My furnace vent/chimney was blocked by what turned out to be a birds nest. Not an easy access for the bottom end but they did it anyway. Cleared the nest and made sure it wouldn’t happen again.

Randy and his crew helped diagnose and fix a unique chimney issue quickly and at a very reasonable price. They even went out of their way to help me find a company to help me with some other repairs that they couldnt do. Recommended highly!

Randy and his crew replaced an old woodstove that was in my house when I bought it. It wasnt up to code and I wanted a stove that would heat my entire house, be energy efficient and have very low emissions. He suggested a few different styles, I picked one and he took it from there. I thought it would be a long process but he got it ordered, ripped out the old one and installed the new one in a very short period of time. The end price was less than he quoted. Its been a year now and its running strong. Hes a good honest man to hire.

I made an appointment with them. They changed the time which we accommodated a few days before. Then they never showed up and when I called the number the office said they would call back with an update on their arrival and never heard back. I was very disappointed and do not plan to reschedule.

Extremely unprofessional. I opened our door and both of the men commented on the age of the home (my husband said when booking the appointment that it was a historic home). They went on to harass me about Do you know the age of your home? I wont be able to guarantee that this is safe... etc. I promptly called my husband to come home immediately. Furthermore, they did an awful job! My husband had to redo their work. We paid $160 for nothing. I would not recommend them!

Randy and his crew at A Clean Sweep were fantastic.We purchased a slightly used fireplace insert off Craigslist and had them install it.They worked with us every step of the way, from making sure that the fireplace was up to Longmont code before we bought it, inspecting the fireplace to make sure it would work, installing it, and even troubleshooting it afterward.A Clean Sweep went above and beyond what we paid them for. And after two beautiful fires recently in snowy Colorado, we couldnt be more grateful.

Great friendly service. These guys know what theyre doing. You get the feeling they are there to help you, not extract as much money as possible from your wallet.

Great service. They showed up on time. They found the chimney was already clean, and charged a modest amount for an inspection. I recommend them highly.

Andrew and Jarrod did me proud. Flexible, knowledgeable, professional.
