Mr-Glass Construction in San Francisco, CA | Toolbox Contractors
We provide independent Mr-Glass window, door, and storefront installation and repair across San Francisco, from Noe Valley Victorians to SoMa commercial spaces. We’re not a Mr-Glass authorized dealer or manufacturer affiliate, but our crews have serviced these products long enough to know their failure points, their quirks, and what it takes to make them last in a city where salt air and 1920s framing both work against you. If you’re dealing with a fogged Mr-Glass 400 Series panel or a sliding door that’s gone stiff, call us at (855) 382-3257 and we’ll tell you straight whether it’s a repair or a replacement.
Why San Francisco Residents Choose Us for Mr-Glass Service
Most window contractors in San Francisco know glass. Fewer know Mr-Glass specifically. The difference matters when you’re trying to match an existing Mr-Glass 200 Series double-hung in a 1910 Edwardian or source rollers for a Mr-Glass Sliding Glass Door that was installed before the dot-com boom. We stock common Mr-Glass hardware locally, which means less waiting on freight from a distributor, and we source OEM parts for critical components like weatherstripping and locks when they’re available. Norm Castellano, our owner, grew up around half-finished houses in the Muscoy area and learned construction the hard way before running crews across the Inland Empire and now the Bay. He’s the first to admit when an old frame is still better than anything new on the market. That honesty carries into how we quote Mr-Glass work.

Common Mr-Glass Construction Problems We Solve in San Francisco
- Fogged dual-pane units from marine humidity. The fog belt that rolls through the Sunset and Richmond districts doesn’t just chill the air, it pushes moisture into any compromised seal. Mr-Glass dual-pane units that lose their desiccant show condensation between the panes within months of that first pinhole breach. We replace the insulated glass unit, not the whole frame, whenever the sash is sound.
- Corroded aluminum frames from salt-laden air. Homes within a mile of Ocean Beach or the Bay see aluminum Mr-Glass frames pit and oxidize years faster than inland units. We see this constantly in the Outer Sunset and Marina District. The fix usually involves stripping corroded hardware, treating the frame, and replacing rollers or hinges that have seized.
- Water infiltration at sills and jambs on older installations. A lot of Mr-Glass windows in San Francisco were put in during the 80s and 90s when flashing standards were looser. Add 30 years of wind-driven rain against a west-facing wall and you get rot at the sill. We don’t just swap the window; we open the rough opening, repair framing, and install proper flashing before the new unit goes in.
- Sliding door hardware failure from damp conditions. Mr-Glass Sliding Glass Doors are common in the ground-floor units and rear additions typical of San Francisco’s soft-story buildings. When rollers corrode or the track accumulates debris from a hillside property, the door goes heavy, then binds, then stops. We replace rollers and tracks more often than full doors.
- Storefront system wear in high-traffic commercial entries. Mr-Glass Storefront Systems take a beating in busy corridors like Mission Street. Constant foot traffic, damp air, and occasional impacts stress the hinges and weatherstripping. We handle commercial service calls that most residential window companies won’t touch.
Mr-Glass Service in San Francisco: What Local Conditions Mean for Your Equipment
There’s one thing about working in San Francisco that shapes every Mr-Glass project here more than any other factor: the city’s historic preservation review. Any exterior alteration to a building 45 years or older, including window and door replacement, can trigger a Planning Department review and a Historic Resource evaluation. In neighborhoods like the Mission, Pacific Heights, and Noe Valley, that’s not a rare edge case. It’s the default. What it means for a Mr-Glass owner is that you can’t always swap a wood-sash window for an aluminum-frame Mr-Glass unit and call it done. The city may require specific window profiles, sightlines, or even full wood replacement to match the original character. We’ve navigated enough of these reviews to know what flies and what stalls. Sometimes the Mr-Glass product works. Sometimes it doesn’t. We’ll tell you before you buy, not after the permit gets rejected.
Mr-Glass Models & Products We Service in San Francisco
Our crews work on the full Mr-Glass lineup you’ll find across San Francisco’s housing stock. That includes the Mr-Glass 400 Series, the more budget-conscious Mr-Glass 200 Series, Mr-Glass Sliding Glass Doors, and Mr-Glass Storefront Systems in commercial storefronts along corridors like Valencia Street and Geary Boulevard. For windows and doors, we carry common rollers, hinges, locks, and weatherstripping so a same-week repair doesn’t turn into a six-week waiting game. When a critical part is no longer made, we source high-quality aftermarket replacements that match the original dimensions. For full replacements, we quote the unit, the install, and the permit path as one package. See our Mr-Glass sales & service page for the full scope of what we handle.

AfterMr-Glass Service Pricing in San Francisco
In San Francisco, expect to pay slightly more than the regional average because permit review and hillside access both add labor. But the numbers below are what we quote, not a teaser.
| Service | Typical Range |
|---|---|
| Window Replacement | $5,310 – $17,700 |
| Impact Window Installation | $9,440 – $29,500 |
What drives the spread is frame condition, historic review requirements, glass type, and how many units you’re replacing at once. A single Mr-Glass 200 Series replacement in a mid-century apartment is the low end. A full Mr-Glass 400 Series swap across a three-story Edwardian with Planning review lands at the top. Our free estimate includes a site visit, a written line-item quote, and a straight answer on whether repair is smarter than replacement. Call (855) 382-3257 to schedule one.

FAQs – Mr-Glass Construction in San Francisco
Yes, in most cases. San Francisco requires a building permit for window replacement when the opening changes, and on buildings 45 or older, a Historic Resource evaluation may also apply. We handle the DBI permit paperwork as part of the job, and we’ve learned which window profiles pass historic review in neighborhoods like Noe Valley and Pacific Heights. Call (855) 382-3257 and we’ll tell you what your specific building triggers.
The marine fog belt keeps exterior surfaces damp for weeks at a time, which corrodes aluminum frames and hardware exposed to salt air near the coast. It also finds any gap in a dual-pane seal and starts the fogging process. Mr-Glass units installed within a mile of the ocean typically need hardware replacement two to three times more often than inland units. If you’re seeing condensation between panes, call us before the sash itself deteriorates.
Usually we can repair it. We replace rollers, tracks, locks, and weatherstripping on Mr-Glass Sliding Glass Doors all over San Francisco. If the frame is bent, the glass is cracked, or the door has been out of square like the Noe Valley Edwardian we rebuilt, replacement becomes the honest call. We’ll tell you which one saves you money over the next ten years.
Custom Mr-Glass units typically take four to eight weeks from order to delivery. Add two to six weeks if your building requires Historic Resource review before a permit will issue. We start the permit process the same week we measure, so the review and the manufacturing run in parallel when possible. That’s how we keep a full wait from stretching into half a year.
Sometimes. The Mr-Glass 400 Series and 200 Series work well in many mid-century and later buildings, but on a 1900s Victorian in the Mission or a 1920s Edwardian in Visitacion Valley, the city’s preservation standards often demand wood windows with matching sightlines instead. We’ll review your property’s historic status before recommending Mr-Glass, so you don’t spend months waiting for approval that won’t come. Call (855) 382-3257 for a straight read on your building.
