Services
Spray Foam Insulation
Spray foam insulation creates airtight seals in attics and crawlspaces. This high-R-value solution expands to fill gaps, preventing air leaks and improving energy efficiency. Ideal for hard-to-reach areas, it also acts as a moisture barrier to prevent mold growth while conforming to irregular spaces.
Cellulose Insulation
Made from recycled materials, cellulose insulation reduces noise and improves thermal performance. It effectively maintains comfortable temperatures year-round while offering an environmentally conscious option for attic and wall insulation projects in residential and commercial buildings.
Insulation Removal
Our team safely removes damaged or outdated insulation using protective equipment and specialized tools. We contain contaminants, clean affected areas, and prepare spaces for new insulation installation to restore energy efficiency and indoor air quality.
Attic Insulation
We install and upgrade attic insulation to meet R-value requirements for Indiana's climate. Services include assessing existing insulation, recommending materials, and implementing solutions that reduce energy costs while improving home comfort and structural integrity.
Energy Efficiency Assessment
Our experts evaluate current insulation performance, identify air leaks, and recommend improvements. This assessment helps homeowners understand where energy losses occur and what upgrades will yield the greatest savings on heating and cooling bills.

We would highly recommend D&N to anyone! After a different company kept postponing our appointments, we gave D&N a call and they came out very promptly to do an estimate. Within about 3 weeks they were able to get us in and added insulation to our attic. Everyone on the team that we encountered was very professional. They were very thorough, going above and beyond to make sure that the job was done correctly; they even installed some ventilation for our bathroom fan when they discovered it didn't have any. It's been about a week now and the extra insulation has made a huge difference!

Highly recommend D&N Insulation - Great people to work with, responsive, competitive pricing, and a great local family run business worth supporting. I had BAD ice dams due to insulation issues, they were well experienced in assessing my issues and then completing the job to fix. Definitely recommend them.
