Very prompt reliable service

I was in the unenviable situation of having my sewer blocked and on the verge of overflowing. I called SL Drainage for assistance who attended the same Saturday afternoon and rectified my problem. This level of service is so rare these days. I would be more than happy to recommend this company to anyone who is in need of a reliable contractor. Thank you SL Drainage.
