How we handle remedial sealant in Pollards Hill
Remedial jobs in Pollards Hill normally fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. Each is stripped back and done again properly. We work on mouldy bath & shower sealant, expansion joints and botched or over-sealed joints, and common reasons people get in touch are decorators’ caulk around a bath or shower and sealant applied over old sealant that has lifted.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Pollards Hill, remedial sealant is as much about a room looking cared for as about keeping water out.
All our work is covered by our 12-month guarantee.

Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.

What remedial sealant looks like in Pollards Hill
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early. Pollards Hill has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.

Signs you need remedial sealant in Pollards Hill
Movement tears sealant that isn’t designed for it. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.
These are the problems we’re asked about most:
- Decorators’ caulk around a bath or shower
- Smears and lumps from a botched reseal
- Gaps opening along the back of the worktop
- A shower that leaks however often it’s resealed
For an older house near a landmark such as St Oswald, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Look for stains below bathrooms now and then
- Keep movement joints clear of mortar and paint
- Have loose fittings fixed before resealing
- Act on a lifting corner straight away
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
What affects the cost of remedial sealant
Every job gets its own quote. These are the things that affect it:
- Which sealant suits the joint
- How many areas need sealing
- Working hours on commercial sites
- Any mould that needs treating
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

When you call or email, these details help:
