About our remedial sealant in Cockfosters
Remedial jobs in Cockfosters usually fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. Each is stripped back and done again properly. If you have worktop sealant that has shrunk and split and dark patches showing through the sealant, we can put it right, on expansion joints, leaking tray & enclosure joints and mouldy bath & shower sealant alike.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Cockfosters, remedial sealant is as much about a room looking cared for as about keeping water out.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What affects the cost of remedial sealant
We quote each job individually. This is what makes a difference:
- The number of rooms or windows
- The product the joint needs
- Any mould that needs treating
- The size of the job
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
Helping us quote
What to tell us when you ask for a quote:
- What’s wrong with the joints now
- If someone has resealed it before
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved
We quote each job on its own, so the first step is telling us about yours. Simply call 0345 464 0079 or drop us an email and describe the job, and photos are welcome.
Cockfosters questions
Could a tired shower seal in my Cockfosters flat affect the neighbours below?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
Do you take on hotel work around Cockfosters?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Do you fix expansion and movement joints?
Yes. Backing sets the depth and stops the sealant sticking to the back, which lets it stretch.
How long before the joint can be used?
It depends on the product and the conditions. We tell you how long to leave it before we go.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.

What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. For a job in Cockfosters, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First we find out how and where the joint has failed.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- 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
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Common problems we fix in Cockfosters
Joint depth matters. A bead bonded on three sides, or laid too thick, can’t flex, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.
People generally contact us after spotting something like this:
- Gaps opening along the back of the worktop
- Sealant applied over old sealant that has lifted
- Mould trapped under a layer of silicone
- A shower that leaks however often it’s resealed
As a London address, Cockfosters can be tricky for parking: let us know about parking bays, permits or a driveway.
Before booking anyone
- How the surfaces are prepared before sealing
- Whether VAT is included
- What the cure time is
- How much experience the applicator has
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Don’t point over movement joints
- Get the cause of a repeat leak found before resealing
- Have loose fittings fixed before resealing
- Check ceilings under showers for marks
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
How the job changes by surface
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing stops that, letting the sealant flex between the two faces.
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, which we will point out.
