Water Well Services

Drilling, Repair, Maintenance, and More!

Well drilling:

Uh-oh. You turned the faucet on and nothing happened. If your water has stopped flowing, don't panic. Contact us anytime and we're on the way. We know how important it is to get the water flowing, so we'll work as fast we can to diagnose the problem and get the water back on. Click here for more information.

Water treatment (water purification):

Want to give your water a thumbs up?It may look clean, but a clear glass of water doesn't tell the whole story. Let us test your water and we'll show you if you need a treatment system and if you do, the right Evolve system. Click here for more information.

Pump systems:

When you're on a well system and the water stops coming through the faucet it isn't always the well. It can also be the pump.Before you panic, you may not need a whole new pump system. Click here for more information.


Hydro-fracking, sometimes called hydrofracturing, is a well development process that increases the flow of water from a bed rock well by increasing the size and extent of the bedrock fractures that bring water into the well. Click here for more information.


Geothermal is here today and it's changing the way residents and business owners in New Hampshire are heating and cooling their homes and businesses. This is the renewable, affordable heating and cooling source you have wanted. Click here for more information.

  • George Craggy

    Jonathan, I wanted to drop a couple of lines to tell you how satisfied and happy that I chose Capital Well Co. for my water needs. From your lead man Steve to your drill people, your plumbing guy and your guy on the back hoe. Everyone that cast a shadow on my door threshold were polite, professional and willing to take the time to explain and answer my questions; which were many . Jon, it was my pleasure to meet you today and pleased that you came by for a follow up visit and explain how the heater works. SO...if I get a chance to tell everyone that needs a new well, I definitely will. It is apparent there is no "I" in your team . Thank you everyone.
  • Richard Meaney

    Mr. Swain, Thank you so much for the service Capital Well provided at my home today. I left a message with you at the behest of Ed Monty. I received a prompt phone call from Greg to arrange for a service call and to discuss what might need to be done. Promptly at (actually a few minutes before) the scheduled time, Bobby showed up to perform the service. Bobby was excellent at explaining the service, why some things were needed and how the well and pump worked, and answered all of my questions to my satisfaction. All in all, this was a very positive experience for us. Thanks to you and the people at Capital Well for prompt, courteous, and efficient service.
