"Let me start by saying Marco is an amazing plumber. We needed our main line replaced because it was getting backed up and out of all the plumbers that came to give us an estimate he seemed the most honest. He was very attentive and communicative. When I had questions he was always very informative. He was very reliable and clean. Will definitely be hiring him if we ever need to again."

"Wow! Gerrod at Valiant Plumbing would get 6 stars if I could give them. He was professional and did a fantastic job on updating two sinks and bringing everything up to code. He paid a lot of attention to detail, including cleaning old mineral deposits. He even saved the day when a refrigerator delivery crew needed a water line disconnected but wouldn't do it themselves, Whew! Pricing and schedule availability were very reasonable and he did not try to upsale anything. Also, just a nice, decent guy. I felt comfortable having him in the house. I'd hire him again in a heartbeat and would recommend him highly. First picture is before of kitchen faucet, rest are after pictures."
