"This was a Saturday and we were really stuck! I texted Randy and he and Alan actually came to our house after their first job. We are not even in their service area. He ran some quick tests, checked out the well, called the installer and then recommended that we contact our water treatment services folks on Monday morning to run some tests to determine how to adjust our filtration system. Meanwhile, they assured us that we could use the toilets and shower (no hair washing). They GREATLY relieved our stress about this! All this because they sensed our stress and could help! All the info they provided - excellent! Randy and Alan could not have been more helpful. I would recommend them to anyone! Jennifer and John Wade in Lewiston"

I no longer have to worry. For myself, family and friends, I know I’ve made the right choice with the right company."
