Surface by surface
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, so the sealant grips the two sides only.
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, tray edges and screen profiles included.
Remedial sealant for homes and businesses in Tonge
If a joint has been resealed and is leaking again, it’s worth a proper look. It helps to have pictures when you phone 0345 464 0079 or send us an email. Typical jobs include smears and lumps from a botched reseal and a shower that leaks however often it’s resealed, across mouldy bath & shower sealant, failed movement joints and leaking tray & enclosure joints.
Somewhere as small as Tonge, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Bathrooms and kitchens in Tonge
Tonge 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, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For site and facilities teams at buildings such as Sittingbourne Community College, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. In the older streets around Church of St Giles, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Letting a property close to Teynham station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Run the fan after every shower
- Look for stains below bathrooms now and then
- Never seal over old silicone
- Keep bleach and abrasives off the bead
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
How we quote for remedial sealant

Leave it or put it right?
Remedial work takes longer than a straight reseal, but not by much: the work takes a few hours, depending on how many layers have to come out. It’s far less disruption than resealing the same joint again and again. Older cottages and farmhouses around Tonge can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Will you leave a mess?

What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
How it works
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. It normally takes a few hours, depending on how many layers have to come out. Somewhere like Tonge needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints
