Welcome to Langley Hill
Langley Hill is a beautiful site atop the Santa Cruz Mountains, on California Highway 35 just south of Spring Ridge and Highway 84 at Skylonda.

Langley Hill Quarry offers convenient local rock and gravel supply, and some of the best septic system design and installation service on the Peninsula.

We are a local family-owned business, providing service here for many decades.

Take advantage of our special local expertise when it's time to improve your own home or business property. We look forward to working with people who are investing in our community.
