It’s an age-old question we, as contractors, face when deciding whether to stay specialized on the trade(s) we currently do or if it makes sense to add another trade to the existing mix.
Coming from a family business that originally only did heating, I can tell you the pros and the cons for us. The pro, we worked like crazy during the busy season and then could enjoy our time off in the slow season. The con is we opened ourselves up to other contractors who would lock us out of our customers’ basement because they could serve the customer as a one-stop shopping experience.
