Remedial sealant in Lunsford's Cross
If a joint fails again and again, something is causing it. A tray that moves, a worktop that is not fixed, the wrong sealant or water getting in elsewhere will beat any new bead. We look for the cause before we reseal. We work on leaking tray & enclosure joints, failed movement joints and expansion joints, and common reasons people get in touch are beads that never stuck properly and mould trapped under a layer of silicone.
Around Lunsford's Cross, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.
Our work is backed for twelve months.

Why act early in Lunsford's Cross
Remedial work takes longer than a straight reseal, but rarely a lot: it takes a few hours for most joints, depending on how much old sealant has to come out. It’s far less disruption than resealing the same joint again and again. In a small place like Lunsford's Cross, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

FAQs for Lunsford's Cross
Will you come out to Lunsford's Cross?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Lunsford's Cross for remedial sealant?
Yes. Our work covers London and the South East, and Lunsford's Cross is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear price.
Where is Mr Mastic based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you offer different sealant colours?
Yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.
How long will it take to strip and reseal the joint?
Allow a few hours, depending on how many layers have to come out. You will know the timing when we quote.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. There’s usually a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
What we cannot put right
We’ll always be straight with you, so here’s what new sealant will not do:
- Tiles that have come away from the wall
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A leaking trap, valve or supply pipe
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
What we seal
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Failed movement joints
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Expansion joints
Signs you need remedial sealant in Lunsford's Cross
Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.
Look out for these signs:
- A shower that leaks however often it’s resealed
- Caulk or the wrong sealant used in a wet area
- Sealant peeling off a dusty or damp surface
- Thick, messy sealant smeared over tiles
If you look after a building such as Ninfield Church of England Primary 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.

Remedial sealant in Lunsford's Cross: local notes
Lunsford's Cross is within about 3 miles of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. 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.

What affects the cost of remedial sealant
Jobs vary more than people expect. The main factors:
- How easy the joints are to reach
- The number and length of the joints
- The product the joint needs
- How many rooms, windows or areas are involved
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.
Asking for a quote
There’s no need for technical detail. Just tell us:
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
- A few photos by email, if you can
- How we’d reach the joints
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, 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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Different surfaces, different methods
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. We strip it, degrease the joint and reseal.
Movement & expansion joints
Joints filled with mortar, grout or rigid filler can’t move. Where it can be raked out, we replace it with flexible sealant.
How it works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a typical bath or shower, longer where several layers have been applied, and the area is left clean. For a village or hamlet like Lunsford's Cross, 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.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height
