CGI Windows & Doors in Bonita Springs, FL

CGI Windows & Doors in Bonita Springs, FL | Winslow Windows & Doors

We provide independent CGI window and door service across Bonita Springs, from single-hung rebalancing to full canal-front slider rebuilds. What makes our CGI work different here is simple: we’ve been retrofitting these exact units through three Lee County code cycles, including the post-Ian surge that exposed which CGI models hold up on salt-laced canal homes and which ones fail early. Call (239) 899-6411 and you’ll get a straight answer from someone who’s actually worked on CGI frames in Bonita Bay, Pelican Landing, and the older streets near Old Bonita Springs. CGI sales & service is core to what we do, and we’ve been doing it since 2011 with Ed Winslow’s name on every truck.

Why Bonita Springs Residents Choose Us for CGI Service

Impact Windows in Bonita Springs like CGI’s are built for Florida’s wind codes, but the salt air moving through Bonita Springs’s canal networks punishes hardware in ways a spec sheet never mentions. We know which components corrode first, which weep-hole patterns clog, and which frame anchors loosen under repeated uplift cycling. That knowledge comes from actual service calls, not a training manual. Ed Winslow grew up in Miami and learned the trade at Miami Dade College’s construction technology program before spending decades in the field. He still visits every Bonita Springs job site at least once, not to supervise, but because he wants to see how the light falls through a finished opening. Our techs work on CGI 9000 Series, Estate Collection, Classic Series, and 3000 Series units every month. We’re local, we answer the phone around the clock, and every tech arrives background-checked and in uniform. You know who’s at your door before the truck parks.

Common CGI Windows & Doors Problems We Solve in Bonita Springs

• Corroded horizontal rollers on canal-side sliders. The CGI 9000 Series uses stainless steel rollers, but Bonita Springs’s salt-laden air off the Imperial River canal network pits and seizes them within 3 to 4 years. We swap in marine-grade rollers and resurface or replace the track while preserving the frame’s wind-load rating.
• Warped sashes and broken balance springs on single hungs. The CGI Estate Collection is a solid window, but repeated wind-load cycling during post-Ian storms fatigues the balance springs and can warp sashes that weren’t shimmed perfectly at original installation. We rebalance or replace the spring cartridge and realign the sash, or advise replacement if the warp is structural.
• Weep-hole clogging and sill leaks on casements. CGI Classic Series casements rely on sill weep holes to drain water. In Bonita Springs, salt crust and windblown debris from canal exposures block those channels within a season or two, pushing water inward and staining stucco below the opening. We clean, flush, and where needed, modify the sill drainage to handle Gulf Coast salt loads.
• Frame-to-concrete anchor loosening on 3000 Series sliders. Older CBS homes across Bonita Springs, especially 1980s and 1990s construction, have CGI 3000 Series sliders anchored into masonry with fasteners that lose bite after years of high-velocity wind load. Post-Ian Lee County inspectors flag these. We reset frames with deeper masonry anchors and pass the uplift test.
• Chronic water intrusion on canal-facing three-panel units. In communities like Bonita Bay, canal-side sliders with standard aluminum frames show water intrusion within 5 to 7 years. The fix is flush-fin framing, stainless or marine-grade hardware, and seasonal weep-hole maintenance. We quote that work honestly, including what the HOA will and won’t approve.

CGI Service in Bonita Springs: What Local Conditions Mean for Your Equipment

Here’s the thing about Bonita Springs that doesn’t apply the same way in Fort Myers or Naples: this city runs a dual-approval gauntlet on nearly every CGI window or door replacement. Lee County tightened its post-Ian anchoring inspections considerably, which means any frame we set has to prove uplift resistance to the new standard. But at the same time, the architectural review boards in Bonita Bay, Pelican Landing, and Spanish Wells enforce their own specs on frame color, grid pattern, and even hardware finish. A homeowner can’t just hand us a product cut sheet for Bonita Springs Window Installation and say go. We have to match the HOA’s exact CGI color code and grid layout while also installing anchors that pass the county’s post-Ian test. That’s not how it works 20 minutes south in Naples. Our field techs carry HOA spec notes for the major Bonita Springs communities, and we’ve learned which CGI configurations the boards will approve without a fight. If you’re in Bonita Bay with a canal-facing wall, expect us to discuss flush-fin frames, stainless steel or marine-grade locks, and weep-hole maintenance as standard, not upsell.

One job that still sticks with us: a corroded CGI 9000 Series three-panel slider on a canal-front home in Bonita Bay. The original stainless steel rollers had seized, the track was pitted from salt air, and the frame had started pulling away from the concrete. We swapped in marine-grade rollers, cleaned the weep holes, reset the frame with deeper masonry anchors to pass the county’s uplift test, and the homeowner said it opened smoother than the day it was installed. That’s the kind of fix this market demands, and it’s the kind we do every week.

CGI Models & Products We Service in Bonita Springs

We service the full CGI lineup you’re likely to find in Bonita Springs homes: the 9000 Series horizontal roller, the Estate Collection single hung, the Classic Series casement, and the 3000 Series single hung. For structural components like rollers, locks, and balances, we use OEM CGI parts to protect the original wind-load rating, because aftermarket hardware on a structural component can void the product approval. But on canal-facing units where OEM stainless steel failed prematurely, we’ll switch to marine-grade aftermarket hardware that actually survives the salt exposure. We keep common rollers, springs, latches, and weep-hole fittings stocked for fast Bonita Springs turnaround, and Ed’s name is on the truck. That means we stand behind every frame we set.

FAQs - CGI Windows & Doors in Bonita Springs

Why do my CGI horizontal roller windows corrode so fast on my Bonita Springs canal home?

Bonita Springs sits at the mouth of an extensive private canal network feeding off the Imperial River and Spring Creek, which means salt-laden air moves across canal-facing walls on multiple exposures, not just the Gulf side. That salt settles on rollers, tracks, and weep holes, and the CGI 9000 Series stainless rollers begin pitting within 3 to 4 years. Marine-grade upgrades and seasonal weep-hole cleaning fix it. Call (239) 899-6411 for an exact diagnosis, estimates are free.

Can you match my Bonita Bay HOA’s exact CGI frame color and grid pattern?

Yes. We keep HOA spec notes for Bonita Bay, Pelican Landing, and Spanish Wells, and we order CGI frames to the exact color code and grid pattern each board requires. We also coordinate with the board on hardware finish so the install passes review the first time.

My CGI single hung windows won’t stay up after Hurricane Ian-what’s wrong?

That’s a classic Estate Collection balance spring failure. Ian’s wind-load cycling fatigued the spring cartridges in a lot of Bonita Springs single hungs, and some also warped the sashes. We replace the balance cartridge and realign the sash, or quote a new unit if the warp is structural. Call (239) 899-6411 and we’ll tell you which one it is.

Should I repair or replace my pre-2010 CGI sliders that are leaking water?

If the frame is sound and the sill corrosion is surface-level, we repair it. But pre-2010 frames with deeply corroded sills or cracked welds usually can’t be restored to hold a wind-load rating, and we’ll recommend full replacement. We won’t patch something that’s going to leak again next wet season.

Can you upgrade my old aluminum jalousie windows to CGI impact windows in Old Bonita Springs?

Yes. Many 1970s homes near Old Bonita Springs still carry original single-pane aluminum jalousies, and we replace them with CGI impact units anchored properly into the CBS masonry. We handle the anchoring to current Lee County standards and any HOA requirements if the property falls inside a gated community. Call (239) 899-6411 for a line-item quote.
