Inside your chimney is a passage for flue gases, created by combustion, to exit your home. This passage is called a liner. However, some chimneys do not have a liner and flue gases travel inside the bricks that make up the chimney. If there is no liner in your chimney or if any of the flue tiles become cracked or broken, we recommend installing a stainless steel chimney liner. Our liners are appropriate for furnace flues, and fireplace flues.
Water damage and age can cause the mortar that holds your chimney together, to crack or crumble. Without supporting mortar, the bricks begin to loosen and sag. Unless the mortar is replaced, you could experience more costly repairs down the road. If your chimney has unfortunately deteriorated to the point that filling in the mortar (tuck pointing) will not be sufficient, then the next step is to rebuild the chimney. A Sweep Across the Bay would be glad to give you a written quote once we have assessed the damage whether you may need a full rebuild or just a portion of your chimney rebuilt.
The main purpose of a damper is to seal the fireplace when not in use making sure the heat stays in your home instead of escaping through your chimney. Having a broken damper or no damper at all, is like money out the window. Chimney caps come in all shapes and sizes. More chimney damage occurs from lack of a chimney cap that any other source. A chimney cap will not only stop the rain from getting in, but also any birds or other unwanted animals. Rain can cause premature deterioration of the interior of your chimney. This can allow for eroded flue tiles, lose crumbling mortar (which allow for dangerous cracks and blockages) or at a minimum, a rusted out damper.
