- Repeat leaks from the same joint
- Movement joints that have split or pulled away
Remedial sealant in Hackney Marshes, done properly
Some sealant jobs are not a simple reseal, because someone has already had a go. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out before the joint can be done properly. If you have movement joints that have split or pulled away and mould trapped under a layer of silicone, we can help, whatever the surface.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Hackney Marshes, 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, in Hackney Marshes and everywhere else we cover.

What happens if it’s left?
Stripping out botched sealant adds time to a reseal, but not by much: it takes a few hours, depending on how many layers have to come out. It’s far less disruption than resealing the same joint again and again. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Hackney Marshes, the repair is bigger than the sealant job would have been.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Quotes for remedial sealant in Hackney Marshes
Every job gets its own quote. These are the things that affect it:
- The type of sealant required
- Any working-time requirements on site
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us and we will talk you through it.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
- How we’d reach the joints
- Any previous sealing or DIY work
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved.
Do you need remedial sealant in Hackney Marshes?
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
Look out for any of the following:
- A second bead peeling off the first
- Torn expansion joints
- Sealant that came away because the surface wasn’t prepared
- Black mould underneath the bead
If you live in an older home near The Risen Christ and All Souls, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
What to look for in a quote
- Is VAT in the price?
- Whether they’re fully insured
- How long to leave it before use
- How the surfaces are prepared before sealing
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Never seal over old silicone
- Do not wait for a small gap to become a leak
- Keep the room well ventilated
- Find out why the sealant failed first
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
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.
Hackney Marshes questions
Do you work for hotels and guest houses in Hackney Marshes?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Can worn sealant in a flat in Hackney Marshes cause a leak downstairs?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that’s down. A proper reseal before the leak starts is the easy fix.
What if the leak is not the sealant?
We check for that before we reseal. If we find the leak is elsewhere, we tell you before going further.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
What does remedial sealant cost?
Size, access and the old material all affect the cost. Call for a quick quote.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
How long will it take to strip and reseal the joint?
That depends on how many layers there are and how many joints. We’ll tell you before any work starts.
Honest limits
To be straight with you, there are a few things sealant won’t fix:
- Older mastics that may need an asbestos check before removal
- A bath, tray or worktop that moves until it’s properly fixed
- Water damage behind tiles that needs a tiler
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.
Joints and surfaces we work on

Remedial sealant around Hackney Marshes
London has hard water, which leaves limescale on sealant, grout and taps. In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early.
Schools such as Kingsmead 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.

How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes a few hours, depending on how many layers have to come out, depending on how much there is to do. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We start by checking the joint for movement, leaks and the reason it failed.
- All the old sealant comes out, including any layers underneath.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Keep children and pets away from the work area
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height

Advice
Different surfaces, different methods
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated.
Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, matched to the frame colour.
