Remedial sealant in Newport, done properly
Getting old sealant out properly is slow, careful work. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. Only then can new sealant bond. We work on botched or over-sealed joints, mouldy bath & shower sealant and failed movement joints, and common reasons people get in touch are leaks that keep coming back after resealing and smears and lumps from a botched reseal.
Homes around Newport have been extended and refitted over the decades. A common problem is new sealant laid over old, which never bonds properly, so we take every joint back to clean before anything new goes in.
Big or small, it’s backed by our one-year guarantee in Newport and across the Isle of Wight.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Look for stains below bathrooms now and then
- Check trays and worktops don’t move
- Use a soft cloth, not a scourer, on silicone
- Never seal over old silicone
Go easy on the new sealant: a mild cleaner and a soft cloth, with no blades or scourers.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
For landlords and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
When to call us in Newport
Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
Signs it’s time to call us include:
- Kitchen joints letting water behind the worktop
- Mould trapped under a layer of silicone
- Decorators’ caulk around a bath or shower
- Beads that never stuck properly
Managing a site like Nine Acres Primary School? Then washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

Honest limits
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- A tray or worktop that needs refixing first
- Plumbing leaks behind walls or under trays
- Sealant in an older building that needs testing for asbestos first
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

Why act early in Newport
Adding more sealant is the usual quick fix, and it rarely works. It doesn’t grip the old layer, leaving the leak in place and one more layer to cut out later. In a family home in Newport, a failed seal around a bath or a frame lets water into places you cannot see, such as under the floor, behind a panel or into a wall. Left alone, that means rot, damp and a bigger repair.
The cost depends on the amount of work, 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.
