DIY Home Insulation Pros
Fiberglass batts and rolls are fairly inexpensive and can be installed in open and accessible areas like attics, crawl spaces, and rim joists by the handyman homeowner. The homeowner can install blown-in cellulose insulation, but a machine must be rented for the installation.
Cost-Effective: Compared to other insulation types, blown-in insulation offers a budget-friendly solution. It requires fewer materials and is quicker to install, which means labor costs are lower. This makes it a great option for homeowners looking for an affordable way to improve energy efficiency.
Little to no insulation in your crawl space is letting all of that outdoor air into your home, making it uncomfortable and in some cases unhealthy. Insulating your crawl space with spray foam can stop those cold floors plus drafts around the floorboards, freezing pipes, as well as moisture and mold issues.

It is possible to over-insulate your house so much that it can't breathe. The whole point of home insulation is to tightly seal your home's interior. But if it becomes too tightly sealed with too many layers of insulation, moisture can get trapped inside those layers. That's when mold starts to grow.
On a winter day when it's cool and rainy outside, go around and touch parts of your home, like the interior ceilings, walls, and floors. They should all feel warm and dry. If the drywall and paneling in these spaces do, that's a great sign that your home is well insulated.
About 35% of the heat will escape through the walls and through gaps, in and around windows and doors, and about 10% of heat will disappear through the floor. Taking action to make sure your home is energy efficient has many benefits.
Age 👴🏼 – Insulation is typically pretty hearty. For most homes, it can last for 20-80 years! That being said, like all things, insulation tends to wear down over time. If you are living in an older home and encountering some of the following problems, it may be time for a replacement.
Internal insulation can be fitted when you're planning to redecorate anyway, or to fit a new kitchen or bathroom. You can also spread the cost by tackling one room at a time. External insulation will also cost less if you fit it when you're having other work done to the outside.
