"I followed a lead a friend mentioned and having a water management basement drain system checked to see if any blockage going towards the sump pump. This is the 30th year of having the water management inside basement draining system. Placed a project and shortly got a call from Dun Rite Drain Cleaning. I was able to speak to an actual technician as my job is not about sewer, toilets, etc. Spoke with Sterling at Dun Rite Drain Cleaning and he gave good information and he also agreed I should contact the company that has the warranty. He did mention that the companies in general hire out the drain inspection as they do not have on staff such personnel. I was given a rough quote as FYI. After getting information I contacted the company that I have warranty with, and it was determined I did not need the service. The company with warranty had me take pictures and will get back with me after reviewing them. Gave information to the friend who suggested a camera system and he mentioned a good tool to get for my own peace of mind to check out the system and can be used for looking at other enclosures."

"I had a backed up sink,shower and toilet. A major pipe was cracking and leaking into my basement. Reme explained everything to my satisfaction and gave different suggestions. I had new pipes put in and the sewer line snaked as well as a new sump pump installed. It was all done in one day and I was kept informed throughout the process. The price was a good price for what was done and I would not hesitate to recommend Remendy Plumbing."
