We recently purchased a 1910 home and there is no insulation in the walls, what is the best way to insulate this home without removing sheetrock or plaster? We do have to repaint the entire outside in the spring can we insulate from the outside? It is a wood sided home.

    Hi Todd, depending on the construction of your home it is possible to put a hole in the top of the wall between each of your studs and blow in insulation, it would require patching those holes (whether on the inside or the outside) but you could probably find a company who could do it.

    Hiring a foam insulation contractor is the best.

    If you decide that you don't need the best, your house is from the era where they used balloon framing. It is possible that your walls are open in the basement and in the attic. If you plug up the bottom you could use a pour-in insulation from the attic in each cavity between the studs. You won't be able to fill all of the cavities, like under windows or where there is blocking in the stud bay, but it will be better than what you have and cheaper than foam.

    Foam insulation can be blown in through holes they drill in the wall, then patched. This shows you how. Here is a link to just show you there are places out there, not to endorse a company. I hope this helps.

    Older homes often have lathe and plaster walls and do not have hollow cores to fill with insulation. Since most heat is lost to the ceilings, your first insulation should be in the attic. Then you will decide if an external foam board under new siding is in order.This will help a lot.

    Yes, you can insulate from outside. I did. Had the house Tyvek wrapped. shaped foam panels to suit the siding that was installed. Easy.. make sure that near the fireplace chimney that fire proof insulation is used. If you install new modern insulated windows are to be installed. Do the Windows first to insure that the whole house is insulated and vented properly.

    My daughter has an old farmhouse built in the 1930's. Plaster and lathe inside. Wood siding outside. She had blown in insulation put in the walls. They drilled holes about one foot below the roof line and holes about one foot above the foundation. Blew in the insulation from the top until it flowed out the bottom. Plugged the holes with wood plugs when finished.
