What affects the cost of commercial sealant
Every job gets its own quote. These are the things that affect it:
- The type of sealant required
- Access and height
- The number and length of the joints
- The old material and how stubborn it is
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.
What to tell us for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- Whether it has been sealed before
- A few pictures by email, if you can
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
Every job is quoted individually. Simply ring 0345 464 0079 or send us an email and describe the job, and pictures are welcome.
Commercial sealant in East Finchley
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 rental portfolios, office washrooms & kitchens and welfare facilities, and the jobs we see most are black, stained silicone in guest bathrooms and whole floors of tired en suites.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. Timings and access are agreed with the building before work starts in East Finchley.
Our work is backed for twelve months, in East Finchley and everywhere else we cover.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Ask cleaners to go gently on the silicone
- Check the joints during routine room inspections
- Do not leave a failed joint until the next refurbishment
- Tell cleaning staff when each room can be used
Make it easy for staff to flag a failing joint. A small gap caught quickly is a short fix.
In a commercial building, a leak can quickly spread beyond one room: into ceilings below, walls next door and service voids. Early resealing keeps it from getting that far.

Is parking a problem for a job in East Finchley?
Parking in East Finchley, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you quote for more than one area?
Yes. Just list everything you need and we will quote it together.
Can you match the sealant colour?
Generally, yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover East Finchley and the rest of Greater London, along with the rest of our area.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Can the hotel stay open while you work?
Yes. The order and timing are agreed with your team, and each room is handed back with a cure time.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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. Everything old must be removed first.
Honest limits
We’d rather tell you now than do work that won’t last, so these are the limits:
- Tiles coming off the wall
- Poor ventilation that keeps bringing mould back
- Faulty shower valves and leaking traps
If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer before you book.
