CGI Windows & Doors: The Jacksonville Owner’s Guide
If you own a home in Jacksonville with CGI windows or doors, you own some of the most heavily engineered impact-rated openings made for coastal Florida. A failed part means your protection is compromised, and that part needs to be matched to your specific CGI series, not guessed at. We stock common CGI-compatible hardware and weatherstripping on our trucks and can source the rest directly, with parts-only swaps typically running $150 to $650 and full window replacements from $4,500 to $25,000 depending on size, series, and install complexity. Most owners discover a failing part the day a window won’t latch, a door sticks against the jamb, or water shows up on the sill after a hard Jacksonville storm.
Elmstead Remodeling Jacksonville is an independent service provider. We are not affiliated with CGI, but we work on their products regularly across Jacksonville, from Avondale bungalows to new construction in Nocatee, and we know which parts fail first in this climate and which ones are worth replacing versus repairing.
Which CGI Models This Applies To

CGI’s product line is built around a few distinct families, and the part that fits one will not always fit another. The most common lines we service in Jacksonville are the Sentinel series (aluminum frame, mid-range impact rating), the Tribute series (vinyl, popular in newer suburban builds), and the Estate Collection doors, which use heavier gauge hardware than the window lines. If you still have the original paperwork, the series name and model number are on the top line of the spec sheet. If not, open the sash and look for a laser-etched or printed label along the interior edge of the frame, usually on the hinge side for casements and the head jamb for sliders.
When we replace a part on a CGI product, we match it to the series and the year. CGI changed their roller assembly spec on sliding doors around 2014, and we have seen homeowners buy the older roller kit only to find the wheel diameter is off by an eighth of an inch, which makes the door drag no matter how clean the track is. For hardware like latches and keepers, original CGI components are worth the extra cost because the locking geometry is engineered to the frame. For consumables like weatherstripping and sweep seals, we often recommend a quality aftermarket equivalent that meets or exceeds the original spec at a lower price.

Signs Your CGI Windows & Doors Is Failing
Most CGI failures announce themselves slowly. Here is what we see most often in Jacksonville homes, and what each symptom actually means:
- The sash won’t stay locked. The keeper plate has worn or the latch has slipped out of alignment. On CGI single-hung units, the tilt latch spring is the usual culprit, and it is a small part with a big security job.
- Water on the interior sill after rain. In most cases this is failed weatherstripping or a clogged weep hole, not frame damage. Jacksonville’s summer downpours will find any gap, and CGI’s weeps need to be clear to drain properly. If the water appears only during wind-driven rain, check the corner seals.
- The door drags or stutters on the track. This is almost always a worn roller assembly. East coast salt air and fine sand work into the bearings and the nylon wheels flat-spot. A patio door should glide, not grind.
- Visible corrosion or white powder on aluminum parts. Jacksonville is a corrosive environment. CGI anodized finishes hold up well, but hardware placed near the coast, especially in Atlantic Beach or Ponte Vedra, will eventually show pitting. The white residue on bare aluminum is oxidation and it is a sign the finish has failed.
- Fog between the glass panes. The insulating glass unit seal has failed, and the fix is IG replacement, not a hardware swap. On impact-rated CGI glass, this means ordering a new laminated unit matched to your frame size and series.

AfterReplacement Cost & What’s Included

Hardware repairs on CGI windows and doors in Jacksonville generally fall in the $150 to $650 range when we are swapping a roller, latch, keeper, or weatherstripping kit. A full window replacement runs $4,500 to $15,000 for standard sizes, and impact window installation across a larger opening or in a hard-to-reach second-story location can push into the $8,000 to $25,000 territory, which matches what we quote across Jacksonville for new CGI and CGI-equivalent installs.
The price you get from us before any work starts is the price you pay. We write the material cost by part number, list the labor by stage, and do not use allowance line items. If a silicone seal or a frame screw is needed, it is on the estimate, not added after the fact. Every part we install carries our workmanship warranty, and all work falls under the 365-Day Done Right Promise: if it is not done right, we make it right.
DIY or Call Us?
You can safely check the weep holes, clean the track, and apply a silicone lubricant to the roller channel. Those are maintenance tasks. Replacing a roller assembly on a CGI patio door is another matter. The door panel is heavy, often 150 pounds or more for an impact-rated unit, and the springs that hold the panel in the frame are under constant tension. One slip here and you are looking at broken glass, a twisted frame, or worse. The same applies to spring-loaded window balances on the Sentinel and Tribute lines. If the part that failed is a latch or a keeper, that is a straightforward swap most owners can handle. If it involves lifting a panel or releasing tension, call us at (904) 643-6243 and let a technician who has done it in Jacksonville’s salt-air conditions many times handle it.
FAQs

CGI’s aluminum-framed lines, like the Sentinel series, can last 30 years or more with proper maintenance, but the hardware, rollers, latches, and weatherstripping has a realistic lifespan of 7 to 12 years in Jacksonville’s humidity and salt air before something needs replacing. Vinyl frames trend slightly lower, around 20 to 25 years, because the material fatigues differently under constant UV.
Some can, some cannot. A worn sweep seal or weatherstripping is a straight replacement. A corroded roller assembly is replaced, not rebuilt, because the bearing is sealed and the wheel is done. We will tell you which one you have and quote the fix honestly. Call (904) 643-6243 and we will walk through it.
Most single-part replacements on CGI windows take 30 to 60 minutes. Patio door roller replacement can take 90 minutes to two hours because the panel comes out, the old rollers come off, and the panel goes back in and gets realigned. We tell you the window of time before we arrive, and we work quiet when children are napping.
We stock common replacement parts on our trucks, including rollers, latches, keepers, and several weatherstripping profiles that fit CGI series. Uncommon sizes or series-specific hardware gets ordered direct, and we give you a clear arrival date before any work begins. We also stock parts for KraftMaid cabinetry, Cambria and Silestone countertop fittings, and other brands we service across Jacksonville.
If you have a CGI window or door that is sticking, leaking, or not locking, call us at (904) 643-6243. We will name the part, name the price, and set a day for the fix. Name the material, name the day, name the price, then there is nothing left to wonder about.
