Had Mark come by my house to inspect my existing soft water and reverse osmosis systems. It turns out the systems were old and not working correctly. He also pointed out how the original install was not done correctly and displayed a vast knowledge of everything mechanical concerning a house and property. I wanted a quality product and Mark had what I was looking for. The install became difficult due to the improper original install, but Mark persevered and didn’t charge me for the extra hours required to get the job done right. Mark even installed a couple of ancillary upgrades to the homes water system at no charge. Mark is your guy! Knowledgeable, Professional, Hard working and a great guy. Plus…he gave me a great deal!
