- A tray or worktop that needs refixing first
- Tiles that have come away from the wall
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before you book.
Surfaces we seal
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Expansion joints
- Botched or over-sealed joints
- Failed movement joints
- Shrunken worktop sealant
About our remedial sealant in Eastergate
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. Only then can new sealant bond. Typical jobs include worktop sealant that has shrunk and split and over-sealed joints coming away, across failed movement joints, expansion joints and mouldy bath & shower sealant.
Around Eastergate, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
All our work is covered by our 12-month guarantee.

Eastergate: your questions answered
Is Eastergate within the area you cover?
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 work for landlords with property near Barnham station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do you have insurance?
Yes. We are fully insured for every job we do.
How long will it take to strip and reseal the joint?
A little longer than a standard reseal. Most jobs take a few hours.
What does remedial sealant cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Eastergate.
Can you strip sealant from an acrylic tray safely?
Yes, with care. The old bead is cut and lifted with tools that suit the surface, and the residue is cleaned away. We point out any damage that is already there.
Do I have to be there?
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.
What happens on the day
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a typical bath or shower, longer where several layers have been applied for a typical job. In a small place like Eastergate, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property

Advice
Signs you need remedial sealant in Eastergate
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, so it starts lifting sooner than it should.
Most people get in touch when they notice something like this:
- A shower that leaks however often it’s resealed
- Black mould underneath the bead
- Over-sealed joints coming away
- Wide, uneven beads that look worse than the old ones
In the older streets around St George's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Questions to ask before booking
- Who turns up on the day
- What happens if the job turns out different
- What the quote includes, VAT included or not
- Whether you can choose the colour
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Act on a lifting corner right away
- Air the bathroom so the sealant can dry
- Never seal over old silicone
- Report a tray that rocks or a worktop that lifts
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. If anything changes, just call 0345 464 0079 or drop us an email.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into whatever is behind or below. Early action keeps it to a sealant job.

What remedial sealant looks like in Eastergate
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.
For site and facilities teams at buildings such as Eastergate CofE Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. Rented homes near Barnham station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.

Leave it or put it right?
Mould under a bead cannot be reached by cleaning. Removal is the only way to get at it, so the joint can be treated and resealed. In a small place like Eastergate, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
