Remedial sealant & repairs in Sunninghill, Windsor and Maidenhead
Problem with your failed sealant joints in Sunninghill? We remove the old material, prepare the joints and seal them properly.
- Black mould underneath the bead
- Gaps opening along the back of the worktop
- Leaks that keep coming back after resealing
Aftercare tips
After the cure time, these simple habits help:
- Get the cause of a repeat leak found before resealing
- Don’t point over movement joints
- Air the bathroom so the sealant can dry
- Act on a lifting corner straight away
Keep an eye on the joint at first, particularly where the original failure was caused by movement. If anything changes, just call 0345 464 0079 or drop us an email.
Signs to act on: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Any of them means it’s time for remedial work.
Remedial sealant for homes and businesses in Sunninghill
Remedial jobs in Sunninghill usually fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. Each is stripped back and done again properly. We work on failed movement joints, mouldy bath & shower sealant and botched or over-sealed joints, and common reasons people get in touch are gaps opening along the back of the worktop and caulk or the wrong sealant used in a wet area.
Around Sunninghill, you will mostly find houses and bungalows, some older and some much newer. Sealant and grout wear out here just as they do in a big town.

Common questions in Sunninghill
Can you help a landlord with a rental near Ascot station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Is Sunninghill within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you remove sealant that is been put over old sealant?
Yes. Each layer is cut out and the residue cleaned off, then the joint is resealed once.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Do you offer different sealant colours?
Most of the time, yes. We will tell you which colours the right product comes in and agree one before any work starts.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Different surfaces, different methods
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, including the smears and film on surrounding tiles. New sealant needs a fully clean surface.
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. We strip it, degrease the joint and reseal.
When it isn’t the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Older mastics that may need an asbestos check before removal
- A cracked shower tray or bath (that needs repair or replacing)
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

What remedial sealant looks like in Sunninghill
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
If you look after a building such as St Michael's CofE Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. Rented homes near Ascot station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.

How we quote for remedial sealant
Every job gets its own quote. This is what makes a difference:
- The number of rooms or windows
- Whether the work is at height
- Whether there’s mould to deal with
- The number and length of the joints
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
What we need to know
When you contact us, it’s useful to know:
- Photos by email, if that is easy
- If it’s domestic, commercial or a hotel
- Where the property is
- The problem you’ve noticed
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work and give you a clear quote.
What we do, step by step
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours, depending on how many layers have to come out, depending on the size of the job. A visit to Sunninghill is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- The joint is cleaned, treated for mould and left to dry.
- 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.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
- Tell us about any water getting in

What we are called out for in Sunninghill
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks. At that point it has to come out.
These are the problems we are asked about most:
- Beads that never stuck properly
- A shower that leaks however often it’s resealed
- Smears and lumps from a botched reseal
- Mould trapped under a layer of silicone
Homes close to Church of St Michael and All Angels include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.
What to look for in a quote
- How the colour is chosen
- Whether the sealant suits the joint
- Who turns up on the day
- How long to leave it before use
