Colthrop Remedial Sealant
Our applicators work in Colthrop on removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly.
- Movement joints that have split or pulled away
- Kitchen joints letting water behind the worktop
- Mould trapped under a layer of silicone
Honest limits
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- A tray or worktop that needs refixing first
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- A tray or bath that is cracked
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.
Where we work in Colthrop
- Expansion joints
- Failed movement joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Shrunken worktop sealant
- Leaking tray & enclosure joints
Remedial sealant in Colthrop, done properly
Not every leak is a sealant leak. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that is what we find, we will tell you rather than reseal something that won’t fix it. We’re often asked to deal with a shower that leaks however often it’s resealed and thick, messy sealant smeared over tiles, on shrunken worktop sealant, botched or over-sealed joints and mouldy bath & shower sealant.
For a small place like Colthrop, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

What else we do in Colthrop
Colthrop: your questions answered
I let a flat near Thatcham station. Can you help?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Colthrop?
Yes, Colthrop is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Does remedial work come with a guarantee?
Yes, with our 12-month guarantee. Where we’ve flagged another fault, it needs fixing for the joint to last.
How long will it take to strip and reseal the joint?
A little longer than a standard reseal. Most jobs take a few hours.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
Can I choose the sealant colour?
In most cases you can choose. We’ll explain which colours are available and agree one before we start.
Someone sealed over the old bead. Can you fix it?
Yes. Both layers come out; new silicone does not bond to old silicone, which is why over-sealing fails.
My shower still leaks after a reseal. Can you sort it?
Yes. We’ll take all the sealant out, look for why it failed and reseal it properly.
Remedial sealant around Colthrop
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Rented homes near Thatcham station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants. In the older streets around St Mary's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Don’t point over movement joints
- Deal with small splits early
- Check ceilings under showers for marks
- Get the cause of a repeat leak found before resealing
Give the new sealant its full cure time: follow the cure time we give you.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Sorting it early limits the damage.
Signs you need remedial sealant in Colthrop
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints split any bead that is too stiff or too thin.
Signs it’s time to call us include:
- Repeat leaks from the same joint
- A second bead peeling off the first
- Beads that never stuck properly
- Thick, messy sealant smeared over tiles
If you look after a building such as Francis Baily Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

How the visit works
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on how many layers have to come out. For a village or hamlet like Colthrop, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- 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.
Before we arrive
- Mention any tricky access
- Clear items away from the joints we’re working on
- For indoor joints, keep the area dry beforehand if you can

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
