"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."

Small jobs welcome

"Stopped by almost immediately and Got a fair quote and was the cheapest. 2 other contractors never even showed up and one just looked at google maps to give me an estimate. It wasn’t a big job (2 car driveway), but when I was ready for the work, they showed up the next day as agreed to do the demolition and compacted stone/ gravel. They called and asked me on what day would be best for the paving and I told them asap or Thursday. They showed up first thing on Thursday and finished the job in about 2-3 hours. They then cleaned up everything and the driveway looks great! They did a fantastic job at a great and fair price! Very respectful of neighbors and my property! I would definitely use them again and I highly recommend them!!"

"Top notch service! Antonio was quick to respond to my call, he arrived on time to give us an estimate. We hired them for a spring clean, small tree removal, and trim an overgrown bush. The quote was fair, and the work exceeded my expectation. His crew worked extremely hard, and very efficiently. They went above and beyond and literally covered every inch of the property. We are going to have them continue to do our lawn care, and replant the removed tree. He already had the stump ground, and returned today to confirm our tree selection. For anyone in the area, I highly recommend Four Brothers!"

"I had an old pond in my yard that hadnâ t been maintained in 10 years. My wife and I didnâ t know what to do with it we wanted to just get rid of it. Matt and has crew came in and redid the entire project putting in a waterfall and some cool looking koi fish. My wife and I sit out there at the table next to the pond and our flower garden that they also redid every night during the summer for dinner! I highly recommend him and his company to anyone looking to redo their outdoor living space."

Customers say: Quick response

"Was struggling to find a reliable guy to do some paver work as well as a retaining wall for my backyard for the summer. I was recommended Art to come by. He was able to get a move on things quick. He had incredible attention to detail and was in constant communication with me. Gave some great advice about water drainage with the new patio and way to prevent stagnation of water. He also gave great advice on maintaining the area to ensure the longevity of the project. Overall great job and looking forward to having him do my front walkway as well!"

Excavating FAQs, answered by experts

Digging out a basement takes anywhere from a few days to a few months. Most projects take at least two to five weeks, but it could take several months if you encounter obstacles. This project takes longer if you need to brace or raise your home before the excavation. Digging out a basement in new construction can take as little as three days.

There are several methods to hollow out a tree stump, and the best one depends on your tools, experience, and priorities. Common methods include using a chisel and hammer, a chainsaw, or burning.

  • Chisel and Hammer: This is often considered the easiest approach for those with limited tools or experience, though it is the most time-consuming.

  • Chainsaw: Using a chainsaw is the fastest method, but it comes with significant safety risks, especially for inexperienced users.

  • Burning: This can be an effective method, but it is not recommended unless you can first drill holes into the stump. Without holes, the stump will be difficult to light and may not burn completely through.

A power drill with at least a ⅜-inch diameter bit can make the job quicker and easier, regardless of the primary method. While you can use a chisel or chainsaw without a drill, it will require more time and effort. Always wear protective goggles and thick gloves, as splinters are an inevitable risk.

You should dig 3 to 6 inches deep for plastic edging. Dig as wide as you need to fit your plastic edging into it—2 inches is usually sufficient.

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. 

Call 811 to locate and mark the gas lines at least three days before digging. In many areas, you can dig within 18 inches of the lines, though in some locations, the distance may be further. Check local regulations, as you may need a utility company representative onsite when digging. Document your calls to 811 and precautions taken to avoid gas lines. A homeowner can be held liable for hitting a gas line in some cases, but contacting the proper authorities and following all guidelines can offer protection.
