"I would 100% recommend Matt and his company, Add More Insulation, to friends and family. We had a fairly straight forward job of adding additional insulation to our attic. Matt came in at a fair price and importantly, he arrived on time for his estimate appointment and for the project appointment itself. We have also already noticed that the insulation has worked to keep it cooler in our second floor as we had hoped. A+"

Insulation questions, answered by experts

Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks. Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line.

Depending on where you live and the conditions of your basement, you may not need to insulate your basement. Your best bet is to talk to a basement remodeling company to find out what they recommend doing.

Insulating your basement can help improve your home's energy efficiency, but it will also increase the cost of your basement remodel project. The average cost of installing basement insulation is $2,400.

Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they’re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.

Not necessarily. A higher R-value simply means that the insulation has a higher heat resistance and performs better in terms of how much heat passes through the material. This can be better for some homes, or it can be too high of an R-value for other homes. Again, your climate zone determines whether the insulation is better for your home.

How to dispose of insulation depends on a few factors, including the condition of the material. While you can simply bag up and throw away many kinds of insulation, some municipalities offer recycling, so it's worth checking with yours. If there are contaminants such as asbestos in your insulation, abatement and specialized disposal are often necessary.
