Recommended Customer Reviews

Mike is knowledgeable and upbeat. He takes pride in doing the highest quality work and remediating problems elegantly. His truck and equipment are state of the art, clean and well maintained. I highly recommend Dejusto Plumbing.

Mike installed a tankless water heater for me over the summer. It works perfectly, and the job was completed with care and quality. Mike has excellent attention to detail, is quick to respond, and he is great about explaining what he's doing and why. He is thoughtful and thorough with his work, and the space was immaculate when he finished the job. He is a STAR and always who we call when we need plumbing work done. And to top it all off, he's a wonderful neighbor! Thank you, Mike!

Mike DeJusto has expert-level plumbing skills to diagnose the situation properly along with the patience to make sure the job is done right. As a bonus, his competitive prices and ability to explain the best solution are significant benefits. If you hire Mike you will see that he knows exactly what he's doing and does it well.

Outstanding! Had a water pressure error on a tankless boiler in a very complicated setup. Mike spent the time to really understand the system and discovered flaws in how the system was installed causing a lot of the issues. Others told me (bigger company operations) to rip out the system and start over (1.5 year old system), but Mike figured it all out. Exceptional work & craft, proud of his work, and fair on his pricing.

Mike continues to provide five-star service with a cheerful attitude. He helped us out with a water leak emergency on a Sunday. He's very conscientious about cleaning up. He works very efficiently, which was much appreciated when paying weekend rates. He loves our pet tortoise and always has a kind word for her. We are very grateful to have found such a skilled plumber with his own business.

Extremely competent and responsive. We had an outside water leak and Mike responded with total professionalism and diagnosed the leak. We saved thousands using Mike. He also explained everything and was honest, friendly and upfront .

Mike is a God among plumbers!Our toilet cracked at the base and with two small kids, being down one toilet was a crisis. Mike made time in his busy schedule to come out to install a new toilet. In classic fashion, the new toilet we purchased from a big box store before hand had a cracked base in the box as well, so Mike went with the flow and rescheduled mid job while I got another toilet. Mike was punctual, kind, knowledgeable, and worked hard to get our toilet back up quickly. Highly recommended!

Mike is super knowledgeable. He took the time to research and crawl under the house to do a true inspection. I would recommend him to anyone.

HANDS DOWN BEST PLUMBER! Mike came out about a year ago to fix issues a different plumber made in our kitchen. He moved a gas line and changed out all piping under our kitchen sink. Fast forward to today on a Saturday I called Mike at 9:30am because we smelt gas. Mike was in his Pj's but didn't think twice about getting up getting dressed and coming to fix the problem. ON TOP OF ALL OF THAT HE DIDN'T EVEN CHARGE US! Best plumber in the business! Give him a call!

We had Mike come out to re-route a leaky gas pipe that went to the dryer. He jumped under the house, did his thing and hours later we had our dryer working again. He knows his stuff and he's now our guy for any plumbing needs. You don't need to look anywhere else. Thanks for the help Mike!
