Tri County Barns is an authorized dealer of MD Barnmaster buildings, which are constructed of excellent quality materials; however, they are at the high end of the price range. I had Tri County construct a separate barn/garage for me when I built my house, and was satisfied with the building and the work done by the construction crew. Recently, I wanted to purchase the materials for a pasture shelter and construct the building myself, and contacted Tri County again. This was not a satisfying experience for a few reasons: — they were difficult to reach by phone and didn’t respond for days to emails, — the price was the most expensive of all options I was considering, — after paying for the building, they tried to charge me an additional $ 1000 for an error in their shipping estimate, — the building they sent did not match the building I requested, even though the building I requested is featured on their website and I sent them the photo of it in my request, — they provided no schematics or instructions on how to construct the building, — after multiple requests, they supplied a parts list and a sketch showing the overall size of the building(not helpful), then stopped responding altogether to further questions about how to construct the building. Bottom line: After some internet research, we did get the building up and I am satisfied with the materials quality. However, if you are a DIY’er, I do not recommend Tri County/MD Barnmaster. Find a supplier who provides support for you and has good customer service.
