What we’re called out for in Kensal Green
Plenty of commercial bathrooms have no window at all, so if the fan is weak, steam lingers and the sealant stays damp. Mould then takes hold in the silicone.
The most common problems we see are:
- Silicone laid over old silicone by a previous contractor
- Large numbers of bathrooms needing the same work
- Failed joints in office kitchens and tea points
- Washrooms that need sorting before an inspection
For site and facilities teams at buildings such as Princess Frederica CofE Primary School, washroom and kitchen sealant can be programmed around term times or opening hours.
Questions to ask before booking
- How much experience the applicator has
- How long to leave it before use
- Is VAT in the price?
- How the joint is cleaned and prepared
Commercial sealant in Kensal Green, done properly
Hotel bathrooms take hard daily use and constant cleaning, so sealant wears out faster than it would at home. We work through rooms in batches, so only a few are out of use at once. If you have tired sealant in let properties and repeated reseals that don’t last, we can put it right, whatever the surface.
In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Kensal Green, and room-by-room programmes can be planned where needed.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Why it’s worth doing now in Kensal Green
In a building with rooms above rooms, a failed shower seal can soon show on a ceiling below. Then two rooms are out of action, not one. A reseal now avoids that. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Kensal Green.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Pass on the cure time to whoever cleans the rooms
- Put a squeegee in each shower
- Keep strong chemicals and scourers off the joints
- Get split or lifting joints looked at early
Each room is handed back with its cure time, which is usually around 24 hours. Make sure housekeeping or cleaning staff know it so the new sealant is not wetted or scrubbed too soon.
Black sealant in a staff washroom or guest bathroom draws complaints. The longer it’s left, the deeper it grows into the silicone, and only replacement fixes it.
How the visit works
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes anything from a few hours to several days, depending on the number of rooms in most cases. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Kensal Green. A visitor permit or a nearby bay makes the visit run more smoothly.
- 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.
- Each room is checked and handed back with its cure time.
Before we arrive
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in
- Tell us about any previous sealing or DIY attempts

Advice
How we quote for commercial sealant
We do not publish a price list, because no two jobs are the same. What we look at:
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- How many areas need sealing
- Any working-time requirements on site
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
Helping us quote
You do not need to know the technical terms. Just tell us:
- How we’d reach the joints
- Whether it has been sealed before
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work and send you a clear quote.

Workplaces and buildings in Kensal Green
Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed. London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Community buildings like St Martin are part of the picture too: any kitchen and washrooms need the same sealant care as any other building. As a London address, Kensal Green can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Different surfaces, different methods
Retail & leisure sites
Gym and leisure changing rooms take heavy use and plenty of water, so joints are sealed with anti-fungal sanitary silicone.
Office washrooms & kitchens
Kitchen and tea point joints are degreased and resealed, with a food-safe product beside sinks where needed.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Common questions in Kensal Green

Yes. We work for landlords and agents as well as homeowners. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Do you work in hotels near Kensal Green?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
What does commercial sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
How long do rooms need to be out of use?
Follow the cure time we give you, which is usually around 24 hours. Planning the order of rooms keeps that downtime manageable.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Do you cover Kensal Green?
Yes. We cover Kensal Green and the rest of Greater London. For a quote, call 0345 464 0079 or email us.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
