Remedial sealant for homes and businesses in Cobham
Some sealant jobs are not 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 need stripping out. If you are dealing with thick, messy sealant smeared over tiles and kitchen joints letting water behind the worktop, we can help, on mouldy bath & shower sealant, shrunken worktop sealant and leaking tray & enclosure joints alike.
For a small place like Cobham, 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.
Whatever the size of the job, you get the same one-year guarantee.

Common problems we fix in Cobham
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
These are the problems we’re asked about most:
- Kitchen joints letting water behind the worktop
- Black mould underneath the bead
- A second bead peeling off the first
- Floor or wall movement joints that have failed
If you live in an older home near Parish Church of St Mary Magdalene, walls and floors in older homes can move, and sealant and grout show it first.
Questions to ask before you book
- What the cure time is
- Who does the work, and how experienced they are
- What guarantee comes with the work
- What happens if they find a problem under the old sealant
What remedial sealant looks like in Cobham
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 site and facilities teams at buildings such as Cobham 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. For landlords with property near Sole Street station, a joint that keeps failing is best fixed properly while the property is empty.

Your questions about remedial sealant in Cobham
Is Cobham in your area for remedial sealant?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Are you insured?
Yes. We’re fully insured.
How long will it take to strip and reseal the joint?
Longer than a simple reseal, because every layer has to come out. For most joints, it’s a few hours.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few photos.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us.
The process
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours, depending on how many layers have to come out, depending on the size of the job. In a small place like Cobham, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- Finally we finish the joint and talk you through what we found.
Preparing for the visit
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Do not add new sealant on top of old
- Check trays and worktops do not move
- Get the cause of a repeat leak found before resealing
- Check ceilings under showers for marks
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- A leaking trap, valve or supply pipe
- Movement from fittings that are not supported
- A cracked shower tray or bath (that needs repair or replacing)
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.
