Buying and pricing
How is rock sold?
Nearly all of our stone arrives on pallets and is sold by weight. A Weighmaster records the weight of your purchase less the pallet. See how rock is sold.
Why don't you publish prices?
Prices can change over short periods. Freight is the biggest variable, with diesel costs, and quarries adjust prices as the vein of stone changes. Call or visit for a current quote.
Where does your stone come from?
California, Arizona, Utah, Mexico and across the USA.
Why is a stone sometimes out of stock?
Many quarries lose access in heavy rain, sometimes all winter, and multi-ton orders can use up what is on hand. Call to check what is in the yard today.
I have a big job. How do I make sure the stone matches?
Talk to us about the whole job up front so we can plan quantities and matching stone before you start.
Can you order a stone you do not carry?
Often, yes. Ask about a custom or special order.
Flagstone
What is the difference between Select and patio flagstone?
Select is stand-up flagstone in large pieces of about 4 to 12 square feet, often in several thicknesses. Patio flagstone lies flat, in pieces from about 8 inches to 4 square feet.
What is 1 1/4 inch Select used for?
Large patios. It is cut close to 1.25 inches thick and should be hard-set with mortar over concrete.
Which thickness can I soft-set on sand?
1 1/2 to 2 inch flagstone. It does not need a hard set, so you can lay it on sand and decomposed granite. See the flagstone thickness guide.
What is veneer?
Thin-cut stone, called 1 1/4 minus because it is no thicker than 1.25 inches. It should be hard-set with mortar over concrete.
Can I save money by spacing flagstones farther apart?
Yes, wider joints with more decomposed granite use less stone. Consider foot traffic, because high heels can slip into wide joints.
Do I have to use one stone for the whole job?
No. Different stones can complement each other. We will suggest what works and what we would not recommend.

Installing and sealing
Should I choose a soft base or a hard base?
A hard base is mortared and permanent. A soft base is set loosely and lets water through. You cannot pressure-wash sand or DG joints, and if you want moss between stones you need a soft base. See soft-set vs hard-set.
How do I prepare stone for sealing?
Never seal wet stone. Wash the area to remove dust, let it dry 5 to 10 days, and turn off sprinklers that reach it.
How do I apply sealer?
Brush, roll or spray it in the early morning, not in the heat of the day. Apply two coats, first north to south and then east to west, for even coverage.
Can I get the wet look on dry stone?
Yes. Some sealers give stone its wet color. Sealers come in shiny and matte finishes, and the stone's porosity changes the result. See wet look vs natural.
How do I install Gator Dust?
It needs a gravel base 2 to 3 inches thick, and Anna recommends 1 inch of sand over the gravel. Alliance has install videos at alliancegator.com.
Can any stone be used in a water feature?
No. Some stone does not hold up to pool chemicals or constant water. Tell us the use and we will guide you. See choosing stone for water features.
Visiting and delivery
What are your hours?
Monday to Friday 7:00 am to 4:00 pm, Saturday 7:30 am to 3:00 pm, closed Sunday. Please arrive at least 45 minutes before closing.
What should I bring to the yard?
Measurements of each area, your landscape plan if you have one, and a photo of your house.
Do you deliver?
Yes, Monday through Saturday. Palletized stone goes on a flatbed truck with a forklift, not a dump truck. Call for a quote.
Where are the best deals in the yard?
The clearance area, with heavily discounted stone we are not restocking.
Where can I get bulk gravel, bark or soil?
Roundtree Rock & Gardening, our sister company in the same yard, sells bulk gravel, river rock, decomposed granite, bark, soil, sand and compost.
