Get your free estimateCGI Window Replacement: The Fresno Owner’s Guide
We replace and install CGI windows throughout Fresno, with most single-window replacements running between $600 and $1,400 installed depending on size, series, and glass package. We stock the most common CGI hardware on our trucks, which means many replacements happen the same day we arrive. Most Fresno homeowners call us after noticing a crank that spins without moving the sash, a latch that no longer seats, or condensation that has crept between the glass panes in an upstairs bedroom.
CGI builds a serious impact-rated window, but even the best hardware wears under Central Valley heat. When a part fails, you want it matched to your exact CGI series and installed so it seals the way the original did. Keith Yamada has spent more than two decades replacing windows across Fresno, and he will tell you the same thing he tells every homeowner: a window that fits right the first time does not ask for your attention again, and that is exactly the point.
Which CGI Models This Applies To
CGI windows are not one product line. The company builds across several series, and the replacement part that fits a CGI Estate window will not necessarily fit a CGI Classic or Targa model. Most CGI windows carry a label on the frame or sash with the series name and a manufacturing date code, and that label is the fastest way for us to pull the right part. If the label has faded under Fresno sun, we match by measuring the sash profile and hinge spacing, which we do on site before we quote anything.
On the OEM versus aftermarket question, our honest position is this: CGI hardware is well made, and for latches, keepers, and crank mechanisms we prefer the OEM part when it is available. For balance shoes, pivot bars, and weatherstripping, we have found high-quality aftermarket equivalents that match or beat the original spec at a lower price. We will tell you which we are quoting and why, so the decision is yours. One compatibility gotcha worth knowing: CGI tilt-latch spacing varies between vintages, even within the same series. A latch that is off by an eighth of an inch will look right until you close the window.
Styles & brands we work with










Signs Your CGI Window Replacement Is Failing
- Hard-to-turn crank or stripped crank mechanism: The gear teeth inside the operator wear down, especially on west-facing Fresno windows that take afternoon heat. You will feel the handle slip or grind before it stops working entirely.
- Sash drops or will not stay open: The balance system, usually a block-and-tackle or spiral balance on CGI models, loses tension over time. A sash you have to prop open with a book is a balance replacement waiting to happen.
- Water staining or fogging between panes: Condensation inside the glass means the inert gas fill has escaped and the seal has failed. This is a glass unit replacement, not a hardware fix, and it is common in windows older than 12 to 15 years in the Central Valley climate.
- Latch or keeper no longer lines up: Over years of settling and use, the sash shifts slightly and the locking points stop engaging. Sometimes a new keeper fixes it; sometimes the sash needs realignment at the hinges.
- Broken or bent hinge, especially on casement and awning windows: A hinge that sags under the weight of an impact-rated sash is nearing the end of its life. Continuing to operate it stresses the frame, which turns a hinge swap into a frame repair.
Replacement Cost & What’s Included
In Fresno, expect to pay between $175 and $450 for hardware-only replacement on a CGI window, parts and labor included, depending on the part and series. Full sash replacement runs higher, and a complete window replacement typically lands between $600 and $1,400 per opening. Everything we quote is a written, line-item price before any work starts, so there is no surprise at the end of the day.
Every replacement includes removal of the failed part, disposal, new hardware or glass matched to your CGI series, and a cleanup that leaves the room the way we found it. We put down drop cloths before we start, wear shoe covers, and take a photo of the finished cleanup before we leave. The work is covered by our 365-Day Done Right Promise, so if something is not right, we make it right with no debate.

Replacing a CGI window part is not a high-tension job like a garage door spring, but it is also not as forgiving as it looks. The parts that fail most often, cranks, latches, balances, and hinges, sit inside a precisely machined track, and forcing a part that is close but not exact can crack a sash or strip the frame. A stripped operator or broken balance also means the sash can be heavy and unpredictable, which is exactly when fingers get pinched.
What you can safely check yourself: the label on the frame or sash, whether the window still locks from both sides, and whether the problem is in the handle or the track. What you should call us for: anything involving glass, balances, or a sash that no longer moves smoothly. If you are not sure, call (559) 272-9650 and describe what the window is doing. We will tell you over the phone whether it sounds like a quick hardware fix or something that needs a site visit, and the estimate is free either way.
FAQs
Most CGI hardware lasts 15 to 25 years, but the Central Valley takes a toll on plastic and nylon components faster than coastal climates do. UV exposure and sustained heat over 100°F shorten the life of crank gears, tilt latches, and weatherstripping. If your windows are over 15 years old and you are replacing a second hardware component, it may be time to replace the window rather than keep chasing parts.
Sometimes. A stripped operator can occasionally have its gear replaced, and a misaligned latch can often be corrected with a new keeper. But many CGI components are designed as sealed units, meaning the fix is a new part rather than a rebuilt one. We will tell you which path makes sense for your specific window, because the right answer depends on the series and the part’s condition. Call (559) 272-9650 for an honest read, and the estimate is free.
Most hardware replacements, including cranks, latches, keepers, and balances, take 30 to 90 minutes per window once we are on site. Glass unit replacements usually take one to two hours. The longer variable is sourcing the correct part for your CGI series, which is why we stock the fast-moving items on our trucks and order the rest directly, usually with same-week arrival in Fresno.
We stock the most common CGI replacement hardware, including crank operators, latches, keepers, tilt pins, and balance systems for current and recent CGI series on our service trucks. Less common parts, including certain vintage tilt latches and custom glass packages, are ordered directly and typically arrive within days. We also carry a growing selection of PGT, CWS, and ES Windows hardware for customers who have mixed-brand homes.
