Insulation questions, answered by experts

Most homeowners installing blown-in insulation as a one-off DIY project should simply rent a blower. They tend to be very heavy, and contractor-grade machines can cost $13,000 to $16,000.

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.

Actually, condensation can mean that your windows are more energy efficient because the seal keeps cold air out and warm air in. In some cases, windows with poor seals can lead to more condensation, but they may allow the cold and warm air to mix and reduce condensation. If you’re worried about whether or not your windows are properly insulated, have a pro assess them.

Insulating your home's exterior walls can realize up to a 20% reduction in your monthly energy bills. This means that regardless of how much the project costs, it can begin to pay you back immediately. Additionally, adding spray foam and other high-end materials can increase the selling value of the property.

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.
