Why deal with it now?
Sealant work is quick by the room: it takes a few hours per room, so whole buildings are phased. Each area is then left to cure for the time we give you, so the programme is planned around cure times. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and early is when they’re cheapest and quickest to sort.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.

Commercial sealant in Folkestone: local notes
If you run a hotel, guest house or holiday let in a coastal place like Folkestone, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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.
For landlords with property near Folkestone Central station, sealant work can be quoted for a single flat or a whole portfolio. If you look after a building such as Stella Maris Catholic Primary School, washroom and kitchen sealant can be programmed around term times or opening hours.
Folkestone is in Kent. Folkestone gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. Folkestone is one of 922 towns and villages in Kent where we work. For nearby work, see our Chelmsford page, about 54 miles away.
Our applicators cover all of CT20, CT19 and CT21 for commercial sealant and the streets around it. We cover properties on Christ Church Road, Middelburg Square and Station Road. With the A259 and A260 close by, Folkestone is easy for our applicators to reach. If you’re just outside Folkestone, we cover Cheriton (1 mile west), Sandgate (1 mile south-west), Hawkinge (2 miles north), Arpinge (2 miles north-west) and Seabrook (2 miles west). We also work in nearby towns such as Ashford (14 miles west), Canterbury (14 miles north), Dover (7 miles north-east), Deal (13 miles north-east), Hythe (4 miles west) and Tower Hamlets (7 miles north-east).

Local landmarks in Folkestone
Around Folkestone, our work takes us to homes and buildings near The Park Inn Hotel, Lower Leas Coastal Park and The Harvey Grammar School.

How it works
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 few hours per room, so whole buildings are phased. In Folkestone, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- The first visit is a look round the site to agree the scope.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Areas are protected and the failed sealant removed.
- Joints are dried, then resealed and tooled neatly.
- Housekeeping or site staff are told when each area can be used.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access
- For business premises, tell us about site rules or sign-in

Common questions in Folkestone
Is Folkestone in your area for commercial sealant?
Yes. Our work covers London and the South East, and Folkestone is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Do you work in hotels near Folkestone?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you work for landlords and letting agents?
Yes. Between tenancies is a good time to reseal bathrooms and kitchens and several properties can go on one quote.
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.
How long does the job take?
A typical job takes a few hours per area, with larger sites planned over several visits, including the preparation. Your quote will say how long we expect yours to take.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Different surfaces, different methods
Welfare facilities
Busy staff showers wear sealant out quickly. Anti-fungal sanitary silicone is used throughout, including accessible wet rooms.
Rental portfolios
Between tenancies is a good time to reseal, so the next tenant moves in to clean, sound joints.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Note the date each area was done
- Leave squeegees in busy showers
- Check the joints during routine room inspections
- Keep strong chemicals and scourers off the joints
We give a cure time for every area we finish, normally around 24 hours. Make sure housekeeping or cleaning staff know it so nobody showers or cleans the joint too early.
Mould in shared washrooms gets noticed and talked about. Left long enough, it spreads through the bead, so the fix is replacement.
When something else is needed
It helps to know what we cannot do:
- Extraction that is not working, which needs an electrician or ventilation contractor
- Certifying fire stopping or building compliance
- Cracked trays or baths rather than failed joints
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.
What we seal

Do you need commercial sealant in Folkestone?
In an accessible wet room, water spreads across the floor every use, so floor-to-wall joints take standing water. Any split there can let water through quickly.
The problems people usually mention when they call include:
- Large numbers of bathrooms needing the same work
- Failed floor-level joints in accessible wet rooms
- Sealant failing again soon after quick repairs
- Water marks on ceilings under bathrooms
Community buildings like United Reformed Church are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it.
