About our remedial sealant in Blackgang
Movement and expansion joints fail when the sealant cannot stretch. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. If you have movement joints that have split or pulled away and sealant applied over old sealant that has lifted, we can help.
For a small place like Blackgang, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.
We stand behind the work with a 12-month guarantee.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Signs you need remedial sealant in Blackgang
All sealant wears out eventually. Over the years it shrinks, hardens and gets colonised by mould, especially in damp, poorly aired rooms. At that point it has to come out.
Keep an eye out for these signs:
- Torn expansion joints
- Black mould underneath the bead
- Repeat leaks from the same joint
- Caulk or the wrong sealant used in a wet area
For an older house near a landmark such as St Andrew's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

What else we do in Blackgang
How we quote for remedial sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
What you pay reflects the work, not guesswork. That is why we ask a few questions first.
What we need to know
When you call or email, these details help:
- The address or postcode of the job
- Access, such as stairs, a lift or height
- Whether it’s a home or a business
- The problem you’ve noticed
For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we’ll talk you through the work.
How the visit works
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours, depending on how many layers have to come out. Somewhere like Blackgang 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.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
Before we arrive
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on

Advice
Questions from Blackgang
Is Blackgang in your area for remedial sealant?
Yes. Our work covers London and the South East, and Blackgang is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Will you come out to Blackgang?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Someone sealed over the old bead. Can you fix it?
Yes. We remove every layer; new silicone does not bond to old silicone, which is why over-sealing fails.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Do you work for landlords and businesses?
Yes. As well as householders, we work for landlords, agents, businesses and hotels.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you when we finish.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Blackgang homes and their sealant
Blackgang is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Managing a site like Niton Primary School? Then 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.
Blackgang is about 6 miles south-west of Shanklin, in the Isle of Wight. From the centre of Blackgang to the outskirts, remedial sealant is available for homes and businesses alike. 125 places in the Isle of Wight are on our list, from the larger towns to small villages. We also work in Portsmouth, around 18 miles away.
Every address in PO38 is within our area for remedial sealant, from the main roads to the quietest streets. Neighbouring places we cover for remedial sealant include Chale (1 mile north-west), Niton (1 mile east), Puckaster (1 mile south-east), Pyle (1 mile north-west) and Bierley (1 mile north-east). We also work in nearby towns such as Newport (8 miles north), Ryde (11 miles north-east), Cowes (12 miles north), Sandown (8 miles north-east), Shanklin (6 miles north-east) and Ventnor (4 miles east). For island and remote addresses, a little more planning is needed.

What sealant work cannot fix
In fairness, some problems need a different trade:
- Sealant in an older building that needs testing for asbestos first
- A cracked shower tray or bath (that needs repair or replacing)
- A tray or worktop that needs refixing first
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before you book.
Joints and surfaces we work on
- Leaking tray & enclosure joints
- Failed movement joints
- Expansion joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Shrunken worktop sealant
Why act early in Blackgang
Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. Around Blackgang, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why Blackgang clients choose us
- Sealant colour chosen to suit
- Tidy, careful work
- Old sealant always removed completely
- We are fully insured
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Always have old sealant cut out, not covered
- Never fill a movement joint with mortar or grout
- Look for stains below bathrooms now and then
- Deal with small splits early
Where we have pointed out another fault, have it put right, because the new sealant cannot hold back a problem underneath.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
