Repointing is simple in principle — remove failed mortar and replace it — but the quality is all in the detail. Here's how a typical job runs.
Survey and specification. We look at the age and type of brick, the existing mortar, how exposed the wall is and the original joint profile. That decides the mortar mix (lime or cement-based), the colour and sand match, and the finish. Listed or conservation-area properties may need the specification agreed with the council first.
Access. Depending on height, that means towers or scaffolding, with protection for windows, plants and paths.
Raking out. Old mortar is removed to a consistent depth — generally at least twice the joint height — taking care not to damage the brick edges. Widening joints with careless grinding is one of the most common causes of ugly, failing repointing.
Cleaning and dampening. Joints are brushed clear of dust and lightly wetted so the new mortar isn't dried out by thirsty brick, which would weaken the bond.
Pointing. New mortar is packed in firmly in layers on deeper joints, then finished to the agreed profile, such as flush, bucket-handle or weatherstruck.
Curing and tidy-up. Lime mortar in particular needs protecting from sun, wind, rain and frost while it cures. Once firm, joints are brushed back and the site is cleared. The result should look like it belongs on the building, and protect it for decades.
