How we handle remedial sealant in Avon Castle
Water on the floor does not always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. When the fault is elsewhere, we say so instead of resealing for the sake of it. If you’re dealing with leaks that keep coming back after resealing and decorators’ caulk around a bath or shower, we can put it right, whatever the surface.
In a village or hamlet like Avon Castle, 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.
Each job carries a 12-month guarantee.

Common questions in Avon Castle
Will you come out to Avon Castle?
Yes. Avon Castle is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Avon Castle in your area for remedial sealant?
Yes, Avon Castle is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Is remedial work guaranteed?
Yes, for 12 months. If we’ve pointed out another problem, getting it fixed helps the new joint last.
How long does the work take?
Longer than a simple reseal, because every layer has to come out. For most joints, it’s a few hours.
Can old silicone be taken off without scratching the tiles?
Yes, with care. We cut and lift the old sealant with tools suited to the surface, then clean off the residue. Any existing damage is pointed out before work begins.
Can you reseal a split movement joint?
Yes. Backing sets the depth and stops the sealant sticking to the back.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Signs you need remedial sealant in Avon Castle
Water from somewhere else can ruin a good seal. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.
Any of these means the joints need attention:
- Black mould underneath the bead
- Torn expansion joints
- Sealant applied over old sealant that has lifted
- Caulk or the wrong sealant used in a wet area
Schools such as St Ives Primary & Nursery School are buildings too, and 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.

What we do, step by step
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work starts. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. Somewhere as small as Avon Castle, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking the joint for movement, leaks and the reason it failed.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
How to prepare
- Move anything stored near the joints
- Mention any parking rules near the property
- Keep children and pets away from the work area

If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.
What we seal
- Expansion joints
- Failed movement joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Botched or over-sealed joints
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What happens if it’s left?
Ripping out a bathroom isn’t generally needed. If the bath, tray and tiles are sound, remedial resealing normally puts it right. If they’re not, we’ll tell you. In a small place like Avon Castle, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why book with us
- A sealant colour to suit the surroundings
- Experience in homes, commercial sites and hotels
- Old sealant always removed completely
- 20+ years of sealant experience

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Air the bathroom so the sealant can dry
- Clean sealant with mild products only
- Never fill a movement joint with mortar or grout
- Act on a lifting corner straight away
Do not let anyone seal over it later. New silicone does not bond to old.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
Landlords, agents and businesses in Avon Castle
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
