Issues caused by the gap:
Water damage: Holes in the foundation or basement of the home may allow water to seep in, causing water damage, mold growth, and other related problems. This can be a particular problem when it rains a lot or when the snow melts.
Pest intrusion: The opening could provide a pathway for pests like insects, rodents, and other animals to enter the home. Infestations, property damage, and health problems could result from this.
Tripping hazard: For the elderly or people with mobility challenges, a space between the driveway and the home might be dangerous. Injuries and accidents may come from this.
Reduced curb appeal: Spaces between the driveway and the house can detract from the home's overall aesthetics and curb appeal by making it look messy and incomplete.
