Remedial sealant & repairs in Wilmington, East Sussex
Our applicators work in Wilmington on removing failed, mouldy or leaking sealant and putting it right. Old material cut out, joints cleaned and sealed neatly.

Remedial sealant for homes and businesses in Wilmington
Remedial jobs in Wilmington generally fall into a few patterns: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. We work on leaking tray & enclosure joints, expansion joints and shrunken worktop sealant, and the jobs we see most are kitchen joints letting water behind the worktop and leaks that keep coming back after resealing.
Somewhere as small as Wilmington, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
You get a one-year guarantee, the same in Wilmington as everywhere else we work.

Why deal with it now?
DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. In a small place like Wilmington, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Never fill a movement joint with mortar or grout
- Never seal over old silicone
- Check trays and worktops don’t move
- Keep an eye on the ceiling below the bathroom
Where we have pointed out another fault, have it put right, or the new joint may fail again.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.
Wilmington homes and their sealant
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.
If you look after a building such as Willingdon Community School, we reseal washrooms and kitchens in schools and businesses as well as homes. Homes close to St Mary and St Peter's Church include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. Letting a property close to Berwick (Sussex) station? Then a joint that keeps failing is best fixed properly while the property is empty.

How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most joints, depending on how much old sealant has to come out. Somewhere like Wilmington needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive

FAQs for Wilmington
Can you help a landlord with a rental near Berwick (Sussex) station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Will you come out to Wilmington?
Yes. Wilmington is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we are using and why.
Can you take off two layers of silicone?
Yes. We cut out all the layers and clean off the film, then the joint is resealed once.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Surface by surface
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant won’t fix it. We say so rather than reseal.
Over-sealed & botched joints
Every layer has to come out, and silicone residue is cleaned off the tiles too. New sealant needs a fully clean surface.
Work for landlords, hotels and businesses
We work for landlords and agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
When something else is needed
We’d rather tell you now than do work that will not last, so these are the limits:
- Older mastics that may need an asbestos check before removal
- Movement from fittings that aren’t supported
- Leaks from a shower valve, waste or pipework (a plumber’s job)
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before booking.
