Prices will very a bunch on location and obstacles.
I was hired by an Architect friend that had a couple dozen investment properties in the N Bay ,in Ca .From meter to crawl space .Everyone had a concrete sidewalk ,walkway and concrete porch .The homes were built in late 50’s to about 1961.
Some had the waste line in the same trench
Or they were stacked .Waste lines and water service lines were failing , collapsing, filled with roots etc.My complete jobs were 8k to 12K with permits .It snowballed from his jobs to neighbors ,they all wanted to keep up with the Joneses ,the could not stand to be one upped by Frank next door 😳😂.We installed sch120 , and sch.80 DWV with SS Couplings .We found some clay pipe , concrete transite and Cast iron with rope and lead filled bell ends .Roots invaded the joints .Water service were copper or Galvanized 1” .We did horizontal drill if we could .Landscaping is another obstacle 😳😡😂.Glad they are old homes with overhead power ,bout the only thing that was not in the way .
