Insulating Your Existing Walls with RetroFoam of Michigan
We’ve been insulating existing homes across Michigan with spray and injection foam for over 17 years.
Our consultative project managers, highly skilled crews, and helpful office staff aim to guide you through the whole process with ease. Also, our lifetime warranty gives your family access to our family long after the job is complete.
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.
Vinyl and Aluminum Siding
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
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.
