About our commercial sealant in Seven Kings
In a hotel, office or washroom, failed sealant is more than an eyesore. It’s a cleaning problem, a leak risk and something guests and staff notice. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. Common call-outs are for failed floor-level joints in accessible wet rooms and whole floors of tired en suites, on retail & leisure sites, student & care accommodation and office washrooms & kitchens.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Seven Kings, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

Seven Kings questions
Is parking a problem for a job in Seven Kings?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do you work for hotels and guest houses in Seven Kings?
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.
Can you quote for more than one area?
Yes, we can. More than one area can be quoted together.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or email us.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Is out-of-hours working possible?
Often, yes. Let us know when the building is quietest, and we’ll plan the work around them.
When to call us in Seven Kings
Heavy use means more movement: people of all sizes, daily cleaning and constant loading. If a tray flexes, the sealant around it splits.
Most people get in touch after spotting one of these:
- Black, stained silicone in guest bathrooms
- Worktop sealant that has shrunk and stained
- Whole floors of tired en suites
- Repeated reseals that do not last
If you let a flat or house near Seven Kings station, we can quote for one property or a whole portfolio of rentals.

What the job involves on each surface
Retail & leisure sites
Changing areas and showers at leisure sites are wet all day, so anti-fungal sanitary silicone is the product we use.
Welfare facilities
Before a health and safety visit or audit, tired sealant is easy to sort. Tell us your deadline and we will plan the work and cure time around it.
What sealant work can’t fix
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Poor ventilation that keeps bringing mould back
- Cracked trays or baths rather than failed joints
- Water coming from plumbing rather than sealant
If in doubt, call 0345 464 0079 or email us and we will say what we think before booking.
Where we work in Seven Kings

Leave it or put it right?
First impressions are often made in the washroom. Black sealant makes a clean room look dirty, and cleaning rarely puts it right. New sealant does. In a flat in Seven Kings, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Workplaces and buildings in Seven Kings
London has hard water, so limescale builds up on sealant, grout and fittings. Seven Kings has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
Managing a site like Downshall Primary School? Then sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. Community buildings like St John the Evangelist are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.

The process
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours per room, so whole buildings are phased. For a job in Seven Kings, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First we visit and agree the scope, the sequence and the working hours.
- Every area is sheeted and the old silicone stripped out.
- Joints are cleaned, treated for mould and dried.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- We check every room and give its cure time for housekeeping.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky
