"I hired Pro Landscapes to demolish and remove an old shed in my backyard that was rotting and falling apart. Once I contacted them, the owner of the company reached out very quickly and set up an appointment to come and look at the shed. He was friendly and honest, he offered me the cheapest way possible to get the work done, he actually told me the more expensive job I had in mind probably wasn't the way to go, very honest. I am very happy with the work David's company did, they were fast, professional, and kind. And they even hauled away some trash for me that was not in the contract. I'd highly recommend this company for any yard or demolition projects, they will figure out a way to make the price fit the job. Thanks again!"

"It went extremely well! They were punctual, hardworking and professional. It was necessary to dig up my neighbor's landscaping, so they were very careful to disturb only what was necessary and to restore everything to its original condition. They even replaced her broken underground downspout extension (which was draining into my basement!) without comment or additional charge. When my neighbor accused them of causing a problem, MJ was quick to respond and the team on-site made a point of apologizing to her in person. I don't think MJ caused the problem, so I was very impressed that they "went high" to investigate the matter and, as I said, apologize for the inconvenience she felt she suffered. The work they did inside to remove mold and seal the wall was thorough and neat. The gentleman doing the work cleaned up everything and took all of his equipment and trash with him. his is especially important since he was working with strong chemicals. My contact in the office was prompt to address anything I threw her way. It was easy to make payments online. Best of all - no sign of water in the basement since they were here!!"

"Our driveway was big enough for 1 car and we wanted it expanded to fit 2 cars plus have a walkway installed connecting the driveway to the main walkway leading up to the house. Tillerman Gardens was recommended to me by a friend. Jesse and his crew were wonderful to work with from start to finish. Jesse was very responsive to my request for an estimate. He patiently listened to what we wanted, asked great questions to get clarity and made some really good suggestions on things we hadn't thought of (i.e. adding river rocks to the grassy part at the edge of the driveway to ease getting in and out by the 2nd car). All the members of his crew were very nice and kept the yard looking clean at the end of each day. Work was done in the timeframe given to us. We are so happy with the end result! Attached are before and after photos. Would definitely hire them again for future projects."

"The representatives were courteous and professional completing the work within a reasonable amount of time. They quickly identified the problem and worked to resolve it to our satisfaction. The cover on the master bath outet was cracked by the contractor who either did not notice the crack or failed to mention it. Overall, I appreciated the work and would have Sam and Sons return for future electrical repairs."

Excavating FAQs, answered by experts

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

Trenching and boring are two distinct methods for installing underground utilities. Trenching involves digging a channel using equipment like an excavator, trencher, backhoe, or shovel. While it is a simpler process, it causes significant disruption to the surface, landscaping, and surrounding ecosystems.

Boring, also known as directional boring, is a less invasive alternative that uses a drill to create a tunnel for utility lines without disturbing the surface. This method is more precise and is ideal for installations that need to go underneath buildings, roads, or bodies of water. Although boring is less disruptive, it is generally more expensive than trenching.

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

Generally, a trenchless sewer line is worth the cost. If your old system needs replacement, trenchless sewer repair or replacement can save you thousands on excavation costs. Every homeowner’s situation is different, but this method is definitely worth it in a lot of cases.
