Excavating FAQs, answered by experts

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.

After you successfully remove your boulder, you have a few options for what to do to get rid of it. You can rent a dumpster if your yard has many boulders or if you’re planning a larger project. You can even save the boulder and reuse it elsewhere on your property to save on landscaping costs. A few ideas include using the boulder as a natural, abstract statue, breaking it into smaller pieces to line your garden bed, or offering it to a landscaping company that could reuse it for another project.

A perc test can take anywhere from one to eight hours to complete. The total time depends on factors like the amount of excavation required, the depth and width of the holes, and whether multiple test holes are needed. For a single hole, the process of filling it with water and monitoring the drainage rate usually takes less than an hour. Professionals can often complete the entire test in a single day. While it's possible to get results the same day, some companies may take a few days to provide the official report.

Downspouts should be buried at least 5 to 10 feet away from your foundation. This can vary depending on your local building codes, soil type, and property slope. The main goal is to ensure water is directed away from your foundation.

To drill a shallow well, you may be able to use a drive well point. This is a tapered point that is driven into the ground. A drill bit at the end of PVC pipe may be another option to consider. A lot of the cost depends on what tools are available near you.
