CWS Construction in Miami, FL | Rowan Construction Group Miami
We provide independent CWS service across Miami - not manufacturer-authorized, but field-tested through over a decade of installs and repairs in High-Velocity Hurricane Zone conditions. The one thing that makes our CWS work here different: we navigate Miami-Dade’s Notice of Acceptance (NOA) product-approval system as standard practice, because inspectors in this county will fail a rough inspection for missing or expired NOA paperwork even when the same window passes in Orlando or Tampa. Call (786) 321-4970 to schedule your free estimate.
Why Miami Residents Choose Us for CWS Service
Grant Rowan learned the trade at Los Angeles Trade-Technical College, spent two years in the building construction program, then ran crews through gut renovations in Coconut Grove and commercial builds across Miami-Dade. That background shows up in how we handle CWS products here: we know which Series 7000 glazing assemblies hold up to repeated hurricane-season pressure cycles, and which CWS sales & service approaches actually work in salt-air environments.
We’ve been in South Florida long enough to see what happens when out-of-state contractors install CWS impact windows without checking the Miami-Dade product-control database. The NOA expires, the inspection fails, and the homeowner is left with open walls during rainy season. We pull current documentation before we order material, every time.
Our crews are background-checked and uniformed; a live person answers calls 24/7. Every visit includes a documented photo record - not an upgrade, just how we work. Under Clause 1 of the Haven Standard, you get a written price before anyone picks up a tool. No exceptions. That’s kept our projects within a few percent of the agreed number across 4,000-plus jobs since 2007.

Common CWS Construction Problems We Solve in Miami
- Corroded stainless-steel fasteners in CWS impact window frames - Salt-air exposure near Biscayne Bay accelerates pitting on hardware that looks fine inland. We find this regularly in Coconut Grove and Key Biscayne installs where the original contractor used standard-grade anchors. The pitting eventually breaks the seal, and the window loses its impact rating without visible glass damage.
- Water infiltration behind CWS stucco-integrated flanges on CBS walls - Miami’s housing stock is dominated by concrete block and stucco, especially in pre-1992 neighborhoods like Little Havana and Allapattah. Original flashing details on these homes were never upgraded to HVHZ standards. Water gets behind the flange, rots the substrate, and shows up as interior staining months later.
- Structural silicone seal failure in CWS Series 7000 glazing - Repeated pressure cycles during hurricane season degrade the bond between glass and frame. The window fogs, and more critically, it no longer meets impact-resistance specs. Insurance adjusters flag this during post-storm claims.
- CWS door threshold and track failure in Miami Beach Art Deco buildings - Wind-driven rain and salt spray eat at hardware in 1930s-40s structures where historic-preservation review limits replacement options. We’ve replaced CWS Coastal Series tracks in MiMo buildings where the original specification didn’t account for ground-level salt exposure.
- Expired or missing NOA documentation blocking permit approval - This is the paperwork trap that delays out-of-state contractors. Miami-Dade inspectors fail rough inspections for expired NOA numbers even when the product carries Florida Product Approval elsewhere. We verify current NOA status before ordering material.
CWS Service in Miami: What Local Conditions Mean for Your Equipment
Miami sits in the High-Velocity Hurricane Zone, a designation shared only with Broward County and nowhere else in Florida. Every CWS impact window and door installed here must carry a valid Miami-Dade County Notice of Acceptance number on the permit submittal - a product-approval layer that does not exist in Orlando, Tampa, or any other major Florida market. Inspectors will fail a rough inspection for a missing or expired NOA even if the product is rated in every other county. This is not a paperwork preference; it is a legal requirement that shapes every CWS project we take on in Miami service area neighborhoods from West Flagler to Miami Shores.
The consequence for CWS owners is real. That NOA number ties the specific product to HVHZ-tested performance criteria: missile-impact resistance, cyclic pressure loading, and anchorage pull-out values calibrated to Miami-Dade’s wind-speed maps. A CWS Series 7000 window with Florida Product Approval but no current Miami-Dade NOA cannot legally be installed here. We check the product-control database before we quote, because discovering the gap at inspection costs weeks and opens the building to weather.
CWS Models & Products We Service in Miami
We work with the full CWS residential line as installed in Miami’s market: Series 7000 Impact-Resistant Windows, StormGuard Entry Doors, Coastal Series Sliding Glass Doors, and ThermaPro Hurricane Panels. Our stock includes OEM gaskets, rollers, and impact glazing for current production runs. For discontinued CWS lines, we source high-quality aftermarket components - stainless-steel hardware, NOA-approved seals - that meet or exceed HVHZ requirements.
We keep common CWS failure parts on hand for CWS sales & service calls: silicone glazing tape, stainless anchor bolts rated for salt-air exposure, and replacement thresholds for Coastal Series doors. This cuts turnaround time on repairs in Miami Beach, Coral Gables, and other coastal zones where corrosion moves fast.

AfterCWS Service Pricing in Miami
These are the ranges we see on CWS-related work in Miami’s current market. Every quote is a flat written price with a written scope - no call-for-pricing, no open-ended allowances.
| Service | Price Range |
|---|---|
| Impact Window Installation | $9,440 - $29,500 |
| Window Replacement | $5,310 - $17,700 |
| Roof Repair | $470 - $2,125 |
What moves the number: frame condition, whether the existing opening needs re-flashing to HVHZ standards, and whether the CWS product specified has a current NOA in the Miami-Dade database. Pre-Andrew homes in Little Havana or Allapattah often need additional anchorage work that post-1992 construction does not. We note this in the written scope before you sign.

FAQs - CWS Construction in Miami
Yes. Miami-Dade County requires a valid NOA number specific to this county on every permit submittal, and inspectors will fail your rough inspection without it. Florida Product Approval alone is not sufficient here. Call (786) 321-4970 and we’ll verify your CWS product’s current NOA status at no charge.
We evaluate frame integrity and anchor condition. If corrosion is limited to fasteners and the frame substrate is sound, we replace with stainless-steel hardware and reseal. If the frame or anchorage is structurally compromised - common in pre-Andrew homes near the coast - we recommend full replacement to current HVHZ standards. Call (786) 321-4970 for a free assessment.
Usually installation or maintenance. Wind-driven rain overwhelms thresholds where the track seal has degraded or the weep holes are blocked by salt buildup. In Miami Beach’s Art Deco and MiMo stock, historic-preservation constraints sometimes limit replacement options, but we can often restore function with OEM or equivalent track assemblies and proper flashing. Call (786) 321-4970 to schedule inspection.
June through November imposes hard sequencing constraints. We avoid open-structure phases during named storm watches, and permit timelines swell ahead of season as homeowners rush to complete envelope work. We plan CWS installs in spring and early fall where possible, with buffer built into schedules for weather holds. Call (786) 321-4970 to discuss timing for your project.
OEM when available and cost-effective - gaskets, rollers, impact glazing. For discontinued CWS lines, we use high-quality aftermarket components that meet or exceed HVHZ requirements, including stainless-steel hardware and NOA-approved seals. We document what we install and why in your photo record. Call (786) 321-4970 for specifics on your model.
