What is repointing? In masonry construction, repointing refers to the process of renewing the external parts of mortar joints. Repointing is an essential exterior maintenance service since weathering and decay causes voids in masonry unit joints, more so bricks, overtime. This can cause aesthetic problems as well as water seepage. Repointing involves the careful removal and replacement of deteriorated/damaged mortar from masonry wall joints.
For a repointing job to stand out, the deteriorated mortar must be removed carefully and replaced with an intelligently formulated mix. This is an incredibly sensitive process which explains why repointing must be left to true professionals. Furthermore, bad repointing can cause structural damage.
Inappropriate mortar mixes can accelerate deterioration rather than preserve masonry. Knowing the performance characteristics as well as the original mortar ingredients is paramount! That’s where we come in.
We start by analysing your brickwork mortar to identify the original mix. We proceed by formulating the perfect mortar recipe that matches the original mix/building. We pay special focus on aesthetical appeal as well as durability. We sample and test original mortar mixes using traditional methods. We also offer brickwork repair services where necessary.

We utilise a variety of pointing styles when restoring historic brickwork. We can repoint historic sites and buildings using a number of traditional styles. We can also use these historic methods to give new buildings a classic look.
Double struck pointing or bird beak pointing is a historic finish that dates back to the 15th and 16th century. The finish, which was created using a pointing trowel, was popularly used to get rid of brick irregularities during this period.
Struck pointing which is also known as overhand struck pointing is a joint finish dating back to the 17th century. The finish, which isn’t considered impressive today was popular when brick irregularities were common because brick making was reasonably poor. Struck pointing was used to define straight lines on top arise of bricks.
We can also offer you tuckpointing services. Tuckpointing was originally designed to imitate gauged and rubbed brickwork, using cheaper bricks. The finish style dates back to the 17th century. Brickwork joints would be filled using coloured mortar matching the brickwork for purposes of hiding irregularities. Lines would then be scribed and fine lime putty ribbons laid into the grooves to offer the effect of a 5mm joint.
Weather struck or cut pointing is a relatively new brick finish that became popular when bricks irregularities decreased (in the late 19th century). As the name suggests, the finish was designed to weatherproof brickwork (help brickwork shed water away). Weather struck pointing was created using a trowel, at an angle to offer defined straight lines.
We also do new traditional builds for clients wishing to create extensions on historic property. For this service, we employ traditional techniques and materials such as natural lime mortars ensuring we match original buildings in every way including character and appearance.
