Remedial sealant in Petham
Water on the floor does not always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that’s what we find, we’ll tell you rather than reseal something that will not fix it. Typical jobs include worktop sealant that has shrunk and split and wide, uneven beads that look worse than the old ones, across mouldy bath & shower sealant, botched or over-sealed joints and leaking tray & enclosure joints.
For a small place like Petham, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. In the bathroom or kitchen, the work is the same as in any town.
Big or small, it’s backed by our 12-month guarantee in Petham and across Kent.

Bathrooms and kitchens in Petham
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a building such as Petham Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. Rented homes near Chartham station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Do you need remedial sealant in Petham?
Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes split any bead that is too stiff or too thin.
The most common problems we see are:
- Mould trapped under a layer of silicone
- Products that weren’t meant for the joint
- Smears and lumps from a botched reseal
- Sealant peeling off a dusty or damp surface
For an older house near a landmark such as Church of All Saints, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Petham: your questions answered
Is Petham within the area you cover?
Yes. Petham is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Petham in your area for remedial sealant?
Yes, Petham is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Are you fully insured?
Yes. Full insurance covers our work.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected.
Can old silicone be taken off without scratching the tiles?
Yes. We take our time over removal, especially on acrylic, enamel and uPVC.
Quotes for remedial sealant in Petham
Jobs vary more than people expect. The main factors:
- Any working-time requirements on site

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Use a soft cloth, not a scourer, on silicone
- Do not add new sealant on top of old
- Report a tray that rocks or a worktop that lifts
- Air the bathroom so the sealant can dry
Where we’ve pointed out another fault, have it put right, or the new joint may fail again.
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. Any of them means it’s time for remedial work.
Why act early in Petham
Adding more sealant is the usual quick fix, and it rarely works. It does not grip the old layer, so the leak carries on and there’s now more to remove. In a small place like Petham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

What the job involves on each surface
Movement & expansion joints
Joints filled with mortar, grout or rigid filler can’t move. We rake that out where it can be removed and seal with a flexible product.
Mouldy bath & shower sealant
Repeat mould generally points to a damp, poorly aired room. Along with resealing, we will mention if the room needs better ventilation.
What happens on the day
The work is kept neat and contained to the area we are working on. Expect the work to take a few hours for a typical bath or shower, longer where several layers have been applied, and we tell you how long to leave it before we go. Somewhere as small as Petham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
How to prepare
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in

Related advice
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
