CWS Window Installation: The Fort Lauderdale Owner’s Guide

CWS window installation in Fort Lauderdale typically runs $340-$680 per opening for standard vinyl or aluminum replacements, with impact-rated CWS units landing at $890-$1,450 installed depending on size and glazing specification. We stock CWS-compatible frame extrusions, sash kits, and hardware for same-day repair on most series, and we carry the full CWS catalog for new installs ordered to measured spec. Most Fort Lauderdale homeowners discover their CWS window needs attention when the sash won’t stay open, they feel Gulf Stream humidity pushing through a failed weatherstrip, or they spot corrosion blooming on the weep-hole track after a wet season.

Which CWS Models This Applies To

CWS manufactures four residential lines we regularly see in Fort Lauderdale: the 300 Series single-hung vinyl, the 500 Series double-hung, the 7000 Series impact-rated aluminum, and the Targa by CWS impact line with Miami-Dade NOA certification. The 300 and 500 Series share a 2-5/8″ frame depth and use interchangeable balance shoes and tilt latches; the 7000 Series and Targa run a 3-1/4″ thermally broken frame with proprietary corner keys and impact-laminated glass beds that do not cross over.

To identify your unit, open the sash and look for the CWS etch mark on the glass spacer or the series sticker on the frame jamb. The critical measurement is the daylight opening - not the frame outside dimension - because CWS sizes its replacement sashes to the existing master frame. We have seen homeowners in Coral Ridge and Rio Vista order the wrong sash because they measured the brickmould instead of the jamb-to-jamb clear opening.

We are an independent service provider with no affiliation to CWS. We source OEM CWS parts through authorized distribution and stock quality aftermarket equivalents where the OEM lead time exceeds what Fort Lauderdale weather permits. For the 300/500 Series, aftermarket balances and keepers perform identically at lower cost; for 7000/Targa impact units, we specify OEM corner keys and glazing beads because the NOA depends on exact material certification.

Signs Your CWS Window Is Failing

• Sash drops or won’t stay raised. The coil balance has lost tension or the balance shoe is cracked. In Fort Lauderdale’s salt air, the galvanized balance housing corrodes faster than inland specs predict, usually showing failure between year 8 and 12.
• Visible moisture between glass panes. The insulated glass unit (IGU) seal has failed. CWS units from 2015-2019 used a dual-seal system that degrades faster when the weep holes are blocked by Fort Lauderdale’s heavy pollen and leaf debris.
• Frame corner separation or visible gap at the sill. The mechanical corner key has backed out or the vinyl weld has stress-cracked. South Florida’s thermal cycling - 90°F days, 75°F nights, months on end - fatigues the corner faster than northern climates.
• Hardware operates stiffly or the lock cam misses the keeper. The multipoint lock mechanism has shifted because the hinge-side screws have walked out of the vinyl jamb. This is common on west-facing CWS units in Victoria Park where afternoon expansion cycles loosen fasteners.
• Water stains on the interior sill after heavy rain. The sill track weep holes are clogged, or the exterior face sealant has separated from the frame. Fort Lauderdale’s driving rain from the southeast tests every installation detail within the first two wet seasons.

Replacement Cost & What’s Included

What drives the range: unit size, floor level (second-story carries ladder and scaffold time), and whether the existing frame is square within 1/8″ - CWS tolerances are tight, and a racked opening requires reframing. Every quote we write lists parts, labor, and disposal as separate line items under Haven Clause 1: the measured survey you keep and the written price match before any work starts. The 365-Day Done Right Promise covers all CWS work, and every completed job leaves a documented photo record of the opening before, during, and after.

DIY or Call Us?

There is one thing a CWS owner can safely check: the weep holes. Run a piece of stiff wire through the exterior sill slots and clear any debris - this solves about 15% of the water-intrusion calls we get in Fort Lauderdale. You can also verify the series sticker and measure your daylight opening with a tape measure; we will confirm your numbers before ordering.

Everything else carries real risk. CWS impact-rated units use tempered and laminated glass that weighs 4-6 pounds per square foot; a 36″ x 72″ Targa sash is roughly 75 pounds of glass and aluminum that can sever a finger or crush a foot if the balance releases unexpectedly. The corner keys on 7000 Series frames are under spring tension during assembly. We have replaced units where a homeowner cracked the IGU trying to force a tilt latch, then paid for the glass and the original repair. If you are not certain of the series, the balance type, or the glazing specification, call us. We stock CWS-compatible parts on every truck and measure twice before ordering once. Measure it right the first time or measure it twice on someone else’s dime.
