Providing expert basement waterproofing & crawl space repair for a healthier home!

Did you know Jamison Basement Waterproofing is one of the safest companies on the East Coast...

Since 1989, Jamison Basement Waterproofing (knock on wood) hasn't had one insurance claim for a work place injury. That's over 25 years of safety excellence. If you ask most of the employees at Jamison Basement Waterproofing they would say it's just part of the daily habits instilled in them from the mangers down to the guy that sweeps the shop. We do have to give some of the credit to Ken McKnight, a Jamison Home Services Safety committee member who holds monthly safety meetings. Additionally, employees receive safety tips weekly from management. It is no surprise that Basement Waterproofing can be very dangerous work and Jamison doesn't take that lightly. If choosing a safe company is a the top of your priority list, then Jamison Basement Waterproofing is the company for you
