Well fear not, those walls can be insulated without tearing down all the drywall in your home.
RetroFoam of Michigan has more than 15 years of experience insulating thousands of homes across the lower peninsula. This means we understand how to insulate your exterior walls from the outside, without taking down your drywall.
How to Insulate a House Without Taking Down Drywall
There are several types of injection foam available, including the RetroFoam product we use, that don’t require the drywall in your home to be taken down. In fact, injection foam can usually be installed from the exterior of the home, making the installation process quick and easy.
Different types of siding will have different challenges, but the overall goal is to leave as little of a mark as possible.
For homes with vinyl and aluminum siding, a piece of the siding is removed from the side of the home. Holes are then drilled into each stud cavity. The foam insulation is then injected into the cavity.
A good contractor knows when the exterior wall cavity is full by timing the cavity fill, methodical placement of the drilled holes, and feeling the back-pressure on the insertion hole.
Once the cavities are filled, the holes are then plugged with Styrofoam plugs and the siding is replaced.
For brick exteriors, small holes are drilled through the mortar joints between every stud to inject the foam insulation. Once the cavities are filled, the holes are re-mortared to match the existing mortar.
Wood siding tends to be the hardest siding material to work with. If the siding can be easily removed, the same process for aluminum and vinyl siding is followed. If the wood siding can’t be removed, holes must be drilled through the wood siding and filled with wood plugs once the cavity is filled.
The only work the homeowner needs to do is to remove any photos or knick knacks from the walls that could fall off due to vibrations from the drill.
