Sewer Back-Ups

If a sanitary sewer backs up into your home or building, contact us. We will check out the problem. If the city sewer line is blocked, we will open the line at no cost to you. If the obstruction is in the lateral or home plumbing, you will have to have the line checked and cleared or repaired by a plumber at your cost. The responding crew will notify the homeowner if it is a city line problem (ours) or a lateral problem (homeowner).
