Caulking and sealing are important to maintain the integrity of the building envelope. This is because caulking and sealing are important in preventing heat loss, water damage, and sound transmission. Caulking and sealing is also necessary for the protection of building materials from environmental factors such as ultraviolet rays, oxygen, air, moisture, and mold growth. It is important to note that caulking and sealing should be done every year or when needed to avoid problems such as water infiltration or air leakage.
