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.

During our yearly routine service, they found a crack in our water tank causing a sizable leak. When fixing the tank, they had to work around our out of date equipment and piping. Everything is working now. Weeks pointed out that we will still need to replace our water pumps sometime in the future since the original set up is still kinda janky, but Weeks did not pressure us to do so now, and we really appreciate their honesty and their understanding of our old system and how best to help us move forward into the future. Thank you!

Highly recommend the company.

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.
