Mr-Glass Construction in Foster City, CA | Toolbox Contractors
We provide Home Remodeling in Foster City with independent Mr-Glass service across the area, from window and slider repairs to full replacement and frameless shower glass. What makes our work different here is that we understand how this city’s engineered fill and high water table stress window frames, tracks, and seals in ways you won’t encounter a mile inland. Foster City wasn’t built on solid ground, and Mr-Glass units in these homes need a contractor who knows that. Call (855) 382-3257 for a free estimate.
Toolbox Contractors installs and services Mr-Glass windows, doors, and shower enclosures across Foster City’s Foster-built tracts and bayfront townhome communities. We’re not manufacturer-affiliated or authorized by Mr-Glass. We’re an independent General Contractor in Foster City, which means our loyalty is to the house in front of us, not a factory parts catalog. If your Mr-Glass sliders are dragging, fogging, or leaking, we’ll tell you honestly whether it’s a roller replacement or a full unit swap. Norm Castellano runs the crew, and he’s the one you’ll talk to when you call.
Why Foster City Residents Choose Us for Mr-Glass Service
We know Mr-Glass product lines from the original Series 2000 aluminum sliders put in during the 1960s and 70s to the vinyl single-hung and double-hung replacements common in Foster City’s townhome communities now. That range matters. A 1972 sliding window failing at the sill is a different diagnosis than a 2015 vinyl unit binding in a racked opening. Foster City homes sit on fill over bay mud, and those two conditions often look identical from the outside but need very different fixes. Norm grew up around houses that were always mid-project in the Muscoy area near San Bernardino and learned the trade through San Bernardino Valley College’s construction technology program before spending decades on residential framing, roofing, and full kitchen rebuilds. When a previous contractor has left a mess, he’s the guy who untangles it before real work starts. That same eye for what’s actually wrong applies to every Mr-Glass service call we run in Foster City.
We stock common Mr-Glass rollers, weatherstripping, and hinge hardware locally so most repairs don’t wait on a parts shipment. We use OEM Mr-Glass components where the profile is still supported and the opening is sound. Where OEM is discontinued or priced beyond the value it adds, we’ll tell you that too, and we’ll use quality aftermarket parts instead. You get a straight answer either way.

Common Mr-Glass Construction Problems We Solve in Foster City
- Dragging or stuck aluminum sliders. The Series 2000 aluminum sliders in Foster City’s older tracts collect bay-mud dust and salt air in their tracks. Rollers flat-spot, the sash drags, and eventually the window won’t seat against the weatherstripping. Winter rain-driven wind pushes right past the gap. We clean the track, replace the rollers, and adjust the sash so it closes square again.
- Vinyl sashes that bind and won’t latch. On Foster City’s shallow-water-table lots, minor slab and foundation movement racks rough openings over time. The Mr-Glass vinyl frames themselves look fine, but the sashes bind and latches stop lining up. That’s not a hardware problem. It’s an opening problem, and we fix it by re-squaring and re-shimming the frame rather than forcing the sash.
- Fogged double-pane glass in original 1970s units. Original single-pane Mr-Glass windows in older Foster City homes lose their glazing seals and fog between panes. Once the seal fails, there’s no repair that lasts. We replace the unit, and because many of these homes still have thin original flashing at the sill, we address that while the opening is exposed.
- Corroded shower enclosure hardware near the bay. Foster City’s bayfront humidity and daily fog cycles corrode hinges, pivot pins, and tracking on Mr-Glass frameless shower enclosures faster than inland homes. Panels go stiff, seals pull away from tile, and water escapes. We replace the hardware and re-seal the glass so the enclosure works like it did when it was new.
- Leaking patio and sliding glass doors on the bay side. Mr-Glass sliding door units facing the bay take the worst of winter storms. If the rough opening has shifted even slightly with the fill underneath, the door panel won’t seat and water finds its way under the threshold. We re-flash, re-level, and reset the door so it drains properly.
Mr-Glass Service in Foster City: What Local Conditions Mean for Your Equipment
Foster City is a master-planned city built almost entirely on engineered fill placed over San Francisco Bay tidal flats in the 1960s and 70s. Most lots in the older bayside tracts sit on soft bay mud with a water table just a few feet down. The city’s floodplain rules attach finished-floor elevation and grading requirements to permitted work, and because window and door replacements in older bayside tracts touch the exterior envelope, our Mr-Glass installs here routinely get reviewed against floodplain and geotechnical conditions a crew would never pull in on a same-sized job in San Mateo or Burlingame on solid ground. For you, that means a Mr-Glass window replacement on the bay side isn’t just a sash swap. It often means checking the rough opening for movement, re-flashing against wind-driven rain, and keeping the finished elevation compliant so the permit closes cleanly. In the original Foster-built tracts off Shell Boulevard, we opened up a 1970s home where the Mr-Glass aluminum sliders had been dragging for years and one leaked at every winter storm. The sill flashing was gone and the rough opening had shifted slightly with the fill under the slab. We reset and re-flashed the opening, squared the frame, and installed new vinyl units with fresh weatherstripping and rollers, then came back to hang a Mr-Glass frameless shower enclosure in the hall bath once the tile was dry. The owner’s note afterward was that the bedroom finally stayed dry through a real rain event, not just a drizzle.
Mr-Glass Models & Products We Service in Foster City
We service the Mr-Glass Series 2000 aluminum sliding windows still common in Foster City’s original Foster-built ranches and townhomes. We also handle the Mr-Glass vinyl single-hung and double-hung line now common as a replacement tier for bayfront communities in the 94404 ZIP code. On the shower side, we work on Mr-Glass frameless enclosure hardware sets, including hinges, pivot pins, and seal systems. Mr-Glass sliding glass and patio door units round out what we see most often. Our approach on parts is straightforward: OEM Mr-Glass components where the profile is still supported and the opening is sound, quality aftermarket rollers, weatherstripping, and hinges where OEM is discontinued or overpriced for the value it adds. We keep common parts on hand so most Foster City calls wrap up in one visit. For more on how we work with this product line, see our Mr-Glass sales & service page.

