I have brick house built in 1951 with plaster walls....couple of years ago I
blew in cellulose insulation....the hardest part was finding all the
studs...overall the whole process was quite simple...I used hole saw - 1 1/4
inch - cut holes few inches down from ceiling and under windows...once we
got the machine, was real quick and easy to blow insulation into
cavaties...the whole house took maybe an hour to complete....to fix holes I
made small depression in insulation with finger then filled with expanding
foam, next day sliced off excess foam a little below wall surface, then
filled with all purpose joint compound, sanded and painted.

Check at cellar level. For fire breaks. You might put
twenty bags of fluff into one cavity, and find out later
that you're pumping fluff into your cellar. Don't laugh.

A 50+ year old house may have balloon framing.
(Essentially an
obstruction free space between the studs, top to bottom).
You could
get a blower and bags of insulation and blow them into the
wall from
the attic. Instead of supplying the cash you supply the
labor.

depends on the size of the space. my guy charges 75 cents a square foot
to drill and fill a 3 1/2" wall space. Same deal, plugged, but not
painted. They drill most of them around here on the outside if it's
just wood siding. He even does it under vinyl just lifts the siding,
then drills and plugs.

I'm sure the insulation will help, just how effective it will be
nobody knows. Typically, a ceiling transfers more heat than walls.
You might be able to know more by taping several thermometers to the
walls/ceilings or use an IR detector. You may get a better price if
you can get a few more (local) estimates, but experience/reputation is
important too.
