Waterproof Your Chimney to Prevent Damage

Your chimney is exposed to all weather conditions. The effects of the weather, especially moisture, can seriously harm your chimney. Water is actually a chimney’s deadliest enemy, according to the Chimney Safety Institute of America, which urges property owners to take every precaution to keep their chimneys dry. We at Local Chimney Sweep Cleaning advise our clients to think about waterproofing to assist prevent water damage to their chimneys and residences.

Water poses the greatest risk due to the freeze-thaw cycle. The porous masonry of your chimney absorbs part of the water that splashes on its sides from rain, snow, or ice. There is a lot of porosity in the bricks that make up your chimney. As a result, they frequently allow condensation and water to pass through them. Due to temperature changes, this technique could be damaging to the bricks; as the water expands inside the bricks, it causes the bricks to spell, which is a phrase for how they break off in pieces. If a chimney needs to be repaired because of spalling, it may cost a lot of time and money. The water inside the chimney’s walls freezes and expands as a result of falling temperatures, which leads to cracking and collapsing. The continual freezing and thawing of the water within the masonry of your chimney over time can weaken the construction of your chimney and affect its capacity to hold fires, heat, and smoke.

In addition, moisture can harm your fireplace and chimney in additional ways. Water that gets into your chimney might combine with creosote and fill your house with an unpleasant odor. The water may also result in rusty fireplace doors and dampers, fractured flue tiles, and rusted dampers. Your home may sustain damage from water seeping into the structure, including discolored ceilings, sagging wallboard, and decaying joists.

Using a waterproofing coating on your chimney is one of the best methods to safeguard it. A waterproofing treatment keeps the masonry of your chimney from absorbing almost all of the water. At the same time, it permits the brickwork of your chimney to “breathe” so that any moisture won’t become caught in the walls of the chimney and the smoke and gases from your fireplace can still usually depart your chimney. The majority of chimney waterproofing methods come with a five- to ten-year guarantee to keep your chimney safe.

You should also take other precautions to prevent water from harming your fireplace and chimney. Ask your chimney sweep about the condition of three crucial chimney components as part of your annual chimney sweeping and inspection. Water cannot enter your chimney’s flue if your chimney cover is tight. The exterior walls of your chimney are protected from precipitation by a properly constructed, damage-free chimney cap that also directs water away from the opening of your chimney. Additionally, you should make sure that the metal flashing that surrounds the base of your chimney is not corroded or damaged.
