"I’m a 70 year old Senior. I had sagging at the end of my hall, in my 3-BR ranch home. I got five other quotes, none of which suggests a problem with my foyer or kitchen. They sent out some 20 something young man -that clearly did not know what he was doing to complete my main beam replacement project. I mentioned to David (the 20 something) and his assistant IMMEDIATELY, that my kitchen cabinets had pulled away from the wall and the foyer was tilting. Several times. He assured me that he would run the beam right up under the kitchen between the kitchen and the foyer, to the garage door —to correct it! I had an intense disagreement with him when he tried to leave and did not make any attempt to correct the damage. The damage they had caused. I used my burial money to correct this sagging in the hall-and they left me with a huge problem with my foyer and kitchen that WASN’T THERE BEFORE, that they caused, & knew they caused. Indiana foundation, now Groundworks, sent Blake to my house under the guise of completing my first adjustment to the main beam, and as I had instructed them, to formulate their repair project based on a certified Home Inspection Specialist that I had hired to let me know what, specifically, Ind Found. should do to correct the serious problem they created. They promised to schedule the repair work at that time, but have ghosted to me ever since coming to see the damage they caused and formulate the repair. I have not been able to get in contact with them since; I’ve left numerous v-mails and texts. They have no integrity towards my project and nor will they have ANY integrity towards yours."

We are a family owned and operated company that takes great pride in a job well done. We have been fixing foundations for three generations.
"This company repaired all wall cracks in my basement and installed a drain system on all walls of my basement. This company showed up when they were suppose to and completed the work on my basement in a timely matter. I had to contact this company to come back out after the work was done but come to find out, the problem we experienced was not due to any of the work this company had previously done however they still repaired the problem without charging us anymore money. Would definitely recommend this company to others."

"In drilling holes in our laundry room floor they drilled two holes in a hot water pipe. The repair work and expense related to this was greater than the cost of their work. No verbal or written mention was ever made about identifying the location of water pipes. I assumed (mistakenly) that they were professional enough to either ask me to have this done or be able to do it themselves. Their response to my complaint was to send me a copy of my contract reminding me that they are not responsible for "cosmetic" damage and that complaints must be settled through arbitration. "

"I am very disappointed with The Foundation Specialist. Their price quote was more than double that of a competitor, which raised concerns from the start. I canceled the contract within the 72-hour period as allowed under the Federal cooling-off rule, yet more than 10 days later they have failed to refund my $5,500 deposit. I have called multiple times and was repeatedly told that the sales manager would contact me, but no one has followed up. This lack of professionalism and failure to honor a lawful cancellation is unacceptable. Based on my experience, I cannot recommend this company to anyone."
