CGI Windows & Doors in Sarasota, FL | TruePane Windows & Doors
We provide independent CGI windows and doors service across Sarasota, from Gulf Gate to Gillespie Park to the barrier islands. We’re not a CGI factory affiliate, and that’s the point: we tell you what needs fixing, what needs replacing, and what’s still got life in it, without a sales quota behind the answer. If you’ve got a CGI window or door acting up, call (941) 214-2069 and we’ll take a look.

The one thing that makes our CGI work different in Sarasota is that we’ve spent years taking apart failed CGI assemblies in mid-century modern houses and salt-exposed condos. We know how their roll-form frames, glazing beads, and balance systems behave under Florida loads because we’ve seen them fail up close. That knowledge comes from field work, not factory training manuals.
Why Sarasota Residents Choose Us for CGI Service
CGI is a Florida product, built in Miami, and it’s designed with hurricane zones in mind. But “designed for Florida” and “designed for Sarasota” are not the same thing. Salt air off the Gulf, single-pane jalousie replacements in 1950s block homes, and Paul Rudolph-era glass walls all put different demands on CGI hardware than a suburban Orlando install would. Our crews have worked these specific jobs long enough to know what fails first and why.
Dale Kessler founded TruePane in 2008 after growing up in his father’s glass shop in Columbus, Ohio, cutting lites and setting frames before he could drive. He sharpened that at Columbus State Community College with a grounding in building systems and construction technology. For the better part of two decades he and our crew have worked the Gulf Coast, including full window and door replacements along the Siesta Key corridor where salt air and storm exposure make a sloppy install a real liability. He reads a rough opening the way other people read a room: he catches what’s off before the first piece of glass is unloaded. That’s the standard our Sarasota CGI service runs on, and it’s why our CGI sales & service work carries a 90-Day Done Right Promise, not a fine-print shrug.
We also answer the phone. A live person picks up 24 hours a day, seven days a week. Not a voicemail tree, not a callback form. If your CGI slider just started binding, you talk to a person who can tell you what to check before we send a truck.
Common CGI Windows & Doors Problems We Solve in Sarasota
Here’s what we run into most often on CGI equipment in Sarasota, and what’s usually behind it:
- Powder coat peeling and aluminum pitting on barrier island installations. On Siesta Key, Longboat Key, and Casey Key, salt air off the Gulf corrodes standard aluminum frames within three to five seasons. The powder coat starts lifting at the corners, then pitting sets in. We replace with marine-grade alloys or fiberglass frames when the damage is structural, and repair when it’s cosmetic.
- Roller assemblies binding on CGI horizontal sliders and patio doors. Sand gets into the lower track, grinds against the rollers, and eventually the door feels like it’s dragging a cinder block. We’ve seen this on almost every beachside CGI Sentry Series horizontal roller we’ve serviced. We pull the panel, clean or replace the rollers, and re-set the track so it closes square.
- Spiral balance springs losing tension in CGI single hung windows. This is the classic “sash drops suddenly and won’t stay up” complaint. In Sarasota, the salt accelerates the corrosion on the balance springs even on the mainland side. We swap in stainless aftermarket replacements that outlast the originals.
- Vinyl glazing beads cracking around impact laminated glass. Sarasota’s seasonal thermal expansion, hot days, cool Gulf nights, does a number on the vinyl beads that hold impact glass in place. They crack, then the seal starts to go. We replace the beads and re-bed the glass before water gets where it shouldn’t.
- Water intrusion through the sill on older CGI Classic Series sliding doors. Once the sill flashing or weep holes fail, water finds its way in. In South Gate and Gulf Gate block homes where the original install was done decades ago, this is often a full sill replacement or a unit swap, not a patch job.
Dale’s signature phrase applies to every one of these: if it’s not square and it’s not sealed, the rest of the conversation is going to be expensive.
CGI Service in Sarasota: What Local Conditions Mean for Your Equipment
Sarasota’s Paul Rudolph-era homes used custom, ultra-slim aluminum sliding glass walls with sightlines no modern off-the-shelf impact unit replicates. That’s not an exaggeration: the Sarasota School of Architecture built hundreds of houses in the 1950s and 1960s around floor-to-ceiling glass and vanishingly thin frames. When those original systems fail, or when a homeowner needs Impact Windows in Sarasota, a CGI retrofit job often requires coordinating with custom fabricators and sometimes Sarasota County historic preservation staff before a permit is issued. A window company relocating from another Florida market consistently underestimates this. We don’t, because we’ve done it. If you own a mid-century house in South Gate or Gillespie Park and you’ve been told “just put a standard impact window in,” get a second opinion. Getting the sightlines right without compromising the code compliance or the architectural character is a workflow most companies never learn.
