What remedial sealant looks like in Blackwater
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
Homes close to St Barnabas Church include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. Schools such as Frogmore Infant School are buildings too, and 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.

Your questions about remedial sealant in Blackwater
Can you do remedial sealant in Blackwater?
Yes. Our work covers London and the South East, and Blackwater is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.
Do you cover smaller places like Blackwater?
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.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
Can you match the sealant colour?
Generally, yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
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, and the residue is cleaned away. Any existing damage is pointed out before we start.
What if resealing will not fix my leak?
We check for that before we reseal. If the fault is elsewhere, you will know before any work is done.
What happens on the day
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. For a job in Blackwater, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Preparing for the visit
- On commercial sites, let us know about site rules
- Clear the area around the work
- Keep pets and children clear of the area while we work

Advice
What else we do in Blackwater
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Do not point over movement joints
- Use a soft cloth, not a scourer, on silicone
- Do not add new sealant on top of old
- Find out why the sealant failed first
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
What affects the cost of remedial sealant
Jobs vary more than people expect. What affects the quote:
- Whether old sealant or filler has to be cut out
- Whether the work is at height
- How much there is to do
- Any mould that needs treating
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- The problem you’ve noticed
- The address or postcode of the job
- Photos by email, if that is easy
- Any access issues, like height or stairs
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or send us an email.
What we cannot put right
It helps to know what we cannot do too:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A leaking trap, valve or supply pipe
- A tray or bath that is cracked
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.
What we seal
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Expansion joints
- Failed movement joints
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Why act early in Blackwater
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. Removal is the only way to get at it, so the joint can be treated and resealed. In an older home around Blackwater, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or email us and we’ll talk you through it.

What we’re called out for in Blackwater
Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.
Common reasons people contact us are:
- Over-sealed joints coming away
- Leaks that keep coming back after resealing
- Floor or wall movement joints that have failed
- Sealant that came away because the surface wasn’t prepared
For landlords with property near Blackwater station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

- How the joint is cleaned and prepared
- What happens if the job turns out different
- Whether all the old sealant comes out first
- What product goes in the joint
