I am living in an rowhouse with exterior walls built of 2x4's. When it gets really cold in the winter - I can feel the cold coming through the wall of my bedroom when I put my hand on it. The wall is about 12' wide by 8' tall with 2 windows. Is there something I can do to better insulate? The only thing I can think of is to remove the drywall and furr out the wall and re-insulate. Are there any less destructive and DIY options?
You can have blown-in insulation added after the fact. They will drill small, maybe 1-1/2" holes in the stucco, one above and one below the fire blocks in each section between the studs and blow in the chopped fiberglass material. then they patch the stucco and if you have some of the original leftover paint, they will repaint it. If not they try to match it, but the success of that varies.
Most HOAs will allow this by the way, so long as the contractor is licensed and in some cases pre-approved by the HOA.
