When a home is tightly sealed it can, not only help to improve the air quality and comfort inside the home, but it can also lower the amount you spend on utility costs as well. Another benefit is that the majority of homeowners can do these small jobs themselves.
One area of the home that may warrant particular attention with regard to sealing and insulation is in the attic space. As we know, hot air rises which means air leaks are more likely to happen in the attic. If you notice large holes these will need to be plugged. Areas where you might notice the biggest leaks are dropped ceiling areas, behind or under attic knee walls, and where the wall meets the attic floor. Smaller holes will need to be sealed up. You should find that these areas are pretty easy to notice because insulation may become darkened. The attic access panel is another place that you should seal, which you can do with weatherstripping or foam board insulation.
What other parts of the house may need sealing or insulating? As we have stated, attic hatches are one area. Here are some others, electrical outlets or receptacles, window frames, baseboards, doors, around pipes, and window or wall mounted air conditioning units.
Yes, assessing your home for areas that are in need of insulating and sealing is one way to save on your home's heating and cooling costs, making it a lot more energy-efficient.
