Remedial sealant in Anerley, done properly
Movement and expansion joints fail when the sealant can’t stretch. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. If you have torn expansion joints and black mould underneath the bead, we can help, on leaking tray & enclosure joints, shrunken worktop sealant and botched or over-sealed joints alike.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Anerley are no different.
Whatever the size of the job, it’s backed by our one-year guarantee.

Anerley questions
Is parking an issue for remedial sealant in Anerley?
Parking in Anerley, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you take on hotel work around Anerley?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we are using and why.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
How long will it take to strip and reseal the joint?
A little longer than a standard reseal. For most joints, it’s a few hours.
What happens if the problem is the tray or the plumbing?
You’ll hear it from us. If it’s a cracked tray, a failed valve or a leaking waste, resealing will not fix it, and we will not reseal for the sake of it.
What we cannot put right
We’ll always be straight with you, so here’s what sealant can’t fix:
- Older mastics that may need an asbestos check before removal
- A tray or bath that’s cracked
- A leaking trap, valve or supply pipe
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.
Joints and surfaces we work on
- Failed movement joints
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Expansion joints
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Quotes for remedial sealant in Anerley
We quote each job individually. This is what makes a difference:

- The size of the job
- The old material and how stubborn it is
- Access and height
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- If someone has resealed it before
- Access, such as stairs, a lift or height
- The type of property
- What the problem is, such as mould, gaps, leaks or cracking

For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll give you a quote.

What else we do in Anerley
How it works
On the day, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. In Anerley, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Run the fan after every shower
- Find out why the sealant failed first
- Don’t wait for a small gap to become a leak
- Don’t point over movement joints
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. Should anything change, ring 0345 464 0079 or drop us an email.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.
Do you need remedial sealant in Anerley?
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
If you can see any of these, it’s time to have the joints looked at:
- A shower that leaks however often it’s resealed
- Mould trapped under a layer of silicone
- Products that weren’t meant for the joint
- Worktop sealant that has shrunk and split
Schools such as James Dixon Primary School are buildings too, and 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.

Anerley homes and their sealant
London’s water is hard, so limescale builds up on sealant, grout and fittings. There are hotels and other places to stay in and around Anerley. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
In the older streets around St Paul's, walls and floors in older homes can move, and sealant and grout show it first. As a London address, Anerley can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
