What we need to know
Before you ask for a quote, have a think about:
- How we’d reach the joints
- What’s wrong with the joints now
- The address or postcode of the job
- Any previous sealing or DIY work
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, phone 0345 464 0079 or drop us an email.
Remedial sealant in Fitzrovia, done properly
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. Common call-outs are for black mould underneath the bead and kitchen joints letting water behind the worktop, on botched or over-sealed joints, leaking tray & enclosure joints and mouldy bath & shower sealant.
London homes include a lot of flats, conversions and mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In Fitzrovia, that is a good reason to put tired sealant and grout right early.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What else we do in Fitzrovia
What happens if it’s left?
A failed seal rarely means a new bathroom. When the fittings are sound, stripping and resealing the joints is often enough. Where something else has failed, you will hear it from us. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What you get with us
- Homes, businesses and hotels
- Old sealant always removed completely
- An ARBOMaster approved applicator
- Anti-fungal sanitary silicone in wet areas

Your questions about remedial sealant in Fitzrovia
Do you take on hotel work around Fitzrovia?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
I live in a flat in Fitzrovia. 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.
Can old silicone be taken off without scratching the tiles?
Yes. We cut and lift the old sealant with tools suited to the surface, then clean off the residue. Any existing damage is pointed out before any work starts.
Can you reseal a split movement joint?
Yes. Backing sets the depth and stops the sealant sticking to the back, which lets it stretch.
Are you insured?
Yes. We’re fully insured.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Do you offer different sealant colours?
Normally, yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
Is remedial work guaranteed?
Yes. Our one-year guarantee covers the work, and we are ARBOMaster approved.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Clean sealant with mild products only
- Keep the room well ventilated
- Do not wait for a small gap to become a leak
- Have loose fittings fixed before resealing
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
When to call us in Fitzrovia
Using the wrong product is a common cause: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. None of them last.
It’s worth asking for a quote if you see:
- A shower that leaks however often it’s resealed
- Gaps opening along the back of the worktop
- Sealant peeling off a dusty or damp surface
- Smears and lumps from a botched reseal
As a London address, Fitzrovia can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Remedial sealant around Fitzrovia
Fitzrovia has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room. London has hard water, so limescale builds up on sealant, grout and fittings.
In the older streets around Whitefield's Tabernacle, walls and floors in older homes can move, and sealant and grout show it first. Managing a site like All Souls CofE Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

Honest limits
We’d rather tell you now than do work that will not last, so these are the limits:
- Plumbing leaks behind walls or under trays
- A tray or worktop that needs refixing first
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.
What we seal
- Botched or over-sealed joints
- Failed movement joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Expansion joints
- Leaking tray & enclosure joints
What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for most joints, depending on how much old sealant has to come out. 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.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children

Advice
Can I do it myself?
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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
