CGI Windows & Doors in St. Leo, FL | TruePane Windows & Doors
We provide independent St. Leo Window Installation and door service across St. Leo, from the Saint Leo University campus to the modest concrete-block homes along State Road 52. The work here differs from any neighboring town because so many CGI units sit inside 12 to 18 inch thick historic masonry walls that standard flanges will not bridge. We are not a CGI dealer and we are not manufacturer-affiliated, which means we answer to you, not to a brand quota. Call (813) 320-9346 for a straight answer about your windows.
Why St. Leo Residents Choose Us for CGI Service
The pool of contractors who actually know CGI hardware in St. Leo is thin, and the university knows it. Our crew has spent more than a decade working on CGI windows and doors here, including multiple projects inside Saint Leo University’s historic masonry buildings, where we have matched CGI’s StormPro and Estate Collection lines to openings that out-of-area crews mis-measure on the first visit. Dale Kessler, our owner, learned the glazing trade at Hillsborough Community College’s construction technology program and has spent the better part of two decades setting and sealing windows across the Tampa Bay area. His rule is simple: if the pane is not true, the job is not done.
Every CGI call in St. Leo gets a live person on the phone, not a voicemail tree. Our technicians are background-checked and uniformed. We measure twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves your driveway. That is The Keystone Standard, and it applies to every job from a single roller replacement to a full dormitory window package.
Common CGI Windows & Doors Problems We Solve in St. Leo
- Thermal seal failure in CGI insulated glass units. St. Leo sits near the Green Swamp watershed, where humidity hangs in still air. On campus buildings with 12 to 18 inch masonry walls, the IGU gets heat stress from the sunny exterior face and moisture from the interior stone, which kills seals faster than on thin wood-frame homes. We see fogged CGI units on campus regularly.
- Corrosion and pitting on CGI aluminum frames. Homes near Lake Jovita and the Green Swamp get sprinkler overspray on bottom rails, and St. Leo’s persistent humidity keeps that moisture in place. Anode breakdown shows up as white chalky pits on the bottom rail and corner joints. We replace gaskets, clean the extrusion, and when the pitting has gone too deep, we tell you straight that replacement beats repair.
- Sagging or binding rollers on CGI sliding doors. The 1970s through 1990s concrete-block homes around St. Leo collect sand and fine debris in door tracks. Under humid, still-air conditions that grit packs into the roller housing. We stock CGI OEM rollers and replace the assembly rather than lubing a worn bearing and hoping for the best.
- Warped or stuck CGI casement operators. College-owned housing around St. Leo often has original wood-frame openings that are slightly out of square. A factory-correct CGI jamb does not always seat cleanly in an opening that has shifted over forty years. We shim and re-square the operator mount rather than forcing the crank, which is how operators strip.
- Failed balance cartridges in CGI double-hung units. St. Leo’s older campus annexes and rental houses have windows that get opened and closed hundreds of times per semester. Balance cartridges wear, and when one side lets go the sash drops or won’t stay up. We carry OEM CGI balance cartridges for the Estate and Sentinel lines.
CGI Service in St. Leo: What Local Conditions Mean for Your Equipment
Only in St. Leo will you find a contractor regularly cutting CGI’s standard nailing flanges off and building a custom wood extension jamb so the frame can bridge Saint Leo University’s 12 to 18 inch thick abbey walls. No one in Dade City, Zephyrhills, or San Antonio ever sees this, because the abbey is the only masonry structure of that age and mass in Pasco County. Founded in 1889, the Benedictine campus predates Florida’s modern building codes by a century, and its deep-set window openings were built for single-pane wood sashes, not flanged replacement windows. That means a standard CGI impact window cannot simply be nailed to the exterior face of the wall. The flange is too narrow to reach sheathing. We mill poplar extension jambs in our shop, set the CGI frame into the jamb, and trim the interior to match the original profile. It is restoration work, not just replacement, and it requires a shop that understands both CGI’s product line and the wall it is going into.
Last fall our crew pulled a dozen CGI Estate Collection double-hungs out of an 1890s chapel annex on the Saint Leo University campus after the original single-pane wood sashes finally gave out. The rough openings were over 14 inches deep, so we milled custom poplar extension jambs in the shop, ordered non-standard S4S interior trim to match the existing profile, and set the new CGI Sentinels with a full-perimeter sealant joint that passes Florida Product Approval at the required wind pressure for that exposure. The university’s facilities director later asked us to spec the same approach for four more buildings on the same stone wall line. That is the kind of reference that matters in a town this small.
