Commercial Sealant in Harlington
Problem with your washrooms, bathrooms and kitchens in Harlington? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Washroom sealant that looks dirty however often it’s cleaned

How we handle commercial sealant in Harlington
Wet areas get anti-fungal sanitary silicone, and kitchens get a food-safe product where it’s needed. We use sealants from Arbo and Everbuild, applied by ARBOMaster approved applicators. If you are dealing with failed joints in office kitchens and tea points and tired sealant ahead of a health and safety audit, we can put it right, whatever the surface.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Harlington, we agree timings and access before anything starts.
All of our work is guaranteed for twelve months.

Leave it or put it right?
Room by room, the work is quick: the job takes as long as the scope needs, from one welfare room to a full building. Each area is then left to cure for the time we give you, so planning the order matters more than the hours on site. In a flat in Harlington, 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.
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 play a part.
Why choose Mr Mastic in Harlington
- Anti-fungal silicone where joints get wet
- An ARBOMaster approved applicator

- A sealant colour to suit the surroundings
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
How the job changes by surface
Office washrooms & kitchens
In staff kitchens, we degrease joints before resealing, using a food-safe sealant by sinks where it’s needed.
Student & care accommodation
Halls and care homes often have many near-identical bathrooms. A room-by-room programme keeps the job efficient.
Signs you need commercial sealant in Harlington
In an accessible wet room, water spreads across the floor every use, so the joints at floor level are under water often. Any split there can let water through quickly.
If you can see any of these, it’s time to have the joints looked at:
- Leaking joints in shower rooms and changing areas
- Shower leaks reaching the floor below
- Failed joints in office kitchens and tea points
- Sealant failing again soon after quick repairs
For site and facilities teams at buildings such as William Byrd Primary Academy, busy washrooms and kitchens can be resealed in phases so they stay open.

Yes, with our one-year guarantee. Mild cleaning and good ventilation help it last.
Can you reseal hotel rooms while we stay open?
Yes. Rooms are done a few at a time, so only a few are out of use at once. Housekeeping are told when each room can be let again.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.

What happens on the day
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to several days, depending on the number of rooms. In Harlington, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We start by looking at the rooms and agreeing what’s needed.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Areas are protected and the failed sealant removed.
- Joints are dried, then resealed and tooled neatly.
- We let your team know the cure time for every area.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive

What sealant work cannot fix
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Leaking pipework, valves or wastes (a plumber’s job)
- Tiles coming off the wall
- Poor ventilation that keeps bringing mould back
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.
