What happens if it’s left?
Ripping out a bathroom is not normally needed. If the bath, tray and tiles are sound, remedial resealing generally puts it right. If they’re not, we’ll tell you. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Forest Gate, the repair is bigger than a sealant job.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

Remedial sealant for homes and businesses in Forest Gate
Two decades of sealant work means we recognise most failures quickly. We are fully insured ARBOMaster approved applicators, and every remedial job comes with a 12-month guarantee. If you have sealant applied over old sealant that has lifted and worktop sealant that has shrunk and split, we can help, whatever the surface.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Forest Gate, remedial sealant is as much about a room looking cared for as about keeping water out.
Your job is guaranteed for a year, as with all our work.

Forest Gate: your questions answered
I let a flat near Wanstead Park station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Is parking a problem for a job in Forest Gate?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Can you fix a reseal that hasn’t worked?
Yes. There’s usually a reason: sealant over sealant, movement or another leak, so we find that first.
How do I get a quote for remedial sealant in Forest Gate?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Where do you work from?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can you remove sealant that is been put over old sealant?
Yes. Each layer is cut out and the residue cleaned off, before resealing with a single bead.
How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours, depending on how many layers have to come out. In Forest Gate, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- 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
- Tell us about any water getting in
- Mention any parking rules near the property
- Mention if the joints have been sealed before
How to get a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Advice
Forest Gate homes and their sealant
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. London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For an older house near a landmark such as A Radical Church, older homes can move a little, which is hard on rigid grout and tired sealant. As a London address, Forest Gate can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For landlords with property near Wanstead Park station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Check ceilings under showers for marks
- Get the cause of a repeat leak found before resealing
- Do not wait for a small gap to become a leak
- Report a tray that rocks or a worktop that lifts
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
Honest limits
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Older mastics that may need an asbestos check before removal
- Water damage behind tiles that needs a tiler
- A tray or worktop that needs refixing first
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
What we seal
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Failed movement joints
- Expansion joints
- Mouldy bath & shower sealant
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
