Home > Insulation, North Charleston, SC

We are the second largest insulation contractor in the southeast!

It might surprise you that up to 90% of the homes in the United States, including those here in the North Charleston, South Carolina area, do not have adequate insulation to enjoy optimal energy efficiency and comfort. While your home might have the bare minimum to keep your plumbing from freezing and ice forming on the roof, you could be spending hundreds of dollars a year on heating and cooling that could be avoided with an investment into upgrading or replacing the insulation. At 31-W Insulation, we have been the trusted source for quality insulation products and services since 1972 and have become the second largest insulation company in the southeastern United States.

Insulation contractor hands with gloves doing it's job

You can rest assured that whether you come to us as a homeowner looking to have your home’s insulation assessed or as a contractor in need of an insulation professional for your residential and commercial projects, you will be more than satisfied with our professionalism, integrity, products, and workmanship. We also do more than just insulation, so don’t hesitate to ask us about our other improvement products and services.

One of the ways we excel as an insulation contractor is in our willingness to offer several different types of insulation products and take the time to fully explain them to you, so you can make an informed decision about what is best for your situation. We are happy to make a recommendation based on our years of experience as to whether batt insulation, spray foam insulation, or blown insulation will give you the results that fit your objectives and budget.

You can count on us for an accurate assessment of your home and an honest recommendation as to whether you could benefit enough from an insulation upgrade to warrant the investment. Chances are that if you have an older home, you can save considerably on utility costs, but even newer homes often see improvement  with added insulation because home builders don’t always use the best products as they try to keep costs down as much as possible. We recommend calling us to schedule an inspection of your home’s insulation if you’ve noticed an increase in your utilities that is not related to other factors, you notice cold and hot spots, you have difficulty being comfortable no matter what you set the thermostat at, notice moisture in the attic, or experience ice dams during the winter. In addition, if you’ve recently had a pest or rodent infestation, it is a good idea to check to see if they damaged the insulation during their stay.

If you have any questions about insulation for your home or need an insulation contractor for your construction business, don’t hesitate to reach out to us. We are happy to meet with you and conduct an inspection so you can know for certain whether you fall into the 10% that has sufficient insulation or the 90% that do not. Feel free to ask us about other improvements, as well, including garage doors, gutters, fireplaces, and other home remodeling products.
