Mr-Glass Sliding & Patio Doors: The Davie Owner’s Guide

We stock and install Mr-Glass-compatible sliding and patio door systems in Davie, with typical installed prices running $1,800-$4,200 depending on panel size, impact rating, and whether the existing frame can be retrofitted or needs full replacement. Most Mr-Glass hardware and roller assemblies we carry on the truck, and full panel replacements usually ship within 3-5 business days. Most Davie homeowners realize something’s wrong when the door starts sticking in the track during humid mornings, or when they notice the locking mechanism no longer draws the active panel tight against the weatherstrip.

Which Mr-Glass Models This Applies To

Mr-Glass produces several sliding and patio door series, and the parts are not interchangeable across all of them. The most common we see in Davie are the MG-5000 non-impact vinyl slider, the MG-Impact 70 aluminum-framed impact-rated system, and the MG-Elite thermally broken aluminum line. The series designation is stamped on the spacer bar between the glass panes, visible when you open the door and look at the edge of the glass. If that label is worn, measure the frame depth: the MG-5000 uses a 2-5/8 inch frame, the MG-Impact 70 uses 3-1/4 inches, and the MG-Elite runs 3-1/2 inches.

We source OEM Mr-Glass rollers, tandem assemblies, and locking mechanisms directly. For weatherstrip and screen mesh, we often recommend quality aftermarket equivalents that match the OEM compression specs at lower cost. One compatibility gotcha: the MG-Impact 70 uses a proprietary mortise lock with a 7-5/8 inch faceplate; standard 7-1/2 inch aftermarket locks will leave a visible gap and compromise the impact rating. We verify this measurement on every MG-Impact 70 service call in Davie.

Signs Your Mr-Glass Sliding & Patio Doors Is Failing

• The door requires shoulder weight to move. This usually means the tandem roller assembly has flattened or the axle has corroded. In Davie’s coastal humidity, we see roller failure at 6-8 years on non-impact vinyl units, faster if the track collects irrigation runoff.
• Visible gap at the center stile when “closed.” The mortise lock or keep has worn, or the door has sagged on failed rollers and no longer aligns with the jamb. A misaligned lock stresses the handle mechanism and will eventually snap the internal cam.
• Water pooling on the interior track after rain. The weep holes are clogged with debris, or the sill cap seal has separated from the frame. On older MG-5000 units, the vinyl sill cap can warp from thermal cycling and lose contact with the subsill.
• Fog between the glass panes that clears by afternoon. The insulated glass unit (IGU) has lost its argon fill and the desiccant is saturated. In Davie’s UV exposure, we see IGU seal failure most often on west-facing doors that get afternoon sun directly.
• The screen door jumps the track or drags. Screen roller housings on Mr-Glass units are plastic and crack under repeated impact. The screen frame itself may also be out of square if someone lifted it by the mesh rather than the frame.

Replacement Cost & What’s Included

What drives the range: frame condition (retrofit vs. full-frame), impact rating required, glass options (Low-E, tempered, laminated), and whether the existing subsill is level within 1/8 inch over the width. We pull permits when the frame is removed; Davie Building Department requires permit and inspection for full-frame replacement. Every job carries the 365-Day Done Right Promise under the Haven Standard, and the written quote you receive is the measured survey document we use to order.

DIY or Call Us?

What you can safely check: clean the track with a vacuum and damp cloth, clear weep holes with a pipe cleaner, and verify the door isn’t obstructed by shifted threshold trim. These are maintenance, not repair, and they solve more problems than most owners expect.

Where DIY goes wrong: the tandem roller assembly on a Mr-Glass slider carries 80-120 pounds of panel weight. Removing it without supporting the panel risks glass breakage or personal injury. The mortise lock interfaces with the multi-point locking system; incorrect installation can leave the door unsecured or damage the keep receiver in the jamb. We do not recommend homeowners remove or adjust impact-rated hardware, as improper reinstallation may void the product’s HVHZ certification.

We carry common Mr-Glass rollers, locks, and weatherstrip on our trucks in Davie. Call (754) 254-8492 and we’ll schedule a measured survey. You’ll keep the document, and the price on it is the price on the invoice.

FAQs

How long do Mr-Glass sliding door rollers last in Davie?

In Davie’s climate, expect 6-10 years on non-impact vinyl units and 8-12 years on aluminum impact-rated systems, assuming the track stays clean and the door isn’t overloaded with aftermarket security bars. Salt air within five miles of the coast accelerates corrosion; we see earlier failure in Harbor Islands and similar neighborhoods. Call (754) 254-8492 for an exact quote on replacement - estimates are free.

Can the door be repaired instead of replacing the part?

Some issues can be: a binding door often needs track cleaning and roller adjustment, not new rollers. But flattened roller wheels, cracked housings, or worn lock cams require replacement; lubrication or shimming is temporary and can damage adjacent components. We diagnose before ordering anything. Call (754) 254-8492 for an exact quote - estimates are free.

How long does a full panel replacement take?

Retrofit replacement of a single panel typically takes 2-3 hours; full-frame removal and replacement takes 4-6 hours, plus permit inspection scheduling. We arrive with the measured survey already completed, so the work day is uninterrupted. Call (754) 254-8492 to schedule your free estimate.

Do you stock Mr-Glass parts?

We stock rollers, tandem assemblies, mortise locks, handle sets, weatherstrip, and screen hardware for the MG-5000, MG-Impact 70, and MG-Elite series on our Davie trucks. Full panels and IGUs we order to measured specifications; they typically arrive within 3-5 business days. Call (754) 254-8492 to confirm availability for your specific model.

Measure it right the first time. Everything else follows from that. Sonia Raman built her process on that principle after seeing too many jobs in Pine Island Ridge go sideways from measurements taken in a hurry. Her crew has replaced full-frame Mr-Glass systems in Davie homes where the original retrofit quote turned out to be impossible once the drywall came back and revealed termite damage in the subsill. The measured survey catches what a phone estimate cannot.
