What remedial sealant looks like in Rock
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
If you look after a building such as St Mary's CofE Primary School, 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.

How we handle remedial sealant in Rock
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. If you have thick, messy sealant smeared over tiles and kitchen joints letting water behind the worktop, we can put it right.
For a small place like Rock, remedial sealant is planned like any other job: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.
A one-year guarantee comes as standard, so you are covered after we have gone.

Rock questions
Do you cover Rock for remedial sealant?
Yes, Rock is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Will you come out to Rock?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
What does remedial sealant cost?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Different surfaces, different methods
Worktops & kitchens
A loose worktop splits its sealant. It needs fixing down first, and we will tell you if we find it.
Movement & expansion joints
A sealant stuck to the back of the joint can’t stretch. Backing stops that, letting the sealant flex between the two faces.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Act on a lifting corner right away
- Check trays and worktops don’t move
- Get the cause of a repeat leak found before resealing
- Keep bleach and abrasives off the bead
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. Should anything change, phone 0345 464 0079 or drop us an email.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Sorting it early limits the damage.
What happens on the day
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere as small as Rock, 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.
- 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.
How to prepare
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed

Landlord and commercial work in Rock
If you manage several properties in or around Rock, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
What happens if it’s left?
Mould under a bead can’t be reached by cleaning. Removal is the only way to get at it, so the joint can be treated and resealed. Around Rock, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

Signs you need remedial sealant in Rock
One of the commonest remedial jobs is sealant on top of sealant. Silicone doesn’t bond to silicone, so the new layer peels, and damp and mould settle between them.
The problems people usually mention when they call are:
- Kitchen joints letting water behind the worktop
- Leaks that keep coming back after resealing
- Sealant peeling off a dusty or damp surface
- Floor or wall movement joints that have failed
For an older house near a landmark such as The Parish Church of St Mary, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
