Your staff were a pleasure to have here, and did all they could to explain things clearly and assist us whenever we asked. My wife and I were very pleased with the ease of the process and the general helpfulness of the crew doing the work.

Repointing is the process of reapplying mortar to the seams between bricks and stone walls where the old pointing has started crumbling away. A lot of issues with rising damp, salt damage and wall leakage can be prevented or fixed with repointing. When we do repointing, we always consider a number of issues:
- A good match between the new and old mortar. This prevents any visual oddities, while also ensuring the strongest and most effective bond.
- Material compatibility. Certain combinations might produce unnatural corrosion, flaking or crumbling. This is sometimes the result of contractors failing to conduct adequate analysis of pre-existing mortars.
- Ideal curing time. Depending on the weather that day, the thickness of the wall and several other factors, the new mortar might need to be applied in layers, with a curing time for each. This is one of the areas where experience makes a big difference.
Rising damp is what happens when moisture gets trapped inside the walls, damaging a building from the inside out. It can lead to fungal growth in timber, rusting of metal fasteners, mould, unpleasant smells and structural damage. Finding an effective rising damp solution is all about getting to the root of the problem.
Put simply, we will repair any damage while establishing where the moisture is entering, and prevent it from happening in the future. In most cases, but certainly not all of them, the main issue is that the damp proof course is damaged or missing. This is what ordinarily prevents groundwater from being drawn up through porous walls. Here, we reinstate it with the drilling of and injection of damp cure siliconate, or other methods such as diamond cutting the mortar join and inserting a new metal damp proof course.
