About our remedial sealant in Bicknor
Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out. We work on leaking tray & enclosure joints, botched or over-sealed joints and expansion joints, and the jobs we see most are sealant applied over old sealant that has lifted and movement joints that have split or pulled away.
Somewhere as small as Bicknor, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
Whatever the size of the job, it’s backed by our 12-month guarantee in Bicknor and across Kent.

Your questions about remedial sealant in Bicknor
Will you come out to Bicknor?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Hollingbourne station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
What happens if the problem is the tray or the plumbing?
Then we explain what we have found. A plumber or fitter may be needed before any new sealant goes on.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Does someone need to be in?
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.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. First we check whether the leak is the sealant at all, then the joints are stripped and resealed.
Can you strip sealant from an acrylic tray safely?
Yes. We take our time over removal, especially on acrylic, enamel and uPVC.
Surface by surface
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant won’t fix it. We say so rather than reseal.
Windows & doors
Frames resealed over the top end up with hard, layered mastic. We remove it all and clean back to sound surfaces before backing and resealing.
Looking after it afterwards
So the new joints stay in good condition:
- Keep an eye on the ceiling below the bathroom
- Keep bleach and abrasives off the bead
- Never seal over old silicone
- Deal with small splits early
Don’t let anyone seal over it later. New silicone doesn’t bond to old.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
Bicknor homes and their sealant
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Letting a property close to Hollingbourne station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

Other services in Bicknor
When something else is needed
We will not take on work that will not last, so these are the limits:
- Cracks in the fitting rather than the joint
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Failed tanking or loose tiles behind the sealant
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before booking.
Joints and surfaces we work on
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Expansion joints
- Shrunken worktop sealant
- Failed movement joints
- Mouldy bath & shower sealant
Why deal with it now?
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. Around Bicknor, 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 usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

The process
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. It usually takes a few hours, depending on how many layers have to come out. Somewhere as small as Bicknor, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks
- Move anything stored near the joints
Ask for a quote

Related advice
What we’re called out for in Bicknor
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints split any bead that is too stiff or too thin.
Signs it’s time to call us include:
- Worktop sealant that has shrunk and split
- Over-sealed joints coming away
- Decorators’ caulk around a bath or shower
- Sealant that came away because the surface wasn’t prepared
Homes close to Church of St James include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Questions to ask before booking
- How long the guarantee is
- Who turns up on the day
- Whether they seal over old material or remove it
