A further question to ask is should I insulate a home built the 1920s? There are different schools of thought to this question, so let us explore the reasoning behind why you will hear different contractors make various suggestions.

A popular retrofit for older homes is new windows, but you may not be installing them correctly. Proper flashing is one concern.

Controlling the amount of moisture in your home is achieved through vents in the bathrooms, utility room, and kitchen, as well as opening windows. The ducts for the mechanical vents are often not in the best of shape during home inspections, since they are easy to forget.

If you have a window or door that sits flush or proud of the wall, you probably then have trim sitting on the wall. This can be a problem area for moisture.

Can you fully close your windows? Does it matter if you cannot? When looking at homes small things can make a big difference.

When you begin to seal and insulate your home, moisture can become a bigger problem. A constant supply of moisture can lead to mold, but non-constant moisture can lead to problems with wall coverings and more.
