Remedial sealant in Langley
Movement and expansion joints fail when the sealant cannot stretch. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. If you’re dealing with decorators’ caulk around a bath or shower and gaps opening along the back of the worktop, we can help, whatever the surface.
Homes around Langley are mostly houses and cottages rather than flats. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
You’re covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or email us.

How the visit works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere as small as Langley, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- 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
- Mention any parking rules near the property
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts

Advice
Landlord and commercial work in Langley
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
How the job changes by surface
Windows & doors
Frames resealed over the top end up with hard, layered mastic. We remove it all and clean back to sound surfaces.
Leaking trays & enclosures
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. We check both before any new sealant goes on.

Questions from Langley
Do you cover smaller places like Langley?
Yes, Langley is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Stevenage station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Do you guarantee remedial jobs?
Yes. Every job comes with our 12-month guarantee.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Can failed expansion joints be resealed?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Someone sealed over the old bead. Can you fix it?
Yes. We remove every layer; over-sealing fails because silicone won’t bond to silicone.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Do you need remedial sealant in Langley?
A lot of failed joints have been sealed over rather than replaced. Silicone does not bond to silicone, so the new layer peels, and damp and mould settle between them.
Look out for any of the following:
- Floor or wall movement joints that have failed
- Black mould underneath the bead
- Sealant applied over old sealant that has lifted
- Gaps opening along the back of the worktop
If you look after a building such as The Thomas Alleyne School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
What your quote should include
- What happens if they find a problem under the old sealant
- Who turns up on the day
- How long the guarantee is
- Whether VAT is included
What affects the quote in Langley
There’s no set price list. What we look at:
- The product the joint needs
- How many areas need sealing
- Any mould that needs treating
- How easy the joints are to reach
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- A few pictures by email, if you can
To get a quote, call 0345 464 0079 or email us and tell us where the job is and what the problem looks like. You’ll have a clear quote before we start.
Why act early in Langley
Remedial work takes longer than a straight reseal, but not by much: it takes a few hours for a typical bath or shower, longer where several layers have been applied. It’s far less disruption than resealing the same joint again and again. Around Langley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.
Why us?
- Anti-fungal sanitary silicone in wet areas
- Tidy, careful work

Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before booking.
