The concrete brick walkway and stairs in front of house are crumbling badly. One contractor wants to overlay with brick veneer ($7500 +) These bricks were laid over an existing concrete walkway some 30 years ago.. Is overlaying a good solution, or can I do something better (and maybe cheaper)? We will have a safety hazard soon, so I need to do something. I am fairly handy, patient, and learn quickly. Husband not so. I have thought of maybe chiseling out the old brick and relaying something else, but if I start and it proves too much for me...then what?
