“Jamison did foundation repair for me, and it was excellent. I liked the follow-up. The guys are pretty thorough, and they were very neat and tidy. It was great—they get an A+.”

“They were good. They were easy to communicate with, and they did a good job and followed up. Jamison did foundation repair for me—A.”

“They were quick; they were courteous and efficient and the job looks fine. So, it worked out really well. I had a crack in the sidewall of the house from the foundation, so they patched that up, cleaned it out, patched it up, and things have been fine. I would grade the overall experience with an A.”

“I liked that they were very nice, very clear, very professional, and attentive. They reinforced the foundation of my chimney from the outside and a piece of sidewalk that's attached to it. And from the inside, they put in studs in my drywall. I would grade the overall experience with an A. No complaints.”

“They provided both waterproofing work and foundation repair work for me. I would grade the overall experience with an A.”

“They fixed a foundation crack and a leak in our window well. They were professional, they gave us a good description of the work, and they were on time. They earned an A+.”

“We had a hairline crack in a cinderblock foundation. It was a finished basement that wound up having a decent amount of water and black mold, so we had a company come in and do the mold remediation. Jamison took care of the French drain, and they kind of sealed everything with a vapor barrier and did some waterproofing. These guys were fantastic. They're an A+ for sure. They were unbelievable, these guys.”

“It was foundation repair and waterproofing. I'm getting ready to sign another contract with them over the next week or so. I have no reason to not give them an A+ on the first job. I don't have any complaints. I'm going to sign another contract with them, so that says a lot. I keep putting it off. I was supposed to sign last week, but then that got put off, and I just got done texting the guy saying let's wait until after the holidays.”
