About our commercial sealant in City of Westminster
Student halls, care homes and supported housing have many similar bathrooms. A room-by-room programme keeps the job organised, fitting around residents and staff. Common call-outs are for tired sealant in let properties and silicone laid over old silicone by a previous contractor, across office washrooms & kitchens, retail & leisure sites and student & care accommodation.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that’s washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in City of Westminster can’t close.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

What the job involves on each surface
Hotel bathrooms
We can plan around check-out and check-in times, with the order agreed with your team.
Retail & leisure sites
Customer toilets reflect on the business, and clean, neat sealant makes them look cared for.
How it works
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before work begins. Most jobs take a few hours per room, so whole buildings are phased. In City of Westminster, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We start by looking at the rooms and agreeing what’s needed.
- We agree when we’ll work, with early or out-of-hours slots where they can be arranged.
- Areas are protected and the failed sealant removed.
- Joints are dried, then resealed and tooled neatly.
- Housekeeping or site staff are told when each area can be used.
Before we arrive
- Mention any tricky access
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed

City of Westminster questions
Is parking a problem for a job in City of Westminster?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Do you work in hotels near City of Westminster?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What information do you need?
Tell us what needs doing and where. If we need more, we will ask.
Can you reseal bathrooms across several rental properties?
Yes. We reseal bathrooms and kitchens in rented homes, and we can quote for several addresses at once.
How long do rooms need to be out of use?
Normally after around 24 hours. We give a cure time for each area.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Water coming from plumbing rather than sealant
- Certifying fire stopping or building compliance
- Water damage behind the tiles that needs a tiler or builder
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Leave it or put it right?
Sealing over the old bead can seem the fastest option, but it will not bond, and it lifts again soon. One proper reseal beats several quick ones. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

When to call us in City of Westminster
Heavy use means more movement: different weights, constant use and daily cleaning. A tray that is not fully supported soon tears its seal.
Common reasons people contact us include:
- Washrooms that need sorting before an inspection
- Mouldy bathrooms flagged at a tenancy check
- Split sealant where wet room floors meet walls
- Leaks from showers into rooms or ceilings below
For landlords with property near Bond Street station, several rental properties can be resealed on one programme.
Before you book anyone

- Whether the sealant suits the joint
- What preparation is included
- How much experience the applicator has
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Keep a record of which rooms were resealed and when
- Don’t leave a failed joint until the next refurbishment
- Use mild cleaners on sealant, not bleach or abrasives
- Pass on the cure time to whoever cleans the rooms
A squeegee in each shower is a simple help: less water sits on the joints between uses.
In a commercial building, a leak can quickly spread beyond one room: into ceilings below, walls next door and service voids. Dealing with the joint early stops that spread.
