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 that we can handle for you.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
Remedial sealant in City of Westminster, done properly
Remedial jobs in City of Westminster generally fall into a few patterns: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. We work on shrunken worktop sealant, mouldy bath & shower sealant and failed movement joints, and common reasons people get in touch are over-sealed joints coming away and caulk or the wrong sealant used in a wet area.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. For a bathroom or kitchen in City of Westminster, getting the joints right keeps water where it belongs and the room looking clean.
Big or small, you get the same one-year guarantee.

When something else is needed
Sealant is not the answer to every problem, and we will tell you before work begins. It will not solve:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A bath, tray or worktop that moves until it’s properly fixed
- A cracked shower tray or bath (that needs repair or replacing)
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
What we seal
- Failed movement joints
- Expansion joints
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most joints, depending on how much old sealant has to come out, and the area is left clean. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We start by checking the joint for movement, leaks and the reason it failed.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children

When to call us in City of Westminster
Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.
If you can see any of these, it’s time to have the joints looked at:
- Worktop sealant that has shrunk and split
- Dark patches showing through the sealant
- Movement joints that have split or pulled away
- Thick, messy sealant smeared over tiles
Managing a site like St Vincent's Catholic Primary School? Then 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.

Keeping the joints in good condition
So the new joints stay in good condition:
- Always have old sealant cut out, not covered
- Do not wait for a small gap to become a leak
- Run the fan after every shower
- Keep an eye on the ceiling below the bathroom
Keep an eye on the joint at first, particularly where the original failure was caused by movement. Should anything change, ring 0345 464 0079 or email us.
If a joint has failed more than once, stop resealing it. Get the cause found first, or the next bead will go the same way.

A frame that keeps leaking may not be the mastic. If the frame joint isn’t the cause, we’ll say so.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated.
