How we handle remedial sealant in Blackwater
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 beat any new bead. We look for the cause before we reseal. We’re often asked to deal with products that weren’t meant for the joint and wide, uneven beads that look worse than the old ones, across leaking tray & enclosure joints, botched or over-sealed joints and shrunken worktop sealant.
For a small place like Blackwater, 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.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Landlord and commercial work in Blackwater
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.

Yes, Blackwater is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.
Will you come out to Blackwater?

Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or email us.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Do you have insurance?
Yes. We are fully insured.
When it isn’t the sealant
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- A bath, tray or worktop that moves until it’s properly fixed
- Sealant in an older building that needs testing for asbestos first
- Tiles that have come away from the wall
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before booking.
Surfaces we seal
- Failed movement joints
- Expansion joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Shrunken worktop sealant
Why deal with it now?
Spraying mould remover on a sealed-over joint does not reach what’s underneath. The layers have to come out. Around Blackwater, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
Why us?
- Tidy, careful work
- Arbo and Everbuild products

How it works
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. Somewhere like Blackwater needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Surrounding tiles, trays and frames are protected first.
- 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.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property
- Clear items away from the joints we are working on
How to get a quote

Advice
Blackwater homes and their sealant
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
If you look after a building such as Christ The King College, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. In the older streets around St. Olave's Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

How the job changes by surface
Mouldy bath & shower sealant
Black mould inside the bead won’t scrub out. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.
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.
