"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."

"Things went well. I had had trouble getting anyone out to do this job.  Everyone I had contacted before said it was "too small" of a job.  Speedy Concrete didn't hesitate. He even came back at 11:15 p.m. the night the concrete was poured to cover my porch, when a rainstorm came out of no where!!
Most of the cost on this project was the railing system cost. I was excited to see that a concrete truck actually delivered my concrete.  A number of other contractors said, it was so small a job, they would have to just mix it on their own.

Excavating questions, answered by experts

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.

It takes one hour to dig a 10-foot trench by hand. Use a trenching shovel with a sharp tip and a long head. Plan for more time if your soil is heavy or rocky. Consider renting a trencher if you’re digging a long or deep trench or if you have challenging soil or terrain. 

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.

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. 

While general contractors sometimes handle demolition, you can also look specifically for local demolition contractors. Demolition experts need to understand structural integrity, the equipment needed for safe demolition, and the permits required for demolition.
