Lower Morden Remedial Sealant
Removing failed, mouldy or leaking sealant and putting it right for homeowners, landlords and businesses in Lower Morden. Fully insured, ARBOMaster approved and guaranteed for a year.
- Thick, messy sealant smeared over tiles
- Kitchen joints letting water behind the worktop
- Over-sealed joints coming away
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Never seal over old silicone
- Never fill a movement joint with mortar or grout
- Deal with small splits early
- Use a soft cloth, not a scourer, on silicone
Watch the joint over the first few weeks, especially if movement was the problem. If anything changes, just call 0345 464 0079 or email us.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
Remedial sealant for homes and businesses in Lower Morden
A joint that keeps failing normally has a reason. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. We look for the cause before we reseal. If you’re dealing with sealant peeling off a dusty or damp surface and torn expansion joints, we can help, whatever the surface.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. A compact bathroom that steams up every day is hard on silicone and grout, and homes in Lower Morden are no different.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What else we do in Lower Morden
What we do, step by step
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for most joints, depending on how much old sealant has to come out, including the tidy-up. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Lower Morden. 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.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
- Mention any leaks or damp you’ve noticed
Ask for a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
Advice
What affects the cost of remedial sealant
There’s no set price list, because jobs vary so much. The quote depends on:
- Mould in or behind the old joints
- Any working-time requirements on site
- The old material and how stubborn it is
- The number of rooms or windows
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Where the job is, and your postcode
- Whether it’s a home or a business
- The problem you’ve noticed
- Access, such as stairs, a lift or height
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you are ready, phone 0345 464 0079 or drop us an email.
When it is not the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Movement from fittings that aren’t supported
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Failed tanking or loose tiles behind the sealant
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

Lower Morden: your questions answered
Can parking be tricky for a visit in Lower Morden?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
I live in a flat in Lower Morden. Can a failed seal leak into the flat below?
Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Do you come to Lower Morden?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
How do I get a quote for remedial sealant in Lower Morden?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or email us.
Do you need remedial sealant in Lower Morden?
A lot of failed joints have been sealed over rather than replaced. New silicone can’t stick to the old bead, so the top layer lifts and water and mould collect between the two.
It’s worth asking for a quote if you see:
- Thick, messy sealant smeared over tiles
- A shower that leaks however often it’s resealed
- Caulk or the wrong sealant used in a wet area
- Kitchen joints letting water behind the worktop
Lower Morden is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
Before booking anyone
- When the joint can take water or movement
- Whether the sealant suits the joint
- What insurance they hold
- How the joint is cleaned and prepared
DIY versus a professional finish
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, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
For landlords and businesses
We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Lower Morden homes and their sealant
In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early. London’s water is hard, which leaves limescale on sealant, grout and taps.
Rented homes near St Helier station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For site and facilities teams at buildings such as Aragon Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.
