You should try calling an insulation contractor, you will be amazed at
how affordable it is. Very VERY close to what you would pay for just the
insulation itself. Example, I just added a 2nd floor on my home, I did it
mostly myself with the exception of the insulation and the plastering. I
knew exactly how much of each size I needed, priced it at home depot and
knew what it was going to cost. One of my family members suggested I get a
price from someone to do it, that they had just done it at their home. I
called 2 different local insulation contractors, both were within 100$ of
eachother. My cost just for the insulation and the rigid air baffles/dams
for the rafter space was roughly 2000$ at das' depot, their total price for
the same with installation was 2200$. What would have taken me probably 2
weekends to do, they did in a day, they sent 3 guys out, one guys was
cutting everything and the other two were hanging it. It was exactly as my
plans specified and the work was flawless. Best 200$ I ever spent. They
either get a very decent discount from their suppliers on the insulation or
they pay their guys pennies.
Periodically HD and Lowes have sales (check your ads).
Both (in this area) provide a free but heavy blower for the Cellulose
insulation (made from at least 75 percent recycled material and
requires 2 people to lift the device.)
Installation is a 2 person job even if your doing roll fiberglass.
Neither provide free delivery even with large purchases. (in my case 60
bales of insulation requires a truck.) Storage becomes an issue if you
can't install it on the day of delivery.
Better hurry if your making a blower type insulation - neither would
guarantee a unit on a specific date (true as the temperature gets
colder and people see their heating bills.)
I talked with a couple of insulation installers at a recent home show
who "verbally quoted" me prices of $1.50 - .75 square foot for blown
insulation. Everything was "subject" to adjustment before a formal
quote could be made. And while they kept emphasizing that people in
"our region" needs R48 levels that was not the level they were quoting
for the $1.50-.75 installation..... sigh. Make sure you GET what you
pay for if you go that route. (Quote needs to include the number of
batts or bags to be installed.) Get references!!!!
A more realistic R factor is probably R25-R30 over existing
It does cost more to do fiberglass than the Celleulose attic insulation
but you can install it at your leisure versus getting a blower.
