Dependable Construction Supply has been in business since 1989.  We have grown from a small two-man operation in Lake City to our current location on Highway 99 in North Seattle with over 30,000 square feet of inventory. 

Over the years we have responded to the requests of our customers, taking a long-term view of the market and have positioned ourselves to be the premier distributor of waterproofing and coating products in the Pacific Northwest.

We have established a rapport with our customers and understand the relationship between supplier and customer is something that should be mutually beneficial and profitable to both parties.  We take our responsibility very seriously and do our utmost to deliver our best each and every time.
