Commercial sealant for homes and businesses in Copythorne
Mr Mastic brings more than 20 years’ experience to commercial sites, and we’re fully insured and ARBOMaster approved. If your site needs RAMS or insurance details, tell us, and we’ll confirm what we can provide. We are often asked to deal with washrooms that need sorting before an inspection and failed floor-level joints in accessible wet rooms, across rental portfolios, hotel bathrooms and student & care accommodation.
Somewhere as small as Copythorne, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
All our work is covered by a one-year guarantee, wherever you are in Hampshire.

What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours per room, so whole buildings are phased, depending on how much there is to do. Somewhere as small as Copythorne, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We walk the site with you and agree the rooms, the order and the hours.
- Room by room, we protect the area and remove all the old sealant.
- 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.
- Rooms are checked and returned with a cure time so staff know when to use them.
Preparing for the visit
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules

Related advice
Common problems we fix in Copythorne
Staff kitchens and food areas see constant splashing and wiping, and grease and cleaning sprays break down sealant. The worktop and sink edges usually fail first.
If you can see any of these, it’s time to have the joints looked at:
- Split sealant where wet room floors meet walls
- Sealant failing again soon after quick repairs
- Black, stained silicone in guest bathrooms
- Too many rooms to reseal without closing the building
Schools such as Copythorne CofE Infant School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open.
What to look for in a quote
- What happens if the job turns out different
- Who turns up on the day
- Whether all the old sealant comes out first
- Whether they’re fully insured
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Use mild cleaners on sealant, not bleach or abrasives
- Book larger programmes for quieter times of year
- Give housekeeping the cure time for every room
- Note the date each area was done
Squeegees in guest and staff showers help: less water sits on the joints between uses.
Mould in shared washrooms gets noticed and talked about. Left long enough, it spreads through the bead, so the fix is replacement.

Copythorne questions
Is Copythorne in your area for commercial sealant?
Yes, Copythorne is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.
Is Copythorne within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What should I tell you?
Let us know what needs doing and where, with pictures by email if possible. We will ask anything else we need to know.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can the hotel stay open while you work?
Yes. We work through rooms in batches, so only a few are out of use at once. Housekeeping are told when each room can be let again.
Can you reseal bathrooms across several rental properties?
Yes. For several properties, we can plan the work as one programme, fitting around access to each property.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
When it is not the sealant
We will always be straight with you, so here’s what new sealant will not do:
- Extraction that isn’t working, which needs an electrician or ventilation contractor
- Certifying fire stopping or building compliance
- Damaged sanitaryware that needs replacing
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.
