A free workshop, "Water Water Everywhere," will be presented from 9:30 a.m. to noon Saturday, Oct. 20 to help historic building owners understand how to diagnose and control unwanted moisture.

The workshop will be at the Jefferson County Public Library Madison branch.

Uncontrolled moisture is the most prevalent cause of deterioration in older and historic buildings. Topics will include: How and where to look for damaging moisture; above-grade and below-grade moisture entering the building; leaking plumbing pipes and mechanical equipment; interior moisture; as well as methods of treatment.

Camille Fife, preservation planner for the City of Madison, will conduct the workshop. Jack Patchin of Ole House Experts in Madison will be the chief presenter. Patchin has experience working with many aspects of historic preservation. He has presented a workshop on moisture in historic buildings for Frederick, Md. A case study of a situation in a Madison home will also be presented, showing some of the things that were attempted and how the problem was solved.

The workshop is co-sponsored by the City of Madison's Office of Historic Preservation in collaboration with the Madison Main Street Program and the Cornerstone Society Inc. The public is invited to attend and refreshments will be served. There is no charge for the workshop, but donations will be accepted.
