The Magic Of CrackMagik

Cracks in your chimney’s mortar joints will leave your chimney system exposed and vulnerable to water damage. Even small cracks can quickly become big problems, as water gets into the masonry and, freezing and thawing, attacks it from the inside out.

It may be that the best way to repair cracked masonry is to have a chimney professional perform detailed tuckpointing work, removing cracked joints and replacing them with new ones, and removing and replacing damaged brick. Significant damage can indeed create a situation where tuckpointing and replacing — even rebuilding — might be the only safe option. However, if we catch cracks and other damage before it gets to that point, there’s another option: ChimneySaver’s Elastomeric Crack & Joint Sealant, CrackMagik.

This product can repair and seal minor cracks and small holes up to 1/8 of an inch in size, stopping the leaks that result from the cracks and holes, and saving you the time and considerable expense of having tuckpointing work done. And once repairs are completed by CSIA-certified Blue Sky Chimney Sweeps’ technicians, you can expect long-lasting results — this Crack & Joint Sealant carries a 10-year warranty.

If your chimney is leaking, or you notice cracks in your masonry, call Blue Sky Chimney Sweeps — we’ll inspect your damage and tell you whether or not CrackMagik is right for your chimney.
