Commercial sealant in Herne, done properly
For a rental portfolio, resealing between tenants keeps bathrooms and kitchens presentable. We can quote for several properties at once to keep things simple. We work on student & care accommodation, office washrooms & kitchens and welfare facilities, and people most often call us about leaks from showers into rooms or ceilings below and too many rooms to reseal without closing the building.
If you run a pub, café, guest house or shop in or near Herne, the washrooms and kitchen need the same attention as a big site.
All our work comes with a 12-month guarantee, wherever you are in Kent.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Honest limits
We will always be straight with you, so here’s what sealant cannot fix:
- Failed tanking or loose tiles behind the sealant
- Leaking pipework, valves or wastes (a plumber’s job)
- Fire risk assessments or certification
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.

What commercial sealant looks like in Herne
For seaside hotels, guest houses and holiday lets around Herne, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
Schools such as Herne Church of England Infant School are buildings too, and washroom and kitchen sealant can be programmed around term times or opening hours. For landlords with property near Herne Bay station, several rental properties can be resealed on one programme.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Encourage users to squeegee shower walls
- Check the joints during routine room inspections
- Ask cleaners to go gently on the silicone
- Give housekeeping the cure time for every room
Ask staff to report splits or lifting sealant early. Catching one split early can save a leak later, and if anything looks wrong, just call 0345 464 0079 or drop us an email.
Water from a failed shower seal can travel: through floors, into ceilings and across into corridors. Early resealing keeps it from getting that far.
Your questions about commercial sealant in Herne
Is Herne within the area you cover?
Yes, Herne is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Herne Bay station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
Can you reseal every bathroom in a hotel?
Yes. With more than 20 years’ experience and over 2,847 projects behind us, we plan big jobs so the building keeps running.
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.
What information do you need?
Let us know what needs doing and where, with photos by email if possible. We will ask anything else we need to know.
Where is Mr Mastic based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Signs you need commercial sealant in Herne
Commercial bathrooms get far more use than domestic ones, and they’re cleaned with strong products every day. So the silicone ages faster than it would at home.
Any of these means the joints need attention:
- Rental bathrooms that need resealing between tenants
- Repeated reseals that do not last
- Washroom sealant that looks dirty however often it’s cleaned
- Tired sealant ahead of a health and safety audit
For buildings such as Church of St Martin, its kitchen and washroom sealant needs looking after like anywhere else.
What your quote should include
- Who does the work, and how experienced they are
- What product goes in the joint
- How hidden problems are handled
- What preparation is included
What happens on the day
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours per room, so whole buildings are phased, and the area is left clean. In a smaller place like Herne, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We agree a programme with you: which rooms, in what order, at what times.
- We go through your site’s paperwork needs, such as RAMS, 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
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in

Related advice
Leave it or put it right?
Sealant work is quick by the room: it takes anything from a few hours to several days, depending on the number of rooms. Each area is then left to cure for the time we give you, so the programme is planned around cure times. Around Herne, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
