read this if your chimney is in bad shape

Regular chimney maintenance and inspection is crucial for the safe and efficient operation of your fireplace or wood-burning stove. Here are some signs that your chimney may need repair:
​

1. Damaged or missing chimney cap: The chimney cap helps prevent water, debris, and animals from entering the chimney. If the cap is missing or damaged, it can lead to problems such as water damage, animal infestations, and blockages.
2. Cracks in the chimney masonry: Over time, the masonry of your chimney can deteriorate due to exposure to the elements. Cracks in the masonry can allow water to seep into the chimney, which can cause further damage and reduce the efficiency of your fireplace.
3. Damaged or missing flashing: The flashing is the metal strip that seals the joint between the chimney and the roof. If the flashing is damaged or missing, water can enter the chimney and cause damage to the surrounding roof.
4. Excessive creosote buildup: Creosote is a byproduct of burning wood that can build up in the chimney over time. Excessive creosote buildup can increase the risk of chimney fires, which can be dangerous and cause extensive damage.
5. Smoke in the house: If you notice smoke or a strong odor coming from your fireplace, it could indicate a problem with your chimney, such as a blockage or a damaged flue.

If you notice any of these signs, it is important to have your chimney inspected by a professional chimney sweep like Mr. Happy Chimney which serves the Cambridge area.
