The process
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. The work normally takes a few hours per area, with larger sites planned over several visits. Somewhere as small as Northbourne, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start with a site walk to agree the rooms and the timing.
- Each area is protected and the old sealant cut out completely.
- We clean the joints, treat any mould and let them dry.
- New sealant suited to each area is applied and tooled.
- We check every room and give its cure time for housekeeping.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can

What commercial sealant looks like in Northbourne
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Community buildings like Church of St Augustine are part of the picture too: its kitchen and washroom sealant needs looking after like anywhere else. If you look after a building such as Northbourne Church of England Primary School, washroom and kitchen sealant can be programmed around term times or opening hours.

FAQs for Northbourne
Do you cover smaller places like Northbourne?
Yes. Northbourne is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Northbourne for commercial sealant?
Yes. We work across London and the South East, and Northbourne is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Northbourne, along with the rest of our area.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Will there be a smell?
Some sealants have a smell while they cure. Ventilation helps.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can you reseal hotel rooms while we stay open?
Normally, yes. The order and timing are agreed with your team, and you will know when each room can be used.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
How to look after the new joints
So the new joints stay in good condition:
- Note the date each area was done
- Pass on the cure time to whoever cleans the rooms
- Keep extractor fans working and serviced
- Book larger programmes for quieter times of year
Make it easy for staff to flag a failing joint. A small gap caught quickly is a short fix.
Watch for the warning signs: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. Any of these means the joints need attention.
What sealant work can’t fix
New sealant can’t fix everything, and we will tell you before any work starts. It will not solve:
- Water damage behind the tiles that needs a tiler or builder
- A broken extractor fan behind the mould problem
- Assessing what fire stopping a building needs
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.

Do you need commercial sealant in Northbourne?
Internal washrooms and en suites without a window rely entirely on extraction, so if the fan is weak, steam lingers and the sealant stays damp. That’s when black mould sets into the bead.
People usually contact us when they notice something like this:
- Split sealant around staff kitchen worktops and sinks
- Large numbers of bathrooms needing the same work
- Rental bathrooms that need resealing between tenants
- Tired sealant ahead of a health and safety audit
Rented homes near Walmer station change hands often, and we can quote for one property or a whole portfolio of rentals.

Why deal with it now?
Before an inspection, audit or busy season, sealant is easy to overlook. Booking it in good time leaves room for the cure time before the visit. Around Northbourne, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.
