Insulation & Air Sealing


Greenwald & B.C. Inc. serves clients throughout Central and Northern Michigan, including Mt. Pleasant and Beaver Island. If your energy bill consistently seems to be too high, or you aren’t as comfortable as you would like to be, odds are you have insulation voids within your home. Whether your home is old or fairly new, the need for an insulation audit is something that any homeowner can benefit from. Today’s homes are built using advanced techniques including high performance insulation’s, air sealing materials, and testing to ensure that the homes thermal envelope is sufficient and is effective. Not long ago, this was not the case. Greenwald & B.C. provides testing services to many builders in the area, helping them build better and learn from mistakes. We have been performing blower door testing since 2009, long before it was required. Our time providing these services has shown us what works well and what does not.


We have the ability to come into your home, find those voids, seal the air gaps. or add insulation, depending on the scenario. Having a properly insulated home will keep your home warm in the winter, and cool in the summer. This will save you money on your energy bill and keep you more comfortable year round. After all, isn’t comfort what we count on at home? Schedule a time for us to evaluate your home to determine if we can help you make improvements in the thermal efficiency of your home. We can help you decide what corrective measures are most affordable for you and your family.
