Air sealing attic plumbing pipes | DIY home improvement tips | Rule Your Attic! With ENERGY STAR
Learn how to identify a plumbing pipe/plumbing vent in your attic and seal air leaks around it. Plumbing that penetrates your attic floor can have gaps around them and leak air. By sealing these gaps, you can save money, save energy, make your home more comfortable, and reduce the emissions that contribute to climate change. It’s easy to do yourself.

Here are the steps to seal the leaks around your plumbing pipes/plumbing vents:
1. Carefully enter your attic (for safety you may want to lay a piece of plywood across the floor joists to stand or kneel on) and identify the plumbing pipe (vent). The pipe will be made of either plastic or cast iron – and it shouldn’t be hot to the touch! If it is, it’s a flue and not the pipe you want to seal!
2. Once the pipe is identified, push back the existing insulation around it.
3. Once the existing insulation is pushed aside, look for gaps between the pipe and attic floor.
4. If the gaps are large, stuff fiberglass insulation into the gaps so the spray foam does not fall in.
5. Then, apply spray foam over the gaps around the pipe and let the foam dry and cure for at least 30 minutes.
6. Once the foam is dried, replace existing insulation over foam.
7. You’re done with this step! Now there are a couple of other things you can do to improve your home’s energy efficiency:
