About our commercial sealant in Theydon Bois
In student and care accommodation, there are often many near-identical bathrooms. We agree a programme and work through them in order, working around residents and staff routines. We work on welfare facilities, office washrooms & kitchens and hotel bathrooms, and common reasons people get in touch are leaks from showers into rooms or ceilings below and black, stained silicone in guest bathrooms.
If you run a pub, café, guest house or shop in or near Theydon Bois, its washrooms and kitchen need the same sealant care as any big building.

Common problems we fix in Theydon Bois
In office kitchens and tea points, joints are wet and wiped all day, and grease and cleaning sprays break down sealant. Worktop and sink joints are often the first to go.
Most people get in touch when they notice something like this:
- Too many rooms to reseal without closing the building
- Black, stained silicone in guest bathrooms
- Split sealant where wet room floors meet walls
- Mouldy bathrooms flagged at a tenancy check
If you look after a church, hall or community building such as Parish Church of St Mary, its kitchen and washroom sealant needs looking after like anywhere else.

FAQs for Theydon Bois
Is Theydon Bois in your area for commercial sealant?
Yes, Theydon Bois is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Is Theydon Bois within the area you cover?
Yes, Theydon Bois is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can you reseal every bathroom in a hotel?
Yes, we can. We work through big sites room by room or floor by floor, keeping most of it in use.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
How long do rooms need to be out of use?
Around 24 hours is typical for sanitary silicone. We tell your team the cure time for every area.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
What we do, step by step
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the number of rooms. In a smaller place like Theydon Bois, 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 start by looking at the rooms and agreeing what’s needed.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Each area is protected and stripped of old sealant.
- Once dry, every joint is resealed and tooled.
- Housekeeping or site staff are told when each area can be used.
How to prepare
- Let us know about parking restrictions
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access

Advice
Leave it or put it right?
Sealant work is quick by the room: it takes a few hours for a single washroom, longer for a whole building. After that, each area needs its cure time before use, so planning the order matters more than the hours on site. Around Theydon Bois, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
