I am writing with a question about arched laminated beams that are a main structural element in my 27-year-old home. There are three beams in total, about 80 feet in length. A few feet from the end of one there is some delamination in the top 30 inches of a 15-by-4-inch beam, along with something like a fungus in some places. How should I repair this, or whom would you recommend to assess the needed repairs?
