The lower level bricks in my firebox are cracking. The top level is ok and I had the rest of the furnace inspected for cracks. I use 80 percent oil and twenty percent wood. I haven't really explored how I would get them out, but ordering replacements from the furnace company would be hundreds because of the extreme shipping weight. Money's tight and I came across this product. What do you think?
You're looking at ashes at the base, not crumbling masonry.
