We had been in our 1908-built house less than a year, and had big house drain problems. The basement sump was picking up a sewage smell. I flushed and cleaned the sump but the smell kept coming back. Eventually I phoned Draincom to do a camera inspection of the main drains. Tony came next day and quickly diagnosed leaks from the main drain entering the sump, and recommended several approaches to further investigate and deal with the issue. As we proceeded, more and more issues were found from a very poor DIY job about 15 years and two owners ago. Not to mention old clay pipes cracked with roots in front, old building trap, and lead water supply. So... Long story short, in 5 working days the crew renewed the whole drain system from base of the main stack to the city line in front, added a backflow valve in front of the house, and replaced the lead water supply. It was a stressful and disruptive situation but once you start this kind of work you want to know everything gets done right. Tony and the crew were good to work with, I got assistance from Draincom dealing with my insurance (received partial coverage eventually), and with the city backflow rebate application. We have a 25 yr transferable warranty on the drains, and they were out of the house in a week. It's about all you can ask for with this kind of situation. Thanks guys!
