Both the guys were excellent in the fireplace and the dryer vent cleanings. They were on time as promised and worked quickly with a high degree of cleanliness. When time to pay with our credit card the price for each was correct as quoted. To me, the unbelievable part was when they gave me the hand held to sign, a “tip” starting at 15% was expected! I guess they think they are a restaurant. I gave a 15% tip only because I was taken back and didn’t want to appear cheap. If they aren’t paying their well deserved employees enough then they need to raise their prices, not cheap shot asking for a tip. Because of this, and only this, I will not use them again.
