I live in a 1944 colonial that has steel grained siding. It is an old siding .a few years ago my wife, who has lived there for many years, had the house for sale. The realator told her he would get it painted to enhance the house. He hired someone and it was done in a white paint. A few years after it started peeling and looked horrible. We contracted with a professional painter who did sc**** and power wash the whole house before he painted it.He did allow the wash water to dry . Using Sherman Williams exterior house paint it looked good until about a year afterwards. Big pices of the paint peeled off, this past winter I noticed bubbling of area with moistire in some of the ones I broke open. I am at the end of my knowledge and wonder what I can do . There are spots with small areas of peeling and a few major pieces, the paint will lift off it you get a finger nail under a peeling area. Where do I start. The house is 2 stories and I am handicapped ,unable to climb a ladder. How can I detrermine what the real problem is?
