Remedial sealant in Rowley Green
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. Only then can new sealant bond. We’re often asked to deal with sealant applied over old sealant that has lifted and caulk or the wrong sealant used in a wet area, on mouldy bath & shower sealant, expansion joints and botched or over-sealed joints.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout.
Whatever the size of the job, you get the same one-year guarantee.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Always have old sealant cut out, not covered
- Keep movement joints clear of mortar and paint
- Ask why a joint failed before redoing it
- Act on a lifting corner right away
Keep an eye on the joint at first, especially if movement was the problem. If anything changes, just phone 0345 464 0079 or drop us an email.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Why deal with it now?
Mould under a bead can’t be reached by cleaning. Removal is the only way to get at it. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

What sealant work can’t fix
We will always be straight with you, so here’s what sealant can’t fix:
- Tiles that have come away from the wall

- Leaks from a shower valve, waste or pipework (a plumber’s job)
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before booking.

Rowley Green homes and their sealant
London’s water is hard, so limescale builds up on sealant, grout and fittings. In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early.
If you live in an older home near Holy Cross, walls and floors in older homes can move, and sealant and grout show it first. As a London address, Rowley Green can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you let a flat or house near Elstree & Borehamwood station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Common questions in Rowley Green
Is parking an issue for remedial sealant in Rowley Green?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Do you work for landlords with property near Elstree & Borehamwood station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or email us.
What if the leak is not the sealant?
Then we explain what we’ve found. A plumber or fitter may be needed.
Someone sealed over the old bead. Can you fix it?
Yes. We remove every layer; over-sealing fails because silicone won’t bond to silicone.
Can old silicone be taken off without scratching the tiles?
Yes, with care. We cut and lift the old sealant with tools suited to the surface, and the residue is cleaned away. Any existing damage is pointed out before work begins.
How the job changes by surface
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is normally part of the cause. Along with resealing, we’ll mention if the room needs better ventilation.
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.
