This page is for Lantana homeowners who already own CGI products or are comparing CGI against other impact-rated lines for a replacement. You will find series-specific failure modes, real price ranges, and what our crew does differently on a CGI job versus a generic install.
How CGI Products Fail - and How We Fix Them
- Sentinel by CGI single hung sashes drop or tilt unevenly. The balance shoe in the jamb liner cracks after repeated cycling in Lantana’s salt air, especially on east-facing elevations within a half-mile of the beachfront corridor. We replace with OEM balance assemblies rather than aftermarket shoes, which saves the sash but requires us to pull the jamb liner to verify the shoe track isn’t wallowed out.
- CGI Estate Collection horizontal rollers develop hard rolling and eventual lock misalignment. The stainless steel tandem roller housing corrodes at the axle point where salt deposits accumulate in the track; the sash then cocks and stresses the keeper. We pull the sash, measure the roller bore with a digital caliper, and install a matched replacement - not a universal roller - then re-square the frame before the lock test.
- CGI WinGuard vinyl frame corners weep water during driving rain. The fusion-welded corner gusset develops micro-separation after thermal cycling, which is more common in Lantana than inland Palm Beach County due to the temperature swing between afternoon sun and evening seabreeze. We disassemble the corner, inject two-part structural epoxy, and re-clamp rather than seal over the symptom with surface caulk.
- Impact-rated laminated glass in CGI Sentinel double hungs develops edge delamination. The PVB interlayer separates at the perimeter where the glass sits in the glazing pocket, usually from blocked weep holes trapping moisture against the edge. We document the delamination with photos for any warranty consideration, then replace the insulating glass unit with the correct CGI-specified laminated lite - not a generic impact glass - and verify the weep system is open before re-glazing.
- CGI Estate Collection entry door multi-point locks fail to engage the deadbolt. The gearbox strips internally after the homeowner compensates for a sagging door by over-torquing the handle; the real cause is usually hinge screw pull-out in the composite jamb from Lantana’s humidity cycling. We replace the gearbox with the correct Hoppe or Fuhr spec per the door’s birthdate stamp, then re-anchor the hinges with longer structural screws into the framing - not just the jamb.
Our CGI Impact Windows & Doors Process
- 1
Measured survey. We record every rough opening to the sixteenth, note the series and birthdate stamp from the existing frame, and check the glazing label for the design pressure rating. You keep this document.
- 2
Diagnosis and parts decision. We identify whether the failure requires OEM CGI parts - which we source through verified distribution - or a quality aftermarket equivalent that won’t void any remaining warranty. We note this in writing.
- 3
Written scope and price. The quote matches the measured survey line for line. No change orders. No “once we open it up” surprises.
- 4
Installation by verified crew. Our technicians arrive uniformed with license numbers visible, install per CGI’s fastening pattern for the specific design pressure, and photo-document every phase.
- 5
Operational test and evidence package. We cycle every sash, test every lock, and verify the weep system. You receive the photo record and the 365-Day Done Right Promise stamped under Haven Clause 5: No surprises.
- 6
Cleanup and final walk. We leave the work area as we found it, with the written warranty and the documented photo record in your hand before we leave.

Why Lantana Homeowners Call Sightline Windows & Doors Lantana for CGI Work
We are independently owned and operated under the Haven Standard, not a franchise or a commission-driven sales operation. Every CGI job we take in Lantana is backed by the 365-Day Done Right Promise - if it’s not done right, we make it right - and leaves a documented photo record as standard evidence, not an upsell.
Our crew knows the difference between a Sentinel balance shoe and an Estate roller bore because we have replaced hundreds of each in Palm Beach County homes, including the salt-exposed properties along Lantana’s beachfront corridor where corrosion accelerates. If your opening requires a different performance tier or price point, we also specify PGT, CWS, ES Windows, and ECO Window Systems - matched to what the opening requires, not what is in stock.
Live phone coverage is available 24/7. The person who answers can schedule your measured survey and will tell you when to expect the written quote.
FAQs
No - as an independent CGI service provider, we use OEM or warranty-safe equivalent parts and document every step with photos. If your CGI product is still under manufacturer’s warranty, we flag any eligible claims before work begins so you don’t pay for covered failures. Call (561) 461-2062 and we will review your warranty status during the free estimate.
If the frame is square, the glazing pocket is intact, and the failure is isolated to hardware or glass, repair is usually the right call; if the frame has corner separation, wallowed balance tracks, or design pressure inadequacy for current codes, replacement is the honest recommendation. We make this distinction during the measured survey and put it in writing. Call (561) 461-2062 to schedule yours.
Most single openings are completed in one day once parts arrive; full-home CGI replacements in Lantana typically run 2-4 days depending on opening count and whether stucco or siding repair is needed. We give you a written schedule with the quote, not a range. Call (561) 461-2062 for a timeline specific to your job.
Yes - we record the color code from the frame stamp during the measured survey and order factory-matched finishes from CGI’s current palette or verified archived codes. If the original color is discontinued, we document the closest match in writing before ordering. Call (561) 461-2062 to schedule your survey.
We provide a free second opinion on any written estimate - bring us their scope and we will review it line by line at no charge, noting any missing fasteners, incorrect design pressure ratings, or unspecified glazing specs. No obligation. Call (561) 461-2062 to set up the review.
Sonia Raman picked up her first glazing tools in a continuing education program at Los Angeles Trade-Technical College, where she learned to read a rough opening before she learned to drive on the freeway. She has spent the better part of two decades measuring, ordering, and installing windows and doors across South Florida, with her crew logging work on homes along the Lantana beachfront corridor that face salt air and hard summer storms every year. She is known for writing 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. Measure it right the first time. Everything after that is just paperwork.
