Call (561) 461-2062 to schedule your free measured survey; we bring the written price with us, not after.
Why Lantana Residents Choose Us for CGI Service
We’ve replaced CGI units on homes from Hypoluxo Island to the mainland blocks off Lake Drive, and the pattern repeats: the frame tells the truth before the sash does. Sonia Raman, who leads our crew, learned to read rough openings at Los Angeles Trade-Technical College before she ever measured a Florida stucco wall. That training shows up in how we quote - every U-factor, every impact rating, every anchor pattern written down before a contract is signed.
Our CGI sales & service covers the full current lineup, but our real specialty is the older aluminum and early vinyl units that have spent fifteen or twenty years in Lantana’s salt spray. We stock genuine CGI replacement sash, rollers, glazing beads, and hardware kits for when the frame and sill are still sound. When they’re not, we say so. Haven Clause 1 means the measured survey you keep and the written quote match; Haven Clause 4 means you get the photo record when we’re done. No verbal assurances, no change orders, no surprises.
Our technicians are background-checked, uniformed, and identified by license number before arrival. The 365-Day Done Right Promise is stamped on every job, not offered as a courtesy. And calls are answered by a live person, 24/7.
Common CGI Windows & Doors Problems We Solve in Lantana

- Corroded aluminum sills and weep ports. CGI’s early-generation aluminum frames installed in Lantana during the 1990s and 2000s have corroded at the sill from year-round Intracoastal salt spray. Water intrudes behind the stucco, and by the time you see interior bubbling the frame is already compromised. We see this on east-facing elevations from Ocean Avenue to the beachfront corridor.
- Vinyl sash warping on Atlantic and west walls. CGI vinyl sashes on Lantana’s east- and west-facing walls warp faster than the same units even a few miles inland. The UV here is intense, the humidity is salt-laden, and the combination breaks weather seals that would hold elsewhere. Once the seal goes, the impact rating is void.
- Seized rollers and frozen tracks. CGI HurricaneShield sliders and horizontal rollers oxidize and seize when the hardware isn’t marine-grade. We routinely find rollers frozen solid to the track, the sash immovable without prying. On a 1962 CBS home off Lake Drive, we cut out a slider whose rollers had corroded to the track from years of salt spray.
- Dried gaskets pulling from the frame. Older CGI units lose gaskets and weatherstripping to the combination of heat and salt air. Wind-driven rain migrates past the frame on Atlantic-facing elevations, and the homeowner notices it first as a musty smell, not a visible leak.
- Jalousie-to-impact conversions that county code mandates as full tear-outs. Palm Beach County inspectors will not approve jalousie windows on any permitted project. Lantana’s older residential blocks still contain original louvered jalousie units. What looks like a simple sash replacement in another town is legally a full-frame tear-out here. We quote both repair and replacement when the frame is sound, but on these homes it rarely is.

AfterCGI Service in Lantana: What Local Conditions Mean for Your Equipment
Lantana sits directly on the Intracoastal Waterway with the Atlantic less than a mile east, creating one of the most concentrated salt-air corrosion environments in Palm Beach County. Its dense stock of 1950s-1970s CBS homes - many still fitted with original jalousie or single-pane aluminum windows - are simultaneously non-compliant with Palm Beach County’s impact-resistant glazing requirements and actively corroding. This means full replacement, not repair, is the near-universal outcome of every windows-and-doors call in town.
For CGI owners specifically, this geography translates to accelerated hardware failure. Standard aluminum frames and door thresholds oxidize and seize noticeably faster here than even a few miles inland in communities like suburban Boynton Beach. Marine-grade hardware isn’t an upgrade in Lantana; it’s a necessity. The modest working-class character of the town relative to neighboring communities means deferred maintenance is common, and by the time we get the call, the corrosion has usually progressed past the point where a parts swap is honest. We stock genuine CGI replacement components, but we’ll tell you when a repair would only buy a season or two. Measure it right the first time. Everything after that is just paperwork.
CGI Models & Products We Service in Lantana

We work on the full CGI sales & service lineup, with emphasis on the units we see most in Lantana’s coastal CBS housing stock:
- CGI Sentry Series - vinyl impact windows, our most common full-frame replacement for Lantana homes upgrading from jalousie or corroded aluminum
- CGI Estate Series - vinyl replacement windows for frame-in-sound applications where the sill and anchoring are still intact
- CGI HurricaneShield - impact-rated sliding glass doors, specified with marine-grade rollers for Intracoastal exposure
- CGI aluminum single-hung and horizontal roller systems - legacy units we repair where possible, replace where the sill has corroded
We stock genuine CGI replacement sash, rollers, glazing beads, and hardware kits locally for fast turnaround on Lantana service area calls. When the frame is sound, we repair. When it’s not, we quote full-frame replacement with the same written price before work starts.

FAQs - CGI Windows & Doors in Lantana
Sometimes, but less often than homeowners hope. If the sill and frame are structurally sound and the corrosion is surface-level, we stock genuine CGI replacement sash, rollers, and hardware kits for a targeted repair. On most Lantana homes we see, especially the 1950s-1970s CBS stock near the Intracoastal, the aluminum frame has corroded at the weep ports or sill from salt spray, and a repair would last a season or two at most. We quote both options and tell you which is which. Call (561) 461-2062 for an exact assessment - estimates are free.
Yes, but only as a full-frame replacement. Palm Beach County inspectors will not approve jalousie windows on any permitted project. The louvered glass slats have no weather seal and zero wind-load resistance. We remove the entire jalousie frame, flash the rough opening, and install CGI Sentry Series impact-rated vinyl units that pass inspection on the first pass. The permit paperwork shows the jalousie units were eliminated, not covered over. Call (561) 461-2062 to schedule a measured survey - estimates are free.
Salt-laden humidity from the Intracoastal and Atlantic accelerates oxidation of standard aluminum hardware by a factor we can see with our own eyes. Rollers, tracks, and thresholds that would last a decade inland seize in four to six years here. We specify marine-grade hardware on every CGI slider and horizontal roller we install in Lantana, and we tell owners when their existing hardware is standard-grade and living on borrowed time.
We install both, but we specify vinyl impact for most Lantana full-frame replacements. CGI’s Sentry Series vinyl handles the salt-air environment better than aluminum over the long term, and the thermal performance is superior for west- and east-facing walls. We use CGI aluminum single-hung and horizontal roller systems where the homeowner specifically requests aluminum or where the existing frame is sound and only the sash needs replacement. The choice is documented in the written scope before work starts.
A typical 8-12 opening Lantana CBS home takes two to three days for full removal, rough-opening prep, and installation, plus a half-day for final trim and cleanup. Jalousie tear-outs add time because the rough openings require re-flashing. Permits are pulled before work starts, and inspections are scheduled so there’s no gap between install and sign-off. We don’t quote speed; we quote done right. Call (561) 461-2062 for a timeline specific to your openings - estimates are free.
Service Areas Near Lantana

We run CGI service in Lake Worth north of us, where the housing stock shifts to more 1920s-1940s frame construction with different anchoring challenges. South toward the Boynton Beach corridor, we handle CGI service in Boynton Beach on newer CBS and some mixed-era developments where the salt exposure is slightly less concentrated than Lantana’s Intracoastal edge. We also work Palm Springs, Greenacres, and Palm Beach proper on request, though our daily routes center on the coastal Palm Beach County strip where salt air and impact code converge.
