Excavation in Graton: questions

How much does excavation cost in Graton?

Excavation in Graton is quoted by the job or the machine day, not off a price list. A small residential dig commonly lands between $1,500 and $5,000; what moves it is access, how far the spoil has to travel, whether you hit rock, and what the CA permit and dig-safe process adds. Call two or three of the 4 contractors above and describe the same scope to each, or the numbers will not be comparable.

Which Graton contractors install septic systems?

1 of the Graton listing carries septic installation. That is installers, not tank pumpers: we drop the pump-and-haul outfits because a new tank, drain field or leach bed is an excavation job. Septic work is permitted and usually needs a perc test before anyone digs, so start that conversation well before you want the machine on site.

Which excavation contractor in Graton is rated highest?

Demar Inc. is the highest-rated earthwork contractor in our Graton list, at 5.0 stars from 5 Google reviews. Of the 4 contractors working Graton, 1 is rated 4.5 stars or higher (the list averages 5.0).
