Bathroom & kitchen resealing in Newbury, West Berkshire
We cover Newbury for bath, shower, basin, wet room, worktop and sink resealing. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Splits where the tray meets the wall
- Cracked, shrunken or lifting silicone
- Water getting behind the kitchen upstand
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes around two hours for one bath or shower, longer for a whole bathroom and we leave things clean and tidy. For a job in Newbury, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- We start by protecting the area and stripping out the old bead.
- The joint is cleaned, degreased and treated for mould.
- Once it’s dry, any bath is filled so the bead is laid with it at its heaviest.
- We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
- Finally we tidy up and explain the cure time before we leave.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in
- Keep children and pets away from the work area

About our bathroom resealing in Newbury
Sealant is the soft line between a bath, shower or worktop and the wall. When it splits, shrinks or turns black, water gets behind it and into the wall or floor. Our team cut the old bead out completely and lay a new one in anti-fungal sanitary silicone. We are often asked to deal with smears of silicone across the tiles and shrunken sealant along the back of a worktop, across basins & vanity units, kitchen worktops & upstands and wet rooms.
Newbury mixes older houses with estates built more recently, so bathrooms range from long-standing suites to recent refits. Whatever their age, sealant and grout tend to go before anything else.
Your job is guaranteed for a year, as with all our work.

What happens if it’s left?
Leaving a split or mouldy bead only stores up trouble. Once water is behind the bath, it can reach floorboards, panels and the ceiling underneath, turning a small job into a building repair. In a family home in Newbury, a failed seal around a bath or a frame lets water into places you cannot see, like the floor under a bath, the back of a panel or the inside of a wall. Whatever the joint, failed sealant only gets worse.

Newbury: your questions answered
Do you cover Newbury for bathroom resealing?
Yes. We work across London and the South East, and Newbury is part of that. You can call 0345 464 0079 or email us and tell us what needs doing, and we will send you a clear quote.
I let a flat near Newbury station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Is it OK to put new sealant on top of the old bead?
No, never. Sealing over the top looks fine for a few weeks, then lifts. Every trace of the old bead is removed first.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
Can you do several jobs on one visit?
Yes, we can. More than one area can go on one quote.
How do I get a quote for bathroom resealing in Newbury?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or send us an email with a short description of the job.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

Can I do it myself?
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.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Do not leave water standing on kitchen joints
- Give the silicone its full cure time
- Do not let bottles sit on the bead
- Use gentle cleaners on the silicone
Check the sealant now and then. A small split or a corner lifting is easy to spot, and if anything looks wrong, just phone 0345 464 0079 or email us.
Watch for the early signs: a corner lifting, a gap behind the bead, a dark line under the silicone or a damp patch on the ceiling below. Any of these means the joint needs attention.

Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
We work for landlords and agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Bathrooms and kitchens in Newbury
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings. Newbury 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 St Nicolas C.E. Junior 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. Homes close to St Nicolas Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. For landlords with property near Newbury station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

What the job involves on each surface
Sinks & splashbacks
Splashbacks in glass, tile or acrylic meet the worktop in a long joint. We renew it in clear, white or a matched colour.
Baths
Baths move more than any other fitting, so it’s filled with water before the bead goes on. That way the joint is laid with the bath at its heaviest and is not stretched when it’s used.
