- Wide, uneven beads that look worse than the old ones
- Beads that never stuck properly
What we are called out for in White City
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
If you can see any of these, it’s time to have the joints looked at:
- Caulk or the wrong sealant used in a wet area
- Torn expansion joints
- Gaps opening along the back of the worktop
- Repeat leaks from the same joint
As a London address, White City can be tricky for parking: let us know about parking bays, permits or a driveway.
Before booking anyone
- Whether the sealant suits the joint
- What insurance they hold
- What preparation is included
- Whether they seal over old material or remove it
How we handle remedial sealant in White City
Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that’s what we find, we’ll tell you rather than reseal something that won’t fix it. If you’re dealing with over-sealed joints coming away and wide, uneven beads that look worse than the old ones, we can put it right, whatever the surface.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout, and homes in White City are no different.
All our work is covered by a 12-month guarantee, wherever you are in Greater London.

How the job changes by surface
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We work carefully to avoid adding to it, and tell you about any damage we find.
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing stops that, so the sealant grips the two sides only.
Bathrooms and kitchens in White City
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early. White City has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
If you let a flat or house near Shepherds Bush station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For an older house near a landmark such as St Michael and St George, walls and floors in older homes can move, and sealant and grout show it first.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Never seal over old silicone
- Report a tray that rocks or a worktop that lifts
- Find out why the sealant failed first
- Look for stains below bathrooms now and then
If the joint ever needs renewing, have it cut out, not sealed over. New silicone doesn’t bond to old.
Don’t keep resealing the same joint. Have someone find out why, otherwise the next attempt will fail too.
Work for landlords, hotels and businesses
We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.

Quotes for remedial sealant in White City
We do not publish a price list, because jobs vary so much. What we look at:
- The number and length of the joints
- How many areas need sealing
- Working hours on commercial sites
- The product the joint needs
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
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:
- Where the job is, and your postcode
- The rough size of the job
- Photos by email, if that’s easy
- What’s wrong with the joints now
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To arrange one, ring 0345 464 0079 or send us an email.
DIY sealant or a professional job?
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.
If you are set on DIY, put the effort into 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.
White City questions
Do you work for landlords with property near Shepherds Bush station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Can parking be tricky for a visit in White City?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
How much does remedial sealant cost in White City?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or drop us an email and let us know what needs doing and where.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. We will take all the sealant out, look for why it failed and reseal it properly.
Are you insured?
Yes. We are fully insured for domestic and commercial work.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Will there be a smell?
Possibly a little. It fades as the sealant cures.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes a few hours for a typical bath or shower, longer where several layers have been applied. For a job in White City, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We start by checking the joint for movement, leaks and the reason it failed.
- All the old sealant comes out, including any layers underneath.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- Finally we finish the joint and talk you through what we found.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before
