Check your local utility company for programs. With rebates, it could be
cheaper to higher one of their certified installers to blow in fiberglass.
In Mass., there's a 50 percent rebate up to $3,000 through NSTAR.

I have about R-19 insulation in attic. I want to add R-30 more. R-30
batts in HomeDepot have paper vaopr barrier. Should I remove it before
adding R-30 batts over existing batss to prevent double barrier or I
can put them as is?
