We are so impressed with Matt Mertz plumbing. We have rented our 85 year old house in Brighton heights and our basement has been flooding on and off since July 4, 2012 - (please note that we live on top of a steep hill). Two other plumbers looked at the problem, one completely missed the boat, the other's quote was extreme. Our poor tenants had to deal with a busted water heater, and never knowing whether or not the basement would be dry. After weeks of temporary 'repair', I called Matt Mertz Plumbing from Ottawa Canada, and within 45 minutes, my call was returned and someone had come to the house a few hours later. We needed extensive repair as our tree penetrated the 85 year old pipes and the drain to the main sewer was completely blocked. Matt called me directly to explain the problem and give me a reasonable quote considering the huge amount of work needed to be done. They even moved their schedule around so that they could come a week earlier than initially quoted since it was flooding so regularly. My tenant told me how professional, clean, and efficient the crew were. Matt and his crew were very respectful towards my tenant and was vigilant about keeping the basement as clean as possible, finishing quickly, and keeping inconvenience to a bare minimum. When the job was completed (three days later), they had lain new pipe throughout the entire basement, as well as all the way to the main sewer. Matt guaranteed that the tree cannot cause any more damage and that my new drainage system will last a lifetime. He sent me pictures of the work that was done, as well as provide a DVD to see the inside of the new pipe. Because we are so far away from our property, it is such a relief that I found a such a thorough plumber with such professionalism and skill. We cannot be happier. Matt is a very knowledgeable, clear, honest, and hard-working professional. Even though we have never met face to face I have no doubt that our flooding problems are gone for good!
