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 will confirm what we can supply with the quote.

Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Where a building in Plumstead needs to stay open, work can be planned outside normal hours.

Signs you need commercial sealant in Plumstead
Commercial bathrooms get far more use than domestic ones, and daily cleaning with strong chemicals wears sealant down. That’s why sealant fails sooner.
Signs it’s time to call us include:
- Split sealant where wet room floors meet walls
- Washroom sealant that looks dirty however often it’s cleaned
- Split sealant around staff kitchen worktops and sinks
- Whole floors of tired en suites
As a London address, Plumstead can be tricky for parking: let us know about parking bays, permits or a driveway.
Questions to ask before you book
- What the quote includes, VAT included or not
- Whether they seal over old material or remove it
- The length of the guarantee
- Who turns up on the day
The process
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes anything from a few hours to several days, depending on the number of rooms in most cases. In a London area like Plumstead, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- The first visit is a look round the site to agree the scope.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Each area is protected and stripped of old sealant.
- Joints are dried, then resealed and tooled neatly.
- Housekeeping or site staff are told when each area can be used.
Before we arrive
- Let us know about parking restrictions
- Clear the area around the work
- Mention any sign-in or site rules at work premises

Leave it or put it right?
First impressions are often made in the washroom. Mouldy silicone looks unhygienic, however hard housekeeping work, and scrubbing won’t fix it. Replacing it does. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Plumstead.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.
