Retrofit insulation?

[bolson]

Dear Dr Lj,
My old house is cold and heated by expensive oil, I believe the best course of action is to improve its insulation. Blowing in insulating fluff into the attic seems like it should be an easy win. I hear this can be done to the walls too, but is somewhat more involved as it may include peeling off parts of the siding and cutting holes to blow in through. I just had another thought, take off all the siding and add a few inches of insulative thickness to all the outer walls. This of course seems like a somewhat radical measure. Any ideas on if this is otherwise a reasonable idea? Anyone else heard of this or other thins being done?

blowing into the walls shouldn't be a big deal even with the hole drilling, they'd lift the outer layer of siding, drill underneath, and then bung/re-lay the siding so you'd never know. Doing it yourself would be cheaper, but probably require scaffold to do it right :-D.

the attic thing you could do yourself although it's a bit messy :-)
