"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."

"Great. Neil's crew did a fantastic job. They worked quickly and you could tell they were confident in their work. We had used DeWit Construction several years ago at another home (this was before the roofing section became it's own entity) to put on a new roof after damaged during high wind/hail storm and also to rebuild the underside of an upper deck which had not been correctly supported. We are already considering them for another project."

"Great ! Owner Tim came out and did an emergency tarp -- in the rain, as my BR ceiling was leaking. Jan ( office manager ) worked with my insurance until the bid & repairs were enough to give me a great outcome. Their repair guy was professional, friendly and did a good job. I would not hesitate to use them again & to recommend them !"

"Evolution design worked with me on designing and addition for a 100 and 5 year old house. We worked on the dimensions of the addition Plus the materials. Evolution understood the local zoning which was amazing that they knew that. We have not started construction. And evolution can help pull the permits and I'm considering them for that as well. All in all it was a long project but it was done efficiently, working with several of the staff an the departments."

"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."

"I was really under the gun due to a prior Architectural firm not performing their duties per building plan codes. Not only were the plans incomplete but the City Plan Reviewer states(The Worst plans he’s ever seen) they will not make adjustments unless there is an additional charge for Thousands. Evaluation’s saved my clients and drew our project per code, along with Engineering in less time then they quoted. I highly recommended them, Especially Kirsten. You went above and beyond trying to coordinate this project. The staff was very professional and I will use them on all my projects. Sincerely, Frank B BCM Builders"
