How we handle remedial sealant in Westminster
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, without scratching tiles, trays or frames. Only then can new sealant bond. We work on leaking tray & enclosure joints, expansion joints and shrunken worktop sealant, and common reasons people get in touch are torn expansion joints and caulk or the wrong sealant used in a wet area.
Hard London water leaves limescale on sealant, grout and taps alike. In Westminster, remedial sealant is as much about a room looking cared for as about keeping water out.
Your job is guaranteed for a year, as with all our work.

Bathrooms and kitchens in Westminster
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. 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.
If you look after a building such as Harris Westminster Sixth Form, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. For landlords with property near London Victoria station, a joint that keeps failing is best fixed properly while the property is empty. If you live in an older home near Christ Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Keep the room well ventilated
- Don’t wait for a small gap to become a leak
- Look for stains below bathrooms now and then
- Never fill a movement joint with mortar or grout
Watch the joint over the first few weeks, especially if movement was the problem. Should anything change, phone 0345 464 0079 or drop us an email.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
What we do, step by step
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes a few hours for most joints, depending on how much old sealant has to come out, depending on how much there is to do. In Westminster, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks

How we quote for remedial sealant
Jobs vary more than people expect. The main factors:
- The old material and how stubborn it is
- The type of sealant required
- The size of the job
- How easy the joints are to reach
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins, so you know where you stand.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Roughly how big the job is
- How we’d reach the joints
- Whether it’s a home or a business
- If someone has resealed it before

Leave it or put it right?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. 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. Putting it right early is much less trouble for homes in Westminster.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and give you a clear price before any work starts.
Why book with us
- White, clear, grey or coloured to suit, where the product allows
- Domestic, commercial and hotel work
- An ARBOMaster approved applicator
- Colour agreed with you before work begins

Your questions about remedial sealant in Westminster
Do you work in hotels near Westminster?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Can worn sealant in a flat in Westminster cause a leak downstairs?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that’s down. Cutting out the old sealant and laying a new bead early stops it getting that far.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
My shower still leaks after a reseal. Can you sort it?
Yes. First we check whether the leak is the sealant at all, then the joints are stripped and resealed.
Can you remove old sealant without damaging the bath?
Yes. Residue is removed with a product suited to the surface rather than scraped hard.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Can you reseal a split movement joint?
Yes. Where mortar or filler has been used instead of sealant, it’s removed where it can be, and reseal with a flexible product.
Different surfaces, different methods
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so cleaning takes longer than in a bathroom.
Windows & doors
A frame that keeps leaking may not be the mastic. We check the joint and tell you if it looks to be something else.
