"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."

"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 FAQs, answered by experts

Yes, professional installations include trenching or borehole drilling required for ground loops.

The time it takes to build a pool—and dig out the area—varies based on the pool size and type. A professional excavator will take between four and eight hours to dig a pool. The process will take longer if they encounter large boulders or tree roots. Keep in mind that this is a small part of the process in the long run. You will need between eight and 12 weeks to build a pool from start to finish, including the time to apply for permits.

No, fire blight does not survive free in the soil but instead is carried through insects, animals, rain, or wind during the spring. Keep in mind that it can also spread on tools, which is why you should always disinfect them in between cuts.

Yes, you can install a trench drain if you already have concrete in your yard or garden. While it can complicate some aspects of the job and slightly run up the cost, it is doable. Residential trench drains can be easily retrofitted to outdoor areas with concrete without having to remove excessive amounts of your patio, pool area, or decorative walkways.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.
