CGI Window Replacement: The Hialeah Owner’s Guide
CGI window replacement in Hialeah typically runs $340 to $890 per opening for standard single-hung impact units, with most jobs scheduled within 48 hours of the measured survey. We stock common CGI sash, frame, and hardware assemblies for same-day resolution when the failure is isolated to a replaceable component. Most Hialeah owners discover the problem during the first cool snap of December or after a summer storm, when a window that held pressure for years suddenly won’t latch, seal, or slide.
Which CGI Models This Applies To
CGI’s product line breaks into three series that matter for part matching: the Sentinel line (single-hung and horizontal roller), the Estate Collection (casement and awning with multi-point hardware), and the Targa by CGI impact-rated line. The label you need is the etched mark in the glass corner or the stamped aluminum tag on the frame jamb, which carries the series code, glass thickness, and manufacturing date. We do not guess from photographs; we measure the rough opening, the sash dimension, and the glazing pocket depth before ordering.
OEM CGI parts ship from their Miami-Dade distribution point in two to five business days. For hardware failures on units older than twelve years, we often spec quality aftermarket equivalents from Truth Hardware or Caldwell, which match the original tolerances and carry the same finish warranty. The gotcha: CGI changed its roller housing design in 2019, and pre-2019 Targa horizontal rollers will not accept the current OEM track assembly without frame modification. We verify this on-site before quoting.

Signs Your CGI Window Replacement Is Failing

- The sash drops or won’t stay open. On CGI single-hung units, this usually means the balance shoe or spiral tensioner has slipped its track. Hialeah’s salt air corrodes the balance housing faster than inland climates; we replace the entire balance cartridge, not just the shoe, because the housing threads are already compromised.
- Visible moisture between the glass panes. The insulating glass unit (IGU) seal has failed. CGI units built before 2016 used a dual-seal polysulfide system that degrades faster in south Florida’s UV exposure. The fix is a full IGU replacement, not defogging; anything less and the desiccant is already saturated.
- Hardware operates but the sash won’t seal against the frame. The multi-point locking system may be intact while the keeper brackets have shifted. On Estate Collection casements, the brackets are aluminum and fatigue where they meet the frame; we measure the compression gap with a feeler gauge before ordering the corrected bracket set.
- Rolling sash grinds or jumps the track. The roller assembly has flat-spotted or the track itself has corroded. CGI horizontal rollers use a tandem roller design; when one wheel seizes, the other carries double load and fails within months. We replace both rollers and inspect the track for pitting that would destroy the new set.
- Frame corner shows separation or daylight. The mechanical splice in the aluminum frame has worked loose. This is structural; the thermal break and impact rating both depend on frame integrity. We assess whether a corner key repair suffices or the sash frame requires full replacement.

AfterReplacement Cost & What’s Included
| Component | Price Range (Installed) | Typical Lead Time |
|---|---|---|
| IGU replacement, standard size | $340 - $520 | 5 - 7 days |
| Balance / tensioner assembly | $280 - $410 | Same day (stocked) |
| Roller and track set, horizontal roller | $310 - $460 | 2 - 3 days |
| Multi-point lock hardware, Estate Collection | $380 - $580 | 2 - 5 days |
| Full sash replacement, impact-rated | $620 - $890 | 7 - 10 days |
The range reflects three variables: the age of the unit (older parts are harder to source), whether the failure damaged adjacent components, and whether the original installation left adequate clearance for removal without disturbing the exterior finish. Our quote is the measured survey converted to a written scope; the price on that document does not change once work starts. Every replacement carries the 365-Day Done Right Promise under Haven Clause 5: if the part fails or the seal does not hold, we return and correct it at no additional labor charge.
DIY or Call Us?

An owner can safely verify the model label, photograph the failure, and check for obvious obstructions in the track or weatherstrip. What we do not recommend: removing a sash from an impact-rated CGI unit without understanding the anti-lift hardware, or attempting to reglaze an IGU in place. The glazing stops on impact units are structural; reinstall them incorrectly and the unit no longer meets the Miami-Dade NOA it was built to. The glass itself is heavy, the edges are unforgiving, and a dropped sash in a second-story opening is not recoverable without help.
We carry common CGI hardware assemblies on our trucks for Hialeah calls. When the part is not in stock, we order it and schedule the return visit once it arrives, so the owner is not paying for two trips. Call (786) 574-2745 to schedule your free measured survey; we will name the price before any work starts, and the quote is yours to keep whether we do the job or not.
FAQs
CGI impact-rated units typically deliver 15 to 25 years of service in Hialeah, with hardware failures appearing around year 8 to 12 and IGU seal failures clustering in years 10 to 15. Salt exposure within two miles of the coast accelerates hardware corrosion by roughly 30 percent. Call (786) 574-2745 for an exact assessment of your unit’s condition; estimates are free.
Hardware can sometimes be adjusted or lubricated, but we do not repair failed IGUs, cracked frames, or worn balance assemblies; the fix is temporary and the callback costs more than doing it correctly the first time. Our written scope specifies replacement parts with traceable lot numbers. Call (786) 574-2745 to review what your unit needs; estimates are free.
A single component swap, balance or roller, takes 45 to 90 minutes on-site. Full sash or IGU replacement requires two to four hours, including removal, fit check, and seal verification. We do not rush the compression test; Haven Clause 4 requires documented evidence that the unit performs before we leave. Call (786) 574-2745 to schedule; estimates are free.
We stock balance assemblies, roller sets, and common hardware for CGI’s Sentinel and Targa lines on our Hialeah trucks. Estate Collection multi-point hardware and custom-size IGUs are ordered to specification after the measured survey. Call (786) 574-2745 to confirm availability for your model; estimates are free.
We also stock and install parts for PGT, CWS, and ES Windows units.
Measure it twice, name the price, skip the theater. That’s how we’ve handled every one of the 18,000+ openings since 2012, and it’s how we’ll handle yours.
