"recently had our water heater replaced and had a great experience from start to finish. The team was professional, knowledgeable, and completed the installation quickly and efficiently. They explained everything clearly, cleaned up after the job, and made the whole process stress-free. The new water heater works perfectly, and we couldn’t be happier with the service. I would definitely recommend them to anyone needing water heater replacement or plumbing work!"

"Angie sent me a contact for the water heater install on Thursday 7/14, with a tentative install of 7/16. That was changed to 7/17, and the plumber let me know that he wouldn't actually be available until 7/18. I had not had any hot water for 3 days, so when Mike from All Trades contacted me on Thursday and said that they could install a water heater on Friday 7/15, I was very happy. They took out a dead 30 gallon Sears electric hot water heater and were able to replace it with a 40 gallon AO Smith electric hot water heater on Friday 7/15, so I not only got a new top rated hot water heater, I got a 40 gallon replacement for the old 30 gallon heater. All Trades did a very professional job, and completed it within a time frame that allowed me to make a 1 pm Dr's appointment with time to spare."

"Mike McGovern and his son Brian installed a Navian NPE-240S2 tankless water heater and removed the old 50 gallon tank. The installation required new vent piping. Mike considered several options for routing the pipes and made an extraordinary effort to implement the venting with a maximum of six elbows as specified by the manufacturer to assure adequate venting, away from windows, while still providing protection against rain. It has now been seven weeks and the new installation has performed flawlessly. I could not be more pleased with the work."

"They offer service scale clean out of the thankless water heater. I may contact them at a later time for this service."

"Excellent work,made sure everything was working fine before leaving.I had diverters with springs in the back of them for a long time.I did not like them as they would break all the time.Cheap plastic.Brass valves and full turn knobs were put in.I love the new set.It is sturdy and will last a long time.Also a tub water stopper and a new over flow was put in along with new plastic pipe under the stopper.The stopper is great.All you have to do is step on it for water to go down or stay up.Very professional attitude.On time to do the work.Cleaned up after the job was done.Will hire for other work in the future."
