I recently purchased a Queen Anne style home built approximately in 1902-3. I have two categories of question: 1) The basement walls, the foundation, are brick with a mortar that is continually crumbling away and falling to the floor. It is yellow in color and the texture is a fine powder. Two questions: does this situation pose a threat to the stability of my house? If so, how do I repair it? 2) Around the outside perimeter of my house is a "facia" brick. It appears to be a decorative foundation, not the red brick in the basement. This one is very small rectangles with a tuck point/butterjoint mortar. The mortar has and is eroding and the bricks are loose in many spots. I assume this is contributing to water leakage in the basement as well as insulation challenges. Is there a way to fix this situation other than hiring (at a cost prohibitive rate) someone to do tuck point?
