What remedial sealant looks like in New Yatt
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For site and facilities teams at buildings such as North Leigh Church of England (Controlled) School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. For an older house near a landmark such as St Mary's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Remedial sealant in New Yatt
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, without scratching tiles, trays or frames. Only then can new sealant bond. We work on expansion joints, mouldy bath & shower sealant and shrunken worktop sealant, and common reasons people get in touch are mould trapped under a layer of silicone and smears and lumps from a botched reseal.
Being in a small place like New Yatt makes no difference to the job itself: it just means planning the journey and access beforehand. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

Common problems we fix in New Yatt
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
The problems people normally mention when they call are:
- Wide, uneven beads that look worse than the old ones
- Dark patches showing through the sealant
- Decorators’ caulk around a bath or shower
- Beads that never stuck properly
Rented homes near Finstock station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
What your quote should include
- What product goes in the joint
- How the surfaces are prepared before sealing
- Whether VAT is included
- What the cure time is
When something else is needed
A few problems are outside what sealant work can do:
- A cracked shower tray or bath (that needs repair or replacing)
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A bath, tray or worktop that moves until it’s properly fixed
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.

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. All told, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. In a small place like New Yatt, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- Finally we finish the joint and talk you through what we found.
Getting ready for the visit

Leave it or put it right?
A joint that has failed twice will fail again unless the cause is dealt with. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. In a small place like New Yatt, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Surface by surface
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, which we will point out.
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. All of it is cut out and the frame and wall cleaned.

Yes. There’s usually a reason: sealant over sealant, movement or another leak, and we deal with the cause first.

It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
