Different surfaces, different methods
Movement & expansion joints
A movement joint must be able to stretch. We remove the failed sealant, fit backing and reseal.
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. That needs refixing before resealing, and we’ll tell you if we find it.
Remedial sealant in Radnage
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. If you have a shower that leaks however often it’s resealed and worktop sealant that has shrunk and split, we can put it right, whatever the surface.
In a village or hamlet like Radnage, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.
Every job is covered by our one-year guarantee.

What we do, step by step
At the end, we look at the finished work together. The visit itself usually takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on the size of the job. In a small place like Radnage, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we find out how and where the joint has failed.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- Finally we finish the joint and talk you through what we found.
How to prepare
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Sealant in an older building that needs testing for asbestos first
- Failed tanking or loose tiles behind the sealant
- Plumbing leaks behind walls or under trays
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
Joints and surfaces we work on
- Expansion joints
- Botched or over-sealed joints
- Failed movement joints
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant

Do you need remedial sealant in Radnage?
One of the commonest remedial jobs is sealant on top of sealant. New silicone cannot stick to the old bead, so the new layer peels, and damp and mould settle between them.
Signs it’s time to call us include:
- Sealant applied over old sealant that has lifted
- Movement joints that have split or pulled away
- Caulk or the wrong sealant used in a wet area
- Worktop sealant that has shrunk and split
If you look after a building such as Radnage Church of England Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Why act early in Radnage
Repeat failures have a cause. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. In a small place like Radnage, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear quote before work begins.

What remedial sealant looks like in Radnage
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
Homes close to Church of St Mary include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. Rented homes near Saunderton station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.
