About our commercial sealant in Chells
Mr Mastic brings more than 20 years’ experience to commercial sites, and we’re fully insured and ARBOMaster approved. If your site needs RAMS or insurance details, tell us, and we’ll confirm what we can provide. We’re often asked to deal with black, stained silicone in guest bathrooms and joints that need doing before an inspection or audit, across welfare facilities, hotel bathrooms and student & care accommodation.
If you run a pub, café, guest house or shop in or near Chells, the washrooms and kitchen need the same attention as a big site, and fire-rated sealant around service openings should be restored after new pipes or cables go through.
A one-year guarantee comes as standard, so you’re covered after we have gone.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
How the job changes by surface
Office washrooms & kitchens
Long vanity tops have joints that hold water and grime. It’s cut out, cleaned and resealed in one neat line.
Student & care accommodation
Care homes need careful planning around residents, and staff are told when each bathroom can be used.
What we cannot put right
New sealant can’t fix everything, and we will tell you before we start. It will not solve:
- Extraction that is not working, which needs an electrician or ventilation contractor
- Leaking pipework, valves or wastes (a plumber’s job)
- Fire risk assessments or certification
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.

Your questions about commercial sealant in Chells
Can you do commercial sealant in Chells?
Yes, Chells is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
Is Chells within the area you cover?
Yes, Chells is covered. 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.
Can you take on a whole building?
Yes, we can. Larger jobs are planned as a room-by-room or floor-by-floor programme, keeping most of it in use.
Can I choose the sealant colour?
Most of the time, yes. We’ll explain which colours are available.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
How long will you be here?
Typically it takes as long as the scope needs, from one welfare room to a full building. Bigger jobs take longer.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Do you work for letting agents and landlords?
Yes. Tell us the addresses and the rooms, and we’ll give you a clear price.
How the visit works
The work is kept neat and contained to the area we’re working on. Expect the work to take a few hours for a single washroom, longer for a whole building, and we explain the cure time before we leave. For a job in Chells, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start with a site walk to agree the rooms and the timing.
- Every area is sheeted and the old silicone stripped out.
- Joints are cleaned, treated for mould and dried.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- We check every room and give its cure time for housekeeping.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property

Advice
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Keep extractor fans working and serviced
- Check the joints during routine room inspections
- Keep strong chemicals and scourers off the joints
- Note the date each area was done
A squeegee in each shower is a simple help: less water sits on the joints between uses.
It’s easier to plan a programme than to react to failures. Rooms can be scheduled around occupancy and staff, instead of rooms closing without warning.
Commercial buildings in Chells
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. Stevenage, which Chells is part of, is one of England’s post-war new towns. Like the other new towns, Stevenage was planned with its own areas for industry and business, so there are offices, units and workplaces not far from home. Their washrooms, kitchens and fire-rated joints need the same upkeep as anywhere.
If you look after a church, hall or community building such as St Hugh & St John, any kitchen and washrooms need the same sealant care as any other building. Managing a site like The Nobel School? Then sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. For landlords with property near Stevenage station, sealant work can be quoted for a single flat or a whole portfolio.
