How to tell when brickwork needs repointing

Look for changes in the joints

Mortar that is visibly washed back from the brick face, breaking away, cracked or missing may no longer offer the same weather protection. Small local defects can be different from widespread deterioration, so it is useful to note where the change appears and whether it is limited to one exposed elevation.

• Cracked, loose or missing mortar
• Joints that are deeply recessed
• Open gaps around brick edges
• Previous patch repairs that look different from the wider wall

Check the brick as well as the mortar

Brick faces, edges and previous repairs are part of the picture. Spalling, fractured bricks or hard patches can change the repair approach. A quotation should identify whether pointing is the main task or whether brick repair and cleaning are also needed.

Think about exposure and water paths

Chimneys, gable ends and exposed elevations can weather faster than sheltered areas. Gutters, downpipes, rooflines and ground levels can also affect how water reaches a wall. If there is a damp concern inside, the source should not be assumed from external mortar alone.

Give a contractor the right context

A useful enquiry describes the full affected area, shares wide photographs and notes any concerns about water, access or timing. This lets the initial conversation focus on what the property is showing rather than an assumed repair.
