PORTLAND — Greater Portland Landmarks is hosting the 2015 Old House Trade Show on Saturday and Sunday, March 28 and 29, at the Holiday Inn by the Bay, 88 Spring St., in Portland.

The Old House Trade Show is the only one of its kind in Maine. The two-day show features approximately 50 exhibitors who represent trades, services and products related to restoration and preservation of older homes and buildings. The program will feature workshops, roundtables and “ask the expert” segments that are designed to educate the public and match homeowners with professionals who can best serve them. The show will feature energy efficiency themes.

Because of the number of older and historic homes and buildings in greater Portland and throughout Maine, the show presents an opportunity for property owners to learn from and about businesses, craftspeople and service providers who can help them with advice and services that are vital to preserving and renewing their historic houses and properties.

The Old House Trade Show Program and Directory will be available for all show attendees and distributed to members of the public at www.portlandlandmarks.org and more than 50 locations throughout greater Portland in advance of the show.

The Old House Trade Show’s lead sponsors include Norway Savings Bank, Benchmark Residential & Investment Real Estate, Cornerstone Building & Restoration, Heritage Company Coppersmiths LLC, Marvin Design Gallery by Eldredge, Taggart Construction, Innerglass Window Systems LLC, Your Kitchen Imagined and Home Again by Hancock Lumber.

The Trade Show will run from 10 a.m. to 5 p.m. on Saturday, March 28, and from 10 a.m. to 4 p.m. on Sunday, March 29.
