"Awesome finish work to our tiny remote cabin! Ryan and crew installed our LVP flooring in just a few hours. He kept us up to date on the project with text and pictures, super helpful since we live in Seattle and had to work. His crew kept the construction site clean and the vendor he used for our cedar interior work was meticulous. Thanks Ryan!"

"This man did way more than the option I chose. He worked hard and do an amazing job and fixing my home after a tree fell through the roof of one of my bedrooms. I couldn’t have asked for a better job done. I’d hire him again for any other repairs or builds that I may need in the future."

Excavating questions, answered by experts

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.

Slab foundations are more affordable than crawl spaces because they require minimal excavation, as the slab sits directly on the ground or on footers that only sink a few feet into the ground. Crawl spaces require excavation of the entire footprint of the home to several feet below the surface. Not only does that mean higher labor costs, but more materials are necessary for the concrete foundation walls.

Chipmunks dig their burrows about three feet deep and up to 30 feet long. The entrances can be two inches wide or more. Chipmunks are fiercely protective of their burrows and use them to protect the nuts and seeds they gather for the long winters.

A joint utility trench, or joint trench, is a long, buried ditch on a property that contains two or more utility lines rather than running the lines in multiple trenches. Some utilities, like gas and electric or electric and communication lines, are better suited to joint trenching, while others, like water and sewer, are not allowed to be in the same trench.

Generally, a trenchless sewer line is worth the cost. If your old system needs replacement, trenchless sewer repair or replacement can save you thousands on excavation costs. Every homeowner’s situation is different, but this method is definitely worth it in a lot of cases.
