Best Free Phone Estimate in Arlington TX

My initial experience was ok, while they couldn't find the cleanouts at first, they found them after they had done their work. Lines in the house were backed up. Was billed $275 for less than 30 minutes of work, and now I've left a voicemail 4 days ago and not been called back, for the exact same issue a month later. Initially they were responsive, and my issue seemed to be resolved, but it clearly was not. I guess i'd be cautious on this one.
