Keeping the April Showers Out!


Water infiltration is a big deal for masonry chimneys. Water can enter masonry and erode mortar joints, decay brickwork, and when it freezes it can split crowns and brickwork apart. Water can also enter through chimneys and flashing and rot and decay the wood structure of your home. Keeping water outside where it belongs can be a very difficult task, especially on older New England homes.

Having a proper chimney crown can be a major help. A properly built crown extends beyond the brickwork of the chimney to move rainwater away from the masonry. It overhangs much like the eaves of a roof do on your home. Still, most masonry chimneys have what’s known as a wash, which like a crown is a concrete top on a chimney, but unlike a crown it doesn’t overhang. Instead, water runs to the edge and then down the brickwork, possibly leading to infiltration into the chimney. Repairing a damaged wash will help to keep water out, but if at all possible pouring proper crown will make a big difference.

Flashings are also very prone to leaks, especially when improperly done. When budgets are tight but repair is needed, a flashing sealer can be an effective and inexpensive solution to keep water out. Flashing sealer is a paint on rubber layer which lays over top of the flashing like a big rain coat. It dries quickly and is pretty effective at keeping out rainwater.

Finally, make sure you have a cap installed. Caps do wonders to keep rainwater out of the flue interior which greatly helps extend the lifespan of your masonry flue. This is especially important on a flue serving an oil appliance.

Enjoy the great weather and watch out for the black flies!

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)
