Older homes with original wood or brick siding will need to be replaced more frequently. Signs of wear include fading or cracking, discoloration or warping, and any sort of mold or rot. Older homes can also have costly utility bills. Re-siding your home can ensure it is properly sealed and energy efficient. Typically, vinyl siding lasts between 20 to 40 years. Adverse weather conditions and sun can affect your siding’s lifespan, but in general, vinyl siding is manufactured to last.
