Remedial sealant in Neatham
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We are fully insured ARBOMaster approved applicators, and every remedial job comes with a 12-month guarantee. We work on mouldy bath & shower sealant, leaking tray & enclosure joints and failed movement joints, and the jobs we see most are smears and lumps from a botched reseal and over-sealed joints coming away.
In a village or hamlet like Neatham, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Work for landlords, hotels and businesses
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
For anyone letting property in or around Neatham, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- A leaking trap, valve or supply pipe
- Movement from fittings that are not supported
- Failed tanking or loose tiles behind the sealant
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
What we seal
- Failed movement joints
- Expansion joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Botched or over-sealed joints
- Leaking tray & enclosure joints
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Signs you need remedial sealant in Neatham
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks. At that point it has to come out.
These are the problems we are asked about most:
- Thick, messy sealant smeared over tiles
- Leaks that keep coming back after resealing
- Torn expansion joints
- Sealant peeling off a dusty or damp surface
In the older streets around Holy Rood Church, older homes can move a little, which is hard on rigid grout and tired sealant.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Find out why the sealant failed first
- Act on a lifting corner straight away
- Always have old sealant cut out, not covered
- Keep movement joints clear of mortar and paint
Don’t let anyone seal over it later. Over-sealing is how many remedial jobs start.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
How it works
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work starts. The work normally takes a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere as small as Neatham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
How to prepare
- Let us know about parking restrictions
- Clear the area around the work
- Try not to wet indoor joints just before the visit

Why act early in Neatham
DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. In a small place like Neatham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
