Mastic sealing in Fulwell, done properly
Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. The enquiries we see most involve repeated reactive repairs to the same buildings and failed external movement joints, across communal kitchens and washrooms, balcony and threshold joints and shopfronts below residential blocks.

Failed sealant in a building in Fulwell can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
