Northiam Remedial Sealant
Removing failed, mouldy or leaking sealant and putting it right in Northiam, with a 12-month guarantee on every job. Call for a quick quote.
- Worktop sealant that has shrunk and split
- A shower that leaks however often it’s resealed
- Decorators’ caulk around a bath or shower
Why deal with it now?
Adding more sealant is the usual quick fix, and it rarely works. It does not grip the old layer, so the leak carries on and there’s now more to remove. Older cottages and farmhouses around Northiam can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why us?
- Neat joints and a tidy finish
- 12-month guarantee on every job
- Sealant colour chosen to suit
- Any old sealant cut out fully, not covered over
How we handle remedial sealant in Northiam
A joint that keeps failing generally has a reason. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. Finding that cause comes before any new sealant. If you have black mould underneath the bead and floor or wall movement joints that have failed, we can put it right, whatever the surface.
Being in a small place like Northiam makes no difference to the job itself: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.
Our work is backed for twelve months.

Common questions in Northiam
Is there a guarantee on remedial sealant in Northiam?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can you do remedial sealant in Northiam?
Yes, Northiam is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
What if the leak is not the sealant?
You will hear it from us. A cracked tray, faulty valve or leaking waste needs a different trade, and we will not reseal for the sake of it.
Someone sealed over the old bead. Can you fix it?
Yes. Both layers come out; new silicone does not bond to old silicone, which is why over-sealing fails.
Can you fix a reseal that hasn’t worked?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.

Common problems we fix in Northiam
Using the wrong product is a common cause: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. None of them last.
The most common problems we see are:
- Leaks that keep coming back after resealing
- Floor or wall movement joints that have failed
- Beads that never stuck properly
- Caulk or the wrong sealant used in a wet area
For site and facilities teams at buildings such as Northiam Church of England Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Questions to ask before booking
- Whether the sealant suits the joint
- Which colour the sealant will be
- Whether VAT is included
- How the surfaces are prepared before sealing
Honest limits
We won’t take on work that won’t last, so here’s what sealant can’t put right:
- Movement from fittings that aren’t supported
- Water damage behind tiles that needs a tiler
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.

Remedial sealant in Northiam: local notes
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Act on a lifting corner right away
- Look for stains below bathrooms now and then
- Keep movement joints clear of mortar and paint
- Keep bleach and abrasives off the bead
Watch the joint over the first few weeks, especially if movement was the problem. Should anything change, phone 0345 464 0079 or drop us an email.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
How it works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere like Northiam 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.
- We start by checking the joint for movement, leaks and the reason it failed.
- All the old sealant comes out, including any layers underneath.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
How to prepare
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
