Many times it is found that there is little or no insulation behind the walls of old houses. This can come as a surprise to most buyers because they just don't know. Usually, around my territory of Long Island, I have found houses that I thought would be insulated are not, and houses that normally wouldn't be insulated are insulated.

Many of the old plaster and wood lath homes are without insulation within the walls, but back when they were built, the cost of heating a home was not much of your budget. These hollow walls can have blown-in insulation added. It is unusual to find a home that is made with standard drywall without insulation, but sometimes you find the walls are hollow.

This was the case in Elmont, Long Island two days ago. The buyer was getting a tremendous deal on a foreclosure. The cost to insulate will be saved many times over once he buys the house and repairs what is needed. - Ray
