A sewer replacement is a significant project. A good proposal should explain why replacement is needed, why the method fits your property, and what the work does and does not include. These questions help you get that information clearly.
FIELD NOTE
About The Need For Replacement
Ask what the camera inspection showed and whether you can see the footage. A single backup does not prove a line must be replaced; widespread breaks, collapse, or failing pipe along the route should be what supports it.
Ask whether a spot repair or lining was considered, and why it was or was not suitable for your line.
FIELD NOTE
About The Method
Ask where the entry and receiving pits would be, how deep they are expected to be, and whether any other access is needed at connections. Ask what pipe will be pulled in.
Ask how nearby utilities will be located and protected, and what happens if site conditions turn out to be unsuitable once work begins. Trenchless is not right for every line, and excavation may still be the better choice for part of the route.
FIELD NOTE
About Scope And Paperwork
Ask whether a permit is required by the local building authority and who handles it. Ask what is included for restoring the pit areas, and what surface work, such as concrete or landscaping, would be separate.
Ask how the new line will be checked after installation and whether you will receive a record of the finished work. Clear answers to these questions make it easier to compare proposals fairly.
