As a local member of the community, I have been in the construction industry for just over 10 years. With experience ranging from general construction needs, to light electrical, and plumbing I have the knowledge it takes to complete a job on time and with excellent quality. \n\nWhy pay more for a large contractor to provide you a simple service when you can save money and have some peace of mind knowing a local member of the community is taking care of your needs and providing exactly what you need.

This is a new business, but I've been doing this type of work for about 10 years. \nI am licensed in South Dakota and am getting registered in Wyoming. \nI have experience running multiple types of construction equipment. If my skid steer with attachments and excavator won't do the job I can rent what is needed. No job is too small and always up for a challenge. \nI listen to the clients ideas and needs to insure the job is done successfully and to the clients expectations. I strive to complete a job in a timely manner and encourage the clients input during a job avoids delays.

"Totally Excellent! Jon and the Crew at ERE flattened out about a 1 acre square of my property (future building site) Perfectly! And it was a gnarly pit to start with full of boulders and old items like water heaters and car fenders as it was evidently a dump site for the neighborhood before I got here. Finished the project quickly and to my complete satisfaction, I recommend ERE to Everyone for your next Excavation project, big or small Jon can handle em All!"

Excavating FAQs, answered by experts

Because decomposed granite is a durable material, a crushed rock or gravel base is optional as long as the DG is properly installed and compacted. However, installing a base is a good idea because it will ensure proper drainage and stability and act as a weed suppressant (although you may still occasionally have to pull weeds). Installing an adequate base can also increase the durability of driveways and walkways. If you forego the paver base or gravel underneath, line the area with landscaping fabric to avoid weeds.

The rules and regulations regarding groundwater use vary between states. To find out if you can dig a well on your property, you’ll have to consult these regulations, address any compliance requirements, and get the appropriate permits. It’s also important to check that your intended location has the right geology and water table to support a well.

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.

Chipmunks dig their burrows about three feet deep and up to 30 feet long. The entrances can be two inches wide or more. Chipmunks are fiercely protective of their burrows and use them to protect the nuts and seeds they gather for the long winters.

A joint utility trench, or joint trench, is a long, buried ditch on a property that contains two or more utility lines rather than running the lines in multiple trenches. Some utilities, like gas and electric or electric and communication lines, are better suited to joint trenching, while others, like water and sewer, are not allowed to be in the same trench.
