About our remedial sealant in Wallingford
If a joint has been resealed and is leaking again, it’s worth a proper look. Send pictures when you ring 0345 464 0079 or send us an email, and say how long ago it was last done. If you’re dealing with kitchen joints letting water behind the worktop and a shower that leaks however often it’s resealed, we can help, on leaking tray & enclosure joints, shrunken worktop sealant and botched or over-sealed joints alike.
In a smaller place like Wallingford, homes are mostly houses and bungalows rather than flats, some older and some much newer. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
All of our work is guaranteed for twelve months.

Different surfaces, different methods
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. Taking it back shows what’s underneath.
Mouldy bath & shower sealant
Repeat mould generally points to a damp, poorly aired room. Along with resealing, we’ll mention if the room needs better ventilation.
Your questions about remedial sealant in Wallingford
Do you work for landlords with property near Cholsey station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Do you cover smaller places like Wallingford?
Yes, Wallingford is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can failed expansion joints be resealed?
Yes. The depth is set with backing so the sealant only bonds to the two sides, which lets it stretch.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Can you fix a reseal that hasn’t worked?
Yes. We’ll take all the sealant out, look for why it failed and reseal it properly.
Does remedial work come with a guarantee?
Yes. Our 12-month guarantee covers the work, and we are fully insured.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Landlord and commercial work in Wallingford
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
We work for landlords and letting agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
Looking after it afterwards
So the new joints stay in good condition:
- Do not wait for a small gap to become a leak
- Keep an eye on the ceiling below the bathroom
- Air the bathroom so the sealant can dry
- Report a tray that rocks or a worktop that lifts
Do not let anyone seal over it later. Over-sealing is how many remedial jobs start.
Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Each one is worth getting looked at.
Honest limits
A few problems are outside what sealant work can do:
- A leaking trap, valve or supply pipe
- Cracks in the fitting rather than the joint
- Movement from fittings that aren’t supported
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.

What else we do in Wallingford
What happens if it’s left?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. Around Wallingford, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

What we do, step by step
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a typical bath or shower, longer where several layers have been applied in most cases. A visit to Wallingford is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access
- For business premises, tell us about site rules or sign-in
How to get a quote

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.
For site and facilities teams at buildings such as Fir Tree Junior School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. In the older streets around St Mary-le-More, walls and floors in older homes can move, and sealant and grout show it first.
