I'm removing a fireplace. The lintel is higher than I want the finished opening. My plan is to add a lintel (http://www.wickes.co.uk/Wickes-Steel-Reinforced-Concrete-Lintels/p/9000038435) lower down to support the bricks below th main lintel.

I now see a couple of hairline cracks in the existing lintel. Is this a concern? Should I get a professional in to have a look? House built 1948.
