How to Choose a Contractor

  • Verify license and insurance. Confirm the contractor carries current liability insurance and any license your state requires before work begins.
  • Check references and reviews. Ask for recent local references and read independent reviews, not just testimonials on the company site.
  • Get written estimates. Collect at least three written, itemized estimates so you can compare scope and price on equal terms.
  • Confirm warranties in writing. Ask what the workmanship and material warranties cover, and whether the warranty is transferable.
  • Avoid large upfront deposits. Be cautious of any contractor demanding full payment before work starts. Tie payments to milestones.

Frequently Asked Questions

How much does excavation cost in Maine and New Hampshire?

Excavation projects in Maine and New Hampshire typically range from $1,500 for small grading to $12,000 or more for full site preparation for a new home foundation, according to HomeAdvisor and Angi regional figures. Ledge rock and boulders are the most common reason projects exceed the initial estimate.

Do I need a permit for excavation in Maine or New Hampshire?

Usually yes for anything involving foundations, septic systems, utility work, or grading that alters site drainage. Permit requirements are set at the municipal level in both states. Your contractor should obtain the permits and should be familiar with local requirements before work begins.

What happens if the crew hits ledge?

Ledge rock is common throughout Maine and New Hampshire due to glacial geology. When encountered, work slows significantly and may require specialized equipment or blasting. Reputable contractors either build a contingency rate into their quote or include a clear per-foot ledge rate in the contract. Ask how ledge will be billed before signing anything.

What is the difference between cut and fill?

Cut removes soil to lower a grade or reach a target elevation. Fill adds and compacts soil to raise a grade. Most site preparation involves both: cutting high points and filling low points to reach the engineered elevation. A well-balanced job minimizes soil hauled away, which reduces cost.

Do I need to call 811 before excavation?

Yes, always. Call 811 before any digging to have underground utilities located and marked. It is free, takes a few business days, and is legally required in both Maine and New Hampshire. Your contractor should also call 811, but confirming it happened before work begins is your responsibility too.
