CGI Custom & Geometric Windows in Miami Shores: What to Know First

We provide independent CGI custom and geometric window repair, replacement, and installation in Miami Shores. Most custom CGI jobs take 2 to 4 weeks from template to finished install, depending on the shape and whether we’re working with tempered or laminated impact glass. Honest price posture: custom shapes cost more than stock rectangles, but we quote fixed prices with no change orders, so the number we give you is the number you pay.

This page is for Miami Shores homeowners who own CGI windows that are failing, want custom or geometric CGI windows installed, or need a straight answer about whether a shaped window can be saved. Call (727) 483-7883 and you’ll get a live person, not a voicemail.

How CGI Products Fail - and How We Fix Them

CGI builds some of the toughest impact windows in the industry, but Miami Shores heat, salt air, and storm cycles expose weak points that generic window companies miss. Here’s what we actually see on CGI jobs in this neighborhood:

  • CGI Estate Collection frame leaks at arched transom seams. The Estate series uses heavy extruded aluminum, and on radius and arch tops the sealant bead at the mull joint breaks down faster than on straight frames. Miami Shores gets afternoon downpours that drive water sideways, and a failed seam at the top of an arch lets water track down the interior drywall. We pull the arch trim, clean the original mull, re-bed with marine-grade sealant, and re-torque the mull screws to CGI spec.
  • CGI Sentinel series sash sag on oversized trapezoids. Big geometric openings with a triangular or trapezoid sash put uneven weight on the hinge side. After a few years of daily use, the sash drops a few millimeters and the locking cam misses the keeper. Owners think the lock is broken. It’s usually a hinge pack that’s worn on one side. We re-shim and replace the hinge set, which is a $180 to $320 fix instead of a $900 sash replacement.
  • Condensation between panes on CGI Targa series fixed geometric units. The Targa line was popular in Miami Shores for fixed shaped windows (half-rounds, pentagons, octagons). When the dual-seal spacer fails, humid Florida air gets pulled between the panes and you get fog you can’t wipe off. This is a sealed-unit failure, not a cleaning problem. We measure the opening, order a new insulated glass unit cut to the exact shape, and reset it with fresh setting blocks. It’s a same-structure repair that avoids tearing out the entire frame.
  • Roller and track wear on CGI Estate sliding geometric windows. Non-rectangular sliders are rare but they do exist in custom installations, and the geometry puts more stress on the rollers than a standard horizontal slider. We see flat-spotted rollers and aluminum track pitting, especially on west-facing walls that get the full afternoon sun in Miami Shores. We swap in stainless rollers and dress the track with a light file pass where needed. OEM CGI rollers are best here; aftermarket nylon rollers wear out in half the time.
  • Improper original flashing on second-story geometric installs. A lot of Miami Shores homes had CGI windows installed during the big hardening push after Wilma and Katrina. Some of those crews flashed shaped windows like they were rectangles, which doesn’t work on radius tops. Water pools at the apex of the arch and eventually rots the buck and the framing. We pull the unit, rebuild the rough opening, install a proper pan flashing with corners lapped, and re-set the window. This is a full re-install, not a patch job.

Our CGI Custom & Geometric Windows Process

Every CGI job we take in Miami Shores follows the same path. Nothing is left to guesswork.

  1. 1
    Call and diagnosis. You call (727) 483-7883, describe what you’re seeing, and we schedule a time to look. For custom shapes, we bring a laser template tool to capture exact radius and angle measurements, because a hand-drawn template on a complex arch is how expensive mistakes happen.
  2. 2
    Parts decision. We determine whether the window needs a CGI OEM part, a quality aftermarket equivalent, or a full replacement. For structural components like mullions, hinges, and rollers, we use CGI OEM parts when they’re available. For glass replacement on shaped units, we work with local Miami glass fabricators who cut to our templates.
  3. 3
    Fixed quote before work starts. You get a line-item price. If we find hidden damage once the window is open, we stop, call you, and agree on the change before proceeding. No surprises on the back end.
  4. 4
    The repair or install. Background-checked, uniformed techs do the work. Every shaped window gets set square, flashed properly, and sealed with tooled beads, not just caulk gunned into a gap.
  5. 5
    Water and air test. We run a spray-bar test on the exterior and check for any draft or leak path before we clean up. If it fails, we fix it before we leave.
  6. 6
    The Done Right Promise. If it fails due to our workmanship, we come back and make it right. That’s not a 30-day window or a “limited warranty.” Ed’s name is on it.

What CGI Custom & Geometric Windows Costs in Miami Shores

Custom and geometric CGI window work in Miami Shores runs higher than standard rectangular jobs because the glass is cut to shape, the framing is more complex, and installation time is longer. Based on the jobs we’ve completed in this area, here’s what owners can expect:

  • Repair a leaking arched CGI Estate transom: $220 to $480
  • Replace failed insulated glass in a fixed geometric Targa unit: $350 to $800 depending on shape and glass type
  • Re-hang a sagging oversized trapezoid sash with new hinges: $180 to $320
  • Full custom CGI impact geometric window, supplied and installed: $1,400 to $3,200 per unit depending on size, shape, and glass package
  • Remove and properly re-flash a second-story arch window: $600 to $1,100

What moves the price most is shape complexity, glass type (tempered vs. laminated impact), and whether wall repair is needed after a leak. We give free written estimates, no trip charge in our home county, and a 10% discount for seniors and veterans. Call (727) 483-7883 for an exact quote.

Reviews

What Neighbors Say About Winslow Windows & Doors

★★★★★

"Three big companies quoted us and every one sent a salesman with a leased truck. Ed turned up in a truck with his own name on the door, quoted less, and his crew were the same faces on day one and day nine."

YYolanda Betancourt
★★★★★

"A tile roof repair and new windows from the same company meant one crew, one permit runner, and nobody blaming the other trade. Ed checked the roof work himself before the tarp came off."

HHenrietta Pemberton
★★★★★

"Someone tried the back slider while we were away. The glass crazed and held, the alarm never had to earn its keep, and the police report reads better than it might have. Ed came out the next morning to check the frame himself."

CCornelius Adeyemi
★★★★★

"The old aluminium sliders howled every afternoon storm and swelter came straight through the glass. The new impact sliders shut with a sound like a bank vault and the back rooms finally hold their temperature."
