Remedial sealant in Cudham: local notes
Most of the South East has hard water, 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 Chelsfield station, botched sealant from a previous quick fix is easier to strip out between tenants. Managing a site like Cudham Church of England Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

FAQs for Cudham
Is Cudham within the area you cover?
Yes, Cudham is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Chelsfield station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Does remedial work come with a guarantee?
Yes, with our 12-month guarantee. Where we’ve flagged another fault, it needs fixing for the joint to last.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you when we finish.
Where is Mr Mastic based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can you remove sealant that is been put over old sealant?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s what makes the new bead last.
What does remedial sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Looking after it afterwards
So the new joints stay in good condition:
- Report a tray that rocks or a worktop that lifts
- Always have old sealant cut out, not covered
- Use a soft cloth, not a scourer, on silicone
- Check ceilings under showers for marks
Don’t let anyone seal over it later. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
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 affects the cost of remedial sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
- How easy the joints are to reach
- Whether there’s mould to deal with
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.
Asking for a quote
Before you ask for a quote, have a think about:
- Where the property is
- Any access issues, like height or stairs
- Whether it’s a home or a business
- If someone has resealed it before
Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job, and we’ll come back to you with a quote.

The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours for a typical bath or shower, longer where several layers have been applied. For a village or hamlet like Cudham, 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.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
Getting ready for the visit
- Keep children and pets away from the work area
- Tell us about any water getting in
- On commercial sites, let us know about site rules

Related advice
Signs you need remedial sealant in Cudham
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould, faster where ventilation is poor. At that point it has to come out.
People usually contact us after spotting one of these:
- Products that weren’t meant for the joint
- A second bead peeling off the first
- Sealant that came away because the surface wasn’t prepared
- A shower that leaks however often it’s resealed
In the older streets around Church of St Peter and St Paul, older homes can move a little, which is hard on rigid grout and tired sealant.
Questions to ask before you book
- What the quote includes, VAT included or not
- Which colour the sealant will be
- Whether the sealant suits the joint
- Who turns up on the day
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
