How we handle commercial sealant in Angel
Guest bathrooms are cleaned every day and used by different people every night, 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, with a cure time for each room so housekeeping know when to release it. Typical jobs include whole floors of tired en suites and mouldy bathrooms flagged at a tenancy check, across retail & leisure sites, student & care accommodation and office washrooms & kitchens.
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 Angel, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
We stand behind the work with a 12-month guarantee.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Report broken fans quickly
- Include the silicone on your room checklists
- Don’t leave a failed joint until the next refurbishment
- Keep a record of which rooms were resealed and when
Daily cleaning with harsh chemicals shortens the life of any sealant. Ask cleaners to use mild products and soft cloths on the sealant, with stronger products kept off the bead.
A room that can’t be let or used is lost income. Small sealant faults caught early can be fixed between bookings or tenancies, instead of turning into a leak that closes the room.
Commercial sealant around Angel
Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed. Angel has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
Angel is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you look after a building such as St John Evangelist RC Primary School, washroom and kitchen sealant can be programmed around term times or opening hours.

When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- A shower tray, bath or basin that is cracked or broken
- Faulty shower valves and leaking traps
- Extraction that is not working, which needs an electrician or ventilation contractor

Why it’s worth doing now in Angel
First impressions are often made in the washroom. Mouldy silicone looks unhygienic, however hard housekeeping work, and cleaning rarely puts it right. Replacing it does. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

FAQs for Angel
Is parking an issue for commercial sealant in Angel?
Parking in Angel, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you work for landlords with property near London Kings Cross station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or email us with the details for a clear quote.
Does commercial work come with a guarantee?
Yes. We give a 12-month guarantee on every job and are fully insured.
What does commercial sealant cost?
Size, access and the old material all affect the cost. Ask us for a quote.
Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Do you offer different sealant colours?
Yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before any work starts.
When can guests or staff use the shower again?
Around 24 hours is typical for sanitary silicone. Housekeeping get the cure time for each room.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a morning for a small washroom, and a planned programme for bigger sites. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Angel. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start with a site walk to agree the rooms and the timing.
- Every area is sheeted and the old silicone stripped out.
- We clean the joints, treat any mould and let them dry.
- New sealant suited to each area is applied and tooled.
- Each room is checked and handed back with its cure time.
Before we arrive
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
