"They are great to work with. Communication was superior. They stand by their work. A few years ago I had waterproofing done in my basement and this time they spray foamed the cavities of the basement too. Both times they did awesome work and cleaned up too! I highly recommend this company!"

"According to the website, the person we met with is a "Foundation Expert." Per his advice, we needed about $8000 in beams because the cement blocks showed bowing/cracking. This house is only 650 sq feet and built in the 1950s. He basically implied that the walls had extensive damage and the house would never sell unless we put beams up. He deemed the repairs done by a previous homeowner as very bad and said they needed to be fixed immediately. The waterproofing system was an additional $3500.
The whole thing seemed more like a sales pitch using the fear factor of a bad foundation. And, I was put off by the "buy now" price difference. They would give me a "realtor discount" if I agreed to do the work and pay the deposit right away. Like I'd ever spend $12K without getting other bids and researching the heck out of it.
We decided to hire a structural engineer that wasn't trying to sell us something to inspect the basement and foundation. Paying the engineer a couple hundred bucks was worth every penny. After a full inspection, his professional opinion was that there were no structural issues. The engineer report states that while the repairs made by the previous homeowner made were "unsightly" they are effective. Meaning - the method they used was ugly, but the support it provided was effective and adding additional beams was unnecessary.
I would highly, highly recommend getting a structural engineer before hiring any company to basement repairs. It saved us about $8000.

"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.

"They did many things besides what I'm able to list from leveling the ground and installing the drain system to pouring concrete throughout the whole basement, they also fixed the foundation where the walls were caving in and did an excellent job"

"I had multiple companies who come out and they were the one who had the best presentation. The price was very comparable and the work was great. They did a great job completing the work within the time frame and cleaning up."

"All phases of the job went well. The technician was courteous and respectful in every aspect, he even covered his shoes to prevent any potential transfer of debris or shoe markings to our hardwood floors. He did an initial assessment of the condition of the current pump and verified it's failure. He then presented us with several options for the replacement . The work was completed in a timely manner and the work area left in good order."
