Hi I am new to this forum and appreciate any advice.
I recently bought a 50-year-old house in MD. The attic has about 8 inches of cellulose insulation, which is still fluffy and in light grey color. I am wondering if the insulation is still good after 50 years and if I should replace them before moving in. Any suggestion?
If they need be replaced, anyone knows where I can rent some equipments to remove the old and add new insulation? How much would it cost? After reading a lot of reviews and comparisons, I plan to stick on cellulose.
Also for insulation in the wall. The house is built with bricks, and I heard there is not much insulation in the wall. I am also planning to blow in some insulation. To do this, should I open a small hole in the drywall between every pair of studs to add insulation, or is there a good way to do it?
Any comment and suggestion is appreciated.
