"Circumstances with my basement caused them to do a system that they hadn't done before. Had some leaks that caused some reworking."

"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."

"Anchored Walls made it easy to get the work completed. Estimate was done quickly and professionally. I spoke with 2 other companies who were impossible to chase down for estimates. Anchored Walls always answered their phones and made the entire process stress free. Would recommend and use again, need be.

"I am a very busy person, so I often get referrals from trusted people to save time. I personally know many happy customers who had work done by this company, so they were the only place I called when I needed my home's foundation repaired. I knew it was going to be a huge job. In Nov 2014 they came out to look at our failing foundation walls and give us a quote for the work. One wall had been replaced in the 1980's and was fine. The other 3 walls were clay brick. Two of the walls had huge cracks and were falling down. They needed complete replacement. The other wall wasn't cracked and looked ok to me. They said it did not need to be replaced, but that it did need to be braced. This was not presented as "option" so much as a necessity for the home to have a solid foundation. The original quote for 2 new walls and one braced wall was about $36,000. We approved the quote and scheduled the work for the earliest time which was in about 3 months. All along the sales guy and other staff members were very professional and friendly. To prepare, we had to move our air conditioner, some fencing and a few other things to allow access for the crew.The week before work was to start a guy (not the salesman) came out to do a final inspection and make sure those things had been done. Much to our surprise, he told us that they could not brace the wall as they had originally recommended. I was told that they don't brace clay brick walls because it is not effective and the only option is to rebuild the wall. I was then put back in contact with the salesman to discuss the issue. He said it would be an extra $15,000 to do the work. This was not good news. Then he told me that the wall didn't really need replaced and so they could just replace the other walls and do nothing to the 3rd. I was confused. Three months ago he told me that the wall needed braced . A couple days ago the inspection guy said it should be replaced. Now I am being told it's fine? His explanation was that the bracing option wasn't so much to fix the wall as it was to prevent a problem. I asked, why did the other guy say I need to replace the wall? His explanation was that clay brick is not the best foundation type and ideally should be replaced. However, the wall at this time is stable so I didn't need to replace it. Then I asked; why was I told to brace a clay brick wall 3 months ago if that doesn't even work? Basically, he said this was his mistake. He tried to make it right by getting the owner's involved and we had many discussions by phone. He made himself available at all times of day and was always professional and friendly. Unfortunately, I had lost my confidence in their recommendations. Did my wall need braced, replaced, or left alone? I ended up calling about 10 other basement companies to sort it out. All of the companies agreed that the walls would not be fixed by bracing them. They all agreed that the two cracked walls needed to be replaced. They all agreed that wall in question was currently stable and we could wait until it becomes a problem, but that it makes better sense to replace it now since we are already tearing out the other 2 walls. We agreed and went with another company who replaced all 3 walls for almost $19,000 less than the quote we got from Midwest. I don't think Midwest was out to get us or anything like that. I think there were some internal issues with communication that led to our problem. They were very professional and I think that if we had gone with them, the work would have been done right. Although my experience was initially very frustrating, it forced me to get more than one opinion which I should have done from the start. Ultimately their mistake led to me saving a ton of money and getting the sturdy, dry foundation that my home needed.
