About our remedial sealant in Newtown
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. Typical jobs include floor or wall movement joints that have failed and wide, uneven beads that look worse than the old ones, across mouldy bath & shower sealant, failed movement joints and botched or over-sealed joints.
In a village or hamlet like Newtown, 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.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
FAQs for Newtown
Do you work for landlords with property near Portchester station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Is Newtown in your area for remedial sealant?
Yes. We work across London and the South East, and Newtown is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
What if the leak isn’t the sealant?
That’s why we look for the cause first. If the fault is elsewhere, you’ll know before any work is done.
How long does the work take?
That depends on how many layers there are and how many joints. We’ll tell you before any work starts.
Is it messy?
We keep the work tidy. We protect what’s around the joints.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Signs you need remedial sealant in Newtown
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, so it starts lifting sooner than it should.
Look out for these signs:
- Gaps opening along the back of the worktop
- Leaks that keep coming back after resealing
- Smears and lumps from a botched reseal
- Black mould underneath the bead
For landlords with property near Portchester station, a joint that keeps failing is best fixed properly while the property is empty.

If the job is outside, mention outbuildings, exposed walls and how to reach them.

Advice
What remedial sealant looks like in Newtown
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
If you live in an older home near Church of the Holy Trinity, walls and floors in older homes can move, and sealant and grout show it first. Schools such as Newtown Soberton Infant School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

Why act early in Newtown
A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing generally puts it right. If they’re not, we’ll tell you. In a small place like Newtown, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Surface by surface
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
Mouldy bath & shower sealant
Repeat mould generally points to a damp, poorly aired room. We’ll reseal and tell you if extraction looks to be the issue.
Looking after it afterwards
So the new joints stay in good condition:
- Report a tray that rocks or a worktop that lifts
- Run the fan after every shower
- Keep movement joints clear of mortar and paint
- Always have old sealant cut out, not covered
If the joint ever needs renewing, have it cut out, not sealed over. New silicone doesn’t bond to old.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
