Sittingbourne, Kent

Mastic Sealant Specialist in Sittingbourne

Sharp lines, mould-resistant silicone and a finish that lasts. The Mastic King covers all of Sittingbourne and the surrounding ME9–ME10 postcodes — same-day visits available.

Sittingbourne sits in the Swale borough between Chatham and Canterbury, and we're in the area regularly — it's a natural stop on our route between the two. We cover the full ME9–ME10 postcode range, including Kemsley, Murston, Bapchild and the surrounding villages. Sittingbourne has a mix of housing stock — post-war estates, 1970s and 1980s semis, and a growing number of new-build developments on the town's edges. Each type presents its own sealant challenges. Older properties often have original bathroom suites where the silicone has never been properly replaced. New builds frequently have builder-applied sealant that fails within a year or two. We handle both. Kitchen worktop sealing is a regular job in Sittingbourne — particularly in homes that have had new worktops fitted and need a clean, watertight seal around the sink. We also carry out a lot of window frame mastic work across the town, particularly on the older housing stock where the original sealant has cracked and shrunk. Letting agents and landlords in Sittingbourne use us regularly for end-of-tenancy refreshes and planned maintenance. If you manage properties in the ME9 or ME10 area, get in touch about a maintenance schedule.
