We’ve discussed here how inspection of any brick work should be inspected and followed up by brick repair. As a homeowner, you’ll most likely hire a masonry contractor to do the work, a wise decision, but you may still wonder how brick repair is done.
After the masonry contractor has determined the cause of any problem noted, and that problem has been addressed, here are the step they will follow to repair the brick:
Clean the Existing: The additives, clays, coatings, and shales, need to be cleaned first. The masonry contractor will determine the best cleaning product and process to use based on the manufacturer of the brick.
There are proprietary formulated products that may be used for any stubborn, tough stains. The also use pressure washers, but careful as to what chemicals they use and how high of a pressure. The wrong combination can cause more damage.
Repairing and Repointing: Repairing brick work is called repointing. This is where the masonry contractor removes any mortar that is damaged or deteriorated, creating a uniform depth before replacing new mortar. They do the best they can to replicate the original mortar or get as close as possible with a slightly less compressive strength.
Seal the Replacement: Where the brickwork meets other surfaces, such as doors, roofs, windows, is referred to as an intersection. A sealant is used to fill these areas where mortar isn’t used. The sealant will have a five to twenty-year lifespan.
Removing Vegetation: While it may look cozy, and inviting for a home’s brick work façade to be covered in ivy, it can cause damage to the structure over time. The ivy penetrates into any void in the mortar which allows water infiltration. Pulling the vines is not the recommended way to remove them. A masonry contractor will cut them close to the brick, but leave a bit hanging out so that they can go back later and pull them out after they have dried with a stiff brush.
