When Should I Use a Chimney Chase Cover, and Why Do I Need One?
First and foremost, let us clarify what a pursuit cover is not: Instead of covering stone chimneys, chase covers are used to cover the boxes (chases) that house a factory-built chimney. [source: wikipedia] Basically, it’s the top of the box that goes up either the side of the house or through the centre of it, rising over the roof.
A chimney chase cover is a crucial and required investment in order to extend the life and maintain the structural integrity of your chimney and your property. Precipitation, debris, and animals are kept out of a chimney by using a metal chase cover, which is attached to the chimney. It is not an option; rather, it is a need.
The cost of replacing a chimney chase cover or cap
A new chimney cover will cost between $150 and $200, not including installation. The cover (also known as a cap) serves to protect your flue and is located at the very top of the chimney. \
For a single flue stainless steel chimney cap with expert installation, the typical cost to replace a chimney cap is between $300 and $600. For a stainless steel chimney cover for a double flue with professional installation, the average client pays approximately $350.
Considerations for Chase Cover Design/Specification
It is also critical to ensure that your chase cover is constructed according to exacting standards. You should allow around 14 to 12 inches all the way around, and the cover should be positioned approximately 1/8 to 14% of an inch away from the pursuit. This ensures that the cover is not too tight to install, but that it covers the whole top of your chimney from tiny animals while yet allowing for a modest amount of ventilation to pass through.
Is it possible to cap off a chimney?
To build a lead cap, which is an old and almost costless way of capping off or sealing a chimney that is no longer widely utilised, follow the instructions below. Simple lead scraps or offcuts may be pounded into the appropriate form and then glued to the top of most chimney pots to successfully seal and waterproof them.
What is the expected lifespan of a brick chimney?
What is the lifespan of chimney liners? It is dependent on the sort of chimney liner you have as to the answer to this query. Clay tile liners and cast-in-place liners have a life expectancy of around 50 years. Stainless steel flue liners have a lifespan of 15 to 20 years on average (though low quality liners may not even last for five).
