"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

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.

Energy-efficient homes generally have higher appraisals and appeal to buyers.

Single-pane windows might let in the cold, but if you’re not ready for a long-term solution or window replacement, there are quick fixes to keep your space warmer. Start by sealing gaps with weatherstripping or caulking around the frame to block drafts. For an extra barrier, apply window insulation film to the glass, trapping an air pocket between the film and the window. Thick curtains or thermal drapes can also help keep the chill at bay. And if you’re in a pinch and looking to get creative, bubble wrap can provide a surprisingly effective layer of insulation—just spritz the window with water and press it on, bubble side in.

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.

Expect your home insulation project to take between five and 12 hours to complete on average for batts or boards and two to five hours for spray foam or blown-in insulation. It might take longer if you need to remove your home’s existing insulation, you have a higher-than-average square footage, or accessibility is limited.
