Protect Your Chimney With Waterproofing – We Can Help

No matter where you live, your chimney is going to be exposed to the elements. And thanks to all that Mother Nature throws our way – snow, rain, wind, and the endless cycle of freezing and thawing – you can bet your chimney is feeling the relentless impact of weathering and deterioration.

Due to their porous nature, masonry chimneys absorb large amounts of water. Bricks are like sponges, soaking up water and wicking moisture into the chimney structure. Unfortunately, chimney water damage is a slow, subtle process, and in many cases, you will not notice it is a problem until serious structural damage to your chimney has already started.

Can I Waterproof My Chimney Myself?

If you walk into any hardware store, you’ll likely find some kind of chimney water-repellent solution, which leads you to believe that people are doing these services themselves every day. However, there are some important considerations to keep in mind:

  • Safety: Working on a chimney obviously involves working at heights. Do you have the necessary safety equipment and safety precautions in place to avoid any accidents or injuries?
  • Skill & Experience: Waterproofing a chimney requires a good understanding of masonry and the proper application of sealants. We have over 17 years of experience and are confident in our ability to select the right materials, apply them effectively, and ensure your chimney remains shielded from the elements for years to come.
  • Choice of Sealant: In order to properly waterproof the masonry of your chimney, a breathable waterproofing agent must be used. This is very important because if you don’t use a breathable repellent, any water or mildew that is already in the masonry will be trapped inside. This can lead to further erosion and damage to the mortar and overall chimney structure. Here at Mr. Smokestack Chimney Service, we have a complete line of products specifically designed to protect all areas of your chimney from water intrusion – without locking it in.
  • Preparation & Repairs: Properly preparing the chimney surface includes cleaning and repairing any existing damage in order for the sealant to adhere correctly. Most homeowners don’t know how to thoroughly assess a chimney – let alone repair one. Mr. Smokestack Chimney Service will come to your property, evaluate the condition of your chimney, determine if there is existing damage to your chimney, then properly apply the waterproofing sealant.
  • Weather Conditions: Ideally, chimney waterproofing should be done in dry, mild weather conditions to allow the sealant to cure properly. If we had to pick the best time of year to perform this service, it would be in early spring. That way, we have enough time to make any necessary repairs and properly waterproof your chimney well before you need to use your fireplace.

At Mr. Smokestack Chimney Service, all of our technicians are highly trained in the inspection, repair, and waterproofing of chimneys. Rest assured that, when you trust us, you will be completely satisfied with your chimney’s maintenance and longevity, knowing it’s in the capable hands of our skilled professionals.

What Are Common Services That Help Further Waterproof a Chimney?

In North Carolina, we are no strangers to extreme weather conditions, including high winds and heavy rain. Here, it’s even more critical to protect your chimney and your home from the expensive damage that will result from water breaches.

Fortunately, at Mr. Smokestack Chimney Service, we have many services that we would recommend in order to further protect your chimney and fireplace from moisture penetration. This includes:

  • Chimney Cap Installation: The simplest way to keep moisture from penetrating your chimney is by ensuring a chimney cap is properly installed. When moisture is able to gain access to the inside of your chimney, the components within your chimney will begin to rust, wear down, and deteriorate.
  • Masonry Repair: When the water trapped in the brick freezes and thaws, it causes the brick to crack. Tuckpointing and spalling brick repair are just a couple of ways we can help take an old worn out chimney, and make it look as good as new again. Anytime we see mortar or brick beginning to flake, crumble, or decay, we worry about the structural integrity of the chimney and the potential safety hazards it could pose. We recommend these types of repairs be done as soon as possible.
  • Flashing Installation: The chimney flashing is the metal portion located between the roof and chimney. This acts as a watertight seal, ensuring all rain that runs off your roof is directed away from the base of the chimney. It is common for flashing to rust over time and cause leaks within your home – which is why it’s important to have your flashing installed and checked regularly by a professional chimney technician.
  • Crown Repair: A chimney crown is the flat surface at the top of the chimney that is made of concrete. Just like the rest of the chimney structure, the chimney crown is vulnerable to everything Mother Nature throws its way. Over time, this leads to cracks that can allow more water to seep in, reducing its lifespan. It is important to fill the cracks – or replace the crown altogether – before applying a chimney crown-specific coating.
  • Waterproofing: Because water penetration is the number one cause of deterioration and damage in chimneys, waterproofing is a good way to help prevent experiencing any problems in the future. Sealing your chimney with a vapor-permeable solution is one of the simplest and most affordable ways to prevent water from penetrating the bricks.
