Terms & Conditions
Last reviewed 14 February 2026.
These terms apply when you visit the studio, browse this site, request a quotation, place a material order, or engage Datumly for installation work. They are designed to be read once, set expectations clearly, and be referred back to in the rare event something needs to be sorted out.
1. Who we are
"Datumly", "we", "us", and "our" refer to Datumly Tile & Stone Solutions LLC, registered in California (registration BCN-2019-447821), with its principal office at 248 Madrone Boulevard, Suite 14, San Mateo, CA 94403.
2. Studio sessions
A 90-minute studio session is paid at the time of booking and credited in full against any subsequent material order over $2,000 placed within 12 months. Cancellations made with 24 hours' notice are refunded; same-day cancellations are not, except in genuine emergency.
The written specification produced by a studio session belongs to you. You are free to use it with another supplier; we'd prefer to know if you do, simply so we can close the file.
3. Material orders
Orders are confirmed in writing, with a deposit of 50% of the material total payable to release the order to the mill. The balance is due on delivery to our warehouse, before scheduled despatch to your site or to your collection.
Lead times quoted at order are estimates based on current mill information. We pass on substantial changes (more than two weeks beyond the quoted estimate) within five working days of being notified ourselves.
4. Custom and made-to-order items
Custom-finished or cut-to-pattern items, including milled wood floors, custom vanities, and waterjet stone, are non-cancellable once production has begun. We confirm the order in writing immediately before that point and ask you to sign off the production drawing.
5. Installation engagements
Installation is undertaken under a separate written contract drawn for each project, including a method statement, a fixed-fee or time-and-materials quotation, a payment schedule, and a defined scope. The contract takes precedence over these general terms where they differ.
We carry general-liability and worker's-compensation insurance; certificates are available on request.
6. Variations and changes
Changes to a confirmed order or a confirmed installation scope are documented as a written variation, signed by both parties before work proceeds. Verbal variations are not binding on either side; the rule protects you as much as us.
7. Warranties
Material warranties are passed through from the mill or manufacturer. We make these terms available before order. Installation work is warranted by Datumly for two years from completion against defects in workmanship; routine wear, accidental damage, and movement caused by structural change to the property are not covered.
8. Liability
Our liability for any claim arising from a material order is limited to the price paid for the material in question, plus the cost of removing and replacing it where we performed the original installation. We do not accept liability for indirect or consequential losses.
Nothing in these terms limits liability for personal injury caused by negligence, for fraud, or for any other liability that cannot lawfully be limited.
9. Governing law
These terms are governed by the laws of the State of California. Disputes that cannot be resolved by direct conversation will be referred to mediation before any court action; the courts of San Mateo County have non-exclusive jurisdiction.
10. Changes to these terms
We update these terms from time to time. The version published on the site at the date of an order or contract applies to that engagement; subsequent changes do not retroactively alter your existing agreement with us.
