"Every single item that he has done at my house has been beyond excellent. Always professional in his work and timely. I have not had any issues with any work he has done and will continue to use his services. He installed a sump pump after the sump pit filled up and my basement got water. He cleaned the excess water, left a fan to air dry the basement, installed a sump pump with drainage to outside the house perfectly.
I needed my driveway power washed and entrance, he did it in a timely manner and it looked amazing.
The overall process with the company was beyond excellent.

"We bought a house recently. The inspection report called for installation of an expansion tank and lengthened drip leg on the HW heater. Jamison Plumbing had installed the new HW tank several months before for the original home owner. Jason called the City of Liberty to determine the exact code requirements. He called back and agreed to the additional work at no charge. He was able to make the changes in a timely manner. His crew called to say they would be later than planned because of an unexpected delay at the preceding job site. We appreciated his willingness to finish the installation according to code and to cover the additional materials and time. It was a great way to be welcomed into a new community.

"Initially, it went well. But I didn’t know what I didn’t know. The diagnosis of the problem was incomplete. Two large basement wall cracks (clearly visible at the time because wet dry wall had been removed) also contributed to the water issues and they were never discussed. In the fall of 2017, I came home from an overseas trip to find 2 inches of mud in my basement which had poured in over the drain tile installed by PermaJack. I reached out to the company a couple of times and was told I would be contacted the next week for an inspection. But this never happened. On the advice of my real estate agent, I turned to a different company for an inspection. The cracks were clearly diagnosed as a major issue. And when the drain tile/sump pump system installed by PermaJack was inspected, it was found that the drain tile was improperly installed. The pipe laying in the drain tile reservoir was twisted so that only a third of the holes in the pipe would even come into contact with water at any one time. In other words the system was easily overwhelmed and shouldn’t have been. In addition, the system should have been installed under the sill, the wooden board I left in place after ripping out the dry wall. Because it was installed in front of the sill, it never came into contact with the corner of the foundation and water could easily come into the basement over the drain tile. I realize at the time of the installation there was lots of water damage throughout St. Louis from the massive spring storm. But in retrospect, it seems like the job was rushed and for that reason it was not done properly. Also, when I reached out to the company to inspect their work, they were fairly unresponsive. They did say they would call me, but they never did."
