I just moved into a new home that is 26 years old. The house has a chimney/firepace. In the fireplace is a Vermont Casting Gas Stove. Since we have moved in, when we have a significant amount of rain, water is accumulating on top of the gas stove. I called a chimney/stove company who came out and declared that the stove was fine and I needed a chimney cap, which I got. It is now raining hard again and the chimney is still leaking. I called the company who provided the chimney cap asking perhaps I need another kind of cap since water was still getting in. I thought that maybe with the wind, the rain was come in the grates on the side. The owner does not think that this is the problem, he thinks I need to repoint/waterproof the chimney - but of course this can not be done until there is better weather...I am wondering what is the right answer?
