"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!!!"

"From the consultant, Joe, to the five men that came to my home, I was impressed with the professionalism and respect for my home. Tyler,Jake, Chuck, Dustin and Scott made sure everything was installed with exceptional precision and attention to detail. It took a full day to accomplish. They arrived on time, and cleaned up afterwards throughout my home and garage. Protective covering on their feet with additional protective materials on my floors and walls were used. Their care and respect went above and beyond. The product is eco friendly, fire retardant and mold resistant. And my home is warm and cozy. Removing all the old and filthy insulation that is 37+years old and leaving my attic space and foundation areas sealed and cleaned just makes everything feel buttoned up and tight. Highly recommend! Special shout out to Makaila and Katie, office personnel that kept in touch and applied for eligible rebates to help keep costs down as well. Thank you!"

"I hired Thermal Solutions to spray foam insulate my pole barn and they did an excellent job. I got 4 quotes and theirs was the cheapest. They say never go with the cheapest, but I did because I wanted to support a veteran owned, local business, and after talking with Niko, I felt confident the job would be done right. I'm really glad that I did because they came when they said they would, they did it just the way that I wanted, and they did a great job of cleaning up when they were done. I highly recommend them for open and closed cell spray foam insulation jobs!"

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.
