Cambridge has a lot of housing stock built before 1970, and that matters more than most homeowners realize. Neighbourhoods like Galt and Preston were largely built out between the 1920s and the 1960s, when clay tile was the standard material for sewer laterals running from the house to the street. Clay pipe holds up fine on its own, but the joints between sections were never sealed the way modern PVC is. Decades of soil movement and mature tree roots looking for moisture eventually work those joints open, and once a root finds a gap, it doesn't stop growing. What starts as a slow drain in one bathroom can turn into a full sewer backup a year or two later.
A plumbing camera inspection is the only way to see that happening before it becomes an emergency. We guide a waterproof camera through your line and watch the footage together, so instead of guessing whether your home has this issue, you know. If we find a cracked joint or a section that's bellied from decades of ground shift, we'll walk you through water line repair and sewer options with the video as your evidence, and you decide what happens from there.
Homes built after 1980 aren't immune either. PVC lasts a long time, but a heavy freeze-thaw cycle or a tree planted too close to the line can still cause trouble no matter what the pipe is made of.
