"CMK was very professional from start to finish. They showed up on time and very quickly repaired my burst pipe. I will definitely be using them again for any of my plumbing needs."

"Had a great experience (so far - we have a lot left to finish on our project) with Daniel from Cotti Johnson. They are clearly a well-established and highly professional company. He spent a lot of time going through our 110 year old home to check every outlet and inspect all current wiring for a planned electrical upgrade. He found some scary patch jobs that were quickly remedied and I liked that he presented the “good, better, best” options to us and we were able to land on things to do immediately to correct safety and code issues and plan for a return visit to handle the upgrades. Most impressed that they were reliable and actually showed up which has not been the case with many other Cape contractors/tradespeople we’ve tried to hire this summer. Top notch and would use them again."

"They came to my home showed me what needed to be done and they went and got the water heater. When they came back a short time later they had the tank and installed it in an hour with new pipes and a new shout off that I can do."

"Our experience with All Phases Mechanical has been excellent. On the first occasion we used APM, we lost heat during a cold snap in the middle of winter. We called in the morning and a technician arrived that afternoon and quickly determined that not only was our 20 year old furnace in need of expensive repairs (which a friend of ours in the construction industry validated), but continuing to run it would potentially result in a carbon monoxide hazard to my family. Carl gave us clear options and helped us understand benefits (rebates, no interest loans, etc.) that are available from the state to assist families in our predicament. We decided to move forward with a new furnace and Carl's team installed it the next day. On the second occasion, APM helped us our central air conditioning system. Again, Carl sent a technician who arrived promptly the same day, who determined that the air conditioning system was fine but it wasn't working properly due to faulty wiring. He quickly fixed it and was on his way - all at no charge. I can't say enough about All Phases Mechanical. If you're looking for a local company that cares about its customers (and understands that heating and cooking problems need to be addressed quickly), All Phase Mechanical is the company you should use."

"All three jobs went great. For the water heater replacement Lewis came to my house at a convenient time for me, removed the heater changed out the rotted pipes and installed a new one with warranty. The price was great too. This job was time sensitive and he made me a priority to get it done. For the bathroom tub drain unclog he was very professional and did a great job. My garbage disposal was leaking and I came home to a pool of water in my cabinet and on the floor. Lewis came out quickly to resolve the issue for me. He replaced everything under the sink and showed me what he was doing each step of the way. I think that he is a great plumber if you want to get quality work and learn about each job too."

"George called back right away and showed up the next morning. I had a few quick fixes and repairs (leaks, pipe + fixture replacement). He was very knowledgeable and qualified. Work was excellent. Price was high/premium but this was on a Sunday during a holiday weekend so I can't really complain. Great plumber is you have an emergency and care more about reliability and quality over savings."
