Finishing a finished basement
We purchased a brick veneered ranch home in the St Louis area about a year ago. The home is about 44 years old. The brick is in very good condition, but doesn’t have weep holes at the bottom. In several areas that I can check there is an air gap between the brick and sheathing of the 2 x 4 framed wall of the house. This gap appears to be 3/4 to 1 inch. Currently the basement is finished except for 2 utility rooms. The finished areas have 1/2 inch drywall over 1 x 3 or 2 x 2 furring strips attached to the foundation wall. After reading, All about basement insulation, How to insulate a basement, Retrofitting basement insulation and other articles it leaves me with several questions.
1. Is the insulation approach the same for a brick veneer house as a frame?
Foam in rim joist, foam to foundation, 2 x 4 wall…
2. And in my case the bigger question is does this justify the cost, time and effort of gutting a previously finished basement to add proper insulation and refinish?
