"I dealt with John and Dave. They were always very punctual, the proposal was specific it clearly stated what they would be doing, the size of the septic tank, overflow, main line and the cost. It was all done to code. They were polite, responsive and answered all my questions even after the work was completed, I wish I would have realized or been told how extensive the area that was disturbed would be. I would have removed more of the plants."

"Joe showed up when this was in the planning phase. This was to regrade the side of the house which caused flooding in the basement He guided the project planning items with his suggestions as well as accommodating me for the things that I wanted. He visited a second time when I was ready to make the final decision to hire him. The crew was polite and efficient. I would absolutely recommend him for the kind of work I had done."

"In 2010, we changed our beat-up deck to a new patio and used Napolitano Brothers for the upgrade. The patio came out better than expected and completed within 1 1/2 weeks (despite several days of rain storms). In 2016, we decided to expand our patio to include a bar/cooking area for grilling and a fire-pit to enjoy the cooler days. Without a doubt, we returned to Napolitano Brothers and they did a fabulous job. The work was seemless (as if we had the work done in 2010) and completed within about a week's time. Both jobs worked out perfectly and my wife and I highly recommend Napolitano Brothers. They have decades of experience and don't overbook jobs so they complete timely and with precision."

"

The Junk in My Trunk crew called us early on the day of the appointment to let us know when they would arrive and to confirm directions.  They showed up when they were expected and cleared out all the unwanted items in the house.  They were cooperative and cordial throughout the process, and cleared out items including mattresses, sofas and couches, and a refrigerator that was in the basement.  They filled every inch of the 12-yard truck and as a result I felt that I got very good value for the price.  I would not hesitate to use this service again or recommend them.

"I had a great experience with steve from high idle excavation. The quote was very reasonable. They ripped up my driveway and walkway due to just buying my home. It was very needed and a hazard. They paved my driveway and disposed of all the material. They had the job done in two days. I will be using them for my above ground pool next season!"

Excavating FAQs, answered by experts

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.

The average cost of excavation is approximately $3,200, with typical projects ranging from $500 to $15,000. Depending on the contractor, you may be charged between $50 and $200 per cubic yard or an hourly rate of $40 to $180 for an excavation specialist. The total cost is influenced by several factors, including the project size, the amount of soil to be removed, and the soil's condition. Hard soil, tree roots, or excessive rocks and clay can increase the price, potentially adding $200 to $1,200 to the final bill. Other factors that can drive up costs include the presence of nearby structures that complicate the work or tight spaces that require manual excavation instead of heavy machinery.

Depending on the severity of the freeze and the method used, thawing frozen underground pipes can take anywhere from 30 minutes to several hours. Applying heat directly to the pipe using heat tape, infrared lamps, or hot water jetting can speed up the process. However, patience and careful monitoring are key to avoiding pipe damage.

If you’re planning to dig on your property, you’ll need to check for underground utility lines. Call the national call-before-you-dig 811 number. Once connected to an operator, you can schedule a site visit to mark underground lines. This way, you won’t accidentally dig into pipes and can cause major (read: costly) issues.

You do not have to dig footers for a deck as long as it meets local code and holds up to weather in your area. If you live somewhere that experiences high winds and earthquakes, you may need to dig for your deck posts. Deck blocks, post anchors with base plates, and helical pile systems are the three no-dig deck post options you can choose from if local code permits.
