Remedial sealant for homes and businesses in South Harefield
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. We are often asked to deal with sealant peeling off a dusty or damp surface and floor or wall movement joints that have failed, on mouldy bath & shower sealant, leaking tray & enclosure joints and shrunken worktop sealant.
Being in a small place like South Harefield makes no difference to the job itself: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

How it works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere as small as South Harefield, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Always have old sealant cut out, not covered
- Keep movement joints clear of mortar and paint
- Keep the room well ventilated
- Deal with small splits early
Go easy on the new sealant: no scraping, scouring pads or harsh chemicals.
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. Each one is worth getting looked at.
What the job involves on each surface
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We work carefully to avoid adding to it, and point out any existing damage.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out.
When to call us in South Harefield
Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.
People normally contact us after spotting one of these:
- Beads that never stuck properly
- Repeat leaks from the same joint
- Wide, uneven beads that look worse than the old ones
- Movement joints that have split or pulled away
For site and facilities teams at buildings such as Harefield Infant School, 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.

South Harefield questions
Is South Harefield within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Denham station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Someone sealed over the old bead. Can you fix it?
Yes. We remove every layer; over-sealing fails because silicone will not bond to silicone.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
Do you have insurance?
Yes. We are fully insured.
Can old silicone be taken off without scratching the tiles?
Yes, with care. We cut and lift the old sealant with tools suited to the surface, then clean off the residue. We point out any damage that is already there.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
What happens if it’s left?
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. Where a wall is exposed, as many are in small places like South Harefield, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

What remedial sealant looks like in South Harefield
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
Homes close to Church of St Mary the Virgin include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you let a flat or house near Denham station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
