Dannegger Brothers Contracting

Richard came out to my house in St Charles, MO and took at a look at my sinking sunroom. He gave me a quote and did the work at exactly the quoted price. They were efficient, professional, and extremely friendly. They also listened to and answered all of my concerns and questions. Thank you Richard and crew for doing an absolutely fantastic job. Keep up the great work. I highly recommend these guys to anyone needing foundation repair.

Dannegger Brothers Waterproofing installed a waterproofing system in my basement and it did not work. They installed perforated corrugated flexible plastic pipe under my basement floor to correct water leakage between the floor and the wall. They wrapped the pipe with filter cloth to keep out stones and sand. Within three years the filter cloth plugged with mud and my basement began to leak again. When I complained, they offered to fix it by tearing up my finished basement again. I was not about to go through that disruption and have yet another ineffective installation. After spending thousands of dollars on waterproofing, I later discovered that by making simple changes to my patio and downspout drainage and keeping my gutters clean, I could totally prevent the leakage in my basement. Now my basement is dry and the sump pump that Dennegger Brothers installed never needs to run.
They also mud jacked my sinking front porch and installed a low-​tech concrete pier under the porch retaining wall. They used stone-​age equipment and the jackhammer operator didn’t wear eye protection. The porch repair was effective but they left the plywood concrete forms under ground, buried along side the pier. Now I have buried wood next to my foundation to permanently attract termites to my home.
I do not recommend Dannegger Bros.
