How we handle commercial sealant in Finmere
Wet areas get anti-fungal sanitary silicone, and kitchens get a food-safe product where it’s needed. Products include Arbo and Everbuild sealants, applied by ARBOMaster approved applicators. If you’re dealing with worktop sealant that has shrunk and stained and water marks on ceilings under bathrooms, we can put it right, whatever the surface.
If you have holiday lets, a converted barn used for business or a community building near Finmere, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

Your questions about commercial sealant in Finmere
Is there a guarantee on commercial sealant in Finmere?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Will you come out to Finmere?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you take on a whole building?
Yes. Larger jobs are planned as a room-by-room or floor-by-floor programme, so only part of the building is affected at once.
Do you work for landlords and agents?
Yes. Tell us the addresses and the rooms, and we will give you a clear price.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you’ll get one quote.
What affects the quote in Finmere
Your quote is based on your job. We take into account:
- How much old sealant there is and how hard it is to remove
- Access and height
- Working hours on commercial sites
- Which sealant suits the joint
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
What to tell us for a quote
To help us quote quickly, let us know:
- Roughly how big the job is
- Any previous sealing or DIY work
- The address or postcode of the job
- Photos by email, if that’s easy
We don’t publish a price list, because every job is different. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or send us an email.

What the job involves on each surface
Hotel bathrooms
We work through hotel rooms in agreed batches, so most rooms stay available. Each room is handed back with its cure time for housekeeping.
Office washrooms & kitchens
Office washrooms and tea points are used all day, so the work can be arranged for quieter times. We reseal around basins, urinals, worktops and sinks.
What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a morning for a small washroom, and a planned programme for bigger sites. For a village or hamlet like Finmere, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- In each room, the old bead comes out and the joint is cleaned and treated.
- We reseal with the right product for each joint.
- Rooms are handed back in order, each with its cure time.
How to prepare
- Clear items away from the joints we’re working on
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints

Advice
Why act early in Finmere
First impressions are often made in the washroom. Mouldy silicone looks unhygienic, however hard housekeeping work, and scrubbing will not fix it. New sealant does. Where a wall is exposed, as many are in small places like Finmere, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Cracked trays or baths rather than failed joints
- Faulty shower valves and leaking traps
- Certifying fire stopping or building compliance

Commercial sealant in Finmere: local notes
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
Community buildings like Church of St Michael are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it. Schools such as Finmere Church of England Primary School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Check extract fans are actually running
- Keep a record of which rooms were resealed and when
- Put a squeegee in each shower
- Book larger programmes for quieter times of year
Include sealant in routine room inspections. Checking joints alongside other room checks catches failures before they leak.
Water from a failed shower seal can travel: into ceilings below, walls next door and service voids. Dealing with the joint early stops that spread.
