About our commercial sealant in Upper Hartfield
Office kitchens, staff washrooms and welfare facilities need to be usable every working day. Early starts and out-of-hours work can be arranged to keep disruption down. You are told when each area can be used again. If you have leaking joints in shower rooms and changing areas and failed joints in office kitchens and tea points, we can help.
In a village or hamlet like Upper Hartfield, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

Leave it or put it right?
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 the programme is planned around cure times. In a small place like Upper Hartfield, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

The process
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes a few hours for a single washroom, longer for a whole building. In a small place like Upper Hartfield, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- The first visit is a look round the site to agree the scope.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Areas are protected and the failed sealant removed.
- Once dry, every joint is resealed and tooled.
- Housekeeping or site staff are told when each area can be used.
How to prepare

Advice
Upper Hartfield: your questions answered
I let a flat near Ashurst Kent station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Will you come out to Upper Hartfield?
Yes. Upper Hartfield is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you take on large, multi-room jobs?
Yes, we can. Larger jobs are planned as a room-by-room or floor-by-floor programme, keeping most of it in use.
How long does the job take?
Most jobs take a few hours per room, so whole buildings are phased, including the preparation. Your quote will say how long we expect yours to take.
Do you provide RAMS?
Tell us what paperwork your site needs, for example RAMS or insurance details, and we’ll confirm what we can supply with the quote.
Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
What information do you need?
Tell us what needs doing and where, plus pictures if you have them. If we need more, we will ask.
Is out-of-hours working possible?
That can be arranged. The hours are agreed before work starts.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Log resealing so you know what’s due
- Keep extractor fans working and serviced
- Act on lifting sealant before it leaks
- Add sealant to your planned maintenance checks
Squeegees in guest and staff showers help: walls and trays dry faster, and so does the sealant.
Planned resealing is easier to manage than emergency repairs. We can fit the work around bookings, shifts and opening hours, instead of rooms closing without warning.
What we are called out for in Upper Hartfield
Wet rooms and accessible showers are designed for the whole floor to get wet, so floor-to-wall joints take standing water. A failed joint there can soon let water into the floor or walls.
These are the problems we’re asked about most:
- Mouldy bathrooms flagged at a tenancy check
- Washrooms that need sorting before an inspection
- Repeated reseals that do not last
- Whole floors of tired en suites
If you look after a church, hall or community building such as Holy Trinity Church, halls and community kitchens see heavy use, and their sealant shows it.
Before you book anyone
- The length of the guarantee
- Whether VAT is included
- How the surfaces are prepared before sealing
- Who does the work, and how experienced they are
Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
