"Had the opportunity to experience Lilco's work on several projects. These guys always had a professional attitude and took the time for all preparations and quality control. They did not leave a mess or unwarranted damages like so many fly-by-night contractors tend to do. They even magnet swept driveways for screws/nails whenever they finished loading out for the night. The owner is always up front about any costs, with no hidden charges to get the jobs done."

"They paved my huge driveway in only two days and the outcome is excellent. Franklin arrived with a whole team of men and they worked very hard and did a quality job. I can totally recommend Villa and Sons and I will hire them again for another job in the spring."

Excavating FAQs, answered by experts

There are several different factors that influence how long it takes to excavate. For a foundation, it could take anywhere from three days to three weeks. It can take even longer if you face weather-related delays or an inaccessible site that’s riddled with boulders and rough terrain. It may also take longer if you have clay soil, which is more difficult to dig.

There are many ways to cut through roots when digging, especially if your trencher doesn’t seem to be removing the roots. First, use a shovel to expose the roots. Then, use gardening shears to clear out smaller roots or a reciprocating saw to remove larger plant roots. If you plan on keeping the plant, avoid cutting any roots over 2 inches thick.

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.

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. 

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.
