Crown Repair and Rebuild

Every part of the chimney system has an important job that helps the chimney vent the fireplace properly and last as long as it should. The biggest culprit shortening the lives of chimneys across the country is water. Rainwater, snow, ice, and even humidity in the air can damage the chimney system. According to the Chimney Safety Institute of America (CSIA), a chimney leak can destroy the chimney from the inside out, causing rust, deterioration, rot, stains, clogs, cracks, and even collapse and settlement. Your chimney is built to last, but only when components are maintained and repaired when necessary. We repair and rebuild chimney crowns to keep chimneys working in New Hampshire and we can fix yours too.

The Importance of the Chimney Crown

Like homes and shelters, the chimney needs a roof to protect it from water damage that can be costly and dangerous. The crown acts as a roof, directing water off and away from the chimney opening, protecting from the top-down, and working with the other parts of the chimney (caps and flashing) to protect the system year round. The chimney crown should be made in a specific way, with appropriate materials for the most effectiveness. While many amateurs may use extra mortar to fashion the crown, it should be constructed of concrete and reinforced with metal or steel mesh. Mortar will crack and deteriorate quickly when exposed to sunlight and weather, but concrete stands the test of time. At Black Moose Chimney and Stove we use the best material when we construct crowns and we pay attention to other details that make up a quality product.

Thickness – The concrete chimney crown should be 2 inches thick at its thinnest point to prevent unnecessary deterioration.

Shape/Slope – From the center to the outer edge of the crown, there should be a slope that allows water to run off the chimney top. Without the appropriate slope, water will pool onto the crown and cause gaps and cracks. During winter this water will freeze and expand, leading to more severe winter damage.

Overhang – In addition to the slope, the crown should extend from the flue to the edge of the chimney with a two inch overhand. This overhand and drip edge allows the water to drip down and onto the flashing and roof, keeping water from affecting the masonry itself.

Repairs and Rebuilds

When your chimney is cleaned or inspected, your chimney professional may recommend a repair or rebuild. When the crown damage is minor, the crown can be sealed with an industrial product that fills cracks and gaps with ease, restoring the crown to full and safe function. With major damage, you may need a full crown rebuild. If this is the case, Black Moose Chimney and Stove can construct a new crown that custom fits your chimney and lasts as long as the chimney when properly maintained.

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)
