"Vinny is a very friendly and professional guy who we really enjoyed working with. The quality of his work is excellent- we used him for our sidewalk and refurbishing the rod iron railings. Overall positive experience with him and the final project turned out great! We would definitely recommend him and will be using his services again in future projects."

"Victor was referred to us by friends and he did not disappoint. He was not the least expensive option to us but his track record speaks for itself. The planting?s and masonry his crew installed were beyond what we could have imagined. Loving my yard. Don?t hesitate to hire this company. Leo S"

Excavating questions, answered by experts

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.

Almost any kind of home can have a wine cellar or cabinet installed. You’ll need an area where a concrete floor can be put in, along with the necessary insulation, climate control, and ventilation systems. If you think of yourself as an aspiring sommelier, an underground wine cellar may be ideal, but it will cost significantly more. 

What you choose to install really depends on your budget and how many bottles you’re looking to store.

To drill a shallow well, you may be able to use a drive well point. This is a tapered point that is driven into the ground. A drill bit at the end of PVC pipe may be another option to consider. A lot of the cost depends on what tools are available near you.

If you have a broken sprinkler pipe underground, there will be some signs you can easily spot to locate it and take action. These include leaks, water spouts, flooding, consistently damp areas on your lawn, low water pressure, and grass around the sprinkler head that’s taller and darker than anywhere else in the yard. 

If there are no obvious signs of a broken pipe, you can use tools such as water leak mics, leak noise loggers, audio devices that record leaks, and acoustic testing links. 

Broken pipes can lead to uneven watering, plant damage, and higher utility bills. The longer you wait to fix them the more the repair cost may be.

The rules for trenching and excavation include setting up and following safety protocols, learning how to use tools and machines properly, and ensuring there is a safe exit for all workers. Keep heavy equipment and materials away from the edge of the hole or trench. Call the 811 dig line before starting any excavation or trenching project to ensure you don’t hit any electrical or gas lines.
