About our bathroom resealing in Feltham
Sealant that is mouldy, cracked or peeling is worth sorting before it lets water through. A photo of the joints helps when you phone 0345 464 0079 or drop us an email, and you will get a clear quote before any work starts. We are often asked to deal with lumpy, uneven sealant from a DIY attempt and a joint torn by a bath that flexes, across sinks & splashbacks, kitchen worktops & upstands and baths.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in Feltham, getting the joints right keeps water where it belongs and the room looking clean.
A one-year guarantee comes as standard, so you are covered after we have gone.

What affects the cost of bathroom resealing
For a quick quote, just ask. What matters most is:
- Which sealant suits the joint
- The size of the job
- When we can work, for business premises
- Mould in or behind the old joints
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
What we need to know
When you contact us, these details help:
- Pictures of the joints, sent by email
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
- The rough size of the job
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
Different surfaces, different methods
Wet rooms
A wet room floor and its walls can move independently, so the internal corners need silicone rather than grout. Where grout in a corner has cracked, we can replace it with sealant.
Sinks & splashbacks
Around the sink, we use a product suited to kitchens, including a food-safe sealant where that is needed. The bead is finished smooth so it wipes clean.
Leave it or put it right?
Fresh sealant smartens a bathroom or kitchen with very little disruption, which matters if you’re letting a property or selling it. Lumpy sealant with smears on the tiles has the opposite effect. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Feltham: your questions answered
Can parking be tricky for a visit in Feltham?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Can you help a landlord with a rental near Feltham station?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
How long does a bath or shower reseal take?
It takes two to three hours for a typical bath, depending on how much old sealant there is. You’ll know how long to expect before we start.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Feltham and the rest of Greater London, along with the rest of our area.
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
What happens on the day
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes around two hours for one bath or shower, longer for a whole bathroom. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- 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.
- We tool the bead to a neat finish and give you the cure time, normally around 24 hours.

Advice
When to call us in Feltham
Silicone does not last for ever. Daily water, heat and cleaning products slowly wear it down, and how long it lasts comes down to use, cleaning and ventilation.
If you can see any of these, it’s time to have the joints looked at:
- Lumpy, uneven sealant from a DIY attempt
- Failed sealant on the screen profile
- Splits where the tray meets the wall
- Sealant that has split, shrunk or peeled away
If you let a flat or house near Feltham station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.

Bathrooms and kitchens in Feltham
London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early.
If you look after a building such as St Lawrence Catholic Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. As a London address, Feltham can be tricky for parking: let us know about parking bays, permits or a driveway.
