"The job was a complete remodel from floor to ceiling. We replaced tile and carpet with engineered hardwood, gutted and remodeled 2 bathrooms, new kitchen cabinets, countertops, backsplash and appliances. Updated plumbing and electrical, removed walls, scraped popcorn ceiling added can lighting and painted. The job also included all new solid wood doors throughout, and new trim and molding. I would recommend Green Hills Construction in a heartbeat! I was kept in the loop throughout and the end result is awesome."

"The project was demolition of an old swimming pool to code and filling it in with dirt. Ray is a hard-worker, never complained about the 100+ degree weather, reliable, finished the project in the amount of time proposed, gave a fair price and made my life easy. Project required extra (unforeseen) equipment and he actually split the extra cost with us instead of making us pay the full extra amount. Would use him again and recommend him."

Excavating FAQs, answered by experts

It can take several weeks for the ground to settle after removing a tree, and the soil under larger, more mature trees can take months. The deeper the tree has been ground under the soil, the longer it will take to settle. However, this extra depth can help you plant new landscaping sooner because you’ll have more space for fresh soil.

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. 

The rules and regulations regarding groundwater use vary between states. To find out if you can dig a well on your property, you’ll have to consult these regulations, address any compliance requirements, and get the appropriate permits. It’s also important to check that your intended location has the right geology and water table to support a well.

The cost to drill a well varies, with a national average of around $5,500 for a 150-foot well. However, prices can fluctuate significantly based on several factors, including your location, the required well depth, geological conditions, local regulations, and the specific drilling methods used. For the most accurate cost assessment, it is best to research and get quotes from local well-drilling professionals in your area.

There is no standard depth for burying a septic tank; they are typically buried anywhere from 4 inches to 4 feet underground. The final depth depends on several factors, including the depth of your main sewer line, the height of the bedrock, soil type, local regulations, and the property's landscape. If you plan to grow grass or plants over the tank, a depth of at least 4 to 6 inches is recommended. Deeper tanks can be more difficult to locate, but a septic professional can help find it for you.
