Mastic is the seal between the window and the fabric of the building, which keeps out the wind and rain and also forms an important seal to eradicate draughts and reduce noise. We can offer expert advice on any type of mastic, from traditional burnt sand mastic to the modern flexible mastics. As soon as this seal starts to decay, water ingress can begin and can cause many problems inside the building.
Our Mastic service is in house. This means we have total control of the process and not reliant on sub-contractors.
There are different types of mastic which need to be used for specific buildings. Listed buildings, for example, require traditional burnt sand mastic to be applied. When a project requires this type of mastic, we use only the finest Masons Mortar products and apply this, using precise specifications.
For modern and non-listed buildings, we use a more flexible mastic, which has up to 20% movement accommodation and is ideal for sealing the area between the window and the stone. This flexible mastic is much more suitable, allowing for the timber to contract and expand without cracking and can also be painted over.
We offer professional advice and installation and all work is fully guaranteed.
