Mr-Glass Construction in Woodland Hills, CA | Mason Remodeling Co Woodland Hills
We provide independent Mr-Glass installation, repair, and retrofit service across Woodland Hills, from the flats north of Ventura Boulevard up into the canyon lots south of it. The one thing that separates Mr-Glass work here from anywhere else in the Valley is the soil. Expansive clay moves under these hillside homes every wet winter and dry summer, and that movement shows up first in window frames, patio door tracks, and shower glass. Call (831) 290-6866 for a free estimate if your Mr-Glass windows or doors are binding, rattling, or leaking. We’re familiar with every Mr-Glass series that’s been installed in Woodland Hills over the last three decades, and we stock the OEM parts to fix them right the first time.
Why Woodland Hills Residents Choose Us for Mr-Glass Service

Most glass companies can swap a window. Few understand what a Mr-Glass 3000 Series window goes through on a west-facing wall in Woodland Hills when July hits 105°F for a week straight. We do, because we’ve pulled those units out, seen the glazing bead shrink, and put them back better than the original install. Isaac Pruett, our owner, learned his trade foundations at Los Angeles Trade-Technical College and spent years working projects near Warner Center and the surrounding Woodland Hills neighborhoods before founding this company. He’s walked enough hillside lots to know which houses will have settling issues and which won’t. Our crew shows up with the right OEM rollers, beads, and weatherstripping already on the truck, not a vague plan to “take a look.” We also offer Mr-Glass sales & service guidance for homeowners deciding between repair and replacement, and we’ll give you a straight answer either way.
Every technician arrives background-checked, uniformed, and with photo ID. That’s the Threshold Standard we’ve held since 2004. You’ll know exactly who’s coming to your door before they knock, and the price is in writing before any work starts.

Common Mr-Glass Construction Problems We Solve in Woodland Hills
Here’s what we see most often on Mr-Glass products in this part of the San Fernando Valley:
- Vinyl glazing bead shrinkage on 3000 Series windows. South- and west-facing units bake in Woodland Hills summers. The vinyl bead contracts over years of triple-digit heat, the glass loosens, and you get drafts and rattles. We replace the bead with OEM material and reseat the glass properly.
- Roller and track wear on 5000 Series sliders from foundation settling. Expansive soils under hillside homes shift seasonally. That movement misaligns the sash, which grinds the rollers down and chews the track. Rebuilding the roller assembly usually fixes it if the frame is still square.
- Failed glazing tape on 9800 Series patio doors. Woodland Hills swings 40°F between day and night in fall and spring. That expansion and contraction cycle eventually breaks the polyurethane glazing tape seal, and air and water start getting in around the glass. We reglaze and reseal with materials rated for this climate.
- Stress cracks in 7500 Series fixed picture windows on unbolted stucco homes. Homes built from the 1950s through the 1970s often lack seismic bolting. During a Santa Ana wind event or minor temblor, the frame racks and transfers load straight into the glass corners. We see corner cracks start small and spread fast.
- Frameless shower enclosure misalignment in hillside bathrooms. Older hillside homes settle unevenly. Walls go out of plumb by an eighth-inch or more, and frameless glass panels start to bind or gap. We measure, shim, and hang the glass so it works even when the wall isn’t perfect.
Mr-Glass Service in Woodland Hills: What Local Conditions Mean for Your Equipment

Here’s something most people don’t realize until they own a home here: Woodland Hills sits at the western edge of the San Fernando Valley, right where Ventura Boulevard starts climbing into the Santa Monica Mountains. Los Angeles Municipal Code Section 91.7006 governs hillside grading in this exact area, and it requires special foundation setback and drainage details for any window or door enlargement. That means a Mr-Glass patio door replacement on a canyon lot often triggers a soils engineer and a sheer-wall upgrade that flatland contractors never have to pull. We’ve done those retrofits on homes in the hills south of Ventura where the lot is steep, the setback is zero-lot-line, and material delivery means a crane or a very careful hand-carry up a switchback. That’s not a complication for us. It’s just what the job requires. We pull the permits, we build the sheer wall if the engineer calls for it, and we install the door so it actually performs on a slope, not just on paper.
Last August our tech was called to a 1965 ranch on Sale Avenue in the Woodland Hills foothills where a Mr-Glass 9800 Series patio door was binding and letting in hot wind. The homeowner had a failed roller and warped vinyl shoe from years of expansion. We replaced the OEM roller assembly, shimmed the header for a 3/16-inch reveal, and resealed the perimeter with butyl tape. The door now slides with two fingers and doesn’t rattle during Santa Ana gusts. That’s the kind of fix you get when the crew knows both the product and the hill it’s sitting on.
Mr-Glass Models & Products We Service in Woodland Hills
We work on the full Mr-Glass residential lineup, including the 9800 Series hinged patio doors, 3000 Series horizontal rolling windows, 7500 Series fixed picture windows, and 5000 Series dual-pane sliders. We stock OEM replacement rollers, glazing beads, weatherstripping, and handle sets for these series because Mr-Glass extrusions and screw bosses are proprietary. Aftermarket copies bind or leak, and we won’t install parts we wouldn’t put in our own homes. If the frame is square and the glass is intact, we’ll rebuild the sash, replace the hardware, and reseal. If the insulated glass unit has failed or the vinyl is sun-baked beyond saving, we’ll tell you a full replacement is the better money. We also handle impact window installation, full window replacement, and frameless glass shower enclosures for Woodland Hills homes.

FAQs – Mr-Glass Construction in Woodland Hills
Yes, in many cases they do. Woodland Hills hillside lots fall under LAMC Section 91.7006 grading regulations, which can require specific drainage and flashing details that flatland areas don’t trigger. We inspect the existing rough opening and specify flashing that handles both wind-driven rain and the thermal cycling that Woodland Hills’ hot summers create. Call (831) 290-6866 to have us check yours.
A properly installed 9800 Series door with intact glazing tape, sound rollers, and good perimeter sealing will hold up. The failures we see in Woodland Hills are almost always installation or age-related, not inherent to the door. The key is that the frame is anchored square and the weatherstripping isn’t dried out. We can assess yours during a free estimate.
It depends on how far the frame has moved. If the corners are still square and the glass is intact, rebuilding the roller assembly and resetting the sash usually restores smooth operation at a fraction of replacement cost. If the frame itself has racked, we’ll be straight with you about that. Call (831) 290-6866 and we’ll take a look.
Yes, we see it regularly in Woodland Hills. Homes from the 1950s – 1970s without foundation bolting and cripple wall bracing transfer seismic and wind load into the window frames. The 7500 Series fixed units are especially vulnerable at the corners. Adding seismic retrofitting before or during window replacement prevents repeat failures.
We measure the actual wall profile, not the assumed one, then shim the mounting channel so the glass hangs plumb and the door swings true. It’s a detail-oriented job, and it’s the difference between Bathroom Remodeling in Woodland Hills that leaks at the hinge and one that doesn’t.
