How we handle commercial sealant in Crews Hill
Guest bathrooms are cleaned every day and used by different people every night, so sealant wears out faster than it would at home. Rooms are resealed in batches, so only a few are out of use at once, with a cure time for each room so housekeeping know when to release it. We are often asked to deal with too many rooms to reseal without closing the building and repeated reseals that don’t last, across student & care accommodation, welfare facilities and retail & leisure sites.
In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Crews Hill.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What happens if it’s left?
Fixing rooms one complaint at a time is the slow way. A planned programme works through every room, with less disruption and one clear quote. In a flat in Crews Hill, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why choose Mr Mastic in Crews Hill
- A 12-month guarantee on all work
- Approved under the ARBOMaster scheme

- Anti-fungal silicone where joints get wet

How the job changes by surface
Rental portfolios
Between tenancies is a good time to reseal, ready for the next tenant.
Student & care accommodation
Empty rooms between terms or tenancies are easy to reseal, but occupied rooms can be planned in as well.
Workplaces and buildings in Crews Hill
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. London’s water is hard, which leaves limescale on sealant, grout and taps.

Crews Hill: your questions answered
Is parking a problem for a job in Crews Hill?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you work for landlords with property near Crews Hill station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
Can you match the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you supply method statements and risk assessments?
Tell us what paperwork your site needs, for example RAMS or insurance details, and we’ll confirm what we can supply with the quote.
What should I tell you?
A short description and the location. We’ll ask anything else we need to know.
DIY versus a professional finish
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. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Quotes for commercial sealant in Crews Hill
Every job gets its own quote. This is what makes a difference:
- The type of sealant required
- The number and length of the joints
- Any mould that needs treating
- Access and height
Doing several joints on one visit is generally more efficient than separate visits. We’ll give you a clear quote for the lot.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
For a quote, ring 0345 464 0079 or email us with the location and a short description of the problem. You will have a clear quote before we start.
Landlords, agents and businesses in Crews Hill
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
The process
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours per room, so whole buildings are phased. In Crews Hill, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- 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.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- Each room is checked and handed back with its cure time.
Getting ready for the visit
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
