We have used Clean Sweep Chimney & Stove for quite a few years now. Their employees are always punctual, and show up when they say they will. And, they are friendly with us, and polite, and do a very good job of keeping our fireplace in a good, safe operating condition. Outside of just the routine cleaning and maintenance, we also used them once to install a stainless steel insert for us. They did a good job of that, too. So, we are very satisfied customers, and have no problem at all in giving Clean Sweep Chimney & Stove a five star rating all around!
