Mr-Glass Windows & Doors in San Francisco, CA | Juniper Windows & Doors
We service and repair Mr-Glass windows and doors throughout San Francisco as an independent contractor, not a manufacturer affiliate. The difference that matters here: our techs know how Mr-Glass frames, rollers, and seals actually behave in this city’s fog belt, onshore wind, and older housing stock. If you need Mr-Glass work in San Francisco, call (682) 281-2168 for a free estimate with a written price before anything starts.
Why San Francisco Residents Choose Us for Mr-Glass Service
Most San Francisco, CA window companies will happily sell you new windows. Fewer will open up a Mr-Glass horizontal roller, diagnose why it’s binding, and fix it without pushing a full replacement. That’s the work we do. Our crews have serviced Mr-Glass vinyl replacement windows, sliders, casements, and entry doors in San Francisco homes for years, and we carry OEM-equivalent rollers, sash locks, weatherstrip, and glazing gaskets so repairs don’t stall waiting on parts.
Sean Mackey, our owner, grew up around window work and has spent his career focused on building envelope fundamentals, the stuff that explains why a fogged Mr-Glass unit in the Outer Sunset fails differently than one in Potrero Hill. He’s built the business on a simple rule: if a number, timeframe, or trade-off belongs on the page, we put it there. No vague quotes, no surprise invoices. Every Mr-Glass service call in San Francisco gets a written price before we touch the window.
Common Mr-Glass Windows & Doors Problems We Solve in San Francisco
- Condensation and water inside hollow vinyl frames. In fog-heavy neighborhoods like the Sunset, Richmond, and Outer Parkside, the marine layer keeps Mr-Glass single-hung and double-hung frames wet for days at a time. Water works into the frame channels, pools, and eventually shows up as damp drywall or peeling paint below the window. We trace the intrusion point, clear blocked weep holes, and replace degraded gaskets.
- Roller failure and jumping tracks on horizontal sliders. On exposed hillsides like Twin Peaks and Potrero Hill, constant onshore wind pushes Mr-Glass 3-lite sliding doors off-kilter. OEM rollers flatten, the inner track bows, and the door starts catching or jumping. We pull the sashes, replace rollers with OEM-equivalent hardware, and re-tension the track.
- Drafty, whistling casement and awning windows on the west side. Salt air and ocean wind eat weatherstrip. Mr-Glass casement units facing the Pacific often develop gaps at the sash, letting in drafts and a whistle you can hear from across the room. New compression gaskets and a sash adjustment usually fix it.
- Fogged glass from thermal-pane seal failure. After 10 to 15 years, Mr-Glass insulated glass units on south- and west-facing elevations in San Francisco start losing their seal. The telltale sign: condensation between the panes that won’t wipe away. We source quality aftermarket insulating glass units when OEM glass is slow or discontinued.
- Sticking or leaking Mr-Glass entry and French doors. San Francisco’s temperature swings and settling soils cause door frames to shift slightly, throwing off the reveal. A Mr-Glass French door that sticks at the top or leaks at the sill usually needs hinge adjustment, weatherstrip replacement, and sometimes a threshold reset, not a full door replacement.
Mr-Glass Service in San Francisco: What Local Conditions Mean for Your Equipment
Here’s something most window pages skip: San Francisco’s Residential Design Guidelines and many neighborhood-specific historic requirements mean Window Replacement in San Francisco in the Sunset, Richmond, or Mission often has to match the existing recessed depth, trim profile, and visible sash configuration. A Mr-Glass vinyl insert that works great in a 1950s Daly City ranch can be the wrong call for a pre-war Edwardian on a Richmond block. We routinely measure setbacks, not just rough openings, before we order anything. It’s a small step that avoids a permit rejection or a window that sits proud of the stucco and looks wrong from the sidewalk. In the Outer Sunset, we had a homeowner with two Mr-Glass 3-lite sliding doors binding badly after years of onshore wind and grit in the lower track. Our tech pulled the sashes, found flattened OEM rollers and a bowed inner track, replaced the rollers with OEM-equivalent hardware, cleaned and re-tensioned the track, and re-set the weatherstrip. The doors now glide with one finger and don’t weep water during fog season.

FAQs – Mr-Glass Windows & Doors in San Francisco
Most of the time, it can be fixed. The usual culprit is flattened OEM rollers paired with a dirty or bowed track. We pull the sash, replace the rollers with OEM-equivalent hardware, clean and re-tension the track, and re-set the weatherstrip. Full replacement only makes sense if the frame itself is twisted or the track is cracked. Call (682) 281-2168 for a diagnostic and written quote.
Two different problems. Water inside the frame means blocked weep holes or failed gaskets letting fog-driven moisture pool in the vinyl channels. Fogging between the panes means the thermal seal on the insulated glass unit has failed, typically after 10 to 15 years. The first is a clean-and-reseal repair; the second is a glass swap. Call (682) 281-2168 and we’ll diagnose which one you have.
Yes, especially in the Sunset, Richmond, and Mission, where historic design guidelines often require matching recessed depth, trim profile, and visible sash configuration on window replacements. We check setback depth and trim details before we order anything, so the new window sits flush and clears permit review. It’s a site measurement step most contractors skip.
Usually a repair. Sticking Mr-Glass French doors are often a hinge or frame alignment issue from building settlement. Leaking at the sill is typically weatherstrip or threshold wear, especially with ocean-facing salt air. We’ll give you an honest answer after we see the door. Call (682) 281-2168 to schedule an assessment.
Clean the weeps and tracks twice a year, keep weatherstrip and gaskets pliable, and watch for condensation between panes on west- and south-facing elevations. In fog-belt neighborhoods, wiping down vinyl frames monthly helps prevent mildew buildup in the channels.
