From the street, your home is not the only thing that is noticed. People can notice your car, yard, and even your chimney. It may seem ridiculous but it has an impact on the home. Your chimney is subjected to continuously changing climates throughout the year. The blazing hot sun, rising stickiness, driving precipitation, a profound freeze from the outside components negatively affect the brickwork. Keep in mind that bricks are normally strong structure material, but they do take on a lot of wear and tear. The best way to prevent damage from dampness and water is to block with a sealant around the chimney cap.

The chimney cap is located at the top of the chimney. It is best to seal this area along with the area where the chimney connects to the home. Do you wonder what is the best sealant for your chimney cap? Sealants are designed to impede liquids from entering the material it is on. There are two different types used – silicone or polyurethane. Not all sealants are made equivalent. Below are some differences to think about when using a sealant on a chimney cap.
