Remedial sealant in Ley Green, done properly
If a joint fails again and again, something is causing it. A tray that moves, a worktop that isn’t fixed, the wrong sealant or water getting in elsewhere will defeat even a perfect bead. We look for the cause before we reseal. We work on shrunken worktop sealant, mouldy bath & shower sealant and botched or over-sealed joints, and people most often call us about products that weren’t meant for the joint and dark patches showing through the sealant.
Homes around Ley Green are mostly houses and cottages rather than flats. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
Every job comes with a 12-month guarantee.

Leave it or put it right?
DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. Where a wall is exposed, as many are in small places like Ley Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or email us.

Also in Ley Green
Different surfaces, different methods
Movement & expansion joints
Joints filled with mortar, grout or rigid filler cannot move. Where it can be raked out, we replace it with flexible sealant.
Mouldy bath & shower sealant
Mould that has grown into silicone doesn’t clean out for good. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.
What we’re called out for in Ley Green
A lot of failed joints have been sealed over rather than replaced. Silicone doesn’t bond to silicone, so the new layer peels, and damp and mould settle between them.
Any of these means the joints need attention:
- Movement joints that have split or pulled away
- Mould trapped under a layer of silicone
- Wide, uneven beads that look worse than the old ones
- Kitchen joints letting water behind the worktop
If you look after a building such as Preston Primary School, 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.

FAQs for Ley Green
I let a flat near Hitchin station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you cover Ley Green for remedial sealant?
Yes. Our work covers London and the South East, and Ley Green is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Can old silicone be taken off without scratching the tiles?
Yes, with care. The old bead is cut and lifted with tools that suit the surface, then clean off the residue. Any existing damage is pointed out before we start.
Are you fully insured?
Yes. We are fully insured for every job we do.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
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.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is remedial work guaranteed?
Yes. You get our 12-month guarantee, and we’re ARBOMaster approved.
How the visit works
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a typical bath or shower, longer where several layers have been applied for a typical job. Somewhere like Ley Green needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Before we arrive
- Clear items away from the joints we are working on
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can

What we cannot put right
Sealant is not the answer to every problem, and we’ll tell you before we start. Sealant will not put right:
- Sealant in an older building that needs testing for asbestos first
- Plumbing leaks behind walls or under trays
- Cracks in the fitting rather than the joint
If in doubt, call 0345 464 0079 or email us and we will say what we think.
Where we work in Ley Green
- Leaking tray & enclosure joints
- Expansion joints
- Botched or over-sealed joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Failed movement joints
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Bathrooms and kitchens in Ley Green
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
If you let a flat or house near Hitchin station, a joint that keeps failing is best fixed properly while the property is empty. If you live in an older home near Church of St Mary, older homes can move a little, which is hard on rigid grout and tired sealant.
