Iowa Waterproofing Company


Iowa Waterproofing Company is a family owned business.  In 1890, Great Grandpa Seimsen started his business in foundation construction, we are no longer in foundation construction, but we are now one of Eastern Iowa's finest and oldest basement waterproofing and foundation repair companies.

Our family business value is to do the job right the first time at a fair price, rather than cut corners and make excuses for poor craftsmanship later.

We provide services in full basement waterproofing, power brace systems to hold and straighten bowed foundation walls, sump pump installations, emergency back-up sump pump installations and foundation crack repairs.
