Insulation

Ever thought about doing a better job of insulating the outside of your house? There are a lot of options available. The most expensive is to rip down your drywall and put up new with better insulation inside. The next step down is to laminate more drywall over your existing drywall. Going down still further in price is having holes drilled in your block (from the outside) and foam insulation injected (then the holes get patched). But I just found out about loose fill insulation and other similar products which can be blown in to existing walls by cutting small openings in the walls at every stud (usually every 16 or 24 inches). You cut the holes, blow the insulation in using special equipment, and patch the wall back to look good as new. This can be hard when walls are wallpapered because you can't really patch wallpaper. You don't get as much r-value as installing board insulation in new walls, but you save a fortune. Estimates I found online showed an average of 50 cents per square foot for the complete process including patching your wall back to normal, but those could have been old or inacurate estimates, so I recommend you contact several companies in your area and compare their quotes.
