CGI Door Installation: The Miami Lakes Owner’s Guide
CGI door installation in Miami Lakes typically runs $1,800-$4,200 for a standard replacement depending on series, impact rating, and whether the frame needs reconfiguration. We stock CGI hardware, sills, and jamb components for same-day installation on most residential series, and we carry PGT and CWS equivalents when a cross-reference makes sense. Most Miami Lakes owners discover their CGI door is failing when the sweep gap widens enough to let water pool during summer storms, or when the multi-point lock no longer draws the slab tight against the jamb.
Which CGI Models This Applies To
CGI manufactures several door series that circulate through Miami Lakes homes, and the part you need depends on which line was originally installed. The Estate Collection uses a heavier 2-1/4-inch slab with proprietary mortise hardware that does not interchange with the Sentinel or WinGuard residential lines. WinGuard aluminum doors carry the impact-rated label and use a reinforced jamb with a deeper rabbet, 1-3/8 inches versus 1 inch on the non-impact Estate equivalent. Check the hinge stile for a stamped series mark, or the glazing label in the corner of the glass.
We source OEM CGI hardware through the manufacturer’s Florida distribution network, though we also stock quality aftermarket multi-point mechanisms and adjustable sills that meet the original spec. The aftermarket route saves roughly 15-20 percent on parts cost, but we only recommend it when the exact OEM component is on backorder or when the original design has a known wear pattern. For WinGuard impact doors, we stay with OEM latches and deadbolts; the Miami-Dade HVHZ approval chain matters if you ever need a re-inspection letter.
Signs Your CGI Door Installation Is Failing

- Visible daylight under the slab when closed. The adjustable sill cap has compressed or the sweep has hardened in the Florida sun. On east-facing doors in Miami Lakes, we see this after six to eight years of morning UV exposure.
- Multi-point lock handle spins without engaging the bolts. The gearbox inside the mortise mechanism has stripped, usually from forcing the handle when the door is swollen or misaligned. CGI’s older Estate gearboxes used a zinc alloy that fatigues faster than the current brass-content version.
- Water intrusion at the threshold during heavy rain. The sill pan is either cracked, improperly flashed, or the end dams have separated from the jamb. Miami Lakes sits at roughly 8 feet above sea level with a high water table; hydrostatic pressure against the slab accelerates this.
- Door sticks or rubs at the top corner opposite the hinges. The frame has settled or the hinge screws have backed out of the stud. CGI’s aluminum frame is rigid, so the building moves around it.
- Condensation between glass panes. The insulating glass unit seal has failed. On south and west exposures in Miami Lakes, thermal cycling breaks the butyl seal faster; we replace the IGU, not the whole door, when the frame and hardware are sound.

The spread reflects three variables: whether the existing frame is square and plumb, whether the rough opening needs structural repair, and whether the original installation included a proper sill pan with end dams. Our measured survey determines which applies before we quote. The written price you receive is the invoice price; Haven Clause 1 governs every job. Parts carry the manufacturer’s warranty, and our labor is covered by the 365-Day Done Right Promise stamped under the Haven Standard.
DIY or Call Us?

An owner can safely inspect the sill cap adjustment screws and confirm whether the sweep is intact, but we do not recommend removing a CGI multi-point lock mechanism or adjusting hinge positions yourself. The Estate and WinGuard series use spring-loaded deadbolts under significant compression; improper handling can launch components or pinch fingers. More importantly, a misaligned slab compromises the impact rating and voids the Miami-Dade product approval if the hardware is not reinstalled to factory torque.
We carry CGI-specific shims, sill pans, and fasteners on every truck serving Miami Lakes. If you have the series name and approximate door size, call (786) 755-8730 and we will confirm stock before scheduling. The measured survey is free, and you keep the document.
FAQs
Twelve to eighteen years for the slab and frame, six to ten for the multi-point hardware, assuming direct sun exposure and normal use. East-facing doors tend to need sill and sweep attention sooner due to morning UV and salt air drift from the Atlantic. Call (786) 755-8730 for an exact assessment of your installation.
Often, yes. A stripped gearbox, cracked sill cap, or failed IGU can be component-replaced without touching the frame. We only recommend full replacement when the frame is out of square by more than 1/4 inch, the jamb is rotted or corroded, or the slab itself is delaminated. Call (786) 755-8730 for a free second opinion on any written estimate.
A standard slab swap in an existing, square frame takes three to four hours. If the rough opening needs reframing or the sill pan must be rebuilt, plan on a full day. We test every operating component with the homeowner before leaving; Sonia’s standing rule is that she does not leave until the hardware has been tested by someone other than her.
We stock multi-point mechanisms, adjustable sills, sweep kits, and common IGU sizes for CGI’s residential series. Specialty hardware for older Estate configurations or custom sizes typically requires a next-day pull from distribution. We confirm parts availability when you call (786) 755-8730 so we do not waste your time with a second trip.
Sightline Windows & Doors Miami Lakes is an independent service provider and is not affiliated with CGI. We also stock and install PGT, CWS, and ES Windows door systems when the opening calls for a different performance tier or price point.
Call (786) 755-8730 to schedule your free measured survey. We will read the rough opening before we quote it, not after. Measure it right the first time or budget for the second trip.
