If your CGI sliding or patio door is dragging, jamming, or letting air through, we can match the exact part on-site and usually have the door sliding smoothly the same afternoon. Most hardware replacements and roller swaps in Fort Worth run between $180 and $420 installed, while a full door replacement typically falls between $1,900 and $4,600 depending on the glass package and size. The most common discovery is a door that worked fine in spring but suddenly needs a hip-check by fall, because the rollers have worn flat on one side after years of North Texas dirt working into the track.
Fort Worth’s fine caliche dust and summer heat do a number on nylon rollers and weatherstripping. We see it constantly: a door that slides like furniture across gravel, a latch that no longer lines up, a glass panel that fogs between the panes. The frustrating part for homeowners is that the difference between a $200 repair and a $600 repair is usually invisible until the door comes off the track. That is exactly why we price the work in writing before we start, and we show you the worn part before the new one goes in.
Which CGI Models This Applies To
CGI makes sliding and patio doors across a few distinct product lines, and the hardware is not universal between them. The Estate Collection and Targa series carry different roller assemblies and track profiles than the aluminum Sentry line, and mixing them causes the very binding and drag homeowners call us about. If you open the door and look at the frame edge, CGI stamps a model number and glass code on a small label near the bottom corner. That number is the fastest way for us to confirm the right part before we ever set foot in your home.
On the OEM versus aftermarket question, our honest take after years of installing both: CGI OEM rollers, locks, and keepers are worth the premium on doors that are ten years old or newer. The tolerances simply match better. On older doors where the track itself has worn, a quality aftermarket roller with a slightly taller wheel can buy you years of smooth operation at a lower price. We carry both and will tell you which one we would put in our own house. We are an independent installer, not affiliated with CGI, which means we recommend the part that fits your door and your budget, not the one a manufacturer wants us to move.
Styles & brands we work with










Signs Your CGI Sliding & Patio Doors Is Failing
- The door needs a shoulder to move. The rollers have flattened or the bearings are packed with dust and grit from Fort Worth’s dry, windy climate. You are not weak; your rollers are done.
- You can see daylight around the door edges. Weatherstripping has compressed or torn, which means your AC is cooling the back porch. This is a fast, inexpensive fix we handle regularly.
- The lock catches but does not hold. The keeper has shifted or the door has settled out of square. Do not live with a patio door that opens with a firm push even when locked; this is a safety issue we address immediately.
- Condensation between the panes. The insulated glass unit seal has failed. The glass cannot be “dried out”; the IGU gets replaced. On CGI doors this is usually covered under the glass warranty within the first ten years, and we can help you file that claim.
- The door jumps or grinds along the track. Either the track has debris ground into it or the bottom rail is sagging. Left alone, this destroys the new rollers you install, which is why we always inspect and clean the track as part of any roller job.

Keith Yamada is known for taking an extra twenty minutes on measurements rather than sending a crew back a second time. All work carries the 365-Day Done Right Promise: if something is not right, we make it right, no debate.
DIY or Call Us?
What you can safely do at home: vacuum the track, wipe down the frame, and note whether the door binds more in the morning or evening. That last detail helps us diagnose whether we are dealing with a roller failure or thermal movement in the frame. What you should not do is pull the door panels out yourself. Sliding glass panels run heavy, tempered glass handles poorly when the balance shifts, and a dropped panel costs more than the entire roller job. If the door is off-squaring or the lock no longer aligns, call us at (682) 900-6694 before the track gets damaged further.
FAQs
In our experience, the original rollers on a CGI door last 8 to 12 years in the Fort Worth area, with dust exposure and how often the door gets used being the two biggest factors. Homes near open fields or new construction tend to wear rollers faster because fine dirt works into the bearing grease. We recommend replacing rollers before they flatten completely; a door that grinds is already chewing up the track, and tracks are a much more expensive repair.
Yes, most of the time. Roughly 80% of the sliding and patio door issues we see in Fort Worth are repairable with new rollers, locks, or weatherstripping. A full replacement only makes sense when the frame itself is bent, the glass seal has failed and the warranty has lapsed, or the door no longer meets the homeowner’s energy expectations. We will show you the failed part and explain the repair before recommending anything more costly.
Most roller, lock, and weatherstripping jobs run 90 minutes to two and a half hours from the time our technician stages tools until the vacuum is back in the truck. We protect the floor with drop cloths, use shoe covers inside the home, and take a photo of the cleanup before we leave, per our C.A.R.E. values.
We carry CGI-compatible rollers, locks, keepers, and weatherstripping in common sizes on our service trucks, along with parts for PGT, CWS, and ES Windows doors. If your door needs a less common profile, we usually have it ordered and installed within a few business days. Call (682) 900-6694 with the model number from the frame label, and we will confirm availability before scheduling so you are not waiting on a second visit.
