CWS Window Installation: The Tamiami Owner’s Guide

CWS window installation in Tamiami typically runs $340-$780 per opening depending on series, impact rating, and whether the frame is being replaced or retrofitted. We stock CWS-compatible hardware, sashes, and frame components for same-day repair on most Series 100, 200, and 5000 lines, and we carry the full CWS catalog for ordered replacement. Most Tamiami homeowners discover a CWS window is failing when the sash won’t stay open, the lock no longer catches, or they feel air movement around a frame that used to seal tight against afternoon thunderstorms.

Which CWS Models This Applies To

CWS manufactures three residential series that dominate South Florida installations: the Series 100 (single-hung, non-impact), Series 200 (single-hung, impact-rated), and Series 5000 (horizontal roller and fixed picture windows). The part you need depends on which series is in your wall.

Check the sash label first. CWS stamps a white adhesive tag on the top rail of operable sashes with the series number, manufacturing date, and Miami-Dade NOA reference. For fixed picture units, the label sits on the interior frame edge, visible when you open the adjacent operable sash. If the label is sun-faded, measure the frame depth: Series 100 uses 2-5/8 inch frames, Series 200 uses 3-1/4 inch frames for impact glass, and Series 5000 rollers run 3 inch nominal.

We specify OEM CWS parts for sash replacements and lock hardware because the tolerances are tight. For weatherstripping, roller assemblies, and balance shoes, we use quality aftermarket equivalents that meet the same Durometer and load specs at lower cost. The difference matters on a Series 200 impact unit where the sash weight exceeds 45 pounds; a generic balance shoe will fail within two seasons of Tamiami’s humidity cycle.

Signs Your CWS Window Installation Is Failing

• Sash drops or won’t stay open. The coil balance or block-and-tackle assembly has lost tension. In Tamiami, salt air corrodes the balance housing faster than inland markets, and we replace these on Series 100 and 200 units more often than any other component.
• Lock tongue won’t extend or retract. The multipoint lock mechanism has jammed from grit accumulation or the cam has worn. CWS uses a proprietary keep and tongue geometry; a standard replacement from the hardware store will not seat correctly.
• Visible gap at the meeting rail when closed. The sash has shifted on its balance shoes or the interlock weatherstrip has compressed permanently. This gap admits water during driving rain and costs cooling load every hour it stays open.
• Roller grinding or sash sticking on horizontal units. The Series 5000 roller assembly has flat-spotted or the adjustment screw has backed out. Tamiami’s limestone dust accelerates wear; we find rollers need replacement every 8-12 years on west-facing openings.
• Condensation between glass panes. The insulated glass unit (IGU) seal has failed. CWS IGUs are replaceable without changing the frame on Series 200 and 5000; Series 100 requires full sash replacement because the glass is glazed directly into the vinyl.

Replacement Cost & What’s Included

These prices include the part, labor, disposal, and our documented photo record. What drives the range: frame condition (rot or squareness), stucco repair extent, and whether the opening needs reframing to meet current Miami-Dade wind-borne debris codes. We pull permits when required and pass inspection before invoicing. Every repair carries the 365-Day Done Right Promise under Haven Clause 5: No surprises.

DIY or Call Us?

There is safe checking, and there is unsafe disassembly. A homeowner can verify the series label, photograph the failing component, and confirm the symptom. What we do not recommend: removing a Series 200 impact sash without proper support, adjusting multipoint lock cams with the glass under load, or attempting IGU replacement without vacuum lifting equipment. Impact glass weighs roughly 6-8 pounds per square foot; a 36-by-60 inch sash exceeds 90 pounds.

We stock CWS balance shoes, lock keeps, and Series 5000 roller assemblies on our Tamiami service vehicles. For IGUs and full sashes, we measure on-site and order to the documented specification.
