Get your free estimateCGI Window Installation: The Jacksonville Owner’s Guide
CGI window installation in Jacksonville typically runs between $140 and $320 per window for a full-frame replacement depending on size, glass package, and whether the existing frame needs remediation. We carry CGI-compatible hardware, balances, weatherstripping, and glass packages on our trucks, and most single-window swaps are completed the same day we arrive. Owners usually discover a part has failed after a storm, when a window that once sealed tight starts letting in the muggy Florida air, or when a crank handle snaps mid-turn. This page covers exactly what to check, what replacement costs look like, and when the smarter move is a professional install rather than a weekend fix.
At Lightwell Windows Jacksonville, we work with CGI products regularly. We’re an independent service provider, not affiliated with CGI, which means we recommend the right fix for your specific model without being tied to one vendor’s playbook. Keith Yamada and our crew have handled CGI replacements from the historic bungalows in Riverside to newer builds off Hodges Boulevard, and the salt air near San Pablo Road gives us a front-row seat to which components wear first.

Which CGI Models This Applies To
CGI’s window lines are built around impact-rated aluminum frames, and the model number on your window is the fastest way to confirm compatibility. Look for the silver sticker on the inside track of the sash or on the header above the glass. CGI’s Estate Collection, Sentry, and Targa series all use different hardware sets, so matching the part to the series matters more than matching it to the rough opening size.
The gotcha we see often in Jacksonville: a homeowner measures the visible glass and orders a sash or balance based on that dimension alone. CGI sashes are sized by the frame’s overall height and width, not the glass. A quarter-inch difference changes which balance cartridge fits, and forcing the wrong one strips the track. If you can’t find the sticker, measure the full frame outside edge to outside edge and give us that number over the phone. We’ll match it against CGI’s spec sheets before any part gets ordered.
When it comes to OEM versus aftermarket, the honest answer is that both can work. CGI’s OEM weatherstripping and balance cartridges are engineered for their exact extrusion profiles, and that’s what we install when the window is under warranty or when the owner wants a factory match. But a quality aftermarket balance from a manufacturer like Amesbury or a marine-grade weatherstrip can sometimes outlast the original in coastal Florida, because the material is rated for higher humidity and salt exposure. We’ll walk you through the price difference and let you decide before we order anything.

Signs Your CGI Window Installation Is Failing
- The sash drops when you release it. This is almost always a failed balance cartridge. CGI uses a spring-and-drum balance system, and when the spring fatigues, the window won’t stay open. You’ll feel it first as a heavier-than-normal lift, then a slow drift downward.
- You feel a draft or see condensation between the panes. Condensation inside the glass means the seal has failed and the argon or krypton gas has escaped. In Jacksonville’s humidity, a failed seal also invites mildew along the sash edge if it’s left alone too long.
- The crank handle spins without moving the sash. That’s a stripped gear in the casement operator. CGI’s heavy impact-rated sashes put real torque on the operator mechanism, and after five to seven years of daily use in humid air, the internal gears can wear smooth.
- The window is hard to lock or the lock won’t engage. Salt air in neighborhoods like San Marco and Ortega causes aluminum lock hardware to corrode subtly. The corrosion may not be visible, but it changes the alignment just enough that the keeper no longer seats properly.
- You hear rattling during high wind or when someone walks past. Loose weatherstripping or worn corner keys let the sash move inside the frame. This is the cheapest fix on this list, but ignoring it accelerates wear on the balances and the lock set.
Replacement Cost & What’s Included
For Jacksonville homeowners, here’s what we quote on CGI work, and what each line item covers:
| Service | Typical Price Range | What’s Included |
|---|---|---|
| Balance cartridge replacement | $90 – $180 per window | New spring-and-drum cartridge, sash realignment, lubrication |
| Weatherstripping replacement | $70 – $150 per window | Full perimeter seal replacement, sash adjustment, lock alignment |
| Casement operator replacement | $110 – $230 per window | New operator gear set, crank handle, track lubrication |
| Full-frame CGI window installation | $140 – $320 per window | New sash, frame remediation if needed, trim, cleanup, haul-away |
The range within each line item comes down to window size and whether we’re working on a first-floor single-hung in a new home off Gate Parkway or a second-story casement in a 1950s Avondale bungalow with framing that needs shimming. You get a written price before any work starts, and that price is the price. If we find hidden damage once the sash is out, we stop, show you what we found, and re-quote before touching anything else. The 365-Day Done Right Promise covers the work: if something isn’t right, we make it right, no debate.

Some things on this list are safe to check on your own. If your window is sticking or rattling, you can inspect the weatherstripping for visible cracks, clean the track with a dry cloth, and confirm whether the lock aligns when closed. Those checks cost you nothing and help us give a more accurate phone quote.
What we don’t recommend doing yourself is anything involving the balance system. CGI impact-rated sashes are heavy, and the spring tension inside a balance cartridge stores enough energy to break a finger or a window if it releases incorrectly. If the sash is dropping, call us. The same goes for casement operator gears, which are under constant tension when the window is closed. It’s a quick swap for our crew, but the wrong move with the wrong tool turns a $150 job into a much bigger one. Call (904) 914-3691 and we’ll schedule a look.
FAQs
In coastal Jacksonville, we typically see balance cartridges last six to nine years and weatherstripping last four to six years before the salt air and humidity take a real toll. Homes within a mile of the St. Johns River or the Intracoastal tend to be on the shorter end of that range, while inland neighborhoods like Mandarin or Baymeadows often get an extra year or two. If your CGI windows are approaching seven years old and you’re noticing stiffness or drafts, it’s worth having us inspect them before a failure becomes obvious in the middle of August. Call (904) 914-3691 for an exact quote; estimates are free.
In some cases, yes, especially with weatherstripping that has simply shifted out of its channel or a lock keeper that needs realignment rather than replacement. But balance cartridges and casement operator gears are sealed units; once they fail, the honest fix is a new part. We never patch something that will fail again in six months when a replacement costs about the same. If you’re not sure whether your issue is repairable, call (904) 914-3691 and describe what the window is doing; we’ll tell you over the phone what’s likely and what it costs.
Most single-part replacements, like a balance cartridge or weatherstripping set, take between one and two hours from the time we arrive to the time we’re vacuuming the sill and putting the drop cloths back in the truck. A full-frame window installation runs three to four hours for a standard-sized opening. We’ll give you a time window when you book, and we’ll call or text when we’re on the way, so you’re not parked at home waiting on a guestimation.
We stock the most common CGI balance cartridges, weatherstripping profiles, casement operators, and lock sets on our trucks. For less common sizes or special-order glass packages, we can usually source the part within three to five business days. If we have to order, we’ll tell you the exact timeline before you agree to anything, and we won’t take the old window out until the new part is in hand. Call (904) 914-3691 with your window model or frame measurements and we’ll check stock while you’re on the phone.
