Mastic man in Canterbury

Sealant jobs we do in Canterbury

Canterbury packs a lot of different homes into a small city: timber-framed houses inside the old walls, period terraces, post-war houses rebuilt after the Blitz and a growing ring of new estates. Mr Mastic is based in Crawley and covers Canterbury as part of our Kent work, resealing baths, showers and kitchens, renewing window and door mastic and sealing external joints.

Whatever the age of the building, the method is the same. Every trace of the old sealant comes out, the joint is cleaned and left dry, and a fresh bead goes in that suits the surfaces either side of it. Where a bathroom has a coloured suite or a particular grout shade, we can match it with colour-matched resealing, which matters in older houses where bright white silicone can look out of place.

Medieval streets, Victorian terraces and a new southern edge

The Canterbury City Conservation Area covers more than 125 hectares and holds over 760 listed buildings, many of them inside or just beyond the city walls. Streets such as Palace Street still have 16th-century timber-framed houses, often refronted over the centuries. Frames in these buildings move with the seasons, and bathrooms squeezed into them tend to sit on timber floors with uneven walls. A soft, flexible bead copes with that far better than a hard one, and on listed or painted joinery we’ll talk through whether a paintable sealant is the better choice.

The city was badly hit in the Second World War. More than 700 homes were destroyed in air raids, the worst on 1 June 1942, and rebuilding in the centre began roughly a decade later. That leaves post-war houses and flats sitting beside much older neighbours, and plenty of replacement uPVC windows whose mastic is now hard, cracked and shrinking back from the brick.

Growth is now on the edges. The council’s local plan allocates around 4,000 homes at Mountfield Park in south Canterbury, with further sites at Thanington and the former Howe Barracks. New homes settle in their first couple of years, and builder sealant around showers and baths often splits as they do.
