How CWS Products Fail - and How We Fix Them

CWS windows are solid performers in South Florida, but after a decade of Miami Shores heat, humidity, and salt air, certain failure patterns show up repeatedly. Here’s what we actually see on service calls, and what we do about it:

• Seal failure on CWS Series 7000 insulated glass units. The Series 7000 line is common in Miami Shores homes built or renovated in the early 2000s. After ten to fifteen years, the desiccant inside the spacer bar saturates from constant humidity cycling, and the glass fogs between the panes. That fog means the argon or krypton fill is gone, and the window’s U-factor has quietly climbed. We replace the IGU with an Energy Star rated unit, and we verify the frame’s drainage channels are clear before we set the new glass so the same moisture problem doesn’t come back.
• Worn compression weatherstripping on CWS 8100 casement windows. Casement windows seal by compressing weatherstripping against the frame when the crank closes. In Miami Shores, that rubber gets brittle from UV exposure and salt spray faster than inland. You’ll feel air moving around the sash edges on a windy day, or see your AC bill creep up in August. We replace the weatherstripping with an aftermarket EPDM that has a tighter cell structure than the original, which actually improves the window’s air infiltration rating.
• Low-E coating degradation on south-facing CWS fixed picture windows. We’ve seen Low-E coatings on CWS windows facing Biscayne Bay start to show a slight haze or rainbow effect after extended direct sun. That’s the metallic oxide layer breaking down. The fix is a new IGU with a newer-generation low-E coating that reflects more infrared, and we always discuss whether a slightly darker tint makes sense for that exposure.
• Frame sealant failure at the CWS sill transition. The joint where the CWS frame meets the concrete sill is a weak point in a lot of Miami Shores installations from ten-plus years ago. The original sealant shrinks, cracks, or pulls away, and you get water intrusion that leads to higher indoor humidity and reduced insulating performance. We cut out the old sealant, address any rot or corrosion we find, and reseal with a marine-grade polyurethane that handles Miami’s rain and sun.
• Insulated laminated glass delamination on CWS impact-rated units. Some CWS impact windows pair laminated glass with an insulating air space. We occasionally see the laminate interlayer start to separate at the edges, especially on windows that get hammered by afternoon sun. That’s a safety and energy issue. We replace the glass package with a current-generation insulated laminated unit and recommend the right tint and low-E combination for your specific orientation.

Our CWS Energy-Efficient Windows Process

Every CWS job we do in Miami Shores follows the same path, whether it’s one window or twenty:

1. 1
   Call and talk to a person. You call (727) 483-7883. No voicemail, no dispatch service. We ask what you’re seeing, we listen, and we schedule a time that works.
2. 2
   On-site inspection and honest diagnosis. Our tech arrives in uniform, background-checked, and ready to look at the actual window. We test for air leaks, measure the glass, inspect the frame, and tell you what’s actually wrong - not what’s easiest to sell.
3. 3
   Parts decision: OEM or better aftermarket. CWS parts availability varies. When OEM is available and makes sense, we use it. When a proven aftermarket part outperforms the original - like the EPDM weatherstripping we mentioned - we tell you why and let you decide. We never install a part we wouldn’t put in Ed’s own house.
4. 4
   The repair or replacement. We do the work carefully, with proper flashing, clean seal lines, and square frames. Then we clean up. You won’t know we were there except for the improved window.
5. 5
   Test and verify. We check the seal, check the operation, and make sure the window closes and locks the way it should. When we leave, we both know it’s right.
6. 6
   The Done Right Promise. If it’s not done right, we come back and make it right. That’s not a marketing slogan. That’s how Ed has run this business since 2011.
