CGI Sliding Glass & Patio Doors in Sarasota: What to Know First
We provide independent CGI sliding glass and patio door repair, parts replacement, and full door swaps in Sarasota, with most track and roller jobs completed in a single visit. As an independent CGI service provider, we quote work by the job, not by the hour, and we tell you before we start what it will cost. If you own a CGI slider in Sarasota that binds, drags, or no longer seals, call (941) 214-2069 and we’ll walk through what you’re seeing before we ever send a truck.

This page is for CGI owners in Sarasota, Siesta Key, Lakewood Ranch, Palmer Ranch, and the surrounding Gulf Coast communities who want straight answers about what goes wrong with these doors, what it takes to fix them, and what the work should cost.
Key takeaways:
- We service and replace CGI sliding glass and patio doors across Sarasota without voiding the manufacturer warranty.
- Most roller, track, and lock repairs are one-visit jobs.
- We register every warranty layer in writing before the truck leaves your driveway.
- You’ll get a line-item quote on paper before any work begins.
How CGI Products Fail - and How We Fix Them
CGI builds a serious impact door. That’s why so many Sarasota condos and waterfront homes carry them. But even a well-built door lives its whole life in salt air, and the failures we see on the Gulf Coast follow a pattern worth knowing before you pay for the wrong fix.
- Roller assembly collapse on the Estate Collection sliders. The nylon rollers CGI uses on Estate Series doors are smooth-riding for years, but the bearings are not sealed. Once Gulf salt works into the housing, the roller stops rolling and starts sliding. The door goes from one-hand operation to a two-hand shove in a season. We replace the full roller assembly with sealed-bearing units rated for marine exposure, not just the wheel.
- Track wear on heavier Centennial and Estate panels. A CGI impact panel can weigh well over 200 pounds. When a roller flattens, that weight drags the stainless track cap and grooves it. Sometimes we can cap the track. Sometimes a deep groove means replacing the track section. We’ll show you the wear with a straightedge before we quote either way.
- Interlock weatherstripping that hardens in the sun. CGI uses a vinyl interlock in the meeting stile of many sliding models. After seven or eight years of southwestern exposure in Sarasota, that vinyl loses its flex and the door starts leaking air where the panels meet. You can buy generic replacement pile, but it pulls out. We use a durometer-matched extrusion that stays seated.
- Lock stile misalignment on doors that have settled. Sarasota slab homes move. When the slab settles a quarter inch, a CGI slider’s lock throw no longer seats in the keeper, or worse, the multi-point rods jam halfway. Forcing the handle bends the rod. We correct the panel alignment first, then adjust the lock linkage. Replacement hardware rarely solves that particular problem.
- Water intrusion at the bottom track weep system. CGI tracks have weep holes designed to drain storm water that gets past the outer barrier. When those weeps clog with sand and shell grit, water sits in the track, then works under the door. On Sarasota barrier-island homes we clean and, where needed, ream those weeps as part of any track service.
Our CGI Sliding Glass & Patio Doors Process
We’ve been doing glass work long enough to know that a door repair is only as good as the diagnosis that came before it. Here’s how a CGI job runs with us in Sarasota.
- 1
You call (941) 214-2069. A live person answers, 24/7. We ask what the door is doing, which brand it is, and when it started.
- 2
We visit. A background-checked, uniformed technician arrives at the scheduled time. We inspect the panel, rollers, track, lock, and frame. Every opening gets measured twice.
- 3
We show you what we found. You’ll see the worn roller or the grooved track before we quote anything. We’ll explain the OEM part option and any quality aftermarket alternative that makes sense for a Sarasota door.
- 4
We quote on paper. Line items, no surprises, no change orders invented mid-job. You approve before a single part is ordered.
- 5
We fix it. Most CGI roller, track, and lock work is done in one visit. We test the door through full travel three times before we’re done.
- 6
We register the paperwork. Both manufacturer warranty layers get registered in writing before the truck leaves. If the pane isn’t true, the job isn’t done.
What CGI Sliding Glass & Patio Doors Costs in Sarasota
CGI door work in Sarasota is generally higher than non-impact door work because the panels are heavier, the hardware is impact-rated, and the parts are not the cheapest thing on the shelf. Here’s what we typically see.
| Work Type | Typical Range in Sarasota |
|---|---|
| Roller assembly replacement (one sliding panel) | $180-$340 |
| Track cap replacement / repair | $220-$400 |
| Lock hardware repair or replacement | $160-$310 |
| Weatherstripping and interlock replacement | $150-$280 |
| Full CGI slider replacement (impact-rated, installed) | $3,200-$7,500 depending on size and series |
What moves the price: panel size and weight, how long the door has been running on failed rollers, whether the track is salvageable, and whether we’re matching existing hardware or replacing the full set. Every estimate is free, written, and itemized. Call (941) 214-2069 and we’ll give you an honest number for what you’re dealing with.

Why Sarasota Homeowners Call TruePane Windows & Doors for CGI Work
Dale Kessler founded this company because he kept seeing the same thing on Gulf Coast jobs: out-of-true installs, voided warranties, and homeowners who couldn’t get anyone back on the phone. That’s why we run every CGI job through The Keystone Standard. Both warranty layers registered in writing, durations stated, before the truck leaves your driveway.
Our 90-Day Done Right Promise says if it’s not done right, we make it right. No paperwork fights, no fine print. We also work across the major impact lines you’ll find in Sarasota, including PGT, CWS, ES Windows, and ECO Window Systems, so when a door needs parts, you’re not stuck waiting on one supply channel. We’ve been serving this community for over 42 years, and we plan to be here in thirty more.
FAQs
Yes. We follow CGI’s warranty-safe service practices and document all parts and labor so your factory coverage remains intact. We also register warranty layers in writing as part of The Keystone Standard. Call (941) 214-2069 if you want us to look at what’s covered before any work starts.
We quote OEM first and offer quality aftermarket alternatives where they genuinely make sense for a Sarasota door. Sealed-bearing rollers made for marine environments often outlast the original nylon units, and we’ll show you the difference on paper before you decide.
For a door that won’t secure, we treat it as priority work and a live person answers 24/7, so you’ll reach someone the moment you call. Most roller, lock, and track repairs are completed in a single visit once we’re at the home.
That depends on the frame, the track, and the glass. If the frame is square and the insulated glass is still sealed, repair is usually the better money. If the track is grooved deep or the frame has shifted, replacement starts making sense. We’ll show you both numbers and let you decide.
Yes, and it’s the main reason we see roller bearing failures on barrier-island homes years earlier than in inland neighborhoods. If your door sits within a mile of the Gulf, expect shorter hardware service intervals unless sealed-bearing components are installed. We routinely swap in marine-rated hardware on Sarasota coastal door jobs.
If you own a CGI slider in Sarasota and it’s dragging, binding, or failing to seal, call (941) 214-2069 to schedule your free estimate. We’ll look at the door, tell you what it needs, and put the price on paper before you commit to anything.
