"We called Mister Insulation and Jeff came out in a day or so. We explained that we purchased new windows and doors and had insulation blowen into the walls but the house was still not warm. He took pictures in the attic and used a thermal camera to show where we were losing heat also we had mold. He removed the mold and replaced the insulation . He and his crew were very professional. We would recommend them ."

"They did an incredible job. Took out all the blown in insulation and spray foamed whole attic. Making it a useable space for storage and helping to regulate the temperature in our home. Will be calling on them for future projects."

"The workers did the work well. I added more attic insulation, install walkways in the attic, seal our two crawl spaces My only issue was the salesman would never get back to us with the before and after air tightness results. I wrote down the raw numbers when the workers did the air tests, but they promised 6 times that the salesman would get back to me on the final results and impact it should have on our bills. Workers great, office terrible."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"They also did insulation in our attic , the roof was done in 1 day which is standard and the workers were very efficient and cleaned up very well after themselves. Everything from beginning to end was top notch , the company went above and beyond from the thank you card we received shortly after signing up with them , to a detailed letter of what to expect . Our roof was installed within 2 weeks, and the insulation was done a week later. We were kept up to date with the progress of each part of our projects. We would highly recommend them and will be using them again for more work we need done. Thank again"

"They custom make the windows and Fed-Ex them to you. We installed them ourselves to save money. Once we put them in, we couldn't hear outside noise anymore. It made a world of difference. I think it has also helped insulate my home a little. For the cost, I think it would have been twice as much to have the windows replaced."

Insulation questions, 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.

Through R-value assessments based on climate and existing insulation.

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

The best R-value for home insulation depends on where you live and where you’re installing the insulation. Your climate zone plays the biggest role in determining the correct R-value, so be sure to know which zone you live in when determining the R-value you need.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses.
