Commercial Door Weatherstripping

I have recetntly purchased a commercial property and one of my storefronts has a pair of double doors that have a 1/4 inch gap between the two doors even though one of hte doors has a new brush weatherstripping installed.  Both doors open independantly and the 2nd door has a smooth edge.  The brushes on the weather stripping do not touch the 2nd door.  Do you sell something to make the 2nd door a bit bigger or is there another option I should be considering?
