"It's always difficult to get someone who is willing to come by to fix those little annoying problems you have, but not Tom. I had 1 leaky faucet and 1 frozen faucet(due to hard water). Tom came explained what needed to be done and I hired him to fix it. Very pleasant to work with. Also cleaned up after all the work was done. I have his card now and will not have to stress when I need a good plumber in the future. No job is too small for Tom!! He will be back in New Year to install a tankless water heater."

"Wilfredo did an excellent job! Not only did he replace a leaking outdoor water faucet, he discovered that our water pressure regulator (PRV) was defective, which was causing numerous pressure problems with all our appliances, toilets and hot water heater. Fantastic diagnostics! Really impressed and likely saved us many future problems. Very pleased with service!"

"This was probably my best experience on Angie's List. I woke up and noticed there was no hot water in the house. Went to the basement and noticed the hot water heater was leaking. I called up Advanced Professional Plumbing, told them what was going on and gave them the specs of the hot water heater. 20 minutes later a technician showed up (a very nice guy named Joey). He inspected everything and showed us the cause of the issue. He gave us a few options on what to do and we decided to replace the 75 gallon hot water heater. Within an hour, Joey came back with Sam and they replaced the old water heater with a new one. They were both professional and got the old hot water heater without making a mess and replaced with a new one. After the job was done, Joey tested all the bathrooms out to make sure the pressure was good and we paid and they were on their way. They were fast, efficient, explained everything and it was a great price. You really can't beat that. Your hot water heater breaks down on a Saturday you are not expecting hot water for the rest of the weekend but Advanced Professional Plumbing delivered. I appreciated the office following with me to make sure everything went. Just an overall class business."

"Service Tech Ed DeMore, who had originally installed our tankless water heater, responded and realised the unit had to be reset and recalibrated after an error message caused the unit to stop and not restart during the snowstorm of last Monday. He had us up and running in just a short amount of time. Eddie is an excellent and knowledgable employee with a great attitude. He is very pleasant and we hope A. J. Perry realises what a great asset they have in Ed."

"I called All Weather to give me a quote for replacing my gas boiler. They set up a time for their salesperson to come over and give me a quote. The appointment was only a few days later and a man named Joe showed up on time. He spent some time with me, I told him I was looking for a new boiler and a new hot water heater, but I wanted to see what options I have (since I was debating going to a tankless water heater). He told me going indirect hot water tank is the best option and they always use this brand that's the "best one out there". Even though he may have been right, he didn't tend to my questions or concerns very well. I felt like he was getting annoyed that I had questions and eventually I just let him run the show just to get him out of my house faster. Especially when he gave me a quote of $8600, it was much higher than I was anticipating. One thing I really didn't like was when he said I'd have to get a permit since I live in an incorporated village, which would be an extra $500, meanwhile I already had another plumber tell me a permits only $200. So I went with another company. So even though I can't rate All Weather on their work quality, I didn't get a good feeling from their salesperson."
