What happens on the day
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start. The work generally takes a few hours, depending on how many layers have to come out. For a job in Southminster, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can
- Let us know about parking restrictions
Getting a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Advice
How we handle remedial sealant in Southminster
A joint that keeps failing normally has a reason. A tray that moves, a worktop that isn’t fixed, the wrong sealant or water getting in elsewhere will beat any new bead. We look for the cause before we reseal. If you have movement joints that have split or pulled away and repeat leaks from the same joint, we can help, whatever the surface.
In a smaller place like Southminster, homes are mostly houses and bungalows rather than flats, from older cottages to newer builds. Sealant and grout wear out here just as they do in a big town.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Questions from Southminster
Do you cover Southminster for remedial sealant?
Yes. We work across London and the South East, and Southminster is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
Is Southminster within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Are you insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
What if the leak isn’t the sealant?
In that case, we tell you what we have found. You may need a plumber or bathroom fitter before any new sealant goes on.
Someone sealed over the old bead. Can you fix it?
Yes. Both layers come out; over-sealing fails because silicone won’t bond to silicone.
For landlords and businesses
If you manage several properties in or around Southminster, several properties can go on one quote. Send us the addresses and the work at each, and photos by email help.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.
What sealant work cannot fix
In fairness, some problems need a different trade:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Tiles that have come away from the wall
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.
Where we work in Southminster
- Botched or over-sealed joints

What affects the cost of remedial sealant
Call for a quick quote. The main things that affect it are:
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
- The number and length of the joints
- How many rooms, windows or areas are involved
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.
What we need to know
Before you ask for a quote, have a think about:
- Roughly how big the job is
- The address or postcode of the job
- The problem you’ve noticed
- Any previous sealing or DIY work
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job.
Why act early in Southminster
Remedial work takes longer than a straight reseal, but not by much: 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 smaller place like Southminster, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
Why Southminster clients choose us
- Anti-fungal silicone where joints get wet
- 20+ years of sealant experience
- White, clear, grey or coloured to suit, where the product allows
- You choose the colour before work begins

Bathrooms and kitchens in Southminster
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For landlords with property near Southminster 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 St Leonard, walls and floors in older homes can move, and sealant and grout show it first.

Common problems we fix in Southminster
Joint depth matters. A bead bonded on three sides, or laid too thick, can’t flex, so it tears when the joint moves. Backing sets the depth and stops that.
These are the problems we’re asked about most:
- Decorators’ caulk around a bath or shower
- Black mould underneath the bead
- Smears and lumps from a botched reseal
- Kitchen joints letting water behind the worktop
Schools such as Southminster Church of England Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
What your quote should include
- Which sealant they’ll use, and why
- How the colour is chosen
- How long the guarantee is
- Who does the work, and how experienced they are

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
