Frequently Asked Questions


I got my chimney swept 6 months ago why do I need another one already?

Creosote accumulation depends on many different factors. Typically, is it the moisture of the wood. If you are burning un seasoned or damp, wood it will make the flue build up with sticky black creosote very quickly. Wood with 15-20% moisture content is going to be the best fuel for your chimney as it won’t create as much creosote. 

Why do I need to have my chimney swept?

Chimney fires are typically caused by build up of creosote, which could be very dangerous for you and your home. Creosote is also very acidic so it will deteriorate your flue if it is not properly and regularly cleaned. 

Will I receive a report for what the tech found during the sweep?

The tech has 24-48 hours to send you an estimate and work order. The work order you receive will have information such as how much creosote was in your chimney, and any issues they may have found.

If there is a problem with your appliance the tech will immediately notify you. The tech will also give you an estimate for any repairs needed to get your chimney in safe working order. Our customers safety is always our top priority. 

What do I need to do to prepare for my chimney sweep?

To prepare for your chimney sweep you should let the appliance completely cool for 24 hours before your scheduled appointment. Our techs are not able to clean a flue if it is still hot.

What is a chimney sweep?

A sweep is a term we use in this industry to describe a cleaning. The tech will clean the chimney from the bottom up with a powered drill that will ensure the flue is completely clean. The tech will use different attachments depending on your flue type and how much accumulation has built up.

Payment is due upon completion of the job. Payment can be made by cash, check or credit/debit card. Credit/debit card payments can be made over the phone or online with the link we provide with your invoice we email.

I wanted to give 5 stars but they are very busy which meant I had a good wait for both the inspection/cleaning, then for a quote on repairs and then for the repairs. Their prices seemed a little high to me but I have nothing to compare with as they were highly recommended by someone I trust and other companies had plenty of negatives reviews which kept me from getting additional quotes. I am happy with the work and they promptly returned to fix a mistake that had been made. Chris the inspector, Jennifer in the office, and Alex and his repair crew were all pleasant and took the time to answer all of my questions. Alex and his crew even took their shoes off (it was winter) before entering my house without even being asked! So if you are not in a rush and want to ensure you chimney is as safe as possible then I think you'll be happy with Black Moose.

After a recent sweep of our chimney, it was discovered that our flue tiles were cracked. Black Moose techs were hard working, detail oriented and professional! Nice jobs guys! See you next year for my cleaning!

Excellent I highly recommend Black Moose Chimney and Stove; Kelly and Liam are awesome, they did a great job. Extremely professional, arrived early, went through everything with a fine tooth comb ensuring pellet stove was thoroughly cleaned. They also were respectful of my home, conscientious and cleaned up after themselves. Made sure stove worked prior to leaving and told me to call promptly if anything came up afterward. Will definitely use them again.

We've had Black Moose clean our chimney for a number of years.But recently, we had an emergency situation at our home involving our chimney & oil furnace flue, which was caked full of soot from a malfunctioning furnace. They came & cleaned out both flues in no time, even going up on the roof with snow on it! They cleaned up after their work in the interior rooms where the oil furnace and the woodstove are located. Great work. Reasonable prices. Very nice people. You can't go wrong with Black Moose.

Goods: The technicians know their business, very efficient in cleaning/inspection along with cleaning up after the 'dirty work'.Others: Communications could be more effective. Despite early coordination about scope of work (multiple flues within same chimney) the estimate provided did not reflect this and the final invoice was significantly more than the estimate provided.Quote for follow-on chimney relining was significantly more than that offered by other companies in the area (and far more than neighbors experienced for similar work accomplished by other companies)
