Kings Langley questions
Is Kings Langley within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Kings Langley station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
My shower still leaks after a reseal. Can you sort it?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
Can you remove sealant that’s been put over old sealant?
Yes. Both layers come out; over-sealing fails because silicone won’t bond to silicone.
What happens if the problem is the tray or the plumbing?
Then we explain what we have found. You may need a plumber or bathroom fitter.
Do you fix expansion and movement joints?
Yes. Where mortar or filler has been used instead of sealant, it’s removed where it can be, and reseal with a flexible product.
How we handle remedial sealant in Kings Langley
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We’re ARBOMaster approved and fully insured, and every remedial job comes with a 12-month guarantee. We work on leaking tray & enclosure joints, failed movement joints and mouldy bath & shower sealant, and common reasons people get in touch are leaks that keep coming back after resealing and gaps opening along the back of the worktop.
Homes around Kings Langley range from older cottages to more recent houses. Older homes can move a little with the seasons, which is hard on tired sealant and rigid grout.
Our work is backed for twelve months, in Kings Langley and everywhere else we cover.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Act on a lifting corner straight away
- Run the fan after every shower
- Always have old sealant cut out, not covered
- Use a soft cloth, not a scourer, on silicone
Go easy on the new sealant: a mild cleaner and a soft cloth, with no blades or scourers.
Don’t keep resealing the same joint. Have someone find out why, otherwise the next attempt will fail too.

Leave it or put it right?
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. In a smaller place like Kings Langley, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.

How we quote for remedial sealant
For a quick quote, just ask. What matters most is:
- Whether there’s mould to deal with
- The product the joint needs
- Whether old sealant or filler has to be cut out
- The amount of work
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
What we need to know
When you call or email, these details help:
- Where the property is
- Whether it has been sealed before
- What’s wrong with the joints now
- Any access issues, like height or stairs
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
What sealant work cannot fix
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Tiles that have come away from the wall
- Older mastics that may need an asbestos check before removal
- A cracked shower tray or bath (that needs repair or replacing)
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer before you book.

How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. A visit to Kings Langley 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.
- 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.
- 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.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules

Joints filled with mortar, grout or rigid filler can’t move. Where it can be raked out, we replace it with flexible sealant.
