CWS Windows & Doors in Key West, FL | TruePane Windows & Doors
TruePane Windows & Doors is an independent CWS service provider serving Key West and the Lower Keys, with Cws service in Key Colony Beach also available. We repair and replace CWS Series 8000 single-hungs, 7300 sliders, Architectural casements, and legacy storm panels across the island. The work that separates us here comes down to one thing: we know how to get a CWS impact window past HARC and Monroe County code on a contributing Conch house without stalling the job for months. Call (813) 320-9346 for a straight answer on your CWS equipment.
Why Key West Residents Choose Us for CWS Service
Dale Kessler founded TruePane in 2008 after years of seeing out-of-true installs and voided warranties on Florida window jobs. He grew up in a family that did building maintenance, so a callback was never just an inconvenience. It was a character flaw. That standard governs how we handle CWS work in Key West.
We stock original-spec CWS extrusions and replacement hardware for the model lines that ended up in Key West’s Conch cottages and 1980s to 2000s frame homes. We have pulled hundreds of HARC and Monroe County permits specifically for CWS impact retrofits on contributing structures. That experience means we know which CWS frames can pass a HARC visual inspection and which ones will get rejected before you spend money on the wrong unit.
Every job carries our 90-Day Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing before our truck leaves your driveway. If the pane is not true, the job is not done.
Common CWS Windows & Doors Problems We Solve in Key West
- Salt-spray pitting on CWS aluminum frames. Homes along Duval and Simonton Streets deal with relentless salt air that causes white chalky oxidation on pre-2000 CWS Series 8000 units without a clear-anodized marine finish. The sash locks up, and the oxidation only spreads. We assess whether the frame is worth saving or ready for full replacement.
- CWS jalousie installations failing wind mitigation. Old Conch houses still carry louvered CWS jalousie windows. They leak at the louver pivot points, and insurance carriers increasingly refuse to cover them. We swap to sealed impact units that pass Monroe County wind mitigation and get your policy renewed.
- Clogged screen tracks on elevated homes. Coral dust and salt crystals pack into original CWS screen tracks on Old Town pier houses. Sashes bind, then bend the operator arms on CWS casements. We clean the tracks, replace bent operators with OEM parts, and set the sash true again.
- Corroded storm panel hardware. CWS storm panels stored under raised Key West homes never get reinstalled until a storm approaches. The stainless pins corrode, and the panels will not seat. We replace the hardware with marine-grade 316 stainless and test the fit before hurricane season.
- Impact glass damaged by flying debris. Post-storm, we see a repeat sight across Key West: coconut and zinc roof debris punching through CWS impact glass. The glass held, but it is compromised. We measure, order OEM replacement sashes, and get the opening sealed properly.
CWS Service in Key West: What Local Conditions Mean for Your Equipment
Key West is the only city in the United States where a building permit for a CWS impact window swap cannot be issued until HARC confirms the new frame’s muntin profile matches the original Conch-style wood or metal windows. A code-compliant CWS Series 8000 with grille-between-glass will not clear that review on a contributing structure. HARC wants true divided lites and period-correct hardware. That review can stall an otherwise approved swap for four to six weeks while a custom CWS Architectural true-divided-lite casement is fabricated.
For a homeowner on Eaton Street or William Street, that means the contractor you pick has to understand both sides of the counter, much like our team offering Cws service in Coral Gables. We do. We have pulled HARC permits alongside Monroe County building permits on hundreds of CWS jobs in Old Town. We know when to spec a CWS Architectural casement instead of a Series 8000, how to match a white bronze finish to original porch wood, and how to sequence the paperwork so neither review holds up the other. Out-of-town crews assume a Florida impact label is the only approval they need. They learn otherwise when the commission rejects their submittal.
CWS Models & Products We Service in Key West
Our crews work on the CWS lines that actually landed in Key West homes: Series 8000 single-hung, Series 7300 sliding patio doors, Architectural casements with true divided lites, and legacy accordion and bifold storm panels. We use OEM CWS hinges, operators, and weatherstripping because Key West’s salt air destroys generic aluminum after a single hurricane season. Where OEM parts underperform, we say so plainly and spec better: nylon-sleeved CWS lock backcheck springs get swapped for marine-grade 316 stainless replacements.
For any CWS frame older than 20 years, or one showing visible oxidation on the bottom rail, we recommend full-frame replacement over gasket patching. The money goes further before the next salt season.
CWS Service Pricing in Key West
Key takeaways on cost:
- Service call and diagnosis: $89, applied toward the repair if you proceed.
- Hardware replacement (operators, locks, weatherstripping): $175 to $475 depending on the CWS model and the extent of salt corrosion.
- Full impact window replacement on a standard Conch house opening: $2,200 to $6,500 per unit, depending on whether HARC requires a custom true-divided-lite CWS Architectural casement.
- Sliding patio door service: $250 to $900 for roller and track work; full replacement ranges higher by model and size.
The HARC layer is what shifts CWS pricing in Key West versus other Florida cities. A standard Series 8000 impact unit passes code but fails preservation review on contributing structures. A custom CWS casement built to match original muntin profiles costs more and takes longer. We give you both numbers side by side on paper before you commit. Estimates are free. Call (813) 320-9346 and we will walk the job with you.

FAQs - CWS Windows & Doors in Key West
No. HARC requires true divided lites and period-correct hardware on contributing structures in Old Town, so a standard CWS impact window with grille-between-glass will not pass visual review. We spec a CWS Architectural true-divided-lite casement with the correct muntin profile and finish. Call (813) 320-9346 and we will tell you which CWS frame passes on your street before you order anything.
Jalousie windows, regardless of brand, do not meet Monroe County wind mitigation requirements. The louvered glass panels cannot handle 180+ mph design loads, and insurance carriers have been non-renewing policies on homes that still carry them. We replace CWS jalousie units with sealed impact windows that satisfy wind mitigation and get your coverage reinstated. Call (813) 320-9346 for a free estimate.
Sometimes. If the rollers and track are worn but the frame is sound, we replace the rollers, clean the track, and set the door true again. If the bottom rail shows salt corrosion or the frame has bowed from years of marine exposure, repair money is wasted. We will say so plainly either way. Call (813) 320-9346 for a straight assessment.
HARC review applies only within the Historic District boundaries, which cover much of Old Town, while our Cws service in Homestead covers areas outside the Keys. Homes in New Town and other areas outside the district do not need HARC sign-off, but they still need Monroe County building permits and wind mitigation compliance. We tell you exactly which reviews your address triggers before we start.
The bottom rail and weep holes fail first. Salt spray settles on the frame, packs the weep holes, and traps moisture inside the extrusion. Within a few years the rail swells, the sash locks, and the oxidation spreads. It happens faster on CWS frames without a clear-anodized marine finish. We inspect the bottom rail first on every salt-front CWS call. Call (813) 320-9346 and we will tell you what your frames are doing before they fail.
