Certified Chimney Sweep

Annual chimney sweep services are recommended by virtually every fire-safety organization in the U.S. Why? Because when wood burns, a flammable substance called creosote forms and adheres to the liner or chimney walls. The more creosote, the more chance for a potentially dangerous chimney fire. Chimney cleaning also takes care of obstructions like falling debris from trees and small-animal nests that can hamper drafting and send smoke and toxins back into the home. Our chimney sweeps are certified through the Chimney Safety Institute of America.

Merrimack, NH, Chimney Inspections

A thorough chimney inspection is the best way to spot early signs of damage or deterioration within the chimney system and get it fixed before it becomes a costly problem. We perform all levels of inspection:

Level 1: Basic inspection covering visible components and the chimney structure

Level 2: Performed during real estate transactions, when attaching a new appliance to the chimney, or following a chimney fire

Level 3: In cases where significant damage has been uncovered during a previous inspection

Leaky Chimneys

Chimneys can leak for a variety of reasons. Have you noticed these leaky chimney signs?

  • Unpleasant odors in the room
  • Dampness on walls close to the chimney
  • Discolored chimney masonry
  • Water on the floor of the firebox

Damage to chimney components or to the chimney itself can allow water into the system, where it will begin a cycle of decay and rotting. If a chimney is obviously leaking, it’s likely in an unsafe operational state. Count on our CSIA-certified technicians to find the source of any leak and get it fixed quickly.

Chimney Masonry Repair

Damaged masonry should be addressed and fixed as soon as the problem is identified. The point of our chimney masonry repair service is to restore strength to the structure and to prevent water from infiltrating the system and causing major damage. If sections of bricks are falling away, we often can perform a process known as tuckpointing to fill empty sections of masonry with a strong compound that will add strength and life to your chimney. For minor cracking, we can apply a waterproof sealant to block water. Our CSIA-certified masons perform all levels of chimney masonry repair including historic chimney restorations.

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)
