        How to Fix AC and Dryer Pipe Leaks

        Follow these instructions to seal off leaky AC and dryer vent pipes.
        • Time

          Weekend

        • Price Range

          $100 - $250

        • Difficulty

          Moderate to Hard

        In this Project you will:

        Step 1: Saw the Drywall

        Lay down a drop cloth and begin squaring off the hole in the ceiling using a drywall saw.

        Step 2: Seal the Holes

        Next, seal the holes in the vents with aluminum tape.

        Step 3: Redirect the Vents

        Separate the AC and dryer vents as much as possible and secure them into place.

        Step 4: Patch Up the Ceiling

        Now you can patch up the hole in the ceiling. Begin by cleaning up the edges by removing any spare screws. Measure the drywall and cut it to size (Image 1). Screw the drywall in place (Image 2).

        Step 5: Seal the Drywall

        Apply the first layer of drywall mud to create a seal. Allow it to dry completely, sand it down, and repeat as needed. To complete the project, prime and paint the ceiling.
