What affects the cost of remedial sealant
The quote reflects the job in front of us. We look at:

Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Photos by email are helpful but not essential. Please mention:
- If someone has resealed it before
- Photos by email, if that is easy
- Any access issues, like height or stairs
- Where the property is
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we will take it from there.
Remedial sealant in Wilmington, done properly
The wrong product in the wrong joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. We work on expansion joints, shrunken worktop sealant and mouldy bath & shower sealant, and common reasons people get in touch are a second bead peeling off the first and kitchen joints letting water behind the worktop.
In a village or hamlet like Wilmington, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
You get a one-year guarantee, the same in Wilmington as everywhere else we work.

Questions from Wilmington
Is Wilmington in your area for remedial sealant?
Yes. Our work covers London and the South East, and Wilmington is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Do you work for landlords with property near Crayford 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 we start.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can you take off two layers of silicone?
Yes. Both layers come out; new silicone does not bond to old silicone, which is why over-sealing fails.
How long will it take to strip and reseal the joint?
The number of joints and layers decides it. You’ll have a timescale before any work begins.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you match the sealant colour?
In most cases you can choose. We’ll explain which colours are available and agree one before work begins.
How it works
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take 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.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
How to prepare
- Clear items away from the joints we’re working on
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions

Related advice
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Leave it or put it right?
Ripping out a bathroom is not generally needed. When the fittings are sound, stripping and resealing the joints is often enough. If they’re not, we’ll tell you. Around Wilmington, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Bathrooms and kitchens in Wilmington
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.
Homes close to St Barnabas include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. Letting a property close to Crayford station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. If you look after a building such as Wilmington Grammar School for Girls, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

What the job involves on each surface
Mouldy bath & shower sealant
Mould that has grown into silicone does not clean out for good. The sealant is cut out completely, the joint treated with a mould remover and dried before anti-fungal sanitary silicone goes in.
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, including the screen profile and tray edges.
Aftercare tips
So the new joints stay in good condition:
- Keep movement joints clear of mortar and paint
- Get the cause of a repeat leak found before resealing
- Report a tray that rocks or a worktop that lifts
- Never seal over old silicone
Don’t let anyone seal over it later. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
