"Owners did the estimate, were on site for the insulation install...what more can be said about customer service! They were 5+. Now I must tell you about the job...it was difficult adding insulation to the underside of floor boards in our crawl space. Other insulators said it couldn't be done. Kelly took her flashlight, measuring tape and looked really hard and said "We can do this!" What a "can do attitude" and they accomplished it. I will definitely use them again and so should you!"

"Salesman was very professional. Showed up in a vehicle worth the name on the side and in a uniform. Made a video of the bad area of our gutters and explained in detail what problems this would cause and had a very good presentation about the company and product."

Insulation questions, answered by experts

Yes, including recycled denim and cellulose from natural fibers.

Depending on the item, several different materials are beneficial for long-term storage. Bubble wrap and plastic wrap help ensure delicate ceramics or furniture are safe and secure. High-quality moving boxes made of durable materials like plastic also help ensure the longevity of your storage, as cardboard will degrade faster over time.

Yes, insulating ductwork in a crawl space is a worthwhile investment, especially if you live in a colder climate or run your air conditioning for most of the year. Uninsulated ducts can lose up to 30% of their heating and cooling efficiency, which can significantly impact your electricity bill. The project is a relatively small investment and typically only takes a few hours. It's a particularly simple add-on if you are already hiring someone to insulate the entire crawl space. An added benefit is that insulated ducts put off less hot or cold air, making them less attractive to pests.

Fiberglass is the best insulation for HVAC ducting because it's inexpensive, widely available, versatile, and long-lasting. Fiberglass also offers acoustic insulation in addition to thermal insulation, which can contribute to a more peaceful home environment. You can use other materials like mineral wool, but fiberglass is the industry standard.

If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install blown-in insulation. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than $100. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.
