A co-worker referred me to Beall's to get a competing bid after another contractor orally quoted me a bid of $3,800 to $4,900 depending on how we wanted to fix the problem. I called Beall's and they diagnosed and repaired the problem for the cost of a camera down the line ($215) and $142.23.
Put another way, they saved Christmas by saving us more than $3,400. Based on this experience, I am comfortable abandoning my three bid requirement for all home repairs when it comes to plumbing issues and will start and end with a call to Beall.
