About our bathroom resealing in Dulwich
A shower joint gets soaked every day. Trays, enclosures, screen profiles and wet room floors all need a flexible, waterproof seal. They’re resealed with anti-fungal sanitary silicone, tooled smooth so water runs off instead of sitting in a ridge. Common call-outs are for shrunken sealant along the back of a worktop and leaks into the floor or ceiling below, across kitchen worktops & upstands, wet rooms and basins & vanity units.
Hard London water leaves limescale on sealant, grout and taps alike. In Dulwich, bathroom resealing is as much about a room looking cared for as about keeping water out.
Whatever the size of the job, it’s backed by our one-year guarantee.

What affects the quote in Dulwich
Every job gets its own quote. These are the things that affect it:
- Access and height
- Any mould that needs treating
- How much there is to do
- How many rooms, windows or areas are involved
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
- Access, such as stairs, a lift or height
- Whether it’s a home or a business
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
Different surfaces, different methods
Sinks & splashbacks
The edge of an inset sink is a common place for water to get under the worktop. We reseal the visible edge of the sink where it has failed.
Baths
Acrylic baths flex the most, and even steel and cast iron baths settle slightly when full. Loading the bath with water before sealing allows for it.

How it works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen, depending on how much there is to do. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Dulwich. A visitor permit or a nearby bay makes the visit run more smoothly.
- Protection goes down around the bath, shower or worktop.
- We cut away the old sealant and clean off what’s left.
- Mould is treated, then the joint is left to dry thoroughly.
- Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Preparing for the visit
- Clear the area around the work
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Keep scourers and sharp tools away from the bead
- Look for lifting corners and small gaps now and then
- Dry the bead with a towel now and then
- Do not let bottles sit on the bead
Keep bottles and razors off the sealant line, because they trap water against the silicone. Squeegeeing the walls and tray after use keeps water from sitting on the joint.
Do not wait for a refit to deal with failed sealant. Sealant is a maintenance item, like the paint on a window frame, and replacing it when it fails protects the rest of the room.
Bathrooms and kitchens in Dulwich
Dulwich 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. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early.
In the older streets around Christ's Chapel of God's Gift, older homes can move a little, which is hard on rigid grout and tired sealant. Rented homes near West Dulwich station change hands often, and fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay. Schools such as St Anthony's Catholic Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Questions from Dulwich
Can worn sealant in a flat in Dulwich cause a leak downstairs?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
Do you take on hotel work around Dulwich?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
How long does it take to reseal a bath or shower?
It depends on how many joints there are and how much old sealant has to come out. Allow a couple of hours for a typical bath or shower.
Can new silicone go straight over the old?
No, never. Sealing over the top looks fine for a few weeks, then lifts. Every trace of the old bead is removed first.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
How long does the new silicone need before I use the shower?
We give you the cure time before we leave, and it’s generally around 24 hours. Using it sooner can damage the bead.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Why deal with it now?
Bleach and mould sprays may lighten black marks for a while, but mould that has grown into the sealant tends to return. Cutting it out and resealing with anti-fungal silicone is the fix that lasts. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
What you pay reflects the work, not guesswork. That is why we ask about the job first and send you a clear quote before work begins.

Can I do it myself?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
What we can’t put right
In fairness, there are a few things sealant will not fix:
- Cracked or missing grout between tiles (that is regrouting)
- Tiles that have come away from the wall
- A bath or tray that moves because it is not properly supported
