- A messy, uneven bead from a previous reseal
- Gaps between the worktop and the wall
- Water getting behind the bath panel
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Wait for the cure time we give you
- Check the joints every few months for splits or lifting
- Keep the fan on for a while after bathing
- Stick to a soft cloth and a mild cleaner
Keep water off the new bead until it has cured, which is generally around 24 hours. After that, a quick wipe after showering helps keep it clean.
Small signs come before a leak: lifting ends, gaps, dark shadows under the bead or a stain downstairs. If you spot one, it’s time to reseal.
Bathroom resealing in Donnington
The secret of a lasting bead is the preparation. Every bit of old silicone comes out, down to the thin film left on the tiles, after which the joint is degreased and any mould treated. Only once it’s dry does the new bead go on. We are often asked to deal with gaps where the bath or tray has moved and failed sealant on the screen profile, across baths, shower trays & enclosures and wet rooms.
In a smaller place like Donnington, homes are mostly houses and bungalows rather than flats, from older cottages to newer builds. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

Donnington: your questions answered
Do you work in hotels near Donnington?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Is Donnington within the area you cover?
Yes, Donnington is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
How long does the new silicone need before I use the shower?
We give you the cure time before we leave, and it’s usually around 24 hours. Using it sooner can damage the bead.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Is it OK to put new sealant on top of the old bead?
No. Fresh silicone cannot stick to the old bead, so it lifts and traps water and mould underneath. All the old sealant comes out first.
What colours of sealant can you use?
There’s a choice: clear, white and colours chosen to suit the room. We can help you pick when we quote.
How it works
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes half a day or less for one room, longer when the kitchen is included in most cases. In a smaller place like Donnington, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First, each joint is checked for movement and signs of water.
- Every trace of the old bead is removed, including the thin smear on the tiles.
- The joint is cleaned, degreased and treated for mould.
- With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
- We tool the bead to a neat finish and give you the cure time, normally around 24 hours.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed

Advice
Why deal with it now?
A clean new bead makes a room look cared for, which helps when a home is being let or put on the market. A smeared, uneven DIY bead does the opposite, and it’s harder to put right later. Around Donnington, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re unsure, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

For landlords and businesses

We work for letting agents and landlords as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Surface by surface
Kitchen worktops & upstands
Laminate worktops swell if water gets into the core. A sound joint along the back edge stops that, as long as the worktop itself is firmly fixed.
Sinks & splashbacks
Around the sink, we use a product suited to kitchens, including a food-safe sealant where that’s needed. The joint is laid neatly so it’s easy to wipe.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- A tray or bath that is cracked through
- Failed grout lines across the wall
- Loose or hollow tiles, or failed tanking behind them
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.
What we seal
- Sinks & splashbacks
- Basins & vanity units

Common problems we fix in Donnington
Not every tube in the shop is meant for a shower. Decorators’ caulk and all-purpose sealants are not made for constant wetting, so they crack, discolour or grow mould quickly. Wet areas call for a sanitary silicone with an anti-fungal additive.
Keep an eye out for these signs:
- Water getting behind the kitchen upstand
- Water getting behind the bath panel
- Failed sealant on the screen profile
- Black mould in the silicone that won’t clean off
Managing a site like Larkrise Primary School? Then 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.

What bathroom resealing looks like in Donnington
Donnington 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. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
If you live in an older home near St Alban the Martyr, older homes can move a little, which is hard on rigid grout and tired sealant. Rented homes near Oxford station change hands often, and mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets.
