What is Repointing?
Repointing is where the outer face of the mortar is replaced. Overtime and exposure to the elements it can decay which can allow for the ingress of water and damp.
It is easy to damage brickwork by inappropriate pointing, therefore it is important to use both the correct method and mixture.
Our method of re-pointing is often thought of as a simple form of work but this craft dates back to the Roman era and it is essential to understand the correct methods.
Our expert team will select the correct materials suitable for the specific building.
How do I know if my property needs repointing?
A general guide is that you measure the depth of the disintegration against the height of the mortar. If the depth matches the height of the mortar filling then you should seek advice.
Old Lime Mortar Repointing
Many older brick properties were built with lime mortar, for example Victorian properties were often built with lime mortar, not cement. It is essential that you get professional advice when repointing, as not using the correct mortar can cause property damage.
Lime mortar allows the house to breath, using cement mortar waterproofs the joints making it difficult for moisture to escape which can cause damp and rotten bricks.
Matching
We also offer brick/stone matching service, going to great lengths to find the original materials used so BA can restore your property back to its original glory. Restoration in brickwork can differ slightly from stonework, but the basic principles remain the same.
Mortar Bees
Mortar bees dig holes in mortar, usually soft stone or sandy mortar. They excavate tunnels in the mortar, which can have devastating effects on the structure and stability of the wall. The bees excavate or enlarge holes throwing out the spoil behind them. In extreme circumstances, the annual burrowing activities may cause an extensive system of galleries and this can disrupt the bearing capacity of the masonry. The holes fill with water which expands when it freezes and causes further deterioration.
Repointing the wall with a suitable mortar will prevent access by the bees and prevent further deterioration.
