Would appreciate thoughts- my plan of attack in order: remove 40″ window, lay our r.o. for 5′ door, cut out plaster, install new studs and 2×6 hdr (not a bearing wall), locate outside edge of studs on brick and cut brick with brick saw at anticipated outside edge of brick mold, install new lintel.
Re: lintel- I assume a 6′ lintel would be about right? Masonry suppliers have not been consistent recommending size of angle I need. My guess is 3 1/2″ x 3 1/2″x 5/16″ would be OK? What problems should I anticipate getting old lintel out? Are they bolted to studs? What tips for getting new one in with minimal trashing of exisiting brick work?
