Remedial sealant for homes and businesses in Vale of Health
Getting old sealant out properly is slow, careful work. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. Typical jobs include movement joints that have split or pulled away and sealant applied over old sealant that has lifted, on shrunken worktop sealant, botched or over-sealed joints and leaking tray & enclosure joints.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Vale of Health are no different.
All of our work is guaranteed for twelve months.

Do you need remedial sealant in Vale of Health?
Movement tears sealant that is not designed for it. A bath that flexes, a tray that rocks or a building joint that opens and closes split any bead that is too stiff or too thin.
If you can see any of these, it’s time to have the joints looked at:
- Worktop sealant that has shrunk and split
- Over-sealed joints coming away
- Sealant that came away because the surface wasn’t prepared
- Mould trapped under a layer of silicone
Letting a property close to Hampstead Heath station? Then a joint that keeps failing is best fixed properly while the property is empty.
What to look for in a quote
- How the colour is chosen
- Whether the sealant suits the joint
- What happens if they find a problem under the old sealant
- What preparation is included
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Act on a lifting corner straight away
- Always have old sealant cut out, not covered
- Keep movement joints clear of mortar and paint
- Get the cause of a repeat leak found before resealing
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
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.
Vale of Health homes and their sealant
In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early. London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Vale of Health is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. In the older streets around Christ Church, older homes can move a little, which is hard on rigid grout and tired sealant.

In total, it normally takes a few hours for most joints, depending on how much old sealant has to come out. For a job in Vale of Health, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.

- The new joint is tooled neatly and we explain anything else we found.

What the job involves on each surface
Over-sealed & botched joints

Mouldy bath & shower sealant
Repeat mould usually points to a damp, poorly aired room. We will reseal and tell you if extraction looks to be the issue.
Your questions about remedial sealant in Vale of Health
Can worn sealant in a flat in Vale of Health cause a leak downstairs?
Yes, and the first sign is often a stain on the ceiling below. A proper reseal before the leak starts is the easy fix.
Can you help a landlord with a rental near Hampstead Heath station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
How long should I leave it?
Cure times vary by product and the conditions. Before we leave, we’ll tell you the cure time.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Can you remove sealant that is been put over old sealant?
Yes. We remove every layer; new silicone does not bond to old silicone, which is why over-sealing fails.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What happens if the problem is the tray or the plumbing?
You’ll hear it from us. A cracked tray, faulty valve or leaking waste needs a different trade, so we will not pretend it will.
