Excavating questions, answered by experts

Yes, you can excavate in the winter, but it might make the job harder. Frozen ground is harder to dig, and snow or ice can make the work site more hazardous. A contractor may need special equipment and techniques, such as ground-thawing methods, to break through frozen soil. Although winter excavation is possible, it may take longer and be more costly than excavating during warmer months.

The best type of soil to build on is a mixture of sand and clay, known as loam soil. Loam soil has the best combination of these soil types to build a foundation on. The clay particles help with water retention, so it won’t erode like sandy soil might, and the sandy particles help with drainage, so you won’t see unsafe soil expansion or have an increased risk of leaks from water sitting against your foundation.

We recommend removing the stump, and grinding is a popular way to do it. You can also dig out small stumps or stumps that have fully decayed instead of grinding them. However, don’t try using acids or fire for killing a tree stump, which is a fire hazard and illegal in many areas.

Leaving the stump alone invites eventual problems, including attracting termites, mold, and fungi.

Skunk digging looks like a series of small, cone-shaped holes on a lawn or around the perimeter of a home, porch, deck, or shed. The holes that skunks dig when searching for grubs tend to be no more than four inches in diameter and may be up to four inches deep.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.
