CGI Windows & Doors in Bonita Springs, FL | TruePane Windows & Doors
We provide independent CGI window and door service throughout Bonita Springs, from hardware replacement on a 1990s condo slider to full Impact Windows in Bonita Springs tear-outs on canal-front homes. The thing that makes our CGI work here different is simple: we’ve been inside enough of these openings to know how salt air, storm pressure, and thirty-year-old aluminum frames fail together. Call (239) 326-9942 and we’ll walk you through what’s actually wrong before anyone picks up a tool.

TruePane Windows & Doors has worked on CGI product lines across Lee County for years, and our CGI sales & service work covers everything from Estate Collection casements to Targa horizontal rollers. We’re not manufacturer-authorized. We’re independent, which means we repair based on what’s right for your opening and your permit, not what a warranty quota says. If you live in Bonita Springs, from Old Bonita east of US-41 to the gated communities off Bonita Beach Road, we’re the crew that answers the phone when a post-Ian insurance letter lands in your mailbox.
Why Bonita Springs Residents Choose Us for CGI Service
Dale Kessler started TruePane in 2008 after years of setting and finishing windows in Ohio and then Southwest Florida, including a stretch of impact-glass replacements along Gulf Shore Boulevard in Naples that taught him exactly what salt air does to a poorly seated frame. That experience carries into every Bonita Springs Window Installation. We measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves your driveway.
What that means for your CGI windows: we stock OEM hardware for current-generation Targa and Estate lines, and we know which aftermarket parts actually hold interlock tolerances on impact-rated frames. Most Bonita Springs service calls are diagnosed and resolved in a single visit. You don’t get a callback form or a regional call center. You get a live person on the phone, 24 hours a day, and a technician in your home who treats the opening like it’s in his own mother’s house.
Common CGI Windows & Doors Problems We Solve in Bonita Springs
- White oxidation blooms on Estate Collection aluminum frames. The canal-heavy salt air in Bonita Springs, especially east of US-41 toward the Imperial River, accelerates aluminum corrosion at sill corners. We see this on 1980s and 1990s Estate windows that have never been resealed. Left alone, the frame loses structural seating and the seal fails.
- Seized horizontal rollers on CGI Targa sliders in pre-2004 homes. These units often still have their original track rollers, now locked solid from years of humidity and salt exposure. Even when the laminated glass is fine, the door won’t slide without dragging, and the delaminated weatherstripping lets wind-driven rain through during afternoon thunderstorms.
- Corroded crank operators and multi-point locking hardware on casement windows. Older Bonita Springs condos are full of 1990s CGI casements where the crank binds and the locking points no longer engage. Repair parts for that generation were discontinued, so this usually means a full hardware replacement or a sash replacement, not a quick grease job.
- Fogged insulating glass units in Bonita Bay and Mediterra. Fixed and picture windows from the 2000s start showing interior fogging at the 15-to-20-year mark as the seal fails. In a gated community with strict HOA aesthetic rules, you’re not just replacing the glass, you’re matching frame color, grid pattern, and mullion profile to the association’s standard.
- Worn interlock weatherstripping on early-2000s impact sliding doors. In a post-Ian insurance market, adjusters now inspect for exactly this. If the interlock doesn’t seal tight, wind-driven rain finds the gap. We replace the weatherstripping with OEM material and re-set the door so the interlock engages properly.
CGI Service in Bonita Springs: What Local Conditions Mean for Your Equipment
Here’s a fact about Bonita Springs that shapes this work more than almost anything else: Hurricane Ian made landfall just miles north of the city in September 2022, and it triggered the largest permitted window-and-door replacement surge in Lee County’s history. When a homeowner pulls a permit for a replacement, the new opening has to meet current Florida Building Code wind-load and impact standards, not the code the house was built to. In the older platted neighborhoods east of US-41 near the Imperial River, the pre-boom “Old Bonita” areas, that means homes that carried non-impact jalousie windows and single-track aluminum sliders through decades of storm seasons are now being forced into fully impact-rated assemblies, one permit at a time. That concentrated retrofit pocket doesn’t exist in Naples or Estero, where Ian’s footprint was lighter and the trigger was less aggressive.
