Commercial Sealant in Chiswick
Sealant work for offices, hotels, washrooms and commercial buildings for homes and businesses in Chiswick and across Greater London. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Failed floor-level joints in accessible wet rooms
- Worktop sealant that has shrunk and stained
- Rental bathrooms that need resealing between tenants
Aftercare tips
Good habits help new joints last longer. Our tips:
- Get split or lifting joints looked at early
- Leave squeegees in busy showers
- Report broken fans quickly
- Keep a record of which rooms were resealed and when
Strong chemicals and scourers wear silicone out faster. A mild cleaner and a soft cloth is enough for the joints.
Planned resealing is easier to manage than emergency repairs. Rooms can be scheduled around occupancy and staff, instead of rooms closing without warning.
Commercial sealant in Chiswick, done properly
Mouldy or split sealant in a commercial building causes more than a bad impression. Cleaners struggle with it, water gets through it and people notice it. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. If you have worktop sealant that has shrunk and stained and mouldy washroom sealant that staff and guests notice, we can put it right, whatever the surface.
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 Chiswick cannot close.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

How the visit works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes anything from a few hours to several days, depending on the number of rooms. In Chiswick, 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 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 work begins.
- Old sealant is cut out room by room and joints cleaned and treated.
- We reseal with the right product for each joint.
- Rooms are handed back in order, each with its cure time.
Before we arrive
- Clear the area around the work
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Do you need commercial sealant in Chiswick?
Wet rooms and accessible showers are designed for the whole floor to get wet, so the joints at floor level are under water often. Any split there can let water through quickly.
Any of these means the joints need attention:
- Washrooms that need sorting before an inspection
- Rental bathrooms that need resealing between tenants
- Shower leaks reaching the floor below
- Failed floor-level joints in accessible wet rooms

What commercial sealant looks like in Chiswick
London’s water is hard, which leaves limescale on sealant, grout and taps. Chiswick has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
Community buildings like St. Nicholas Church are part of the picture too: any kitchen and washrooms need the same sealant care as any other building. For site and facilities teams at buildings such as The William Hogarth Primary School, busy washrooms and kitchens can be resealed in phases so they stay open.
