Maine Line Water & Radon Treatment

Residential & Commercial Services

At Maine Line Water and Radon Treatment we have over 15 years' experience in designing residential and commercial water treatment systems and radon water and air systems. Our company is certified by the state of Maine for the mitigation of radon in water and air, along with the testing of radon. We also have the ability to treat lake water, "so it's drinkable". Maine Line Water and Radon Treatment will do a free limited water test on site. At the request of the homeowner we can offer a "certified lab" test of the water, which we "highly recommended". After the analysis has been done we will make recommendations for a treatment system.

We also offer Daikin heat pumps as your year round comfort solution. Daikin heat pumps can deliver heat in conditions as low as -13 degrees Fahrenheit to keep you warm and toasty inside and keep you cool during the hot summer months. They also offer air filtration benefits by removing airborne particles, resulting in cleaner filtered air being redistributed throughout your home. Sales, service and installation all done by our experienced heating and cooling specialists.
