Professional Chimney Cleaning

Our Granite State chimney sweep services focus on two primary areas of the chimney cleaning process:

1. Remove creosote. Creosote forms whenever fires burn in your fireplace. Sticky and highly flammable, creosote is responsible for most chimney fires in the U.S. each year. We use special brushes, scrapers and vacuums to protect your chimney from this dangerous substance.

2. Remove obstructions. Chimneys tend to collect various debris, which can create an air-flow obstruction in your flue. Things like leaves and twigs from nearby trees, small-animal nests and even the small animals themselves can block the draft and send smoke and toxins back into the home.

As a recognized leading chimney sweep in south-central New Hampshire, Black Moose holds membership with the National Chimney Sweep Guild and the Northeast Association of Chimney & Hearth Professionals. Our technicians are certified by the Chimney Safety Institute of America, the most respected certifying body for chimney professionals in the United States.

Chimney Inspection

Chimney cleaning and chimney inspections go hand in hand. When a chimney or its components become damaged, the average homeowner often won’t be able to spot the exact problem. A thorough chimney inspection by trained technicians will examine your chimney and fireplace system inside and out, from top to bottom, and uncover early signs of wear and damage so they can be addressed quickly.

Chimney Repairs

The majority of chimney repairs center around three objectives: keep water out of the system, maintain the chimney’s structural integrity and prevent chimney/house fires.

Damaged bricks and cracked mortar compromise the integrity of the chimney and give water a clear path inside the structure, where it can cause significant decomposition. A cracked chimney crown, a damaged chimney cap and warped flashing also provide access to rainwater and melting snow. A cracked or split clay chimney liner exposes masonry and combustible building materials in the home to intense heat that could lead to a fire.

Our comprehensive chimney repair services include:

  • Chimney liner repair/replacement
  • Chimney masonry repair (see below)
  • Chimney crown repair/rebuilding
  • Chimney cap repair/installation
  • Chimney chase top repair/replacement
  • Chimney flashing repair/installation



chimney masonry repair & chimney rebuilding in Manchester NH

Masonry Repair

A chimney’s masonry must be in good shape to allow it to withstand high levels of heat, freezing weather, heavy winds and the periodic settling of the house. If a chimney inspection has discovered compromises in your chimney’s masonry, our skilled brick masons can get right to work to solve the problem.

Our chimney masonry repair services include:

Tuckpointing: We’ll replace missing sections of brick and mortar to restore strength to your chimney.

Smoke chamber parging: This process smooths out the interior of the smoke chamber to allow for smooth, efficient drafting of smoke and toxins.

Chimney crown rebuilding: Cracks in your chimney crown allow moisture to infiltrate the bricks below it. We rebuild severely damaged crowns. When cracks are minor, we can seal them with a waterproof coating.

Chimney rebuilding: In cases where a chimney’s structure is significantly damaged, we can perform a partial or complete chimney rebuild to restore safety and prevent a major disaster.

Black Moose Chimney & Stove of Antrim, NH, is ready to help with all your chimney sweep, chimney inspection and chimney repair needs. We serve customers in the south-central New Hampshire counties of Hillsborough, Cheshire, Merrimack, Sullivan and Western Belknap. Call us today at (603) 525-7905.

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)
