Mark Williams

Founder & Owner

Iowa's Top Basement Waterproofing Experts

Welcome to B.A.M! Basements and Masons — Central Iowa's premier basement repair and masonry company. BAM is a local business founded in 2012 by Mark Williams. After working several years with different basement repair companies, Mark saw a need for better value and customer service in the industry, so he decided to open his own business.

"Every consideration is given to total customer satisfaction with the highest quality workmanship" — the pillar of the B.A.M! name.

With over 100 years of combined experience in the stone, brick, and block masonry industry, BAM is number one in the Midwest for basement waterproofing and foundation repair. Mark strives to bring back old-fashioned integrity with a modern look — combining strong values with modern technology.

He says, "Too many companies let modern technology take over their values and customer service, and this makes them lose the WOW experience for their customers."
