Use ranges, then demand specifics
Cleaning and camera inspection are usually the lower-cost diagnostic steps. Spot repairs can become several thousand dollars. Full replacement or complicated trenchless work can become a five-figure decision, especially with depth, pavement, restoration, traffic, or long runs.
Any quote over a few thousand dollars should explain the defect, footage, depth, access, permit/restoration responsibility, and what is not included.
When to treat a sewer problem as urgent
If sewage is coming up through a basement floor drain, shower, tub, or toilet, stop using water in the home and get help quickly. Do not run laundry, dishwashers, showers, or extra toilet flushes until the blockage is understood.
If one sink or toilet is slow, it may be a fixture or branch drain. If several fixtures are slow, the lowest drain backs up first, or sewage appears at a basement fixture, the main sewer line is more likely involved.
What to ask before approving expensive work
Ask whether the contractor has camera evidence, where the defect is located, what pipe material is involved, whether cleaning alone is enough, and whether the recommendation is repair, replacement, lining, pipe bursting, or excavation.
For a large quote, ask for a written scope showing access points, footage, depth, restoration, permits, warranty, and what would make the price change once work starts.
