CWS Windows & Doors in Miami, FL | Winslow Windows & Doors
Winslow Windows & Doors provides independent CWS window and door service across Miami, from Hialeah to Little Havana to the Upper East Side. We’re not a factory-authorized agent, and we’re upfront about that. What we are is a local crew that knows CWS frame geometry, Miami-Dade’s NOA inspection process, and what salt air does to aluminum. If you need a repair, a full replacement, or a second opinion on a written estimate, call (727) 860-0593.
Why Miami Residents Choose Us for CWS Service
Ed Winslow grew up in Brownsville, spending weekends helping his grandfather fix up old CBS homes near Roberto Clemente Park. That’s where he learned to respect Miami’s particular brand of stubbornness: concrete block walls, 80% humidity, and Impact Windows - Miami homes know take a beating from June through November. We’ve serviced CWS window and door systems across Miami-Dade for years, building deep familiarity with CWS frame profiles, weatherstripping, and impact-glass integration – strictly as an independent service provider. We stock commonly replaced CWS parts so most Miami repairs don’t wait on a distributor. The work carries Ed’s name. He likes to say, “My name’s on the truck. That means something.”
Since 2011, we’ve been the local alternative to the national chains that hand you a ticket number. With Winslow, you get a live person on the phone, background-checked technicians in uniform, and upfront pricing with written line-item quotes. The Done Right Promise backs every CWS repair and installation we do in Miami. If it’s not done right, we make it right.
Common CWS Windows & Doors Problems We Solve in Miami
- Salt-driven corrosion on CWS aluminum frames and hinge hardware. Within about two miles of Biscayne Bay, the salt-laden air accelerates galvanic corrosion on aluminum frames, stainless hinges, and fasteners. We see CWS 760 single hungs with pitted frames and seized rollers in neighborhoods like the Upper East Side and Edgewater. The fix is often new corrosion-resistant hardware, but when the frame itself is structurally compromised, replacement is the honest recommendation.
- Failed interlocking weatherstripping on CWS horizontal rollers. Miami’s repeated storm-driven wind loads flex the meeting rails on CWS 780 horizontal rollers until the interlocking weatherstripping loses its grip and water intrudes at the center. Homeowners in Westchester and Flagami notice puddles on the sill after a heavy squall. We replace the interlock and realign the sash so the two halves seat tight again.
- Loss of argon gas and internal fogging in older CWS insulated glass units. Miami’s average humidity above 75% pushes moisture through failed butyl seals in aging CWS IGUs, leaving permanent condensation between the panes. Once the seal fails, the insulating value is gone. We replace the IGU, and if the frame still carries a valid Miami-Dade NOA number, the repair passes inspection without a full window swap.
- Stripped adjustment screws and sagging sashes on CWS single hung balances. Daily use in humid, salty air eats the threads on old adjustment screws. The sash sags, the balance cord slips, and the window won’t stay open. It’s one of the most common CWS repairs we perform across Miami, and it’s usually straightforward: new balance springs, new screws, and a re-lubrication with a corrosion-resistant compound.
- Water intrusion at CWS thresholds on sliding doors after seal failure. Miami’s afternoon downpours reveal weak threshold seals fast. On CWS 990 multi-slide doors, a worn threshold gasket turns a 20-minute storm into a wet living room. We replace the gasket, verify the weep holes are clear, and check that the door frame is still anchored solidly into the concrete slab.
CWS Service in Miami: What Local Conditions Mean for Your Equipment
Miami-Dade County’s product-approval system requires every CWS window and door we install to show a unique Notice of Acceptance (NOA) number, not just a Florida Building Code approval. So before any permit inspection, we verify the specific CWS model against the county’s online NOA database. Contractors who skip this step get automatic rejections and a re-order that adds weeks to the job. We don’t skip it. Off Northwest 32nd Avenue in Hialeah, our crew handling our Window Installation in Miami swapped a corroded CWS 760 single hung for a new NOA-approved 780 horizontal roller in a 1960s CBS bungalow. The old jalousie had been letting wind-driven rain soak the interior sill for months. The homeowner had already been rejected on a previous permit because another crew showed up with a statewide-approved product that lacked its Miami-Dade NOA number. We pulled the correct NOA, anchored new buck frames into the concrete block with stainless Tapcons, and flashed the masonry opening before setting the new impact unit. That’s the difference between knowing Miami-Dade and just working here.
CWS Models & Products We Service in Miami
We service the full CWS lineup across Miami, including the 760 Series Impact Single Hung, 780 Series Horizontal Roller, 550 Series Awning, and 990 Series Multi-Slide Door. For repairs, we stock commonly replaced parts locally: balance springs, rollers, corner keys, and weatherstrip profiles. When specific frame geometry or finish demands it, we source genuine OEM components. Our repair-versus-replace judgment is straight: if the frame holds, we repair. If the CWS frame shows structural corrosion or the glass no longer meets Miami-Dade NOA impact standards, we recommend full replacement, and we’ll show you why in writing.

We also handle CWS sales & service beyond the immediate city limits.
CWS Service Pricing in Miami
Most CWS repairs in Miami land between $180 and $340 for straightforward work: balance replacements, roller swaps, weatherstripping, threshold gaskets. Glass replacement, especially on impact-rated units, runs higher – typically $500 to $900 per pane depending on the CWS model and NOA compliance needs. Full CWS window replacement in Miami generally falls between $900 and $2,500 per opening, driven by frame condition, impact rating, and the masonry anchoring required on concrete block homes. Every free estimate includes a written line-item quote. No change orders unless you change the scope. Call (727) 860-0593 for an exact number – estimates are free, and we don’t charge a trip fee inside our home county.

FAQs - CWS Windows & Doors in Miami
Yes. Every window and door installed in Miami-Dade must carry its own unique Notice of Acceptance number that matches the county’s online NOA database. A Florida Building Code approval alone will not pass. We verify the exact CWS model number before any permit inspection so you don’t get a rejection letter. Call (727) 860-0593 if you’re unsure whether your existing CWS frames still meet current NOA standards.
The frame decides. If the aluminum is structurally sound – no deep corrosion, no cracking at the corners, no separation from the buck – repair is usually cost-effective. In Miami, the main frame killer is salt corrosion near the Bay. If the frame shows pitting that compromises the anchor points, we’ll tell you straight: it’s time for replacement. We never push replacement on a frame that still has life, because Ed’s name is on the work.
Almost always, it’s the interlocking weatherstripping at the meeting rail. Miami’s wind-driven rain pushes water against that center seam, and once the weatherstrip loses its compression, water wicks inside. A worn interlock or a misaligned sash makes it worse. We replace the weatherstrip, realign the sashes, and check the weep system – the three fixes that stop most CWS 780 roller leaks. Call (727) 860-0593 and we’ll diagnose it before the next storm.
Glass replacement is possible when the frame and sash still carry a valid Miami-Dade NOA number. We replace the IGU, re-glaze to the original CWS spec, and the window keeps its impact rating. If the sash itself is corroded or the NOA has lapsed or been superseded, a new sash or full unit is the only way to pass inspection. We’ll explain which applies to your specific CWS model before any work starts.
Yes. Miami-Dade requires a permit for window and door replacement, and the county cross-checks every product against the NOA database at inspection. We pull the permit, we verify the NOA numbers, and we schedule the inspection. It’s part of the job, not an add-on. Call (727) 860-0593 and we’ll walk you through the whole process.
