Remedial sealant around Westergate
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Managing a site like Aldingbourne Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Rented homes near Barnham station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

What affects the cost of remedial sealant
We do not publish a price list. What we look at:
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- The number of rooms or windows
- Whether the work is at height
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- Whether it’s a home or a business
- Photos by email, if that is easy
- The rough size of the job
- Any previous sealing or DIY work
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
What the job involves on each surface
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. We strip it, degrease the joint and reseal.
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing stops that, so the sealant grips the two sides only.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Check trays and worktops do not move
- Get the cause of a repeat leak found before resealing
- Air the bathroom so the sealant can dry
- Deal with small splits early
Go easy on the new sealant: a mild cleaner and a soft cloth, with no blades or scourers.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
Westergate: your questions answered
Do you work for landlords with property near Barnham station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you come out to Westergate?
Yes. Westergate is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
My shower still leaks after a reseal. Can you sort it?
Yes. There’s generally a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Westergate, along with the rest of our area.
How much does remedial sealant cost in Westergate?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or send us an email with a short description of the job.
Can you match the sealant colour?
Most of the time, yes. We’ll explain which colours are available and agree one before any work starts.
Landlord and commercial work in Westergate
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
What happens if it’s left?
Mould under a bead can’t be reached by cleaning. The layers have to come out, and the joint treated and dried before resealing. Around Westergate, 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.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

What we can’t put right
In fairness, some problems need a different trade:
- Older mastics that may need an asbestos check before removal
- A tray or bath that’s cracked
- A tray or worktop that needs refixing first

How it works
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a typical bath or shower, longer where several layers have been applied. For a job in Westergate, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Tell us about any water getting in
- Keep children and pets away from the work area
- Tell us if parking is tricky
