AfterMr-Glass Construction in San Francisco, CA | Penhallow Remodeling
We provide independent Mr-Glass window, patio door, and glass enclosure service across San Francisco, from the fog-belt avenues of the Sunset to the Victorian flats of the Mission. What makes our Mr-Glass work different here comes down to one thing: we’ve spent years watching how these units actually perform against marine fog, old balloon-frame openings, and a building-code gauntlet that doesn’t exist at this scale anywhere else in the Bay Area. If you’ve got a fogged IGU, a dragging 800 Series slider, or a leaking shower enclosure, call us at (936) 259-2607 for a straight answer and a written price before any work starts.
Why San Francisco Residents Choose Us for Mr-Glass Service
Trevor Nash started Penhallow because he was tired of watching homeowners get handed vague estimates and vaguer timelines. So we do things differently. We check the unit, name the failure, and put a written number in front of you before we pick up a tool. “Give me the whole picture first, then we pick up the tools.” That’s the standard we run every Mr-Glass job by, whether it’s a single fogged sash in Noe Valley or a full patio door rebuild in the Western Addition.
We’re an independent contractor. We are not affiliated with, endorsed by, or authorized by Mr-Glass, and we make no warranty claims on the manufacturer’s behalf. We source genuine Mr-Glass replacement IGUs, rollers, locks, and hardware where they’re still available, and use dimensionally matched aftermarket glass and seals when the OEM part is discontinued or the lead time would leave your opening exposed to San Francisco weather. We’ll tell you honestly when a fogged sash is worth repairing versus when replacement is the better long-term spend. We don’t sell replacement glass on a unit that only needs a $40 roller and realignment.
Common Mr-Glass Construction Problems We Solve in San Francisco
- Fogged dual-pane IGUs from seal failure. A failed perimeter seal lets moisture into the airspace between the panes, and once that starts, the glass won’t clear on its own. We see this accelerate in the Sunset and Richmond, where persistent marine fog and constant temperature swings push moisture past aging seals on Mr-Glass 400 Series sashes that might have lasted years longer in a drier climate.
- Wood-rot and moisture staining at window and patio-door frames. Many Mr-Glass units were installed into original 1895 – 1915 balloon-frame openings in the Mission, Castro, and Haight-Ashbury. Fog-driven infiltration finds its way behind exterior trim and into the rough opening, and by the time staining shows on interior casing, the subframe is often further gone than it looks.
- Sliding patio door track wear and roller failure on the 800 Series. Windblown grit and debris collect in the sill channel, especially on west-facing openings that catch the afternoon wind off the Pacific. Rollers wear flat, the door drags, and eventually the panel jumps the track. The fix is usually new rollers and a track cleanout, not a whole door.
- Leaking or failed glass-to-frame seals on shower enclosures. San Francisco bathrooms with weak ventilation and high marine humidity keep surfaces wet longer than they should. On Mr-Glass frameless and semi-frameless enclosures, that means the glass-to-frame gaskets and hardware corrode faster, and the weep paths clog with mineral buildup.
- Fogged glass on shower enclosures. Constant humidity and hard water accelerate glass etching and seal breakdown. We replace IGUs and re-seal enclosures, and we’ll tell you if the problem is the seal or simply dissolved minerals that need professional restoration.
Mr-Glass Service in San Francisco: What Local Conditions Mean for Your Equipment
San Francisco’s Mandatory Soft-Story Retrofit Program (Building Code Chapter 4D) changes how we approach Mr-Glass window and door work in ways that simply don’t apply in Oakland or San Jose. Thousands of wood-frame apartment buildings with open ground-floor garages or commercial space are on city-enforced deadlines to complete seismic structural upgrades, and any window or door opening we touch on one of those buildings has to coordinate with the structural contractor’s cripple-wall bracing, foundation bolting, and DBI inspection schedule. On a soft-story retrofit in the Western Addition, our crew had to coordinate Mr-Glass 400 Series window replacement with our General Contractor in San Francisco on cripple-wall bracing and foundation bolting so the new openings landed on the reinforced framing. A homeowner’s fogged 400 Series IGUs were replaced with matched units while we adjusted the reveal tolerances to the retrofit work, and we re-flashed the openings against the building’s original plaster returns. The result was a sealed, correctly seated window set that passed DBI inspection without re-cutting the finished wall. If you own a wood-frame building in the city with open ground-floor space, your Mr-Glass openings are not standalone repairs. They’re part of a structural process, and we plan the work accordingly.
