Your questions about remedial sealant in Southend
Can you help a landlord with a rental near Portchester station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Will you come out to Southend?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How long will it take to strip and reseal the joint?
Longer than a simple reseal, because every layer has to come out. For most joints, it’s a few hours, and we confirm the time with your quote.
Someone resealed my shower and it’s leaking again. Can you help?
Yes, generally. First we check whether the leak is the sealant at all, then the joints are stripped and resealed.
Does remedial work come with a guarantee?
Yes. You get our 12-month guarantee, and we are ARBOMaster approved.
Can you match the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
What happens if the problem is the tray or the plumbing?
Then we explain what we’ve found. A plumber or fitter may be needed before any new sealant goes on.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Remedial sealant in Southend, done properly
If a joint has been resealed and is leaking again, it’s worth a proper look. It helps to have pictures when you phone 0345 464 0079 or drop us an email. We work on failed movement joints, shrunken worktop sealant and leaking tray & enclosure joints, and the jobs we see most are sealant applied over old sealant that has lifted and floor or wall movement joints that have failed.
In a village or hamlet like Southend, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.
Big or small, you get the same one-year guarantee.

Why deal with it now?
DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful removal is most of a remedial job. Older cottages and farmhouses around Southend can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
Why choose Mr Mastic in Southend
- Colour picked to suit the job
- Any old sealant cut out fully, not covered over
- Colour agreed with you before work begins
- ARBOMaster approved applicator
DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, 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.

How we quote for remedial sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether there’s mould to deal with
- How much there is to do
- Which sealant suits the joint
- How easy the joints are to reach
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and send you a clear quote before any work starts.
Helping us quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- The problem you’ve noticed
- The rough size of the job
- Pictures of the joints, sent by email
- If someone has resealed it before
Every job is quoted individually. Just ring 0345 464 0079 or email us with the details, and photos are welcome.
Different surfaces, different methods
Movement & expansion joints
A sealant stuck to the back of the joint cannot stretch. Backing rod or bond-breaker tape prevents it, letting the sealant flex between the two faces.
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. It’s cut out, degreased and resealed in a colour to suit.
How it works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours, depending on how many layers have to come out. Somewhere as small as Southend, access is often the only tricky part. 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.
- 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
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints

When something else is needed
New sealant can’t fix everything, and we will tell you before work begins. It will not solve:
- A tray or bath that’s cracked
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Older mastics that may need an asbestos check before removal
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.
Joints and surfaces we work on
- Expansion joints
- Failed movement joints
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Botched or over-sealed joints
- Mouldy bath & shower sealant
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Find out why the sealant failed first
- Air the bathroom so the sealant can dry
- Always have old sealant cut out, not covered
- Report a tray that rocks or a worktop that lifts
Give the new sealant its full cure time: usually around 24 hours, or as long as we advise.
Do not keep resealing the same joint. Have someone find out why, otherwise the next attempt will fail too.
Remedial sealant in Southend: local notes
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Managing a site like Newtown Soberton Infant School? Then we reseal washrooms and kitchens in schools and businesses as well as homes. If you let a flat or house near Portchester station, a joint that keeps failing is best fixed properly while the property is empty. 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.
