Get a minimum of three bids. Estimates for an average-sized job should be within a few hundred dollars. Be suspicious of anything that is substantially lower or double the price of the rest, and watch out for hidden fees, like charges for travel expenses. They could be signs of a home improvement scam. A good plumber will not nickel and dime you like this, and many of us will offer free estimates.
Awesome experience with Charlie's Rooter Service! Our outside area drains were overflowing when it rained and about to flood toward the house. I called Charlie's and they had Luis come over within an hour. Luis was super friendly and ready to help when he arrived. He figured out the problem and snaked the street drain and pulled out a huge clump of roots that were clogging it up! But there was still some backup flooding on the side that he was able to isolate to get rid of the mud and debris that were clogging that up. Before leaving, Luis even gave suggestions on how to flush it out periodically to keep things flowing smoothly. Luis is the best and I would definitely use him for future plumbing problems, highly recommended!
