About earthwork contractors in Big Sky
Excavation dominates the Big Sky list: 6 of the 6 contractors show it, with driveways & gravel roads (2) and septic systems (1) behind it. Cornerstone Excavation Inc. leads the list on Google at 5.0 stars from 10 reviews; across all 4 rated listings the average is 3.8, and 2 sit at 4.5 or higher. 1 of the 6 cover three or more trades. That matters when a lot has to go from raw to pad-ready: a firm that clears, grades and digs keeps the job off a second mobilization, and mobilizations are where budgets slip. Prices in Big Sky are set per job, not off a rate card, so describe one scope to two or three of these firms and compare what comes back. Every listing is compiled from public Google Maps business data (our harvest ran July 2026), and a trade we do not show is one we found no evidence of, not one the firm turns down. Updated for 2026.

Excavation in Big Sky: questions
How much does excavation cost in Big Sky?
Excavation in Big Sky 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 MT permit and dig-safe process adds. Call two or three of the 6 contractors above and describe the same scope to each, or the numbers will not be comparable.
Can one contractor in Big Sky clear, grade and dig?
Yes, and it is usually the cheaper route because you are not paying for a second mobilization. Ragland Earthworks LLC covers 6 of the earthwork trades on our records, the widest in Big Sky: excavation, septic systems, drainage & ponds and driveways & gravel roads. Use the filters above to stack the trades your job needs and see who covers all of them.
Which Big Sky contractors install septic systems?
1 of the Big Sky 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 Big Sky is rated highest?
Cornerstone Excavation Inc. is the highest-rated earthwork contractor in our Big Sky list, at 5.0 stars from 10 Google reviews. Of the 6 contractors working Big Sky, 2 are rated 4.5 stars or higher (the list averages 3.8).
