I had Roy come out to our new (old) home right after we took possession last week, to take a look at the main drain under the house and tell us what kind of shape it was in.
If you haven't called Roy yet, do. He was easy to get in touch with, and arrived on time. He charged exactly what he said he would. Also, the other contractors that he works with (namely, Viktor) are an absolute joy. Roy made some recommendations for maintaining our old clay pipes so that we don't have to undergo a costly replacement, and Viktor also gave us good advice on the general plumbing of our house, and his team will be coming back to do the rest of the plumbing of our home reno.
We couldn't be happier. Thanks, Roy!
