Remedial sealant & repairs in Mayfair, Greater London
Remedial sealant across Mayfair and nearby, with old sealant always removed completely.
- Sealant that came away because the surface wasn’t prepared
- A second bead peeling off the first
- Dark patches showing through the sealant
How to look after the new joints
Looking after new joints is easy:
- Never seal over old silicone
- Check trays and worktops do not move
- Act on a lifting corner straight away
- Keep movement joints clear of mortar and paint
Where we have pointed out another fault, have it put right, or the new joint may fail again.
Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Each one is worth getting looked at.
Remedial sealant in Mayfair, done properly
A joint that keeps failing normally has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. Finding that cause comes before any new sealant. If you’re dealing with sealant that came away because the surface wasn’t prepared and caulk or the wrong sealant used in a wet area, we can put it right, on botched or over-sealed joints, shrunken worktop sealant and leaking tray & enclosure joints alike.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Mayfair more than a cosmetic job.
Every job is covered by a 12-month guarantee, wherever you are in Greater London.

What affects the quote in Mayfair
We quote each job individually. This is what makes a difference:
- The number and length of the joints
- Whether the work is at height
- Mould in or behind the old joints
- Any working-time requirements on site
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
Asking for a quote
To make quoting easier, let us know:
- Roughly how big the job is
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we will take it from there.
What sealant work can’t fix
We will always be straight with you, so here’s what sealant can’t fix:
- Sealant in an older building that needs testing for asbestos first
- Movement from fittings that aren’t supported
- Failed tanking or loose tiles behind the sealant
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before booking.

What the job involves on each surface
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed.
Windows & doors
Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.
Leave it or put it right?
A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Mayfair.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
What you get with us
- Sealant colour chosen to suit
- Arbo and Everbuild products
- Old sealant always removed completely
- We leave the area clean and tidy
Remedial sealant around Mayfair
There are hotels and other places to stay in and around Mayfair. Hotel bathrooms are part of our work as well as homes, and can be done room by room. 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.
As a London address, Mayfair can be tricky for parking: let us know about parking bays, permits or a driveway. Managing a site like LITE Regal International School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you let a flat or house near Bond Street station, a joint that keeps failing is best fixed properly while the property is empty.

Questions from Mayfair
I let a flat near Bond Street station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Do you take on hotel work around Mayfair?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Do you cover Mayfair?
Yes. We cover Mayfair, as part of our work across South East England, London and Scotland. For a quote, ring 0345 464 0079 or drop us an email.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
How it works
We keep the work tidy and contained to the area we are working on. Expect the work to take a few hours for most joints, depending on how much old sealant has to come out, and we explain the cure time before we leave. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Mayfair. A visitor permit or a nearby bay makes the visit run more smoothly.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you are ready, phone 0345 464 0079 or send us an email.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
