About our mastic sealing in Cadmore End
Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. Most enquiries involve estate-wide sealant that is simply worn out and movement joints with sealant missing, on shopfronts below residential blocks, window and door perimeters on blocks and balcony and threshold joints. A single leaking joint is often how a building in Cadmore End first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Cadmore End, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.