For a CGI owner, this matters in two directions. If you’re in an older Bonita Springs home, your existing openings may not be code-compliant anymore, even if they’ve never leaked. And if you’re replacing them, the product you put in has to carry third-party impact certification rated for 150+ mph, because Bonita Springs sits inside Florida’s highest design-wind-speed corridor. We’ve handled enough of these permit-driven jobs to know what the inspector will check and what the HOA will flag. In the Old Bonita neighborhood just off Dean Street, our tech pulled a pair of original non-impact single-track sliders from a 1987 canal-front cottage after the homeowner got an insurance-driven permit notice. We replaced them with CGI Targa horizontal rollers rated for 150+ mph, including new stainless rollers and interlocking weatherstripping, and added a new impact-rated CGI entry door to close out the permit. The change was so airtight the homeowner said the AC finally stopped running all day.
CGI Models & Products We Service in Bonita Springs
We work on the full CGI lineup that shows up in Bonita Springs homes: the Estate Collection, Targa by CGI, Estate Casement, Estate Fixed, and the 7600 Series Impact Window. Current-generation Targa and Estate hardware we keep in stock for fast turnaround. Older discontinued CGI hardware we source carefully, using OEM parts wherever they’re still manufactured and proven aftermarket replacements only where function holds up. On impact-rated frames, aftermarket gaskets rarely match the interlock tolerances, so we don’t cut that corner. When corrosion is widespread or the unit predates current FBC impact standards, we’ll tell you straight that a full sash or door replacement is the better long-term fix.
CGI Service Pricing in Bonita Springs
CGI service pricing in Bonita Springs depends on what failed and how long it’s been failing. A simple hardware rebuild on a current-generation Targa slider runs less than a full sash replacement on a 1990s Estate casement with discontinued parts. What drives the cost here is salt-air corrosion, permit requirements, and HOA finish matching, not the manufacturer’s list price. Every free estimate includes a written line-item quote on paper, so you see exactly what you’re paying for before any work starts. We don’t change the number once work begins. Call (239) 326-9942 for an exact quote, estimates are free and there’s no obligation.

FAQs - CGI Windows & Doors in Bonita Springs
It depends on whether the crank mechanism is the only failure or the frame itself is corroded and losing structural seating. The crank and multi-point locking hardware on 1990s CGI Estate casements were largely discontinued, so repair parts are scarce. If the frame is sound and the sash still seats, we can often rebuild the hardware with quality aftermarket replacements. If the corrosion has spread into the frame corners, the sash needs replacing. Either way, we’ll show you the opening and explain the options before we quote. Call (239) 326-9942 for a free assessment.
The short answer: if the windows were installed before 2004, they likely don’t. Bonita Springs sits inside Florida’s highest design-wind-speed corridors, and current Florida Building Code requires third-party impact certification rated for 150+ mph. Windows installed to older code don’t carry that rating. If you’ve pulled a permit for any work or filed an insurance claim that triggered a code review, the inspector will check the product approval. We can help you confirm what you have and what a compliant replacement looks like.
Yes, and we take HOA finish requirements seriously because they’re non-negotiable once the association reviews the permit. CGI offers a range of frame finishes, grid profiles, and mullion configurations, and we’ll pull the HOA standard before we quote so the replacement matches on paper and in the opening. If the association has already approved a specific CGI configuration, we’ll work within it. If not, we’ll help you get the paperwork lined up.
Often, yes. The most common cause in Bonita Springs is a seized horizontal roller combined with delaminated or missing interlock weatherstripping. We can replace the rollers with stainless hardware, install OEM weatherstripping, and re-set the panel so the interlock engages properly. If the frame is badly oxidized or the track is bent from years of forcing the door, that’s a different conversation. But we’ll always try the repair that solves the problem first. Call (239) 326-9942 to schedule a look.
We service CGI windows and doors regardless of who installed them. Most of our Bonita Springs CGI service calls are on homes we didn’t originally touch, and in post-Ian retrofits, the previous installer is often long gone. We’re independent, so we repair based on condition and code, not warranty history.
