When to Repair vs Replace a Crawl Space Foundation Not sure whether to repair or replace your crawl space foundation? Here's what you need to know: - Repair Costs: Typically $4,500–$8,000. Ideal for minor issues like hairline cracks, localized sinking, or moisture problems. - Replacement Costs: Ranges from $20,000–$40,000. Necessary for severe structural damage, extensive wood rot, or foundation failure. - Key Signs of Damage: Look for sagging floors, sticking doors, diagonal cracks, standing water, musty odors, or pest activity. - Decision Rule: If repair costs are 40–60% of replacement costs and won’t significantly extend the lifespan, replacement might be the better option. Quick Tip: Repairs are less disruptive and eco-conscious, while replacements reset the foundation’s lifespan and improve long-term stability. Always consult a structural engineer for an expert assessment. ::: @figure !Foundation Repair vs Replacement: Cost and Decision Guide(https://assets.seobotai.com/undefined/...
