Can you have too much blown insulation?

But there may be a theoretical point of “too much.” If a home is over-insulated and is too tightly sealed, moisture can get trapped inside. Without proper ventilation, a home can build up too much moisture, especially in the attic (warm air rises), which can cause mold problems and, overall, lower indoor air quality.

As hidden as insulation is behind the walls, up in the attic and under the floorboards, its benefits are not as veiled! You probably know by now (especially if you’ve read our blog before) that the right amount of insulation can help reduce energy bills and improve comfort all year round. The key words there are “right amount.” If your home is not properly insulated, you’ll have a much harder time-saving money and staying comfortable. A house can definitely be under-insulated (millions of homes throughout the United States have this very problem), but can it have too much insulation? In short, yes it can!

Can You Over-Insulate Your Minneapolis Home?

Homes need insulation, and more is generally a good thing. But there may be a theoretical point of “too much.” If a home is over-insulated and is too tightly sealed, moisture can get trapped inside. Without proper ventilation, a home can build up too much moisture, especially in the attic (warm air rises), which can cause mold problems and, overall, lower indoor air quality. This is not to say that if you have mold in your home, too much insulation is the culprit. Most homes and buildings in Minnesota—and across the country—are under-insulated. Dampness and mold issues in a home have a number of more common causes, such as an old or malfunctioning HVAC system (sometimes a dehumidifier is the solution), broken sump pump in the basement or leaking pipe. But if you’re noticing anything off, a home insulation inspection can be worth it! There’s a small chance your home may be over-insulated, but there’s a much better chance you don’t have enough insulation, particularly if you’ve noticed:

Higher than normal energy bills (without an increase in usage)

Drafts or uneven temperatures from room to room

Unusually warm second floor in your home

This is why we don’t recommend DIY projects—professional jobs help ensure materials are installed correctly and safely and the right amount of insulation for maximum energy savings and comfort.
