Professional remedial sealant in and around Newchurch, with every bit of old sealant taken out first.

- Caulk or the wrong sealant used in a wet area
- Over-sealed joints coming away
Different surfaces, different methods
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant will not fix it. We’ll tell you what we find.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We work carefully to avoid adding to it, and tell you about any damage we find.
Remedial sealant in Newchurch, done properly
Two decades of sealant work means we recognise most failures quickly. We’re fully insured ARBOMaster approved applicators, and every remedial job comes with a 12-month guarantee. We work on leaking tray & enclosure joints, mouldy bath & shower sealant and shrunken worktop sealant, and the jobs we see most are wide, uneven beads that look worse than the old ones and caulk or the wrong sealant used in a wet area.
Somewhere as small as Newchurch, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
Every job comes with our 12-month guarantee, wherever you are in Kent.

Questions from Newchurch
Can you do remedial sealant in Newchurch?
Yes, Newchurch is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
I let a flat near Ham Street station. Can you help?
Yes, we work for letting agents and landlords. You can phone 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 if resealing will not fix my leak?
You will hear it from us. A cracked tray, faulty valve or leaking waste needs a different trade, so we will not pretend it will.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Can you strip sealant from an acrylic tray safely?
Yes. Residue is removed with a product suited to the surface rather than scraped hard.
Can I add another job to the visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Is remedial work guaranteed?
Yes, for 12 months. If we’ve pointed out another problem, getting it fixed helps the new joint last.
Can I choose the sealant colour?
Most of the time, yes. We will explain which colours are available.
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
How it works
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on the amount of work. For a village or hamlet like Newchurch, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before
Getting a quote
Getting a quote is simple: let us know what needs doing and where. A few photos by email make the job easier to understand.
Advice
Leave it or put it right?
Adding more sealant is the usual quick fix, and it rarely works. It cannot bond to what’s underneath, so the leak carries on and there’s now more to remove. Where a wall is exposed, as many are in small places like Newchurch, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

Looking after it afterwards
So the new joints stay in good condition:
- Act on a lifting corner straight away
- Find out why the sealant failed first
- Don’t point over movement joints
- Run the fan after every shower
Keep an eye on the joint at first, especially if movement was the problem. Should anything change, ring 0345 464 0079 or email us.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
When to call us in Newchurch
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould, faster where ventilation is poor. Then the only fix is removal and a new bead.
People generally contact us after spotting one of these:
- Kitchen joints letting water behind the worktop
- Smears and lumps from a botched reseal
- Floor or wall movement joints that have failed
- Dark patches showing through the sealant
In the older streets around Church of St Peter and St Paul, older homes can move a little, which is hard on rigid grout and tired sealant.
Questions to ask before you book
- Whether they’re fully insured
- What happens if they find a problem under the old sealant
- What product goes in the joint
- Which colour the sealant will be

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- A leaking trap, valve or supply pipe
- Movement from fittings that are not supported
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before you book.
