Blacklands Remedial Sealant

- Black mould underneath the bead
- Movement joints that have split or pulled away
- A shower that leaks however often it’s resealed
Why deal with it now?
Hidden water does the most damage: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. Around Blacklands, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Doing several joints on one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

Remedial sealant for homes and businesses in Blacklands
If a joint fails again and again, something is causing it. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. Finding that cause comes before any new sealant. We are often asked to deal with sealant peeling off a dusty or damp surface and a shower that leaks however often it’s resealed, across mouldy bath & shower sealant, leaking tray & enclosure joints and expansion joints.
Homes around Blacklands range from older cottages to more recent houses. Older homes can move a little with the seasons, which is hard on tired sealant and rigid grout.
Whatever the size of the job, you get the same one-year guarantee in Blacklands and across East Sussex.

Your questions about remedial sealant in Blacklands
Do you take on hotel work around Blacklands?
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.
Do you work for landlords with property near Ore station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Can failed expansion joints be resealed?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Are you insured?
Yes. Mr Mastic is fully insured.
When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.
What if resealing will not fix my leak?
In that case, we tell you what we’ve found. You may need a plumber or bathroom fitter.
What the job involves on each surface
Windows & doors
Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated.
The process
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on how much there is to do. In a smaller place like Blacklands, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We protect the surfaces around the joint.
- 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.
- We give you the cure time and explain what caused the failure.
How to prepare
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area
- Mention any tricky access
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Related advice
Looking after it afterwards
Aftercare is simple:
- Report a tray that rocks or a worktop that lifts
- Keep bleach and abrasives off the bead
- Run the fan after every shower
- Do not add new sealant on top of old
Where we’ve pointed out another fault, have it put right, or the new joint may fail again.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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, and the work is guaranteed for a year.

What remedial sealant looks like in Blacklands
Blacklands is close to 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. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you let a flat or house near Ore station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For site and facilities teams at buildings such as Ark Blacklands Primary Academy, 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. For an older house near a landmark such as Christ Church, older homes can move a little, which is hard on rigid grout and tired sealant.
