- Failed floor-level joints in accessible wet rooms
- Sealant failing again soon after quick repairs
- Large numbers of bathrooms needing the same work
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Leave squeegees in busy showers
- Get split or lifting joints looked at early
- Include the silicone on your room checklists
- Ask cleaners to go gently on the silicone
A squeegee in each shower is a simple help: walls and trays dry faster, and so does the sealant.
Water from a failed shower seal can travel: into ceilings below, walls next door and service voids. Dealing with the joint early stops that spread.
Commercial sealant for homes and businesses in Kilburn
Staff facilities cannot be out of action for long. We can plan the work for early mornings or out of hours to keep disruption down. Each area is handed back with its cure time. If you have washrooms that need sorting before an inspection and leaks from showers into rooms or ceilings below, we can help.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. For managing agents and building owners in Kilburn, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Kilburn: your questions answered
Is parking an issue for commercial sealant in Kilburn?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Do you take on hotel work around Kilburn?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or email us.
Can you do several jobs on one visit?
Of course. Doing several areas at once is usually more efficient.
When can guests or staff use the shower again?
Generally after around 24 hours. Each room is handed back with the cure time for the product used.

What affects the cost of commercial sealant
Call for a quick quote. The main things that affect it are:
- How much there is to do
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
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.
What we need to know
What to tell us when you ask for a quote:
- If it’s domestic, commercial or a hotel
- Where the property is
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.
Why act early in Kilburn
Sealant work is quick by the room: it takes a morning for a small washroom, and a planned programme for bigger sites. After that, each area needs its cure time before use, so planning the order matters more than the hours on site. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Kilburn, the repair is bigger than the sealant job would have been.
Leaving a failed joint generally makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.

What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours per room, so whole buildings are phased. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Kilburn. It helps if you can point us to a visitor permit or a bay close to the door.
- We agree a programme with you: which rooms, in what order, at what times.
- Tell us what paperwork your site needs, and we confirm what we can supply before we start.
- 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.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises

Related advice
Do you need commercial sealant in Kilburn?
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.
Common reasons people contact us include:
- Rental bathrooms that need resealing between tenants
- Failed joints in office kitchens and tea points
- Joints that need doing before an inspection or audit
- Whole floors of tired en suites
If you let a flat or house near Queens Park (London) station, several rental properties can be resealed on one programme.
What to look for in a quote
- Who does the work, and how experienced they are

- Is the old sealant removed completely?
- How the surfaces are prepared before sealing
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Faulty shower valves and leaking traps
- Extraction that isn’t working, which needs an electrician or ventilation contractor
- Water damage behind the tiles that needs a tiler or builder
If in doubt, call 0345 464 0079 or email us and we will say what we think.
Surfaces we seal
- Student & care accommodation
- Rental portfolios
- Retail & leisure sites
- Welfare facilities
- Office washrooms & kitchens
- Hotel bathrooms
