"I called at 8:00pm on a Tuesday night. The plumber came before 10:00pm as promised. He replaced a leaking shut-off valve and associated pipe within an hour. Cost was as quoted for one hour labor plus parts which were less expensive than expected. No extra costs for travel time or anything else. We will definitely use again."

"Markool was super professional, kind, and skillful. A few things really stood out. 1) He did a furnace flue piper install that he could have charged us much more for if he had wanted to take advantage of us - but he was honest and we paid less than we feared. He also went the extra mile helping my wife and I through a warranty claim with the furnace company so that we did not have to pay extra part costs. It was an unexpected need, but he was prepared with the part and worked with the manufacturer to get us covered. He was even able to better a previous repair. 2) On a home humidifier install, he made himself available on short notice, took time to answer our questions, and then showed us how to maintain the equipment ourselves so we wouldn't need to shelve out more for additional contracting work - even from him. Grateful!"

"This was a low complexity modification to a existing gas line connecting to a gas range. It took approximately an hour with two staff. One thing I was concerned about was the usage of a lighter to check for gas leaks. Typically this type of checking is done using soapy water as using fire to check for gas leaks can be hazardous."

"Extremely professional, courteous and respectful of my property. Explained the reason for upgrade and answered all questions. When necessary to hire someone to repair drywall after replacement of ceiling fans, they provided a contractor who did exceptional work."

"Darren, the Salesman, was extremely knowledgeable and helpful. Very low pressure sale tactics, but laid out all of the options for you. The crew came and finished installing a new heat pump and heat exchanger in a half day and then another individual returned the next day to install a new water heater. Great communication and attention to detail every step of the way! Would highly recommend!"

"Our plumbing system was 33 years old. Arts Plumbing completely replaced the entire water system, plumbing, water heater, water tank, some bathroom fixtures, and installed a water filtration system. We had outside hose lines installed. The crew was experienced, professional, efficient and friendly. Everything was organized, labeled well and they went over the system with us. They offered a few suggestions that really helped the efficiency of the system. It was a pleasure having them do the work, great people! We were pleased with the price and we will continue to use them for all our plumbing needs."
