CWS Construction in Miami, FL | Mason Remodeling Co Miami
We provide independent CWS construction service across Miami, from Coral Gables to Brickell, with hands-on rebuilds of CWS window systems other crews won’t touch. We are not manufacturer-affiliated or authorized, which means we tell you straight when a frame is worth saving and when replacement is the smarter money. Call (850) 780-8123 for a free estimate on any CWS repair, retrofit, or full replacement.
Why Miami Residents Choose Us for CWS Service
Most General Contractors in Miami will sell you a window. Few can tell you why your CWS 800 Series frame is pitting along the bottom rail, and whether the glass is still holding its impact rating. We have been working Miami neighborhoods for well over a decade, including projects throughout Coconut Grove, and Isaac Pruett, our owner, reads a job site fast and gives homeowners a straight number with no padding.
We carry the trade knowledge that matters here: OEM-compatible parts, marine-grade retrofit fabrication, and a working understanding of Miami-Dade’s High Velocity Hurricane Zone code. You get a written price before any work starts, and every technician who arrives at your door shows a photo ID badge and wears a clean uniform. That is the Threshold Standard, and it applies to every CWS job we take.

Common CWS Construction Problems We Solve in Miami
- Salt-air pitting on CWS 800 Series frames. Coastal exposure in neighborhoods like Brickell and Edgewater accelerates aluminum corrosion. The gasket loses its seat, water intrudes, and the frame rots from the inside. We replace corroded sill sections with custom extruded 6061-T6 aluminum and install new stainless steel rollers.
- Failed laminated glass seals on 4000 Series fixed units. Hurricane-driven pressure cycling flexes the laminate until the seal breaks. You get fogging and reduced impact resistance. We source replacement glass that meets Miami-Dade NOA requirements, not just statewide Florida Product Approval.
- Worn interlock weatherstripping on 450 Series sliding doors. Wind-driven rain during Miami storm bands seeps into the track channels. We replace the weatherstripping and realign the interlock so the door seals tight against the next named storm.
- Stripped or seized operator hardware on 850 Series casement windows. Decades of salt-laden air without lubrication seize the cranks. In high-rise condos, this is a safety issue. We rebuild or replace the operator hardware and coat moving parts for the salt environment.
- Clogged weep holes from salt scale. This one hides. Our crew pulled three CWS 800 Series horizontal sliders from a 1974 condo line on Brickell Avenue where the original weep holes were clogged with salt scale; the frames had hidden aluminum rot at the sill corners. We replaced the sills with custom extruded 6061-T6 sections and installed new stainless steel rollers, keeping the original impact glass and saving the board a full re-glaze on seven units.
CWS Service in Miami: What Local Conditions Mean for Your Equipment
Miami-Dade’s High Velocity Hurricane Zone is not a suggestion. Every CWS unit in new construction or a 40-year recertification has to pass large- and small-missile tests and be on the Miami-Dade NOA-approved product list. What that means for your windows: a CWS frame that looks fine from the street can still fail recertification if the original impact rating has been compromised by corrosion or delaminated glass. We cross-check every replacement against the NOA list, not just the statewide Florida Product Approval, because the city inspector will. In Coral Gables especially, where buildings run older and the oolitic limestone bedrock complicates any structural work, recertification is the moment homeowners discover what salt air has been doing for 30 years. We handle that discovery without drama.
CWS Models & Products We Service in Miami
We service the CWS line that dominates high-rise coastal construction across South Florida. That includes the CWS 800 Series Impact Windows, the CWS 4000 Series Fixed Windows, the CWS 450 Series Sliding Glass Doors, and the CWS 850 Series Casement Windows. For CWS units under the original manufacturer timeframe, we source OEM hardware: latches, rollers, balances. That preserves the original impact rating. Past that, or for discontinued models, we fabricate marine-grade or stainless steel retrofits matched to the extrusion profile, and we are upfront when a corroded frame or delaminated glass makes replacement cheaper over a Miami recertification cycle. Our familiarity with CWS gear and the local recertification market is what sets us apart. Learn more about our CWS sales & service capabilities.

AfterCWS Service Pricing in Miami
Every CWS job here prices differently depending on the condition of the frame, the glass rating required, and the building’s recertification status. Here is what you can expect for the most common work:
| Service | Price Range |
|---|---|
| Impact Window Installation | $9,440 – $29,500 |
| Window Replacement | $5,310 – $17,700 |
| Roof Repair | $470 – $2,125 |
High-rise condo work adds rigging and access costs. Frame corrosion that has reached the sill corners adds fabrication time. A free estimate gives you a written line-item price before any work starts, so you know the number going in. Call (850) 780-8123 to schedule yours.

FAQs – CWS Construction in Miami
Yes, if the frame is structurally intact and the glass is the only failure point, we replace the panel alone. The replacement glass has to meet Miami-Dade NOA requirements, and we confirm that before ordering. Call (850) 780-8123 for an exact quote.
Often, yes. Many recertification failures come from corroded sills, seized hardware, or delaminated glass on a handful of units, not the entire window package. We assess each unit, replace what actually failed, and document the work for the building’s engineer. Call (850) 780-8123 to schedule an assessment.
The interlock weatherstripping is the weak point. Wind-driven rain during Miami storm bands forces water into the track channels, and worn weatherstripping lets it through. We check the interlock, the rollers, and the weep holes so the door holds its seal. Call (850) 780-8123 for a pre-season inspection.
No. Most aftermarket rollers are stainless steel, which is fine, but they are not matched to the CWS extrusion profile, so they wear unevenly and the door sags. We source OEM rollers where available, and for discontinued models we fabricate stainless steel rollers matched to the profile. Call (850) 780-8123 for details on your specific unit.
Yes. With our Bathroom Remodeling in Miami, we remove the old frame from the exterior and install the new one without touching interior drywall. The stucco around the opening gets cut clean and patched to match. We handle the access and the building’s work hours. Call (850) 780-8123 for a site visit and a written estimate.
