Sewardstone Remedial Sealant
We cover Sewardstone for removing failed, mouldy or leaking sealant and putting it right. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- Leaks that keep coming back after resealing
- Wide, uneven beads that look worse than the old ones
- Sealant that came away because the surface wasn’t prepared
Remedial sealant in Sewardstone
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint won’t last, however tidy it looks. Out it comes, and in goes a sealant suited to the job. If you are dealing with sealant applied over old sealant that has lifted and decorators’ caulk around a bath or shower, we can help, on failed movement joints, botched or over-sealed joints and leaking tray & enclosure joints alike.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Sewardstone, remedial sealant is as much about a room looking cared for as about keeping water out.
Each job carries a 12-month guarantee, large or small.

What happens if it’s left?
Another bead over the top will not fix a failed joint. It doesn’t grip the old layer, so the leak carries on and there’s now more to remove. In a flat in Sewardstone, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Doing several joints on one visit is generally more efficient than separate visits. We’ll give you a clear price for the lot.
Why Sewardstone customers choose us
- Anti-fungal silicone where joints get wet
- Fully insured
- Quality sealants from Arbo and Everbuild
- Any old sealant cut out fully, not covered over

Remedial sealant in Sewardstone: local notes
London has hard water, 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, so tired sealant is best dealt with early.
For landlords with property near Enfield Lock station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Sewardstone is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you look after a building such as Prince of Wales Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

How to look after the new joints
So the new joints stay in good condition:
- Keep an eye on the ceiling below the bathroom
- Clean sealant with mild products only
- Check trays and worktops don’t move
- Keep the room well ventilated
Go easy on the new sealant: no scraping, scouring pads or harsh chemicals.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a typical bath or shower, longer where several layers have been applied. In a London area like Sewardstone, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
How to prepare
- Let us know about parking restrictions
- Mention any tricky access
- For business premises, tell us about site rules or sign-in

Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Questions from Sewardstone
I live in a flat in Sewardstone. Can a failed seal leak into the flat below?
Yes, and the first sign is often a stain on the ceiling below. A proper reseal before the leak starts is the easy fix.
Do you work for landlords with property near Enfield Lock station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
What does remedial sealant cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before work begins.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Can you fix a reseal that hasn’t worked?
Yes. We will take all the sealant out, look for why it failed and reseal it properly.
What if resealing won’t fix my leak?
You’ll hear it from us. If it’s a cracked tray, a failed valve or a leaking waste, resealing will not fix it, and we will not reseal for the sake of it.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
