About our remedial sealant in Cranbrook
If a joint has been resealed and is leaking again, it’s worth a proper look. Send photos when you ring 0345 464 0079 or drop us an email, along with when it was last resealed. We work on botched or over-sealed joints, shrunken worktop sealant and leaking tray & enclosure joints, and the jobs we see most are smears and lumps from a botched reseal and a second bead peeling off the first.
Hard London water leaves limescale on sealant, grout and taps alike. In Cranbrook, remedial sealant is as much about a room looking cared for as about keeping water out.
You’re covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Remedial sealant in Cranbrook: local notes
London’s water is hard, which leaves limescale on sealant, grout and taps. Cranbrook has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
Letting a property close to Ilford station? Then botched sealant from a previous quick fix is easier to strip out between tenants. Schools such as The Ursuline Academy Ilford are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What sealant work can’t fix
We’ll always be straight with you, so here’s what new sealant will not do:
- A tray or bath that is cracked
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Movement from fittings that aren’t supported
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before booking.
What we seal
- Expansion joints
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Failed movement joints
Common problems we fix in Cranbrook
One of the commonest remedial jobs is sealant on top of sealant. Silicone doesn’t bond to silicone, so the top layer lifts and water and mould collect between the two.
The most common problems we see are:
- Torn expansion joints
- Dark patches showing through the sealant
- Repeat leaks from the same joint
- Over-sealed joints coming away
Homes close to St Clement's Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.
What your quote should include

Landlords, agents and businesses in Cranbrook
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
What happens if it’s left?
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 London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Cranbrook.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What you get with us
- Sanitary silicone with an anti-fungal additive in wet areas
- 180+ five-star Google reviews
- Sealant colour chosen to suit
- White, clear, grey or another colour, product permitting

Your questions about remedial sealant in Cranbrook
Can worn sealant in a flat in Cranbrook cause a leak downstairs?
Yes, and the first sign is often a stain on the ceiling below. A proper reseal before the leak starts is the easy fix.
Is parking an issue for remedial sealant in Cranbrook?
Parking in Cranbrook, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
What does remedial sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Do you work for letting agents?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels.
Someone sealed over the old bead. Can you fix it?
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?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What affects the cost of remedial sealant
Call for a quick quote. The main things that affect it are:
- How many rooms, windows or areas are involved
- The type of sealant required
- Any mould that needs treating
- The number and length of the joints
Leaving a failed joint usually makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
What we need to know
You don’t need to know the technical terms. Just tell us:
- Roughly how big the job is
- Whether it has been sealed before
- Photos by email, if that’s easy
- Any access issues, like height or stairs
We quote each job on its own. Simply ring 0345 464 0079 or drop us an email and describe the job.

How it works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on the amount of work. In Cranbrook, 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 look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
