How CWS Products Fail - and How We Fix Them

• CWS 3120 Series horizontal rollers: The stainless steel tandem rollers seize in Cutler Bay’s salt-air environment, typically within 6-8 years of install. We see this most often in Lakes by the Bay and other waterfront-adjacent sections where the coastal humidity accelerates corrosion beyond what the OEM grease specification handles. We replace with marine-grade sealed bearings and document the frame squareness before reinstallation. If the opening isn’t square, no amount of caulk makes it right.
• CWS single hung impact windows (standard and high-rise configurations): Balance shoe failure presents as a sash that won’t stay open or slams shut uncontrolled. The cause is usually a worn cam pivot or a balance tube that has lost nitrogen pressure after repeated hurricane-season cycling. We stock both OEM CWS balance assemblies and verified aftermarket equivalents rated to the same 50 PSF design pressure, and we test every repaired sash through ten full open-close cycles before leaving.
• CWS vinyl frame corner separation at the weld: This shows up as visible daylight at the frame corner or interior water staining after heavy rain. The root cause is often thermal expansion stress on openings that face west or south without adequate overhang protection, which is common in Cutler Bay’s 1980s-2000s ranch homes. We assess whether the frame is salvageable; if not, we specify a replacement unit with reinforced corner construction and document the rough opening condition in the photo record.
• CWS impact door multipoint lock misalignment: The shootbolts and deadbolts fail to engage cleanly, leaving the door latched but not secured. This typically traces to frame settlement or hinge wear rather than lock mechanism failure. We measure the active sash drop, shim the frame to true plumb, and only replace hardware when the alignment data supports it. Many Cutler Bay homes built on the area’s oolitic limestone substrate experience minor seasonal settlement that repeats the problem if you only swap the lock.
• CWS laminated glass delamination (impact-rated units): The interlayer clouds or bubbles at the edge, visible when light hits at an angle. This is not a seal failure; it’s moisture ingress at the glass edge where the polyvinyl butyral has degraded. In Cutler Bay, we see this accelerated on units installed before 2015 that lacked the improved edge deletion specified in current CWS fabrication standards. We source replacement IGUs with the updated edge treatment and verify the glazing pocket drainage before setting the new unit.

Our CWS Impact Windows & Doors Process

1. 1
   Measured survey. We arrive with the CWS product catalog for your series and year, record rough opening dimensions to 1/16 inch, photograph existing conditions, and note any frame distortion or water staining. You keep a copy of this survey.
2. 2
   Written scope and price. The measured survey becomes the quote. We specify OEM or verified aftermarket parts by part number, list the labor hours, and stamp the total. This document does not change unless you change the scope.
3. 3
   Parts procurement. For discontinued CWS series, we source from our verified aftermarket network or cross-reference to compatible PGT, CGI, or ES Windows hardware when the engineering data supports it. We never substitute without written approval.
4. 4
   Installation and testing. We remove, repair or replace, and test every operable sash for smooth function, every lock for full engagement, and every impact-rated unit for visible glazing integrity. The crew chief signs the test checklist.
5. 5
   Documentation and closeout. You receive the completed photo record, the signed test checklist, and the 365-Day Done Right Promise certificate referencing Haven Clause 5: No surprises. Payment is due only after you review and accept the documentation.
6. 6
   Follow-up. We call at 30 days to confirm operation and schedule any needed adjustment under the Promise. No charge, no expiration on that call.
