Simple Tips to Protect Your Plumbing
We recommend a few simple habits to keep your system healthy, starting with regularly checking your water pressure. High pressure can strain your pipes and lead to "pinhole" leaks over time. Additionally, performing annual water heater flushes by draining a few gallons of water can prevent the mineral "crust" that often burns out heating elements in our region. Finally, it is vital to watch what goes down your drains; we strongly suggest avoiding harsh chemical "drain cleaners," which can eat away at the older pipes found in many Ontario homes. Instead, opting for professional hydro-jetting is a much safer way to clear grease and roots without compromising your plumbing's integrity.

“Glad I reached out to these guys when a family friend needed help with plumbing issues that had them shutting off their water and heating water just to shower. These guys were prompt and thorough, and about $1K cheaper than another local shop (not naming names, but shame on you, we thought you’d be better). Funny enough, this company is also family-owned, just more modernized and organized, which is a huge plus!”Monica G.

“Scott McLeod Plumbing showed up in my time of need and truly saved the day. They were helpful, reassuring, and professional during a very challenging situation. I had previously worked with another plumbing company that left me uncomfortable with some questionable accounting practices, but Scott McLeod Plumbing completely restored my faith in both honest and quality service. From start to finish, everyone who worked on our project—Teddy, Peter, and Michael—was pleasant, professional, and respectful of our home, including our landscaping.

“We had an issue with the plumbing in our master bathroom develop over the weekend. This had a sudden onset and very odd pattern. On Monday AM we called Scott McLeod Plumbing and to my surprise, they were able to send out a team a few hours later. Based on our description of what was happening, and his inspection of a few things, Teddy deduced immediately what the most likely problem was and explained to us the sequence of events that caused our problem. It was so logical and was communicated to us so clearly that we immediately felt complete trust in the solution he proposed. He was very obviously a complete expert. The cost proposal for all the work was very reasonable. He and his assistant spent the rest of the day solving our problems. It was such a pleasure having two such lovely people take care of our issues. I have used another top-rated local plumbing company in the past and although they did good work, I felt like their pricing was very high.”Happy Customer
