Remedial sealant in Dedworth
Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all need stripping out before the joint can be done properly. If you have sealant applied over old sealant that has lifted and smears and lumps from a botched reseal, we can help, on shrunken worktop sealant, expansion joints and mouldy bath & shower sealant alike.
In a smaller place like Dedworth, homes are mostly houses and bungalows rather than flats, some older and some much newer. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
You are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

Remedial sealant around Dedworth
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. Dedworth has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
Schools such as Dedworth Green First School are buildings too, and 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. If you live in an older home near All Saints Church, walls and floors in older homes can move, and sealant and grout show it first.

The process
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. In a smaller place like Dedworth, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Keep children and pets away from the work area
- Mention if the joints have been sealed before

Advice
Common problems we fix in Dedworth
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
People generally contact us after spotting one of these:
- A second bead peeling off the first
- Movement joints that have split or pulled away
- Wide, uneven beads that look worse than the old ones
- Beads that never stuck properly
Letting a property close to Windsor & Eton Central station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

Surface by surface
Worktops & kitchens
Kitchen joints hold grease and residue, so we spend extra time cleaning before resealing.
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. We remove it all and clean back to sound surfaces.
Why act early in Dedworth
DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. Around Dedworth, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Do not wait for a small gap to become a leak
- Report a tray that rocks or a worktop that lifts
- Keep movement joints clear of mortar and paint
- Air the bathroom so the sealant can dry
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.
If a joint has failed more than once, stop resealing it. Get the cause found first, otherwise the next attempt will fail too.

Honest limits
New sealant can’t fix everything, and we will tell you before we start. Sealant won’t put right:
- Movement from fittings that are not supported
- Failed tanking or loose tiles behind the sealant
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed

Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Yes. We cut out all the layers and clean off the film, then the joint is resealed once.

That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
How long does the work take?
A little longer than a standard reseal. Most jobs take a few hours.
What if the leak is not the sealant?
Then we explain what we have found. You may need a plumber or bathroom fitter.
