- Wide, uneven beads that look worse than the old ones
How we handle remedial sealant in Marehill
A joint that keeps failing normally has a reason. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. We look for the cause before we reseal. If you have kitchen joints letting water behind the worktop and sealant applied over old sealant that has lifted, we can help, whatever the surface.
Being in a small place like Marehill makes no difference to the job itself: it just means planning the journey and access beforehand. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
Your job is guaranteed for a year, as with all our work.

Remedial sealant around Marehill
Hard water is the norm across most of the South East, which leaves limescale 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 St Mary's Church of England Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. Homes close to Wiggonholt Church include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Do you need remedial sealant in Marehill?
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, faster where ventilation is poor. At that point it has to come out.
The problems people normally mention when they call include:
- Black mould underneath the bead
- Worktop sealant that has shrunk and split
- Over-sealed joints coming away
- Wide, uneven beads that look worse than the old ones
Rented homes near Pulborough station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

How the visit works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for most joints, depending on how much old sealant has to come out from start to finish. Somewhere like Marehill needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- You get the cure time and our view on why the joint failed.
How to prepare
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
- Clear the area around the work

What the job involves on each surface
Windows & doors
Frames resealed over the top end up with hard, layered mastic. All of it is cut out and the frame and wall cleaned.
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. Both are checked before we reseal.
Marehill questions
Is Marehill in your area for remedial sealant?
Yes. We work across London and the South East, and Marehill is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
Do you work for landlords with property near Pulborough station?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
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.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings, 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?
We’ll tell you. If it’s a cracked tray, a failed valve or a leaking waste, resealing won’t fix it, so we will not pretend it will.
Will there be a smell?
There can be a smell while the sealant cures. Opening a window helps.
Can I add another job to the visit?
Yes. Just list everything you need.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
What sealant work can’t fix
It helps to know what we cannot do:
- Older mastics that may need an asbestos check before removal
- Water damage behind tiles that needs a tiler
- A bath, tray or worktop that moves until it’s properly fixed
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.
What we seal
- Shrunken worktop sealant
- Expansion joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Failed movement joints
For landlords and businesses
If you manage several properties in or around Marehill, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Why it’s worth doing now in Marehill
Adding more sealant is the usual quick fix, and it rarely works. It can’t bond to what’s underneath, so the leak carries on and there’s now more to remove. In a small place like Marehill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Combining jobs into one visit normally makes better use of the time than several visits. We will send you a clear quote for the lot.
