CWS Construction in Miami, CA | Rowan Construction Group
We provide independent Cws service in Hialeah and across Miami, handling everything from impact window replacements to full kitchen remodels and roof repair. The one thing that makes our CWS work here different: every install or repair we touch must clear Miami-Dade’s Notice of Acceptance (NOA) product and anchor-inspection rules, and every member of our crew has worked under that inspection regime for years. If your CWS unit needs service, call (470) 298-9650 for a written estimate before any work starts.
Why Miami Residents Choose Us for CWS Service
Rowan Construction Group has been installing and servicing CWS products in Miami-Dade for over a decade. Our crew has handled hundreds of CWS-adjacent construction projects, including custom masonry openings, structural revisions, and post-hurricane reinstalls. Grant Rowan, our owner, trained in construction technology at Los Angeles Trade-Technical College and has spent the better part of two decades working on residential and light commercial projects; that background means we approach every CWS job the way an inspector would, looking at anchors, substrate, and load paths before we touch a finish.
We are an independent CWS service provider, not manufacturer-affiliated or authorized. That independence lets us be honest about repair-versus-replace decisions. We use genuine CWS parts when available for warranty-critical components like impact glass and framing. Otherwise, we source Miami-Dade NOA-compliant aftermarket gaskets, rollers, and fasteners. We are licensed and insured, and every visit includes a documented photo record as a standard deliverable.
Common CWS Construction Problems We Solve in Miami

- Impact glazing delamination from salt air and humidity. The constant 80%+ humidity and salt spray along the Atlantic coast works its way between glass and laminate layers over time. You’ll see fogging first, then a milky haze that will not wipe off. Once delamination starts, the impact rating is compromised and most units need glass replacement, not a reseal.
- Frame warping on south-facing units. Miami’s intense UV exposure and daily thermal cycling put real stress on aluminum frames. South-facing CWS windows absorb heat all afternoon, expand, contract, and eventually warp enough to break the seal. You will notice drafts or water staining at the bottom corners of the frame.
- Corrosion on interlock weatherstripping and roller assemblies. Salt spray inland of Biscayne Bay and the ocean accelerates corrosion on metal components other cities never think about. CWS sliding doors near the water stiffen up because the interlock weatherstripping corrodes and the rollers bind. Lubrication buys weeks; replacement buys years.
- Post-hurricane debris strikes on non-HVHZ-compliant installs. We see this after every storm season. A window that was not installed to Miami-Dade HVHZ standards cracks or dislodges when a coconut or roof tile hits it. If the unit lacks the right NOA and anchor system, the whole opening often needs to come out and get redone properly.
- Water intrusion at the sub-sill pan. Miami’s driving rain, especially during summer squalls, finds every short-cut installation. If the sub-sill pan (the waterproof tray under the window) was cut too short or left unsealed, water wicks into the masonry opening and shows up as drywall staining below the unit.

AfterCWS Service in Miami: What Local Conditions Mean for Your Equipment
Here is the local fact that shapes everything about CWS service in Miami: Miami-Dade County requires every CWS window or door installed to have a valid NOA number specific to the product and anchor system. Inspectors verify that the exact anchor bolts match the NOA drawings. Use a different size or spacing and the entire opening must be redone. That rule does not apply in Broward or Palm Beach the same way, and it catches contractors who relocate from other states off-guard on their first job. For a CWS owner, it means you cannot just swap in any off-the-shelf window or anchor a frame with whatever fastener is in the truck. Framing repairs, re-anchoring, even a window swap all have to reference the NOA paperwork. We keep that documentation in every job file. For example, in a 1970s CBS home in Little Havana, where the walls are concrete block rather than wood frame, the correct anchor pattern is not theoretical. The inspector will check it against the drawing before signing off. We have seen entire openings torn out because someone used the wrong anchor diameter. We spec the NOA first and the aesthetic second.
CWS Models & Products We Service in Miami

We service CWS 3000 Series windows, and our Driveway & Pavers in Miami team knows Miami sees plenty of them in Brickell condos and older CBS homes alike. The 3000 Series is impact-rated, which matters anywhere in the HVHZ. CWS 4000 Series sliding glass doors are common in mid-century homes and beachfront properties, and CWS 5100 Series casement windows show up on higher-end remodels. We also work on CWS architectural curtain wall systems, mostly on commercial and mixed-use buildings in Edgewater and downtown. Parts coverage follows our independence: genuine CWS parts for warranty-critical components like impact glass and framing assemblies, and NOA-compliant aftermarket gaskets, rollers, and fasteners when those deliver honest value. Most common rollers and gaskets are stocked locally for fast Miami turnaround.

FAQs - CWS Construction in Miami
Yes, if the glass is part of the impact-rated assembly. Miami-Dade inspectors treat any replacement of impact glazing as a repair that must reference the product’s NOA for the replacement glass and the anchoring system. Replacing a single pane of CWS 3000 Series glass without NOA documentation will fail inspection. Call (470) 298-9650 and we will pull the NOA before we quote.
We can. Stiff operation on CWS sliding doors near the beach usually comes from salt-spray corrosion on the roller assemblies and interlock weatherstripping. We replace the corroded components with NOA-compliant aftermarket parts, clean the track, and re-align the door. If the frame itself is corroded through, we will tell you honestly whether replacement costs less than rebuilding the sash. Call (470) 298-9650 for a written estimate.
Condensation between the panes means the impact or insulated glass unit has lost its seal. On most CWS units that is a glass replacement, not a frame repair. If delamination from salt air has also started, replacement is almost always the right call. We will open the unit, document what we find, and write the quote before ordering glass. Call (470) 298-9650.
We will inspect it first. A slightly dented frame can sometimes be re-anchored and resealed, but if the dent affected the glass seat or the anchor slots, the frame needs replacement. Miami-Dade inspectors will not pass an opening where the frame is compromised, and neither will we. We will show you the photo record and a written quote either way. Call (470) 298-9650.
In most cases, yes. Miami-Dade treats impact window and door work as structural, which means a permit and inspection by the building department. Small repairs like roller or weatherstripping replacement are typically exempt. We pull permits on every job that requires one, and we will tell you upfront whether your project does. Call (470) 298-9650 for a free estimate.
