"Junior, owner of the company, came out to give me a quote on moving a gas line in my kitchen. Very personable and very knowledgeable. He listened to what I wanted, we agreed on a price, and he started the work right then. By early evening, him and his crew had jack hammered the kitchen floor, trenched from an island to the wall, installed/extended new gas line to the proper depth, backfilled everything and completed the project with concrete and a connection concealed in the wall cavity as requested. Excellent work, excellent customer service and clean up! They even moved my stove into place and connected it before leaving. Definitely not a 'one and done' company. I would recommend this company to my friends for any plumbing need!"

"Andrew was our plumber and also the owner of Service Flow Plumbing. He is everything you want in a professional tradesmen. He was polite, prompt, respectful of my home, thorough, very efficient, and was very generous with his time answering all my questions and showing me how to fix my next faucet handle. His rates are reasonable especially when you consider the level of attention he gives to your problem. I'm telling my family and friends about him & his company because service like his is unfortunately too rare."
