For heritage sites and listed buildings, we use traditional lime pointing and washing methods. Lime mortar also dates back thousands of years, and was also used in the construction of the Egyptian pyramids. We use lime mortar and hot lime to repoint historic buildings to maintain the old methods used in their original construction, and is favoured instead of cement due to its breathability. Lime washing is a painting method we use with this material to add further protection to older buildings from the elements.
