After a sewer line back up, 3 contractors came to propose a solution. (It was the 2nd backup in 6 months.) S & D was the only one to clearly show and explain there was no line break, no roots. Analyzed likely cause of back up was lack of water flow from dual flush toilets. Other 2 contractors proposed excavating and replacing sewer line for $2.6 K and $3.6 K.
Ended up replacing toilets.
Plumber (Jess) was thorough, professional, pleasant and answered all questions with easy to understand language for the non plumber.
Highest recommendation!
