Remedial Sealant in Chase Cross
Our applicators work in Chase Cross on removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- A shower that leaks however often it’s resealed
- Wide, uneven beads that look worse than the old ones
- Sealant that came away because the surface wasn’t prepared
Remedial sealant in Chase Cross, done properly
A joint that keeps failing usually has a reason. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. Finding that cause comes before any new sealant. If you have leaks that keep coming back after resealing and kitchen joints letting water behind the worktop, we can help, whatever the surface. Whether you’re looking for a local mastic man, a silicone specialist or a sealant contractor in Chase Cross, Mr Mastic can help.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest.
You’re covered for a year from the day we finish. If anything isn’t right with it, ring 07833 053749 or drop us an email.

For landlords and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Can I do it myself?
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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
When to call us in Chase Cross
Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, and tears at the first real movement. Backing sets the depth and stops that.
Look out for any of the following:
- Beads that never stuck properly
- Movement joints that have split or pulled away
- A shower that leaks however often it’s resealed
- Caulk or the wrong sealant used in a wet area
For landlords with property near Gidea Park station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

How it works
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a few hours, depending on how many layers have to come out for a typical job. For a job in Chase Cross, 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.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in

Leave it or put it right?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

What we can’t put right
Sealant is not the answer to every problem, and we’ll tell you before we start. It won’t solve:
- Water damage behind tiles that needs a tiler
- Movement from fittings that aren’t supported
- Plumbing leaks behind walls or under trays
Not sure which it is? You can phone 07833 053749 or drop us an email and we’ll tell you honestly.
Joints and surfaces we work on
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Failed movement joints
- Leaking tray & enclosure joints
- Expansion joints
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Use a soft cloth, not a scourer, on silicone
- Check ceilings under showers for marks
- Find out why the sealant failed first
- Air the bathroom so the sealant can dry
Where we’ve pointed out another fault, have it put right, or the new joint may fail again.
A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into whatever is behind or below. Early action keeps it to a sealant job.
Bathrooms and kitchens in Chase Cross
London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. 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.
If you live in an older home near St James, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Chase Cross is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Chase Cross questions
I live in a flat in Chase Cross. Can a failed seal leak into the flat below?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Can parking be tricky for a visit in Chase Cross?
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.
How long will it take to strip and reseal the joint?
Allow a few hours, depending on how many layers have to come out. You’ll know the timing when we quote.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Are you fully insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
