About our remedial sealant in Sittingbourne
Getting old sealant out properly is slow, careful work. We cut out every layer, clear the residue and degrease the surfaces, without scratching tiles, trays or frames. Only then can new sealant bond. We are often asked to deal with sealant that came away because the surface wasn’t prepared and mould trapped under a layer of silicone, on shrunken worktop sealant, botched or over-sealed joints and failed movement joints.
Sittingbourne mixes older houses with estates built more recently, and bathrooms range from decades-old suites to brand-new ones. Whatever their age, sealant and grout tend to go before anything else.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

When to call us in Sittingbourne
Using the wrong product is a common cause: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. Each fails in its own way.
The most common problems we see are:
- Sealant peeling off a dusty or damp surface
- Worktop sealant that has shrunk and split
- Wide, uneven beads that look worse than the old ones
- Movement joints that have split or pulled away
Homes close to Church of the Holy Trinity include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
Questions to ask before you book
- How the colour is chosen
- How hidden problems are handled
- What insurance they hold
- How long to leave it before use
What happens on the day
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for most joints, depending on how much old sealant has to come out. For a job in Sittingbourne, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
How to prepare
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we are working on

Remedial sealant around Sittingbourne
Sittingbourne is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Rented homes near Sittingbourne station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Schools such as Borden Grammar School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Different surfaces, different methods
Movement & expansion joints
Joints filled with mortar, grout or rigid filler can’t move. We rake that out where it can be removed and seal with a flexible product.
Over-sealed & botched joints
Every layer has to come out, and silicone residue is cleaned off the tiles too. Only a clean joint will take a new bead.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Always have old sealant cut out, not covered
- Do not wait for a small gap to become a leak
- Keep movement joints clear of mortar and paint
- Air the bathroom so the sealant can dry
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
