Mr-Glass Home Additions & ADU: The Orlando Owner’s Guide
If you have a Mr-Glass home addition or ADU in Orlando that has developed a problem, we stock and install Mr-Glass-compatible parts and can typically complete the repair for $450 to $3,800 depending on what failed. Most owners call us after noticing a door that no longer seals, a window that fogs between panes, or a glass panel that has cracked from settling. You may also see water staining around the frame after one of Orlando’s afternoon downpours, which usually means the flashing or seal has given out.
We are an independent Orlando general contractor, not a Mr-Glass dealer or affiliate. That matters because we are not tied to one manufacturer’s price list. We match the part to your existing unit and give you an honest choice between OEM Mr-Glass components and quality aftermarket equivalents that often cost 30 to 50 percent less for the same fit and finish.
Key Takeaways
- Mr-Glass addition and ADU repairs in Orlando typically run $450 – $3,800 installed, with full glass panel or frame replacements at the higher end.
- We keep common Mr-Glass door rollers, seals, and glazing channels on the truck, so many repairs finish in one visit.
- Written price before any work starts, every time. No verbal estimates that creep upward.
- If a repair fails within 365 days, we return and make it right at no charge under our Done Right Promise.
Which Mr-Glass Models This Applies To
Mr-Glass products used for home additions, sunrooms, and ADUs in Florida come in two broad families: the Series 400 thermally broken aluminum frames and the Series 600 impact-rated units required by Miami-Dade and many Orange County coastal-adjacent codes. The Series 400 is more common on older Orlando additions built before the 2017 code update. The Series 600 is what you will find on newer ADUs and any structure within a mile of the coast where wind-borne debris standards apply.
To confirm what you have, look for a silver label on the inside edge of the door or window frame. It will show the series number, the glass pack code, and a date of manufacture. If the label is missing, measure the glass thickness: Series 400 typically uses 1-inch insulated units, while Series 600 uses 1-and-1/8-inch laminated insulated glass. This is the compatibility gotcha that causes trouble. You cannot swap a Series 400 panel into a Series 600 frame and expect it to seal, even if the rough opening looks identical. The glazing channel depth is different.
For rollers and hinges, Mr-Glass used three generations of hardware. Gen 1 (pre-2010) parts are discontinued and have been for years. We use a proven aftermarket roller from a Florida supplier that carries the same 200-pound rating and fits Gen 1 tracks without modification. Gen 2 and Gen 3 Mr-Glass hardware is still obtainable as OEM, and we stock the common sizes in our Orlando shop.

Signs Your Mr-Glass Home Addition or ADU Is Failing
- The door drags or sticks in the track. This is almost always a roller failure. Florida humidity accelerates corrosion on the steel bearings, and once one roller seizes, the door starts wearing the track. You will hear a grinding sound if you listen close.
- Condensation or fog between the glass panes. The insulated glass unit has lost its seal. In Orlando, a seal that fails in April will fog heavily by July because our humidity pushes moisture into the air gap through the failed edge seal.
- Water on the floor after heavy rain. The sweep gasket at the bottom of a sliding glass door is a wear item. It gets flat and brittle from UV exposure in about five to seven years here, and once it goes, a wind-driven rain pushes straight under the panel.
- The frame feels loose or you can see daylight at the corner. Fasteners have backed out or the concrete slab has shifted. Central Florida’s sandy soil settles, and additions built on slab foundations commonly see corner settling within the first three years.
- The lock no longer engages smoothly. When a door sags even an eighth of an inch, the latch misaligns with the strike plate. This is often a worn roller plus minor track wear combined, not just a lock problem.

AfterReplacement Cost & What’s Included

Every price includes the part, labor, disposal of the old material, and cleanup. You get a written price before we touch anything, and that price does not change unless we find a structural issue we could not see on the surface, in which case we stop, show you what we found, and get your approval before spending another dollar. Our work on Mr-Glass repair carries the same 365-Day Done Right Promise as every other Mason Remodeling Co Orlando project: if it is not right within a year of completion, we fix it at no cost to you.
DIY or Call Us?
There are two things an owner can safely do before calling. Inspect the track for debris and wipe it clean with a dry cloth. And check the sweep gasket for visible cracks or flat spots. If those are fine and the door still sticks, stop there. Working on a sliding glass door panel means handling a 60-to-140-pound piece of tempered glass under tension from the roller assembly. The panel can shift unexpectedly, and if a finger is in the wrong place, you are looking at a serious injury. This is one area where the cost of a pro is cheaper than the cost of a hospital visit.
If you are in Orlando and your Mr-Glass door or panel is failing, call (850) 920-7745. Tell us what the door is doing, we will tell you what we think it is, and we will give you a written price before anyone shows up at your door.
FAQs
In Orlando’s heat and humidity, expect 10 to 15 years from the frame and 7 to 10 years from the rollers and seals before something needs attention. Coastal-adjacent homes and ADUs with direct afternoon sun exposure trend toward the shorter end. Call (850) 920-7745 and we can tell you what shape your unit is in with one visit.
Rollers, seals, locks, and tracks can be repaired or rebuilt. A glass panel that has lost its seal or cracked cannot be repaired. The insulated unit has to be replaced as a single assembly. We will show you the difference and give you both options in writing before you decide.
Roller and seal replacements usually take 45 to 90 minutes per door. Insulated glass unit replacement takes one to two hours plus the lead time to fabricate the unit, which in Orlando is typically three to five business days for standard glass and five to seven for impact-rated panels. We will give you a firm window when we quote the job.
We carry common Mr-Glass Gen 2 and Gen 3 rollers, sweeps, glazing channels, and track shims, plus aftermarket equivalents for discontinued Gen 1 hardware. Approximately 70 percent of the Mr-Glass repair calls we run in Orlando finish on the first visit. If we need a fabricated part, we order it the same day and schedule your install as soon as it lands in our shop. Call (850) 920-7745 and we will confirm what we have for your model.
