How we handle commercial sealant in Blackstone
In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. We use sealants from Arbo and Everbuild, chosen to suit each joint. We’re often asked to deal with leaks from showers into rooms or ceilings below and split sealant around staff kitchen worktops and sinks, on rental portfolios, office washrooms & kitchens and student & care accommodation.
If you have holiday lets, a converted barn used for business or a community building near Blackstone, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or drop us an email.

Landlords, agents and businesses in Blackstone
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
How we quote for commercial sealant
We quote each job individually. These are the things that affect it:
- Whether there’s mould to deal with
- Access and height
- When we can work, for business premises
- The number of rooms or windows
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- If someone has resealed it before
- How we’d reach the joints
- The type of property
- The rough size of the job
Want a quote for commercial sealant? Please ring 0345 464 0079 or email us and tell us about the job. You will know what we plan to do, and what it will cost, before any work begins.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Get split or lifting joints looked at early
- Use mild cleaners on sealant, not bleach or abrasives
- Check the joints during routine room inspections
- Log resealing so you know what’s due
Make it easy for staff to flag a failing joint. Catching one split early can save a leak later, and if anything looks wrong, just phone 0345 464 0079 or drop us an email.
Rooms out of use cost a hotel or landlord money. Catching faults early means they can be put right in a short window, before they become leaks that take the room out of use.
Signs you need commercial sealant in Blackstone
Staff kitchens and food areas see constant splashing and wiping, so sealant there wears and stains. The worktop and sink edges normally fail first.
Any of these means the joints need attention:
- Large numbers of bathrooms needing the same work
- Tired sealant ahead of a health and safety audit
- Failed joints in office kitchens and tea points
- Leaking joints in shower rooms and changing areas
If you let a flat or house near Hassocks station, we can quote for one property or a whole portfolio of rentals.
Questions to ask before booking
- What preparation is included
- Whether you can choose the colour
- Whether they seal over old material or remove it
- Whether the sealant suits the joint
Commercial sealant around Blackstone
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a church, hall or community building such as The Parish Church of St Bartholomew, its kitchen and washroom sealant needs looking after like anywhere else.

What we do, step by step

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.
- 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.
- We reseal with the right product for each joint.
- Each finished area is checked with you and given a cure time.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed

What else we do in Blackstone
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you are 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 does not work out, we can still put it right.
Common questions in Blackstone
Will you come out to Blackstone?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Hassocks station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
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.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
