Golders Green Remedial Sealant
Our applicators work in Golders Green on removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Gaps opening along the back of the worktop
- Leaks that keep coming back after resealing
- Black mould underneath the bead
Remedial sealant for homes and businesses in Golders Green
If a joint has been resealed and is leaking again, it’s worth a proper look. Send photos when you phone 0345 464 0079 or drop us an email. If you have leaks that keep coming back after resealing and over-sealed joints coming away, we can help, on mouldy bath & shower sealant, leaking tray & enclosure joints and failed movement joints alike.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In Golders Green, that’s a good reason to put tired sealant and grout right early.
A one-year guarantee comes with the work, just as it does everywhere we cover.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Quotes for remedial sealant in Golders Green
We quote each job individually. These are the things that affect it:
- The product the joint needs
- Working hours on commercial sites
- The amount of work
- Whether there’s mould to deal with
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What to tell us for a quote
To help us quote quickly, let us know:
- The rough size of the job
- A few photos by email, if you can
- The address or postcode of the job
- Any access issues, like height or stairs
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, phone 0345 464 0079 or send us an email.
What sealant work cannot fix
We’d rather tell you now than do work that won’t last, so these are the limits:
- Plumbing leaks behind walls or under trays
- Failed tanking or loose tiles behind the sealant
- A bath, tray or worktop that moves until it’s properly fixed
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before booking.
Joints and surfaces we work on
- Leaking tray & enclosure joints

Golders Green questions
Can you help a landlord with a rental near Cricklewood station?
Yes, we work for landlords and agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Can parking be tricky for a visit in Golders Green?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Can you take off two layers of silicone?
Yes. Both layers come out; over-sealing fails because silicone will not bond to silicone.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can failed expansion joints be resealed?
Yes. Backing sets the depth and stops the sealant sticking to the back.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Ask why a joint failed before redoing it
- Clean sealant with mild products only
- Keep an eye on the ceiling below the bathroom
- Deal with small splits early
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant cannot hold back a problem underneath.
Don’t keep resealing the same joint. Have someone find out why, or the next bead will go the same way.

Bathrooms and kitchens in Golders Green

Golders Green is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Managing a site like Rimon Jewish Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

Advice
What we are called out for in Golders Green
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, so it starts lifting sooner than it should.
It’s worth asking for a quote if you see:
- Over-sealed joints coming away
- Kitchen joints letting water behind the worktop
- Wide, uneven beads that look worse than the old ones
- Movement joints that have split or pulled away
For landlords with property near Cricklewood station, botched sealant from a previous quick fix is easier to strip out between tenants.
Questions to ask before booking
- What happens if they find a problem under the old sealant
- What guarantee comes with the work
- How the colour is chosen
- Whether all the old sealant comes out first
