CWS Window Installation: The Hollywood Owner’s Guide
CWS window installation in Hollywood typically runs $340 to $720 per opening for standard retrofit replacement, depending on the series and whether the existing frame is preserved or replaced. We stock CWS-compatible hardware and installation kits for same-day starts on most jobs booked before noon. Most Hollywood homeowners discover their CWS window needs attention when the sash won’t stay open, the lock bar catches, or they feel Gulf Stream humidity pushing past weatherstripping that has flattened past recovery.
Which CWS Models This Applies To
CWS manufactures several series common in South Florida, and the installation approach differs by frame depth and mounting system. The CWS 312 Series uses a 2-5/8 inch frame depth with a nail-fin attachment meant for new construction or full-frame replacement. The CWS 5400 Series carries a 3-1/4 inch frame depth and is built for block-frame retrofit, which is what we encounter most often in Hollywood’s 1950s-1980s ranch and mid-century stock. The CWS StormStrong impact line adds laminated glass and reinforced interlocks, and its installation requires heavier-duty fasteners and specific shimming to maintain impact certification.
Identifying your series starts with the label. CWS stamps a white adhesive label on the top rail of the operable sash or the hinge side of a fixed unit. The label lists the NFRC ratings, the series number, and a manufacturing date code. If the label is gone, measure the frame depth from interior to exterior at a corner where the trim meets the vinyl. A 2-5/8 inch reading points to the 312; 3-1/4 inches indicates the 5400 or StormStrong.
We install both OEM CWS replacement units and compatible frames from our verified lines. For CWS specifically, OEM is the safer choice when the existing window is under 10 years old and the original color is still produced; CWS has changed its white vinyl formulation twice since 2015, and a 2025 frame next to a 2017 frame will read slightly different under Hollywood’s afternoon sun. Aftermarket equivalents work well when the opening is being fully retrimmed or the homeowner is repainting exterior anyway.

Signs Your CWS Window Installation Is Failing

- The sash drops or won’t stay open. This usually means the balance system has lost tension. CWS uses constant-force coil balances in the 312 Series and block-and-tackle balances in the 5400. In Hollywood’s salt-air environment, the balance shoes crack after 8-12 years, and the coil springs corrode where the window faces the Intracoastal or an unshaded east exposure.
- Visible daylight between the sash and frame when closed. The weatherstripping pile or bulb seal has compressed past its design recovery. CWS specifies Santoprene or dual-durometer vinyl seals depending on the year; once the compression set exceeds 30%, air and water bypass the seal regardless of how hard the lock is turned.
- Lock bar won’t engage or requires shoulder pressure. The keepers have shifted due to frame racking, or the lock mechanism itself has worn where the zinc die-cast cam meets the keeper. This is common in Hollywood homes where the original installation skipped shimming at the sill, allowing the frame to settle with the concrete slab.
- Condensation between the glass panes. The insulated glass unit (IGU) has lost its seal. CWS IGUs are warranted for 20 years by the manufacturer, but the installation warranty is separate. We document the seal failure with photos and verify whether the failure is covered under CWS’s glass warranty or requires a full replacement unit.
- Frame corners opening or vinyl chalking. The fusion-welded corners have stress-cracked, or the UV stabilizer in the vinyl capstock has degraded. South Florida’s UV index averages 9+ for six months of the year; CWS vinyl is rated for 10 years of exposure, but unshaded west-facing units often show degradation faster in Hollywood than in shaded inland locations.

AfterReplacement Cost & What’s Included
| Scope | Price Range (Hollywood) | What’s Included |
|---|---|---|
| CWS 312 Series, retrofit (frame preserved) | $340 - $520 per opening | Removal, new unit, balance hardware, interior/exterior trim seal, disposal |
| CWS 5400 Series, full-frame replacement | $480 - $720 per opening | Full frame removal, new frame, fasteners, insulation, trim, disposal, photo record |
| CWS StormStrong impact, full-frame | $620 - $890 per opening | Impact-rated unit, Miami-Dade HVHZ fasteners, permit, inspection coordination, documentation |
| IGU seal failure (glass-only, if frame sound) | $180 - $290 per sash | Custom IGU order, installation, argon fill, edge seal verification |
The range depends on three factors: the series, the condition of the existing rough opening, and whether the exterior trim is being preserved or replaced. A 5400 Series install on a Hollywood home with original stucco and no moisture damage runs toward the lower end. If we open the wall and find compromised sill pan flashing or termite-damaged framing, the repair extends the scope and the price, and we document both with photos before proceeding. Every quote is the measured survey you keep; the final invoice matches it. Haven Clause 1.
The 365-Day Done Right Promise applies to all CWS installations. If the sash doesn’t operate smoothly, the lock doesn’t engage flush, or the weatherstripping compresses unevenly, we return and correct it. The promise is written into the Haven Standard, not offered as a courtesy.
DIY or Call Us?

There is one part of CWS window work that is genuinely dangerous: the removal of a large fixed picture unit or impact-rated sash. These weigh 80 to 140 pounds depending on the glass make-up, and the handling requires two people with suction cups and proper bracing. A dropped impact unit will shatter into a carpet of glass fragments that extends 15 feet. We have seen homeowners in Hollywood’s Oakridge neighborhood attempt this with a helper and a blanket; the resulting laceration and glass replacement cost more than the original install would have.
What you can safely check: the lock keeper alignment with a flashlight, the weatherstripping compression with a business card (it should drag slightly when pulled through a closed sash), and the balance shoe condition by tilting the sash inward on a double-hung. What goes wrong in DIY: ordering the wrong frame depth, failing to flash the sill pan correctly, and stripping the fastener holes in block construction where there is no wood to re-tap. Measure the opening, not your optimism.

FAQs
A properly installed CWS vinyl window lasts 15 to 22 years in Hollywood before major component failure, with the balance system typically the first to go at 8-12 years and the IGU seal following at 12-18 years on unshaded exposures. The frame itself degrades from UV and salt-air oxidation, which accelerates within two miles of the coast. Call (754) 714-7309 for an exact quote on replacement - estimates are free.
Balance systems, locks, and weatherstripping can often be repaired or replaced independently of the full unit, which runs $85 to $190 in parts and labor per component. IGU seal failures and frame corner cracks require full unit replacement; there is no field repair that restores the original performance spec. We stock CWS-compatible balances, locks, and weatherstripping on our trucks for same-day repair when the frame is sound. Call (754) 714-7309 for an exact quote - estimates are free.
A standard retrofit replacement takes 2 to 3 hours per opening; a full-frame replacement with trim repair takes 4 to 6 hours. Most Hollywood homes with 8 to 12 openings are completed in one to two days, depending on the exterior finish work. We do not promise same-day completion on full-frame jobs; the sill pan and insulation need proper cure time before trim goes back. Call (754) 714-7309 to schedule your measured survey.
We stock CWS-compatible balances, lock sets, weatherstripping kits, and installation hardware for same-day repair starts. Full CWS replacement units are ordered to the measured rough-opening dimensions after survey; lead time is typically 5 to 10 business days for standard white vinyl and 3 to 4 weeks for custom colors or StormStrong impact units. We also stock and install PGT, CGI, and ES Windows lines if the opening requirements or budget point toward a different manufacturer. Call (754) 714-7309 to confirm availability for your series.
