"I needed to stabilize a slope. Norberto presented a plan for a retaining wall and drainage that was both functional and attractive. He provided a detailed bid for labor and materials that was competitive with several other companies He and his crew completed the job efficiently while taking care not to damage existing shrubbery and ornamentals. Norberto is professional and easy to work with. He was very good about coordinating with me. I have and will continue to use his company for other projects."

"Gary and his crew worked very quickly and efficiently on a challenging demolition job that required a great deal of precision. They also did a drain field for my septic system and both projects were completed in 2 days. His crew were hard working, polite and left the job site swept, picked up and very clean. Gary is a pro! No contractor drama. He showed up on time and got right to work. I highly recommend Gaston Brothers Excavating."

"Randy, from Universal Landscape, arrived when he said he would and finished the job a day earlier than planned. Work went like clockwork. Cleaned up nicely after each day and when job was completed. My wife and I were extremely impressed with their work and professionalism. Also, Randy was able to bring cost in below original estimate."

"They came out to give me an estimate on the work I requested. They were prompt, professional and honest. Gave me a free roof inspection. Told my roof was in great shape and that I didn't need the cleaning that I thought I was going to need. Gave me some tips and advise on what I could do myself to keep my roof in great shape. They even cleaned the small area on my siding that needed it free of charge. Would definitely recommend these guys and when I do need some roof work done these will be the guys I call."

Excavating questions, answered by experts

To locate an underground downspout, you should start by identifying where the above ground gutter drains. Look for an entry point, such as a pipe or elbow leading into the ground. Follow the surface path for signs like depressions, landscaping disruptions, or wet areas after rain. You can use a metal detector or plumber’s snake to trace the pipe underground. For deeper pipes, a professional locator tool or camera inspection may be necessary. Visual markers or utility maps can also guide the search.

The best method for digging a trench depends on the scope of the project. For a short, shallow trench (less than 2 feet deep) in light, soft soil, digging by hand may be sufficient. However, digging by hand is labor-intensive, so consider the effort required. A machine trencher is the better option for longer trenches (over 100 feet), deeper ones, or when dealing with difficult soil conditions, such as rocky or hard ground, or obstructions like tree roots. A machine can save significant time and energy in these situations.

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.

A joint utility trench, or joint trench, is a long, buried ditch on a property that contains two or more utility lines rather than running the lines in multiple trenches. Some utilities, like gas and electric or electric and communication lines, are better suited to joint trenching, while others, like water and sewer, are not allowed to be in the same trench.

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.
