Why Lantana Residents Choose Us for CWS Service
We’ve worked on CWS units in Lantana since 2012, long enough to know which Series 600 single hungs were installed during the 2004-2006 post-hurricane rush and which are original to 1990s builds. That history matters because the failure pattern changes with the decade. Sonia Raman, who leads our crew, learned to read a rough opening at Los Angeles Trade-Technical College before she ever drove a South Florida freeway, and she’s spent the better part of two decades measuring and installing across Palm Beach County. Her crew logs regular work along Lantana’s beachfront corridor where salt air and hard summer storms test every frame.
We stock CWS-compatible rollers, locks, and marine-grade thresholds locally for faster turnaround, but we’re direct about what that inventory can and cannot fix. Our CWS sales & service covers the full product line, and our independence from the manufacturer means we carry no obligation to push replacement when repair is genuinely viable. The Haven Standard governs every opening: written price before work starts, verified crew with license number on arrival, documented photo record when finished, and the 365-Day Done Right Promise stamped on the paperwork.
Measure it right the first time. Everything after that is just paperwork.
Common CWS Windows & Doors Problems We Solve in Lantana

- Seized rollers and corroded locks on Series 600 and 8000 units. Lantana’s direct Intracoastal exposure accelerates aluminum oxidation far beyond inland rates. We’ve replaced CWS rollers on Ocean Avenue homes that failed within four years of installation. The salt crystals work into the bearing races and freeze them solid.
- Impact seal degradation and water intrusion. CWS impact window gaskets face dual assault here: UV intensity reflected off the water plus salt spray carried on easterly winds. The glass stays intact but the frame perimeter leaks. We see this most often on east-facing installations in the older CBS blocks near the water.
- Sliding door track failure from packed sand and salt. Lantana’s beach proximity means wind-blown sand infiltrates CWS sliding door tracks, grinding against rollers until the panel jumps track or the aluminum track itself spalls. A homeowner on Lakeside Drive in Lantana called us about exactly this: a leaking CWS sliding glass door in their 1965 CBS home with the track packed with corroded aluminum oxide and the original impact rating long expired. We performed a full-frame tear-out, replaced the unit with a CWS Series 8000 impact horizontal roller, and upgraded the threshold to marine-grade stainless. The new door passed Palm Beach County inspection on the first visit.
- Sagging entry door thresholds and corroded hinges. Original CWS entry door systems in Lantana’s 1950s-1970s homes lose their impact rating when thresholds oxidize and hinges weaken. Water reaches the interior sill, and the door no longer seats properly against the weatherstrip.
- Jalousie window obsolescence. These louvered units are still scattered through Lantana’s older residential blocks. They cannot be repaired into code compliance - Palm Beach County inspectors will not approve them on any permitted project. Full-frame tear-out is the only path.

AfterCWS Service in Lantana: What Local Conditions Mean for Your Equipment
Lantana’s roughly two-square-mile footprint includes some of the oldest continuously occupied CBS homes on the Intracoastal, and the town’s building department requires a full permit and inspection for any window or door replacement - no minor repair exceptions - because of the wind-borne debris region designation. This means even a single failed CWS window in a 1960s home triggers a full-frame code-compliant replacement with Impact Windows & Doors - Lantana, not a sash swap. The permit process adds roughly $150-$400 to project cost depending on opening count, and the inspection requires documented impact ratings, installation method, and fastening schedule. We’ve walked this paperwork through Lantana’s building department enough times to know which details stall approval and which sail through. For CWS owners, this regulatory reality reshapes the repair-versus-replace calculation: a roller replacement on a Series 600 single hung might cost $220 in parts and labor, but if the frame is original to a 1965 build, the permit requirement makes full replacement with a current CWS impact-rated unit the only compliant path. We flag this during our measured survey so the written quote reflects actual project scope, not a partial fix that fails inspection.
CWS Models & Products We Service in Lantana

We work on the full CWS residential line: Series 600 Impact Single Hung, Series 8000 Impact Horizontal Roller, Impact Entry Door System, and Vinyl Impact Casement. Our Lantana service area coverage means we keep common CWS hardware in stock - rollers, locks, tilt latches, and marine-grade thresholds - for same-week turnaround on service calls. For discontinued series, we source aftermarket parts that meet Florida impact and marine-grade standards, and we document the specification on your written quote. We do not represent CWS or carry factory authorization; our assessments are based on field measurement and code requirement, not brand incentive.

FAQs - CWS Windows & Doors in Lantana
Yes. Lantana’s building department requires a full permit and inspection for every window and door replacement because Palm Beach County designates the town as a wind-borne debris region. There are no repair exceptions. We pull the permit, schedule the inspection, and include both costs as line items on your written quote. Call (561) 461-2062 to schedule your free measured survey.
No. Jalousie windows cannot be brought into code compliance regardless of repair scope. Palm Beach County inspectors will not approve them on any permitted project. Full-frame replacement with an impact-rated CWS unit is the only path. We’ve replaced jalousies on homes throughout Lantana’s older residential blocks; the permit and inspection process is standard and we handle it start to finish.
The Intracoastal proximity creates a concentrated corrosion environment. CWS aluminum rollers and locks that last 15-20 years in Greenacres or suburban Boynton Beach often fail in 4-7 years in Lantana’s beachfront corridor. We specify marine-grade stainless hardware on all replacements and document the specification on your quote.
Glass-only replacement is possible if the frame is intact, the impact rating is current, and the failure is limited to seal breach or glass fracture. In practice, Lantana’s salt-air corrosion usually compromises the frame hardware and threshold simultaneously, making full-unit replacement the more durable fix. We assess this during our measured survey and quote both paths when both are viable.
The CWS Series 600 Impact Single Hung for standard openings and the Series 8000 Impact Horizontal Roller for larger walls or patio conversions are common choices for our Window Replacement in Lantana. Both carry the impact ratings and marine-grade hardware specifications that satisfy Palm Beach County inspection requirements. For entry doors, we specify the CWS Impact Entry Door System with stainless threshold and hinge set. Call (561) 461-2062 and we’ll measure your rough openings and quote exact units with U-factor and SHGC documented.
