Weathered mortar joints in a brick chimney

OnPoint RoofCare · Lanarkshire & Glasgow

Chimney Repointing

Open or crumbling chimney joints need a closer look before mortar is renewed. OnPoint RoofCare assesses the affected masonry, nearby flashing and top of the stack, then explains the areas that need repointing and any separate repairs the chimney requires.

When to Ask About Chimney Repointing

Tell us what you have noticed and when it happens. These signs help guide the inspection; they do not establish the full repair from a photograph.

Missing or deeply weathered mortar joints
Pieces of mortar found below the chimney
Local cracks around previously repaired pointing
Damp near the chimney requiring investigation

Send photographs taken safely from inside or ground level. Keep clear of loose material and leave roof access to appropriately equipped professionals.

Choosing the right work

Target the failed joints

One exposed face may be more weathered than the rest of the chimney. We look at the condition and extent of failed joints rather than assuming every part needs renewal. Close photographs help explain which areas are included and which remain serviceable.

A stain indoors does not on its own prove the pointing is responsible. The stack’s top and roof junction also need consideration so the recommended work addresses the observed defect.

Choose a suitable mortar and repair scope

Mortar colour is only one part of a successful match. The specification needs to suit the masonry, existing construction and exposure. Ask what is proposed, how joints will be prepared and how the work will be protected while it cures.

Access, height, chimney size and the extent of deterioration affect the quote. Pot security, damaged bricks, flaunching and flashing repairs should be listed separately where needed. This makes the work understandable and prevents a small pointing enquiry from becoming an undefined package.

A defined scope

What Your Quote Can Include

The work is agreed from the findings. Depending on the property and required repair, the scope may include:

Identifying failed joints and retaining sound pointing
Discussing mortar suitable for the existing masonry
Preparing the agreed repair areas carefully
Repointing specified chimney faces or sections
Checking adjacent pots, weathering and leadwork within the agreed scope

Height and access, the extent of damage, suitable materials and concealed layers affect the price. Ask what is included, what remains uncertain and how any additional work will be agreed.

Before you book

Chimney Repointing: Your Questions

Does soft mortar always need replacing?

No. Sound traditional lime mortar should not be removed just because it feels softer than cement. The condition and loss of the joints need assessment.

Will repointing stop chimney damp?

It may address water entry through failed joints, but other chimney defects or internal moisture issues can also cause damp. The cause should be investigated first.

Will access equipment be needed?

Height, roof pitch, position and the work determine safe access. The quote should explain the access arrangements rather than assuming a ladder is sufficient.
