"We had water damage in a room when we were out of town. I hired Joseph and Sons to do the repairs because the pricing was fair. He showed up on time, communicated well and was easy to work with. Angelo worked with me on getting information to my insurance company and found solutions to some ongoing issues we found as the demo started. He also did exterior waterproofing repairs to ensure future water issues would not happen. I had a few extra small requests and he did not nickel and dime us. His workers were very professional and cleaned up at the end of each day. We are very happy with the work and will use on future project."

"David from ADR helped me find a company that does GPR before I spent money with ADR. He had integrity and honesty. I would definitely have used ADR had a tank needed to be excavated. It turned out that the GPR proved there was no tank. David was extremely helpful."

"C3 was not the lowest cost, but they were the best. Josh and his team were punctual, worked all day, needed no supervision and did high-quality work. Josh provided some options for a better appearance and was fair in extra costs coming from excavating the slope. We are very happy with the wall and steps and even yard for summer entertaining. I recommend C3 and Josh for any hardscaping work."

"George responded right away via Angie?s text and then a phone call. Came out the next day to attempt to snake two clogged tubs on second floor of a side-by-side two family home, connected to one sewer line.. Clog was more severe than expected. Came back next day with partner to find pipe where they join but it was behind kitchen cabinet of both homes. Decided to bypass existing line and run new lines from each tub, join them and then drop a sngle pipe to the basement and reconnect to near the main drain. George and his team were professional and communicated in a timely manner. Cleaned up and covered opening with plastic and suggested not to close wall for a week and inspect for any leaks. No leaks so far. Closing walls this weekend. Offered us a great price and an unbeatable 12 month payment plan. Thank you George and team."

"I found a surprise abandoned UST when excavating my front yard for a carport. After spending weeks online researching, reading horror stories, and becoming more panicked and confused I narrowed prospective candidates down to 4 companies and began the vetting process. I spoke with Shelley at Alternative Petroleum and immediately clicked with her. She answered all of my preliminary questions, clearing up some fact vs. fiction I had read online, and had a confidence in her manner was very reassuring. I didn't wait to get all estimates because I made my decision to go with Alternative Petroleum after our conversation. Was I ever right! Maria, Shelly, Dominique and Sal were very responsive in answering all of my questions and explaining the process in detail. They returned my calls right away and always exhibited patience and a bit of much-appreciated stress-relieving humor. Sal was on-site at 8am with his crew - all very professional, respectful, hard working guys - and they quickly got the tank pulled from my extremely tight space without damaging anything (retaining wall and paved walkway). My neighbors even commented on how clean and efficient they were. This is a family-owned business and you get the feeling they really like working together and enjoy what they do. Sal's phone never stopped ringing and I can see why. Each person involved with the business is extremely knowledgeable, honest, and professional. I had encountered so much conflicting information online and from the different companies I spoke with that I was braced for the process to be a nightmare. Thanks to Sal and Company I was wrong! I'm incredibly grateful I found them. I can recommend Alternative Petroleum without hesitation, they are THE BEST!!!"

"Sterling worked with my wife and I to get an above ground oil tank removed which had been left from the previous owner. They were willing to work with us to find an appropriate time and were able to remove the tank with an inspection from the town within 4 hours. Kudos to Nick and the team at Sterling!"

"We got multiple bids for this job and besides being the most economical they did an incredible job in a very timely manner. I highly recommend them if you need to have an underground oil tank removed. I was always kept aware of the progress of our project and Roseanne who I dealt with could not have been more professional, straight forward, and courteous."

FAQs for excavation projects in Dover, NJ

Depth depends on the type of installation and the regulations in your area. Water supply lines typically require 24 inches, while drainage pipes are often installed 36 inches below grade. For most general projects, a depth of 12 to 24 inches and a width of about eight inches is sufficient. Sticking to these specs keeps your utilities safe, code-compliant, and easier to maintain later.

When you need to run utilities underground, you’ve got two main options: boring or trenching. Boring employs directional drilling to install utilities without exposing a continuous channel, while trenching requires excavating an open channel to place utilities securely. Directional drilling preserves landscape integrity, whereas trenching provides direct access for installation, albeit with greater surface disruption. This clear comparison helps you select the method best suited to your project.

Plan on 12 hours to dig 100 linear feet when the soil is cooperative and you can work continuously. This timeframe applies when work is performed consistently and methodically. Factors such as rocky soil, tree roots, obstructions, and frozen ground increase the overall duration, demanding extra planning and effort. Comprehensive operational planning ensures that every challenge is managed efficiently and the project is completed on schedule.

If you want your yard to look untouched, laying fresh sod over the trench is the quickest fix. New sod needs 30 to 45 days to root and blend with the rest of your lawn. A local sod pro can provide you with a firm timeline and tips to ensure the grass takes hold and maintains your curb appeal.
