"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.

"I recently needed attic insulation installed; I reached out to several companies for quotes. Dallas came out right away and gave me a complete honest rundown on my issues. I had just purchased this home only to understand my situation was dire, he gave me a great price and even offered to change his schedule to get this project done quickly. He showed up within just a few days and did an incredible job, his team is very professional and even installed a new bath fan i needed. Thank You Windsor Insulation company, my house is noticeably warmer and I couldn't be happier. Great Job and I recommend Windsor Insulation 100%"

Insulation questions, answered by experts

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

If you have access to the foundation walls, adding spray foam insulation to your existing unfinished basement or crawl space is straightforward. Replacing existing insulation in your unfinished attic space is possible after removing the old insulation. However, spray foam insulating an existing wall after the drywall is in place isn’t possible unless you remove most of the drywall.

The primary purpose of insulation is to maintain comfortable temperatures in a home, whether that’s cool air when it’s hot out, or warm air in winter, but that’s not all it can do. All options will also minimize heating and cooling needs, lowering both your carbon footprint and energy bills in turn. And some options, like rigid foam boards, even offer soundproofing benefits, too.

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.

Blown-in insulation works, but only for unfinished attics. Also, it isn’t the longest-lasting nor the most effective option. For better options, look into spray foam insulation or natural fiber batts. They typically have a longer lifespan, better heat resistance, and stronger sound-proof abilities. Spray foam insulation costs about $1.25 to $1.50 per square foot, but can go up to more than $4 per square foot. Fiber batt pricing varies depending on the material.
