Excavating questions, answered by experts

Tree experts don’t advise against digging through tree roots, but instead encourage caution and consultation with a local arborist to make sure you don’t damage the tree’s structure or interrupt its water or nutrient intake. An arborist can recommend specific practices when digging and help prune the roots or dig a trench for utilities with a tool that can remove soil without touching the tree’s roots.

Yes, most services include site leveling and foundation work. Confirm with your contractor for specifics.

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.

There are several different factors that influence how long it takes to excavate. For a foundation, it could take anywhere from three days to three weeks. It can take even longer if you face weather-related delays or an inaccessible site that’s riddled with boulders and rough terrain. It may also take longer if you have clay soil, which is more difficult to dig.

It’s possible to transplant trees as tall as 50 feet when an experienced tree planting service uses the right equipment. However, a tree with a trunk larger than two or three inches in diameter needs to be handled by a professional in order to yield successful transplanting results. Consulting a tree planting professional is the best way to tell if your large tree can be safely transplanted.
