I was a bit apprehensive to have roto-rooter plumbers come over and do the work, but after exhausting all of my other options and over priced plumber in Long Island, Nassau County, I decided to call roto-rooter, after all it didn't hurt to get an estimate. The roto-rooter staff exceeded my expectations. The dispatcher called me in the morning and tried to get a professional plumber to my place at a decent time (by 9:30am - awesome). The licensed plumber who came over from the Farmingdale, N.Y. office in Long Island, introduced himself ""Luis"" - tech #51. Luis was up front about the cost and explained everything to me up front. Luis quickly and accurately isolated the problem area (old/rusted pipe). He did a thorough inspection to ensure there were no other problem areas with the pipes. He gave me a decent quote (less than other quotes received by other licensed plumbers in Long Island). Luis understood that I had a tight budget. He provided the best long term solution for my problems. He spared no expense when it came to the quality of work. He spent time (over 5 1/2 hours) to ensure the work was done properly. He tried to find the best solution in order to avoid ripping all of my walls (with my permission, he had to make a small hole to resolve the issue). He triple checked his work and made sure he left without any leaks with the pipes. He thoroughly cleaned any debris, offered a non-intrusive product to protect the pipes (no pressure, my choice), and explained that ALL work is GUARANTEED for 1 YEAR -- any issues he (Luis) will come and fix it for FREE. Luis did an excellent job and exceeded my expectations. If I, or any of my friends ever encounter any plumbing issues, I will definitely tell them to call roto-rooter and ask for Luis. I am sure all the other roto-rooter employees do just as good of a job, but with my experience with Luis, I am sold and will be a life long customer. I cannot speak for anyone else, but the only advice I can give (based on my experience) is to call for yourself and have a roto-rooter technician come over and provide you with an estimate. I am GLAD I did!!!
