"Please see the earlier review (3/12) for context. I wanted to take a moment to share my experience with Mt. Valley Foundation Services regarding our sump pump installation. Overall, the team did an excellent job with both the initial installation and the subsequent repair of the discharge lines, which had come apart over time. They were professional, transparent, and truly seemed to care about the project. The only challenge I encountered was not with Mt. Valley Foundation Services itself, but rather with its parent company, Ground Works. From my experience, Ground Works has acquired many smaller foundation companies across the U.S., and it seems they may be struggling with logistical coordination. The call center they use is not very user-friendly, and I experienced multiple miscommunications and scheduling errors. Unfortunately, this puts Mt. Valley Foundation Services at the mercy of Ground Works' logistical issues. That said, I highly recommend working with Mt. Valley Foundation Services. My advice is to obtain the names and direct contact information of the service team when booking—this makes future communication significantly easier. Once I was able to reach the team directly, they went above and beyond to accommodate my needs. Living in a flood-prone area, I feel confident that the sump pump project they completed will be a tremendous benefit to our home and property. A big thanks to Danny (the manager) and his team for their outstanding work!"

"I'm very dissatisfied with this company as a whole. After giving my deposit, I was told they would be to my home on a set date and time. They didn't show up on set date and didn't call or text as to why no one showed up. After calling several times, the next day someone calls apologizing profusely but gave no reason as to why the workers didn't show up. When you finally get them to come, they start the project and then the cat and mouse games begin! They'll call and say they have to finish another project and would be there a little later and then call back because that other project ran longer than expected. It's now 4 months into what I was told would be no more than a week! Calling the company itself about what's going on or complain is absolutely impossible, if someone does answer the phone, they give you the run around. Parts of my electrical was messed up by their worker, I was told that they would take care of it right away. Lies, lies and more lies with this company!"

"I complained twice and they had to come back out twice because they didn't apply the insulation as thick as I paid for. I assume because they were angry about coming back out they covered up two of my vents so I can't attach the pipes to them. I can't even find the ends. I will need to dig the expensive foam out to find them."
