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. We remove the failed sealant, fit backing and reseal.
Mouldy bath & shower sealant
Black mould inside the bead won’t scrub out. The sealant is cut out completely, the joint treated with a mould remover and dried before anti-fungal sanitary silicone goes in.
Remedial sealant for homes and businesses in Wealdstone
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. If you have dark patches showing through the sealant and caulk or the wrong sealant used in a wet area, we can help, whatever the surface.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in Wealdstone, getting the joints right keeps water where it belongs and the room looking clean.
All our work is covered by our one-year guarantee, wherever you are in Greater London.

Looking after it afterwards
To keep the joints looking good and working properly:
- Always have old sealant cut out, not covered
- Keep movement joints clear of mortar and paint
- Use a soft cloth, not a scourer, on silicone
- Report a tray that rocks or a worktop that lifts
Give the new sealant its full cure time: normally around 24 hours, or as long as we advise.
Don’t keep resealing the same joint. Get the cause found first, or the next bead will go the same way.
Bathrooms and kitchens in Wealdstone
London has hard water, which leaves limescale on sealant, grout and taps. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early.
For an older house near a landmark such as Holy Trinity Church, walls and floors in older homes can move, and sealant and grout show it first. For landlords with property near Harrow & Wealdstone station, botched sealant from a previous quick fix is easier to strip out between tenants. For site and facilities teams at buildings such as Marlborough Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What affects the cost of remedial sealant
There’s no set price list, because no two jobs are the same. The quote depends on:
- How much old sealant there is and how hard it is to remove
- Access and height
- Working hours on commercial sites
- The size of the job
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
Helping us quote
Before you ask for a quote, have a think about:
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- What’s wrong with the joints now
- Whether it has been sealed before

Why it’s worth doing now in Wealdstone
Adding more sealant is the usual quick fix, and it rarely works. It cannot bond to what’s underneath, leaving the leak in place and one more layer to cut out later. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Wealdstone, the repair is bigger than the sealant job would have been.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What happens on the day
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours for most joints, depending on how much old sealant has to come out in most cases. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Wealdstone. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
How to prepare

Advice
FAQs for Wealdstone
Is parking an issue for remedial sealant in Wealdstone?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
I live in a flat in Wealdstone. Can a failed seal leak into the flat below?
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.
How long does remedial resealing take?
That depends on how many layers there are and how many joints. We will tell you before any work starts.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. First we check whether the leak is the sealant at all, then strip and reseal the joints.
Can you remove old sealant without damaging the bath?
Yes. Careful removal is most of a remedial job, particularly on softer surfaces like acrylic.
What should I tell you?
Let us know what needs doing and where, plus pictures if you have them. If we need more, we’ll ask.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.

What else we do in Wealdstone
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
