Hello Eichler Neighbors,
I've lived in my Eichler for 12 years and for 12 years, my living area has been freezing for 12 years.
To make a long story short, I had my chimney "capped." I left for two hours and came back to a toasty home! I kept thinking it was my 1954 single pane plate glass windows causing the coldness. Nope, it was the chimney! The need to replace the windows went down a few notches.
This cap doesn't seal it to prevent from burning wood. What it is a unit that sits on top of the chimney. A cable is dropped and is attached to inside the hearth. When I want to to open the chimney, I release this spring-loaded plate and I can light a fire.
In these cold weather, it is a pleasure to come home to a warm home.
