[Reno RSS Feed]

I have a building made from bessa block and is rendered. the bottom of the door frames on a couple of doors are rusted out and in need of replacing. How do i go about replacing the rusted section?? how do i hold the new section in?? do i weld it to the remaining section after i cut out the rusted area and grind back the weld or what??
