4 Situations That Require Calling a Certified Chimney Sweep

Chimney sweeps clean chimneys. Sweeps with certifications from the Chimney Safety Institute of America (CSIA) have gone that extra mile to earn their place among the very best chimney technicians in the U.S. Chimney safety is nothing to take lightly, so if you ever encounter

Chimney Masonry Repair in Amherst, NHMasonry damage

Have you spotted crumbly dust on your roof around your chimney? Are some of the bricks loose? Is the chimney kind of tilting to one side? If you believe your chimney masonry is damaged, you need to have it looked at.

Bricks and mortar that make up a chimney can suffer damage for a variety of reasons including:

• Water leaks (see below)

• Earthquakes

• Chimney fires (see below)

• Normal house-settling

• Extreme hail storms

• Violent winds

• Plain old age



If your chimney’s masonry is compromised, it’s a good idea to cease using the fireplace until a chimney technician has performed a thorough inspection and made any needed repairs.

Leaky chimney

When a chimney begins to leak, a cycle of deterioration has begun that will not stop on its own. Water can get into a chimney system through damaged masonry, a cracked chimney crown, a missing or damaged chimney cap, missing or damaged flashing and more.

Over time, water and moisture will eat away at bricks and mortar and can lead to structural collapse. If water gets down into the flue, it can damage the chimney liner and internal bricks and leave the surrounding areas of the home at risk of fire.

Chimney leak signs include:

Water in the firebox

White stains on the exterior bricks

Damp sections of walls/ceilings near the fireplace

Strong odors coming from the fireplace

Chimney leaks should be inspected and repaired promptly by a professional chimney sweep.

Chimney Inspection in Concord, NHChimney fire

Chimney fires, usually caused by creosote in the flue, can be big, destructive events or small events that start and stop on their own. Even the briefest chimney fire can damage the flue liner and masonry. If you know or suspect you’ve had a chimney fire, the structure should be inspected before you use your fireplace again.

Common signals of a chimney fire include:

A rumbling/thrushing sound, similar to a distant train

Repetitive tapping sounds

Heavy, dense smoke leaving the chimney or entering the home

If you observe any of these signals, call 911 immediately and then put out the fire in the fireplace, if you can do so safely.

Smoke backing up into the house

If smoke is entering your home for reasons other than a chimney fire, it means there is some kind of drafting problem. Obviously you want to keep smoke out of the house, but the biggest concern is the carbon monoxide that is present in smoke. Carbon monoxide is odorless

A certified chimney sweep can help with drafting issues by determining why there’s a problem in the first place and then making the necessary repairs.

Drafting issues are often the result of:

  • A flue full of obstructing debris such as small-animal nests, leaves and twigs
  • Excess creosote in the flue
  • A chimney flue that’s the wrong size for the fireplace
  • A house that’s too air-tight to allow enough air into the firebox (may solve by cracking a window)

The situations listed above are all good reasons to call a professional chimney sweep. Beyond emergencies, an annual cleaning and thorough inspection are great ways to ensure that your chimney and fireplace remain safe and working at peak efficiency.

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.

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)
