Crawl Space Duct Sealing and Insulation
Ducts that leak or hang loose in a crawl space waste energy and pull in damp air. We seal joints with mastic or foil tape, insulate the ducts and support them off the ground, so conditioned air reaches the rooms.

Questions
About crawl space duct sealing and insulation
How much energy do leaky ducts waste?
It can be significant, because leaked air never reaches a room. Sealing helps the system do its job.
Do duct repairs need an HVAC technician?
Sealing and hanging we do ourselves. If the system itself needs repair, we point you to an HVAC specialist.
