Why Casselberry Residents Choose Us for CGI Service

Most window companies in Seminole County learned their trade on wood-frame construction. Casselberry is not wood-frame. The core of this city was built out between the 1950s and early 1980s as solid concrete block ranch homes, and the original windows were set directly into those masonry openings. When a CGI frame fails here, the fix is different than it would be in a subdivision of vinyl-sided homes in Oviedo. We understand that difference because Dale Kessler, our owner, spent years measuring, setting, and sealing windows in CBS homes before he ever touched a wood-framed tract house. He grew up in Seminole Heights, learned the glazing trade at Hillsborough Community College, and has spent the better part of two decades doing storm-rated installation tight enough that a follow-up inspection never surprises anyone. That’s the standard we bring to every CGI job in Casselberry.

We’re the last call you need to make on a window or door. We keep OEM-compatible parts for CGI’s most common residential lines in stock, we register both manufacturer warranty layers in writing before the truck leaves your driveway, and every job carries a 90-Day Done Right Promise. If a repair isn’t done right, we make it right. No arguing, no paperwork games. Learn more about our CGI sales & service work across Central Florida.

Common CGI Windows & Doors Problems We Solve in Casselberry

CGI builds a solid impact-rated product. But Casselberry’s specific conditions create predictable failure points. Here’s what we see most often in this city:

• Aluminum frame oxidation and pitting on lakeside homes. Houses near Lake Triplet and Lake Concord sit in persistently humid air, and irrigation systems overspray window frames on a regular schedule. CGI’s aluminum frames hold up well, but after fifteen or twenty years the bottom rails and sill corners can start to pit. We clean, treat, and where the frame section is too far gone, recommend full-frame replacement instead of a patch job that buys you eighteen months.
• Failed corner seals on fixed picture windows. CGI’s fixed units are sealed with silicone at the corners, and on west-facing masonry walls in Casselberry that seal endures a daily thermal cycle: cold overnight, blazing afternoon sun, cold again. Over a decade or two, that cycle breaks the seal and you get fogging between the panes. We replace the sealed glass unit rather than the whole frame when the frame is still sound.
• Warped sliding door tracks on CGI 9500 Series sliders. Homes in the older lakeside neighborhoods of Casselberry often have slab-edge moisture that wicks up into the door frame from the bottom. That moisture corrodes the stainless roller assemblies and the track warps. The door drags, then binds. We quote threshold and track replacement together because fixing one without the other just sends you back to us in a year.
• Worn weatherstripping and misset strike plates on double-hung balance systems. The 1970s CBS homes throughout Casselberry still have their original CGI double-hung units in many cases. Summer afternoon thunderstorms push wind against those windows and any gap in the weatherstripping creates a whistle you can hear from the next room. We replace the balance system weatherstripping, reset the strike plates, and tighten the whole assembly so the window locks the way it was designed to.
• Jalousie-to-impact retrofits done wrong by other companies. We regularly arrive behind a previous installer who tried to drop a CGI impact window into an original jalousie opening without reframing the masonry. That installation will not pass a Seminole County Florida Product Approval inspection, and the homeowner paid for work that has to be redone. We reframe the opening properly the first time.

CGI Service in Casselberry: What Local Conditions Mean for Your Equipment

Here’s the thing a generic CGI page will never tell you. In the lakeside CBS neighborhoods south of Lake Triplet, ground moisture wicks up through the slab edge and into door frames from the bottom. Homeowners assume concrete block walls mean no moisture problems, so nobody looks at the threshold until the door starts dragging. By then the threshold, the frame bottom, and often the sill plate are rotting out together. We quote combined threshold-frame-and-door replacement so frequently in those neighborhoods that our technicians now check for it proactively before pulling a permit on any door job near Lake Triplet or Lake Concord. That’s Casselberry-specific knowledge. A crew from Longwood or Altamonte Springs might not think to look until the rot is visible. We do.

Our Casselberry service area coverage includes the original ranch-home neighborhoods where these problems are most common. We’ve been working these streets long enough that we know which blocks have the highest water table and which ones drain well. That’s not marketing. That’s just what you learn when you do honest work in one place for years.

CGI Models & Products We Service in Casselberry

We work on the full CGI residential lineup in Casselberry. That includes the Sentinel Series impact casement windows, the Estate Collection single-hung units, the 9500 Series fixed and picture windows, and CGI’s Sliding Glass Door Series. We keep a deep stock of CGI-specific glazing beads, locking hardware, sealed glass units, and weatherstripping for the Sentinel and 9500 Series, and we use OEM or specification-matching aftermarket parts for older Estate units. If your CGI frame section is heavily oxidized or the original opening cannot meet current Seminole County impact code with an insert retrofit, we will tell you honestly that full-frame replacement is the right move. We will not sell you a retrofit that fails inspection.
