Longcot Remedial Sealant
We cover Longcot for removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Caulk or the wrong sealant used in a wet area
- Leaks that keep coming back after resealing
- Movement joints that have split or pulled away
How we handle remedial sealant in Longcot
A joint that keeps letting you down needs more than another bead. Send photos when you ring 0345 464 0079 or email us, and say how long ago it was last done. We work on botched or over-sealed joints, leaking tray & enclosure joints and mouldy bath & shower sealant, and the jobs we see most are kitchen joints letting water behind the worktop and floor or wall movement joints that have failed.
Being in a small place like Longcot makes no difference to the job itself: it just means planning the journey and access beforehand. In the bathroom or kitchen, the work is the same as in any town.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

DIY sealant or a professional job?
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 doesn’t work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Why it’s worth doing now in Longcot
A failed seal rarely means a new bathroom. When the fittings are sound, stripping and resealing the joints is often enough. Where something else has failed, you’ll hear it from us. Around Longcot, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.

What happens on the day
At the end, we look at the finished work together. The visit itself normally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on the size of the job. Somewhere like Longcot needs a little journey planning: 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.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
- For business premises, tell us about site rules or sign-in

Bathrooms and kitchens in Longcot
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.
Managing a site like Longcot and Fernham Church of England Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Do you need remedial sealant in Longcot?
Water from somewhere else can ruin a good seal. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
Keep an eye out for any of the following:
- Sealant applied over old sealant that has lifted
- Black mould underneath the bead
- Smears and lumps from a botched reseal
- Leaks that keep coming back after resealing
Homes close to Church of St Mary include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

What the job involves on each surface
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, matched to the frame colour.
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, which we will point out.

Yes, Longcot is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear price.
Do you cover smaller places like Longcot?

Can landlords and businesses book you?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
How much does remedial sealant cost in Longcot?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can failed expansion joints be resealed?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, and reseal with a flexible product.
What we can’t put right
New sealant can’t fix everything, and we will tell you before any work starts. Sealant will not put right:
- A leaking trap, valve or supply pipe
- Movement from fittings that aren’t supported
- A cracked shower tray or bath (that needs repair or replacing)
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before booking.
