From the people who buy from us

Fabricators and builders, in their own words.

"Cristian's team holds slabs for us without a deposit when we trust them with a job. That has saved us at least three closings this year. They run their yard like they're part of our shop."
Daniel R.Owner, Sierra Stone Fabrication, Rocklin, CA
"We do about 40 multifamily units a quarter and JMP is the only supplier in the region who calls us when a quartz dye lot ships short. That heads-up is worth a lot."
Priya M.Project Manager, Westhaven Builders, Folsom, CA
"I send my designers to walk the yard before they finalize a selection. Cristian doesn't upsell — he points them at the slab that fits the budget and the use. Rare."
Mark T.Principal Designer, Oak & Iron Studio, Sacramento, CA
"Delivery shows up when they say it will. After ten years in the trade I'd rank that the single most underrated thing a slab yard can offer."
Antonio G.Lead Fabricator, Valley Granite Co., Roseville, CA

Common questions

What trade partners ask first.

Read the full FAQ →
Is JMP Stone Supply open to the public?+

No — we are a trade-only wholesale yard. We sell to licensed fabricators, contractors, kitchen and bath dealers, builders, and the design trade. If you are a homeowner, ask your fabricator to walk the yard with you.

What do I need to open a trade account?+

A California resale certificate, a current CSLB license number (or design-trade equivalent), and a W-9. Paperwork takes about a business day to process once we have everything.

Do you offer net-30 terms?+

Yes, after a credit application is approved. First three orders are typically prepaid while we set up references. Most accounts move to net-30 within 60 days.

What is your minimum order?+

There is no slab minimum. Remnants are sold by the piece. Drop-ship from manufacturer partners has a one-slab minimum and a freight fee unless combined with a regular delivery.

Where do you deliver?+

Our flat-fee delivery zone covers Sacramento, Roseville, Folsom, Auburn, Rocklin, Lincoln, Loomis, El Dorado Hills, and Granite Bay. We deliver to the Bay Area, Reno, and the Central Valley with a quoted freight charge.

How do slab reservations work?+

A trade-account holder can place a 7-day hold by email or phone. After 7 days the hold expires unless renewed. We do not double-book a tagged slab.
