Lunsford Remedial Sealant
Remedial sealant for Lunsford, by sealant specialists with 20+ years’ experience. 180+ five-star Google reviews and a 4.9 rating.

What happens if it’s left?
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. Removal is the only way to get at it, so the joint can be treated and resealed. Around Lunsford, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.

How we handle remedial sealant in Lunsford
The wrong product in the wrong joint will not last, however tidy it looks. We take it out and use a sealant made for that joint. We work on leaking tray & enclosure joints, shrunken worktop sealant and expansion joints, and the jobs we see most are beads that never stuck properly and decorators’ caulk around a bath or shower.
Homes around Lunsford range from older cottages to more recent houses. Older homes can move a little with the seasons, which is hard on tired sealant and rigid grout.
There’s a 12-month guarantee on every job, whatever its size.

How the visit works
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before any work starts. Most jobs take a few hours, depending on how many layers have to come out. Parking around Lunsford is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Mention any tricky access
- Try not to wet indoor joints just before the visit

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

Common problems we fix in Lunsford
Using the wrong product is a common cause: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. Each fails in its own way.
People generally contact us when they notice something like this:
- Kitchen joints letting water behind the worktop
- Beads that never stuck properly
- Torn expansion joints
- Wide, uneven beads that look worse than the old ones
For an older house near a landmark such as Church of the Holy Trinity, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Can you do remedial sealant in Lunsford?

Where is Mr Mastic based?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Can you match the sealant colour?
Most of the time, yes. We’ll tell you which colours the right product comes in.
Can you remove sealant that’s been put over old sealant?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s what makes the new bead last.
Lunsford homes and their sealant
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.
For landlords with property near New Hythe station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Schools such as Lunsford Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
When something else is needed
We won’t take on work that won’t last, so here’s what sealant can’t put right:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- A tray or worktop that needs refixing first
- Tiles that have come away from the wall
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before booking.
Surfaces we seal
- Failed movement joints
- Mouldy bath & shower sealant
- Expansion joints

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Use a soft cloth, not a scourer, on silicone
- Keep the room well ventilated
- Never seal over old silicone
- Report a tray that rocks or a worktop that lifts
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
Warning signs: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.
