I found Doctor Rooter here on Homestars, and was impressed by the 10/10 rating, and great reviews.
Water was coming in my basement at the front of the house. Oleg and Bill were very fast to respond to my call. They diagnosed the source of the water that day, put in a temporary measure to hold back the source, and then returned the next day to begin the waterproofing work. The rest of the house was done at previous time, and it seems the water was held at bay there, but found its way to the unprotected part. I was happy to see they used Delta Brand waterproof membrane, since my research showed this to be the most reliable.
The workers were polite, and clean for the most part (as far as piles of dirt can be clean)
I am happy to recommend Doctor Rooter, and will definitely call them for future plumbing and other work. (We are thinking of lowering the basement floor. Is there anything these guys don’t do?)