CGI Models & Products We Service in St. Leo
We service the full CGI residential line that shows up in St. Leo: the Estate Collection single-hung and double-hung, the Sentinel Series casement and picture windows, the Targa Series sliding doors, and the Estate Tilt & Turn line. For parts we use OEM whenever they are still available, which includes gaskets, rollers, balance cartridges, operator assemblies, and hinge kits. Aftermarket hardware often changes the reveal or frame alignment in those thick historic openings, and that causes binding. We stock common CGI rollers and balances for fast turnaround in St. Leo, and we can source the rest quickly because we buy direct from CGI’s distribution network, not through a middleman.
If your CGI unit is older than 15 years with a failed seal or corroded frame, we will likely recommend full replacement rather than a patch. Re-sealing and refinishing an old CGI frame in St. Leo’s humidity rarely pays off. We will show you the numbers side by side, in writing, before you commit to anything. Our CGI sales & service team handles the full range of repair and replacement work.
CGI Service Pricing in St. Leo
CGI service pricing in St. Leo depends on what failed and where the window sits. A simple roller replacement on a Targa sliding door runs less than a full jamb rebuild inside a 14 inch abbey wall. Here is what you should expect:
- Roller replacement (CGI Targa sliding door): $95 to $215 per door, OEM rollers and track cleaning included.
- Balance cartridge replacement (CGI Estate double-hung): $60 to $140 per sash, depending on weight rating and access.
- Casement operator replacement (CGI Sentinel): $110 to $230 per window, OEM operator and hardware.
- Insulated glass unit replacement (single IGU, any CGI line): $180 to $420 per sash, depending on size and Low-E coating.
- Full CGI window replacement in a standard St. Leo home: $700 to $1,400 per opening installed, depending on impact rating and jamb work.
- Historic jamb rebuild and custom extension work (campus-style masonry openings): $350 to $900 per opening, shop-milled poplar jambs and trim to match existing profiles.
We give free written estimates with line-item pricing, and we honor the number we write down. The standard offers are a free written repair estimate, a maintenance check, and a permanent 5% discount for seniors and veterans.

FAQs - CGI Windows & Doors in St. Leo
Yes. We remove the standard CGI nailing flange, build a custom wood extension jamb sized to the actual wall depth, and set the CGI frame inside that jamb with a full-perimeter structural sealant joint. The opening does not need to be rebuilt, widened, or structurally altered. This is the same approach we have used on multiple Saint Leo University buildings, and it maintains the original interior and exterior trim profiles while meeting current Florida Building Code wind-load requirements. Call (813) 320-9346 if you have a specific building in mind, and we will look at the opening and give you a written plan.
St. Leo sits inland near the Green Swamp watershed and Lake Jovita, where humidity lingers in still air and sprinkler overspray settles on bottom rails without drying out the way coastal breezes dry Tampa. Tampa’s proximity to the Gulf means more salt exposure but also more airflow, which evaporates standing moisture. St. Leo’s humid, still-air conditions keep water on the aluminum longer, which accelerates anode breakdown and pitting. Bottom rails fail first, almost always where irrigation water hits the frame.
The manufacturer warranty covers the CGI window or door unit itself, including glass, frame, and hardware, for the duration stated by CGI. Our workmanship is covered separately by our 90-Day Done Right Promise, which is in writing and requires no argument if something is not done right. We register both warranty layers before the truck leaves the driveway. Work on university property is covered the same way as a private home, and we are happy to put the warranty terms in writing before any work begins. If it needs to be in writing to be true, we will put it in writing.
Yes, if the property is owned or managed by Saint Leo University, you need approval from the university’s facilities or housing office before any window or door work begins. We have worked with their facilities director on multiple buildings and understand their submittal and inspection process. We can prepare the product specs, wind-load documentation, and installation details they will ask for. Call (813) 320-9346 and we will walk you through what the university will need from you.
St. Leo falls under Pasco County’s Florida Building Code wind-speed requirements, which apply to inland properties and mandate wind-rated or impact-rated assemblies for any permitted replacement work. The exact design pressure rating depends on your building’s exposure category, height, and location relative to open water and tree canopy. We calculate the required rating for each opening during the estimate and spec the CGI model that meets it, no guesswork. For campus and historic masonry buildings, we typically specify CGI Sentinel or Estate units sized to the wind pressure for that specific exposure. Call (813) 320-9346 and we will tell you the required rating for your building.
