"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

Yes, an excavation company is the best option for land grading and yard leveling. General landscapers might be able to tackle these projects, but an excavation company will do a better job because they’re used to operating the necessary heavy machinery. Landscapers might opt to do the work manually, which takes much longer and could cost you more in labor fees. Finally, excavation companies will understand local regulations and know when you need permits to legalize the work, while a landscaper might not.

You do not have to dig footers for a deck as long as it meets local code and holds up to weather in your area. If you live somewhere that experiences high winds and earthquakes, you may need to dig for your deck posts. Deck blocks, post anchors with base plates, and helical pile systems are the three no-dig deck post options you can choose from if local code permits.

Trenchers can dig holes as narrow as 4 inches or as wide as 4 feet. Check the specifications of the trencher you rent or buy to determine how wide it will cut into the landscape. Better yet, let the excavation company know how wide you’d like the trench to be, and they can help you choose the right trencher for the job (or do it for you).

Hardscaping often requires preparation of the ground in the area where the feature is being installed. This can include digging, compacting, and leveling the soil, ensuring adequate drainage, and removing any existing plants. The extent of preparation needed will depend on the type and size of the hardscaping feature being installed.

Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.
