Do you need commercial sealant in Parsons Green?
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.
Most people get in touch after spotting one of these:
- Failed joints in office kitchens and tea points
- Large numbers of bathrooms needing the same work
- Tired sealant in let properties
- Mouldy washroom sealant that staff and guests notice
For site and facilities teams at buildings such as Lady Margaret School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.
What to look for in a quote

How we handle commercial sealant in Parsons Green
In student and care accommodation, there are often many near-identical bathrooms. We agree a programme and work through them in order, working around residents and staff routines. If you have black, stained silicone in guest bathrooms and sealant failing again soon after quick repairs, 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 is washroom resealing or fire-rated sealant around service openings. Where a building in Parsons Green needs to stay open, work can be planned outside normal hours.
There’s a 12-month guarantee on every job.

What affects the cost of commercial sealant
The price is agreed before any work begins. It takes into account:
- The old material and how stubborn it is
- Whether the work is at height
- The size of the job
- The number of rooms or windows
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Asking for a quote
When you contact us, these details help:
- Any access issues, like height or stairs
- A few pictures by email, if you can
- The type of property
- The address or postcode of the job
For a quote, call 0345 464 0079 or email us with the location and a short description of the problem. You will have a clear quote before we start.
What we cannot put right
In fairness, there are a few things sealant will not fix:
- Water damage behind the tiles that needs a tiler or builder
- Poor ventilation that keeps bringing mould back
- Fire risk assessments or certification
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.

Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Why it’s worth doing now in Parsons Green
Sealant is easy to forget until an audit or inspection is due. Planning the work ahead means rooms are finished and cured in time. 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 Parsons Green, the repair is bigger than the sealant job would have been.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
