Why Marathon Residents Choose Us for CWS Service

We have been rebuilding and replacing CWS frames across Florida for years, but Marathon reset our standard for what passes a job. The wind-load rules here require Miami-Dade Notice of Acceptance paperwork on every impact opening, and Monroe County inspectors check load path, not just glass rating. A CWS 8500 impact casement that passes in Fort Myers might fail a Marathon permit if the elevation zone wasn’t split correctly. We know the difference. Dale Kessler grew up in Kendall and has been measuring, sourcing, and setting windows and doors in South Florida for going on three decades, including Coral Gables Cws service work. He still measures every job himself. The rule on our whiteboard hasn’t changed: measure it right the first time, or plan on coming back.

We are local to Marathon service area. Our technicians know that a 1973 CBS house on 62nd Street Gulf side likely still has original jalousie openings, that the north facade sits under different code than the south, and that the salt here comes at every elevation from two directions. We hire local, train apprentices into journeymen, and we answer the phone with a live person 24 hours a day.

Common CWS Windows & Doors Problems We Solve in Marathon

• Corner weld pitting on CWS 9400 Series aluminum frames. Marathon’s omnidirectional salt spray from Florida Bay and the Atlantic eats aluminum frame rail corners within 8 to 12 years. We see blistering and electrolytic pitting on both elevations, not just the side facing the street. This is the most common CWS failure here, and it usually starts at the weld.
• Fogged IGUs on north-facing CWS fixed windows. Coral limestone bounces UV and humidity from both bays, so sealed units on north walls fog within 5 to 7 years even when the panel never gets direct sun. The argon leaks out, condensation forms between panes, and the glass looks cloudy from the inside. We replace the IGU with OEM glazing.
• Roller and track binding on CWS sliding glass doors. Fine coral dust and marine grit build up inside stainless tracks faster here than anywhere on the mainland. Sweeping never clears it. We routinely disassemble tracks, ultrasonic-clean them, and replace frozen rollers so the door slides instead of dragging.
• Failed retrofit of a CWS impact unit into an original jalousie opening. Pre-2010 jobs often left a half-inch masonry gap filled with spray foam. Monroe County inspectors now flag and reject those on permit close-out. We pull the unit, cut the block correctly, and re-set the frame with the proper load path.
• Worn multi-point lock hardware on impact doors. Salt corrosion accelerates wear on CWS multi-point locks in Marathon. We replace with OEM stainless hardware because the NOA approval depends on original-spec parts.

CWS Service in Marathon: What Local Conditions Mean for Your Equipment

Marathon is the only city in Florida where the same home can have its south facade inspected under Miami-Dade HVHZ wind rules while its north facade falls inside the Florida Building Code’s coastal A zone. Monroe County’s permit routing depends on which side of the street the address sits on. That means a CWS replacement here cannot be a single NOA lookup. Every job we do includes a facade-by-facade design pressure calculation because failing to split the elevation zones is the most common cause of a Marathon permit rejection. If you live on the Gulf side of Key Vaca, your Atlantic-facing wall is not the same as your Florida Bay-facing wall under code, and your CWS units must be spec’d accordingly. Most mainland contractors - even those offering Cws service in Key West - don’t know this exists. It cost Dale an afternoon with the Monroe County building official to understand the routing, and it’s the first thing our techs check now.

CWS Models & Products We Service in Marathon

We service the full CWS lineup that matters in Marathon’s salt and wind environment: the 9400 Series fixed and casement windows, the 7700 Series single-hung and horizontal slider, the 8500 Series impact casement with Miami-Dade NOA, and the ES-5000 and ES-7000 impact sliding glass doors. On impact-rated units we install only OEM CWS glazing, IGUs, and multi-point lock hardware because aftermarket parts do not carry the NOA approval and can void the opening’s compliance. For non-impact interior trim and sash clips, a quality marine-grade aftermarket part works fine. If a CWS unit is older than 15 years in Marathon’s salt environment, we typically recommend full-frame replacement rather than repair. We stock OEM CWS parts locally for faster turnaround.

Services We Emphasize for Marathon Homes

Hurricane impact windows, full frame replacement, and wind mitigation and code compliance are the three jobs we do most on CWS units here. The 1950s through 1970s CBS homes that dominate Key Vaca were framed around slim jalousie profiles, so swapping those out for modern HVHZ-rated impact units almost always requires concrete cutting or block-infill work. That’s routine for us in Marathon.
