Why Trust TruePane Windows & Doors for Your Mr-Glass Windows & Doors?

Our crew has field-serviced Mr-Glass MG760, MG770, MG780, and MG790 lines from Boca Teeca to Addison Reserve, and we know what these frames do after ten years of salt air and afternoon downpours. Dale Kessler grew up in the Boca Teeca neighborhood of Boca Raton, where his father spent weekends replacing jalousie windows in every house on the block and never once called it a hobby. After finishing his glazing and fenestration coursework at Palm Beach State College in Lake Worth, Dale spent the next two-plus decades measuring, setting, and sealing windows and doors across Palm Beach County. That local heritage means our technicians measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves the driveway. If the pane is not true, the job is not done.

We carry a local stock of Mr-Glass-compatible balance springs, roller assemblies, meeting-rail hardware, and weatherstripping so most repairs finish in a single visit. Background-checked, uniformed technicians arrive when we say they will. We stand behind the work in writing.

Common Mr-Glass Windows & Doors Problems We Fix in Boca Raton

Boca Raton’s direct Atlantic coastline and Intracoastal frontage subject aluminum frames and door hardware to chronic salt-air oxidation. Mr-Glass windows are well built for the Florida market, but we see the same model-specific failure patterns repeat across east Boca neighborhoods, and they rarely match what a national brand page describes.

• Weep-hole blockages in MG760/MG770 sill tracks. The MG760 single hung and MG770 double hung have narrow weep channels at the sill base. In Boca Raton, wind-driven rain pushes fine sand, pollen, and salt residue through the exterior track, and those weep holes clog. Water then pools in the sill track and leaks past the interior sash onto lower-level tile or carpet. We clear the channel without distorting the frame, then replace the weep cover if the original has degraded. The symptom is water on the interior sill after rain, even when the sash sits closed and locked.
• Stripped or corroded stainless-steel balance springs in MG770 double hungs. After repeated exposure to salt-heavy air, the balance springs inside MG770 side jambs lose tension or the mounting points corrode. The sash becomes heavy to lift and then drops suddenly when released. We replace the balance assemblies with OEM-rated units and re-tension for the exact sash weight. Attempting to force a stiff double hung is a good way to snap the spring and let the sash drop.
• Misaligned interlocking meeting rails on MG780 horizontal rollers. The MG780 horizontal roller uses interlocking meeting rails that must align in plane. When the header sags or a roller wears unevenly, the rails shift slightly, leaving a draft and insect gap even when the sash looks closed. In Boca Raton, this is worse on Intracoastal-facing patios where salt corrosion seizes the top rollers. We re-shim the header, replace the rollers, and realign the rails.
• Fogging between panes in MG790 casement insulating glass units. Boca Raton’s combination of prolonged sun and humidity eventually breaks the factory edge seal on MG790 casement IGU units. The result is condensation between the glass that cannot be wiped off. A fogged unit is a failed seal, not a cleaning problem. We replace the sash IGU or the full sash depending on frame condition.
• Corroded roller assemblies on MG780 sliders facing the water. East of Federal Highway, especially within a half-mile of the Intracoastal, MG780 rollers pit and seize years ahead of west Boca units. The panel gets tight, then drops when forced. We replace with marine-grade stainless aftermarket rollers rather than factory originals, which in our experience perform better long-term in salt air.

Mr-Glass Parts & Our Repair-vs-Replace Approach

We use OEM Mr-Glass hardware where it affects structural or impact integrity, specifically sashes, meeting rails, and heavy-duty balance systems. For weatherstripping, rollers, and weep covers, we install quality aftermarket components when OEM lead times would leave a home unprotected, which they often do. Those aftermarket choices, particularly marine-grade stainless rollers, hold up better in Boca Raton’s salt air than the factory parts in our testing.

Our repair-vs-replace rule is simple. If a frame is square, a rail is recoverable, and the glass is sound, we repair. If the frame is pitted through, the meeting rail is beyond realignment, or an older non-impact Mr-Glass unit falls short of current Miami-Dade wind-load code, we recommend full frame replacement with a modern Mr-Glass impact line rather than a costly patch. We would rather tell you the honest truth than sell you a repair that fails in eighteen months. Call (561) 264-1337 and our technician will walk you through both options in plain numbers.

Our Mr-Glass Service Process - Step by Step

1. 1
   Diagnosis: The technician measures every opening twice, inspects the frame, sash, glass, seals, and hardware, and names the failure in plain English. For MG770 balance spring issues, that means checking both jambs, not just the side that feels heavy. You get a written line-item quote before any work starts, no surprise line items on the bill.
2. 2
   Repair or replacement: The technician repairs in place when possible or removes the old unit and sets the new Mr-Glass frame, sash, or IGU. Structural hardware goes in OEM, wear items go in quality aftermarket when it serves you better.
3. 3
   Testing: Every window is opened, closed, locked, and checked for plumb, level, and true alignment before the technician calls the job done. Water is run over the sill to confirm drainage, especially on MG760/MG770 weep systems.
4. 4
   Warranty registration: The Keystone Standard applies to every job. Both manufacturer warranty layers are registered in writing, with durations stated, before the truck leaves the driveway. The Done Right Promise means if it is not done right, we make it right, with no paperwork fights and no arguing.

One recent job pulled a pair of Mr-Glass MG780 horizontal rollers from a Boca Raton patio facing the Intracoastal. The meeting rails had shifted so far out of plane that one panel dropped off its track, and salt corrosion had seized both top rollers. We replaced the roller assemblies with marine-grade stainless aftermarket units, re-shimmed the header to correct the rail alignment, and reflashed the sill with a new weephole cover. The homeowner now slides both panels with two fingers, and the water leak that had stained the tile is gone.
