Remedial sealant for homes and businesses in Lewson Street
A joint that keeps failing generally has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. Finding that cause comes before any new sealant. We are often asked to deal with smears and lumps from a botched reseal and decorators’ caulk around a bath or shower, on shrunken worktop sealant, botched or over-sealed joints and mouldy bath & shower sealant.
Being in a small place like Lewson Street makes no difference to the job itself: it just means planning the journey and access beforehand. In the bathroom or kitchen, the work is the same as in any town.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. It normally takes a few hours for a typical bath or shower, longer where several layers have been applied. For a village or hamlet like Lewson Street, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you are told about anything else we found.
How to prepare
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can

What happens if it’s left?
DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful removal is most of a remedial job. Around Lewson Street, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we will go through it with you.

Honest limits
We’ll always be straight with you, so here’s what new sealant won’t do:
- A leaking trap, valve or supply pipe
- Sealant in an older building that needs testing for asbestos first
- Water damage behind tiles that needs a tiler
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
What we seal
- Botched or over-sealed joints
- Failed movement joints
- Mouldy bath & shower sealant
- Expansion joints
- Leaking tray & enclosure joints
- Shrunken worktop sealant
Keeping the joints in good condition
Aftercare is simple:
- Have loose fittings fixed before resealing
- Run the fan after every shower
- Deal with small splits early
- Get the cause of a repeat leak found before resealing
Go easy on the new sealant: no scraping, scouring pads or harsh chemicals.
Do not keep resealing the same joint. Get the cause found first, otherwise the next attempt will fail too.
What we are called out for in Lewson Street
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.
Common reasons people contact us are:
- Mould trapped under a layer of silicone
- Products that weren’t meant for the joint
- Gaps opening along the back of the worktop
- Leaks that keep coming back after resealing
For landlords with property near Teynham station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

What remedial sealant looks like in Lewson Street
Lewson Street is within about 3 miles of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around Church of St Mary, timber floors under older bathrooms flex, so joints need a sealant that moves with them. For site and facilities teams at buildings such as Teynham Parochial Church of England Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

How the job changes by surface
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is normally part of the cause. Along with resealing, we will mention if the room needs better ventilation.
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. We remove the failed sealant, fit backing and reseal with a low-modulus product.
