Our bathroom resealing service in KT3
Sealant is the soft line between a bath, shower or worktop and the wall. When it splits, shrinks or turns black, water gets behind it. Every trace of the old sealant is taken out and replaced with anti-fungal sanitary silicone. We work on basins & vanity units, baths and shower trays & enclosures, and people most often call us about black mould in the silicone that won’t clean off and sealant that has split, shrunk or peeled away.
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a morning or an afternoon for most single baths and showers.
- We look at every joint first and check for movement or leaks.
- The old silicone is cut out completely, along with the film it leaves on the tiles.
- Joints are degreased and any mould is treated.
- When the joint is dry, and a bath has been filled with water, the new silicone goes on.
- The bead is tooled smooth and you’re told the cure time, normally around 24 hours.
How we quote
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.

Local landmarks in New Malden
Locally, jobs take us to homes and businesses close to New Malden Baptist Church, The Glasshouse pub and Beverley Park, among other places. Also close by are Christ Church New Malden CofE Primary School (within half a mile north-east) and Holy Cross School (under half a mile south). There’s a railway station in New Malden itself: New Malden station. Well-known places in the area include Chessington Castle Hill (3.3 miles south) and Bentall Centre (1.9 miles west). Green spaces nearby include Rose Walk and Kingston Hill Road area.
Bathrooms and kitchens across KT3
In KT3, bathroom resealing takes in flats, houses, rentals and businesses, in New Malden, Norbiton and Tolworth and well beyond. Wherever the job is, all the old material comes out before anything new goes in.
From Victorian terraces to post-war new towns and modern estates, homes across the South East and London cover every era. Each needs the right sealant for its age and materials, wherever it is in KT3.
New Malden: Homes close to New Malden Baptist Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. Rented homes near New Malden station change hands often, and mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets.
Surface by surface
Shower trays & enclosures
Water often gets past the wall profile of a shower enclosure. We reseal it along with the base of the enclosure, following the enclosure maker’s guidance on which side to seal.
Basins & vanity units
Basins take less water than showers, but the joint behind them is splashed every day. Corners behind basins are where mould tends to start, and we treat it exactly as we would a bath.
Quotes for bathroom resealing in KT3
We quote each job individually. These are the things that affect it:
- The number of rooms or windows
- How easy the joints are to reach
- The product the joint needs
- The old material and how stubborn it is
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Helping us quote
To make quoting easier, let us know:
- Photos by email, if that is easy
- If someone has resealed it before
- How we’d reach the joints
- The rough size of the job
For a quote, ring 0345 464 0079 or email us and tell us where the job is and what the problem looks like. You’ll have a clear quote before any work starts.
Signs you need bathroom resealing
Black mould is behind a lot of resealing. Bathrooms without good ventilation give mould all the damp it needs, and once it has grown into the bead, cleaning rarely gets it out.
People normally contact us when they notice something like this:
- Lumpy, uneven sealant from a DIY attempt
- Gaps where the bath or tray has moved
- Water escaping at the shower enclosure
- A bead that has pulled away from the tiles
Landlords, agents and businesses in KT3
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Should I try it myself 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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
KT3: your questions answered
How long does the new silicone need before I use the shower?
After around 24 hours in most cases. We’ll tell you the cure time for the product we used.
Do you do kitchens as well as bathrooms?
Yes. Kitchen joints get extra degreasing before the new bead goes on, then a colour-matched bead is laid.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Can mouldy silicone be sorted out?
Yes, by replacing the sealant. Sprays can fade the marks, but cutting it out and resealing is what lasts. Airing the room well helps stop it returning.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover KT3 and the rest of Greater London, along with the rest of our area.
What colours of sealant can you use?
White and clear are the most common choices, but other colours can be used to suit tiles and worktops. Tell us what you’d like when you get in touch.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
