Signs you need commercial sealant in Swanscombe
Larger buildings move, and lightweight partitions flex more than masonry. Joints between different materials take the strain and eventually tear.
These are the problems we’re asked about most:
- Washrooms that need sorting before an inspection
- Leaking joints in shower rooms and changing areas
- Whole floors of tired en suites
- Silicone laid over old silicone by a previous contractor
If you look after a church, hall or community building such as Church of St Mary, halls and community kitchens see heavy use, and their sealant shows it.
What to look for in a quote
- What the cure time is
- Are they insured?
- Whether you can choose the colour
- Is the old sealant removed completely?
Commercial sealant in Swanscombe, done properly
Commercial work is planned around the building, not the other way round. We can work room by room, floor by floor or in batches, and out-of-hours work or early starts can be arranged. Typical jobs include failed floor-level joints in accessible wet rooms and black, stained silicone in guest bathrooms, on retail & leisure sites, welfare facilities and rental portfolios.
If you run a pub, café, guest house or shop in or near Swanscombe, its washrooms and kitchen need the same sealant care as any big building, and fire-rated sealant around service openings should be restored after new pipes or cables go through.
Every job comes with a 12-month guarantee.

What affects the quote in Swanscombe
We do not publish a price list, because jobs vary so much. The quote depends on:
- The old material and how stubborn it is
- Access and height
- The product the joint needs
- Working hours on commercial sites
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

Questions from Swanscombe
Do you cover Swanscombe for commercial sealant?
Yes, Swanscombe is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Can you help a landlord with a rental near Greenhithe for Bluewater station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Where are you based?
We work from Crawley. We cover Swanscombe and the rest of Kent.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can the hotel stay open while you work?
Normally, yes. The order and timing are agreed with your team, and you will know when each room can be used.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.

How to prepare

What the job involves on each surface
Retail & leisure sites
Retail and leisure sites have washrooms, kitchens and changing areas with sealant to maintain. We can plan around opening hours.
Hotel bathrooms
Hotel showers and baths get used and cleaned every day, so we use anti-fungal sanitary silicone and finish joints smooth for easy cleaning.
How to look after the new joints
To keep the joints looking good and working properly:
- Plan resealing around quiet periods
- Report broken fans quickly
- Note the date each area was done
- Use mild cleaners on sealant, not bleach or abrasives
Squeegees in guest and staff showers help: walls and trays dry faster, and so does the sealant.
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.
What happens if it’s left?
A quick bead over the old sealant might get a room back in use today, but silicone doesn’t bond to silicone, so it lifts. One proper reseal beats several quick ones. In a smaller place like Swanscombe, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Why choose Mr Mastic in Swanscombe
- A choice of colours where the product allows
- Any old sealant cut out fully, not covered over
- Homes, businesses and hotels
- More than 20 years in sealant work
Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
