About earthwork contractors in Beaverton
Excavation dominates the Beaverton list: 11 of the 12 contractors show it, with demolition (3) and septic systems (2) behind it. Grant's General Contracting Inc. leads the list on Google at 5.0 stars from 1 reviews; across all 12 rated listings the average is 4.0, and 7 sit at 4.5 or higher. 2 of the 12 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. 1 runs mobile with no yard address; most directories drop those outfits, we flag them and keep them. Prices in Beaverton 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 Beaverton: questions
How much does excavation cost in Beaverton?
Excavation in Beaverton 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 OR permit and dig-safe process adds. Call two or three of the 12 contractors above and describe the same scope to each, or the numbers will not be comparable.
Can one contractor in Beaverton clear, grade and dig?
Yes, and it is usually the cheaper route because you are not paying for a second mobilization. Black Rock Underground, LLC covers 3 of the earthwork trades on our records, the widest in Beaverton: excavation, septic systems and trenching & utilities. Use the filters above to stack the trades your job needs and see who covers all of them.
Which Beaverton contractors install septic systems?
2 of the Beaverton listings carry 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 Beaverton is rated highest?
Grant's General Contracting Inc. is the highest-rated earthwork contractor in our Beaverton list, at 5.0 stars from 1 Google reviews. Of the 12 contractors working Beaverton, 7 are rated 4.5 stars or higher (the list averages 4.0).
