"The team at Dana Insulation is top notch. From Tom in sales to the installation team everyone was courteous and professional. They put down protective plastic on the floors so as not to get any dirt or insulation on the floors. Did a great job cleaning up after the job as well. Thank you very much Dana Insulation!!!! I would definitely recommend this company!!!"

"Could not ask for a better experience with a home project. The two young men sent to do the work were most courteous, on-time, professional and thorough in their work keeping us informed of each action and approx. timeline. These young men, and the services performed, truly reflect the service commitment of the owners to their customers like us! We are most pleased with the work and look forward to further benefitting from the work with our insulation needs. Would rehire, if needed. Would, sans hesitation or equivocation highly recommend this service provider - BlownInsulation.comm"

"I spoke with Dan (owner) at Dust Busters who was very professional & honest. He provided a quote, but then explained that it may be less expensive to replace the air duct run rather than replace due to environmental concerns. He provided referrals to other reputable vendors to help. In my experience, he is an honest person who will do what's best for his prospective customers."

"Met with Chad at my home, he was awesome and very professional! Chad was very detailed about all the steps it would take to replace my roof, I honestly felt at ease with him. I was not pressured in any way to go with their company, He assured me if there were any concerns they would quickly resolved those issues and they did. He was very patient, If I had any questions no matter how many he would answer them. I then met my project manager Brian he was awesome as well! If there were any questions or concerns he would answere them with no problem, if there was any problems he would have them resolved quickly. I loved the fact they are really sincere, after signing the contract some companies tend to ignore you and your concerns not Extreme Exteriors they were very professional and stuck to their word. Thank you guys for that! Extreme Exteriors sent their best team to install the roof [ who were awesome!] for my home and garage and my beautiful roof was done in a day. They cleaned up and anything that was not right they corrected. Yes I highly recommend them! I just referred them to several friends and family. Rachel"

"It was the coldest day of the year so far and they still showed up and did the job which was all outside."




Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.
R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.
Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.
You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.
Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
