Ditch the Blankets and Extra Layers of Clothes with the Help of Retrofit Exterior Wall Insulation

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.

Updating Your Exterior Wall Insulation with RetroFoam Injection Foam is a Great Decision for Your Family’s Comfort

Comfortable Rooms

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.

Sound Deadening

Foam insulation in exterior walls can help to deaden the outside noise of loud vehicles, noisy neighbors, and barking dogs.

Reduced Energy Bills

Preventing air leakage improves your home’s energy efficiency, reduces the carbon footprint, and puts more money back in your pocket.

A More Comfortable Home is Within Reach

The easy and convenient install process turns your family’s dream of a comfortable home into a reality - without the stress and mess of a full remodel.

Insulating Your Existing Walls with RetroFoam of Michigan

We’ve been insulating existing homes across Michigan with spray and injection foam for over 15 years. Our consultative estimators, 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.

Wood Siding

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.

Brick Exterior

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 – matching the existing mortar the best we can.
