Moved into an older house (40 yrs old). No clue the condition of the drains or sewer back up issues, so called Roy for an inspection.
He came to our house and snaked the drains, to ensure no blockages. We found a few spots where tree roots entered the drains, and caused some paper and feces clots....so we sent the cutter down there, and cut up all them branches. LOL.
Well worth it, because its better than having crap flow back into your basement!
