This page is for homeowners in Miami Springs who already have CGI sliding doors or are pricing them for replacement and want straight answers from people who work on them every week, not a sales script.

How CGI Products Fail - and How We Fix Them

CGI builds a rugged door, but Miami Springs weather and daily use find the weak points. Here’s what we actually see in the field:

• Sentinel series rollers flattening under salt air. The single offset roller design on older Sentinel sliders was never built for the salt-laden air that drifts inland from the coast. The nylon wheel develops a flat spot, then the door rides metal-on-metal and gouges the track. We replace the roller assembly with a sealed-bearing version that handles the Miami Springs humidity without the same wear curve.
• Estate series interlock corrosion at the meeting rail. The interlocking stiles on Estate sliders are aluminum with a factory finish, but the area where both panels meet traps moisture after our afternoon downpours. Once the finish wears inside that channel, you get white oxidation and a door that binds. We clean, treat, and often swap in a weep-modified interlock so standing water exits instead of sitting.
• Targa and 6000 series track clogging from sand and debris. Miami Springs yards run sandy, and tracked sliders in the 6000 line collect grit where the rollers ride. The door gets progressively harder to move until someone yanks it and bends the track. We flush the track, true the rail, and adjust roller height before recommending any track replacement.
• Warped screens on CGI patio doors from afternoon sun exposure. The factory screen frames on several CGI lines are thinner aluminum and will bow under direct western exposure, which half the patios in this neighborhood get. A bowed screen is not a big repair, but if ignored it scrapes the door frame and wears the finish. We re-frame with a stiffer extrusion and re-screen on site.
• Failed weatherstripping along the header on older CGI installs. Original foam weatherstrip on early-2000s CGI sliders turns to dust after a decade of UV and rain. You get daylight through the top of the door and a not-so-small gap for air and water. We strip and replace with a denser EPDM profile that fits the original kerf so the door stays within its air and water ratings.

Our CGI Sliding Glass & Patio Doors Process

Here’s how a CGI job goes when you call Winslow:

1. 1
   You describe what’s happening. A live person answers, not a voicemail loop. Ed or one of our senior techs will ask about the door’s age, the series if you know it, and exactly what it’s doing.
2. 2
   We come out and diagnose. Every tech arrives in uniform, background-checked, and ready to pull the door apart enough to see the real problem. We don’t guess from the driveway.
3. 3
   You get a written price before we start. Line items for parts and labor. If the fix is simpler than we thought, the price goes down, never up.
4. 4
   Parts go OEM where it matters. For rollers, locks, and interlock hardware on newer CGI doors, we use genuine CGI parts. For wear-and-tear items like weatherstrip and screen material, we use quality aftermarket that matches or beats factory specs.
5. 5
   We test the door like the inspector would. Cycle it, check the lock, run water on the exterior, and confirm the interlock seals. Then we clean up and walk you through what we did.
6. 6
   The Done Right Promise backs the work. If something we fixed isn’t right, we come back and make it right.

What CGI Sliding Glass & Patio Doors Costs in Miami Springs

Straight numbers, because that’s how we quote. Here’s what CGI slider work typically runs in Miami Springs:

• Roller replacement, parts and labor: $180-$340 per panel, depending on series and whether the track needs dressing
• Interlock repair or replacement on the meeting rail: $220-$450, including treatment and weep modification
• Weatherstripping replacement, full door perimeter: $140-$280

• Full CGI slider replacement, installed: $3,800-$8,500, driven by opening size, glass package, and whether you’re moving to an impact-rated unit
