Home remodeling projects can be huge undertakings, making it crucial for homeowners to entrust their projects to reputable and experienced contractors.


As a contractor, you know how important it is to provide your customers with top-notch building materials.

Insulation, Shower Doors, Garage Doors, and More Throughout the Southeast

When it comes to getting quality home improvements for yourself or your customers, you need a company with a long-standing reputation for exceeding expectations. When we started 31-W Insulation in 1972 in Millersville, Tennessee, we didn’t envision it would become the second-largest insulation company in the Southeast with more than 800 employees and 48 locations in 12 states. We only knew that we wanted to treat people with respect and provide the best in insulation and other home remodeling services. We still remain under family ownership while being self sufficient in almost every aspect of our services, including having our own truck fleet.

We serve contractors working with both residential and commercial customers, and we also deal directly with the public. Our products and services include bath accessories, garage doors, gutters, insulation, and such home remodeling projects as fireplaces, blinds, shelving, door hardware, and closet systems. We also have a wide variety of top-of-the-line building materials if you are a contractor wanting a reliable source that will fit your customers’ needs.

You’ve come more than highly recommended from a contractor with Frierson. Brian Hunter came out today and I had to cancel my next two appointments for estimates. I was IMPRESSED, and you’re HIRED! Thank you!

We needed insulation in our attic. We got a quote, scheduled a date and time, and they even arrived a little early. The guys who did the install were very friendly and speedy. A+ experience.
