I called West Michigan Sewer for a suspected bad check valve in my sewer line. They came out and verified my concern. They gave me a estimate to excavate, locate and replace the check valve and install a manual shutoff valve which to me seemed reasonable. After the work was complete they actually charged me less than the estimate due to less time spent to do the job. I feel they were very honest and professional actually lowering the estimate cost. I cant recall any contractor ever lowering the final cost after giving a estimate price for a job. I would recommend West Michigan Sewer for your sewer and septic problems
