Sewer Line Repair in New Hampshire
Of the 436,947 occupied homes we cover in New Hampshire, about 256,803 sit in towns whose typical home predates 1980 — laid before solvent-welded plastic became the default. We route calls in 127 towns here.
In short
Pre-1980 housing means clay, bituminized fiber or cast iron under the garden rather than plastic, and in New Hampshire that describes about 256,803 of the 436,947 covered homes. Only a camera survey settles which of the three is actually there.

Checking a credential in New Hampshire
The authority is the New Hampshire Office of Professional Licensure and Certification, Mechanical Safety and Licensing Board. New Hampshire licenses plumbers but publishes no online licensee search, so verification means contacting the office directly.
Before anybody excavates.A camera survey is a different instruction from a repair, and the order matters. Tell us what the drain is doing and we will route you to somebody who covers your area. No charge to you, ever. Anything else the plumbing is doing can be raised on that call too.
