"I had Ken come out to look at a stump removal and I mentioned a retaining wall project I needed to get done. Ken took some quick measurements and then came back again late that afternoon with his team and took more precise measurements. That evening I had a quote that was comprehensive and fairly priced. We quickly agreed on the project and date. Ken, Rowan and Roger showed up on time and completed the job quickly and efficiently. I would highly recommend McAdams Excavation and Landscaping for all your excavation, landscaping, and hard scaping needs. I am more than totally satisfied!!!"

"Couldn’t have asked for a more honest and trustworthy contractor. After letting my previous GC go, Mike and his team were a breath of fresh air. Extremely impressed and grateful for their work. Highly recommend. Should have called Twin Timber first."

Excavating questions, answered by experts

Consultation with the local government helps identify necessary permits, avoid project delays or legal issues, and protect project integrity.

Digging out a basement takes anywhere from a few days to a few months. Most projects take at least two to five weeks, but it could take several months if you encounter obstacles. This project takes longer if you need to brace or raise your home before the excavation. Digging out a basement in new construction can take as little as three days.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

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.

You can dig 60 to 80 linear feet by hand per day depending on the depth. Digging a 100-foot trench by hand will take you two work days, but it can take longer if you have heavy or rocky soil. If you’re digging a deep trench or one that’s over 100 feet, consider renting a mechanical trencher, such as a walk-behind or ride-on, or calling a pro for help.
