Masonry work can be performed in sub-zero temperatures under certain conditions.  There are additives that can be added to allow the cement to properly cure in temperatures as low as -5 degrees Celsius.  You can also build an enclosed space similar to a tent around the area that you are working and install a heating system. Generally, if the temperature is below 0 degrees Celsius the water in the cement will freeze before it has time to dry which will damage the final product.

Tuck pointing is the task of replenishing and/or restoring the mortar between bricks, blocks, or stones on your property. Tuck pointing can be performed on both vertical and horizontal masonry surfaces. (walls or walkways)

Parging is a protective coat of cement which is usually applied over the top of the foundation of a building.  It can be applied to both the exterior and interior of a building.  Parging can also be applied to improve the aesthetic value of a wall.

You should consider replacing your bricks when you notice deterioration on the face of your bricks.  Even if you notice that one or a small group of bricks has deteriorated it is a good idea to have a repair done. Quite often deterioration starts in a smaller patch and spreads outwards to surrounding bricks over time. 

There are a number of reasons to repair your chimney.  

– If your chimney is noticeably leaning you should look into having it rebuilt.  A leaning chimney poses a safety threat to you and your neighbors.  

– A chimney with deteriorated bricks should also be repaired. Over time this can lead to a situation where bricks are no longer secured to the chimney and eventually become a threat to fall. 

– A damaged chimney cap should also be repaired. The chimney cap is the chimney’s primary protection from moisture.

– If your chimney does not have a proper concrete or stone cap one should be installed.

– If the mortar joints on your chimney are slightly deteriorated you should consider having a professional perform tuck pointing repairs. If the mortar joints are severely deteriorated the structural integrity of the structure may be compromised and a full chimney rebuild might be in order.

– If your chimney is leaking into your house then repairs are needed. This can stem from issues with the cap, flashing, or bricks.

Water is the biggest threat to masonry in Canada.  If there is a leaky downspout or some other factor leading to excessive moisture exposure; water will find its way into the small nooks of your wall or walkway.  In the winter months if your wall is saturated or is holding moisture the water will freeze and expand.  As a result, masonry will often flake, chip, or crack.
