If no matter how hard you try, you can’t seem to get the rooms in your home to a comfortable and even temperature, have you ever considered the fact that it could be due to some air leaks in your attic? After all, a well-sealed and insulated attic is what helps to protect your home from harsh weather.

If you’re not sure if you have air leaks in your attic and you’d like a few tips on how to detect and then fix them, you’re in luck. This article is going to provide you with some ways to locate leaks and then repair them, all in a matter of moments.

Inspect your attic. Before you can fix any leaks that may be inside of your attic, the first thing that you should do is inspect it. This would include looking to see if there are any significant holes in your insulation, if you see any cracks around the framing, or if there are any holes in your attic’s access hatch. Also, if you have a chimney, look to see if it or the flues have any cracks. Finally, don’t forget to walk around the various rooms of your house to see if the ceilings have any holes in them as well. This would include anything that penetrates the ceiling, such as pipes, HVAC ducts, and electrical wiring, too.

Plug large holes first. Say that after doing the inspection, you notice a few relatively large holes. In most cases, they are simple enough to fix without the assistance of a professional. What you’ll need to do is go to a local home improvement store in order to purchase some low-expansion polyurethane foam in a can. It’s great for plugging up holes (up to 3″ big) that may be around some of your plumbing or the vents that are connected to your attic.

Plug small holes second. For smaller holes in your attic or ceiling, it’s best to caulk those. If you’re wondering what kind of caulking is the most effective, silicone will be your best bet. The reason why is because it is the kind of material that works well alongside things like metal flashing. Plus, it can withstand the extreme kinds of temperatures that attics tend to experience.

Add more insulation. If you were to ask a professional HVAC technician about one of the benefits of duct sealing and insulation, they would tell you that it helps your HVAC unit to work more effectively. And when your attic is well-insulated, that is one way to keep the rooms in your house at a more even temperature. So if it’s time to replace the insulation that you currently have, make sure to go with an eco-friendly material like sheep’s wool or cotton – also have it around 12″ thick. That is another thing that will help to cover up any air leaks that you may have in your attic. For tips on how to insulate your attic on your own, visit DIY Network and put “insulate your attic” in the search field.

Seal chimney, flues, and access hatch. If there are holes around your chimney or flues, some aluminum flashing can help to repair them. And if you see a couple of holes along your attic’s access hatch, you should apply a bit of weather-stripping. A customer service associate at Lowe’s or Home Depot can show you the right materials to get. As far as how to apply them, This Old House, Bob Villa, and YouTube are all highly-informative websites. Just go to one of them and put “air seal chimney and flues” or “weather-strip” and “attic assess hatch” in the search field.
