Why it’s worth doing now in Painters Ash
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. Homes in smaller places like Painters Ash can face more weather, and failed outside joints let damp into walls. 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: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Different surfaces, different methods
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We work carefully to avoid adding to it, and tell you about any damage we find.
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, including the screen profile and tray edges.
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- A tray or worktop that needs refixing first
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A cracked shower tray or bath (that needs repair or replacing)
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.
Surfaces we seal
- Leaking tray & enclosure joints

What remedial sealant looks like in Painters Ash
Painters Ash is within about 3 miles of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. 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.
Homes close to Church of All Saints include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. If you let a flat or house near Ebbsfleet International station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Signs it’s time to call us include:
- Smears and lumps from a botched reseal
- Sealant peeling off a dusty or damp surface
- Floor or wall movement joints that have failed
- Mould trapped under a layer of silicone

Questions from Painters Ash
Do you work for hotels and guest houses in Painters Ash?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Is Painters Ash within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
How long before the joint can be used?
It depends on the product. Before we leave, we will tell you the cure time.
My shower still leaks after a reseal. Can you sort it?
Yes. There’s generally a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
The process
At the end, we look at the finished work together. The work normally takes a few hours, depending on how many layers have to come out, depending on the amount of work. A visit to Painters Ash is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- We use the right backing and sealant for any joint that moves.
- Finally we finish the joint and talk you through what we found.
Before we arrive
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints
