About bathroom resealing in SE21
A fresh bead of silicone changes how a bathroom looks more than most people expect. Mouldy silicone makes even a new bathroom look neglected, and a neat new joint puts that right in a short visit. It also seals the gaps that let water behind the bath. We are often asked to deal with gaps where the bath or tray has moved and a reseal done over the top of the old bead, across shower trays & enclosures, baths and kitchen worktops & upstands.
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a couple of hours for a single bath or shower.
- First, each joint is checked for movement and signs of water.
- The old silicone is cut out completely, along with the film it leaves on the tiles.
- The joint is cleaned, degreased and treated for mould.
- With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
- We tool the bead to a neat finish and give you the cure time, generally around 24 hours.
What affects the price in SE21
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Bathroom resealing across SE21: local notes
Homes across SE21 range from older properties to new builds, and in places like West Norwood, Upper Norwood and Norwood New Town there’s plenty of rented property too. Bathroom resealing keeps bathrooms and kitchens watertight and looking cared for.
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings. Whatever the job in SE21, surfaces are cleaned back properly before new sealant goes in.
West Dulwich: West Dulwich is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Rented homes near Sydenham Hill station change hands often, and a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.
What affects the cost of bathroom resealing
The quote reflects the job in front of us. We take into account:
- The old material and how stubborn it is
- The product the joint needs
- How many areas need sealing
- When we can work, for business premises
Doing several joints on one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.
Helping us quote
When you call or email, it’s useful to know:
- Where the property is
- Access, such as stairs, a lift or height
- A few photos by email, if you can
- The type of property
For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we will explain what’s involved.
Landlords, agents and businesses in SE21
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Different surfaces, different methods
Shower trays & enclosures
A tray that rocks will split any sealant. We check for movement before we reseal, and if the tray needs refixing, we’ll say so.
Sinks & splashbacks
Around the sink, we use a product suited to kitchens, and a food-safe product where it’s needed. The bead is finished smooth so it wipes clean.
When something else is needed
Before booking, it’s worth knowing the limits too:
- Water coming from the plumbing rather than the joint
- A cracked shower tray or bath (that needs repair or replacement)
- Water getting in through the grout rather than the sealant
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Your questions about bathroom resealing in SE21
How long before the new sealant can get wet?
Usually after around 24 hours. We’ll tell you the cure time for the product we used.
Can landlords and businesses book you?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels across Greater London.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
What does bathroom resealing cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can you reseal around my kitchen sink and worktop?
Yes. Worktops, sinks and splashbacks are all part of the job, in a kitchen-suitable sealant, matched to the worktop where it’s on show.
