"I used Plumb Tite to install a tankless water heater. The pricing was straight forward and fair. The service technician was professional and courteous. He showed up on time and cleaned up the workspace afterwards. I would definitely recommend Plumb Tite."

"Fast, professional and reliable team that made sure my family was taken care of when our water heater decided to quit in the middle of the winter. The team memeber that did the install was highly knowledgeable and gave us several options and didn't feel like he was just trying to take advantage of us. Will definitely be recommending maximum plumbing to my friends and family for their plumbing needs in the future"

"We needed to check our water heater for leaks prior to closing the sale of our house.Joe Lay were out installing a new water heater and expansion tank the next day. The technician explained how all the components were supposed to work before checking everything so we both knew we needed a new tank as well. Outstanding, professional company. Billy was very respectful, knowledgeable and professional the entire time in our home. We would highly recommend Joe Lay and Sons for any plumbing needs."

"Their services straightened up my drain and completely fixed my problem without having to dig up my floor. He used a jet wash high pressure water spray wash that cleaned out the interior drain.  He also sent a camera down the sewer line to check and see the rest of the drain. In addition, he gave me the advice on what to do with the sewer line and I thought that was nice of him to do that."

"Zak showed up on time, looked at my to be fixed list and went right to work. He was able to loosen the shut-off valves in both bathroom sinks, so we we didn't have to replace those. (I'm 70 and arthritic, no strength in my hands and wrists.) If the shower regulator goes wonky again, I should be able to fix it myself as Zac showed me how. No charge for that fix. The toilet needed a new flapper-apparently the el crappo one I had used was no good-it was worth the $15 charge to finally not have to turn the water on/off to use the toilet! The cost of the project includes the new faucet which I guess to be $80-100 retail range (a nice Delta basic with sprayer). It was not a simple replumb; there were some challenges getting the old faucet out as parts were rusted and fused. Zac explained everything along the way, took care not to make a big mess and cleaned up after he was done. Took about 3 hours start to finish, including the time Zac took to go purchase the faucet and get the special tools needed to cut apart the old rusted parts. They will be coming back to install some shower rails for us after they get the parts. I will be calling these folks for any more plumbing repairs I need. I was so nice to call and actually talk to a live person and not play phone tag. I called them on a Thursday afternoon and they were here the next Monday morning as promised. This was a non-emergency call. BTW-they do charge $85 for a service call. This was work Plumb Tech originally did in December 2017. I had washed dishes in a dishpan and when I dumped the dishpan, water gushed all over the floor. I called they sent a tech over immediately-here in about 20 minutes. Turns out my old house and somewhat wobbley sink cabinet contribute to loosening the joints. The tech re-attached everything and tightened all the joints as much as possible. Everything is now working fine again. Done at no additional charge to me. I really need to have new cabinets installed so the sink will not move even a little, but the house is not worth that expense at this point. (We will be investigating some way of stabilizing things.) I really appreciate the fast response and not being charged."
