Remedial sealant in Woodside
If a joint fails again and again, something is causing it. A tray that moves, a worktop that isn’t fixed, the wrong sealant or water getting in elsewhere will defeat even a perfect bead. Finding that cause comes before any new sealant. If you have smears and lumps from a botched reseal and dark patches showing through the sealant, we can put it right.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Woodside, remedial sealant is as much about a room looking cared for as about keeping water out.
There’s a 12-month guarantee on every job, large or small.

Do you need remedial sealant in Woodside?
Water from somewhere else can ruin a good seal. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
Any of these means the joints need attention:
- Floor or wall movement joints that have failed
- Products that weren’t meant for the joint
- Gaps opening along the back of the worktop
- A second bead peeling off the first
For site and facilities teams at buildings such as St Thomas Becket Catholic Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What happens on the day
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours, depending on how many layers have to come out, including the tidy-up. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Woodside. It helps if you can point us to a visitor permit or a bay close to the door.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
Preparing for the visit
- Move anything stored near the joints
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can

Questions from Woodside
Do you work for landlords with property near Norwood Junction station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Could a tired shower seal in my Woodside flat affect the neighbours below?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that is down. Cutting out the old sealant and laying a new bead early stops it getting that far.
How long does the work take?
It takes a few hours, depending on how many layers have to come out. You will know the timing when we quote.
Can you fix a reseal that hasn’t worked?
Yes. We check it’s the sealant and not the tray, valve or waste, then strip and reseal the joints.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
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, and we will not reseal for the sake of it.
When is the sealant fully cured?
Cure times vary by product. We tell you how long to leave it before we go.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
Places near Woodside
What else we do in Woodside
Different surfaces, different methods
Movement & expansion joints
Joints filled with mortar, grout or rigid filler cannot move. Where it can be raked out, we replace it with flexible sealant.
Worktops & kitchens
A loose worktop splits its sealant. That needs refixing before resealing, which we’ll point out.
Woodside homes and their sealant
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. 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.
For an older house near a landmark such as Church of St Luke, walls and floors in older homes can move, and sealant and grout show it first. For landlords with property near Norwood Junction station, botched sealant from a previous quick fix is easier to strip out between tenants.

Looking after it afterwards
So the new joints stay in good condition:
- Report a tray that rocks or a worktop that lifts
- Use a soft cloth, not a scourer, on silicone
- Never fill a movement joint with mortar or grout
- Do not wait for a small gap to become a leak
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
What happens if it’s left?
A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
