Remedial sealant in Hackney Central
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. We work on mouldy bath & shower sealant, leaking tray & enclosure joints and failed movement joints, and people most often call us about worktop sealant that has shrunk and split and movement joints that have split or pulled away.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest.
Every job is covered by a 12-month guarantee.

Leave it or put it right?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. Converted houses in London often have a bathroom above someone else’s living room, 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 Hackney Central.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
Why us?
- Neat joints and a tidy finish
- Colour agreed with you before any work starts

Remedial sealant in Hackney Central: local notes
London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. 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.
Hackney Central is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you look after a building such as Gayhurst Community School, we reseal washrooms and kitchens in schools and businesses as well as homes. For an older house near a landmark such as Church of St Michael and All Angels, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

- Cracks in the fitting rather than the joint

Where we work in Hackney Central
- Botched or over-sealed joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Failed movement joints
- Expansion joints
- Leaking tray & enclosure joints
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Different surfaces, different methods
Mouldy bath & shower sealant
Black mould inside the bead won’t scrub out. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant will not fix it. We say so rather than reseal.
Your questions about remedial sealant in Hackney Central
Is parking a problem for a job in Hackney Central?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Do you work for hotels and guest houses in Hackney Central?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
What does remedial sealant cost?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or drop us an email with a short description of the job.
Do you cover Hackney Central?
Yes, we do. Hackney Central is part of the area we cover, and the service is the same as everywhere else.
Can you remove old sealant without damaging the bath?
Yes. We cut and lift the old sealant with tools suited to the surface, and the residue is cleaned away. Any existing damage is pointed out before work begins.
Where is Mr Mastic based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours, depending on how many layers have to come out, and the area is left clean. In Hackney Central, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints
