Understanding Your Foundation

Types of Foundations

• Concrete Slab Foundation: Often found in newer homes; a single layer of concrete that’s a few inches thick.
• Crawlspace Foundation: Raised a bit above the ground, leaving space under the house for things like plumbing.
• Basement Foundation: A full or partial floor below ground level; can be used as extra living space but needs more care.

Why a Strong Foundation Matters

• Keeps Your Home Safe: A solid foundation keeps your house stable.
• Stops Water Problems: Good foundations help keep water out, preventing mold and rot.
• Saves Money Over Time: Fixing small issues early can stop big, expensive repairs later.
