CWS Windows & Doors in Lake Worth, FL | Sightline Windows & Doors Lantana
We provide independent CWS service across Lake Worth - not authorized by the manufacturer, but experienced with every CWS profile still sitting in the city’s mid-century CBS homes. The one thing that makes our CWS work here different is that we understand how Lake Worth’s salt-air lagoon microclimate and historic overlay requirements change what “service” actually means for these units.

Why Lake Worth Residents Choose Us for CWS Service
We’ve been measuring, sourcing, and installing CWS windows and doors across Palm Beach County since 2012. That includes the CWS 500 Series single-hungs, the 1300 Series horizontal rollers, and the aluminum jalousie units that came original to many Lake Worth homes built between the 1950s and 1970s. Sonia Raman, our owner, picked up her first glazing tools at Los Angeles Trade-Technical College before logging two decades of fieldwork in South Florida. She writes down the exact U-factor and impact rating of every unit before a contract is signed - numbers on the page, not promises in the air.
Our CWS sales & service approach is built on the Haven Standard: a measured survey you keep, a written price that cannot change, and a documented photo record when the job is done. We stock genuine CWS replacement hardware locally for fast turnaround, and when a frame is pitted through or a unit is non-impact in a wind-borne debris zone, we tell you the honest answer is replacement. No urgency theatre, no verbal assurances - just the specification, the price, and the work.
Common CWS Windows & Doors Problems We Solve in Lake Worth

- Salt-air pitting on CWS aluminum frames. Lake Worth’s position along the Lake Worth Lagoon creates a persistent salt-air microclimate that corrodes aluminum years faster than properties even a mile west. We see oxide bloom and seized hardware on lagoon-facing elevations that inland Palm Beach County simply doesn’t produce.
- Glazing seal failure on older CWS non-impact units. The original single-pane and jalousie windows in Lake Worth’s 1950s-1970s CBS stock weren’t built for wind-driven rain at coastal pressures. Once the gasket degrades, water passes the seal and fogs the glass - a failure mode that accelerates where salt air breaks down the rubber.
- Corroded or frozen jalousie crank and louver hardware. Original CWS jalousie windows in Lake Worth’s concrete block openings often carry cranks that haven’t turned in decades. The mechanism seizes, the louvers won’t close, and the unit becomes non-operable and non-sealable - a security and storm-preparedness issue, not just a convenience problem.
- Leaking CWS sliders and flat-spotted rollers. The original aluminum track on CWS Sentinel sliding glass doors and 1300 Series horizontal rollers wears into flat spots, or the sill corrodes into the concrete block rough opening itself. We find this where drainage has been blocked by salt-caked debris.
- Non-impact CWS units in a wind-borne debris zone. Palm Beach County requires impact-rated glazing or approved storm protection on all replacement openings. Many Lake Worth homes still carry original non-impact CWS units that cannot legally be replaced with like-for-like. We specify the right impact-rated successor and pull the permit.

AfterCWS Service in Lake Worth: What Local Conditions Mean for Your Equipment
Lake Worth’s Historic Preservation Board holds jurisdiction over window and door replacements in the downtown historic overlay district. Touching a CWS opening in that zone can require approval for profiles, muntin patterns, and materials before a permit is pulled - a bureaucratic step that doesn’t exist in neighboring Lantana or unincorporated Palm Beach County. We’ve navigated this process for CWS replacements near Lucerne Avenue and the surrounding historic core, where a standard Impact Windows & Doors - Lake Worth job can add weeks if the contractor doesn’t submit the right documentation upfront. The board wants to see that replacement units match the original sightline and division pattern, which means CWS custom options or approved alternatives with simulated divided lites - not every contractor’s stock size. For Lake Worth homeowners in the overlay, this isn’t optional, and it changes both the timeline and the specification. We build this step into our measured survey and written scope so the price accounts for the full process, not just the installation day.
CWS Models & Products We Service in Lake Worth

We work on the CWS product lines found in Lake Worth’s existing housing stock: the CWS 500 Series impact single-hung, the CWS 1300 Series horizontal roller, the CWS Sentinel impact sliding glass door, and the CWS aluminum jalousie / louvered window still original to many 1950s-1970s CBS homes. Our parts inventory includes genuine CWS jalousie cranks, rollers, glazing gaskets, and matching frame profiles. Where CWS OEM parts are no longer produced, we use quality aftermarket components that meet the original specification. For impact-Resistant Windows, full frame replacement, and hurricane-proof front & entry doors, we specify from our eight manufacturer lines - CWS among them - by what the opening requires, not by what is in stock. We keep common CWS hardware on hand for Lake Worth service area calls to minimize return trips.

FAQs - CWS Windows & Doors in Lake Worth
Yes, if your property sits within the downtown historic overlay district. The board reviews profiles, muntin patterns, and materials before permit issuance. We include this step in our measured survey and written scope so the price covers the full process. Call (561) 461-2062 to confirm whether your address falls under board jurisdiction.
Lake Worth’s lakefront position along the Lake Worth Lagoon creates a salt-air microclimate that pits aluminum frames, corrodes hardware, and degrades glazing seals measurably faster than properties inland. The difference of a single mile can mean years of additional service life. Call (561) 461-2062 and we’ll assess whether repair or replacement is the honest answer for your specific elevation.
Sometimes. If the frame isn’t pitted through and the concrete block rough opening is sound, we can replace cranks, louvers, and gaskets with genuine or quality aftermarket parts. When the frame is compromised or the unit is non-impact in a wind-borne debris zone, we recommend impact-rated replacement. We stock CWS-compatible jalousie hardware for fast Lake Worth turnaround.
Fogging indicates seal failure on insulated glass units. For CWS 500 Series impact single-hungs, we can often replace just the sash or IGU rather than the full frame, provided the frame is structurally sound and meets current impact requirements. We measure the sightline and specify the exact replacement before quoting.
Yes. Lake Worth’s predominant 1950s-1970s CBS construction requires careful measurement of the concrete block rough opening, proper anchoring into masonry, and new flashing and sill pans to prevent water intrusion. We document the opening with photos, pull the permit, and leave you the photo record on completion. Call (561) 461-2062 to schedule your measured survey.
