Remedial sealant in Lower Green
Movement and expansion joints fail when the sealant cannot stretch. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. We work on mouldy bath & shower sealant, botched or over-sealed joints and expansion joints, and people most often call us about a shower that leaks however often it’s resealed and products that weren’t meant for the joint.
For a small place like Lower Green, remedial sealant is planned like any other job: the journey and access are simply agreed in advance. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

Remedial sealant in Lower Green: local notes
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.
Around Lower Green, as everywhere, remedial sealant is only as good as the preparation behind it.

When to call us in Lower Green
One of the commonest remedial jobs is sealant on top of sealant. Silicone does not bond to silicone, so the new layer peels, and damp and mould settle between them.
The problems people generally mention when they call include:
- Over-sealed joints coming away
- Leaks that keep coming back after resealing
- Floor or wall movement joints that have failed
- Mould trapped under a layer of silicone
Homes close to Church of St John the Evangelist include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.
What to look for in a quote
- How long to leave it before use
- Who turns up on the day
- Whether they seal over old material or remove it
- What product goes in the joint
What happens if it’s left?
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. The layers have to come out. Older cottages and farmhouses around Lower Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.
What you get with us
- One-year guarantee on every job
- More than 20 years in sealant work
- Arbo and Everbuild products
- Sealant colour chosen to suit

Different surfaces, different methods
Mouldy bath & shower sealant
Black mould inside the bead won’t scrub out. All of it comes out, and the joint is treated and dried before anti-fungal sanitary silicone goes in.
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. We strip it, degrease the joint and reseal in a colour to suit.
Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Landlords, agents and businesses in Lower Green
We also work for property managers and facilities teams. We can quote a run of properties together.

How the visit works
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for a typical bath or shower, longer where several layers have been applied. For a village or hamlet like Lower Green, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking the joint for movement, leaks and the reason it failed.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Let us know about parking restrictions
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work
