You are sitting in your home during the winter and feel an annoying, cold draft. Unfortunately, nobody forgot to shut the door - it is just another day in an uncomfortable home with insufficient or no wall insulation. Insulating the exterior wall cavities with RetroFoam injection foam will compress any old insulation in the walls and seal up the area to prevent air leakage - helping to reduce drafts, keep rooms more comfortable, control energy costs, and deaden outside noise.
Foam insulation fills all the nooks and crannies in existing walls to provide the necessary air seal to reduce drafts and keep indoor temperatures consistent.
Foam insulation in exterior walls can help to deaden the outside noise of loud vehicles, noisy neighbors, and barking dogs.
Preventing air leakage improves your home’s energy efficiency, reduces the carbon footprint, and puts more money back in your pocket.

Our process for retrofit exterior wall insulation is quick, simple, and typically installed in just one day. Most walls are insulated from the outside, but we can also inject foam into walls from the inside if needed. However, the install process is slightly different depending on the home’s siding type.
A strip of siding is removed from your home and holes are drilled between the stud cavities. After injecting the foam insulation in the cavity we plug the hole, put your siding back on, and clean up any excess foam.
Depending on the condition and make of your wood siding, we may be able to remove it and follow the same process we do for vinyl and aluminum siding. If we aren’t able to remove it, we would drill through the siding to inject the foam, then plug the hole with a tapered wood plug.
We can also insulate through a brick exterior without removing any brick.
Our installers drill ⅝ inch holes through the mortar joints to inject the foam insulation, and the holes are re-mortared upon completion using a standard gray mortar.
Concrete block walls can be insulated by using either spray foam or injection foam, depending on the look the homeowner wants to accomplish.
The foam can be sprayed directly on the concrete wall, or in some cases, it can be injected into the cores of the concrete blocks.
