"I called several professional insulators. He was the only one to return a call and do the job. Not only did he get the job done when he said he would he wasn’t happy about how he did around the attic opening he returned a couple days later and did it like a professional insulator would do. I would definitely recommend him and his company. Thanks again Reuben it was a pleasure working with you."

"The office staff was very good at scheduling and the estimation, prompt, efficient and great to deal with. The staff who had to come to do some prep work and the staff who did the insulating were on time and worked well until the job was completed. The price was also less than two other estimates. Over all, on every aspect of the job, we would give Mincin 5 STARS. Thank You."

"The job was extremely difficult due to three different layers of insulation in my attic including blown in insulation. They suggested I go with the foam. I requested they not spend to much time cleaning up because I wanted to clean the entire garage."

Insulation FAQs, answered by experts

Yes, energy-efficient homes are increasingly desirable in the market.

If you’re moving wires, installing new wires, or installing new fixtures in the space you’re insulating, then you will need to hire a licensed electrician to do that portion of the job for you. However, if you just intend on replacing old insulation or adding new insulation over existing insulation, then you don’t need to hire one. Your insulation installer will work around wiring, fixtures, outlets, and switches, even if they’re installing fiberglass batts in the voids where wires run. However, you will need an electrician if you suspect a problem with your wiring during the insulation work.

Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks. Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line.

It improves energy efficiency, reduces noise, enhances indoor comfort, and prevents drafts by filling wall cavities.
