Bathroom resealing for homes and businesses in Three Mills
Showers work their sealant harder than baths. Trays, enclosures, screen profiles and wet room floors all need a flexible, waterproof seal. They’re resealed with anti-fungal sanitary silicone, finished smooth so water drains away rather than collecting. We work on kitchen worktops & upstands, wet rooms and sinks & splashbacks, and the jobs we see most are lumpy, uneven sealant from a DIY attempt and two layers of silicone, both failing.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. In Three Mills, that is a good reason to put tired sealant and grout right early.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Three Mills homes and their sealant
Three Mills 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, which leaves limescale on sealant, grout and taps.
Rented homes near West Ham 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. Three Mills is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What happens if it’s left?
Sorting it now is quick: it takes a morning or an afternoon for most single baths and showers. Wait for a leak and you may be looking at panels off, drying out and redecorating too. Converted houses in London often have a bathroom above someone else’s living room, 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 we do, step by step
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a morning or an afternoon for most single baths and showers from start to finish. In Three Mills, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- 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.
- We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
- We clear away and tell you when it can get wet, generally after around 24 hours.
Getting ready for the visit
- Move anything stored near the joints
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks

Getting a quote is simple: tell us what needs doing and where. Photos by email help us understand the job, and we’ll take it from there.
Related advice
Can I do it myself?
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 fails, we can still redo it.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Damage behind the tiles that needs a tiler
- Failed grout lines across the wall
- Movement from a bath with loose feet or no proper support
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before you book.

How we quote for bathroom resealing
You will get a clear quote before any work starts. It’s based on:
- How much there is to do
- Any working-time requirements on site
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Whether it has been sealed before
- A few photos by email, if you can
- The address or postcode of the job
- Roughly how big the job is
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work.
When to call us in Three Mills
A bath shifts a little every time it’s filled and emptied. An acrylic bath flexes under load, and a tray that isn’t fully bedded can rock. That movement works at the bead until it splits or peels away.
If you can see any of these, it’s time to have the joints looked at:
- Lumpy, uneven sealant from a DIY attempt
- Water getting behind the kitchen upstand
- Damp behind the bath or under the tray
- Leaking joints on a shower screen
In the older streets around St Mary's Church, walls and floors in older homes can move, and sealant and grout show it first.
Questions to ask before booking
- What preparation is included
- Which colour the sealant will be
- The length of the guarantee
- How long to leave it before use
FAQs for Three Mills
Can parking be tricky for a visit in Three Mills?
Parking in Three Mills, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do you take on hotel work around Three Mills?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Can you just seal over the old silicone?
No, never. A bead laid over old silicone soon starts to come away. Every trace of the old bead is removed first.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.
