Remedial sealant in London Fields
In London Fields, as anywhere, remedial jobs tend to look alike: 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. If you are dealing with smears and lumps from a botched reseal and over-sealed joints coming away, we can put it right, on shrunken worktop sealant, leaking tray & enclosure joints and failed movement joints alike.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In London Fields, remedial sealant is as much about a room looking cared for as about keeping water out.
All of our work is guaranteed for twelve months.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Get the cause of a repeat leak found before resealing
- Check ceilings under showers for marks
- Keep the room well ventilated
- Never seal over old silicone
If the joint ever needs renewing, have it cut out, not sealed over. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
How the job changes by surface
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. We strip it, degrease the joint and reseal colour-matched to the worktop.
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.
What happens on the day
At the end, we look at the finished work together. The work normally takes a few hours for most joints, depending on how much old sealant has to come out, depending on how much there is to do. In London Fields, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
How to prepare
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

What affects the cost of remedial sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How easy the joints are to reach
- Which sealant suits the joint
- The old material and how stubborn it is
- Any working-time requirements on site
Doing several joints on one visit is normally more efficient than separate visits. We will give you a clear price for the lot.
Asking for a quote
There’s no need for technical detail. Just tell us:
- Pictures of the joints, sent by email
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel

Can I do it myself?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
FAQs for London Fields
I live in a flat in London Fields. Can a failed seal leak into the flat below?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Do you work for hotels and guest houses in London Fields?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Are you insured?
Yes. We’re fully insured for every job we do.
Can old silicone be taken off without scratching the tiles?
Yes. Careful removal is most of a remedial job, especially on acrylic, enamel and uPVC.
Can you remove sealant that’s been put over old sealant?
Yes. Each layer is cut out and the residue cleaned off, before resealing with a single bead.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. There’s generally a reason: sealant over sealant, movement or another leak, and we deal with the cause first.

Bathrooms and kitchens in London Fields
London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early.
Homes close to Church of St Michael and All Angels include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. If you look after a building such as Gayhurst Community School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Leave it or put it right?
Hidden water does the most damage: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. In a flat in London Fields, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
