De Keyser just put in a water lateral for us. Kurt, Bryce and the team were fantastic. I was surprised by the excellent clean up to restore the yard at job completion. At first I thought the pricing seemed to be a little high. When they showed up and I saw all the equipment it takes to do the job, I totally understood the price. Once the job was complete they said it went better than expected and had a reduction in price. They are so easy to business with. Exceptional company. Thanks Kurt.Posted on Google![]()

Had a water main break infront of my house late one night, De Keyser crew was out the next day and had it all fixed/ cleaned up/road hot patched, before I got home from work... My sump pump use to run pretty much steady for years....! Must of been a leak and the water followed my lateral to the house, no leaks any more. Thanks for the fix boys!Posted on Google![]()

Storm Sewer vs. Sanitary Sewer: Why the Distinction Matters
Storm sewers carry rainwater and snowmelt to local waterways, while sanitary sewers carry wastewater to the treatment plant — keeping these systems separate and functioning properly is a requirement of Green Bay’s municipal code. Cross-connections, cracked pipes, or aging infrastructure can allow stormwater into the sanitary system (or vice versa), leading to costly fines, backups, and environmental violations.
De Keyser Construction installs and repairs both storm and sanitary sewer lines to city-specific standards, helping developers, municipalities, and property owners avoid compliance issues before they start.
