Bathroom & kitchen resealing in Coldharbour, Surrey
We cover Coldharbour for bath, shower, basin, wet room, worktop and sink resealing. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Splits where the tray meets the wall
- Smears of silicone across the tiles
- Water getting behind the kitchen upstand
What we do, step by step
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes around two hours for one bath or shower, longer for a whole bathroom, including the tidy-up. In a small place like Coldharbour, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We protect the area and cut out all of the old sealant.
- We clean and degrease the joint and treat any mould.
- Once it’s dry, any bath is filled so the bead is laid with it at its heaviest.
- A single bead of anti-fungal sanitary silicone is applied and tooled smooth.
- We clear away and tell you when it can get wet, normally after around 24 hours.
Before we arrive
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children

How we handle bathroom resealing in Coldharbour
Resealing is a small job that makes a big difference. Black, patchy sealant makes clean tiles look tired, and a neat new joint puts that right in a short visit. It also seals the gaps that let water behind the bath. Typical jobs include a joint torn by a bath that flexes and damp behind the bath or under the tray, on shower trays & enclosures, kitchen worktops & upstands and wet rooms.
Somewhere as small as Coldharbour, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
There’s a 12-month guarantee on every job, large or small.

Signs you need bathroom resealing in Coldharbour
The wrong product fails fast. Decorators’ caulk and all-purpose sealants are not made for constant wetting, so they stain, crack or go mouldy before long. A bathroom joint needs anti-fungal sanitary silicone.
People usually contact us after spotting one of these:
- Black spots spreading through the bead
- A reseal done over the top of the old bead
- Gaps where the bath or tray has moved
- Smears of silicone across the tiles
Rented homes near Holmwood 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.

What else we do in Coldharbour
Leave it or put it right?
Fresh sealant smartens a bathroom or kitchen with very little disruption, which helps when a home is being let or put on the market. Lumpy sealant with smears on the tiles has the opposite effect, and it’s harder to put right later. Older cottages and farmhouses around Coldharbour can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.
Why us?
- 12-month guarantee on every job
- We agree the colour with you first
- Tidy, careful work
- Colour picked to suit the job

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Bathroom resealing in Coldharbour: local notes
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around Christ Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Surface by surface
Sinks & splashbacks
Splashbacks in glass, tile or acrylic meet the worktop in a long joint. We renew it in clear, white or a matched colour.
Baths
Baths move more than any other fitting, so we fill it with water before sealing. That way the joint is laid with the bath at its heaviest and is not stretched when it’s used.
Common questions in Coldharbour
Can you do bathroom resealing in Coldharbour?
Yes, Coldharbour is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear price.
Is Coldharbour within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Do you do kitchens as well as bathrooms?
Yes. Where it’s needed by the sink, we use a food-safe sealant.
Is it OK to put new sealant on top of the old bead?
No. Fresh silicone cannot stick to the old bead, so it lifts and traps water and mould underneath. We always take the old sealant out completely.
How long does the new silicone need before I use the shower?
The surface skins over fairly quickly, but the bead needs longer to cure right through. Leave it around 24 hours before it gets wet, or as long as we advise for that product.
Landlord and commercial work in Coldharbour
If you manage several properties in or around Coldharbour, several properties can be quoted together. Send us the addresses and the work at each.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
When it is not the sealant
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Loose or hollow tiles, or failed tanking behind them
- Movement from a bath with loose feet or no proper support
- Cracked or missing grout between tiles (that is regrouting)
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
