Commercial sealant in Fortune Green, done properly
Staff facilities can’t be out of action for long. Early starts and out-of-hours work can be arranged to keep disruption down. You’re told when each area can be used again. Typical jobs include mouldy washroom sealant that staff and guests notice and shower leaks reaching the floor below, on hotel bathrooms, office washrooms & kitchens 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. Where a building in Fortune Green needs to stay open, work can be planned outside normal hours.
Our work is backed for twelve months, in Fortune Green and everywhere else we cover.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep extractor fans working and serviced
- Keep strong chemicals and scourers off the joints
- Pass on the cure time to whoever cleans the rooms
- Book larger programmes for quieter times of year
Each room is handed back with its cure time, generally around 24 hours. Make sure housekeeping or cleaning staff know it so nobody showers or cleans the joint too early.
Black sealant in a staff washroom or guest bathroom draws complaints. Left long enough, it spreads through the bead, so the fix is replacement.
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How we quote for commercial sealant
We quote each job individually. This is what makes a difference:
- How many rooms, windows or areas are involved
- Any mould that needs treating
- Working hours on commercial sites
- The number and length of the joints
Every job is a little different, 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.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- Access, such as stairs, a lift or height
- The rough size of the job
- The type of property
- The address or postcode of the job
Every job is quoted individually, so the first step is telling us about yours. Just call 0345 464 0079 or email us with the details and send pictures if you have them.
How the visit works
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the number of rooms. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Fortune Green. 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.
- Room by room, we protect the area and remove all the old sealant.
- We clean the joints, treat any mould and let them dry.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- Each room is checked and handed back with its cure time.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts
