pane, we stock CWS-compatible replacement parts and install them across Fort Myers. A full CWS window replacement in Fort Myers typically runs $700-$1,400 per window installed, depending on size, glass package, and whether it’s an impact-rated unit. Most single-window swaps are completed in one visit, and if we’re replacing a failed part rather than the whole sash, the price drops considerably.

Here’s how owners usually find us. The window still looks fine from across the room, but it’s gotten harder to open over the past few months. Or the latch doesn’t catch anymore. Or there’s moisture trapped between the panes that won’t wipe away. By the time a CWS window reaches that point in this climate, the part has usually been fighting salt air, humidity, and sun for years, and it’s done.

We’re an independent Fort Myers window and door company, not affiliated with CWS. That matters because it means we give you straight answers about whether an OEM CWS part or a quality aftermarket equivalent is the smarter spend for your situation, not the answer a manufacturer’s warranty department wants you to hear.

Which CWS Models This Applies To

Over the years, CWS has put out several window lines in Southwest Florida, and parts are not interchangeable between all of them. The three we see most often in Fort Myers are the CWS 880 Series single-hung, the CWS Estate Series casement, and the CWS Architectural Series, which shows up on many mid-2000s builds east of I-75. Each series uses different balance systems, different locking hardware, and different sash dimensions, so matching a replacement part starts with identifying the series, not just measuring the glass.

How to identify what you have: look for the CWS etched logo in the corner of the glass, which includes the manufacturing date code, or check the metal spacer between the panes. If neither is readable, measure the visible glass width and height to the nearest 1/8 inch, and take a close-up photo of the lock and the side of the sash where it meets the frame. We can usually identify the series from that photo alone.

On the OEM versus aftermarket question: CWS OEM parts are available for most series, and for the 880 Series we generally recommend them because the balance system tolerances are tight and aftermarket versions tend to sag within a year or two. For weatherstripping, corner gaskets, and most lock sets, quality aftermarket parts perform just as well and cost 30-50% less. We’ll show you both options with real numbers and let you decide.

Signs Your CWS Window Replacement Is Failing

• The sash drops when you raise it. The block-and-tackle balances inside the frame have lost tension or the cord has snapped. In Fort Myers humidity, the cords inside these balances break down faster than in drier climates, and the failure is often sudden, not gradual.
• Condensation appears between the panes. The insulated glass seal has failed. Once the desiccant inside the spacer strip is saturated, which takes about four to seven years in Southwest Florida’s humidity, the fog is permanent and the only fix is new glass or a new sash.
• The lock won’t engage or feels loose. CWS locking hardware from the 2000s was often aluminum, and salt air eats anodized aluminum. The keeper on the frame can wear to the point where the latch passes right over it. This is a part-only fix if caught early.
• You can feel air moving around the window on a windy day. The weatherstripping has compressed or rotted, and the sash no longer seats. In Fort Myers, where afternoon thunderstorms roll in with 30 mph gusts, this shows up fast when the seal goes.
• The frame shows visible cracking or the window is hard to close after a storm. This can indicate frame warping or impact damage that may require a full unit replacement rather than a parts swap. If you see this, we should look at it before the next storm season.

Replacement Cost & What’s Included

CWS window replacement in Fort Myers pricing breaks down like this for the most common scenarios:

• Balance or lock replacement: $90-$180 installed, depending on the series and whether both sashes need new hardware.
• Insulated glass replacement in existing sash: $300-$520 per window, depending on glass size and low-E/impact specifications.
• Full sash replacement: $450-$700 per sash, matched to your existing frame and CWS series.
• Complete window replacement (frame and sash): $700-$1,400 per window installed, with the spread driven by size, impact rating, and frame material.

Every estimate is written and line-itemed, so you see parts cost, labor cost, and any disposal or permitting fees separately before you say yes. No change orders, no “we found something once we got in there” upcharges. If it’s not on the estimate, you don’t pay for it. And every CWS replacement we install carries Ed Winslow’s 36500-Day Done Right Promise: if it’s not done right, we make it right.

Standing discounts apply to this work: $40 off any repair over $200, and 10% off for seniors and veterans. Those aren’t promotions. They’re just how we price, year-round.

DIY or Call Us?

There are safe things to check yourself. A window that’s gotten harder to open may just need the tracks cleaned. Salt air leaves a fine film on vinyl tracks that builds up surprisingly fast in Fort Myers, and a damp cloth with mild detergent can clear it. You can also check whether the weatherstripping is visibly cracked or peeling, which tells us a lot before we even arrive.

Beyond that, we’d recommend against DIY on CWS units. The balance systems are under constant tension, the sashes are heavier than they look, and getting a glass replacement wrong in a hurricane zone is a mistake you don’t discover until the storm comes. We’ve fixed enough botched DIY jobs around Fort Myers to say plainly: these windows are not the place to save a hundred dollars. Call us at (239) 453-7751 and we’ll give you an honest assessment, free estimate, and no obligation.
