Premier Retailer of Landscaping Rock & Boulders in Seattle, Bellevue & Snohomish County

For over 60 years, Builders Sand and Gravel has been the premier retailer of landscaping rock.  We deliver landscaping rocks & boulders in Seattle, Everett, Bellevue & Snohomish County; We deliver anywhere in King and Snohomish Counties. As with all of our products, we serve residential and commercial customers. If you have a small job that requires just a few stones, or large jobs requiring several truckloads, Builders Sand & Gravel has you covered!

Rockery rock is the type of landscaping rock that we specialize in. It can be used for a rock wall or a decorative garden feature, and we sell many shapes, sizes, and colors. The primary type of rockery we sell is basalt rock from the Iron Mountain Quarry in Granite Falls. It is blue-gray color with varying white veins and sparkles. We feature this rock because it is native to the area and goes well with northwest landscaping. The quarry's close proximity to jobsites in Seattle, WA; Everett, WA; and Bellevue, WA allows us to sell this landscaping rock for a lower cost. This is a blasted/fractured rock, so it has flat sides and sharp corners. It works very well for stacking and building walls.


Blue-Gray Basalt Rock & Large Round Boulders (By Request Only)

In addition to the blue-gray basalt rock, we sell large round boulders by request only. We have cobble rock to make the look of a dried up river bed. Our trucks deliver the perfect landscaping rocks to line your flower beds & for rock gardens.  

Builders Sand and Gravel has a retail yard in South Snohomish near Woodinville, WA where you can see the rock before and even save money and haul it yourself. Remember, we always can deliver anywhere in King or Snohomish county, so if you live in or near Seattle, Bellevue, or Everett, WA please call Builders Sand & Gravel for your landscaping rock!


Cobble Rock

Cobbles or oversize are larger "river rock." They are used primarily for landscaping to create the look of a dried river bed or to border a flower bed or planting strip.
