We Offer Chimney Waterproofing Services That Can Prolong The Life Of Your Masonry

When it comes to building a strong and durable, well-functioning chimney system, masonry makes for an ideal material. It’s been used in chimney construction for hundreds of years for a reason: masonry is strong and versatile and relatively easy to work with. It’s also permeable, which means that vapors and gases inside the system can escape through the masonry itself.

That permeability is necessary for proper function, but it also comes with drawbacks. As heat, cold, rain, and snow hit the chimney week after week, month after month, year after year, it takes a toll on the masonry. Even perfect, brand new bricks will absorb a certain amount of moisture. As the bricks and mortar start to wear down, they can begin to absorb far more moisture than they should, and that can lead to leaks and more serious damage.

Changing seasons will create particularly severe problems in degraded masonry chimneys. The brick and mortar will absorb excess water, which then constricts and expands inside the masonry. Constriction and expansion can cause deep and wide cracks, flaking, and chipping (spalling) and at its worst, it can even cause bricks to more or less burst from the inside out, creating the need for extensive, and more often than not, expensive repairs.

Blue Sky Chimney Sweeps can help keep that from happening by protecting your chimney masonry with a waterproofing sealant.

Make Your Masonry Last With A Waterproofing Sealant

Our technicians will apply a specially-formulated masonry waterproofing material that’s meant to protect chimneys, while still allowing them to function properly. The chimney waterproofing sealant we use is 100-percent vapor-permeable, so it’ll stop water from seeping into your brick and mortar joints, but vapors and gases that need to escape through the masonry will still be able to do so.

A waterproofing sealant can seriously reduce the need for repairs, and help your masonry last far longer than it would without this protection. It’s an affordable investment that will bring long-lasting benefits. Ask our technicians to tell you more about what waterproofing can do for your chimney system!
