I had been doing a DIY plumbing job for a full gut job renovation of my house. The inspector informed me that since I had done some modifications to my basement plumbing I would now need to install a backwater valve (per the city bylaw). I also had a basement apartment which would require separate lines for the basement and upstairs systems. On my way to the house the next day I saw a Master Drain truck on my street and flagged them down. The foreman came over right away and had a look, then Vitaliy showed up a few hours later. He quoted the job on the spot, explained exactly how he would do the job and gave me a price. I got two other quotes, one much higher and one fairly similar but giving me less confidence. Vitaliy was extremely responsive, followed through on literally everything he said he would do and more, and the job was finished exceeding my expectations for time and quality. I also asked him to replace my main water line with 3/4" copper and they did it in a day, even managed to save my wife's boxwood plant that was in the path of destruction and returned the site to its original condition. These guys are good at what they do, take pride in their work, and I recommend them without hesitation.
