Masonry Waterproofing Tips

Chimneys are traditionally built from masonry. This is because well-constructed and maintained masonry can withstand the test of time. It is also ideal for chimneys because of it’s porous properties. These allow vapors, heat, and smoke to escape easily. However, the very materials that make it so ideal for a chimney, also make it susceptible to damage caused by weather. It’s vital to keep up with maintenance appointments and preventative care for your masonry chimney! Doing so will keep your chimney efficient, safe, and long-lasting.

Schedule Annual Inspections

The annual chimney inspection is the only time a certified professional may see your chimney system. This is the time when a chimney sweep will get up close and personal with your masonry, noting inconsistencies, cracks, flaking, and more. The inspection includes all accessible portions of the system. This include the fireplace, chimney, crown, and cap – vital parts of the chimney system that protect it from water damage.

Schedule Repairs as Soon as Possible

Do you notice a problem with your masonry? Discoloration, spalling, cracking, or any significant change in the masonry means you should contact a certified professional! After a diagnostic appointment, he should be able to make a recommendation which may include masonry repairs. If your chimney needs repairs, get them scheduled as soon as possible. Now is the time to make these repairs. The masonry may not be susceptible to water penetration through the upcoming winter months.

Waterproofing Services

After your masonry is built, repaired, or cleaned, you can add even more protection by applying a waterproofing sealant. We recommend it as a regular preventative method that can keep your chimney working properly for longer, despite harsh winters and wet springs. This specially designed sealant is vapor-permeable. The vapors and smoke still escape, but water molecules are unable to get in. A similar product can be applied to the chimney crown to repair cracks and deterioration there, as well.

Visually Inspect the Cap and Flashing

In between your chimney sweeps and annual inspection, you can visually inspect your own chimney components. For instance, your chimney cap should be secured to the top of your chimney flue. If it is crooked or missing, you need to call and have a new one installed. Chimney caps protects the interior of the chimney from water damage. The flashing protects the outside of the chimney, specifically the intersection of the roof and chimney. If you can no longer see flashing where you once did, or if you have a leak in another area in your home, the area around the base of your chimney is most likely leaking!

A masonry chimney is not built and then forgotten. It works every day through the burn season, so it needs periodic attention and preventative maintenance. The best thing you can do for your masonry chimney is to have it waterproofed. At Magic Sweep, we offer these services and more!
