Professional Repointing

Repointing Chimneys and Walls

Repointing is the replacement and renewing of the outer portion of mortar joints in brickwork or stonework. Repointing is usually carried out on external walls of properties or chimneys because over time the weather can cause decay of the mortar between the brickwork or stonework. The decay of mortar creates gaps between the masonry units which are usually bricks or stone - depending on the age of your property - this is where rain, snow, ice and hail - and any other undesirable types of weather - can enter the property causing damage to the walls, roof or chimney.

It’s crucial to the stability and weather-proofing of a roof or wall to ensure the pointing is always in good condition. So, if you are in any doubt, call Roof Smart and we will visit your property to assess what, if anything, is required.

Leaky roof or chimney

If you are having problems with a leaky roof, and you have a chimney, it may be that repointing the chimney is the solution however without seeing the problem first hand it’s difficult to say. With many years’ experience in repointing, RoofSmart offers site visits to establish if repointing of your brickwork joints is required. We will also discuss the type of mortar your external or internal walls will require to enable the very best repointing.

What is used to repoint a chimney or wall?

Vertical joints or thin joints are repointed by hand or with small power chisels. If a power saw is required it will only be used on wide and uniform horizontal joints and in the middle of the joint. A hammer and chisel are then used for the rest of the mortar, closer to the masonry units the bricks or stones, depending on the construction of the property walls.

Mortar pointing

Well-built clay brickwork is virtually maintenance free. The brick colour will not fade and the only obvious repairs maybe after many years the mortar joint faces may require re-pointing. However, if the correct mix proportions are used appropriate to the exposure factor, this will not be for many years.

Chimney repointing repair costs

Chimney are always in the most exposed location on a property and therefore experience considerable weathering. This can include wind-driven rain, hail, ice and snow in the winter to extreme heat from sunlight in the summer (or heavy rainfall – after all, this is the UK).

These weather conditions is why mortar on chimneys between the bricks often fails earlier than any other part of the home.

Once the chimneys mortar has failed, call Roof Smart to fix it because water may leak into your loft and bricks, cowls and aerials may come loose.

Chimney repointing is a process whereby the original failed mortar is raked out and replaced with new mortar.

The cost of chimney repairs and time allowance really depends on how big the chimney is, and how damaged the original pointing is. In addition, you may need additional work done such as cutting out and replacing damaged bricks or stone work, replacing leadwork or nearby roof tiles.
