I'm looking to get my currently uninsulated walls filled with dense-pack cellulose. From everything I read, it looks like the way to go for this type of retrofit.
My house is about 50yo, plaster inside walls. Overall, construction is pretty tight. Located in eastern PA.
two questions:
1) any reason why I should NOT use cellulose for filling the walls of this era house? I hear that pressures are high enough that people have had walls damaged by the process.2) what's typical cost (per sq. ft?) for dense-pack? I understand that there are lots of variables, but it would be nice to know if I'm getting a highball price. Contractors in my area tend to try to squeeze every last penny out of you because it's a high rent district. It's not unusual to get quotes 50% higher for nearly identical work just 15 miles south of here.
Thanks,
