Because the vast majority of sewer systems are located underground, they can be overlooked during a home inspection. Many inspectors don’t have the specialized knowledge or equipment to do a proper sewer line inspection. However, sewer line repairs could end up costing thousands, if not tens of thousands to repair.
Tree roots are often the cause of blocked sewer lines. They can force their way through the smallest cracks and grow quickly, blocking the line. Roots are easy to spot with a sewer scope and can be augured out for a minimal cost. Cracks and detachment can also occur, usually from settling, inferior pipe materials, or just poor installation.
Costs vary dramatically depending on the problem. Simple snaking to clear a clog can run as little as $100, while hydro jetting and scoping can run upwards of $600. Depth, length, grade level improvements (driveways and roads), and severity of damage all impact the cost of repairs. A shallow repair of a small section can be completed for $1000, while replacement of the sewer line can run from $8000 to upwards of $25,000. It's very important to consult a sewer line specialist to determine actual cost of repairs.
Sewer scopes are always a good idea but if you are buying a home with trees located in the front yard or any house older than 1975, we highly recommend a sewer scope.
