"Mr. Hollister was great! I was really impressed with his promptness, quality of work and friendliness. The plumbing was the smoothest process for our 2nd floor addition project. Thank you Mr. Hollister for your great work, patience and flexibility! I would hire him again."

"Everyone I spoke to at Cotti-Johnson from the estimate through to installation of my generator were polite, professional and a pleasure to deal with. At the outset, the scope of the project and its cost was explained to me in simple and understandable language. The installation took place precisely on schedule and was completed within 3 hours. I received the necessary follow-up calls from the office to ensure the work was done to my satisfaction. I couldn't be happier with Cotti-Johnson."

"My grandson flushed his little yellow bus down the toilet Friday afternoon. I called several plumbers in the area. By late Saturday afternoon I had only 1 returned call saying they could come out Monday morning. A friend suggested I call Gentille Plumbing and Heating. I called them and they said they could come early Sunday morning. Ryan arrived promptly as promise and quickly determine how to approach the issue and retrieved the little yellow bus. Cleanup was quick and pricing fair. Ryan was professional , friendly and was on his way within 45 minutes of arrival. Thank You Gentille Plumbing and Heating"

"Showed up at promised time with all they needed to replace the water heater and completed the work in under an hour. Not my usual experience with plumbers. Price was the lowest of three I contacted."

"Excellent work! Beautiful job mounting the water heater and hooking up all the connections as well as installing a new electrical outlet. Bill came prior to the job in order to create exit piping due to our new siding job that was in process- much appreciated! He spent quite a bit of time explaining the systems we might choose and answering our questions. Very professional and a pleasure to work with. Everything was immaculate when he finished the job. Highly recommend!"

"I cannot recommend these guys enough! I am not a patient person, when it comes to work on my house. They EXCEEDED my expectations! Their install was professional, well communicated, clean and efficient. Work was done while my twin babies were home, and they were incredibly accommodating. Their service people have been quick to reply to every question I have had after install was completed. I, honestly, will never have to shop around again - Comfort Professor will be my first and only call."
