Sealant jobs we do in Sittingbourne
Sittingbourne is growing quickly, and new homes sit alongside brickmakers’ terraces and older village streets. Mr Mastic covers the town and the villages around it from our base in Crawley, resealing bathrooms and kitchens, replacing window and door mastic and sealing external joints on houses, flats and commercial units.
Kitchens are a good place to start. The joint between worktop and wall takes splashes every day, and once it shrinks or lifts, water gets behind the worktop and into the chipboard core. Our kitchen resealing service removes the old bead and uses a food-safe silicone near the sink and hob areas where it’s needed.
Brick, paper and a lot of new streets
Sittingbourne’s older housing grew with its industries. Local clay made it a centre for brickmaking, with as many as 2,628 men in brick and tile making in 1870, and paper was made here from 1708 until Sittingbourne Mill closed in 2006. Terraced houses from that era line many streets near the town centre and in Milton Regis. In 1924 a new paper factory was built at Kemsley with a model village for its workers. Homes of these ages have usually had their bathrooms refitted, sometimes more than once, and we often find sealant laid over sealant, or a bath that has settled and pulled away from the tiles.
The bigger story now is new housing. More homes keep being planned around the town; Swale’s planning committee has, for example, approved 380 homes on land in Tonge, next to the Eurolink industrial estate. New homes settle and dry out in their first years, and the sealant in showers, around baths and at window frames is often the first thing to show it.
If you’ve moved into a new build and the sealant is already cracked or gapping, our new-build sealant snagging guide explains what to look for and when to raise it with the developer.
Low, open land beside the Swale
Sittingbourne lies beside the Swale, the channel that separates mainland Kent from the Isle of Sheppey, and the land around Milton Creek and Kemsley is low and open. Wind off the estuary drives rain at frames and doors, and external mastic on exposed sides of a house ages faster than on sheltered ones. We use exterior-grade, flexible sealants and set them at the right depth so they cope with movement and weather.
Eurolink, Kent Science Park and local landlords
Sittingbourne has a big employment base. The Eurolink industrial estate holds a large number of warehouses, workshops and offices, and Kent Science Park is also in the Sittingbourne area. Units like these need sealant in staff washrooms, kitchens and around windows and cladding joints, and out-of-hours working can be arranged so work doesn’t disrupt the day. Our commercial sealant page has more detail.
With fast trains to London, the town also has plenty of rented homes, and we reseal for landlords and letting agents between tenancies.

Our services in Sittingbourne
- Bathroom & kitchen resealing: Bathroom and kitchen joints taken back to a clean, dry surface and finished with fresh anti-fungal silicone that won’t lift.
- Window & door mastic: Frame perimeters inside and out resealed with flexible, colour-matched sealant, with backing rod where the gap is deep.

- Floor & skirting joints: Movement joints in tiled and concrete floors, and skirting gaps, sealed so they stay tidy and keep dirt out.
- Regrouting: Crumbling grout in showers and wet areas raked out and refilled, so water stays out of the wall behind.

Towns near Sittingbourne
Sittingbourne: common questions
Do you cover Milton Regis, Kemsley and the villages around Sittingbourne?
Yes. We cover Sittingbourne, Milton Regis, Kemsley, Murston and the villages around the town.
My new-build shower sealant has already cracked. Should the developer fix it?
If you’re still within the developer’s snagging or warranty period, report it to them first. If not, we can remove it and reseal with a flexible sanitary silicone.
Can you work in units on the Eurolink estate?
Yes. We seal washrooms, kitchens and external joints in commercial units, and out-of-hours working can be arranged.
Why is there black mould under my kitchen worktop sealant?
Water has usually got behind a shrunken or lifted bead. We remove it, clean and dry the joint and reseal with a mould-resistant silicone.
Do you replace mastic around windows on exposed houses near the Swale?
Yes. We cut out the old mastic and use a weatherproof exterior sealant suited to the frame and wall.
Do you work for Sittingbourne landlords?
Yes. We reseal between tenancies and when tenants report leaks or mould, and can quote for several properties together.
Do you reseal over the old silicone?
Never. New silicone won’t bond to old, so every job starts by removing the old sealant completely.
