Chimney problems can cause illness and even loss of lives.

It's happened thousands of times - illness, even death, from carbon monoxide or sulfur dioxide poisoning.

With deterioration of the flue, the deadly gases can find their way into your home through even the smallest cracks.

In severe cases, the chimney erosion will lead to partial or complete internal collapse, blocking the flue and sending these poisonous gases into the home.

But fortunately, the problems of a deteriorating gas or oil furnace flue can be corrected without completely rebuilding your chimney.
