People choose brick and stone for the exterior of their homes for durability, aesthetic and longevity. While properelly constructed masonry systems will typically last decades, some maintenance may be required to keep it looking good as new and structurally sound. When your mortar joints appear to be cracking or eroding, it is critical that you call in a licensed professional restoration mason to repoint your brick or stone in order to prevent costly repairs down the road.
What is Repointing?
Repointing is the act of replacing deteriorated or cracked mortar in masonry. It involves the raking out, refilling and finishing of joints with new mortar. Old mortar is cut or grinded out with specialized masonry tools to a minimum depth of 25 millimetres. The joints are cleaned out and then repacked with the right prescribed mortar and colour match depending on the brick or stone.
Prevents Structural Failure
Masonry structures that have deteriorated mortar joints allow for water and moisture to readily penetrate the wall. With the frequent freeze thaw cycles we get here in Ottawa, it can cause pressure to build leading to damaged units and if left unaddressed long enough, potential collapse. Repointing your wall will revitalize the structural integrity of the masonry work by sealing up the joints from weathering.
Avoid Water Penetration
As explained previously, open mortar joints are susceptible to accelerated water penetration. Moisture that is absorbed through the mortar joints can further penetrate into the timber behind your masonry if not properly moisture barriered and can create a dampness in your home.
Revitalize your Home's Beauty
A properly done repointing of your home's exterior can really rejuvenate its appearance. Mortar that has degraded can be an eye sore that make your brick or stone look run-down. Fresh mortar that is tooled right can help add-value to your home as the exterior looks well taken care of.
Save Money
Eroded mortar joints can lead to water penetration that can cause major structral issues or damage to the bricks or stones themselves. Repointing is an inexpensive maintenance option that prevents the chance for more costly repairs down the road like a complete re-build or brick replacement project.
Choose a Qualified Professional
Having the exterior of your home repointed should always be carried out by a Mason that specializes in restoration work like Kavanagh Masonry. This will ensure that the best mortar recipe is used, the right colour match is done, and the joints are tooled to look exactly like the rest of your home and blend in nicely.
