Leo G Sirois Plumbing & Heating is a plumbing business whose Connecticut plumber license, number PLM.0204015-P1, is active on the state registry, with LEO G SIROIS as the holder of record. The Better Business Bureau gives it an A+ grade. A 2023 customer said another contractor wanted to dig up the yard and replace all the pipes when only one pipe needed replacing. That 2023 customer said Leo did the entire job and also placed a vent under the sink in 4 hours, and called the price very reasonable. In a 2023 review, a customer called Leo prompt and fair. A 2026 customer said they were charged much more than they expected for 2 hours of work replacing a kitchen faucet. That 2026 customer said the pipe underneath started leaking when it had not leaked before, and that they would have to fix it themselves.
Charged much more than I expected, for 2 hours work. He replaced a kitchen faucet, the pipe underneath started leaking, which didn’t leak before. Will have to fix ourselves, don’t want to have to pay for another visit.
Leo is amazing! He is very prompt and fair!
Thank you Leo! A contractor wanted to dig up my yard and replace all pipes when I only needed one pipe replaced. Leo came out and saved me! He did the entire job and also placed a vent under sink all in 4 hrs. Very reasonable on price. Will use him again.
