How the job changes by surface
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, including the screen profile and tray edges.
Movement & expansion joints
Joints filled with mortar, grout or rigid filler cannot move. We rake that out where it can be removed and seal with a flexible product.
Remedial sealant in Cannon Hill, done properly
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. Only then can new sealant bond. If you have products that weren’t meant for the joint and movement joints that have split or pulled away, we can help, whatever the surface.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Cannon Hill are no different.
Every job is covered by our one-year guarantee.

Landlords, agents and businesses in Cannon Hill
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
We also work for property managers and facilities teams. Several sites can go on one quote.
How we quote for remedial sealant
We quote each job individually. These are the things that affect it:
- The type of sealant required
- The old material and how stubborn it is
- When we can work, for business premises
- Any mould that needs treating
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email.
Asking for a quote
Before you ask for a quote, have a think about:
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
- Where the property is
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand, and we’ll take it from there.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- A bath, tray or worktop that moves until it’s properly fixed
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Sealant in an older building that needs testing for asbestos first
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
Where we work in Cannon Hill

What remedial sealant looks like in Cannon Hill
London’s water is hard, which leaves limescale on sealant, grout and taps, 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.
Schools such as Hillcross 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. If you let a flat or house near South Merton station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Your questions about remedial sealant in Cannon Hill
Do you work for landlords with property near South Merton station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Can parking be tricky for a visit in Cannon Hill?
Parking in Cannon Hill, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
What does remedial sealant cost?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or send us an email and tell us what needs doing and where.
Can you strip sealant from an acrylic tray safely?
Yes. Residue is removed with a product suited to the surface rather than scraped hard, so the new sealant bonds cleanly.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Does remedial work come with a guarantee?
Yes. Every job comes with our 12-month guarantee.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
What if the leak is not the sealant?
In that case, we tell you what we’ve found. A plumber or fitter may be needed.
What we’re called out for in Cannon Hill
Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes split any bead that is too stiff or too thin.
These are the problems we are asked about most:
- Torn expansion joints
- Smears and lumps from a botched reseal
- Sealant peeling off a dusty or damp surface
- Kitchen joints letting water behind the worktop
Cannon Hill is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
What to look for in a quote
- What insurance they hold
- What product goes in the joint
- The length of the guarantee
- What the quote includes, VAT included or not
What happens if it’s left?
A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Cannon Hill.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

How it works
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes a few hours, depending on how many layers have to come out, depending on the amount of work. In Cannon Hill, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property
- Keep children and pets away from the work area
