- Failed joints in office kitchens and tea points
- Sealant failing again soon after quick repairs
- Shower leaks reaching the floor below
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Use mild cleaners on sealant, not bleach or abrasives
- Log resealing so you know what’s due
- Leave squeegees in busy showers
- Keep extractor fans working and serviced
Strong chemicals and scourers wear silicone out faster. 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. Catching faults early means they can be put right in a short window, instead of turning into a leak that closes the room.
Commercial sealant for homes and businesses in Friern Barnet
In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. We use sealants from Arbo and Everbuild, chosen to suit each joint. We work on retail & leisure sites, hotel bathrooms and student & care accommodation, and common reasons people get in touch are water marks on ceilings under bathrooms and silicone laid over old silicone by a previous contractor.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Friern Barnet, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
There’s a 12-month guarantee on every job, large or small.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
What we can’t put right
It helps to know what we can’t do:
- Poor ventilation that keeps bringing mould back
- Water coming from plumbing rather than sealant
- Cracked trays or baths rather than failed joints
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

Commercial buildings in Friern Barnet
There are hotels and other places to stay in and around Friern Barnet. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. London’s water is hard, so limescale builds up on sealant, grout and fittings.
Friern Barnet is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you let a flat or house near New Southgate station, we can quote for one property or a whole portfolio of rentals. If you look after a building such as Holly Park Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

Why deal with it now?
Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and cleaning rarely puts it right. New sealant does. 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. Dealing with it early is far simpler for homes in Friern Barnet.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

The process
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours per room, so whole buildings are phased. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We start with a site walk to agree the rooms and the timing.
- 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.
- Rooms are checked and returned with a cure time so staff know when to use them.
How to prepare
- Clear the area around the work
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive
