Common problems we fix in Codicote Bottom
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 most common problems we see are:
- Caulk or the wrong sealant used in a wet area
- Sealant applied over old sealant that has lifted
- Torn expansion joints
- Gaps opening along the back of the worktop
For landlords with property near Welwyn North station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Remedial sealant for homes and businesses in Codicote Bottom
Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. When the fault is elsewhere, we say so instead of resealing for the sake of it. We work on shrunken worktop sealant, leaking tray & enclosure joints and botched or over-sealed joints, and the jobs we see most are thick, messy sealant smeared over tiles and movement joints that have split or pulled away.
For a small place like Codicote Bottom, 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.
Our work is backed for twelve months, in Codicote Bottom and everywhere else we cover.

The process
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours, depending on how many layers have to come out for a typical job. Somewhere as small as Codicote Bottom, access is often the only tricky part. 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.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property

Keeping the joints in good condition
So the new joints stay in good condition:
- Find out why the sealant failed first
- Use a soft cloth, not a scourer, on silicone
- Have loose fittings fixed before resealing
- Don’t add new sealant on top of old
If the joint ever needs renewing, have it cut out, not sealed over. New silicone does not bond to old, so the old bead should always come out first.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Early action keeps it to a sealant job.
Codicote Bottom homes and their sealant
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.
For an older house near a landmark such as Parish Church of St Giles, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. If you look after a building such as Codicote Church of England Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

Honest limits
Sealant is not the answer to every problem, and we’ll tell you before we start. Sealant won’t put right:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Sealant in an older building that needs testing for asbestos first
- Movement from fittings that aren’t supported

Places near Codicote Bottom
What else we do in Codicote Bottom
Different surfaces, different methods
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so we spend extra time cleaning before resealing.
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated so the new sealant starts clean.
Leave it or put it right?
Adding more sealant is the usual quick fix, and it rarely works. It doesn’t grip the old layer, leaving the leak in place and one more layer to cut out later. Older cottages and farmhouses around Codicote Bottom can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Do you cover smaller places like Codicote Bottom?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
How long should I leave it?

Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
