Masonry Firebox Repairs |
||||||||||
| Why is it necessary? | ||||||||||
| Cracks and gaps in firebox bricks and mortar are a potential fire hazard. In most masonry fireplaces the areas behind the firebox sidewalls are typically hollow, and since a fire will produce a minimum of 500 degrees of heat, it will cause these cracks and gaps to expand and can transfer the heat and gases to areas behind the walls where there may be direct exposure to combustible building materials such as wooden walls studs or drywall. | ||||||||||
| The solution | ||||||||||
| In most cases, it is possible to widen the cracks and patch with a high temperature mortar patching material. If the backwall in the firebox requires more extensive patching, we also recommend to install a stainless steel Heat Shield for added protection since it will reduce and spread the heat going to that area. In more extreme cases where the damage is beyond just patching, we will refer you to an experienced chimney mason for a more extensive repair. | ||||||||||
| Please note | ||||||||||
| Patching a firebox crack is not the same as rebuilding the firebox. While we do our best to make as clean a repair as possible, you will see where it has been patched. Also, over time it is likely that the area will need to be patched again, especially if the patching was extensive. Our experience has been that the Heat Shield goes a long way in protecting the patching. | ||||||||||
