Remedial sealant in Mowshurst
Two decades of sealant work means we recognise most failures quickly. We are ARBOMaster approved and fully insured, and every remedial job comes with a 12-month guarantee. We work on botched or over-sealed joints, leaking tray & enclosure joints and mouldy bath & shower sealant, and common reasons people get in touch are decorators’ caulk around a bath or shower and kitchen joints letting water behind the worktop.
Around Mowshurst, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
There’s a 12-month guarantee on every job, whatever its size.

How the visit works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied from start to finish. For a village or hamlet like Mowshurst, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work

Common questions in Mowshurst
Is Mowshurst within the area you cover?
Yes. Mowshurst is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work in hotels near Mowshurst?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
How long before the joint can be used?
Cure times vary by product. Before we leave, we will tell you the cure time.
What does remedial sealant cost?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or drop us an email and tell us what needs doing and where.
Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few photos.
What if the leak isn’t the sealant?
We will tell you. A cracked tray, faulty valve or leaking waste needs a different trade, and we will not reseal for the sake of it.
Can you take off two layers of silicone?
Yes. We remove every layer; over-sealing fails because silicone won’t bond to silicone.
Why act early in Mowshurst
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. The layers have to come out, and the joint treated and dried before resealing. Where a wall is exposed, as many are in small places like Mowshurst, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Mowshurst homes and their sealant
There are hotels and other places to stay in and around Mowshurst. Hotel bathrooms are part of our work as well as homes, and can be done room by room. 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.
Letting a property close to Edenbridge station? Then a joint that keeps failing is best fixed properly while the property is empty. Managing a site like Edenbridge Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Homes close to Church of St Peter and St Paul include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

Landlords, agents and businesses in Mowshurst
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
How to look after the new joints
So the new joints stay in good condition:
- Check trays and worktops do not move
- Keep the room well ventilated
- Never fill a movement joint with mortar or grout
- Never seal over old silicone
Clean gently: no scraping, scouring pads or harsh chemicals.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into whatever is behind or below. Sorting it early limits the damage.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
