My water line was old, lead and just 1/2” (very poor flow ) so I decided to replace it with cooper 3/4”, but I did not want to ruin my front lawn and also do not spend a fortune. After research I hired Water Guard, which met both criteria. They use trench less (Torpedo) method. For my satisfaction a very friendly and professional team showed up at agreed time and did the job fast, with precision , minimum disturbance. I warmly recommend for any plumbing services “ Water Guard (PV Drain Services Inc) in Toronto.A big thank you to Mike and the team at Water Guard  !

⭐️⭐️⭐️⭐️⭐️I had the pleasure of working with Water Guard Plumbing and I can honestly say the experience was outstanding. Mike and his team (Pavlo, Vova, Alex, and Andrew) were an absolute pleasure to work with.From start to finish, they were professional, detail oriented, and clearly very experienced at what they do. What stood out to me just as much as their skill was how friendly, approachable, and easy to work with the entire crew was. As a general contractor, I work with a lot of trades, and this team truly went above and beyond.I would recommend Mike and his crew to anyone who wants plumbing done right the first time. These guys really set the bar high!
