"We are finishing our basement. We put up framing, insulation and paneling only to discover we had a condensation problem. We contacted a locally well known water damage and restoration company. After waiting two weeks, they called to tell us they were not interested in working with us. During these few weeks, we tore down the paneling and insulation.  We contacted Superior Insulation after noticing their great reviews here on Angie's List. We talked to Rick who gave us an idea of what the solution was and set up an appointment to view the problem area. Once he saw the problem area, he decided on a slightly different solution. Contract signed 3/18/15. Work completed  by Rick and Jim 3/30/15. They were very professional, thorough and nice to deal with. We are very happy with what they did.

"Very good. They responded quickly and gave me a quote. They did a great job expediting the work. Their workers were on time and courteous and did a great job. I would recommend them to anyone who needs old insulation replaced with spray foam insulation"

"The crew at Bullseye did a great job adding additional insulation to my attic space. They got my home back up to the proper Rvalue, they also added some vents to help with air flow. Very professional and clean up was great. Can't wait to see the savings on my heating and cooling bills!"

Insulation FAQs, answered by experts

You’ve likely heard the saying “heat rises”—well, it’s true! This is why it is critical to properly insulate your attic and protect yourself from chilly winter nights. During summer, your attic insulation will also protect against excessive heat gain radiating through the ceiling into the rest of your home below.

Exposed ductwork can sweat just like ductwork placed behind walls, sometimes even more so. Ductwork sweats—like a cold drink on a hot day—because of a temperature imbalance between the air in the duct and the air in the room. In a crawl space or wall, this temperature can equalize faster due to the small space but in lofts and open rooms, that wouldn’t happen as quickly. Many people insulate their ducts for this reason.

It improves energy efficiency, reduces noise, enhances indoor comfort, and prevents drafts by filling wall cavities.

If you’re a savvy DIYer around the house, own the basic tools, and have enough time on your hands, you can definitely install fiberglass insulation yourself. Doing the work yourself will certainly keep overall insulation costs down. However, if you’re not confident in your handy skills around the house, call in a professional.

A dehumidifier can reduce condensation on your ductwork by lowering humidity levels in the air. Condensation occurs when humid, warm air makes contact with cold ducts. A dehumidifier can help maintain your home's indoor humidity below or around 50%, minimizing moisture buildup. However, if condensation is caused by leaks, cracks, or other damage, a dehumidifier won’t solve the problem.
