Dangers of Spalling

Chimney Leak repair in Keene NHA typical problem we notice at the close of winter? The appearance of cracking, crumbling, and falling masonry. This occurrence is a common occurrence when moisture has penetrated the masonry. When water is allowed to penetrate the masonry it experiences a freeze/thaw cycle that is especially damaging. The water freezes, expanding and damaging the brick and mortar. Afterwards, it then thaws, moving further into the masonry, and repeats the process. Spalling causes a host of problems for your chimney. It can and should be repaired as soon as possible.

The Danger

  • Structural Problems.
    Masonry joints can become riddled with holes and cracks, compromising the structural soundness of the chimney.
  • Falling Bricks and Mortar.
    As the mortar recedes, cracks, and falls out of the masonry, it can lead to bricks falling. This can damage the roof and flashing. It can also fall from a steep roof, possibly injuring bystanders.
  • Water Damage.
    Spalling masonry can create cracks and holes. These allow even more water into the chimney. Consequently, not only damaging the masonry itself, but causing rust, stains, deterioration, and water leaks throughout the entire system. A chimney leak lowers the chimney’s efficiency, costing you more money, fuel, and raising fire risk.

What is Tuckpointing?

At Black Moose Chimney we see spalling often. It’s one of the more common occurrences that we can repair through tuckpointing, or repointing. Tuckpointing is a tedious job in which a chimney sweep removes the damaged masonry brick by brick, replacing it with new mortar. This should only be completed by an experienced chimney sweep because if done improperly it can add to the problem. The new mortar must be matched to the old mortar in consistency, strength, and color or it ends up weaker than before. When done correctly, the chimney looks as good as new and there is no hint of past damage or a repair.

Fixing the Whole Problem

At Black Moose we don’t only fix the problem, but we repair the damage. It’s important to repair water damage before it worsens. When water mingles with soot it becomes highly corrosive to the surfaces of the chimney. For instance, your chimney sweep can assess the liner, firebox, and various chimney parts to insure it is at its best. Black Moose relines chimneys with HeatShield® technology to give you a liner that is good as new, without having to replace it completely. We also offer an extensive menu of masonry repair services to restore your entire system to full function, with the highest level of safety and 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.

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)
