What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours, depending on how many layers have to come out and we leave things clean and tidy. For a village or hamlet like Cold Ash, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Mention if the joints have been sealed before
- Clear the area around the work
- Tell us if parking is tricky

Advice
About our remedial sealant in Cold Ash
Water on the floor doesn’t always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that is what we find, we’ll tell you rather than reseal something that will not fix it. We work on leaking tray & enclosure joints, failed movement joints and botched or over-sealed joints, and common reasons people get in touch are wide, uneven beads that look worse than the old ones and products that weren’t meant for the joint.
Being in a small place like Cold Ash makes no difference to the job itself: the journey and access are simply agreed in advance. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.
Whatever the size of the job, it’s backed by our one-year guarantee in Cold Ash and across West Berkshire.

Aftercare tips
Aftercare is simple:
- Keep the room well ventilated
- Have loose fittings fixed before resealing
- Check ceilings under showers for marks
- Never fill a movement joint with mortar or grout
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
Warning signs: 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.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Tiles that have come away from the wall
- A bath, tray or worktop that moves until it’s properly fixed
- Plumbing leaks behind walls or under trays
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

What the job involves on each surface
Windows & doors
Some leaks around windows come from the wall or the window itself. If the frame joint is not the cause, we will say so.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated.
Why deal with it now?
A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Around Cold Ash, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Bathrooms and kitchens in Cold Ash
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.
If you let a flat or house near Thatcham station, botched sealant from a previous quick fix is easier to strip out between tenants. Managing a site like Cold Ash St Mark's C.E. 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. If you live in an older home near St. Mark's Church, walls and floors in older homes can move, and sealant and grout show it first.

Questions from Cold Ash
Can you help a landlord with a rental near Thatcham station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Is Cold Ash within the area you cover?
Yes, Cold Ash is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you fix expansion and movement joints?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, and reseal with a flexible product.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Do you guarantee remedial jobs?
Yes. You get our 12-month guarantee, and we’re ARBOMaster approved.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
What if the leak isn’t the sealant?
We’ll tell you. A cracked tray, faulty valve or leaking waste needs a different trade, and we will not reseal for the sake of it.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
