"We recently bought a house in need of work, my wife and I thought it would be a great idea to do our own projects around the house. Soon enough , we realized we had no idea how to proceed with our outdoor space. He hired Andres general construction, they provided guidance and a great customer service. We are very pleased with the outcome. I will be definitely hiring them again for future projects. Thank you Andres!"

Excavating FAQs, answered by experts

Because decomposed granite is a durable material, a crushed rock or gravel base is optional as long as the DG is properly installed and compacted. However, installing a base is a good idea because it will ensure proper drainage and stability and act as a weed suppressant (although you may still occasionally have to pull weeds). Installing an adequate base can also increase the durability of driveways and walkways. If you forego the paver base or gravel underneath, line the area with landscaping fabric to avoid weeds.

Concrete blocks are the cheapest way to base a shed. However, the space in between allows critters to go under, burrow, and even damage your shed’s frame. For a more pest-proof option, consider building a shed base with gravel or paver stones. Both options are fairly affordable and easy enough for a DIY project. For gravel, you can build a wooden frame to contain the loose material.

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.

The rules for trenching and excavation include setting up and following safety protocols, learning how to use tools and machines properly, and ensuring there is a safe exit for all workers. Keep heavy equipment and materials away from the edge of the hole or trench. Call the 811 dig line before starting any excavation or trenching project to ensure you don’t hit any electrical or gas lines.

Landscape edging is more DIYable than trenching. You can DIY your own digging projects, but proceed carefully and only with proper knowledge of the equipment and appropriate safety measures in place. Keep in mind the project's scope and estimate how long it will take you to do it on your own. While you can certainly save money by DIYing home improvement projects, you can’t exactly hide an unfinished—or worse, ruined— landscaping job from the neighbors. It’s always safer to call an excavation pro near you to get an estimate.
