CGI Sliding & Patio Doors: The Boynton Beach Owner’s Guide
We stock and install CGI-compatible sliding and patio door systems in Boynton Beach, with typical installed replacement costs running $1,800-$4,200 depending on panel size, impact rating, and frame material. Most CGI sliding door hardware and roller assemblies are on our trucks, and full panel replacements ordered from CGI’s Opa-locka facility typically arrive within 5-7 business days. Homeowners usually discover a problem when the door sticks during afternoon humidity, the rollers grind across the track, or the locking mechanism won’t engage after a storm season.
Which CGI Models This Applies To
CGI builds sliding and patio doors across several series, and the parts are not interchangeable between lines. The Estate Series uses a heavier-duty stainless steel roller carriage rated for panels up to 150 lbs, while the Sentinel Series and Targa Series share a common roller size but different track profiles. The Estate 7000 and Estate 8000 sliding doors use a distinct two-point mortise lock that differs from the single-point latch on the Impact Resistant line.
To identify your exact model, check the etched marking on the glass spacer bar or the interior frame sticker near the top jamb. We need the series name, approximate panel dimensions (width x height to the nearest quarter-inch), and whether the door is impact-rated or non-impact. CGI’s impact-rated units carry a Florida Product Approval number that begins with FL followed by digits; non-impact units lack this marking.
We are an independent service provider, not affiliated with CGI. For hardware-only repairs, we stock quality aftermarket rollers, tracks, and locks that meet or exceed OEM specifications at lower cost. For full panel replacement, we order factory-direct to maintain warranty coverage and exact color matching. Sonia Raman checks every CGI order against the original specification sheet before it ships; mismatched frame depths are the most common ordering error she has seen in twenty years of field work.
Signs Your CGI Sliding or Patio Door Is Failing

- The door requires shoulder pressure to move. This usually means the roller assembly has flattened or corroded. In Boynton Beach, salt air accelerates bearing wear, and we regularly find rollers seized after 4-6 years on homes near the Intracoastal, even on stainless steel hardware.
- Grinding or popping sounds from the bottom track. The roller wheels may be cracked, or debris has worn grooves into the aluminum track itself. Once the track is scored, new rollers will fail prematurely unless the track is replaced or resurfaced.
- Visible daylight or water intrusion at the sill after rain. The door sweep or interlock weatherstrip has compressed beyond recovery. CGI uses a specific pile height and backing width; generic replacements rarely seal correctly and can void the door’s impact rating if they interfere with panel engagement.
- Lock handle turns but the bolt doesn’t throw fully. The mortise lock mechanism has worn internal cams, or the frame has settled and the strike plate no longer aligns. Forcing the handle will snap the internal linkage, turning a $180 lock replacement into a $400+ panel disassembly.
- Condensation between glass panes. The insulating glass unit (IGU) has lost its seal. CGI’s standard IGU warranty is 10 years from manufacture date, but the installation date and proper documentation determine whether the claim is valid. We photograph the etch code and document the failure for every IGU we replace.

AfterReplacement Cost & What’s Included
| Component | Typical Range (Installed) |
|---|---|
| Roller assembly replacement (pair) | $280-$420 |
| Track repair or replacement | $340-$580 |
| Mortise lock / handle set | $180-$320 |
| Weatherstrip / sweep replacement | $140-$240 |
| IGU replacement (per panel) | $380-$620 |
| Full panel replacement (impact-rated) | $1,800-$3,400 |
| Full panel replacement (non-impact) | $1,200-$2,400 |
| Complete door system (dual-panel, impact) | $2,800-$4,200 |
What drives the range: panel size (CGI makes up to 12-foot-wide multi-slide configurations), impact versus non-impact glass, frame finish (standard white, bronze, or custom color), and whether the existing frame pocket is square and plumb. A frame out of true by more than 3/16 inch requires reframing, which we quote separately before any work begins.
Every repair includes our measured survey, written scope with line-item pricing, installation, operational testing, and the documented photo record you keep. The 365-Day Done Right Promise covers all labor; manufacturer parts carry their original warranty. Haven Clause 1 means the price on the page is the price on the invoice.
DIY or Call Us?

There are two things a homeowner can safely check without tools: whether debris is blocking the track (vacuum it out), and whether the lock strike plate has visible loose screws (tighten with a Phillips head). Everything else carries risk.
CGI sliding door panels weigh 80-150 pounds depending on size and glass type. Removing a panel to access rollers requires lifting it clear of the track while maintaining alignment; a dropped panel shatters tempered glass and can sever fingers. The mortise lock mechanism contains spring-loaded components under tension. We have replaced doors where a homeowner’s DIY roller purchase was the wrong axle diameter, causing the panel to ride cockeyed and destroy the track within weeks.
Our crew carries the correct roller sizes, track gauges, and lock configurations for every CGI series on the truck. Call (561) 421-3844 to schedule your free estimate. We will measure, identify the exact part, and give you the written price before any work starts.
FAQs
Quality rollers last 6-10 years in coastal Boynton Beach conditions, but homes within a mile of the Intracoastal or ocean typically see 4-6 years due to salt air corrosion. We use stainless steel or polymer-coated rollers rated for marine environments when we replace them. Call (561) 421-3844 for an exact quote on your model - estimates are free.
Hardware failures - rollers, locks, tracks, weatherstrip - are almost always repairable. IGU seal failure and frame rot require panel replacement. We diagnose on site and tell you which category you’re in before quoting. Call (561) 421-3844 for an exact quote - estimates are free.
A hardware repair (rollers, lock, track) takes 2-3 hours. A full panel replacement takes one day for standard sizes, two days for oversized or multi-slide configurations that require reframing. We do not promise same-day completion on full replacements; the Haven Standard requires the opening be measured, ordered, and installed with documented checks at each stage. Call (561) 421-3844 to schedule.
We stock rollers, tracks, locks, and weatherstrip for all common CGI series. Full panels and custom-color frames are ordered factory-direct with a 5-7 day lead time from CGI’s Opa-locka facility. We also stock compatible parts for PGT, CWS, and ES Windows if your home has mixed manufacturer lines. Call (561) 421-3844 to confirm availability for your specific model.
