Ductwork testing

A special test for your ductwork can help you find and fix leaks, and save money.

Fixing the leaks

You can seal your ductwork yourself using metal and foil-reinforced tape or mastic, which is a fiber-reinforced paste. Alternatively, a professional can use aerosol sealants to seal the ductwork internally. Tip: remember to leave your furnace filter slot or the combustion air inlets in your HVAC system open and unsealed.

Sealing from the inside out

There are many ways to seal exposed ductwork, using mastic or special foil tape, but what about inside your walls? Check out this product that seals the holes from the inside out.
