How the job changes by surface
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We take care not to make it worse, and tell you about any damage we find.
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. We strip it, degrease the joint and reseal colour-matched to the worktop.
How we handle remedial sealant in Sibertswold
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We’re ARBOMaster approved and fully insured, and remedial work carries our 12-month guarantee. If you have black mould underneath the bead and a shower that leaks however often it’s resealed, we can put it right.
Being in a small place like Sibertswold makes no difference to the job itself: it just means planning the journey and access beforehand. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
Whatever the size of the job, you get the same one-year guarantee in Sibertswold and across Kent.

What affects the quote in Sibertswold
We quote each job individually. This is what makes a difference:
- The product the joint needs
- When we can work, for business premises
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
What we need to know
Photos help, but a description is a good start. Please mention:
- A few photos by email, if you can
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
- Whether it’s a home or a business
Getting a quote is simple: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we will come back to you with a quote.
When to call us in Sibertswold
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints split any bead that’s too stiff or too thin.
These are the problems we’re asked about most:
- A second bead peeling off the first
- Wide, uneven beads that look worse than the old ones
- Decorators’ caulk around a bath or shower
- Worktop sealant that has shrunk and split
Rented homes near Shepherds Well station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.
What to look for in a quote
- Whether you can choose the colour
- Is the old sealant removed completely?
- Who does the work, and how experienced they are
- What happens if the job turns out different
What remedial sealant looks like in Sibertswold
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you live in an older home near Church of St Andrew, older homes can move a little, which is hard on rigid grout and tired sealant.

Common questions in Sibertswold
Will you come out to Sibertswold?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Shepherds Well station?
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’ll give you a fixed price before we start.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator.
How much does remedial sealant cost in Sibertswold?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before any work starts.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
What sealant work can’t fix
We will not take on work that will not last, so these are the limits:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A tray or bath that’s cracked
- Movement from fittings that aren’t supported
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly before you book.
Joints and surfaces we work on
- Shrunken worktop sealant
- Failed movement joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Expansion joints
What happens if it’s left?
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. In a small place like Sibertswold, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.
