CGI Construction in Casselberry, FL | Sawyer Remodel Orlando
We provide independent CGI window, door, and siding service across Casselberry, from the Lake Kathryn basin up through Sausalito. The thing that makes our work different here comes down to this: we know how CGI’s impact-rated aluminum and vinyl lines actually fail in a high-water-table, high-humidity city, and we fix the root cause instead of just masking the symptom. Call (850) 809-0306 for a straight answer and a written price before any work starts.
We’ve been working on CGI products in Casselberry for over a decade. We’re not factory-authorized, and we won’t pretend to be. What we are is independent: that means we recommend the repair or replacement that makes sense for your house, not the one a manufacturer’s program tells us to push. If you’re weighing options, start with CGI sales & service to see the full scope of what we handle.
Why Casselberry Residents Choose Us for CGI Service

CGI builds a serious impact window. The Estate Collection and Sentinel Series carry real wind-load ratings, and the aluminum frames are thicker than what you’ll find on bargain vinyl. That matters in Casselberry, where summer storms roll in fast and the distinction between a window that holds and one that doesn’t is measured in inches of water on your living room floor.
Luca Romano, our owner and lead contractor, trained in structural work at Los Angeles Trade-Technical College and has spent nearly two decades applying that training across Central Florida. He’s the one who walks the job before we quote it, because a CGI window on a 1970s slab-on-grade home in Casselberry behaves differently than the same window on new construction in Orlando. The crew shows up background-checked and uniformed, you get photo updates before and after, and the written price you approve is the price on the final invoice. That’s how we run every job under The Relay Standard. For a full picture of where we work, see our Casselberry service area page.

Common CGI Construction Problems We Solve in Casselberry
CGI products are well built, but Casselberry’s climate and housing stock create specific failure patterns. These are the ones we see most often:
- Corroded weep hole covers causing water intrusion. Weep holes let condensation drain out of the window track. In older Casselberry homes, the original covers corrode from years of humid air and storm-driven rain, then clog with silt. Water backs up, seeps past the frame, and stains the drywall below. We replace the covers with new OEM parts and clear the full drainage path.
- Swollen weatherstripping on Estate Collection windows losing its seal. High humidity makes the original weatherstripping swell and deform, especially on south- and west-facing walls. You’ll feel the draft and see the energy bill climb. We re-seal or replace the stripping so the window actually closes tight again.
- Delaminating or cloudy laminated glass on pre-2000 CGI impact windows. Older interlayers break down under years of Florida UV exposure. The glass clouds, and the impact rating is compromised. This is a replacement job, not a repair, and we’ll tell you that straight.
- Racking CGI sliding glass door frames from Casselberry’s shifting clay soils. The soil here moves with the wet and dry seasons. Doors rack, rollers bind, and tracks wear unevenly. We re-square what we can and replace the rollers and track when we can’t.
- Failed sill flashing on windows in flood-prone zones. In the Lake Kathryn basin, hydrostatic pressure and standing water test the bottom of every window. When the original flashing fails, water works its way under the sill and into the wall cavity. We pull the window, install new peel-and-stick membrane, and reset it properly.
CGI Service in Casselberry: What Local Conditions Mean for Your Equipment

Casselberry’s Lake Kathryn neighborhood sits in a flood-prone basin where the water table is less than three feet below grade. That’s not a trivia fact, it changes how we spec CGI work. When groundwater sits that close to the surface, any window or door frame near grade faces constant moisture exposure from below, plus wind-driven rain from above. We specify CGI’s heaviest-gauge aluminum frames and stainless steel hardware for homes in that basin, because the standard hardware will corrode faster than it would in cities like Winter Park or Oviedo, where the water table sits deeper and drainage runs off more quickly. If your home backs up to one of Casselberry’s lakes or sits low on Queen’s Mirror Road, this is the single most important selection decision you’ll make.
Last August, our crew was called to a 1970s single-family home on Queen’s Mirror Road in the Lake Kathryn area. The homeowner had three original CGI Estate Collection windows leaking at the corners after a tropical storm. We found the weep holes clogged with silt and the sill flashing corroded through. We removed all three windows, replaced the flashing with new peel-and-stick membrane, installed new OEM weep hole covers, and resealed the frames. Since then, even the heaviest downpours haven’t put a drop inside. That’s the difference between knowing CGI products and knowing how they behave in Casselberry specifically.
CGI Models & Products We Service in Casselberry
We service the full CGI window and door lineup you’re likely to find in Casselberry homes: the Estate Collection impact windows, the Sentinel Series, the Targa Series impact-resistant windows, and Estate Collection sliding glass doors. For repairs, we use genuine CGI replacement parts whenever possible, especially for impact-rated glass and locking mechanisms. Aftermarket components may not maintain the same structural integrity, and that’s not a corner we’re willing to cut on a window that’s supposed to protect your family. When OEM parts are discontinued on older units, we’ll recommend a full replacement over a patch repair, because a patched window won’t restore the original wind-load and water-resistance rating. For service outside Casselberry proper, our CGI service in Orlando page covers the broader metro.

FAQs – CGI Construction in Casselberry
My Casselberry home has original CGI impact windows from the early 2000s. Can they still pass a wind mitigation inspection today?
It depends on the specific model, the condition of the laminated glass interlayer, and whether the original installation records exist. Early-2000s CGI windows can often pass if the glass isn’t delaminated and the frames are still square, but many we inspect in Casselberry fail on corroded weep covers and worn weatherstripping, not the glass itself. Call (850) 809-0306 and we’ll do a hands-on assessment before you schedule an inspection.
Do CGI windows hold up better than other brands against Casselberry’s high water table and flooding?
The window brand matters less than the installation details and hardware spec. CGI’s heavier aluminum frames hold up well in wet conditions, but even a CGI window will leak if the sill flashing fails or the weep system is clogged. In Casselberry’s flood-prone neighborhoods, we pair CGI frames with stainless steel hardware and upgraded flashing, and that combination is what actually holds up over time.
Can you repair a CGI sliding glass door that sticks constantly in a 1980s duplex near Sausalito?
Yes. Sticking is almost always a racked frame or worn rollers, and both are repairable if we catch them before the track is destroyed. In Casselberry’s older duplexes, shifting clay soil is the usual cause, and re-squaring the frame plus replacing the rollers gets the door sliding clean again. If the track itself is shot, we’ll show you the damage and quote a replacement track rather than telling you to live with it. Call (850) 809-0306 for a free look.
What’s the best way to stop condensation forming on the inside of my CGI windows during Casselberry’s humid summers?
Condensation on the inside pane means the indoor humidity is too high relative to the glass temperature. In Casselberry, that’s usually an HVAC or ventilation issue, not a window defect-though if the problem persists, Casselberry Bathroom Remodeling with proper exhaust upgrades can often solve it. We’ll check the window’s seal first to rule out air leakage, but the long-term fix is usually better bathroom exhaust fans, a dehumidifier, or adjusting the AC’s humidity set point, not replacing the glass.
How do I know if my CGI windows are still under warranty if I’m not the original homeowner?
CGI’s warranty is tied to the original purchaser and is generally not transferable to a second owner unless specific conditions were met at the time of sale. Your best move is to have the glass codes and serial numbers photographed, then have us help you determine the manufacture date. From there, the original warranty terms in your paperwork will tell you what’s covered. We won’t sell you a replacement you don’t need just because the warranty lapsed. Call (850) 809-0306 and we’ll check what you actually have.
