"I can’t say enough good things about Northern Edge Land Maintenance. I had a section of my property that was completely overgrown and unusable. There was brush, small trees, uneven ground, the whole nine yards. The owner, Derek, came in with all the right equipment and absolutely transformed it. He was professional, showed up when he said he would, and actually listened to what I wanted. The forestry mulching made a HUGE difference, and he even helped smooth out a rough section of my driveway that was washed out by the rain while he was here. It’s rare to find someone that works hard, communicates well, and clearly takes pride in what they do. I’ll definitely be calling him again for future projects. If you’re on the fence, don’t be. This company is the real deal!"

Excavating questions, answered by experts

To determine whether your homeowners' insurance will cover crawl space repair, consider the cause of the issue. Repair may be covered if the problems were caused by an event that the insurance covers, such as vandalism or a windstorm. However, companies won't cover the repair if the issues are caused by neglect or wear and tear.

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. 

The physical constraints of hand-drilling a well limit the depth you can achieve. Manually digging with picks and shovels may only lead to shallow wells of up to 60 feet in depth. To reach greater depths, you need more specialized equipment. The diameter of your well and the tools you’re using will determine how far down you can dig.

Most residential basements are 8 to 10 feet deep. You can dig deeper depending on building codes, but it does become more difficult. You’ll likely need to install stronger foundation walls and additional supports to handle the increased load. Depending on the water table, you may also need a water management system. Clay soil can support a deeper foundation than sandy soil. A structural engineer will be able to tell you the maximum, feasible depth.

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.
