What the job involves on each surface
Office washrooms & kitchens
Office washrooms and tea points are used all day, so we can work early or out of hours where that can be arranged. Basins, urinals, worktops and sinks are all resealed.
Retail & leisure sites
Gym and leisure changing rooms take heavy use and plenty of water, so anti-fungal sanitary silicone is the product we use.
How we handle commercial sealant in Burnt Oak
Mr Mastic brings more than 20 years’ experience to commercial sites, and we’re fully insured and ARBOMaster approved. Tell us what paperwork your site needs, such as RAMS or insurance details, and we’ll confirm what we can supply with the quote. Common call-outs are for leaking joints in shower rooms and changing areas and split sealant around staff kitchen worktops and sinks, across office washrooms & kitchens, student & care accommodation and hotel bathrooms.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Burnt Oak, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

Why it’s worth doing now in Burnt Oak
Patching the worst rooms as complaints come in is hard to manage. A planned programme works through every room, with less disruption and one clear quote. In a flat in Burnt Oak, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
The cost depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

What affects the cost of commercial sealant
You’ll get a clear quote before we start. It takes into account:
- Whether the work is at height
- Whether there’s mould to deal with
- How many areas need sealing
- How much there is to do
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

- Access, such as stairs, a lift or height
- The problem you’ve noticed
- The address or postcode of the job
- If someone has resealed it before

Advice
Common questions in Burnt Oak
Can parking be tricky for a visit in Burnt Oak?
Parking in Burnt Oak, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you work for landlords with property near Mill Hill Broadway station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
How do I get a quote for commercial sealant in Burnt Oak?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before any work starts.
Can I choose the sealant colour?
Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before work begins.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
When can guests or staff use the shower again?
Plan for around 24 hours, or the cure time we give for that area. A room-by-room programme keeps only a few rooms out at once.
Can you reseal every bathroom in a hotel?
Yes. Our team has more than 20 years’ experience, and large programmes are planned around how the building is used.
Do you need commercial sealant in Burnt Oak?
Commercial bathrooms get far more use than domestic ones, and they’re cleaned with strong products every day. So the silicone ages faster than it would at home.
People normally contact us after spotting one of these:
- Large numbers of bathrooms needing the same work
- Repeated reseals that do not last
- Mouldy washroom sealant that staff and guests notice
- Mouldy bathrooms flagged at a tenancy check
As a London address, Burnt Oak can be tricky for parking: let us know about parking bays, permits or a driveway.
What your quote should include
- The length of the guarantee
- What the cure time is
- What product goes in the joint
- What happens if the job turns out different
Should I try it myself first?
Not every job suits DIY: 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 do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
For landlords and businesses
We work for landlords and agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
