I had a backup and the camera showed significant damage to the drain at a spot right underneath the edge of a 2-year old driveway. Armando was a big help in diagnosing the problem and showing/explaining as much as possible to me.
Walter and his crew came out to excavate and repair the problem and they were extremely professional, considerate and careful. Because the excavation had to take place half on my neighbour's lawn, half on my driveway, I was very concerned that the excavation be done with as little inconvenience to the neighbour as possible.
The hole was really about as small as it could possibly be and still leave room to repair the pipe. The excavated material was carefully contained on top of a tarp and the crew showed me the problem once they got to it, as well as the repaired drain pipe, and the new cleanouts. Once the drain was fully repaired, the material was replaced with care (good crushed stone base, soil compacted with a 'jumping jack' to minimize subsequent settling). The cleanouts were levelled at exactly the right height, with stone where the small section of driveway used to be, and topsoil over the lawn part. Even the stone edging was replaced with care. Walter even insisted on washing down the driveway of any little patches of tracked dirt so that literally the only thing you could see was the excavation spot. Armando came back to do a final camera inspection to show the drain from one end of my house right to the city sewer.
When my neighbour got home, he was amazed by how small the impact to his lawn was, how clean a job they did, and how nicely they had left the soil. He pretty much insisted I write a review.
Although I hope this is the last time I ever need any drain services, I wouldn't consider calling anyone but Drainworks in the future.
