Mr-Glass door installation in Jacksonville typically runs between $480 and $1,450 installed, including the new glass unit, labor, and haul-away of the old panel. Most homeowners call us after noticing fog between the panes, a cracked lite, or a door that suddenly feels heavier and sticks against the frame. We stock common Mr-Glass glass pack sizes on the truck, so a straightforward swap is often done the same day we take measurements.
If you’ve got a Mr-Glass door with a failed seal or broken glass, the door frame itself is usually still in good shape. That’s the good news. The glass unit inside that frame is a replaceable component, and doing it right means matching the exact thickness, spacer color, and low-E coating that Mr-Glass used when the door was built. It’s work we’ve handled across Jacksonville, from Ortega bungalows to Mandarin ranch homes to the newer stucco builds out by the beaches.
At Lightwell Windows Jacksonville, we’re an independent service provider, not affiliated with Mr-Glass, so our recommendation is based on what fits your door correctly and what will hold up in Florida humidity, not on pushing a particular label. We carry Mr-Glass-compatible insulated glass units alongside products from PGT, CGI, and CWS when a full door replacement is the smarter call.
Which Mr-Glass Models This Applies To
Mr-Glass manufactures insulated glass units for sliding patio doors and hinged entry doors across several series lines, and the panel dimensions vary enough that eyeballing it won’t work. We measure glass thickness, overall panel size, and spacer bar style before ordering anything. The most common Mr-Glass units we replace in Jacksonville are in sliding glass doors: 60″ x 80″ panels, 72″ x 80″ panels, and the narrower 48″ sidelites that flank front entry doors.
One compatibility gotcha we run into often: two Mr-Glass doors that look identical from the living room can have different glass unit thicknesses, typically 7/8″ versus 1″ overall. Older sliding door panels from the early 2000s tend toward 7/8″, while newer builds after roughly 2015 are frequently 1″. If you put a 7/8″ unit into a frame milled for 1″, the glazing bead won’t seat correctly and the door will rattle against the weatherstripping. We check the actual frame channel before ordering.
There’s an identification sticker on the top edge of most Mr-Glass panels with a model number and date code. You’ll need a step stool to see it. If the sticker is worn off, which happens often after a decade of Jacksonville sun, one of our technicians will pull the door’s interior glazing stop and measure the unit directly.
On the OEM-versus-aftermarket question: for Mr-Glass doors, a high-quality J-V certified insulated glass unit from a regional fabricator performs essentially identically to the OEM unit, usually at a better price and faster lead time. We use a Tampa-based fabricator with a proven argon fill rate and low-E coating that meets Florida energy code. What matters most is matching the spacer bar color, the glass thickness, and the coating, not the sticker.
Styles & brands we work with










Signs Your Mr-Glass Door Installation Is Failing
- Fog or condensation between the panes. The inner seal has failed and the argon or krypton fill has escaped. In Jacksonville’s humidity, a broken seal shows up fast as trapped moisture that dries and re-fogs with temperature changes.
- Cracked or shattered glass with no impact point. Tempered glass occasionally fails from edge nicks during original installation or from frame settling over years. The break pattern tells us whether it’s a thermal stress crack or impact damage.
- Door drags or scrapes the track. When a door falls out of square, the glass panel shifts in the frame and can wedge against the glazing channel. Dragging is often a roller or alignment issue, but left too long it stresses the glass edges and leads to cracking.
- Visible bulging or bowing of the glass unit. A failed seal changes internal pressure and can bow the glass slightly outward. You’ll see a distorted reflection when stepping outside and looking at the door from an angle.
- Drafts or whistling around the door frame. If the glass unit has loosened within the frame, you’ll hear air moving around the edges on windy days. That movement also invites moisture into the channel, which accelerates frame rot on wood doors and corrosion on the glazing hardware.
Replacement Cost & What’s Included
Most Mr-Glass door glass replacements in Jacksonville fall between $480 and $1,450, depending on panel size, glass type, and whether the unit needs a full-frame replacement. A standard 60″ x 80″ sliding door panel runs $480 to $800 installed. Larger 72″ x 80″ units run $700 to $1,000. Sidelites are smaller but often labor-intensive due to tight framing clearances, typically $500 to $900. The upper end includes tempered glass, an upgrade to impact-resistant glazing where existing hardware permits, or door frames beyond salvage.
Every price includes the glass unit, glazing tape, new gaskets or glazing stops where needed, haul-away of the old glass, and cleanup. You get a written price before any work starts, of course. If there’s an unknown behind the frame, we take a photo, show you, and price the change before touching it. The workmanship carries our 365-Day Done Right Promise, so if the door isn’t right after the swap, we come back and make it right, no debate, no countdown.

What you can safely do: identify the door’s age, find the sticker on the top edge if reachable, and take a photo of the fogging or cracking. What you should not attempt: removing a tempered glass panel from a sliding or hinged door. The unit is heavy, carrying tension at the edges, and a mishandled tempered panel shatters into hundreds of small cubes. Scraping old glazing tape from a frame without properly supporting the door risks the entire panel collapsing onto the track or a person.
In Jacksonville’s salt air, frames near the Intracoastal also hide corrosion behind the glazing channel that needs a trained eye to spot before the new unit goes in. If you can safely remove the sticker and send us a photo, we can often give you a pricing range over the phone. Otherwise, one of our technicians will measure on site. Call (904) 914-3691 and we’ll take care of the rest.
FAQs
In Jacksonville’s heat and humidity, an insulated glass unit for a door typically lasts 12 to 20 years before the seal gives out, which is why most Mr-Glass door repairs we handle are on homes built between 2005 and 2015. Coastal homes near the beaches or the Intracoastal often see seal failure five to eight years sooner from the salt air. The frame itself can last the lifetime of the home with proper maintenance. Call (904) 914-3691 for an inspection if your door is passing the decade mark. Our estimates are free.
No. Once the inner seal breaks and moisture enters the air space, the glass unit is compromised permanently and cleaning the interior surface or resealing the edge does not restore the insulating performance. The entire insulated glass unit gets replaced. The cost is modest compared to a full door, and we usually complete the swap in a single visit. We’ll give you the exact number before anything is ordered.
A straightforward Mr-Glass glass panel replacement takes 90 minutes to two hours on site, once the unit is measured and ordered. If the unit matches what we stock on the truck, which is common for standard 60″ x 80″ sliding panels, we can often do it the same day we measure. Custom sizes or impact-rated upgrades take more time to fabricate.
We stock the most common Mr-Glass sizes for Jacksonville, which are 60″ x 80″ and 72″ x 80″ sliding door panels in both 7/8″ and 1″ thicknesses, plus common sidelite dimensions. If your door is an older or unusual size, we order from our fabricator with standard lead times. Either way, you’ll know the timing before we begin, and no payment is required until the work is complete and you’re satisfied.
