CWS Window Installation: The West Park Owner’s Guide

CWS window installation in West Park typically runs $340-$780 per opening depending on the series, glazing package, and whether the frame needs retrofit or full-frame replacement. We stock CWS-compatible hardware, sash packs, and full frame assemblies for same-day installation on most residential series found in Broward County. Most West Park homeowners discover a CWS window is failing when the sash won’t stay open, they feel air movement at the lock rail, or condensation appears between the glass lites of an insulated unit that was installed after 2010.

Which CWS Models This Applies To

CWS manufactures several residential series that have been specified in West Park homes since the mid-2000s, and the part you need depends on which extrusion system was originally installed. The most common we encounter are the CWS 300 Series single-hung and horizontal roller, the CWS 500 Series impact-rated line, and the CWS 7000 Series thermally improved frames used in energy-conscious retrofits near Sunview Park and the surrounding neighborhoods.

To identify your series, check the spacer bar between the glass panes or the edge of the sash for a stamped CWS logo with a four-digit date code. The 300 Series uses a 2-5/8 inch frame depth with a single weatherstrip groove; the 500 Series impact line runs 3-1/4 inches and carries a Miami-Dade NOA number that must match any replacement sash. The 7000 Series has a thermal break that visually separates the interior and exterior frame members.

We install both OEM CWS components and verified aftermarket equivalents that meet the original NOA specifications. For impact-rated units, we default to OEM sash and glass because the missile-impact certification travels with the exact glazing and frame combination; for non-impact replacement parts, a quality aftermarket balance system or lock mechanism often performs identically at lower cost. We document which route we recommend in your written scope before any work begins.

Signs Your CWS Window Installation Is Failing

• Sash drops or won’t stay open. The coil balance system has lost tension or the pivot bar has worn where it engages the balance shoe. In West Park’s salt-air environment, we’ve seen balance corrosion accelerate when windows face east and catch morning marine layer directly.
• Visible gap at the lock rail when latched. The sash has shifted in the frame due to worn hinge pivots or the frame itself has racked from settlement. We check plumb with a spirit level before quoting; sometimes the window is fine and the rough opening has moved.
• Fog or moisture between glass panes. The insulated glass unit (IGU) seal has failed, allowing humid South Florida air to enter the airspace. Once the desiccant saturates, the fog becomes permanent. IGUs cannot be resealed in the field; the glass pack must be replaced.
• Crank handle spins without moving the sash. On CWS casement and awning units, the operator gearbox has stripped internally, usually from over-torquing or lack of lubrication. The operator arm may also have detached from the sash bracket.
• Water intrusion at the sill during heavy rain. The weep holes are blocked with debris, or the sill flashing was never properly integrated with the WRB during original installation. We clear and test weep function during every service call; if the frame is back-pitched, the fix is structural, not cosmetic.

Replacement Cost & What’s Included

For CWS window installation in West Park, our installed pricing breaks down as follows:

What drives the range: frame condition (retrofit vs. full-frame), impact rating requirements, glass options (Low-E, laminated, tempered), and whether the opening needs new sill pan flashing. Every quote is a written line-item scope under Haven Clause 1; the measured survey you receive before work starts and the final invoice are the same document. No change orders. The 365-Day Done Right Promise covers all labor, and manufacturer defects are handled through CWS directly.

DIY or Call Us?

There is no high-tension spring or electrical hazard in standard CWS window service, but there is a precision hazard. A sash removed without proper support can drop and shatter laminated glass; an impact-rated IGU mishandled loses its missile-certification the moment the edge seal is compromised. We have replaced more than one homeowner’s “almost fixed” window where the balance was installed backward or the sash was forced into a racked frame.

What you can safely check: verify weep holes are clear, confirm the lock engages fully, and note any stamped markings for our reference. What we handle: sash removal, glass handling, balance tensioning, and frame plumb correction. We arrive with the correct CWS-compatible parts already on the truck, measured to your specific series.
