I'm winterizing my upstate NY summer house (bungalow style little house) that's at least 50, maybe 80 years old. The back half of the house is over a crawl space, i.e. no basement and no subterranean foundation. I'm looking to have insulation blown into the walls though I'm not sure if it's needed in the floor - that's what I'm hoping you fellas can help me determine. My issue is keeping the plumbing underneath the house warm enough.
1. I know I need to block off the crawl space to prevent freezing wind blasts to the pipes but what do you feel is sufficient to secure that space to keep the pipes from freezing? Is a concrete footing with plywood backed with some insulation board enough or are there better solutions?
2. What's the best way to keep the pipes insulated/heated? I have asked a local plumber, Home Depot, and the blown-insulation guy and I get conflicting assessments. I have been told heat tape (assuming now power outages) will be fine, but others say no way, it won't be enough.
I sincerely appreaciate your help and guidance here. I have to do most if not all of this work myself and can't afford to just turn the job over to the pros
