Preston Hardware is the place I go to to find everything I can't find in other stores. In fact, employees of other hardware stores often refer me to Preston Hardware when they can't help me. It is the mecca of obscure renovation supplies, that certain bit of plumbing or the tool unobtainable elsewhere. The staff are super knowledgeable; I once took the plumbing staff this odd lumpy bit of plumbing from under my sink which looked like the previous owner had somehow exploded the metal drain pipes, and they figured out what I would need to replace the now unidentifiable part, and made sure I had absolutely everything I required for the job. If you are a home repair neophyte, I recommend them hands down, and if you're an expert, you surely are already familiar with them. I find they are a bit pricier than other home renovation stores, but the range of items and knowledge of the staff will save you time and money in the end.
