Do you have a favorite plumber?
I am accepting additional estimates for a licensed plumber to obtain necessary permits, qualifications and equipment to repair a clog in 4" iron pipe about the place where it meets clay. 100 yr old house in highlands... 3ft deep and approx 5-6' long below sidewalk. Convert current downspout intake to clean-out fitting. Line has been cabled 45' and cameras have been applied from 2 access points.
