This photo previewed is an example of our new stainless steel cap (left side) compared side-by-side with an old cap (right side). Our stainless steel caps will out last, the commonly used, galvanized metal caps. Plus our caps allow larger room between the flue and the top of the cap to make sure your smoke is free to escape away from the chimney. This customer was in urgent need to get this fixed because the smoke would rise through the chimney but be pulled down through the water heater flue. We have gained another happy customer and hope that we can gain more with every repair we provide!
