What the job involves on each surface
Welfare facilities
Before a health and safety visit or audit, tired sealant is easy to sort. Let us know when it needs to be done and we’ll plan the work and cure time around it.
Retail & leisure sites
Retail and leisure sites have washrooms, kitchens and changing areas with sealant to maintain. We can plan around opening hours.
Commercial sealant in Comp, done properly
Commercial work is planned around the building, not the other way round. Rooms can be done one at a time, floor by floor or in batches, and out-of-hours work or early starts can be arranged where it helps. We work on student & care accommodation, office washrooms & kitchens and hotel bathrooms, and people most often call us about joints that need doing before an inspection or audit and failed joints in office kitchens and tea points.
For holiday lets, converted business premises or a community building near Comp, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
There’s a 12-month guarantee on every job.

Your questions about commercial sealant in Comp
Is Comp in your area for commercial sealant?
Yes, Comp is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Can you help a landlord with a rental near Borough Green & Wrotham station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Can you reseal every bathroom in a hotel?
Yes. After a site walk, we agree the scope and sequence, and give you one clear quote.
Can you work outside opening hours?
That can be arranged for many jobs. We will confirm the working hours with your quote.
How long does the job take?
Most jobs take a few hours per area, with larger sites planned over several visits, including preparation and clearing up. Your quote will say how long we expect yours to take.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Leave it or put it right?
Fixing rooms one complaint at a time is the slow way. A planned programme works through every room, with less disruption and one clear quote. Around Comp, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

- What the problem is, such as mould, gaps, leaks or cracking
- A few photos by email, if you can

How the visit works
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a single washroom, longer for a whole building. In a small place like Comp, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we visit and agree the scope, the sequence and the working hours.
- Every area is sheeted and the old silicone stripped out.
- We clean the joints, treat any mould and let them dry.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- We check every room and give its cure time for housekeeping.
How to prepare
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can

- Failed tanking or loose tiles behind the sealant
- Assessing what fire stopping a building needs
- Damaged sanitaryware that needs replacing

Commercial sealant in Comp: local notes
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
Letting a property close to Borough Green & Wrotham station? Then we can quote for one property or a whole portfolio of rentals. Community buildings like Church of St Mary are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.

It’s worth asking for a quote if you see:
- Tired sealant ahead of a health and safety audit
- Worktop sealant that has shrunk and stained
- Too many rooms to reseal without closing the building
- Rental bathrooms that need resealing between tenants
For site and facilities teams at buildings such as Platt Church of England Voluntary Aided Primary School, busy washrooms and kitchens can be resealed in phases so they stay open.
