Commercial sealant in Downley
In a hotel, office or washroom, failed sealant is more than an eyesore. Cleaners struggle with it, water gets through it and people notice it. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. We work on student & care accommodation, retail & leisure sites and rental portfolios, and common reasons people get in touch are rental bathrooms that need resealing between tenants and large numbers of bathrooms needing the same work.
For holiday lets, converted business premises or a community building near Downley, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Common questions in Downley
Is Downley in your area for commercial sealant?
Yes. Our work covers London and the South East, and Downley is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Is Downley within the area you cover?
Yes. Downley is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you take on large, multi-room jobs?
Yes, we can. We work through big sites room by room or floor by floor, so only part of the building is affected at once.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
What should I tell you?
Let us know what needs doing and where. We will ask anything else we need to know.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Can you reseal between tenancies?
Yes. A planned programme across a portfolio keeps things simple, fitting around access to each property.
Where is Mr Mastic based?

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Give housekeeping the cure time for every room
- Keep strong chemicals and scourers off the joints
- Book larger programmes for quieter times of year
- Add sealant to your planned maintenance checks
Strong chemicals and scourers wear silicone out faster. A mild cleaner and a soft cloth is enough for the joints, with stronger products kept off the bead.
Water from a failed shower seal can travel: through floors, into ceilings and across into corridors. Early resealing keeps it from getting that far.
For landlords and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Why deal with it now?
Room by room, the work is quick: the job takes as long as the scope needs, from one welfare room to a full building. Each area is then left to cure for the time we give you, so planning the order matters more than the hours on site. In a small place like Downley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out 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.
The process
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the number of rooms in most cases. Somewhere as small as Downley, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- 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.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work

Workplaces and buildings in Downley
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For buildings such as St. James the Great, halls and community kitchens see heavy use, and their sealant shows it. Managing a site like The Downley School? Then sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.
