Underground Pipe Repair Boston. Underground pipe repair is significant in historic cities such as Boston. As the underground Boston pipes continue to age, roots will penetrate the joints, cracks or any missing sections of the host pipe. Many people are aware of root removal, but most people do not realize this will not solve the problem – roots will continue to grow until the pipe is sealed from beginning to end.
