Why Lantana Residents Choose Us for CWS Service
We have replaced CWS windows and doors in Lantana long enough to know which extrusion profiles from the 2000s and 2010s are still serviceable and which have reached end-of-life from salt-air corrosion. Our crew carries CWS OEM glass packages, rollers, and weatherseal for the Series 5000 and 7000 lines, plus aftermarket hardware for the early CWS profiles that the factory no longer stocks.
Sonia Raman, our owner, grew up in Miami and learned glazing and frame installation through the building trades program at Miami Dade College before spending two decades on actual job sites. She keeps a running list of every window she has had to pull and replace because a previous installer used the wrong sealant - it is longer than she would like, and it is the reason she checks her own crew’s caulk joints before any truck leaves a site. In Lantana, that discipline matters more than most places. The southeast sea breeze off Lake Worth Lagoon pushes salt-laden air across properties east of North Dixie Highway and South Dixie Highway, and we have seen CWS aluminum frames corrode through in half the time they last in Greenacres or west Boynton Beach.
Our CWS sales & service work is governed by the Haven Standard: written price before any tool is lifted, background-checked uniformed technicians with license numbers, documented photo record on every visit, and the 365-Day Done Right Promise stamped on every job. We have completed more than 18,000 openings since 2012 under that standard.
Common CWS Windows & Doors Problems We Solve in Lantana

- Salt-air oxidation on CWS aluminum frames east of Dixie Highway. The white powdery corrosion around weep holes and sill screws looks like dirt until the frame pits and the sash stops sealing. We see this most often on CWS Series 7000 single hungs in 33460 homes between Federal Highway and the Intracoastal, where the lagoon breeze is constant.
- Failed glazing tape and sealant after 10-15 years of UV and lagoon humidity. Water tracks behind the frame and rots CBS block or bubbles stucco. On one job near Lucerne Avenue, the homeowner thought they had a roof leak; the water was entering through degraded CWS glazing tape and running down the interior block.
- Roller and track failure on CWS horizontal rollers in out-of-square openings. Many 1950s-60s CBS rough openings were never built to modern tolerances. The sash binds, the rollers flat-spot, and the homeowner ends up forcing the window closed. We measure diagonals before ordering any CWS Series 5000 replacement.
- Jalousie-era retrofit failures. Older CWS replacements were sometimes shoehorned into unmodified jalousie framed openings where header and sill heights do not match current CWS frame depths. Air and water infiltrate at the perimeter. These are the jobs Sonia’s sealant list was made for.
- Corroded lock sets and hardware on CWS impact entry doors. The salt air attacks door hardware faster than window hardware because doors get opened more often and the moving parts see more abrasion. We stock CWS OEM lock sets and turn to quality aftermarket only when the profile is discontinued.

AfterCWS Service in Lantana: What Local Conditions Mean for Your Equipment
Lantana’s building department processes a disproportionate share of jalousie-to-impact-slider permit conversions, and there is a reason that shows up in our CWS work every month. The 1950s louvered-glass windows common in 33460 bungalows near the Intracoastal Waterway cannot be brought into code compliance with film or shutters - the full louvered frame has to come out, and the CBS rough opening often has to be modified to accept a CWS Series 5000 impact horizontal roller or a CWS impact entry door system. This is not a sales pitch. It is a Palm Beach County wind-load requirement that virtually every pre-1992 home in that corridor eventually must address, and the conversion requires a contractor who understands both CWS frame depths and the structural realities of 60-year-old CBS construction.
We took a call on a 1961 CBS ranch off West Lantana Road near the Intracoastal where the original jalousie windows in the living room still had their 1950s louvered glass and the entry door was a hollow-core wood slab swollen from lagoon humidity. Our crew pulled the jalousie frame, squared and shimmed the CBS rough opening, and set a CWS Series 5000 impact horizontal roller with a new sill pan and a CWS impact fiberglass entry door. The homeowner passed Lantana’s wind-load inspection on the first walkthrough and the salt-driven corrosion issue at the old aluminum sill was gone. “Measure it right the first time and the install is already half done.” That is how we work.
CWS Models & Products We Service in Lantana

We work on the full CWS residential line: Series 7000 Impact Single Hung, Series 5000 Impact Horizontal Roller and 3-lite sliders, CWS Impact Entry Door Systems in fiberglass and aluminum, and the CWS Vinyl Impact Window Series in multi-lite configurations. Our truck stocks CWS OEM replacement glass, rollers, lock sets, and weatherseal for current production profiles. For discontinued CWS lines - the early 2000s aluminum single hungs and jalousie-era retrofits - we source quality aftermarket hardware that meets or exceeds original spec.
When salt corrosion has reached the frame or the rough opening is non-compliant for tear-out, we tell homeowners honestly that a full-frame CWS impact replacement is cheaper over ten years than chasing seals on a failing frame. We do not sell parts for parts’ sake. Our Lantana service area coverage means we can usually inspect within a day or two and schedule repair or replacement from there.

FAQs - CWS Windows & Doors in Lantana
Yes. The 1950s louvered-glass windows in 33460 homes near the Intracoastal cannot be made code-compliant with film or shutters, so the full frame must come out. We modify the CBS rough opening as needed and install CWS Series 5000 impact horizontal rollers or CWS Series 7000 single hungs that pass Palm Beach County wind-load inspection. Call (561) 421-3844 to schedule a measured survey - estimates are free.
Yes. Lantana sits directly on Lake Worth Lagoon, and the prevailing southeast sea breeze pushes salt-laden air across nearly every property east of Dixie Highway. We see CWS aluminum frames corrode in roughly half the time they last a few miles inland. Our recommendation for homes in that band is CWS vinyl impact or fiberglass entry door systems, or rigorous annual maintenance on aluminum if replacement is not yet scheduled.
It depends on the existing frame condition and the rough opening. If your current frame is a CWS unit installed after 2005 with intact sill pan and minimal corrosion, an insert may work. If you are in a 1950s-60s CBS home with original jalousie openings or salt-damaged aluminum, full-frame replacement with rough-opening modification is usually necessary for code compliance and long-term performance. We measure before we recommend.
We stock CWS OEM replacement glass, rollers, lock sets, and weatherseal for current Series 5000 and 7000 profiles. For discontinued CWS lines - early 2000s aluminum single hungs and jalousie-era retrofits - we use quality aftermarket hardware that meets or exceeds original spec. We do not promise OEM parts we cannot source.
A standard CWS full-frame replacement on a 1,200-square-foot CBS ranch takes two to three days, including permit-related inspection scheduling. Jalousie-to-impact conversions with rough-opening modification add a day. We pull permits, pass inspections, and leave a documented photo record. Call (561) 421-3844 for a timeline specific to your home - estimates are free.