Mr-Glass Models & Products We Service in San Francisco
We work on the Mr-Glass 400 Series vinyl single-hung and sliding windows, the 800 Series vinyl patio door and multi-slide systems, frameless and semi-frameless shower enclosure kits, and custom glass and mirror products. For San Francisco turnaround, we stock common Mr-Glass roller sets, locks, and replacement seals locally so a dragging patio door in the Richmond doesn’t wait two weeks on a parts shipment. When the OEM part is discontinued, we use dimensionally matched high-quality aftermarket glass and seals rather than leaving a unit open to the fog while a backorder drifts. Our page on Mr-Glass sales & service covers the full scope, but here’s what matters for San Francisco: we know which of these units fail most often in marine-fog conditions and which ones hold up.
Mr-Glass Service Pricing in San Francisco
These are the ranges you should plan around when pricing Mr-Glass work with us. The final number depends on the unit count, the condition of the rough opening, whether the building is under a soft-story mandate, and whether we’re repairing an existing unit or installing new.
| Service | Typical Price Range |
|---|---|
| Window Replacement (Mr-Glass units) | $5,310 – $17,700 |
| Impact Window Installation | $9,440 – $29,500 |
| Walk-In Shower Installation / Frameless Enclosure | $5,310 – $14,160 |
Every estimate is written, line-itemed, and free. The number on the written estimate is the number on the invoice. If a fogged IGU needs replacement and nothing else is wrong, we’ll quote the IGU and not a whole window. Call (936) 259-2607 to schedule a free estimate at your San Francisco property.

FAQs – Mr-Glass Construction in San Francisco
Yes, in most cases we can replace the IGU, the insulated glass unit, without pulling the entire frame. We do this regularly on Mr-Glass 400 Series sashes where the frame and operation are still sound. We’ll tell you if the frame, balances, or weatherstripping are too far gone and replacement makes more sense. Call (936) 259-2607 and we’ll look at the specific unit before recommending anything.
Usually not. On the 800 Series, a dragging door is typically worn rollers or a grit-packed track, not a failed door. We clean out the sill channel, replace the rollers, and realign the panel, and the door runs like it should. If the track itself is bent or the frame has rot from fog-driven moisture, then we’ll give you an honest replacement number. Call (936) 259-2607 for a free in-person look.
It can. If your building is on the Chapter 4D mandatory retrofit list, any window or door opening we work on needs to coordinate with the structural contractor’s bracing and bolting schedule and DBI inspection. We’ve done this coordination on Mr-Glass 400 Series replacements in the Western Addition, and we plan the sequence so your glass work doesn’t delay the retrofit or force re-cutting a finished wall.
Marine fog means constant moisture against the exterior glass, and when the perimeter seal on a dual-pane IGU fails, that moisture works its way into the airspace and fogs from the inside. The Sunset and Richmond get more of this than inland cities because the fog sits on those neighborhoods for much of the year. A failed IGU won’t clear on its own. Call (936) 259-2607 to get an exact quote on replacement glass – estimates are free.
Replacing glass in an existing enclosure usually falls under a minor repair, but any change to the plumbing, drain, or waterproofing behind the tile requires a permit through the DBI. For full Bathroom Remodeling - San Francisco projects, we handle all required permits and inspections. We pull the permit when it’s required and handle the inspection, so you’re not left with an open permit. Call (936) 259-2607 and we’ll tell you up front whether your enclosure job needs one.
