CGI Sliding Glass & Patio Doors in Sarasota: What to Know First
We repair and replace CGI sliding glass and patio doors across Sarasota as an independent CGI service provider, and most track-roller, lock, and weather-seal jobs wrap up in a single visit. Realistic pricing for CGI door work in Sarasota runs $220 to $480 for common repairs, while full door replacements start around $2,800 and climb based on glass package and panel count. If you own a CGI door that’s dragging, leaking, or refusing to lock, call (941) 267-0779 and we’ll give you a straight answer before anyone rolls a truck.

This page is for CGI owners who want someone who actually knows the product line, not a generalist who’ll learn on your door. Ed Winslow started this company in 2011, and we’ve worked CGI doors in neighborhoods from Siesta Key to Palmer Ranch to the North Trail ever since.
How CGI Products Fail - and How We Fix Them
- Sentinel and Estate series roller assemblies grinding or jumping track. We see this constantly in Sarasota, where wind-driven sand from Gulf breezes works its way into the bottom track and chews up nylon rollers. The door gets heavy, then it starts binding mid-travel. We pull the panel, clean the track channel completely, and install new tandem steel-bearing rollers. Done right, the door should glide with two fingers.
- Interlocking stile weather seal flattening out. CGI’s center-meeting interlock uses a compression seal that loses its memory after 8 to 10 years of Florida sun exposure, especially on west-facing lanais. You’ll feel a draft or see water wicking in during a hard afternoon squall. We replace the seal with a durometer-matched material so the panels still close flush, not something generic from a hardware store aisle.
- Multi-point lock bars falling out of alignment on HPG series patio doors. When the door settles or the header shifts slightly, the shoot bolts and hook bolts stop lining up with the keepers. The handle gets stiff, then won’t throw at all. We re-shim the panel and re-time the lock mechanism so all points engage together, which also keeps your CGI warranty intact where it still applies.
- Weep hole blockage causing water to pool inside the bottom track. CGI doors drain through a weep system in the sill, and in Sarasota those tiny channels pack up with pollen, salt crust, and fine sand within a few seasons. Water then overflows the interior dam and darkens your flooring. We clear the weeps mechanically, flush the sill, and check that the interior dam seal is still doing its job.
- Glass condensation between panes in original-build CGI doors. After 12 to 15 years, the factory desiccant inside a sealed unit can saturate, particularly in homes near the Intracoastal. You’ll notice fogging you can’t wipe away. We can often source a direct replacement insulated glass unit through our supply chain, and we’ll quote both OEM and equivalent-glass options so you can decide with numbers in hand.
Our CGI Sliding Glass & Patio Doors Process
- 1
Call (941) 267-0779. A live person picks up, day or night. We ask what the door is doing, what model it is if you know, and when it started.
- 2
Diagnostic visit. A background-checked, uniformed technician arrives and goes through the door methodically: track condition, roller wear, lock timing, seal compression, and sill drainage.
- 3
Straightforward quote. We tell you what actually needs fixing versus what can wait. No manufactured urgency, no mystery line items.
- 4
Parts decision. We walk you through OEM-versus-aftermarket trade-offs honestly. Some CGI parts are worth the factory price. Others, like generic roller assemblies, perform identically for less. You decide.
- 5
The repair or replacement. We do the work, self-test everything, and clean the track and sill before we leave. You test the door with your own hand.
- 6
The 36500-Day Done Right Promise. If it’s not right, we come back and make it right. That’s the whole promise, and Ed’s name is on it.

What moves the price on a CGI door job in Sarasota: panel width, glass package (impact-rated laminated glass costs more than standard), whether the frame needs re-shimming, and parts sourcing. Salt-exposed homes near the water tend to need more hardware replacement than inland homes. Every estimate is free, and we’ll honor $40 off any repair over $200, plus a permanent 10% discount for seniors and veterans. Call (941) 267-0779 and we’ll price your exact door, not a generic average.
Why Sarasota Homeowners Call Winslow Windows & Doors for CGI Work
Because a CGI door is a serious investment, and guessing on repairs shortens its life. We’ve been serving Sarasota and Manatee counties since 2011, and Ed Winslow’s name is on the business, his published address is on the website, and his license number is there too. When you call at 2 a.m. during a storm, a live person answers, not a voicemail tree. Our technicians are background-checked and show up in uniform, so you know exactly who’s at your door before they knock. We’re also authorized installers for PGT, CWS, ES Windows, and ECO Window Systems, which means if your CGI door is beyond sensible repair, we can show you comparable impact-rated alternatives without starting your research over from zero.
FAQs
No, as long as the repair is done correctly with appropriate parts. As an independent CGI service provider, we’re careful to preserve warranty coverage where it still applies, and we’ll tell you before we start if a proposed fix could affect it. Call (941) 267-0779 and we’ll review your door’s status honestly.

Most common parts, like rollers, locks, and seals, are on our trucks or available within a few days. Specialized glass units may take two to three weeks from order to install. We’ll give you a realistic timeline on the diagnostic visit, not after you’ve paid a deposit.
Repair makes sense if the frame is solid, the glass is clear, and the issue is hardware-related, which covers most of what we see. Replacement makes sense when the frame is corroded, the glass package is compromised, or energy performance has dropped to the point where you’re paying for it monthly. We’ll show you the numbers for both and let you decide.
Yes, we work throughout Sarasota including Siesta Key, Lido Key, Bird Key, Palmer Ranch, and the North Trail. Salt air accelerates hardware wear out there, so we see more roller and lock failures on the islands, and we stock the parts those doors tend to need. Call (941) 267-0779 and we’ll get you scheduled.
Always. We use upfront pricing with no change orders, and if you already have a written estimate from another company, we’ll give you a free second opinion on it. You’ll know the number before we touch a screwdriver. Estimates are free, so there’s no reason to guess at what a CGI repair should cost.
If your CGI sliding glass or patio door is giving you trouble, don’t wait for the next storm to find out how bad it really is. Call (941) 267-0779 for a free estimate, and you’ll talk to a real person who knows CGI doors and knows Sarasota. The one down the road.
