How we handle commercial sealant in Knave's Ash
Guest bathrooms are cleaned every day and used by different people every night, so sealant there has a hard life. We work through rooms in batches, so only a few are out of use at once, with a cure time for each room so housekeeping know when to release it. If you are dealing with split sealant where wet room floors meet walls and washroom sealant that looks dirty however often it’s cleaned, we can put it right, whatever the surface.
Work in a small place like Knave's Ash is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.
There’s a 12-month guarantee on every job, large or small.

Knave's Ash questions
Do you work for landlords with property near Herne Bay station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Will you come out to Knave's Ash?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or drop us an email.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Can you match the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in.
Is out-of-hours working possible?
Out-of-hours work and early starts can be arranged. Let us know your hours when you get in touch.
Landlord and commercial work in Knave's Ash
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for.
How the visit works
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes a morning for a small washroom, and a planned programme for bigger sites in most cases. Somewhere as small as Knave's Ash, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by looking at the rooms and agreeing what’s needed.
- We agree when we will work, with early or out-of-hours slots where they can be arranged.
- Each area is protected and stripped of old sealant.
- Once dry, every joint is resealed and tooled.
- We let your team know the cure time for every area.
Getting ready for the visit
- Tell us if parking is tricky
- Keep children and pets away from the work area
- Mention if the joints have been sealed before

Commercial sealant in Knave's Ash: local notes
If you run a hotel, guest house or holiday let in a coastal place like Knave's Ash, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Community buildings like Church of the Holy Cross are part of the picture too: its kitchen and washroom sealant needs looking after like anywhere else. Managing a site like Hoath Primary School? Then busy washrooms and kitchens can be resealed in phases so they stay open.

Around Knave's Ash

Why deal with it now?
Replacing a whole washroom takes time, money and several trades. If the fittings are in good order, new sealant is often all it needs. If something else is wrong, we’ll say so. Around Knave's Ash, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Keep strong chemicals and scourers off the joints
- Tell cleaning staff when each room can be used
- Put a squeegee in each shower
- Add sealant to your planned maintenance checks
Extract fans need to work. Where a room has no window, the fan is what dries it out, and that is what keeps mould away.
Signs to look for: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. Any of these means the joints need attention.
