Pointing is the mortar infill between the masonry. It is the primary weather proofing of the facade, and is very important to the structural integrity of the building. We can undertake partial or total re-pointing.
Sometimes, if the pointing between brickwork is so weak that running your hand across loosens it, then the action of the brushes applying the chemicals, and the spraying off will make matters worse, and you should be re-pointing it anyway.
We can org anise patch pointing (redoing the missing bits) or whole scale re-pointing of the entire facade (We find that a lot of developers will deliberately re-point even moderately good pointing so as to present a fresh even appearance).
Pointing styles and colour vary according to individual client taste, but we recommend that smallest, most unobtrusive joint so as to emphasis the brickwork.
