While tiling the shower, my husband dropped a dallop of grout into the shower drain in error. We tried everything but were not able to get through the grout. When Roto-Rooter came, they were not sure they could get through the grout but they did it. I found the price to be a little pricey, but the job did get done. The plumber was curteous, friendly, tidy and knowledgeable. Thank you.
