Repaired 7 holes in our ceiling after insulation was blown in. Repairs were done poorly and when I called Abraham to come back to look at repairs and fix, he ghosted me. Damaged walls with paint spills and hand prints as well.

We couldn’t get our termite bond renewed until the hanging insulation was removed. He came when he said he would and cleaned up our crawl space and left everything neat and clean and took away the many bags of insulation. Our bond was renewed after another inspection.

Insulation questions, answered by experts

Cellulose insulation is usually made from recycled paper products, such as old newspapers, but cellulose might also contain recycled denim. While most homeowners traditionally buy cellulose insulation to use for installation, it is possible to make your own at home with old newspapers, cardboard, a paper shredder, and boric acid (important for fireproofing your cellulose insulation materials).

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install blown-in insulation. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than $100. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.

Regular inspections for moisture damage, pest infestations, and proper R-value performance help maintain efficiency.

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses.
