Mr-Glass Construction in Hillsborough, CA | Ashford Contractors
We install, repair, and replace Mr-Glass shower enclosures and glass systems across Hillsborough, CA, as a trusted General Contractor in Hillsborough. The work here runs different than anywhere else on the Peninsula because Hillsborough’s older custom homes rarely have square walls, and the town’s architecture review and tree-protection rules often force a glass project to be re-measured after framing actually goes in, not from the drawing. That’s the thing most glass contractors learn the hard way in Hillsborough. We learned it fifteen years ago, and our whole approach is built around it. Call (877) 752-3868 for a free estimate on Mr-Glass framing, templating, hinge repair, or panel replacement.
Why Hillsborough Residents Choose Us for Mr-Glass Service
We’re not a Mr-Glass dealer. We’re an independent general contractor that installs and services Mr-Glass in Burlingame and across the Peninsula, so our estimators work directly from the manufacturer’s fabrication specs rather than a dealer network. That matters when a frameless unit is templated wrong or a hinge fails: we diagnose and re-fit it in the field instead of pushing a whole new enclosure. For Hillsborough homeowners, that independence means the fix we recommend is the fix you actually need, not the one with the highest markup.
Our owner, Glen Mossier, grew up in Foster City’s Marlin Cove and trained in construction technology at Skyline College. He’s spent two decades on Mr-Glass service in San Mateo County remodels, and he’ll tell you the same thing he tells our crews: build it right the first time, and you won’t be rebuilding it in ten years. That philosophy shows up in every Mr-Glass template we take, every hinge we reset, and every caulk line we lay along a Hillsborough curb.
We keep OEM Mr-Glass hinges, pivots, sweeps, and seals stocked for the enclosure lines most common in Hillsborough homes, which means faster turnaround without waiting on a distributor shipment.

Common Mr-Glass Construction Problems We Solve in Hillsborough
- Out-of-plumb templates on mid-century bathrooms. Hillsborough’s older custom homes rarely have square walls. A field measure taken on a racked wall from a 1950s or 1960s bath yields an enclosure that won’t close cleanly on the hinge side. We template to the actual framed opening, not the drawing, and adjust pivot placement accordingly.
- Hinge and pivot fatigue on heavy frameless doors. Heavier 3/8-inch frameless doors on sloped-ceiling or non-standard opening baths sag at the pivot over time, causing sweep-seal drag and water escape. Hillsborough has no shortage of sloped ceilings and custom door openings, so we see this failure mode constantly and repair it with OEM pivots rated for the actual panel weight.
- Seal and caulk failure at the curb. Winter rains plus slab or curb movement on clay-heavy Peninsula soils break the silicone line, letting water wick under the track. We see this across Hillsborough’s wooded lots, where soil expands and contracts with the rainy season. We re-caulk with a slope-correct bead so runoff actually sheds back to the drain.
- Coating and hard-water haze on fixed panels. Unsealed or worn factory coatings on Mr-Glass panels in high-mineral water leave mineral etching that looks like permanent clouding. Once the coating is compromised, the glass itself gets attacked. We’ll replace the panel when that happens and talk through coating options that hold up to Peninsula water chemistry.
- Re-scoped openings after tree-protection review. Root-zone protection rules in Hillsborough can limit where a plumbing wall or curb moves, which changes the rough-in dimensions after architectural review is already done. Glass templated before that re-scope is wrong the day it’s cut. We template after the actual rough-in, every time.
Mr-Glass Service in Hillsborough: What Local Conditions Mean for Your Equipment
Here’s the thing nobody outside Hillsborough understands: the town’s design-review and tree-protection rules mean a bath or glass project can clear architectural review and still be re-scoped at framing, because root-zone protection on wooded lots often limits where a plumbing wall or curb can move. A homeowner gets approval for a curb shift, then the arborist comes back and flags a mature oak, and suddenly the curb stays put or moves two inches the other way. Now the opening width is different, the door swing is different, and any glass templated from the original drawing no longer fits.
We’ve pulled off Mr-Glass repair in Highlands-Baywood Park and Hillsborough enclosures where the glass was cut to a plan that didn’t survive contact with the actual rough-in. On a mid-century ranch off Crystal Springs Road, our crew took over a bathroom where the original Mr-Glass frameless hinged enclosure had been templated to the drawing rather than the framed opening, and the door dragged on a racked wall. We re-measured against the plumb line, reset the pivot hinge, switched to a 3/8-inch fixed panel with an OEM sweep, and re-caulked the curb with a slope-correct bead so winter runoff shed back to the drain instead of under the track. That’s the difference between glass that works in Hillsborough and glass that works on paper.
Mr-Glass Models & Products We Service in Hillsborough
We install and service the Mr-Glass frameless hinged shower enclosure in the Gen series, the semi-frameless sliding tub-shower enclosure, the Neo-Angle corner shower enclosure, and custom-cut Mr-Glass glass panels and mirrors. For enclosures we service, we source OEM hinges, pivots, sweeps, and seals so the fit and load rating stay correct. We’ll substitute quality aftermarket hardware only when an OEM part is discontinued and no equivalent remains available through the manufacturer’s parts channel. Replacing seals, hinges, or a single glass panel is almost always the right call before considering a full enclosure replacement, and that stance is what keeps our Hillsborough repair bills lower than a full re-enclosure would run. For our full brand line and parts approach, see our Mr-Glass sales & service page.

