Remedial sealant for homes and businesses in Walberton
Some sealant jobs are not a simple reseal, because someone has already had a go. New sealant over old, smeared beads, unsuitable products and hidden mould all need stripping out. We work on failed movement joints, shrunken worktop sealant and mouldy bath & shower sealant, and the jobs we see most are a shower that leaks however often it’s resealed and a second bead peeling off the first.
Around Walberton, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
A one-year guarantee comes with the work, just as it does everywhere we cover.

FAQs for Walberton
Do you work for landlords with property near Barnham 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.
Will you come out to Walberton?
Yes, Walberton is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What does remedial sealant cost?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or drop us an email and let us know what needs doing and where.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Walberton, along with the rest of our area.
How long does remedial resealing take?
It takes a few hours for a typical bath or shower, longer where several layers have been applied. You will know the timing when we quote.
Can I choose the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before work begins.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- A tray or worktop that needs refixing first
- Failed tanking or loose tiles behind the sealant
- Cracks in the fitting rather than the joint
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before booking.
What we seal
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Failed movement joints
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Expansion joints
How it works
At the end, we look at the finished work together. The visit itself usually takes a few hours for most joints, depending on how much old sealant has to come out, depending on the size of the job. For a village or hamlet like Walberton, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
How to prepare
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints
- Keep pets and children clear of the area while we work

Walberton homes and their sealant
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.
Homes close to St Mary's Church include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. Managing a site like Walberton and Binsted CofE Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes. Letting a property close to Barnham station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Why deal with it now?
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. In a small place like Walberton, 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 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, so you know where you stand.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Act on a lifting corner straight away
- Have loose fittings fixed before resealing
- Use a soft cloth, not a scourer, on silicone
- Ask why a joint failed before redoing it
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.
