The Unexpected Surprises of Blown-In Insulation Installation

By Team March 13, 2023

If you're a homeowner looking for an efficient and cost-effective way to insulate your home, blown-in insulation might be the answer. It's a popular insulation method that involves blowing tiny fibers or particles into walls, ceilings, and floors. While it's relatively easy to install, there are a few surprises that homeowners might encounter. In this article, we'll explore some of the most unexpected things you should know before installing blown-in insulation.

The Mess

One of the most surprising things about blown-in insulation is how messy it can be. The installation process involves blowing tiny particles of insulation through a hose into the walls, which can create a lot of dust and debris. The installers will use tarps and other protective gear to minimize the mess, but it's impossible to eliminate it completely. Be prepared to do some cleaning up afterward.

The Noise

Another unexpected thing about blown-in insulation is how noisy the installation process can be. The blowing machine is loud and can be heard throughout the house. If you're sensitive to noise, you might want to consider leaving your home during the installation process or using noise-canceling headphones.

The Smell

Blown-in insulation can also have a distinctive smell during installation. It's not necessarily a bad smell, but it can be strong and linger for a while. The odor is usually caused by the chemicals used to treat the insulation to make it fire-resistant and insect-proof. The good news is that the smell will eventually dissipate, but it might take a few days.

The Dust

Blown-in insulation can create a lot of dust, which can be a problem if you or anyone in your household has allergies or respiratory issues. The dust can irritate the lungs and cause coughing or sneezing. The installers will do their best to contain the dust, but it's still a good idea to prepare for it by wearing a mask and keeping the area well-ventilated.

The Settling

Another thing to keep in mind is that blown-in insulation can settle over time. This means that the insulation won't be as effective as it was initially. To prevent settling, you should make sure that the insulation is installed to the proper density and depth. You can also have the insulation checked periodically to make sure it's still doing its job.


Blown-in insulation is an excellent way to improve your home's energy efficiency and save money on your heating and cooling bills. However, it's important to be aware of the surprises that can come with the installation process. The mess, noise, smell, dust, and settling are all things that homeowners should be prepared for. If you're considering blown-in insulation, make sure to do your research, ask questions, and hire a reputable installer.
