We've had to call the well company twice since we moved to mariposa and they are life savers. Yesterday our water went out and within a few hours Yosemite Falls Well Drilling came and fixed it. Each time they have come the same day even though they are on other jobs. This is so refreshing for a small town like mariposa to have a business you can count on, who comes quickly and resolves the problem for a reasonable price. Thank you for coming fast and helping this work from home and homeschool family out!

About a year ago, I had some work done.
They were not very professional ad frankly rude.
They completed the job and then the son of the owner left the hose running and completely emptied my 2,500 holding tank! This is NOT a good thing to do to a well and it took several days to replenish.
Called them but they did not seem to care and basically said that these types of things can happen.
I told them they needed to be more careful.
They did not apologize.
Recommend using someone else!!!!!
Called again two weeks ago about another problem and they just blew me off and kept saying they were too

We had damage from recent rain/snow storms. They came out and quickly repaired our system. Even set us up to have our water pump run through our generator since power was out. Great company with honest and reliable people.

This company was very helpful in helping me understand the process of drilling a well from start to finish. They took care of all the paperwork and permits. Also used them for my pump and storage tank. Would highly recommend.

Mark and Heath Harris are topnotch well drilling and pumping experts. Super professional, and thorough with their explanations of the different costs and options, they both made me feel comfortable right away. Call these guys if you need a well! Mark is the old(er) man and is endless funny and personable. Heath, his son, is a little more all business / task master. They got my well in within a couple weeks of contacting them. Spending money on a well may not be the most fun thing to do, but these guys made it as enjoyable as possible.

Being unfamiliar with wells and well drilling, I asked my realtor and was told that Yosemite Falls was THE company to use in the Mariposa area. Turns out that every sub-contractor I had on the project told me the same thing. Yosemite Fall's service was timely, their advice was on the mark, they were happy to let me tackle a portion of the work to save money and best of all, they chose a spot to drill that resulted in a 50 gallon per minute well. All-in-all I was very happy with their work!

This company was recommended to me for well water testing. I called them four times; left messages twice and spoke with someone twice in an attempt to set up an appointment. They NEVER called me back.
