When it isn’t the sealant

- Certifying fire stopping or building compliance
- Failed tanking or loose tiles behind the sealant

How we handle commercial sealant in Langley Green
In student and care accommodation, there are often many near-identical bathrooms. We agree a programme and work through them in order, working around residents and staff routines. If you’re dealing with shower leaks reaching the floor below and sealant failing again soon after quick repairs, we can put it right.
For a pub, café, guest house or shop in or near Langley Green, the washrooms and kitchen need the same attention as a big site.
Our work is backed for twelve months.

What else we do in Langley Green
When to call us in Langley Green
Heavy use means more movement: people of all sizes, daily cleaning and constant loading. A tray that isn’t fully supported soon tears its seal.
Any of these means the joints need attention:
- Washrooms that need sorting before an inspection
- Black, stained silicone in guest bathrooms
- Tired sealant in let properties
- Leaking joints in shower rooms and changing areas
If you let a flat or house near Crawley station, we can quote for one property or a whole portfolio of rentals.
What your quote should include
- Whether VAT is included
- How long to leave it before use
- Which sealant they’ll use, and why
- How the joint is cleaned and prepared
What happens if it’s left?
Before an inspection, audit or busy season, sealant is easy to overlook. Booking it in good time leaves room for the cure time before the visit. In an older home around Langley Green, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email.

Surface by surface
Office washrooms & kitchens
Long vanity tops have joints that hold water and grime. We renew it in one tidy, continuous bead.
Retail & leisure sites
Customer washrooms are part of the impression a business makes, and clean, neat sealant makes them look cared for.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Act on lifting sealant before it leaks
- Report broken fans quickly
- Include the silicone on your room checklists
- Use mild cleaners on sealant, not bleach or abrasives
Extract fans need to work. Where a room has no window, the fan is what dries it out, and that is what keeps mould away.
Signs to look for: mould, splits, peeling corners or water marks downstairs. Any of these means the joints need attention.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Commercial buildings in Langley Green
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings. Langley Green is part of Crawley, one of the post-war new towns. Crawley was planned with its own industrial and business areas, so there are offices, units and workplaces not far from home. Each has washrooms, kitchens and fire-rated joints to keep in order.
For site and facilities teams at buildings such as Langley Green Primary, washroom and kitchen sealant can be programmed around term times or opening hours. For buildings such as Voice of Deliverance Full Gospel Church of God, any kitchen and washrooms need the same sealant care as any other building.

What we do, step by step
On the day, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before we start. Most jobs take a few hours for a single washroom, longer for a whole building. Parking around Langley Green is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We agree a programme with you: which rooms, in what order, at what times.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- In each room, the old bead comes out and the joint is cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Each finished area is checked with you and given a cure time.
Preparing for the visit
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
