Factors Affecting the Cost to Repair Ductwork in a Crawl Space

1. Type of Repair Needed

• Simple Leak Repair Minor leaks can be patched with special tape or mastic for $150–$300. Remember, regular duct tape isn't suitable due to temperature sensitivity.

• Section Replacement Replacing a damaged section of ductwork can cost $500–$3,200. This is necessary if a section is beyond repair.

• Mold or Asbestos Removal Mold remediation ranges from $375 to $7,000, while asbestos removal can cost $450 to $6,000. It's crucial for health and safety.

2. Accessibility Challenges

Crawl spaces are notoriously difficult to work in. Limited access can increase labor costs by 5-10%. The more challenging the access, the higher the labor costs.

3. Size and Length of Ductwork

The size of your system impacts costs. On average, expect to pay about $275 per 10 linear feet. Larger systems require more materials and labor.

4. Material of Ductwork

• Rigid Ducts Made from metal, these are prone to corrosion and can cost $300 to $2,100 to repair.

• Flexible Ducts Easier to install but less durable, costing $100 to $800 for repairs.

• Insulated Ducts Offers energy efficiency, costing between $200 and $1,200 to repair.

5. Labor Costs

General labor costs range from $40 to $80 per hour. Specialized services, like mold removal, can increase this to $50 to $120 per hour.
