Chimney Waterproofing

If you want your chimney to last you’re going to need some Chimney Waterproofing. Resistance to water penetration into the brick and mortar is key to your Chimney’s lifespan. Water can cause deterioration, corrosion, efflorescence, and spalling of the bricks, and if left unchecked will cause structural failure. Look no further than 1800 Chimney for chimney and fireplace waterproofing!


Severe erosion and deterioration happens when water penetration occurs. Bricks will begin to crumble as the water damage becomes more severe. This is not safe and should be addressed immediately! After repairs are done, a water-repellent treatment will protect the repair and the rest of the structure against further damage.



The white stains, on the bricks below, are called efflorescence. Efflorescence on chimneys indicates that water penetration and salts are present and migrating to the surface. In other words, it’s a sign that moisture problems are taking hold. Call 1800 Chimney inc immediately if you see this white staining. This means you certainly have a moisture problem. We will inspect and assess the damage, and only then can we make the proper recommendations about your chimney efflorescence situation.


Water also causes damage during the freeze/thaw cycles we experience in our area, leading to structural failure and spalling. This is when the face of the brick begins to separate and as a result, may even fall off. If you notice pieces of brick lying at the bottom of your chimney, it’s time to call in the experts to prevent further damage.



1800 Chimney technicians will inspect your chimney in detail. Our Techs can spot hairline cracks and openings in mortar. These will most likely need to be repaired as well as treated. If the liner is letting moisture into your masonry, a new stainless steel liner may be recommended. The most common solution offered to reduce the amount of water entering your chimney is a chimney waterproofing.

If you are looking for a good price and professional service then look no further. Paulie, the service technician is a rock star when it comes to chimneys, he sucessfully restored my 100 year old fireplace 2 years ago and did it for a super affordable price explaining everything to me along the way. I can now enjoy my fireplace like I always wanted. Highly recommended.
