Old field stone foundation
I have an 1850s brick house that I recently moved into. I live in a very cold part of NY and I am trying to reduce my energy consumption.
My basement is damp, not overly wet, but by no means dry. 3/4 of the basement has a poured slab, the remainder is dirt floor(covered by plastic).
My plumbing, furnace, hotwater heater are all in the basement, but it is by no means a finished (nor will it be)
Realistically I would love to just spray closed cell foam around the rimjoist and fill in any obvious gaps around the top of the foundation walls, but the cost to do that is approx 450$, which is not bad, but there is a 1000$ minimum for the sprayfoam company to come out.
The spray-foam company suggested/quoted me to do the basement ceiling to minimize the amount of cold air being sucked out of the basement.
Would sprayfoaming the entire field-stone wall be a better choice(or even just a few feet down)?
Are there any negatives to insulating the basement ceiling if it will not be a finished space? I love the idea of keeping the cold/moisture in the basement where my dehumidifier can take care of it.
Thanks in advance for any suggestions.
