CGI Windows & Doors has been a staple in Florida coastal construction for decades, and their impact-rated product lines are common throughout Boynton Beach’s condo communities and single-family neighborhoods, with similar demand for Cgi in Delray Beach. The Series 1300 single hung, Series 900 sliding glass door, Series 400 horizontal roller, and Series 7000 vinyl impact window all appear regularly in local buildings, particularly in the 55+ communities like Century Village where original aluminum frames from the late 1970s and early 1980s are being upgraded to modern impact-rated systems. We are an independent service provider - not affiliated with, authorized by, or sponsored by CGI - which means we work for the homeowner, not the manufacturer, and our recommendations are based on what the opening actually needs.

Our experience with CGI products in Boynton Beach runs deep. We’ve replaced corroded rollers in Intracoastal-facing units where salt air had destroyed the original hardware in under five years. We’ve resealed hairlined impact glazing before storm season turned a corner seal into interior water damage. And we’ve walked countless homeowners through condo association submittal packages, because in Boynton Beach, board approval often precedes permit approval.

Why Trust Sightline Windows & Doors Boynton Beach for Your CGI Windows & Doors?

Sonia Raman, who leads our operation, grew up in Miami and learned glazing and frame installation through the building trades program at Miami Dade College before spending two decades on actual job sites. She and our crew have worked throughout Boynton Beach for years, including residential retrofits along the streets bordering Intracoastal waterways near Boynton Harbor Marina where salt air and wind load specs leave no margin for guesswork. She measures twice before any order is placed. She walks homeowners through every line of a quote until there are no open questions. And she keeps a running list of every window she’s ever had to pull and replace because a previous installer used the wrong sealant - it’s longer than she’d like, and it’s the reason she checks her own crew’s caulk joints before any truck leaves a site.

That field discipline translates directly to how we handle CGI products. We know the difference between CGI’s original equipment rollers and the generic hardware that some suppliers pass off as compatible. We understand how CGI’s impact glazing sealant behaves at the sash corners after four or five Boynton Beach summers. And we know that “Measure it right the first time and the install is already half done” - which is why our measured survey and your written quote are the same document, with no change orders waiting to surprise you later.

Every technician on our CGI jobs is background-checked, uniformed, and identified by license number before arrival - Haven Clause 3, Verified Crews. Every completed job leaves a documented photo record. And every engagement is governed by the Haven Standard: Have it in writing, Arrive on schedule, Verified crews, Evidence on every job, No surprises.

Common CGI Windows & Doors Problems We Fix in Boynton Beach

• Felt-and-fin weatherstripping failure on CGI Series 1300 single hung units. The original felt strip on older CGI single hung windows compresses and pulls away from the sash after years of Florida heat and salt-air exposure. Once the seal gaps, wind-driven rain pushes directly onto the interior sill, and the salt air that Boynton Beach’s Intracoastal location guarantees starts working on the aluminum finish underneath. We replace the flattened felt with EPDM or silicone weatherseal rated for coastal exposure, and we check the sash balance while we’re in the frame.
• Corroded and flat-spotted rollers on CGI Series 900 sliding glass doors. The original roller assemblies on CGI Series 900 doors are not stainless, and in Boynton Beach’s humidity they corrode, seize, and develop flat spots. The panel drags, jumps the track, or won’t reach the jamb far enough to let the latch engage. We’ve seen homeowners force the door until they bent the handle mechanism. Our fix: pull the operating panel, replace the roller assemblies with stainless units, clean and lubricate the track, and adjust the panel for proper glide and positive latch engagement.
• Impact glazing sealant hairlining at sash corners. The structural silicone sealant that bonds CGI impact glass to its frame dries and micro-cracks over time, starting at the corners where thermal expansion stress concentrates. In Boynton Beach, afternoon thunderstorms test these seals weekly during summer. The first sign is a cloudy or foggy edge on the glass; the next sign is water weeping through during a driving rain. We catch this in inspection and reseal before the glazing unit loses its integrity.
• Vinyl sash and frame weld separation on CGI Series 400 horizontal rollers. The heat-welded corners on CGI horizontal roller sashes can separate slightly at the sill, particularly if the unit has been racked by repeated operation on damaged rollers. The operating panel tilts, loses its square, and the weatherstrip no longer meets the frame evenly. We assess whether the sash can be squared and re-welded or if replacement is the honest call.
• Hardware and lock mechanism corrosion. CGI’s original hardware is functional but not always coastal-grade. Lock mechanisms, keepers, and tilt latches on single hung and double hung units seize or corrode in Boynton Beach’s salt-laden air. We stock stainless and coastal-rated replacements that match the original function with longer service life.

CGI Parts & Our Repair-vs-Replace Approach

We use OEM-equivalent or better replacement parts for CGI systems - correct-profile rollers, stainless hardware, and EPDM or silicone weatherseal rated for coastal exposure - rather than whatever generic part fits loosely in the frame. Our Boynton Beach warehouse stocks the roller assemblies, weatherstrip profiles, and hardware kits that CGI units in this market actually need, and we also keep inventory for CGI Windows & Doors in Lantana, FL, which means most repairs don’t wait on shipping.

The repair-vs-replace decision is straightforward: if the CGI frame is structurally sound and the glazing unit is intact, we repair. If the frame is corroded through, the impact glass seal is compromised across the full perimeter, or the sash weld has separated beyond reliable reassembly, we tell the homeowner honestly that replacement makes more sense than chasing a repair that won’t last. No upsell. No pressure. Just the documented condition and a written price for either path. Call (561) 421-3844 and we’ll inspect your unit and give you both options in writing.

Our CGI Service Process - Step by Step

1. 1
   Diagnosis with measured documentation. Our technician arrives with license number visible, inspects your CGI unit, and documents frame readings, sightline measurements, and product specs. You receive a copy of the measured survey. We identify the series, the failure mode, and whether repair or replacement is the sound recommendation.
2. 2
   Written scope and price before any work starts. Haven Clause 1: the measurement and the quote are the same document. You review every line item. No verbal estimates, no “we’ll figure it out as we go.”
3. 3
   Repair or install with OEM-equivalent parts. We use the correct-profile parts for your CGI series - stainless rollers where the originals failed, coastal-rated seal where the felt flattened, proper glazing sealant where the corners hairlined. Our crew works clean and leaves no debris.
4. 4
   Functional testing and adjustment. Every repaired or installed CGI unit is operated through its full range: sash lift and tilt on single hungs, panel glide and latch on sliders, roller alignment on horizontal rollers. We adjust until the operation is correct.
5. 5
   Documented photo record and warranty. You receive photos of the completed work and the 365-Day Done Right Promise in writing. If it’s not done right, we make it right - stamped on every job under the Haven Standard.
