How CWS Products Fail - and How We Fix Them
CWS builds a solid window, but South Florida weather has a way of finding the weak spots. Here’s what we see most in Little Gables homes, and what we do about it.
- CWS Low-E seal failure (common on their insulated glass units): When the desiccant strip inside the glass unit saturates, you get that milky haze or condensation between the panes that never wipes off. The Low-E coating is still there, but the argon or krypton gas fill has escaped, so the window has lost a big chunk of its insulating value. We order a matching insulated glass unit with the correct Low-E coating and gas fill, pull the sash, swap the glass, and reseal it. Most CWS sashes make this a clean one-hour job.
- Fogging on the CWS 680 series in tile-roof homes: In Little Gables especially, brittle original sealant around the frame lets humid air work into the glazing channel from the outside. The glass fogs from the bottom edge upward, which most people mistake for an indoor humidity problem. We don’t just reseal the visible seam; we pull the sash, clean the glazing channel, replace the setting blocks, and re-bed the glass so water can’t wick back in.
- Warped or bowed sashes on wider CWS sliders: Wide CWS horizontal sliders can develop a slight curve over years of afternoon sun on west-facing walls. That bow breaks the weatherstrip contact at the meeting rail, and you feel the draft right at hand height. We replace the sash with the correct OEM-profile frame extrusion and upgrade the weatherstripping to a compression-seal profile that tolerates flex better than the original wiper-type seal.
- Faded tint and UV damage on original single-pane CWS units: Older CWS windows in Little Gables that predate the energy-code push often have basic tinted glass and no Low-E. The tint fades unevenly, furniture near the window bleaches out, and the glass gets hot enough to feel through closed blinds. We can pull the original glazing and drop in a laminated Low-E unit with UV-blocking interlayer, which cuts UV transmission to nearly nothing and brings the window up to current energy standards without replacing the whole frame.
- Failed locks and latches that leave the window slightly open: A CWS window that won’t compress fully at the lock rail is an energy leak even if you can’t feel a draft yet. On the twin-latch cam locks CWS used on many single-hung models, the nylon latch pawls wear down and the window drifts open a fraction of an inch. We replace the hardware with a more aggressive cam-lock set, adjust the keeper, and re-adjust the sash for full compression.
Our CWS Energy-Efficient Windows Process
- 1
Call and describe what you’re seeing: fog between the panes, a draft, a window that won’t lock down. A real person answers, day or night.
- 2
Diagnostics in your home: we inspect every sash, check the gas-fill status with a glass-thickness meter and visual condensation map, and identify which windows actually need work.
- 3
Parts decision: for warranty-sensitive or newer CWS installations, we order OEM CWS glass and hardware. For older out-of-warranty units, we may recommend a quality aftermarket insulated glass unit that matches the original aesthetic but carries better energy ratings.
- 4
The repair or replacement: we pull the sash, replace the glass and hardware, clean the frame, and re-seal with a South Florida-rated sealant that can take the heat and humidity.
- 5
Test: we run a smoke-pencil draft check around every sealed joint and verify the lock compression and open-closed travel before we call it done.
- 6
Cleanup and follow-up: we haul the old glass, sweep the sill, and you get a written work summary. If it’s not done right, you call and we come back. That’s the Done Right Promise.
What CWS Energy-Efficient Windows Costs in Little Gables
- Fogged CWS insulated glass replacement: $95-$260 per sash, depending on sash size and whether it’s a standard Low-E unit or a laminated glass upgrade.
- Full CWS window replacement (energy-efficient dual-pane): $900-$2,400 per window, including tear-out, install, trim, and haul-away.
- Weatherseal and hardware refresh on CWS sash: $85-$190 per window, parts and labor included.
What moves the price: window size, whether it’s a fixed panel or operating sash, local code requirements, and whether the frame itself is still square and sound.

Why Little Gables Homeowners Call Winslow Windows & Doors for CWS Work
Because we show up when we say we’ll show up, and we don’t leave until the window is right. Ed Winslow grew up in Little Gables, not far from the old Coral Gables Congregational Church, and he still lives within a few miles of where he learned to ride a bike. When you call, you’re not calling a national chain with a rotating crew; you’re calling a local company with a published address, a license number, and an owner whose name is on the truck. We’re an independent CWS service provider, which means we can be honest with you about what needs fixing and what doesn’t. And while CWS is what we’re talking about here, our techs also work on PGT, CGI, ES Windows, and ECO Window Systems every week, so if your home has a mixed lineup, one crew can handle it all. Every technician is background-checked and uniformed. The Done Right Promise backs every job: if it’s not done right, we make it right.
FAQs
That depends on the age of the window and the specific CWS warranty that was in effect when it was installed. Most CWS glass units carry some coverage for seal failure, but labor and installation are typically not covered after the first year. We can help you document the failure and determine whether a warranty claim makes sense before you spend anything on diagnostics.
You can often repair it. Fogged glass, failed weatherstripping, and worn hardware are all repairable without replacing the entire window, and we do that all the time for CWS homes. We’ll only suggest full replacement when the frame itself is compromised, the cost of the repair approaches the cost of a new energy-rated unit, or a window replacement makes more financial sense.
Most common CWS glass units and hardware parts arrive in our shop within 3 to 10 business days. We’ll give you a straight lead time when we place the order, and we’ll call you the day the parts land so you’re never left wondering what’s happening.
No. The price on your written estimate is the price on the invoice, and we don’t write change orders for standard work. If we find something unexpected behind the trim, we’ll stop, explain it, and get your sign-off before anything else happens. That’s the whole point of our no-hassle pricing.
Yes. We give $40 off any repair over $200, and seniors and veterans always save 10%. Those offers are permanent, not promotions; they’re part of how we do business here in Little Gables.
