No respect for the lake, wildlife, or people in general. Their equipment has been sitting on Green Lake, unmanned, with no permit for multiple summers. They have destroyed nests, parts of their barge have fallen in to the lake, the barge is completely unsafe, and its clear they don't care. Its ugly and a hazard to everyone nearby.

I had both rip rap a a permanent dock put in.
One of the biggest reasons I went with Radtke was their responsiveness and customer service. I was quoted by several other companies in the area and Radtke definitely came through. So pleased with their work!

Radtke destroyed the drainage in my yard due to their negligence. They refused to correct the damage they did. They are not a good company

They obviously don't follow the laws driving on the highway since they don't put the cover over their load on as they're driving on the highway. They better hope we have no cracks in our windshield or dents in our hood from the amount of rocks that flew off and hit our window and van! Common courtesy for the rest of us! Radtke, you don't own the road!

Extremely rude owner When I went to call the owner if he worked on the sea wall in Omro. before I could even explain what happened when I said I had a complaint he hung up on me. Then threaten a law suit due to poor rating, his workers were NOT the workers that tormented my grandchild it was the city worker. Regardless, before I could even state or ask the situation the owner slam the phone on me. I did call back and ask for somebody else but I was told he is the highest up he is the owner so it was verified by the person that answers the phone. So his workers are not the ones that approached my grandson but the owner is the rude man I spoke to on the phone that rather hang up then hear the full story.
