The construction term “pointing” refers to the finishing of mortar joints in masonry, be it stone or brick. Mortar often does not have as long a lifespan as the brick it holds together, and over the years must be periodically removed and replaced. Repointing is the process of removing deteriorated mortar from the joints of a masonry wall and replacing it with new mortar. Repointing restores the visual and physical integrity of the masonry, and therefore the longevity of the building envelope.
Telltale signs of mortar deterioration include mortar erosion exceeding ¼”, crumbling mortar, voids in the mortar, and hairline cracks in the mortar and bricks. These signs should not be ignored. To ensure there’s no further damage to the building, repointing should be performed as soon as possible.
While repointing is necessary, it’s erroneous to assume that repointing alone will solve all building envelope deficiencies. Water entry can result from deficiencies in flashing, waterproofing, gutters, lintels, sills, sealant joints, etc. It’s important to determine the root causes of any observed deterioration, and the sources of water infiltration, prior to performing any repair work. Our estimator will do this for you. Without eliminating the source of the problem, mortar deterioration will continue, and repointing efforts will be a waste of time and money.
In most cases, the project costs associated with external restoration of a building are relatively low in relation to the benefits, particularly, the increase in property value and subsequent resale factor. Additionally, the reduction in risk, or potentially costly structural defects, outweigh any immediate costs.
