CGI Window Replacement: The Davie Owner’s Guide

CGI window replacement in Davie typically runs $340 to $780 per opening for installed sash, frame, or hardware replacement, depending on whether you need a single component or a full-frame swap. We stock common CGI parts on our trucks and can usually source series-specific components within 24 to 48 hours. Most Davie homeowners discover a CGI window is failing when the sash won’t stay open, the lock won’t engage, or they feel air movement around the frame during a summer storm - signs that the balance system, interlock, or weatherstripping has reached end of life in South Florida’s salt air and UV exposure.

Which CGI Models This Applies To

CGI windows carry their series designation on a permanent label inside the frame jamb or top rail, usually a stamped metal tag or etched code. The most common lines we replace in Davie are the Estate Series (aluminum impact-rated), Sentinel Series (vinyl impact), and Targa Series (high-rise commercial aluminum). Each uses different sash balances, interlock profiles, and glazing bead dimensions.

The Estate Series 4500 and 4700 single-hung units, for instance, use a 5/8-inch interlock stack height that differs from PGT’s comparable WinGuard line by approximately 3/32 inch. That tolerance matters when retrofitting a sash into an existing frame. We verify with a digital caliper, not by eye.

CGI does not sell direct to homeowners; parts move through authorized distributors. We source OEM components through CGI’s Florida distribution network, though for certain discontinued series - the older Estate 2000 line, for example - we fabricate compatible interlocks and balances from aftermarket suppliers whose tolerances we’ve tested in the field. The decision between OEM and aftermarket depends on whether your series is current, whether the frame is square within 1/8 inch, and whether you need the replacement to match existing sightlines in a multi-opening wall.

Signs Your CGI Window Replacement Is Failing

• The sash drops or won’t stay open. This points to a failed coil balance or broken pivot bar in the jamb liner. In Davie’s humidity, the nylon bushings in CGI’s older coil systems crystallize after roughly 8 to 12 years, losing their grip on the balance shoe. The sash feels heavy and may slam shut unexpectedly.
• Visible daylight or air leakage at the meeting rail. The interlock gasket compresses permanently over time, especially on west-facing openings that take afternoon sun. Once the bulb seal loses its memory, no amount of latch pressure restores the barrier. We measure the gap with a feeler gauge; anything over 0.090 inch means replacement.
• Condensation between panes on insulated units. The edge seal has failed, allowing moist air into the airspace. In Davie, this accelerates when the desiccant in the spacer becomes saturated, typically after the unit’s 10-year insulating glass warranty expires. The glass pack must be replaced; defogging services do not restore the original U-factor or argon fill.
• Lock hardware operates but doesn’t draw the sash tight. The keep (strike plate) has wallowed out, or the cam has worn eccentric. CGI’s multi-point locks depend on precise engagement; a worn keep will not improve and will stress the lock mechanism until it too fails.
• Frame corrosion or pitting at the sill. Aluminum frames in Davie’s coastal environment develop galvanic corrosion where dissimilar metals contact, or where the anodized coating has been scratched during cleaning. Once pitting penetrates the substrate, the frame’s structural integrity and impact rating are compromised.

Replacement Cost & What’s Included

Our installed pricing for CGI window replacement in Davie follows the measured survey we leave with you. Typical ranges:

• Balance system replacement (single-hung): $340-$480
• Sash replacement (glass and frame, existing main frame retained): $520-$680
• Full-frame replacement (sash, frame, interior trim, exterior seal): $620-$780
• Insulated glass unit replacement (dual-pane, existing sash retained): $380-$540

These figures include the part, labor, disposal, and the documented photo record we provide on every job under the Haven Standard. What moves the price: whether the frame is square (out-of-square frames require custom shimming), whether we need to match anodized finishes that CGI has discontinued, and whether the opening requires impact-rated replacement per Davie’s Broward County HVHZ requirements. The written quote you receive before any work starts is the final invoice. No change orders, no surprises.

Every CGI replacement carries our 365-Day Done Right Promise. If the balance tension, lock engagement, or seal performance is not correct, we return and make it right.

DIY or Call Us?

An owner can safely inspect their CGI window for the symptoms above. Check the label for series and date code, operate the lock and feel for slop, and hold a lit candle near the meeting rail during a breezy day to detect air movement. Document what you find with photos; they help us confirm the part before we arrive.

What we do not recommend: removing a sash with a failed balance, extracting an insulated glass unit, or adjusting multi-point lock cams. CGI sashes in impact-rated series are heavy - 35 to 55 pounds for a typical 36-by-60-inch single-hung - and the coil balances store significant tension. A released balance can strike with force sufficient to damage the frame or cause injury. The glazing in impact units is laminated and thick; improper handling risks corner cracks that propagate under thermal stress.

We are an independent service provider, not affiliated with CGI. Our technicians carry the specific interlock gauges and balance tools for CGI’s series lines, and we stock common failure items on our trucks for Davie calls. If you have the model label and a description of the symptom, call (754) 254-8492 and we’ll confirm whether it’s a same-day fix or a sourced part with a firm date.

FAQs

How long should a CGI window part last in Davie?

In South Florida’s climate, expect 8 to 12 years from balance systems, 10 to 15 years from insulated glass edge seals, and 15 to 20 years from aluminum frames with proper maintenance. Salt air within five miles of the coast accelerates hardware corrosion by roughly 30 percent compared to inland Davie. Call (754) 254-8492 for an exact quote on your specific part - estimates are free.

Can the part be repaired instead of replaced?

Some components can be adjusted once: lock cams can be shimmed, and minor frame dents can be dressed. But coil balances, failed edge seals, and worn interlock gaskets are consumable items with no viable repair. We do not charge to inspect and will tell you honestly if a repair is possible. Call (754) 254-8492 for an exact quote - estimates are free.

How long does a CGI window replacement take?

A balance or lock replacement takes 45 to 90 minutes per opening. A sash swap takes 2 to 3 hours including seal inspection and operation testing. Full-frame replacement requires 4 to 6 hours per opening, plus any stucco or trim repair. We schedule by the job, not by the hour, and arrive with the part confirmed. Call (754) 254-8492 for an exact quote - estimates are free.

Do you stock CGI parts on your truck?

We carry balances, locks, keeps, and common interlock gaskets for Estate and Sentinel series on every Davie truck. Series-specific sashes and insulated glass units are ordered to measured dimensions after our survey; we do not guess on glass sizes. If your series is discontinued, we fabricate compatible components from tested aftermarket sources. Call (754) 254-8492 for an exact quote - estimates are free.

We also stock and install parts for PGT, CWS, and ES Windows lines.
