Sealant work for offices, hotels, washrooms and commercial buildings for homeowners, landlords and businesses in Knox Bridge. Fully insured, ARBOMaster approved and guaranteed for a year.
- Joints that need doing before an inspection or audit
- Water marks on ceilings under bathrooms
- Repeated reseals that do not last
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Book larger programmes for quieter times of year
- Note the date each area was done
- Report broken fans quickly
- Do not leave a failed joint until the next refurbishment
Daily cleaning with harsh chemicals shortens the life of any sealant. Ask cleaners to use mild products and soft cloths on the sealant.
Planned resealing is easier to manage than emergency repairs. Rooms can be scheduled around occupancy and staff, rather than closed at short notice.

Work for landlords, hotels and businesses
Hotels need rooms back in use, 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. On commercial sites, working times can be discussed when we quote.
What we do, step by step
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a morning for a small washroom, and a planned programme for bigger sites. Somewhere like Knox Bridge needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Tell us the rooms, hours and site rules, and we will plan the programme.
- Tell us what paperwork your site needs, and we confirm what we can supply before work begins.
- In each room, the old bead comes out and the joint is cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Each finished area is checked with you and given a cure time.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises

Rental portfolios
Good sealant prevents leaks that cause bigger repairs, especially where you rarely see the bathroom yourself.
Student & care accommodation
Care homes need careful planning around residents, with each bathroom handed back with its cure time.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
How we quote for commercial sealant
For a quick quote, just ask. The main things that affect it are:
- Working hours on commercial sites
- The type of sealant required
- How many areas need sealing
- Mould in or behind the old joints
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
Before you ask for a quote, have a think about:
- Roughly how big the job is
- What’s wrong with the joints now
- Photos by email, if that’s easy
- How we’d reach the joints
If you are in Knox Bridge and need commercial sealant, phone 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you will get a clear quote before any work starts.
Why it’s worth doing now in Knox Bridge
Fixing rooms one complaint at a time is the slow way. A planned programme works through every room, keeping disruption down and costs clear. In a small place like Knox Bridge, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

Common questions in Knox Bridge
Do you cover Knox Bridge for commercial sealant?
Yes. Our work covers London and the South East, and Knox Bridge is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
I let a flat near Staplehurst station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Can you send RAMS and insurance details for our site?
Let us know which documents your site needs, for example RAMS or insurance details, and we will confirm what we can provide when we quote.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
