"I highly recommend DES! I arranged a consultation after a home inspection report indicated that there was moisture in our basement walls. I was worried that costly mitigation efforts would be required. A friend who had previously used DES for a basement water problem highly recommend them, telling us that they were an honest company that only does what is necessary to solve a problem. Happily, Mark Fine from DES inspected both our basement and our exterior grounds and reported that there was no indication of cracks in the foundation or water intrusion, and that no work needed to be done. It is so refreshing to have a company that doesn't try to sell expensive services when they are not necessary!"

Woodbridge Plumbing Inc has been in business since Tom and Anne Kreutzer started it in 1973 in the basement of a house on Occoquan Road with just one plumber, Tom. After three years Tom hired his first employee, David McCullen, who stayed with him until Tom and Anne sold the business in October, 2006. As the business grew, it moved first to a rented space at Canfield Industrial Park for nine years, and then to the current office and warehouse in Telegraph Road Business Park in January, 1987, across Telegraph Road from the back of Target.

"AV was extremely helpful, put in the time to get everything right. And when I had a further question after the repairs, he called me back promptly. The office staff also has been unfailingly helpful and responsive."

"We used Premium Drainage & Erosion Solutions for a large backyard project, including the installation of french drains, new gutters and downspouts, regrading a big portion of the backyard to make it more usable, and the installation of a new paver patio. We are highly satisfied with the entire project - from initial estimate to final signoff, Adrian and his team were professional, prompt, and communicative.

Excavating questions, answered by experts

Because decomposed granite is a durable material, a crushed rock or gravel base is optional as long as the DG is properly installed and compacted. However, installing a base is a good idea because it will ensure proper drainage and stability and act as a weed suppressant (although you may still occasionally have to pull weeds). Installing an adequate base can also increase the durability of driveways and walkways. If you forego the paver base or gravel underneath, line the area with landscaping fabric to avoid weeds.

Call 811 to locate and mark the gas lines at least three days before digging. In many areas, you can dig within 18 inches of the lines, though in some locations, the distance may be further. Check local regulations, as you may need a utility company representative onsite when digging. Document your calls to 811 and precautions taken to avoid gas lines. A homeowner can be held liable for hitting a gas line in some cases, but contacting the proper authorities and following all guidelines can offer protection.

The depth of a septic tank’s drain lines is between 18 and 36 inches underground. These pipes are filled with perforations and surrounded by sand, gravel, or a combination of both, as both materials help filter wastewater. While some pipes are buried closer to the surface, this can create problems unless the soil is compact and doesn’t shift much. 

Trenching is not the same as boring. Boring uses a drill to make a tunnel for underground utilities, but trenching involves digging with an excavator, trencher, backhoe, or shovel. Boring is more precise and expensive, and it’s best for installing utilities underneath buildings, roads, and bodies of water. Trenching is simpler but can cause more disruption to landscaping and ecosystems.

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.
