1. Choose your installer
The unit is half the job - the install is the other half. Our own background-checked crews measure, set, seal and insulate every opening, and they know the lines we quote inside and out because they install them every week.

Compare styles, materials and glass packages side by side until the fit is right for your rooms, your budget and your goals. The product-line comparison below is the place to start.
3. Prepare your home for install
Before install day we walk you through a short checklist - furniture pulled back, treatments down, a clear path to each opening - so install day is watch-it-happen, not scramble.

CGI Sliding & Patio Doors: The Olympia Heights Owner’s Guide
CGI sliding and patio door repair in Olympia Heights typically runs $340-$890 for track, roller, and handle hardware replacement, and $1,800-$4,200 for full panel replacement with impact-rated glass installed. We stock CGI-compatible rollers, tandem truck assemblies, and weatherstrip profiles on our trucks, and most hardware-only jobs in Olympia Heights finish same-day. Most owners realize something’s wrong when the door sticks during afternoon humidity or when the lock no longer seats flush after a storm season.
Which CGI Models This Applies To
CGI’s sliding and patio door lines divide into two frame platforms: the Estate Series (ES) with its 3-inch stile depth, and the Sentinel Series with the slimmer 2.5-inch profile used in many Olympia Heights townhome installs from 2016 to 2022. The roller trucks are not interchangeable between these series - the ES uses a 1.75-inch tandem truck with a stainless steel axle, while the Sentinel takes a 1.5-inch single truck with a nylon wheel that degrades faster in South Florida UV.
To identify your part, open the active panel and look for the CGI etched mark on the glass corner, then check the roller housing for a stamped part number (usually begins CG- or EST-). The interlock weatherstrip on pre-2019 Estate units uses a bulb-style seal; post-2019 units switched to a fin-seal design that compresses differently. We carry both OEM CGI hardware and quality aftermarket equivalents from Truth Hardware and Amesbury - the aftermarket rollers match spec at roughly 60% of OEM cost, though we recommend OEM interlock seals because the compression set tolerances are tighter.
Before
AfterSigns Your CGI Sliding & Patio Doors Is Failing
- The panel drags or requires shoulder force to move. This usually means the tandem truck rollers have flat-spotted or the axle has bent under repeated impact from frame settling. In Olympia Heights, we see this most often on doors facing west, where afternoon thermal expansion stresses the track geometry.
- Visible gap at the interlock when the door is “closed.” The interlock weatherstrip has compressed past its recovery point, or the keepers have shifted in their mortises. A 3/16-inch gap at center is enough to fail a wind-borne debris inspection and admit driving rain during a summer storm.
- Lock thumb-turn spins without engaging the deadbolt. The spindle has stripped or the mortise lock body has corroded internally. CGI uses a proprietary 45-degree spindle angle - standard 90-degree replacements will seat but not throw properly.
- Water pools on the interior track after moderate rain. Theweep holes are clogged with aluminum oxide or the sill dam has cracked. On ground-floor installs near Olympia Heights’ lower drainage areas, hydrostatic pressure can force water past an otherwise intact sill.
- Glass fogs between the panes. The insulating glass unit (IGU) seal has failed, allowing moist air into the airspace. This is not repairable - the IGU must be fabricated to the exact sightline dimensions and re-glazed into the sash.
Replacement Cost & What’s Included
| Component | Parts + Labor Range | Typical Timeline |
|---|---|---|
| Roller / truck assembly replacement (one panel) | $340-$520 | 2-3 hours |
| Full track and sill replacement | $680-$1,150 | Half day |
| Mortise lock and handle set | $290-$440 | 1.5-2 hours |
| IGU replacement (impact-rated, installed) | $890-$1,400 | 2-3 hours |
| Full panel replacement (Estate or Sentinel) | $1,800-$4,200 | Full day |
What drives the range: frame condition behind the trim, whether the rough opening has shifted, and whether the existing fasteners are stainless or have corroded into the substrate. Our written quote itemizes each line - Haven Clause 1 means the measured survey and the final invoice are the same document. Every hardware replacement carries our 365-Day Done Right Promise; full panel replacements include the documented photo record and the written warranty.
DIY or Call Us?
An owner can safely check three things: verify the weep holes are clear with a pipe cleaner, confirm the lock keepers are tight to the frame with a screwdriver, and measure the visible gap at the interlock with a feeler gauge. Do not attempt to remove the active panel solo - CGI’s Estate Series panels run 180-240 pounds, and the lift-and-swing maneuver risks back injury and frame damage if the panel torques during removal. The tandem truck assemblies sit under spring tension; releasing the adjustment screw without supporting the panel first drops the corner onto the track.

FAQs
Expect 7-12 years for nylon-wheel trucks and 12-18 years for stainless tandem trucks, though west-facing doors in Olympia Heights often see 20% shorter life due to thermal cycling. Salt air within three miles of the coast accelerates axle corrosion regardless of material. Call (786) 400-2761 for an exact quote - estimates are free.
Track dents and minor frame misalignment can be corrected; worn rollers, failed IGUs, and cracked sills cannot. We document what we find with photos and quote both repair and replacement options so you can decide. Call (786) 400-2761 for an exact quote - estimates are free.
Most CGI panel replacements finish in one day, assuming the rough opening is square within 1/4 inch and the exterior trim cooperates. We arrive with the measured survey already in hand - the document you approved is the scope we execute. Call (786) 400-2761 for an exact quote - estimates are free.
