When it is not the sealant
It helps to know what we can’t do too:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A cracked shower tray or bath (that needs repair or replacing)
- Failed tanking or loose tiles behind the sealant
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.
What we seal
- Leaking tray & enclosure joints
- Expansion joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Shrunken worktop sealant
- Failed movement joints
How the job changes by surface
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, including the smears and film on surrounding tiles. New sealant needs a fully clean surface.
Mouldy bath & shower sealant
Black mould inside the bead will not scrub out. The sealant is cut out completely, the joint treated with a mould remover and dried before anti-fungal sanitary silicone goes in.
Quotes for remedial sealant in Great Coxwell
The quote reflects the job in front of us. We take into account:
- When we can work, for business premises
- How easy the joints are to reach

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

- Whether it’s a home or a business

The process
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on how many layers have to come out. Somewhere like Great Coxwell needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in

Bathrooms and kitchens in Great Coxwell
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 Faringdon Community College, we reseal washrooms and kitchens in schools and businesses as well as homes. Homes close to Church of St Giles include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

Your questions about remedial sealant in Great Coxwell
Will you come out to Great Coxwell?

What guarantee comes with remedial sealant in Great Coxwell?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
How long does the work take?
That depends on how many layers there are and how many joints. We’ll tell you before we start.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
Do you work for landlords and businesses?
Yes. As well as householders, we work for landlords, agents, businesses and hotels in Great Coxwell.
How much does remedial sealant cost in Great Coxwell?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or email us and let us know what needs doing and where.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Where do you work from?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Keeping the joints in good condition
So the new joints stay in good condition:
- Run the fan after every shower
- Do not point over movement joints
- Keep an eye on the ceiling below the bathroom
- Check trays and worktops do not move
Where we’ve pointed out another fault, have it put right, because the new sealant cannot hold back a problem underneath.
Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Each one is worth getting looked at.
Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
