"Jon came out for the annual maintenance on my water softener and R/O system. He quickly tested my water to make sure both systems were working correctly and replaced the filters on my R/O system. Everything went smoothly."

"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.

"Carter installed a water softener at our old house about four years ago. The softener has worked great and has been trouble-free - just throw a couple of bags of salt in the tank every month. We recently moved and called Carter to move the softener to our new house. Jeff is punctual, courteous, prepared, and professional. High quality unit and installation at a reasonable price. Great company."

"I have needed to have these guys help me with my plumbing needs since I bought my home in 2005. None of the big name companies I've hired for help with my bathtub faucet drip did what Ricco did. Persevere, determined, to figure out if he could fix my cold water drip, ultimately, succeeding!! I don't want to tell his company how much he saved me...($400) by doing a fix instead of replacing entire pipe. Thank you, thank you, thank you! And, if I could post a picture here, I'd post the one with Ricco digging in to the repair inside my tub, while the apprentice supervisor over saw his work, my pug, Lucy sat quietly under his legs, and enjoyed getting petted. Thanks gentlemen!"

"Well, the first time the replacement was ordered it was the wrong one, which of course, delayed the installation a week. When it was finally installed I had to pay an additional $850 for code upgrades. This I was not informed of by Home Shield. Then we noticed that there was water on the garage floor and found that the pipe coming in from the wall was leaking at the wall so had to call the plumbing company back out to fix it. They first tried to say it was not their fault but since there wasn't a leak before they installed they did fix it. I have used Home Shield a few times before and never had a problem. Some of the companies they use are not the best so you have to research them before you commit. I have found HS service to be good if you do your homework. At the end of the day I was without hot water for almost 3 weeks but it was do to the plumbing company they sent out."
