How To Avoid 4 Common Wall Insulation Mistakes

Most of us don’t spend a lot of time thinking about what’s behind the walls of our homes. Yet a lot rides on whether the original construction crew who helped build your home knew what they were doing.

With proper wall insulation, your home will stay warm in winter, cool in summer. Without adequate wall insulation, air leaks out of your walls, making your home anything but efficient. That’s why it’s important to go back and determine if the job was done the right way the first time.How To Avoid 4 Common Wall Insulation Mistakes

The good news is you can add wall insulation to help make your home warmer and more energy efficient. But before you say “yes” and start the process, there are a few things you should know.

More is better

Insulation isn’t a one-time maintenance item. What was installed when your home was built isn’t what’s best for your home long term. As time goes by, insulation settles. Requirements and building codes have changed. If you feel drafts or cold/warm spots in your home, it means there are parts of your home that need more insulation. The more insulated your home, the more regulated the temperature will be. Every wall should be checked for adequate insulation. Don’t forget doors, especially between the garage and your home. Floors and ceilings between different levels of your home are important too.


R-value tells you the insulation quality you’re about to install. The higher the R-value, the better it will insulate your home. Even low grade insulation will have some protection. But if you’re going to all the trouble of adding insulation, why not ensure you’re making your home as efficient as possible?

Old insulation

Don’t assume that you have to replace old insulation with new. As long as your current insulation is still in good condition, you can add new insulation over the old. Think of it as adding another blanket to your bed on a cold night. New wall insulation simply adds in more protection.

Covering up problems

Adding new insulation shouldn’t be done blindly. If you’ve noticed drafts and cold/warm spots in your home, it’s a good idea to find the reason why. Are there gaps by windows, doors, or joists that allow air movement? Has moisture seeped in? Be sure to fix whatever problems exist, replacing damaged insulation before you add in the new.

Can wall insulation make a difference in your home? Yes. It can be one of the most crucial home improvement jobs you take on this year. To increase efficiency and make your home a more comfortable place to live.
