What This Means for Your Home Earth Driller, Water Well Business

The good news: Washington's $267 fee is below the $369 national average. The real investment is time, not money.
Once licensed, Washington offers advantages: keep in mind the 6.5% sales tax on services. Plus, LLC formation is just $200. Your total non-training startup can be under $1,000.
