"RK Boswell and Septic and Excavating is an awesome company. The only reason we did not hire them is because we did not have a septic pump we have an electric pump. We are new to living in a rural area and was not sure what we had. They came out, look over our system and told us exactly what we could do at no cost. Their customer service is awesome. If someone does this for us without securing a contract, I think you can trust them with the septic projects that you have."

"They responded quickly and fixed the pipe. The work was fine but a little expensive. My only reservation was price, but it has been a while, so I don't feel I can answer other questions about the company with a lot of confidence."

"Mr. Lee was easy to work with. He knew exactly what was needed to get the job done after looking at what he was working with. I needed to have a new shower drain and 2 inch PVC pipe installed after I removed the previous 15 year old leaking drain. I knew the next steps needed to be done by a professional. Glad to have found him and his expertise. I would definitely recommend this service."

"Kelly was very responsive and fixed the problem right away. I have a rental property, and Kelly was able to perform the work without me being there. Kelly sent me photos of what they found in the drain, and they emailed me the work order & invoice. I will use them again in the future if I have a plumbing need!"

Excavating questions, answered by experts

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.

Landscape edging is more DIYable than trenching. You can DIY your own digging projects, but proceed carefully and only with proper knowledge of the equipment and appropriate safety measures in place. Keep in mind the project's scope and estimate how long it will take you to do it on your own. While you can certainly save money by DIYing home improvement projects, you can’t exactly hide an unfinished—or worse, ruined— landscaping job from the neighbors. It’s always safer to call an excavation pro near you to get an estimate.

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.

The digging depth will depend on the size of the trencher you use. Even smaller units can dig up to 4 feet deep, which is plenty for a DIY job. However, much larger trenchers can reach a depth of 18 feet and are better used by a team of pro contractors, not a single DIYer. As with all home improvement projects, use the right tool for the job and proceed with caution.

The cost to repair a crawl space runs between $1,500 and $15,000, depending on the extent of the damage. Major flooding or water repairs can cost up to $10,000 for removal and repairs. If you simply need to clean your crawl space, expect to pay between $2,000 and $6,000 for a major cleanout. Replacing a crawl space beam due to rot or damage can cost between $1,500 and $5,000, while removing and replacing damaged insulation costs between $1,000 and $4,000.
