Remedial sealant in Maplehurst, done properly
Movement and expansion joints fail when the sealant can’t stretch. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. Typical jobs include products that weren’t meant for the joint and a shower that leaks however often it’s resealed, across mouldy bath & shower sealant, expansion joints and failed movement joints.
For a small place like Maplehurst, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

Your questions about remedial sealant in Maplehurst
Do you cover smaller places like Maplehurst?
Yes. Maplehurst is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Christs Hospital station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Maplehurst, along with the rest of our area.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is remedial work guaranteed?
Yes. Remedial work carries the same 12-month guarantee as all our work.
What affects the cost of remedial sealant
The price is agreed before any work begins. It’s based on:
- Working hours on commercial sites
- Any mould that needs treating
- Whether old sealant or filler has to be cut out
- The type of sealant required
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we will go through it with you.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
- Where the property is
- The problem you’ve noticed
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.
How to look after the new joints
Looking after new joints is easy:
- Keep movement joints clear of mortar and paint
- Run the fan after every shower
- Keep an eye on the ceiling below the bathroom
- Keep bleach and abrasives off the bead
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.

Why act early in Maplehurst
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and the residue left behind stops the next bead bonding. Careful removal is most of a remedial job. Around Maplehurst, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

How it works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere as small as Maplehurst, 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.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Clear items away from the joints we are working on
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work

Common problems we fix in Maplehurst
Using the wrong product is a common cause: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. None of them last.
If you can see any of these, it’s time to have the joints looked at:
- Beads that never stuck properly
- Torn expansion joints
- Sealant applied over old sealant that has lifted
- Thick, messy sealant smeared over tiles
For landlords with property near Christs Hospital station, botched sealant from a previous quick fix is easier to strip out between tenants.
Questions to ask before booking
- Whether VAT is included
- What happens if they find a problem under the old sealant
- The length of the guarantee
- When the joint can take water or movement
Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
Remedial sealant around Maplehurst
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.
Managing a site like St Andrew's CofE Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes. Homes close to The Parish Church of St Andrew include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.
