Bonn was one of three contractors on Angie's List that I solicited for bids. I selected Bonn because of their responsive to providing an estimate and Rudolf's, the owner's, nice demeanor. In the beginning, Rudolf was on site every day with the crew, which was reassuring. I provided the crew with bottle waters, sodas, and snacks nearly everyday due to the hot temperatures. Bonn did a good job with installing the privacy fence. My only criticism with the fence is that I had to give too much direction on how to install the fence gate and I had to request a gate handle. And, the deck staining was good. However, I failed to select a good color so I will have to hire another contractor to restain the deck. The problem is with the quality of the concrete work. In the course of replacing the front porch steps, one of the crew left his hand print in the concrete, which was visible as the concrete dried. Also, after completing the work, I noticed that water puddles were forming in the area between the steps and walkway, which never occured before this job. I contacted Rudolf about these deficiencies. He listend to me but didnt seem to believe me, although I was visually pointing out the problems. Initially, I said that I would get a 3rd party inspector to review the work and convince Rudolf that there were problems. But, we decided not to occur an additional $400 for an inspection. Instead, I took pictures documenting the deficiencies. When I shared the pictures, Rudolf sent his crew to repair the steps and the walkway. But in the course of repairing the walkway, the Do Not Cross tape fell into the concrete and left an imprint. My concrete walkway NOW has the imprint from the tape. During the final inspection, I pointed this out to Rudolf but the conversation quickly went downhill. Rather than push for him to fix the imprint, I opted to just pay the balance to end this business relationship and my stress. Rudolf accused me of being demanding. I will be glad to share my pictures showing the basis for my demands. My only reponse to the accusation is that when a customer pays over $8000+ for a job, he/she has a right to demand the high quality work.
