DIY Duct Sealing and Leak Repair
DIY duct sealing can be a cost-effective option for minor leaks and accessible ductwork. Homeowners typically use materials like mastic sealant, foil tape, or duct sealant to patch visible gaps. It works best when the issues are small and easy to reach, and it allows for immediate action without scheduling or labor costs. However, DIY methods often miss hidden leaks inside walls, ceilings, or complex duct systems. Without proper tools like pressure testing equipment, it’s hard to ensure a complete seal. This can lead to ongoing energy loss and reduced HVAC efficiency over time.
