About our remedial sealant in Dagenham
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. Only then can new sealant bond. If you have dark patches showing through the sealant and thick, messy sealant smeared over tiles, we can help.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Dagenham are no different.
Each job carries a 12-month guarantee.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
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.
When it is not the sealant
Before you book, it’s worth knowing the limits:
- Sealant in an older building that needs testing for asbestos first
- A tray or worktop that needs refixing first
- Cracks in the fitting rather than the joint
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal
- Expansion joints
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Failed movement joints
- Shrunken worktop sealant
- Botched or over-sealed joints
Common problems we fix in Dagenham
All sealant wears out eventually. Over the years it shrinks, hardens and gets colonised by mould, faster where ventilation is poor. At that point it has to come out.
It’s worth asking for a quote if you see:
- Caulk or the wrong sealant used in a wet area
- Floor or wall movement joints that have failed
- Dark patches showing through the sealant
- A second bead peeling off the first
As a London address, Dagenham can be tricky for parking: let us know about parking bays, permits or a driveway.

What the job involves on each surface
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.
Mouldy bath & shower sealant
Mould that has grown into silicone doesn’t clean out for good. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.
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. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Dagenham, the repair is bigger than the sealant job would have been.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

Bathrooms and kitchens in Dagenham
London’s water is hard, 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.
If you live in an older home near St. Peter and St. Paul, walls and floors in older homes can move, and sealant and grout show it first. If you look after a building such as Village Infants' School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Common questions in Dagenham
Can you help a landlord with a rental near Dagenham Dock station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Could a tired shower seal in my Dagenham flat affect the neighbours 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. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you when we finish.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Is remedial work guaranteed?
Yes. Every job comes with our 12-month guarantee.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Can you fix a reseal that hasn’t worked?
Yes. Repeat leaks normally come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
For landlords and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.
The process
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours for a typical bath or shower, longer where several layers have been applied, including the tidy-up. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- 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.
Before we arrive
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property
