We fit the work around your building. We can work room by room, floor by floor or in batches, and early starts or out-of-hours working can be arranged where it helps. Typical jobs include rental bathrooms that need resealing between tenants and sealant failing again soon after quick repairs, across student & care accommodation, welfare facilities and office washrooms & kitchens.
For holiday lets, converted business premises or a community building near Winchfield, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

Landlords, agents and businesses in Winchfield
We work for letting agents and landlords as well as householders. Sealant work between tenants keeps a property looking cared for.
Housing providers, facilities teams and property managers book us too in Winchfield and across Hampshire. Several sites can be quoted together, and we’re fully insured for the work.
Common problems we fix in Winchfield
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.
People usually contact us after spotting one of these:
- Split sealant around staff kitchen worktops and sinks
- Washroom sealant that looks dirty however often it’s cleaned
- Leaking joints in shower rooms and changing areas
- Tired sealant in let properties
For buildings such as Church of St Mary the Virgin, any kitchen and washrooms need the same sealant care as any other building.

What happens on the day
On the day, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take a few hours per room, so whole buildings are phased. For a village or hamlet like Winchfield, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Tell us the rooms, hours and site rules, and we’ll plan the programme.
- Tell us what paperwork your site needs, and we confirm what we can supply before we start.
- Old sealant is cut out room by room and joints cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Rooms are handed back in order, each with its cure time.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
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.

Can the hotel stay open while you work?
Yes. The order and timing are agreed with your team, and each room is handed back with a cure time.
How long will you be here?
Typically it takes a few hours for a single washroom, longer for a whole building. Bigger jobs take longer.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can you send RAMS and insurance details for our site?
Tell us what your site asks contractors for. We’ll confirm what we can supply before work is booked.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Different surfaces, different methods
Hotel bathrooms
Early starts or out-of-hours work can be arranged around check-out and check-in, agreeing the order with housekeeping.
Rental portfolios
Good sealant prevents leaks that cause bigger repairs.
What happens if it’s left?
Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and cleaning rarely puts it right. New sealant does. Around Winchfield, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.
What you get with us
- 4.9 on Google from 180+ five-star reviews

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Encourage users to squeegee shower walls
- Include the silicone on your room checklists
- Keep a record of which rooms were resealed and when
- Ask cleaners to go gently on the silicone
Extract fans need to work. Where a room has no window, the fan is what dries it out, and that’s what keeps mould away.
It’s easier to plan a programme than to react to failures. We can fit the work around bookings, shifts and opening hours, rather than closed at short notice.
