Insulating a cathedral ceiling
House was built in the late 1800s.
We got the house last year, and we noticed it was immediately freezing cold in the house upstairs, and the upstairs furnace would run all the time. Our heating bills were around $600 a month. The second the furnace would turn off you'd feel a creeping cold in the air, and within a minute or two the furnace would be back on. This year, its a bit different. While last year we just accepted it and bundled up, this year we're on a single income, with 2 very small babies in the house. They had their share of health scares when they were born, and I really don't want to put them in any risk.
I drilled holes in the ceiling drywall in a couple places, and stuck a mirror and flashlight in - there is nothing in there at all. When the sellers renovated from an attic to a cathedral ceiling, they just cut corners and put nothing in there at all. Luckily, it does look like the walls are insulated.
