Cothill Remedial Sealant
Our applicators work in Cothill on removing failed, mouldy or leaking sealant and putting it right. Old material cut out, joints cleaned and sealed neatly.
- Sealant applied over old sealant that has lifted
- Torn expansion joints
- Wide, uneven beads that look worse than the old ones
Remedial sealant in Cothill
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint will not last, however tidy it looks. We take it out and use a sealant made for that joint. If you have sealant applied over old sealant that has lifted and leaks that keep coming back after resealing, we can put it right, whatever the surface.
Around Cothill, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

What else we do in Cothill
What we cannot put right
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Cracks in the fitting rather than the joint
- Movement from fittings that aren’t supported
- Water damage behind tiles that needs a tiler
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.
Joints and surfaces we work on
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Failed movement joints
- Expansion joints
- Botched or over-sealed joints
- Leaking tray & enclosure joints
Why deal with it now?
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 removal is most of a remedial job. In a small place like Cothill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

- Tidy, careful work

How to look after the new joints
So the new joints stay in good condition:
- Have loose fittings fixed before resealing
- Never fill a movement joint with mortar or grout
- Air the bathroom so the sealant can dry
- Keep an eye on the ceiling below the bathroom
Keep the room ventilated: use the extractor or open a window after showering.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a typical bath or shower, longer where several layers have been applied from start to finish. In a small place like Cothill, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We finish neatly and point out anything that needs another trade.
Before we arrive
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height

Different surfaces, different methods
Leaking trays & enclosures
A cracked tray, failed valve or leaking waste needs a different fix. We say so rather than reseal.
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing stops that, so the sealant grips the two sides only.
Common problems we fix in Cothill
Joint depth matters. A bead bonded on three sides, or laid too thick, cannot flex, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
If you can see any of these, it’s time to have the joints looked at:
- Caulk or the wrong sealant used in a wet area
- Leaks that keep coming back after resealing
- Wide, uneven beads that look worse than the old ones
- Mould trapped under a layer of silicone
For an older house near a landmark such as Church of St Helen, walls and floors in older homes can move, and sealant and grout show it first.

Bathrooms and kitchens in Cothill
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 Dry Sandford Primary 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. For landlords with property near Radley station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
