"Rightway Waterproofing is the company you want to come and waterproof your basement. I had initially set up a job looking for pros through Angie's List. I was contacted by Rightway Waterproofing via phone and email but did not respond as life happens. Well it rained really heavy again in August and I had more water in the basement. I reached out to them on a Friday and Albert contacted me immediately. They were able to come out on Monday to look at my property. Jake was thorough and friendly. He let me know what he thought we needed, explained everything thoroughly and gave us a quote which was completely reasonable. We accepted the bid and work was to commence on Thurs as they had an opening. Work was completed in one day. The area was kept pristine and they did an amazing job. The crew was courteous to my family. I could not recommend them more. I hope to have them out again at some point to finish my basement area as well. Try to keep in mind that during the season of covid many families are looking for ways to make more space in their homes or to have to home projects done. If you are waiting for work to be done just know that it is worth it! Thanks Rightway!!!"

"These guys really are professionals. They thoroughly cleaned and edged every portion of my 140' two part driveway, filled all the cracks, then coated it with no splashed sealer to be found anywhere it shouldn't have been. Staked off a nice barricade to the entrance too. Was very pleased with their service."

"We needed to have our antiquated and failing sewer main replaced, a big job. I would rate 10 stars if I could! I could not be more pleased with the service and the outcome. Bill came out quickly and provided an extremely competitive estimate. They started the following weekday. They arranged for all utility markings and permit, and handled all of the interactions with the utilities and township. They were able to maneuver the new PVC pipe around trees on our lawn so none had to be removed. The work was completed in 3 days total. It would have been completed in 2 days, but one of the utilities did not mark their lines correctly resulting in more work for them, and the township inspector arrived extremely late which delayed them in filling the trench. They worked past 8 pm on two of the days. They came back late one day to clear water that flowed into the trench after a heavy rain. Extremely professional. Super friendly service, and excellent communication throughout the project. They specialize in sewer mains and underground plumbing, and have seen it all. This is one of the best experiences I have ever had with a contractor!"

"Dan was professional, patient and really looked over the job thoroughly.  His estimate was well-prepared and he took into account that I wanted to try to do some work myself to save money.  Unfortunately, I went with someone else because I had a very limited budget and the other contractor was lower in cost.  I believe working with him would have been a more positive experience though and woudl definitely call him for a future project.

"How Did It go? Saed and his team built us a new garage from the ground up. They handled everything from drawings, permitting, to pouring the slab and framing the garage. They were very responsive to our requests and were very professional. I will definitely recommend them to our friends."

FAQs for excavation projects in Trenton, 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.
