"I have an old brick ranch and the insulation in the attic was still original and long overdue to change. Mark and his team did an excellent job. Not only he offered the best price, but he offered the full range of necessary small fixes that made a huge difference. Mark and his team take pride in their work. I highly recommend Insulation Commandos for your future projects."

"⭐⭐⭐⭐⭐ Outstanding Blown-In Insulation Installation I had an excellent experience with National Energy Solutions for a blown-in insulation installation in my garage. From start to finish, the process was professional, efficient, and stress-free. The team arrived on time, clearly explained the work they were doing, and completed the installation with great attention to detail. The blown-in insulation was installed evenly and thoroughly, and they made sure everything was clean and orderly before leaving. You can immediately tell they take pride in their work. What stood out most was their customer service. They were respectful, knowledgeable, and patient in answering my questions. The improvement in temperature control in my garage was noticeable right away, and I feel confident the insulation will make a long-term difference in comfort and energy efficiency. I highly recommend National Energy Solutions to anyone looking for quality insulation work done right the first time. Professional"

Customers say: Terrific value

"Danny insulated our home that was built in the late 70's and our electric bill was cut by more than 1/3! He did excellent quality work, was done when he said he would be done, kept a very clean jobsite and we have nothing but great things to say. We are planning on using him on our new build very soon."

Insulation FAQs, answered by experts

Completing insulation service in Kennesaw enhances home comfort by maintaining consistent indoor temperatures and reducing drafts. Improved insulation lowers cooling demands during hot summers, keeps floors warmer in winter, and helps manage indoor humidity. It also reduces outside noise and blocks allergens, boosting air quality. These upgrades make your home quieter, healthier, and more energy efficient—key benefits in Kennesaw’s variable climate.

Helpful?

In Kennesaw, new homeowners should prioritize attic insulation, aiming for an R-value between 38 and 49 for optimal energy efficiency. Next, seal air leaks around windows and doors, insulate ductwork in unconditioned spaces, and add vapor barriers in crawl spaces or basements. Addressing garage ceilings and attic hatches can also provide unique comfort improvements, especially in homes exposed to direct sun or high humidity.

Helpful?

For insulation service in Kennesaw, keep essentials like a digital thermometer, flashlight, measuring tape, utility knife, and staple gun. Stock up on dust masks, safety goggles, and work gloves for protection. Weatherstripping, caulk, foam sealant, plastic sheeting, spare insulation, and aluminum duct tape are crucial. In Kennesaw’s humid climate, a dehumidifier, mold prevention spray, and pest deterrents help maintain insulation performance and home comfort.

Helpful?

Your Kennesaw home is a strong candidate for insulation service if you notice high energy bills, uneven temperatures, or persistent drafts. Homes built before 1980, those with visible attic joists, or signs of moisture like mold or condensation are especially good prospects. In Kennesaw, homes near wooded areas often benefit from pest-resistant insulation to address local wildlife concerns, further improving energy efficiency.

Helpful?

In Kennesaw, insulation service success relies on proper air sealing, choosing the correct R-value for the local climate, and ensuring quality installation. Moisture control and good ventilation are critical due to humidity. Using pest- and mold-resistant materials helps extend insulation lifespan. Regular inspections and addressing attic or crawl space leaks also support long-term energy efficiency and comfort in your home.
