Slab vs Crawlspace

Written by Allisha Eytcheson Smith

Feature	🕳️ Crawl Space	🧱 Slab Foundation
Construction Cost	More expensive than slab	Less expensive upfront
Access to Utilities	Easy access for repairs & upgrades	Harder to access; requires cutting the slab
Moisture Control	Better in flood-prone areas (elevated)	Prone to water intrusion in floods
Pest Risks	Higher—can harbor pests if not sealed	Lower—less space for pests to inhabit
Energy Efficiency	Can be less efficient if uninsulated	Generally more energy-efficient
Maintenance Needs	Requires regular inspection & maintenance	Minimal ongoing maintenance
Comfort (Floor Feel)	Can feel softer or springier underfoot	Hard surface; colder underfoot
Durability	Susceptible to moisture if not sealed	Very durable and stable
Storage Space	Can offer limited storage	No extra space
Climate Suitability	Better for wet/hilly areas	Better for warm, dry climates
Resale Value	May be preferred in certain regions	Popular in many areas for low maintenance
Construction Time	Takes longer to build	Faster and simpler construction

After the past two posts, you should be well educated on the pros and cons revolving slab foundations and crawl spaces. Now I present the actual side-by-side table to break down and simplify the two. Here in North Carolina, you're going to see both of these styles interchangeably throughout the region, but also sometimes within the same neighborhood based on the terrain. One is neither better nor worse than the other, just different. Happy house hunting, and for now I must:
