Mr-Glass Construction in Highgrove, CA | Timberline Contractors
We service and install Mr-Glass frameless shower enclosures, sliding doors, and glass products across Highgrove, CA. The thing that separates our Highgrove work from everywhere else is the permitting reality: every enclosure we install here goes through Riverside County’s building department, not a city hall. If you’re dealing with a failing Mr-Glass door or planning a new walk-in shower in the 92313 ZIP code, call (866) 253-5808 for a free estimate.
Timberline Contractors is an independent Mr-Glass service provider, not a manufacturer-authorized dealer. That independence means we’re free to recommend the repair that actually fits your enclosure rather than the replacement that fits a sales quota. We’ve worked on enough Mr-Glass units across Highgrove’s mid-century homes and ranch properties to know exactly where the hardware fails under this basin’s heat and wind cycles, and we bring that same expertise to our Colton Mr-Glass service.
Why Highgrove Residents Choose Us for Mr-Glass Service
We stock the specific Mr-Glass hinges, seals, clamps, and rollers these enclosures use, and our crews know the failure patterns that show up in Highgrove more than anywhere else we work. Seasonal wood movement in older wall framing strips pivot screws. Private-well water chemistry pits the clamps. Santa Ana dust fouls the tracks on ranch properties.
Nelson Fung grew up watching his grandfather debate tile prices in Chinatown and later learned the trade at Los Angeles Trade-Technical College before spending years on remodels across the LA basin. That background shapes how we approach every Mr-Glass job: measure the framing, check the permit history, then do the work so the glass stays square through the next heat wave. If you want someone who will explain why the substrate matters more than the finish on top of it, that’s us.

Common Mr-Glass Construction Problems We Solve in Highgrove
- Stripped pivot and hinge screws in older wall framing. Highgrove’s summer heat expands and contracts the stud walls in mid-century homes, and the pivot screws on Mr-Glass frameless doors gradually lose their bite. We reframe the hinge points with solid blocking rather than re-driving the same screw into spalled wood.
- Dry-cracked factory seals and sweeps. Intense heat plus the basin’s dryness causes the original Mr-Glass seals to shrink and split, letting water wick into drywall near the curb. We replace them with OEM-spec seal kits and verify the curb waterproofing before re-hanging the glass.
- Corroded glass-to-metal clamps on private wells. Hard-water mineral buildup from Highgrove wells pits and corrodes the finish on Mr-Glass clamps and brackets. We swap in corrosion-resistant replacements that match the original load specs.
- Binding or derailed sliding-door rollers. Santa Ana wind events blanket ranch properties with dust, and that grit works into the roller tracks on Mr-Glass sliding doors. We clean, re-lubricate, and replace rollers so the door glides instead of grinding.
- Non-permitted additions discovered mid-project. We routinely find that a previous owner’s bathroom addition was never pulled through Riverside County. That changes the scope of a Mr-Glass enclosure install and we handle the county records research before we touch the framing.
Mr-Glass Service in Highgrove: What Local Conditions Mean for Your Equipment
Here’s the thing most contractors won’t tell you until they’re already on the clock: Highgrove is unincorporated Riverside County. That means every Mr-Glass shower enclosure or kitchen glass project we permit goes through the county building department on Gateway Drive, not a city counter. It also means a lot of the older bathrooms in Highgrove were built or expanded without ever seeing a county inspector. We pull county records on title before we start any enclosure work, because discovering an unpermitted addition after you’ve hung a frameless door is the kind of discovery that turns a two-day job into a six-week correction.
On a ranch property off the Box Springs foothills, our crew replaced a failing Mr-Glass frameless enclosure where the original pivot hinge had stripped out of a mid-century stud wall and the sweep seal was letting water wick into the adjacent drywall. We reframed the hinge points, installed a new OEM-spec hinge set and seal kit, and added a proper curb waterproofing detail before re-hanging the glass. The homeowner avoided a full tear-out, and the enclosure now operates smoothly despite the seasonal heat swings.
Mr-Glass Models & Products We Service in Highgrove
We work on the full Mr-Glass lineup: the Frameless Shower Door series in both hinged and pivot configurations, the Sliding Shower Door series, Custom Glass Shower Enclosures, and Mr-Glass Mirror & Glass products. Our parts approach is straightforward. We use OEM Mr-Glass replacement hinges, seals, and rollers where available to preserve the original fit and finish. When a part has been discontinued, we source aftermarket equivalents that meet the same load and corrosion specifications rather than improvising with whatever’s on the truck. If the glass itself is chipped or the frame is bent beyond safe adjustment, we’ll tell you replacement makes more sense than patching a failing enclosure.
Highgrove jobs don’t stall waiting on parts. We keep the common Mr-Glass hinge sets, seal kits, and roller assemblies stocked locally, and we’re familiar with the Mr-Glass sales & service needs that come up repeatedly in this climate.

AfterMr-Glass Service Pricing in Highgrove
What you’ll pay for Mr-Glass service in Highgrove depends on the scope: a hinge-and-seal repair runs far less than a full custom enclosure, while a tub-to-shower conversion that requires reframing and new glass falls into a higher bracket. Our written estimates are line-item and fixed, so the number we quote is the number you approve.
| Service | Typical Range |
|---|---|
| Frameless Glass Shower Enclosure | $4,500 – $12,000 |
| Walk-In Shower Installation | $4,500 – $12,000 |
| Tub-to-Shower Conversion | $3,500 – $10,000 |
| Bathroom Remodel | $9,000 – $28,000 |
Every estimate includes a permit review through Riverside County, a check of the existing framing, and a straight answer about whether repair or replacement is the better spend. Call (866) 253-5808 for an exact quote on your Mr-Glass project.

FAQs – Mr-Glass Construction in Highgrove
Yes, in most cases. Because Highgrove is unincorporated, any project that alters plumbing or framing requires a Riverside County building permit, and that includes converting a tub to a shower or adding a new walk-in enclosure that changes the drain configuration. We pull the permit, schedule the inspection, and confirm the county signs off before we call the project complete. Call (866) 253-5808 and we’ll check your specific scope.
Usually the pivot screws are stripping out of old framing. Highgrove’s hot summers expand and contract the wood, and after enough cycles the screws lose purchase. We fix it by opening the wall and installing solid blocking at the hinge points rather than re-driving screws into compromised studs.
If the glass is sound and the frame is still square, yes. We replace OEM-spec seals, sweeps, and hinges as a targeted repair. We only recommend full replacement when the glass is chipped or the frame is bent beyond safe adjustment.
It does. Well water in this area often carries high mineral content that leaves deposits on glass and corrodes clamps and brackets over time. We can recommend glass treatments and replace corroded hardware with corrosion-resistant components. Call (866) 253-5808 if you’re seeing pitting on your hardware.
We pull the Riverside County records before we start. If the addition was never permitted, we’ll tell you exactly what it takes to bring it up to code so your new Mr-Glass enclosure doesn’t get flagged at inspection.
