"My friend recently had some work done at his house and recommended him. I called and told him what I was looking to do and he was honest and told me how I could save money and do it myself. walked me through the process and told me who to call with the city and approximate time frames. You don't come across this type of "good people" too often these days. I highly recommend Wilber Construction. Randy will be my first call in the future for any type of construction work. Thanks Randy!"

Excavating FAQs, answered by experts

There are several methods to hollow out a tree stump, and the best one depends on your tools, experience, and priorities. Common methods include using a chisel and hammer, a chainsaw, or burning.

  • Chisel and Hammer: This is often considered the easiest approach for those with limited tools or experience, though it is the most time-consuming.

  • Chainsaw: Using a chainsaw is the fastest method, but it comes with significant safety risks, especially for inexperienced users.

  • Burning: This can be an effective method, but it is not recommended unless you can first drill holes into the stump. Without holes, the stump will be difficult to light and may not burn completely through.

A power drill with at least a ⅜-inch diameter bit can make the job quicker and easier, regardless of the primary method. While you can use a chisel or chainsaw without a drill, it will require more time and effort. Always wear protective goggles and thick gloves, as splinters are an inevitable risk.

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.

The best way to protect tree roots is to avoid the roots entirely by excavating outside the root radius of the tree. For nearby projects, it’s a good idea to construct a temporary retaining wall. But that’s not always possible, depending on the project and the root system. In these cases, consider using alternative equipment like an auger to tunnel under the ground.

Remember, tree roots can damage nearby cement foundations as they grow. If a tree is close enough to interfere with large excavations, it may be better to remove the tree than risk future problems.

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

Some two-in-one tools and machines do both jobs, and those could be the right solution for smaller residential projects. However, the phrase “use the right tool for the job” definitely applies to digging. For the best results, get two separate tools for your trenching and landscape edging projects or call a pro to take care of everything for you.
