Kemsing Remedial Sealant
We cover Kemsing for removing failed, mouldy or leaking sealant and putting it right. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Movement joints that have split or pulled away
- Products that weren’t meant for the joint
- Wide, uneven beads that look worse than the old ones
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
How we handle remedial sealant in Kemsing
Some sealant jobs aren’t a simple reseal, because someone has already had a go. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all have to come out. We work on botched or over-sealed joints, mouldy bath & shower sealant and expansion joints, and people most often call us about sealant applied over old sealant that has lifted and gaps opening along the back of the worktop.
Homes around Kemsing range from older cottages to more recent houses. Older homes can move a little with the seasons, which is hard on tired sealant and rigid grout.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Questions from Kemsing
I let a flat near Otford station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Do you cover smaller places like Kemsing?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
How much does remedial sealant cost in Kemsing?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Can failed expansion joints be resealed?
Yes. The depth is set with backing so the sealant only bonds to the two sides.
Can old silicone be taken off without scratching the tiles?
Yes. We take our time over removal, particularly on softer surfaces like acrylic.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or send us an email.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.

- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- When we can work, for business premises
- Mould in or behind the old joints
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Bathrooms and kitchens in Kemsing
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around Church of St Mary, walls and floors in older homes can move, and sealant and grout show it first. If you let a flat or house near Otford station, a joint that keeps failing is best fixed properly while the property is empty.

What happens on the day
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for a typical bath or shower, longer where several layers have been applied in most cases. For a job in Kemsing, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks

Advice
What we are called out for in Kemsing
A lot of failed joints have been sealed over rather than replaced. New silicone can’t stick to the old bead, so the top layer lifts and water and mould collect between the two.
Signs it’s time to call us include:
- Movement joints that have split or pulled away
- Repeat leaks from the same joint
- Products that weren’t meant for the joint
- Sealant applied over old sealant that has lifted
Schools such as Kemsing Primary 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.

Surface by surface
Windows & doors
Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant will not fix it. We say so rather than reseal.
Landlord and commercial work in Kemsing
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Never fill a movement joint with mortar or grout
- Don’t add new sealant on top of old
- Find out why the sealant failed first
- Have loose fittings fixed before resealing
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant can’t hold back a problem underneath.
Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.
