Different surfaces, different methods
Movement & expansion joints
A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We work carefully to avoid adding to it, and tell you about any damage we find.
The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours, depending on how many layers have to come out. In a smaller place like St John Street area, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- 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.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Don’t add new sealant on top of old
- Check trays and worktops don’t move
- Get the cause of a repeat leak found before resealing
- Keep an eye on the ceiling below the bathroom
Go easy on the new sealant: a mild cleaner and a soft cloth, with no blades or scourers.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
For landlords and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
When to call us in St John Street area
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
Most people get in touch after spotting one of these:
- Mould trapped under a layer of silicone
- Floor or wall movement joints that have failed
- Beads that never stuck properly
- A shower that leaks however often it’s resealed
For an older house near a landmark such as Pusey House Chapel, older homes can move a little, which is hard on rigid grout and tired sealant.
Questions to ask before booking
- What the quote includes, VAT included or not
- What happens if the job turns out different
- When the joint can take water or movement
- How the colour is chosen
When it isn’t the sealant
It helps to know what we cannot do:
- Movement from fittings that aren’t supported
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Older mastics that may need an asbestos check before removal
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly.
Surfaces we seal
- Mouldy bath & shower sealant
- Botched or over-sealed joints

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
