Who will I be talking to?
Greater Milwaukee Waterproofing is a referral service. We connect you with an independent local basement waterproofing contractor who serves your area. We don't do the work ourselves.
Does it cost anything to request an estimate?
No. Requesting an estimate is free. Inspections, quotes and prices come from the contractor; get a written estimate before work starts.
Is there water in my basement right now? What should I do?
If water is near outlets, appliances or the electrical panel, stay out and don't touch anything electrical; contact your electric utility or an electrician. Otherwise, check that the sump pump is running and its discharge isn't blocked, then request a call back and mention that water is coming in now.
How do I check a contractor?
Ask for proof of insurance, a written scope and warranty terms in writing, and look up reviews yourself. Compare more than one quote for big jobs.
Does MMSD help pay for a sump pump?
It can. MMSD's Pipe Check program pays incentives for one- and two-family homes in its service area when an MMSD Approved Contractor does the work. The table (updated January 1, 2026) lists $3,800 for a foundation drain disconnection with a new sump pump and $300 to reroute a sump off the sanitary sewer. The incentive is taxable.
Do I have to disconnect my downspouts in Milwaukee?
In the combined-sewer area of older Milwaukee and Shorewood, MMSD rules require it at homes of four units or less where city code allows. MMSD says to check with your city or village first, so the water doesn't flood a neighbor or ice a sidewalk.
