I just bought a home built in 1987 with 20” hemlock logs. It has never been stained, and is very dark gray. My insurance company required new porch railings. My contractor made railings out of white pine, but they are very light. He wants to bleach the rest of the home, then put some sort of clear coating on it. Is this the right move? The house has 24′ tall ceilings, and would cost a fortune to corn cob. Would the pine darken to match the hemlock if left alone?
