There are so many benefits to sealing your air vents beside the financial savings, and I’m going to show you those benefits later on. But first, here is a step-by-step guide for sealing your vents.<\/p>\n\n\n\n
1. Inspect the vents<\/h2>\n\n\n\n
Usually, it is impossible to visually tell that a duct is leaking, but there are several other ways that you can tell. One of the easiest ways is to inspect the vents and air returns to see if there are any cracks in the ductwork that leads to them.<\/p>\n\n\n\n
If there are cracks in the ductwork or gaps between the floor and the duct, then the duct is leaking and the air is escaping from it. Sometimes, you might be able to hear a whistling sound which can also indicate that there is a leak in your ductwork.<\/p>\n\n\n\n
2. Gather your supplies<\/h2>\n\n\n\n
You will need the following to seal your air vents:<\/p>\n\n\n\n

- Scissors<\/li>\n\n\n\n
- Caulk<\/li>\n\n\n\n
- Expanding foam (for larger cracks)<\/li>\n<\/ul>\n\n\n\n
3. Caulk<\/h2>\n\n\n\n
To fix the crack in your air vent you will need to put a thin line of caulk between the ductwork and the plasterboard. If you have a large gap then you will need to use expanding foam to mend it.<\/p>\n\n\n\n
You’ll need to take care if you are using expanding foam as it can be hard to remove from plasterboard if it gets onto it, and it can be quite messy to use.<\/p>\n\n\n\n
4. Insulating strips<\/h2>\n\n\n\n
You can make your air vent more energy-efficient and reduce the amount of air infiltration by adding weatherstripping to the underside of the air vent. Quite often, builders don’t add these strips even if the air vents have already been caulked.<\/p>\n\n\n\n
