"Provider was prompt, professional and friendly.  Arrived at the agreed upon time for a free estimate and performed work same-day after we agreed to the price.  He stuck to the price despite taking longer than expected and more work than usual due to worn-rusted pipes in my home.  Cleaned-up after himself and left no sign that work was done other than our new, working toilets.  We are very pleased and reccomend McDonagh & Sons Plumbing & Sewer Inc.

Excavating FAQs, answered by experts

Errors in site preparation can lead to structural failures or appear costly midway. Professionals ensure detailed, reliable home base development layouts.

Preparation involves site assessment, clearing debris, grading surfaces, and compacting soil to support stable construction.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

Most states do not require excavation companies to hold specific licenses, but many require at least a contractor’s license. Additionally, heavy equipment operators require a special commercial equipment license to operate machinery required for excavation. You can use Angi’s contractor licensing tool to confirm that an excavation company you’re considering hiring is fully licensed. You should also make sure that the excavation team is fully insured before allowing them to work on your property.

Excavation is priced in cubic yards, so you’ll need to find the volume of the area in order to calculate costs. Multiply the length, width, and proposed depth of your excavation site, then convert it into yards to get the volume. Multiply this figure by the price per cubic yard.

Most homeowners can measure by hand to get a rough estimate, even if it’s tedious. You may want to pull out a tape measure or use a string to help mark the area.
