Air duct repair and sealing in Whittier

Signs of a duct problem

• One room is always too hot or too cold
• Weak airflow from certain vents
• Noise or whistling near a vent
• Visible tears or sagging in the attic or crawl space
• Insulation or debris coming from a register

Repair or seal?

Sealing suits small leaks and gaps at accessible joints. A section that is crushed, badly torn or wet usually needs replacing. Insulated duct that has become wet or moldy should be removed, because it cannot be cleaned effectively.

Sealing leaks is different from coating

We seal air leaks at the joints and connections. Spraying a coating inside ducts is a separate practice with its own trade-offs, and we would only discuss it with you first.
