"One Stop was great through the whole process of my kitchen remodeling. They had great advice for me and kept me fully informed all the way along. I am very happy with the finished product. When I went to pick out my countertops and flooring, I could tell immediately that the One Stop people had a great reputation and working relationship with those businesses. It way first remodel experience. I hope to work with them again on the bathrooms in my house."

"Jared was who we mainly spoke with, his response time was great and was a pleasure to work with. Justin and Korbin are the two who came and cleared our lot. They were very professional and got the job done fast. I will definitely use them again for future work!"

"This was the easiest process. They checked what we wanted, made sure everyone working on it understood and the price they quoted came in under the original once they got into it. Will definitely be hiring these guys again for my next project!"

"Our landscaping was in need of significant pruning and Mike did a great job. He went the extra mile to take care of the desert landscape. He even worked on the weekend, as well as came back an unscheduled day to get the job finished. I would definitely recommend and hire again."

Excavating questions, answered by experts

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. 

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.

Yes, you can excavate in the winter, but it might make the job harder. Frozen ground is harder to dig, and snow or ice can make the work site more hazardous. A contractor may need special equipment and techniques, such as ground-thawing methods, to break through frozen soil. Although winter excavation is possible, it may take longer and be more costly than excavating during warmer months.

Some two-in-one tools and machines do both jobs, and those could be the right solution for smaller residential projects. However, the phrase “use the right tool for the job” definitely applies to digging. For the best results, get two separate tools for your trenching and landscape edging projects or call a pro to take care of everything for you.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.
