Water Testing

Many minerals and chemicals such as radon, arsenic, chlorine, and lead are invisible to the naked eye. While the presence of excess iron, for example, is noticeable because it presents a foul odor and metallic taste, some other contaminants are completely odorless and tasteless.

Great company to work with, from the initial call to the service being done. Everyone was polite, knowledgeable, patient, and professional. Ryan was efficient and great to work with at our home. Thank you so much!

Excellent - so pleased with Capital!!! They installed a new well on my property last spring to replace an old dug well in a different part of my property. It was NOT an easy location to get to on my property!!! They worked SO efficiently and neatly.

Capital well was tremendously helpful and accommodating during the sale of my house. I would recommend using capital well, their service department is knowledgeable and wonderful with their customers!

Best water testing and well drilling on the east coast. I'd give 10 stars if possible. Extremely professional.

These guys are real professionals. Called on a Thursday mid-morning to see when they could come out to give me a price on getting my well pump replaced, they gave me the price over the phone and were willing to do the job on the same day.
