We purchased a 100 year old house knowing there was much work to be done, but didn't expect a very nasty sewer backup (fortunately our basement is unfinished) 4 months after we moved in. Our plumber snaked the sewer pipes, tree roots, old clay pipes, and neglect, were the causes and our pipes required major surgery. He suggested 'pipe lining' if possible as against wide ranging excavation required to replace the pipes. We researched 'pipelining' as we had never heard of this process and contacted Ontario Pipe Lining Limited. Cameron responded immediately and a camera scoping was arranged to establish if lining was feasible and the work and costs involved. Travis contacted us and explained that this could be done and outlined the scope of the work and costs. Rob and his exceptional team arrived starting work on Tuesday and finished on Friday ... they couldn't have been more efficient, working very hard every day, and were courteous, helpful, and inconvenienced us as little as possible. We are very happy with the work carried out and highly recommend this company.
