Can You Put New Insulation Over Old? St Charles, MO

Reduce Energy Bills & Improve Comfort

The answer is, it depends. We’ll get more in-depth on that in a minute. But first, there’s no doubt that adding new insulation to key areas of your home helps to reduce your energy bills and carbon footprint while increasing your comfort. Most homes in Missouri have insulation in the walls, basement and attic, but extra insulation can offer even better results.

Proper installation is just as important as amount, which is why you should call a St. Louis insulation contractor for help. Sometimes it’s possible to keep your current insulation while adding more.

When is Keeping Old Insulation a Good Idea?

The only instance where keeping your old insulation underneath the new is if it’s still in good condition and you just want to augment the amount. If contamination has occurred, whether through water, smoke, mold, or pest droppings, you should not add new material over old Again, this is why a professional inspection is so important. Your contractor can determine if your existing insulation has sustained damage in any way and if it’s best to just remove it first before adding new materials.

When Should You Remove Old Insulation?

If you are looking to add fresh material, the underlying insulation can’t be wet, damp or previously-wet. Whether from a roof leak or a busted pipe, water can soak the insulation and become a breeding ground for mildew, mold, and insects. Removal is necessary if the insulation is wet or moldy. Putting new material on top of that doesn’t make financial, health, or efficiency sense.

At the same time, you have to find the root cause of the moisture and resolve it so it doesn’t keep happening to the new insulation. If the moisture is coming from a roof leak, you may have to call a roofer first to address that situation before your insulation contractor does his job.

Adding new insulation will depend on whether your old insulation is water damaged. If the current insulation is dry, and has never had water damage in the past, it’s OK to add fresh insulation on top.

You may assume that adding new insulation is a DIY job, but it’s not. It’s best to let a professional insulation contractor in St. Charles handle the installation for the best results. They will take the proper precautions to ensure the insulation is handled and disposed of safely.
