I wonder if anyone here knows how to solve this problem. My husband and I bought a 109 year old Folk Victorian three years ago. (It's 109 now--107 when we bought it.)
One thing the inspector did not check, and we did not think to question, was insulation under the main floor. There is none. Ordinarily, it would be simple to remedy, but our crawlspace is very shallow. Toward the back of the house, there is room to scoot along on your back with room to reach the joists freely. The closer you get to the front, it becomes impossible.
Short of taking a shovel and digging out a trench as we go to access it, are there any other options for insulating the main floor? We even considered laying rigid foam over the existing floor and then installing a whole new floor over it! (A person gets pretty desperate when its 19 degrees outside.)