AfterMr-Glass Service Pricing in Foster City
Here’s what Mr-Glass-related work typically runs in Foster City. These ranges are for planning purposes; your exact quote depends on the unit size, condition of the rough opening, and whether floodplain or geotechnical review applies. We provide written line-item estimates before any work starts, so you’ll know exactly what’s included.
| Service | Typical Range |
|---|---|
| Window Replacement | $4500 – $15000 |
| Impact Window Installation | $8000 – $25000 |
| Walk-In Shower Installation | $4500 – $12000 |
| Tub-to-Shower Conversion | $3500 – $10000 |
| Shower Replacement | $3000 – $8500 |
What moves the number on a Foster City job is usually the opening. If the rough opening is square and the flashing is intact, a window swap is straightforward. If the fill has shifted and the sill flashing is compromised, there’s more work to do before the new unit goes in. Our free estimate includes a look at the opening, the existing flashing, and any floodplain considerations that apply to your lot. Call (855) 382-3257 to schedule yours.

FAQs – Mr-Glass Construction in Foster City
Yes, and more often than most homeowners expect. Foster City’s floodplain regulations attach finished-floor elevation and grading requirements to permitted work, and exterior envelope work like window replacement on older bayside tracts triggers review that wouldn’t apply in San Mateo or Burlingame on solid ground. Shower enclosure work rarely does, but a bay-side window or slider usually will. We handle the permit path for you and make sure the finished elevation stays compliant. Call (855) 382-3257 and we’ll walk you through what applies to your specific lot.
The track is rarely the problem on a Foster City slider. What’s usually happened is the rough opening has shifted slightly with the fill under the slab, or the rollers have flat-spotted from years of bay-mud grit in the track. Clean tracks help, but if the frame is no longer square, the sash will drag no matter how much you vacuum the channel. We check the opening first, then decide whether it’s a roller replacement or a frame re-square.
For Foster City’s bayfront and lagoon-side homes, yes, and it happens faster than inland. Daily fog cycles and salt air corrode the hinge pins and pivot hardware on Mr-Glass frameless enclosures, and the temperature swings make the seals pull away from the tile. We replace the corroded hardware and re-seal the glass so the enclosure runs smoothly and stays watertight. Call (855) 382-3257 for an exact quote, free estimates included.
Not exactly. The Series 2000 aluminum sliders installed in many Foster City homes from that era are discontinued as a full line. We can often match the opening dimensions and trim profile with a current vinyl unit that fits cleanly, and if a full replacement is overkill, we can rebuild the existing sash with new rollers and weatherstripping. What we won’t do is put a mismatched aftermarket frame in an opening and call it good. We’ll tell you what’s available and what’s the better long-run decision.
Most of the time, yes. In Foster City’s older bayside tracts, we routinely find the original sill flashing is thin, compromised, or missing entirely under the stucco. Wind-driven winter rain finds those gaps fast. We replace the flashing and re-seal the opening while the old unit is out, which is the main thing that stops a new window from leaking like the old one did. It adds a bit to the job, and it’s the difference between a dry bedroom and another rainy-season call. Call (855) 382-3257 for a free estimate that includes the flashing scope.
