Why is My Siding Chalky? Central Michigan Solutions
If you’ve ever brushed against your house and ended up with a white, powdery residue on your clothes, you are dealing with siding chalky Central Michigan homeowners often see on older vinyl or aluminum. This “chalk” is actually a sign of oxidation. Over years of exposure to the sun’s intense UV rays, the resins in your siding begin to break down, leaving behind a fine powder that dulls the color and makes your home look aged.
While it is a natural part of the aging process, letting the chalk build up can make your siding more difficult to clean and eventually lead to brittleness.
