About earthwork contractors in Longmont
Excavation dominates the Longmont list: 18 of the 20 contractors show it, with demolition (5) and concrete & foundations (4) behind it. Bin There Dump That leads the list on Google at 5.0 stars from 624 reviews; across all 14 rated listings the average is 4.5, and 10 sit at 4.5 or higher. 3 of the 20 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 Longmont 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 Longmont: questions
How much does excavation cost in Longmont?
Excavation in Longmont 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 CO permit and dig-safe process adds. Call two or three of the 20 contractors above and describe the same scope to each, or the numbers will not be comparable.
Can one contractor in Longmont clear, grade and dig?
Yes, and it is usually the cheaper route because you are not paying for a second mobilization. Nixcavating, Inc. covers 5 of the earthwork trades on our records, the widest in Longmont: excavation, septic systems, demolition and trenching & utilities. Use the filters above to stack the trades your job needs and see who covers all of them.
Which Longmont contractors install septic systems?
1 of the Longmont 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.

Bin There Dump That is the highest-rated earthwork contractor in our Longmont list, at 5.0 stars from 624 Google reviews. Of the 20 contractors working Longmont, 10 are rated 4.5 stars or higher (the list averages 4.5).
