Matt and Northstar Services are terrific. Matt was punctual, called to confirm his arrival time, and really did a superior job under difficult conditions. My laundry room is small with a front loading washer and dryer set in minimal space but he cleared over 30 years of built up dryer lint from my drier to my roof exhaust. He actually left the system better than what he found it and gave us some great tips for future upkeep. I would not hesitate to have Northstar back and will recommend Matt and his company to all my friends.
