Suggestions for retrofitting a 1908 house with insulation?

Asked by Juniper

Original construction with lathe and plaster walls and redwood siding. Blow in pros and cons? Also, the ground floor sits on a foundation which is a crawl space so the floors are pretty cold...any suggestions for insulating the crawl space?

We have been very successful with conditioning the crawlspace. This process seals off the crawlspace and conditions the air to be closer to the air temperature inside the house.

For the walls, I'd recommend cellulose insulation applied in a drill and fill manner either on the outside of the house or the inside.

There are great monetary incentives for this type of work, not to mention the increased comfort and energy savings achieved.
