"After living in our home for over 20 years heavy rain coming off the roof had caused the terraced landscaping in front of the house to sink about a foot and the concrete terrace blocks were nowhere close to level. We had a landscape engineer look at it and he never got back to us. We had a concrete guy look at it and he never got back to us. Then we had Chris with Professional Contracting look at it. He said he believed he knew what to do, which was to build two parallel retaining walls. In addition the steps to our house had also sunk down nearly six inches. Chris proposed building new steps and a new sidewalk, as well as a front patio (where the bulk of the water was channeling off the roof) to direct the water away. He seemed confident and we felt like he knew what he was doing, so we hired him. He and his crew arrived when promised. Chris works very hard and implores his crew to do the same. As they were working we decided to add another small front patio and a large back patio and Chris and his crew adapted to this change without complaint or delay. If anything, the two retaining walls were overbuilt. When they were done Chris made sure the ground around the concrete work was properly sloped and they cleaned everything up. About five months later I noticed that the one retaining wall was moving, being pushed by the dirt it was supposed to be holding back. Chris came to look at it. Given that it was overbuilt, we were both very surprised that it would start to move. Chris took full responsibility. He and his crew came back and excavated the dirt from between the two walls and installed very heavy chains from the top of the one that was moving to the base of the other one, to prevent any more movement. Then they filled the dirt back in so that you could not tell they had been there again. Given our confidence in Chris at that point, while they were doing this repair we had them install another sidewalk. Chris did the repair work without any charge. Chris will tell you that he is not the cheapest, but that he will do the job right. We firmly believe that to be the case. The fact that he came and fixed the movement of the one retaining wall promptly, and at a significant investment of time by his crew, with NO charge to us, proves that he will do things right or he will fix it. It has now been two years since this work was done and everything is looking good. You can probably find someone to do concrete work for less but you will not find someone to do better quality concrete work and to guarantee the results."

"They do excellent work. Very particular."

"Aaron was timely in response and was quick to schedule an inspection. Willing to travel and very reasonable in price even with the travel expense added in. I would recommend Aaron for verifying the structural soundness of a foundation and will definitely keep his name in my list of preferred business professionals to work with."

"My husband and I had spent 13 years remodeling our 1873 house by ourselves. When it came time to do our dream project of adding a sunroom, finding a contractor to do the work instead of doing it ourselves was a very important decision to us. We met with several contractors and knew instantly that John and his son Nate at Addition Doctors were the people we wanted taking on this project. John and Nate were so great to work with. They were the only company we met with who gave us a computer generated model of what the project would look like so we had a very clear vision of the end product. They were the only company to quote us the project under the budget we told them we had to work with. They kept us up to date at every step of the project and there were never any surprises about cost or timing. They had great ideas for the project when we weren't exactly sure what should or could be done. We love our finished sunroom. The quality of work and service they gave was excellent. We would highly recommend Addition Doctors for anyone who is looking to have quality work done to their home."

"Our relationship with Tim was an exceptional one. We live in a house he designed, can not find any problems with it, he did a great job. The plans exceeded our expectations."
