CWS Windows & Doors Service Nationwide | Winslow Windows & Doors

Why Miami Shores Homeowners Choose CWS Windows & Doors

We provide independent CWS Windows & Doors in Miami Shores, FL service, from single-hung balance replacements to full-frame hurricane retrofits. Since 2011, Winslow Windows & Doors has worked on more CWS 6900 single hungs, 5900 horizontal rollers, and 6700 casements in Miami Shores than most crews see in a career, and we bring that model-specific knowledge to every job. We’re an independent service provider, never authorized by CWS, which means our recommendations come from what’s actually wrong with your window or door, not from a brand playbook. Call (727) 483-7883 and you’ll talk to a live person who knows CWS products.

Miami Shores is a different animal from the rest of Miami-Dade. The village sits right off Biscayne Bay, and that salt-laden airflow does a number on window hardware, especially on east-facing elevations. Combine that with the Architectural and Historical Review Board requiring every replacement to preserve the Mediterranean Revival character of the streetscape, and you need a contractor who understands both CWS mechanics and Miami Shores’ dual-compliance reality. That’s us. Ed Winslow grew up a few blocks from Barry University and has been installing and repairing windows in this village for the better part of three decades.

Why Trust Winslow Windows & Doors for Your CWS Windows & Doors?

CWS builds a solid product, but like any window or door in South Florida, it’s only as good as the install and the maintenance behind it. Our techs know CWS hardware inside and out because we see it every week in Miami Shores. We know which balance springs the 6900 Series uses, how salt air chews through 5900 roller assemblies, and why older 6700 casements trap water in their frames. That’s not catalog knowledge. That’s field knowledge.

Ed Winslow learned the trade hands-on at Miami Dade College’s Wolfson Campus, where he picked up the building science fundamentals that still shape how we approach every job. That means proper flashing, square frames, clean seal lines. In Miami Shores, a window that leaks air or water isn’t just an annoyance. It’s a liability. We started this company partly because Ed’s own mother got burned by a fly-by-night crew after a storm, and he figured somebody in this neighborhood ought to be doing this right. Every tech we send to your door is background-checked and uniformed, so you know exactly who’s coming before the truck pulls up. And Ed’s name is on the business. My name’s on it, so it’s going to be done right.

We also back every CWS repair and install with our Done Right Promise. If it’s not done right, we make it right. That’s a lasting standard no national chain will put in writing.

Common CWS Windows & Doors Problems We Fix in Miami Shores

Here’s what we actually see on CWS products in Miami Shores, street by street, bay side and inland:

• CWS 6900 Series Single Hung sash drops shut: The tension springs inside the balance assemblies fatigue over time, especially in rooms with daily open-close cycles. When both springs lose tension, the sash becomes a guillotine. It’s not a track problem. It’s a balance problem. We replace the balances with OEM CWS parts when available, and the window works like new.
• CWS 5900 Series Horizontal Roller seizing or flattening: The roller assemblies on the 5900 sit directly in the track, and in Miami Shores, that track collects salt residue, sand, and fine debris. Rollers flatten, bearings seize, and the panel grinds instead of glides. We’ve pulled flattened rollers out of 5900s on homes near the bay that looked more like coins than wheels. Fresh rollers, clean track, done.
• CWS 6700 Series Casement weep hole blockages: The 6700 casement has small weep holes along the bottom frame designed to drain water out. In Miami Shores, those holes clog with salt crust, pollen, and insect debris. Water backs up inside the frame, sits against the sill, and rots it from the inside. If caught early, we clear the weeps and dry the frame. If the sill is spongy, replacement is the honest call.
• CWS 800 Series Awning stripped operator gears: The crank operator on the 800 awning uses a small gear assembly that strips when the window is forced past its stop or cranked repeatedly against a misaligned sash. We replace the operator and realign the linkage so the new gears don’t eat themselves the same way.
• Failed impact glass or broken seals on CWS impact units: Miami Shores’ salt air attacks glazing seals, particularly on east-facing elevations. Once the seal fails, moisture gets between the panes and the glass clouds permanently. There’s no resealing a failed insulated unit. We measure, order the correct impact-rated lite, and replace it under warranty-safe practices.

CWS Parts & Our Repair-vs-Replace Approach

We start with OEM CWS balances, rollers, locks, and operators when they’re available. A direct-fit OEM part gets your window working correctly the first time with zero adaptation. But CWS, like every manufacturer, occasionally has lead times or discontinues a part line. When that happens, we don’t leave you hanging. We use proven Miami-grade aftermarket components with the same load ratings and dimensions. These aren’t generic hardware-store parts. They’re tested alternatives we’ve installed in Miami Shores homes for years.

The repair-vs-replace decision comes down to one question: is the frame sound? If the extrusion is solid, the glass is intact, and the issue is mechanical, we repair. A balance swap costs a fraction of a new window and extends the life of a good frame by years. If moisture has compromised the extrusion or the glass has failed, patching is throwing money at a problem that will resurface. We’ll tell you that straight. No upsell. No patching a sinking ship. Call (727) 483-7883 and we’ll give you an honest assessment.

Our CWS Service Process - Step by Step

1. 1
   Diagnosis: We inspect the specific CWS model in its installed condition. On a 6900 single hung, we pull the sash and test balance tension directly. On a 5900 roller, we lift the panel out and inspect the rollers for flat spots. We don’t guess from a photo.
2. 2
   Repair or replacement plan: We lay out options in plain English, including part availability, lead time, and honest cost. You’ll get a written line-item quote before any work starts, and our upfront pricing means the number on the quote is the number on the invoice.
3. 3
   Repair or install: For repairs, we replace the failed component with OEM or equivalent parts, clean the tracks, align the sash or panel, and lubricate hardware where appropriate. For replacements, we follow Miami-Dade HVHZ anchoring and flashing standards, including the hollow clay tile substrate work common in Miami Shores’ 1930s-1950s homes.
4. 4
   Testing: We cycle the window or door multiple times, check the seal line, verify drainage, and make sure operation takes one hand, not two. If it doesn’t feel right, we don’t call it done.
5. 5
   Warranty and follow-up: Every CWS repair and install carries our Done Right Promise. If it’s not done right, we come back and make it right.

CWS Products We Service & Install in Miami Shores

We service and install the full CWS residential lineup that’s common in Miami Shores. That includes the 6900 Series Single Hung, the 5900 Series Horizontal Roller, the 6700 Series Casement, and the 800 Series Awning. We handle insert window replacement, full single and double hung replacements, and Impact Windows upgrades, including retrofitting existing CWS frames where possible. We keep a supply of high-turnover CWS-compatible hardware in our local stock: balances for 6900s, roller assemblies for 5900s, and operator gears for 800 awnings. Less common parts we order direct with transparent lead times.

Our tech recently finished a job on a 1960s ranch near NE 96th St: a CWS 6900 single hung in the back bedroom dropped shut whenever the homeowner tried to open it. We pulled the sash, found both tension springs fatigued, and installed new OEM balances. The window now stays up with one hand. No full replacement needed.
