About our commercial sealant in Berry's Green
In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. Products include Arbo and Everbuild sealants, chosen to suit each joint. If you have sealant failing again soon after quick repairs and washrooms that need sorting before an inspection, we can help, whatever the surface.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Where a building in Berry's Green needs to stay open, work can be planned outside normal hours.
Each job carries a 12-month guarantee, whatever its size.

Workplaces and buildings in Berry's Green
London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.
Community buildings like Church of St Peter and St Paul are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it. Schools such as Cudham Church of England Primary School are buildings too, and sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

The process
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes 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 Berry's Green. It helps if you can point us to a visitor permit or a bay close to the door.
- 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 any work starts.
- Old sealant is cut out room by room and joints cleaned and treated.
- We reseal with the right product for each joint.
- Each finished area is checked with you and given a cure time.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can

Do you need commercial sealant in Berry's Green?
Wet rooms and accessible showers are designed for the whole floor to get wet, so the joints at floor level are under water often. A failed joint there can soon let water into the floor or walls.
These are the problems we are asked about most:
- Tired sealant ahead of a health and safety audit
- Black, stained silicone in guest bathrooms
- Worktop sealant that has shrunk and stained
- Leaks from showers into rooms or ceilings below
Rented homes near Chelsfield station change hands often, and we can quote for one property or a whole portfolio of rentals.
Questions to ask before booking
- Are they insured?
- What preparation is included
- Whether all the old sealant comes out first
- Who does the work, and how experienced they are
Looking after it afterwards
After the cure time, these simple habits help:
- Schedule work around occupancy
- Check extract fans are actually running
- Include the silicone on your room checklists
- Log resealing so you know what’s due
Each room is handed back with its cure time, usually around 24 hours. Pass it on to housekeeping or cleaners so the new sealant isn’t wetted or scrubbed too soon.
It’s easier to plan a programme than to react to failures. Rooms can be scheduled around occupancy and staff, rather than closed at short notice.
Why act early in Berry's Green
Replacing a whole washroom takes time, money and several trades. When the fittings are sound, renewing the sealant brings it back with far less upheaval. We will tell you if we find anything that needs another trade. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Berry's Green.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Your questions about commercial sealant in Berry's Green
Can you do commercial sealant in Berry's Green?
Yes, Berry's Green is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.
Can you help a landlord with a rental near Chelsfield station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Can you do several jobs on one visit?
Yes. Just list everything you need and we’ll quote it together.
Can you supply method statements and risk assessments?
We are fully insured, and we will go through your site’s requirements with you. We will confirm what we can supply when we quote.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
