With poor insulation in the exterior walls, Michigan homeowners could be experiencing several problems with comfort and high energy bills in their homes.
Sign and Symptoms Your Exterior Wall Insulation May Need Updating
If you are experiencing any of the following problems, it may be time to consider updating the insulation in your exterior walls.
- Rooms in the house that are too hot in the summer and too cold in the winter.
- The walls have original insulation from when the house was built decades ago.
- High energy bills.
- Uncomfortable drafts.
- Walls cold to the touch in the winter.
- Dishes are cold inside kitchen cabinets in the winter.
- No insulation in exterior walls (hard to believe, but we’ve seen it).
What’s Currently Inside Your Walls?
It is hard to imagine that some homes in Michigan don’t have any insulation in their walls. Some builders discouraged this “added expense” in previous decades, and homeowners have experienced some of the symptoms above as a result.
On the opposite end of the spectrum, we’ve assessed plenty of newer homes built in the last 10 years that although up to code are also experiencing comfort issues and high energy bills. This is caused by poor insulation since traditional fiberglass insulation is known to break down over time, hold in moisture and dust, and doesn’t offer an air seal.
The Best Exterior Wall Insulation
Many people think they would have to tear down their drywall or go through a complete remodel down to the studs to update the insulation in their walls. Not only would this be a messy and expensive project, but would also take several weeks to put your house back together.
However, there is a method for retrofit wall insulation that is quick, simple, and typically installed in just one day using RetroFoam injection foam. Not only is the install process perfect for existing homes, but the foam insulation will act not only as an insulator, but also as an air seal to fill in all the nooks and crannies in your walls. This will help reduce pesky drafts and keep your house a comfortable temperature all year.
Installing Foam Insulation in Existing Walls
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” 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.
Injection Foam Insulation Cost
At this point you may be wondering how much foam wall insulation costs.
As you can imagine there are many factors that determine the injection foam insulation cost. The size of the area to be insulated is a big factor, along with other aspects such as your siding type and if the home is one or two stories. That being said, the majority of the retrofit wall insulation jobs we complete are in the range of $3,000 to $7,000 before any applicable discounts and rebates from participating energy providers.
