Before Install: Inspection

A contractor should do an inspection of your home’s current insulation. This will give us a good starting point towards understanding what your particular needs are.

Though with wall insulation it can often be impossible to get eyes on the state of insulation itself, due to the walls being closed up and finished. There are still ways to determine if your exterior walls have the proper level of insulation.

4 Phases of Installing Wall Insulation

Taping off stairs

Phase 1: Protecting Your Home

Upon arrival to your home, our installers will begin laying down plastic and cloth tarps anywhere in or around the home they will be working. This includes taping off areas of the home where overspray may occur to ensure a total cleanup after the install.

Phase 2: Preparing Your Walls

Before the installation of new materials can begin we will make sure that your walls are in the best shape possible. This includes installing vapor barriers, when applicable, to prevent the growth of mold or mildew. If we are installing insulation into closed walls this is when pieces of siding will be carefully removed and smalls holes will be drilled into the outer walls. If the old insulation needs to be removed this is when it will be disposed of.

Phase 3: Installing The Insulation

The installation phase will vary depending on what type of insulation you are having installed.

Dense Pack Cellulose Install

Dense Pack

With dense pack insulation, our crew will use a hose to pump the insulation into the wall via small holes drilled on the outside. A blower machine in the truck will break up the insulation and send it running through the hose into your walls. It will be pumped into your wall until it is packed tightly with insulation, creating a dense thermal barrier. Then our crew will seal up the holes created to fill the wall cavities.

Batt insulation


Batt insulation is generally used in new construction and areas where the walls are not sealed. The insulant will be measured and cut to size and fitted between the studs along your wall.  A moisture barrier will be affixed to the insulant to protect your home from water damage.

Closed cell spray foam

Spray Foam

As with batt insulation, spray foam is used on open wall cavities, and like blown-in this insulant utilizes hoses. These hoses will be smaller than the blown-in type and will work in unison to mix and apply the insulant allowing it to cover and expand onto the surface of your attic. Due to the toxic fumes present during installation, it is recommended that your home remain vacant for a full 24 hours after installation.

Cleaning up after install

Phase 4: Clean Up

Once your attic insulation has been installed the crew will begin removing the protective barreirs they put up in phase 1. They will take care during this process to avoid dropping an overspray in or around your home. Any insulation that was missed by the protective layer will be cleaned up. Leaving your home as clean as we found it.
