"I hired KJ Drywall to frame, insulate, and sheetrock/texture a basement bedroom. Kevin did a great job. He was very knowledgeable about what needed to be done. He worked very hard and completed the job in a good time. He seems pretty efficient. We had a plumbing issue during his work, and he had someone out to fix it within about 45 minutes. The repair was made in Avery professional manner. Long story short, this fellow and his help were very good to work with, very fair with the price, And Kevin seems like just a really good guy. Glad to have worked with him."

"Harlan was professional, polite, and honest. He completed everything in a timely matter, payed attention detail, worked well with all the requirements we needed to abide by, and he did everything himself! Most of the other contractors I had reached out were not willing to follow the guidelines needed. Harlan was great and does not keep you waiting! I would highly recommend him! I was very pleased and have no complaints! He goes above and beyond what you ask of him!"

Excavating questions, answered by experts

It takes one hour to dig a 10-foot trench by hand. Use a trenching shovel with a sharp tip and a long head. Plan for more time if your soil is heavy or rocky. Consider renting a trencher if you’re digging a long or deep trench or if you have challenging soil or terrain. 

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

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.

There is no standard depth for burying a septic tank; they are typically buried anywhere from 4 inches to 4 feet underground. The final depth depends on several factors, including the depth of your main sewer line, the height of the bedrock, soil type, local regulations, and the property's landscape. If you plan to grow grass or plants over the tank, a depth of at least 4 to 6 inches is recommended. Deeper tanks can be more difficult to locate, but a septic professional can help find it for you.

Excavation and grading are both generally necessary for designing your foundation, and leveling the ground where your foundation will go. These steps can also prepare the area by removing vegetation and anything else that could interfere with your home’s foundation.
