Herne Remedial Sealant
Removing failed, mouldy or leaking sealant and putting it right in Herne, with a 12-month guarantee on every job. Ask us for a quote.
- Gaps opening along the back of the worktop
- Decorators’ caulk around a bath or shower
- Wide, uneven beads that look worse than the old ones
How it works
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. It generally takes a few hours for most joints, depending on how much old sealant has to come out. Parking around Herne is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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.
- 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.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises
- Clear the area around the work
Getting a quote

How we handle remedial sealant in Herne
Remedial jobs in Herne generally fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. Each is stripped back and done again properly. If you have torn expansion joints and mould trapped under a layer of silicone, we can put it right.
Even in a smaller place like Herne, bathrooms and kitchens see heavy daily use. Whether it’s a cottage bathroom or a newer en suite, the approach is the same: all the old material out, the joint cleaned and dried, then new sealant or grout.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Do you need remedial sealant in Herne?
How a joint is built matters as much as the product. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.
Most people get in touch after spotting one of these:
- Black mould underneath the bead
- A second bead peeling off the first
- Movement joints that have split or pulled away
- Products that weren’t meant for the joint
Rented homes near Herne Bay station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- How long the guarantee is
- What insurance they hold
- Is the old sealant removed completely?
When it isn’t the sealant
We will always be straight with you, so here’s what new sealant won’t do:
- A bath, tray or worktop that moves until it’s properly fixed
- A leaking trap, valve or supply pipe
- A cracked shower tray or bath (that needs repair or replacing)
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before you book.

Herne: your questions answered
Do you cover Herne for remedial sealant?
Yes. We work across London and the South East, and Herne is part of that. You can call 0345 464 0079 or email us and tell us what needs doing.
Will you come out to Herne?
Yes, Herne is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What if the leak isn’t the sealant?
That is why we look for the cause first. If we find the leak is elsewhere, we tell you before going further.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you work for landlords and businesses?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Herne.
My shower still leaks after a reseal. Can you sort it?
Yes. There’s usually a reason: sealant over sealant, movement or another leak, so we find that first.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Aftercare tips
To keep the joints looking good and working properly:
- Get the cause of a repeat leak found before resealing
- Do not point over movement joints
- Air the bathroom so the sealant can dry
- Always have old sealant cut out, not covered
Go easy on the new sealant: a mild cleaner and a soft cloth, with no blades or scourers.
If a joint has failed more than once, stop resealing it. Have someone find out why, otherwise the next attempt will fail too.

DIY sealant or a professional job?
What a professional job adds is preparation and the right 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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Remedial sealant in Herne: local notes
Herne is within about 2 miles of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
Schools such as Herne Church of England Infant School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. In the older streets around Church of St Martin, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Joints filled with mortar, grout or rigid filler can’t move. Where it can be raked out, we replace it with flexible sealant.
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. We check both before we reseal.
