Is a Brick and Mortar Repair Needed?
Some minor imperfections in your brickwork may not require repair at all, such as fine hairline cracks or minor erosion of mortar. However, delaying other repairs could allow damage to other components of your home. For example, broken brick and cracked mortar joints wider than 1/16” (Can you insert a dime in the crack?) not only look bad, but can also allow water penetration with resulting damage to other construction materials behind the wall. Excel Chimney can help you prioritize any necessary brick repair issues and give you a free written estimate for restoring your home’s brickwork to its original (or even improved) beauty and function.
The technique for repairing mortar properly, or “repointing,” is similar to a dentist’s repair on a tooth’s cavity—the doctor doesn’t simply fill the cavity in a one-step procedure. Voids and deteriorated or cracked mortar joints must first be ground or chiseled out to a minimum depth of 5/8” and the cavity cleaned out thoroughly. For repairs, mortar should be pre-shrunk, and the cavity moistened before placing the new mortar. These steps take additional time but help to insure proper bonding of the original mortar to the new mortar, and helps prevent shrinking as it dries. Mortar should be custom-blended to match existing, without using unauthorized additives such as latex. Any additive should first be approved by a proper governing authority to insure that it meets industry standards for strength and durability.
