Let me tell you about the beadboard ceilings: we "preserved" the original ceilings in the parlor and dining room to help keep the historic feel in the front of the house. I would have loved to have preserved the beadboard ceiling throughout the entire house except that it was ALL in terrible shape... there were layers and layers of drywall, random pieces missing, etc. The plan was for me to tackle the two ceilings perhaps during the major reno (before we moved in) but that didn't happen, and I certainly haven't gotten to it since.
Here are some before pictures. They are very disorienting but at least I documented it before the work started. :)
We hired painters directly for this; specifically Graduate Custom Painting and they have been phenomenal. They are extremely thorough and the quality of work/level of detail is truly exceptional. They started Wednesday of this week and will be done Saturday afternoon. The ceilings tested positive for lead paint so they are using the highest level of caution for this job and have completely sealed off that part of the house in addition to taping off all the walls, etc. In this situation, we can't really remove the lead paint, so they are using a special primer to ensure the best encapsulation. It's taking a lot of work to remove the thousands of extra nails left behind, not to mention filling in drywall screw holes... I never could have done what they have done!
So it's not done yet but here are a few "during" pictures. They will do more caulking and another coat of primer before the actual ceiling paint goes on.
