AfterCGI Impact Windows & Doors in North Palm Beach: What to Know First
We provide independent CGI impact windows & doors service in North Palm Beach, with most repair and replacement jobs scheduled within three to five business days and priced in writing before any work begins. Typical CGI single-hung or horizontal roller repairs run $280-$520; full-frame replacements with impact-rated units range from $1,800-$3,400 per opening depending on series and rough-opening condition. This page is for homeowners who already own CGI products and need a technician who understands the difference between a Series 375 snap-in balance failure and a Series 575 monolithic impact glass delamination - and who can source the correct parts without guessing. Call (561) 475-1246 to schedule your free measured survey.
How CGI Products Fail - and How We Fix Them
- Series 375 single-hung balance spring fatigue. The coil balance system in this entry-level vinyl line loses tension after 8-12 years in North Palm Beach’s salt-air environment, causing the sash to drop or stick. We measure the exact coil weight stamped on the hidden balance shoe - not the visible sash width - and install OEM-spec coils rather than universal retrofits that throw off the tilt-latch geometry.
- Series 575 horizontal roller track deformation. The aluminum track on this mid-tier line develops flat spots where the nylon rollers hammer the same path during repeated storm-panel storage and removal. We true the track with a field-leveling jig rather than replacing the entire sill, which preserves the factory drainage weep geometry and keeps the warranty intact.
- Impact laminated glass edge delamination in coastal exposures. CGI’s interlayer can separate 3-8 mm from the glass edge on east-facing units in North Palm Beach after 6-10 years of thermal cycling and UV saturation. We document the delamination depth with caliper measurement; if it exceeds 5 mm or reaches the sightline, the lite must be replaced - not resealed - to maintain impact certification.
- Series 870 fixed picture window sealant bond failure. The structural silicone between glass and frame on this high-end line can shear in older North Palm Beach homes with concrete-block settlement, particularly in Lakeside Park where slab-on-grade shifting is common. We cut the old bead, prime with manufacturer-specified adhesion promoter, and re-glaze with Dow 795 or equivalent - never generic bathroom caulk, which voids the Miami-Dade NOA.
- Multi-point lock misalignment on CGI French and sliding doors. The shoot-bolt and deadbolt systems on impact-rated door units drift out of plane when the frame subsides or the header flexes. We shim to the lock manufacturer’s strike tolerances - typically ±1/16 inch - rather than forcing the hardware, which is how the zinc castings crack and become unsourceable.
Our CGI Impact Windows & Doors Process
- 1
Measured survey. Sonia Raman measures every opening herself on the first visit. If the opening isn’t right, the window isn’t right - that’s where we start. The customer keeps the dimension sheet; it becomes the quote.
- 2
Diagnostics with documentation. We photograph the failure, record frame squareness with a digital level, and note the CGI series, date code, and any Miami-Dade NOA sticker. You get a copy.
- 3
Parts decision. OEM CGI hardware when available; verified aftermarket when lead times exceed two weeks or the OEM part is obsolete. We state the source and warranty implication in writing before ordering.
- 4
Repair or replacement. Crews arrive uniformed, background-checked, with license numbers provided in advance. Work follows the Haven Standard: Arrive on schedule, Verified crews, Evidence on every job.
- 5
Post-install testing. Impact units get operability, lock, and seal verification; we check U-factor and SHGC ratings against the original specification to confirm no downgrade occurred.
- 6
Photo record and warranty. Documented photo record delivered within 24 hours. The 365-Day Done Right Promise applies - if it’s not done right, we make it right, under Haven Clause 5: No surprises.

These are 2024-2025 ranges for the North Palm Beach market, where salt-air exposure and concrete-block construction create conditions we see repeatedly in Lakeside Park and along the Intracoastal. The written quote you receive before work starts matches these figures for typical conditions; rough-opening rot, header repair, or stucco remediation would be priced separately and in writing. Call (561) 475-1246 for your free measured survey - estimates are free, and we offer a free second opinion on any written estimate you bring us.
Why North Palm Beach Homeowners Call Sightline Windows & Doors North Palm Beach for CGI Work
We are independently owned and operated under the Haven Standard, not a franchise, and we do not carry CGI authorization - we are an independent CGI service provider. What we do carry is 18,000+ openings of documented experience since 2012, including years of retrofit work in North Palm Beach where older concrete-block homes needed full rough-opening corrections before a single new unit could go in. Sonia Raman learned the trade at Miami Lakes Educational Center and has spent two decades building a reputation for tight tolerances on impact-rated installations - the kind of fit that matters when a Category 4 storm tests the sealant line at 3 a.m.
Our eight manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - mean we specify by what the opening requires, not by what is in stock. If your CGI part is back-ordered, we can cross-reference performance specs and present alternatives with the same Miami-Dade rating. Calls are answered by a live person, 24/7. Every job leaves a documented photo record, and the 365-Day Done Right Promise is stamped on the scope, not offered as a courtesy.
FAQs
No - CGI’s limited lifetime warranty covers manufacturing defects regardless of who services the unit, provided OEM-spec parts and procedures are used. We document both. Call (561) 475-1246 if you need a warranty review alongside your repair quote.
Most repairs are completed in two to four hours on site; parts that must be ordered from CGI’s Florida warehouse typically arrive in five to ten business days. We schedule installation the day parts land, not the week after. Call (561) 475-1246 to check current lead times.
Yes - we pull the original color code from the frame extrusion or jamb sticker and order factory-matched finishes for Series 575 and 870 lines. Series 375 white and almond are typically in-region stock. Call (561) 475-1246 to confirm your color.
Repair when the frame is square, the glass is intact, and the failure is isolated to hardware or sealant; replace when delamination reaches the sightline, the frame has settled out of square by more than 1/4 inch, or the unit is pre-2010 and parts are obsolete. We state the condition and the math in writing. Call (561) 475-1246 for a free second opinion.
Yes - all full-frame replacements require Palm Beach County building permit and Miami-Dade product approval verification. We pull the permit, schedule inspection, and deliver the passed inspection card with your final photo record. The permit cost is listed in your written quote, not added later. Call (561) 475-1246 to start the process.
