CGI Home Additions & ADU: The Orlando Owner’s Guide
If you’re reading this, you’re likely dealing with a CGI home addition or ADU component that’s worn out, cracked, leaking, or simply stopped doing its job. Mason Remodeling Co Orlando stocks and installs CGI-compatible parts for additions and accessory dwelling units across Orlando, with most replacement jobs running between $45,000 and $130,000 installed depending on scope, structural requirements, and finish level. We’re an independent service provider, not affiliated with CGI, but we’ve worked on enough of their product lines to know exactly what matches and what doesn’t.
Most Orlando homeowners discover a problem the way you just did: a door that no longer seals against summer humidity, a window frame showing water stains after an afternoon thunderstorm, or trim that’s pulling away from the wall because the original installation didn’t account for Florida’s moisture cycles. The good news is that CGI builds a solid product. The bad news is that no product survives Orlando’s heat, humidity, and hurricane season without maintenance, and when parts fail, they tend to fail in predictable ways.
Which CGI Models This Applies To
CGI’s home addition and ADU component lines span several series, and matching the right part means knowing what you’re looking at. The most common CGI products we service in Orlando are their impact-rated window and door systems, which carry model identifiers on a label typically located on the frame edge or the top of the door panel. Write down that series number before you call anyone. It’s the difference between a part that fits and a part that gets returned twice.
The real compatibility gotcha with CGI is that their impact-rated components are engineered as a system, not as standalone parts. A window sash from one CGI series will not necessarily seat correctly in a frame from another series, even if the rough opening measurements are identical. That’s why we always verify the series label and take physical measurements before ordering. On the OEM-versus-aftermarket question: for structural components like door frames, window sashes, and mullions, we recommend OEM CGI parts every time. For consumables like weatherstripping, rollers, and balance springs, quality aftermarket equivalents from manufacturers like Prime-Line and Caldwell perform just as well at a lower price point. We keep common CGI-compatible consumables on our trucks in Orlando, so a service call often ends the same day it starts.
One more thing worth knowing: CGI’s Florida-market products are built to Miami-Dade County standards, which means the fasteners, anchors, and flashing details are specific. Using generic hardware store fasteners on an impact-rated assembly voids the product rating and, in some Orlando jurisdictions, fails inspection. We’ve seen it happen. It’s an expensive lesson that takes about ten minutes to avoid.
Styles & brands we work with
Signs Your CGI Home Additions & ADU Is Failing
- Condensation between glass panes in impact windows. The hermetic seal has failed, which means the insulating gas has escaped and the window can no longer perform to its original energy or impact rating. In Orlando’s humidity, this shows up as fog you can’t wipe away from either side.
- Doors that stick, drag, or require a shoulder to latch. This usually means the frame has settled or the hinges have worn past their adjustment range. Central Florida’s sandy soil shifts more than people expect, and that movement transfers directly into door frames on additions and ADUs.
- Water staining at window corners or along the base of exterior walls. The flashing or sealant has degraded. Orlando gets roughly 51 inches of rain a year, most of it in hard afternoon storms, and a failed seal shows itself within one season.
- Visible rust or corrosion on fasteners and hardware. Salt air from the coast reaches farther inland than most people think, and combined with humidity, it eats hardware faster than CGI’s warranty period accounts for. We regularly replace corroded hinges and track assemblies on ADUs built less than a decade ago.
- Cracks in caulking or joint sealant around windows and doors. This is the early warning sign most homeowners ignore. Once sealant cracks, water gets behind it, and the repair cost compounds quickly. If you catch it early, it’s a $200 fix. If you catch it late, it’s a frame replacement.

AfterReplacement Cost & What’s Included
For a full home addition in Orlando, you’re looking at $45,000 to $130,000 depending on square footage, foundation type, roof tie-in complexity, and interior finish level. ADU construction runs $90,000 to $220,000, which reflects the cost of adding a second dwelling unit with its own utilities, kitchen, and bath on an existing Orlando lot. Garage conversions fall between $30,000 and $80,000 depending on whether the existing slab passes inspection and how much electrical work the conversion requires.
Every quote from Mason Remodeling Co Orlando includes a written price before any work starts, and that price is broken down by line item: materials, labor, permits, and any subcontractor work. If a part needs replacing mid-project and that part wasn’t in the original scope, you’ll see the change order in writing before we buy it. No verbal estimates that grow. No end-of-job surprises.
Our work carries a written guarantee with clearly stated terms, and that guarantee runs for 365 days from the completion date. If something fails within that window, we make it right at no cost to you. That’s the 365-Day Done Right Promise, and it applies to every addition and ADU project we complete in Orlando.
DIY or Call Us?
Here’s the honest split. There are things you can safely check yourself: weatherstripping that’s visibly torn or pulled away, caulking that’s cracked, drain holes in window tracks that are clogged with debris. Those are inspection tasks, not repairs, and knowing what’s wrong before you call saves everyone time.
What you should not DIY is anything involving structural fasteners, window or door removal, flashing, or impact-rated assemblies. These components are heavy, under tension, and tied to your home’s structural envelope. A window sash that drops during removal can break bones. A door frame that’s improperly shimmed will bind within months. And any work that alters the exterior envelope of your home in Orlando requires a permit, which means a licensed contractor has to pull it. We do that as part of every project, and we pass inspections before we call the job done.
If you’re not sure whether your situation is a check-it-yourself or a call-us situation, call us anyway. Tell me what the problem is. We’ll figure out the rest from there. Our number is (850) 920-7745.
FAQs
CGI’s impact-rated components are built for Florida, and with proper installation you can expect 15 to 20 years of service from frames and sashes, though hardware like hinges, rollers, and weatherstripping typically needs replacement every 5 to 8 years because of Orlando’s humidity and heat. Call (850) 920-7745 if you want us to assess the life left in your specific components.
Yes, if the failure is in the hardware, sealant, or weatherstripping, we repair it on-site, often the same day, and the repair is usually under $500. If the frame itself is cracked, rotted, or out of square, replacement is the only honest fix, and we’ll show you exactly why before you spend a dollar. Estimates are free, so call (850) 920-7745 to schedule one.
Most hardware and sealant replacements take 1 to 3 hours on-site, assuming we have the part on the truck, which we usually do for common CGI consumables. Full window or door replacements take 3 to 7 days from order to installation depending on CGI’s current lead times, and we’ll give you a firm written timeline before you commit. Call (850) 920-7745 and we’ll tell you what’s realistic for your specific series.
We stock common CGI-compatible consumables like rollers, weatherstripping, balance springs, and hardware on our trucks in Orlando, so many repairs are completed in a single visit. For series-specific structural components, we order direct from CGI or their authorized distributors, and we handle that ordering process for you so you’re not chasing part numbers. Call (850) 920-7745 with your series number and we’ll tell you same-day availability before you schedule anything.
Mason Remodeling Co Orlando also stocks and services components from KraftMaid, Cambria, and Silestone, so if your addition or ADU mixes product lines, we can handle the whole job without sending you to three different contractors.
