Flagstone sun porch
I bought a home a couple of years ago with a flagstone porch. The windows are screen with storm windows but no insulation so it is a 3 season room. Well the flagstone floor is peeling and coming up in a couple of places. It doesn't look like there is a sub floor so we are wondering what to do...Re-seal or pull up the floor... The wall (up to the windows) is stone going around on 3 sides and the top slat over the stone wall is peeling. There are some spots where you can see salt corrosion but I don't know if that is a problem. Any suggestions would be wonderful!
Ps. we live in CT if that matters
