"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."

"Absolutely outstanding service! James from Essential Plumbing was professional, respectful, and transparent from start to finish. After being overcharged by a big box store contractor who left my pipes in a mess, James came in, assessed the issue, explained everything clearly, and fixed it perfectly — all for a fair price. He didn’t try to upsell me or scare me with fake repairs. Just honest, skilled work by someone who truly knows his craft. If you’re tired of being overcharged or talked down to by big companies, call James. Thank you, Essential Plumbing! You’ve earned a customer for life."

"Wesley was extremely responsive. He made all efforts allowing us to continue doing our business at home while he was assessing the problem, assembling his crews, and obtaining a City permit. We were well informed of the progress. His crew did an excellent and clean job, working long hours getting the job done. Including excavated to a depth of 10 feet, patched up our concrete driveway and patched up the AC roadway nicely. Wesley even found time to replace our kitchen faucet and under drain without extra charge. Don’t believe he would be the cheapest initial estimate you would get. We would definitely ask him for all future plumbing needs."