This is the one thing neither a generic CGI page nor a generic Sarasota service page will tell you: replacing those slim-profile original glazing systems with Florida Building Code-compliant impact units without destroying the proportions that make these homes significant is a specific skill. It’s the reason we stock marine-grade aftermarket hardware for discontinued CGI models and have relationships with local fabricators who can match sightlines.
CGI Models & Products We Service in Sarasota
We service the full CGI line that shows up in Sarasota homes: the 950 Series single hung, the Estate Collection casement, the Sentry Series horizontal roller, and the Classic Series sliding glass doors. For current models, our Sarasota Window Installation team uses genuine CGI replacement parts ordered through our distributor network. For discontinued models, we use marine-grade aftermarket hardware that meets or exceeds the original spec. The parts that get replaced most often in Sarasota, balances, rollers, weatherstripping, glazing beads, are kept stocked locally so we’re not waiting on a freight truck when your sash is sitting on the floor.
CGI Service Pricing in Sarasota
CGI service on the Gulf Coast runs on a few things: whether the part is genuine or aftermarket, how much salt corrosion we’re working through, and whether it’s a repair or a full sash replacement. Here’s the honest pricing picture for Sarasota:
- Balance replacement on a CGI 950 Series single hung: $120-$240, parts and labor, depending on whether one or both balances are shot.
- Roller assembly replacement on a CGI Sentry Series horizontal roller: $140-$280, depending on whether the track also needs re-setting.
- Glazing bead replacement and glass re-bedding: $90-$180 per sash.
- Full sash replacement on a CGI impact window (950 Series): $350-$650, depending on size and glass package.
- Full-frame CGI impact window replacement in Sarasota: $1,100-$2,400 per opening, installed, depending on the size, the frame condition, and whether we’re coordinating with historic preservation on a Rudolph-era house.

FAQs - CGI Windows & Doors in Sarasota
Can you upgrade my 1970s Sarasota School glass wall with CGI impact sliders without ruining the original sightlines?
Yes, in most cases we can, though it depends on the specific opening and what the county will permit. We’ve done retrofit work on mid-century homes where the original frames were custom-fabricated with sightlines no standard impact unit matches. The approach is to use a CGI slider with the slimmest available profile and coordinate with a local fabricator for any custom trim or mullion work. On historically designated properties, we work with Sarasota County preservation staff before the permit is filed. Call (941) 214-2069 for a free assessment of your specific glass wall.
Why is the powder coat peeling off my CGI windows on Siesta Key after only four years?
Salt air off the Gulf is the culprit. Siesta Key sits in Exposure Category D coastal zone, and the constant salt spray attacks the powder coat finish far faster than the manufacturer’s inland warranty assumptions. Once the coating starts lifting, pitting follows, and the frame can degrade quickly. We repair cosmetic corrosion where possible, but if the frame is structurally compromised, we recommend full-frame replacement with marine-grade alloy or fiberglass. We’ll tell you straight which one your windows need. Estimates are free.
My CGI horizontal roller patio door is sticking only during the summer. Is that normal in Sarasota?
It’s common, but not normal in the sense of “leave it alone.” Sarasota’s summer heat expands the frame and track materials, and when you add sand and salt residue to the lower track, the rollers can’t do their job. The door binds. If it’s only sticking seasonally, we can often fix it with a thorough track cleaning, roller replacement, and a track re-set. If we see pitting or warping, we’ll tell you the repair isn’t going to hold and recommend replacement. Call (941) 214-2069 for a free estimate.
Do I need full frame replacement or can we use inserts for my CGI impact windows in a South Gate block home?
Inserts work only when the existing frame is still square, uncorroded, and properly flashed. In South Gate’s 1950s and 60s block homes, we often find the original window frames are still structurally sound but have lost their weatherstripping or have minor corrosion. In those cases, inserts are the right call and cost significantly less than full-frame replacement. If the frame is pitted, out of square, or leaking at the sill, inserts won’t fix the underlying problem. We’ll measure, inspect, and tell you which option fits your situation before we quote anything.
Can you repair a CGI double hung where the sash suddenly dropped and will not stay open?
Yes. That sudden drop is almost always the spiral balance springs losing tension, which is a common failure in Sarasota’s salt-rich air. We remove the old balances, install stainless aftermarket replacements, rebuild the jamb liners if needed, and adjust the sash so it closes dead-square. The repair typically runs $120-$240 per window depending on how many balances need replacing. Call (941) 214-2069 for an exact quote, estimates are free.
