This retired couple called us for a second opinion after the first two companies said they needed a $18000 - $20000 sewer repair.
We came out and did our own sewer scope inspection and found that only 15' of pipe had any issues and the rest of the pipeline was in excellent condition.
We were able to make the repairs at a small fraction of what the other companies were trying to sell.
Beware of the "Free sewer scope" guys.
They work on commission and only get paid if they sell you a sewer repair, they are not sewer professionals, they are salesmen and they are especially aggressive with the elderly.
Remember, there's no such thing as a "free" sewer scope inspection.
