I am in the process of having cellulose insulation blown into empty
wall cavities. The contractor is almost finished and is supposed to
complete the job Monday.

In looking over the work done so far, I have some concerns. the
insulation is being blown in from the outside. Holes are being drilled
in 2 points in each cavity which from what I know is the correct way.
One hole is about 1 foot from the bottom of the wall and the other is
about threee feet from the top. It seems that this wouldn't completely
fill the wall with holes drilled so low. Just to be sure I checked 1
cavity and found about a 5" gap with no insulation at the top of the
cavity.

There are also spots which have not been drilled and filled above
windows in parts of the house that are considered complete.

Is it reasonable to expect wall cavities to be completely filled or am
I nitpicking? I am thinking I should address this with the contractor,
before I pay for the job.

Any thoughts. Thanks.

jimbob,

As I am in the process of remodeling my second room from total teardown
and well on my way to journeyman carpenter in the process.. LOL The
header over the windows and doors that distributes the load of the wall
is a fairly solid piece of wood blocking that is the thickness of the
wall and is 8-10 inches tall minimum, but can be the total height of
the difference to the top of the wall depending on local codes, union
trade practices, and even if there is a second floor or not . so its
usually not possible to insulate it at all.

Hope this helps, Jimbo

On the two houses I've seen this done to, one hole was drilled near
the top for each cavity.

I called the contractor today and explained things. He said there were
likely headers above the windows as jim said. I do believe this
explanation. They are 4 foot thermalpane windows.

I asked his if he would drill another row of holes closer to the top of
cavities to make sure they were topped up. He said he would and this
would be fine with me. I was polite but firm. Hopefully it will work
out alright.

Thanks for your replies.
