Our building had a very old sewer line leaking. We received quotes close to a 100k to replace it as it would have required opening walls etc.. We found out about the new way of lining those old sewer lines on the internet. After contacting several vendors NEPR was the best choice we ever made. They went above and beyond what we asked for and was very responsive compared to many plumbers we contacted. Did the job for fraction of what replacing those lines would have cost us with a long warranty. Highly recommend to anyone with broken or rotted sewer lines. read more
