Eel Pie Island Remedial Sealant
Removing failed, mouldy or leaking sealant and putting it right for homes and businesses in Eel Pie Island and across Greater London. Fully insured, ARBOMaster approved and guaranteed for a year.
- Mould trapped under a layer of silicone
- Beads that never stuck properly
- Movement joints that have split or pulled away
How we handle remedial sealant in Eel Pie Island
If a joint has been resealed and is leaking again, it’s worth a proper look. It helps to have pictures when you ring 0345 464 0079 or drop us an email, and say how long ago it was last done. If you have beads that never stuck properly and floor or wall movement joints that have failed, we can put it right, on botched or over-sealed joints, shrunken worktop sealant and expansion joints alike.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Eel Pie Island, remedial sealant is as much about a room looking cared for as about keeping water out.
All of our work is guaranteed for twelve months.

- Plumbing leaks behind walls or under trays
- Failed tanking or loose tiles behind the sealant
- Sealant in an older building that needs testing for asbestos first
If in doubt, phone 0345 464 0079 or email us and we will say what we think before you book.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours, depending on how many layers have to come out. In a London area like Eel Pie Island, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- 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.
- The joint is tooled and you are told about anything else we found.
Preparing for the visit
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work

FAQs for Eel Pie Island
Could a tired shower seal in my Eel Pie Island flat affect the neighbours below?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that is down. Cutting out the old sealant and laying a new bead early stops it getting that far.
Can you help a landlord with a rental near Twickenham station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Do you work in Eel Pie Island?
Yes. We work in Eel Pie Island. For a quote, phone 0345 464 0079 or drop us an email.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
What if the leak isn’t the sealant?
That’s why we look for the cause first. If we find the leak is elsewhere, we tell you before going further.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
When to call us in Eel Pie Island
Water from somewhere else can ruin a good seal. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
Common reasons people contact us include:
- Smears and lumps from a botched reseal
- A second bead peeling off the first
- Sealant peeling off a dusty or damp surface
- Worktop sealant that has shrunk and split
Eel Pie Island is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

How we quote for remedial sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether the work is at height
- The product the joint needs
- Any working-time requirements on site
- Mould in or behind the old joints
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
When you call or email, it’s useful to know:
- Where the job is, and your postcode
- Photos by email, if that is easy
- If someone has resealed it before
- How many joints, rooms or windows are involved
Every job is quoted individually, so the first step is telling us about yours. Just ring 0345 464 0079 or drop us an email with the details and send photos if you have them.
Why it’s worth doing now in Eel Pie Island
Adding more sealant is the usual quick fix, and it rarely works. It cannot bond to what’s underneath, leaving the leak in place and one more layer to cut out later. In a flat in Eel Pie Island, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and send you a clear quote before any work starts.
Why choose Mr Mastic in Eel Pie Island
- White, clear, grey or coloured to suit, where the product allows
- Sanitary silicone with an anti-fungal additive in wet areas
- Experience in homes, commercial sites and hotels
- Any old sealant cut out fully, not covered over

For landlords with property near Twickenham station, botched sealant from a previous quick fix is easier to strip out between tenants. Managing a site like St Mary's Church of England Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Different surfaces, different methods
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so cleaning takes longer than in a bathroom before resealing.
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, including the smears and film on surrounding tiles. New sealant needs a fully clean surface.
