Pros of a Slab Foundation

  • Better for moist climates as it prevents mold growth in the home
  • Less subjectable to insects and pests 
  • More affordable
  • Faster to construct
  • Sturdy and strong since slabs are 24 inches thick
  • Requires less maintenance
  • More energy efficient since it insulates the flooring of your house by preventing cold air from flowing underneath, unlike crawl space foundations
  • Durable—it can last for 50 years or more
  • Comfortable to walk on

Cons of a Slab Foundation

  • Cracks easily with shifting soil
  • Floods more easily
  • Tree roots can damage it. Homeowners are advised not to plant trees too close to the foundation—no less than 50 feet away
  • Repairs can be more expensive
  • No basement storage
  • Plumbing fixtures and electrical wiring are embedded in the concrete, and they’re not flexible if you want to do any future renovations
