CWS Windows & Doors in Miami, FL | Winslow Windows & Doors
We provide independent CWS windows and doors service across Miami, from Coral Gables to Little Havana and every CBS block in between. We’re not a CWS dealer or a manufacturer call center. We’re the crew Miami homeowners call when a CWS horizontal roller grinds, a single-hung sash slams shut, or an inspector flags a window that lost its wind mitigation credit. Here’s the thing most Miami homeowners don’t realize until inspection day: in Miami-Dade, a Florida Statewide Product Approval number alone will fail an inspection. Your CWS opening has to carry a Miami-Dade Notice of Acceptance specifically, and we check that paperwork before the first cut. Call (844) 901-4551 for a free estimate on CWS service in Miami.
Why Miami Residents Choose Us for CWS Service
Ed Winslow grew up in Hialeah, watching crews work the older concrete-block homes west of the Palmetto Expressway. That’s where the curiosity about how buildings actually hold together first took root. He went through the construction technology program at Miami Dade College’s Wolfson Campus, then spent years in the field learning what textbooks leave out. For well over a decade, we’ve focused exclusively on windows and doors in South Florida, and CWS has been part of that work since the 2000s.
Miami homeowners call us because we know CWS hardware the way a mechanic knows a specific engine. We stock CWS-specific interlock assemblies, roller kits, and corner key hardware. When OEM parts are discontinued, we source Miami-Dade-approved equivalents and document the substitution so your NOA stays intact. We’re locally owned by Ed Winslow, our address and license number are published, and every technician who shows up at your door is background-checked and in uniform. You’ll know exactly who’s walking up your driveway before the truck stops.
And yes, a live person answers our phone 24/7. No voicemail loops. No call center in another state. Call (844) 901-4551 and someone on our team picks up.
Common CWS Windows & Doors Problems We Solve in Miami
- Seized roller assemblies on CWS 6750 horizontals. Salt-laden air off Biscayne Bay corrodes the stainless rollers and housings even when the interlock looks clean from the outside. The sash gets heavy, then it won’t slide at all. We replace the rollers, clean the tracks, and test the full travel so the window glides again.
- Weep hole blockage from wind-driven sand and salt crust. In older CWS 6750 tracks, blocked weep holes trap water inside the frame. You won’t see it until the stucco below starts staining or the frame corners show rot. We clear the weep system, check the interior track for concealed corrosion, and reseal where the salt has eaten through.
- CWS single-hung coil balances losing tension. High-humidity thermal cycling in Miami puts constant stress on the original coil balances. After a few seasons, the sash won’t stay up and slams shut hard enough to crack the glass or pinch a hand. We replace the balance assemblies and adjust the shoe so the sash holds at any height.
- Silicone bead separating at aluminum frame corners on pre-NOA CWS units. Older CWS windows that predate Miami-Dade NOA requirements often show silicone failure at the corners. Water gets behind the fin and rots the stucco around the opening. We cut out the failed bead, inspect the flange, and reseal with a marine-grade product rated for our salt environment.
- Lost insurance wind mitigation credits after a repair with wrong parts. This one’s specific to Miami. A homeowner replaces a CWS roller with an aftermarket part that voids the product approval. The insurance wind mitigation credit disappears. We document every component we install and keep your Miami-Dade NOA intact, because we know that credit is worth real money on your premium.
CWS Service in Miami: What Local Conditions Mean for Your Equipment
Here’s what separates Miami from every other Florida market, and it’s not subtle. Miami-Dade County is a High Velocity Hurricane Zone. Every replacement window and door in your home has to carry a Miami-Dade Notice of Acceptance, a product-testing protocol stricter than Florida’s statewide approval system. A CWS window that’s perfectly legal and inspectable in Tampa or Sarasota will fail a Miami-Dade inspection if it doesn’t have the NOA paperwork. So before we order a single part or cut a single frame, we confirm the product approval. We’ve seen out-of-market crews learn this the hard way at inspection, standing in a homeowner’s living room while the inspector shakes his head. We check the sticker, verify the series, and document everything before the work starts. That’s not extra service. In Miami, it’s the baseline. And it’s why our CWS work here is fundamentally Impact Windows — Miami compliance conversation, not just a repair call.
