Bathroom resealing for homes and businesses in Southfleet
Mr Mastic has more than 20 years’ experience of sealant work, and our applicators reseal bathrooms and kitchens across Southfleet. We are fully insured ARBOMaster approved applicators, and every job carries our 12-month guarantee. We work on shower trays & enclosures, kitchen worktops & upstands and baths, and common reasons people get in touch are water getting behind the kitchen upstand and lumpy, uneven sealant from a DIY attempt.
For a small place like Southfleet, bathroom resealing is planned like any other job: it just means planning the journey and access beforehand. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Leave it or put it right?
A failed joint gets more costly to put right the longer it’s left. Once water is behind the bath, it can reach floorboards, panels and the ceiling underneath, and that’s a far bigger job than a reseal. In a small place like Southfleet, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear price before any work starts.

The process
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before we start. Most jobs take around two hours for one bath or shower, longer for a whole bathroom. In a small place like Southfleet, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Protection goes down around the bath, shower or worktop.
- Old sealant is sliced away and the residue removed.
- We treat any mould and let the joint dry properly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
- Move anything stored near the joints

What bathroom resealing looks like in Southfleet
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Letting a property close to Longfield station? Then mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets. If you live in an older home near Church of St Nicholas, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Do you need bathroom resealing in Southfleet?
Plenty of failed sealant has been laid over the top of older sealant. New silicone won’t bond to old silicone, so it lifts, lets water in and traps mould underneath.
It’s worth asking for a quote if you see:
- Cracked, shrunken or lifting silicone
- Damp behind the bath or under the tray
- Water escaping at the shower enclosure
- Splits where the tray meets the wall
For site and facilities teams at buildings such as Sedley's Church of England Voluntary Aided Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.
What your quote should include
- Which colour the sealant will be
- How long the guarantee is
- What product goes in the joint
- Whether they seal over old material or remove it
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Let new sealant cure fully before it gets wet
- Move toiletries away from the joint
- Open a window or run the fan so the room dries
- Dry the bead with a towel now and then
Don’t stand bottles along the bead, because they trap water against the silicone. A quick squeegee after showering keeps water from sitting on the joint.
Watch for the early signs: lifting ends, gaps, dark shadows under the bead or a stain downstairs. If you spot one, it’s time to reseal.

What else we do in Southfleet
What the job involves on each surface
Wet rooms
Not every wet room leak is a sealant problem. We reseal the joints and will tell you if the water seems to be coming from somewhere else.
Basins & vanity units
Basin joints are short and close to eye level: so we keep the line tidy and even, in white, clear or a colour to suit.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
