Roy and Nolan ( father and son) did the job. Their price was 30% less than other company bidding for the job. They were honest and pleasant person to work with. No frills no drama, no run down of added cost: believe me: some of the well drilling company may give low price bid and by the time job is done, they will add more stating that they had to drill through rock. Now after three years I applied to build new house and granny unit. I called them to do some dry well test and they were here in my property taking care of well test within no time. Such a sweet and kind people. I highly recommend.

They drilled exactly where I wanted them to drill, got 60gpm +/-, at a decent depth. They were very careful with the run offs with good communication and they left the place very clean. Sure we had to wait in line to get started, like everybody else, but a lot of the wait was waiting for the Napa county permit. No surprise in the price, we got charged what we were told. Highly recommend the company.

The next morning I called and left a message for their emergency parts. The emergency parts employee called me back about an hour later, telling me he had the parts but could not sell them to me on off-hours. What is the point of an emergency parts line if you will not help people with an emergency? I had to drive an hour and a half to get the parts I needed. I like to support local businesses, but with customer service like this, I will take my business elsewhere.

This guy is no joke! I was/am completely ignorant when it comes to wells and well installations and personally didn't care to know but Will went out of his way not only to make sure I was informed and educated every step of the process but was completely transparent with cost. This was an experience I wish I could project upon all of my engagements with service professionals.

I hung up the phone with lots of optimism. It's been two weeks and no phone call. What is going on with the local drill companies? Is there that much business they don't care about $20k jobs? Another disappointment!

Sher E. has described our encounter with Gary and Clear Heart Drilling very well…read more Our proposed well site (in 2018) was difficult to access and with Gary's explanations and Clear Heart's equipment, the job was performed very easily. The crew was very careful of their surroundings, such as our trees, and the only thing they left was an area of drilling spoils which is now starting to be reclaimed by Mother Nature. There was a small cosmetic problem with the installation that Gary quickly offered to fix. I ended up fixing it myself with his help and our new well looks and performs as well as we had hoped. We recommend Clear Heart Drilling with no reservation.

As for the delays, since my job was not an emergency and Josh was getting overwhelmed with high urgency requests, it made it difficult to schedule me in without the fear of having to postpone me. I just would have appreciated knowing why I wasn't hearing from him. He did own up to his lack of communication on the scheduling. I deducted 1 star from the rating because of the communication issues and hope it's an isolated occurrence. I recommend him and will contact him should I require his services.
