Remedial sealant for homes and businesses in Densole
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. If you are dealing with gaps opening along the back of the worktop and thick, messy sealant smeared over tiles, we can put it right.
For a small place like Densole, 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.
All our work is covered by a 12-month guarantee, wherever you are in Kent.

When to call us in Densole
One of the commonest remedial jobs is sealant on top of sealant. New silicone can’t stick to the old bead, so the new layer peels, and damp and mould settle between them.
People generally contact us when they notice one of these:
- Floor or wall movement joints that have failed
- Thick, messy sealant smeared over tiles
- Kitchen joints letting water behind the worktop
- Mould trapped under a layer of silicone
Schools such as Hawkinge Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

How the job changes by surface
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We work carefully to avoid adding to it, and point out any existing damage.
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, in a colour that suits the frame.
Densole homes and their sealant
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For an older house near a landmark such as St Luke's, timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you let a flat or house near Folkestone West station, botched sealant from a previous quick fix is easier to strip out between tenants.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Landlords, agents and businesses in Densole
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.
Common questions in Densole
Is Densole within the area you cover?
Yes. Densole 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 Densole in your area for remedial sealant?
Yes. We work across London and the South East, and Densole is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
My shower still leaks after a reseal. Can you sort it?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
Can you reseal a split movement joint?
Yes. Where mortar or filler has been used instead of sealant, it’s removed where it can be, then the joint is sealed properly.
Are you fully insured?
Yes. Full insurance covers our work.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Why act early in Densole
DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. Around Densole, 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 reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

What we do, step by step
There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours, depending on how many layers have to come out, including the tidy-up. In a small place like Densole, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
How to prepare
- Mention any tricky access
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive
