What good tuckpointing looks like
Keeping the new mortar no stronger than the old
There is a second limit worth knowing. The brick industry's maintenance guidance says repointing mortar should be equal to or lower in strength than the original mortar in the wall. A stronger mix concentrates stress where mortar meets brick and can spall the brick face.
We look at the existing mortar, its hardness and how it has weathered before choosing the repair mix. Where the original is unusually soft, the new mortar has to respect that. We explain the choice in plain words and record it in the written record of the work.
Hand chisels and the gentlest mortar removal
Federal preservation guidance describes hand chisels and mash hammers as the least damaging way to remove old mortar. The work is slower, but it poses the least risk to the brick edges. On many chimneys that care is what keeps the finished job looking right.
We use hand tools wherever the brick or the joint calls for them. On very hard mortar or wide horizontal joints, a skilled hand with a suitable tool can help. We explain the method we plan to use and how the brick edges will be protected.
Pre-hydrating the mortar before repointing
Repointing mortar is usually mixed in two stages. Brick industry and federal preservation guidance both describe adding just enough water to make the dry mix hold together, letting it stand, then adding the rest. This reduces shrinkage once the mortar is in the joint.
Less shrinkage means fewer hairline gaps between the new mortar and the brick. It is a simple step that takes planning, because the mix has to rest before use. We build it into the day so the joints receive mortar that is ready rather than rushed.
Protecting fresh joints from heavy rain
Freshly tooled mortar is soft at the surface. Heavy rain can wash out fine material, streak the brick below and leave joints rough. Covering the work is part of the job when showers are likely.
If rain threatens, we protect the day's joints before we leave and may shift the schedule. We would rather lose a few hours than redo a face of joints. Tell us if you notice covers moved by wind, so we can reset them promptly. A face of joints protected for a day is worth the small delay.
What your tuckpointing estimate lists
- Mortar chosen to suit the brick
- Pre-hydrated mortar placed in thin layers
- Access plan for the stack above the roof
- Workmanship warranty on the agreed joints
Questions to ask before repointing
Do you use power tools to remove old chimney mortar?
Hand tools are the least likely to damage brick edges. Power tools can help on some horizontal joints in skilled hands, but head joints are cleared by hand. We explain the method before work starts.
Why do some joint shapes hold up better on a chimney?
Concave and V-shaped joints are pressed tight against the brick when tooled, which helps them resist water. Recessed or ledged joints can hold water on the face. We discuss matching the existing look against weather resistance.
Is face grouting an option for fine joint cracks?
Brick industry guidance describes surface grouting for small hairline cracks. It changes how joints look, making them a little wider and smoother. Repointing is generally recommended because it suits more kinds of joint damage, and we explain which fits yours.
