Company Profile

Siper Quarry, LLC was formed in 2005 to provide Whatcom County contractors an additional source for rock products many miles closer to Bellingham, Everson, Ferndale, Lynden, and Sumas than other sources.

Our primary goal is to provide rock materials such as quarry spalls, crushed rock, armor rock, light and heavy loose rip rap, ballast, and landscape rock at or below market prices without sacrificing our first class operations. The pictures you see on this web site are a demonstration of our operations.