Take the CWS 9200 Series casement, for example. The NOA covers specific hardware combinations. If we replace a hinge arm with a part that wasn’t part of the tested assembly, technically the window no longer matches its approval. We don’t do that. We match OEM hardware to the exact series and year, and if OEM is gone, we source a Miami-Dade-approved equivalent and note the substitution in writing. Your inspection passes, your insurance credit stays, and your window actually works.
CWS Models & Products We Service in Miami
We service the full CWS impact lineup you’ll find in Miami-Dade homes:
- CWS 7800 Series Single Hung Impact Window – common in CBS construction from the 1980s and 1990s, especially in neighborhoods like Little Havana and Hialeah.
- CWS 6750 Series Horizontal Roller Impact Window – the workhorse slider in older Miami remodels, and the series that gives us most of our roller and weep hole calls.
- CWS 9200 Series Casement Impact Window – popular on higher-end homes along the coast, where salt exposure demands stainless hardware.
- CWS 4500 Series Awning Impact Window – smaller openings, bathrooms and kitchens, where ventilation matters as much as impact rating.
We use OEM CWS hardware whenever it’s still stocked, especially the NOA-tested interlock and corner key assemblies. Aftermarket parts can void the product approval, and in Miami-Dade that means a failed inspection and a lost insurance credit. When OEM is discontinued, we source Miami-Dade-approved equivalents and document the substitution in writing. We recommend full replacement only when corrosion has compromised the structural flange or the glass is still single-pane and nonimpact. Our CWS sales & service work always starts with what’s salvageable, not what’s sellable.
CWS Service Pricing in Miami
Most CWS repair work in Miami falls into a predictable range, and we quote it upfront before any work begins. Roller replacement on a CWS 6750 horizontal typically runs $180 to $340 per window, depending on how far the corrosion has spread into the track and housing. Coil balance replacement on a single-hung runs $150 to $280. Weep hole clearing and frame resealing runs $120 to $250 per opening. A full NOA verification and documentation for a wind mitigation inspection runs $95 to $200, which pays for itself the first time your insurance premium drops. Every estimate is free, every quote is line-itemed, and we don’t change the number once we start. Call (844) 901-4551 for an exact quote on your CWS windows in Miami.

FAQs — CWS Windows & Doors in Miami
Many older CWS windows in Miami do not carry a current Miami-Dade NOA, especially units installed before the HVHZ designation tightened in the early 2000s. We verify the NOA sticker and match it to the current Miami-Dade product approval database before any work begins. If your windows are NOA-compliant, we document it for your insurer. If they’re not, we’ll tell you honestly what replacement costs and what credit you’re leaving on the table. Call (844) 901-4551 and we’ll check your windows during a free estimate.
It depends on the unit and how the glass is set. Some CWS impact windows use a structural silicone glazing bead that allows for glass-only replacement while preserving the original frame and NOA. Others use a wet-glazed system where the glass is bonded to the sash, and replacing just the glass means compromising the tested assembly. We’ll assess your specific CWS series and tell you the truth about what’s possible without voiding your Miami-Dade approval. Call (844) 901-4551 for a free inspection.
It’s usually both. Salt air from Biscayne Bay corrodes the roller bearings, and the resulting metal shavings grind into the track, scoring the aluminum. Replacing only the rollers leaves a rough track that wears out the new rollers in months. We replace the roller assemblies, clean and dress the track, and lubricate with a marine-grade product that holds up to Miami’s salt exposure. Call (844) 901-4551 to schedule a roller replacement estimate.
CWS does not sell parts directly to the public. Homeowners in Miami generally have to go through a dealer or service provider who has accounts with CWS distributors. We stock CWS hardware for the 7800, 6750, 9200, and 4500 series, and we source OEM parts directly through CWS distribution channels. When OEM is discontinued, we use Miami-Dade-approved equivalents and document the substitution for your inspection file. Call (844) 901-4551 with your CWS model number and we’ll tell you what’s available.
In Miami-Dade, generally no. Impact rating isn’t just about the glass. It’s the entire tested assembly, frame, glass, interlock, and hardware. You can’t retrofit a non-impact CWS window to impact status and keep it legal under HVHZ code. What you can do is install impact-rated CWS windows with a current Miami-Dade NOA, and we’ll walk you through our Window Installation in Miami from permit to final inspection. Call (844) 901-4551 for a free replacement estimate.