AfterMr-Glass Service Pricing in Hillsborough
Here’s what Mr-Glass glass and shower enclosure work typically costs in Hillsborough. These figures reflect the local market and the labor realities of working on racked walls, clay soils, and tree-protected lots.
| Service | Price Range |
|---|---|
| Walk-In Shower Installation | $4,500 – $12,000 |
| Shower Replacement | $3,000 – $8,500 |
| Tub-to-Shower Conversion | $3,500 – $10,000 |
| Bathroom Vanity Installation | $800 – $3,000 |
The biggest cost driver in Hillsborough is template accuracy. A shower replacement on a square, modern opening moves fast. Same job on a 1968 custom with racked walls and a curb that can’t move because of a heritage oak takes longer to measure, shim, and fit, and that’s honestly where the spread in those ranges comes from. Curious where your project lands? Call (877) 752-3868 and we’ll walk through it with you.

FAQs – Mr-Glass Construction in Hillsborough
No, and we won’t. In Hillsborough, tree-protection and architectural review can shift a plumbing wall or curb after the drawings are approved, so we template only after the actual rough-in framing is done and verified. If you’re mid-remodel and want to get glass on the schedule, call (877) 752-3868 and we’ll time the template for the day the rough-in passes inspection.
Usually a hinge fix. Sagging frameless doors in Hillsborough are typically from pivot fatigue on heavier 3/8-inch panels, not from anything wrong with the glass itself. We reset or replace the OEM hinge and pivot, adjust the sweep, and the door closes cleanly again. A full replacement only pencils out when the panel is etched or cracked.
It can. Root-zone protection on wooded lots sometimes limits where a curb or plumbing wall can move, which changes the rough-in opening after the architectural review is already done. That’s why we don’t template off approved drawings alone. We measure against what actually got framed. Call (877) 752-3868 before you finalize your glass order.
Clay-heavy Peninsula soils expand with winter rains, and that movement transfers to the slab or curb under your enclosure. The silicone line breaks, then water wicks under the track. We re-bed the curb with a slope-correct bead and use a sealant that flexes more than what was originally applied. Want it fixed before the next storm cycle? Call (877) 752-3868 for a free estimate.
Yes. We replace single Mr-Glass glass panels, sweeps, seals, hinges, and pivots on existing enclosures. If the panel is custom-cut, we match the original fabrication dimensions and glass thickness from Mr-Glass’s spec sheet. Replacing one panel or the seals is far less money than a full enclosure, and we’ll always tell you when that’s the right move.
