The average price to Insulate an Attic with Blow-in Insulation noted above is cost data to compare a contractor’s estimate with doing it yourself.
How much is blow-in insulation? An insulation contractor charges $1,386 to install blow-in insulation compared doing it yourself for $875 and saving 36 percent.
Today’s high cost of energy is leading many homeowners to take a new interest in their attic insulation. Adding blow-in insulation is an easy do-it-yourself project that can prevent your attic from acting like a sieve for your heating and cooling dollars.
The job requires common sense skills and a blower tool you can borrow from the retailer where you buy the insulation. If you want to hire someone for the work, you’ll find insulation contractors listed online by using a search engine to find an online contractor referral website. No matter who does it, buttoning up the attic with additional insulation is a job worth doing.
An insulation contractor will charge $1,386 to blow insulation into an 1200-square foot open attic area with 12-inch deep coverage. This includes the labor and material. A handy homeowner who is agile and can easily climb around the unfinished area of an attic can do the job for $875, the cost to insulate the attic with insulation, and pocket a nice 36 percent saving.
Before you choose a retailer to buy the bags of insulation, make sure they offer a blowing machine to their customers. Most of them require a deposit, which is returned when you return the machine. You will also need a good respirator and old clothes to protect you from the insulation dust.
Weather-wise plan this project for the spring or fall when attic temperatures are temperate. Don’t schedule the job in the summer months, when it’s too hot to work in a hot confined area.
The Types of Insulation are explained here by Energy.gov.
The bottom line: compare the price of a contractor’s bid to blow in attic insulation with what it costs to do it yourself and make your decision.
