Dense Pack Cellulose in 50yo house

[Astro]

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,

I was googling insulation and there are a few new ways for fiberglass and cellulose to be instaled with a glue binder so it does not settle, there are different R values as well. So some ways insulate much better. Do a Google, use the phone book ,get prices, facts and refrences, even foams are back. Some new processes may not be avalaible in your area, so look around.

Hi, I don't mean to sound snarky. I spent about 5 hours Googling and the information I saw indicated that dense-pack cellulose absolutely doesn't settle since as it's already "densely packed". Lots of benefits are listed

- almost zero air infiltration, sealing of air leaks, little/no insulative capacity change over time, bug/mouse resistance. I found nothing about any variations on the dense-pack cellulose installations. Can you give some specific links?

I plan on getting a few bids. Definitely a good idea.

The question is, what type of price should I expect? I know nobody likes answering pricing questions and the stock answer is invariably "talk to the local contractor", which I plan to.

I understand pricing varies depending on the difficulty of the job, geographical norms, etc. But there's got to be a "reasonable" price for this type of job. And since I plan on doing several properties, it would be nice to have a baseline cost.

Anybody in Eastern PA, NJ or thereabouts who have had dense pack cellulose installed in their walls? Can anybody recommend a contractor around here (Bucks County, PA) who does it? The yellow pages for Doylestown only shows people who do polyurethane.

thanks
