Can Leaking Problems Be Something Other Than Weather Related? The Answer Is Yes!

Leaky chimney got you down? We hear you. A very common complaint we’re receiving this winter is those regarding leaky chimneys. But how can that be? Everything’s frozen! Or is it…??

Often, we assume that our pesky leaking issue is due to poor masonry, heavy rains, and/or roof problems. This is not always the case!  Weather-related leaks pick up in the warmer months when rain is a factor, but those aren’t the only leaks we’re seeing nowadays. There is another factor that can play a role in a leak that is most times overlooked – flue gas condensation.

Condensation happens when the combustion gases meet cooler temperatures in higher parts of the flue. Very cold weather or a chimney that is mostly exposed to the outside has an influence. Flue liners that are under/oversized or not the ideal material can cause excess moisture to accumulate, and instead of evaporating, can leak into the brick interior and cause damage on the other side.  Inadequate draft caused by either a whole or partial blockage has also been the culprit to an otherwise undisturbed system.  Excess condensation can collect at the blockage level and wreak havoc on drywall.

The condition of the flue liner plays a big role in the cause of moisture with condensation. The combustion products of gas are corrosive. While brick and mortar are most susceptible because they’re porous absorbing excess water like a sponge, eventually damaging terra cotta flue tiles, thus leaking into the adjacent walls/ceilings.

The solution – installing a stainless-steel lining system. Stainless steel liners do not absorb moisture like brick and mortar and do not corrode over time like terra cotta clay tiles. Some engineered lining systems also have water migration systems built-in to mitigate accumulation.   Our stainless-steel liners have a lifetime manufacturer’s warranty against rust and corrosion. The cost of the stainless-steel liner is minimal compared to the cost of having to repair the damage of the water penetration.

If your chimney is showing a leak in the cold winter months, you likely have an internal condensation problem.  Don’t wait until it’s too late – Give us a call to book your inspection to determine remediation today!
