CGI Window Installation: The Lighthouse Point Owner’s Guide
CGI window installation in Lighthouse Point typically runs $340-$780 per opening for standard vinyl or aluminum replacements, with impact-rated units starting around $620 and custom geometric work reaching $1,400+. We stock CGI frame components, sash hardware, and glazing beads on our Lighthouse Point trucks, and most standard replacements are surveyed and installed within a single visit once the written quote is accepted. Homeowners usually discover a problem when the sash won’t stay open, they feel air moving at the meeting rail, or they spot corrosion blooming at the weep holes after a humid summer.
Which CGI Models This Applies To
CGI manufactures across several series, and the part you need depends on which line is in your wall. The Estate Series uses a heavier extrusion with a 3-inch frame depth and integrated reinforcement channel, while the Sentinel Series runs a slimmer 2.5-inch profile designed for impact compliance without the bulk. The Targa Series, common in Lighthouse Point canal homes from 2016-2022, uses a proprietary glazing bead that looks standard but measures 0.562 inches wide, not the 0.500 found on PGT and CWS equivalents.
To identify your series, check the etched code in the glass corner or the label on the frame head. The first three letters after “CGI” tell us the extrusion generation. We carry OEM CGI hardware and select aftermarket equivalents rated for the same DP (design pressure) ratings. For Targa and Estate jobs, we default to OEM on moving parts; for fixed picture windows, a tested aftermarket keeper or glazing bead from our verified suppliers performs identically at lower cost. We document which route we propose and why in your written scope.
Signs Your CGI Window Installation Is Failing

- The sash drifts or won’t hold position. This usually means the balance system has lost tension or the pivot bar has worn where it engages the shoe. In Lighthouse Point, we see this accelerated by salt air corrosion at the balance housing, especially on east-facing windows within a quarter mile of the Intracoastal.
- Visible moisture between glass panes. The insulating glass unit (IGU) seal has failed, and the desiccant is saturated. Once you see fogging, the low-E coating is already degrading at the edge; the fix is a full IGU replacement, not a wipe-down.
- Air infiltration at the meeting rail or sill. The weatherstrip has compressed past recovery or the sill track has worn a channel. On older CGI units, the pile weatherstrip was bonded with an adhesive that stiffens after seven to ten years of Florida UV exposure.
- Frame corrosion or pitting at the weep holes. Aluminum frames in Lighthouse Point collect salt residue that doesn’t fully flush during our brief winter rains. Weep holes clog, water ponds, and the finish breaks down at the lowest point of the frame.
- Hardware operates roughly or the lock won’t engage. The keeper has shifted, the cam is worn, or the multipoint has thrown out of sequence. Forced closure bends the linkage; continued use risks frame damage that turns a hardware swap into a full sash replacement.

AfterReplacement Cost & What’s Included
| Service | Price Range in Lighthouse Point |
|---|---|
| Standard sash balance / pivot bar replacement | $180-$290 |
| IGU replacement (double-pane, standard size) | $340-$520 |
| Full sash replacement (operable, non-impact) | $420-$680 |
| Impact-rated sash or frame section replacement | $620-$940 |
| Custom geometric or architectural unit | $890-$1,400+ |
These are installed prices: part, labor, disposal, and documentation. What moves a job to the higher end is frame damage requiring structural repair, impact-rated glass with laminated interlayers, or access constraints on second-story canal homes where we rig from the water side. Every quote is line-itemed; the price we write is the price on the invoice. No change orders, no “while we’re here” additions. The 365-Day Done Right Promise covers the installation and the part.
DIY or Call Us?

There is no dangerous spring or electrical hazard in standard window hardware replacement, but there is a precision hazard. A sash removed without proper support drops hard and fast. A balance installed with the wrong tension walks the sash up or lets it crash down. A glazing bead seated with a metal tool instead of a polymer wedge chips the glass edge, and that chip becomes a crack in the first cold snap.
What you can safely check: confirm the series from the frame label, photograph the failure, and verify whether the window is still under CGI’s original warranty (typically ten years on non-impact vinyl, twenty on aluminum). What we handle: measuring the exact balance length and weight code, sourcing the correct glazing bead profile, and installing with the torque settings CGI specifies for its fasteners. Measure twice, write it down, then we talk price. Call (754) 600-8907 to schedule your free estimate.
FAQs
Aluminum units typically perform 20-25 years in South Florida’s coastal environment; vinyl ranges 15-20 years before major component replacement. Salt exposure within a half mile of open water accelerates hardware corrosion by roughly 30 percent. Call (754) 600-8907 for an exact quote on your specific unit - estimates are free.
Hardware and weatherstrip can sometimes be adjusted or re-secured, but failed IGUs and worn balances require full replacement; there is no field repair that restores factory performance. We note in your written scope whether adjustment or replacement is the honest recommendation. Call (754) 600-8907 for an exact quote - estimates are free.
Most standard hardware replacements take 45-90 minutes per opening; IGU replacements run 2-3 hours including cure time for the sealant. We stock common CGI balances, keepers, and glazing beads on our Lighthouse Point trucks, so the job is typically completed in one visit after the measured survey. Call (754) 600-8907 to schedule.
We stock the most common CGI hardware and glazing components for Estate, Sentinel, and Targa series on our Lighthouse Point trucks. Specialty or discontinued parts order within 5-7 business days, and we schedule installation only after confirming the part is in hand. Call (754) 600-8907 to verify availability for your model.
