Different surfaces, different methods
Welfare facilities
Before a health and safety visit or audit, tired sealant is easy to sort. Let us know when it needs to be done and we’ll plan the work and cure time around it.
Retail & leisure sites
Gym and leisure changing rooms take heavy use and plenty of water, so joints are sealed with anti-fungal sanitary silicone.
How we handle commercial sealant in Basted
Guest bathrooms are cleaned every day and used by different people every night, so sealant there has a hard life. Rooms are resealed in batches, keeping most rooms available, with a cure time for each room so housekeeping know when to release it. We work on office washrooms & kitchens, student & care accommodation and rental portfolios, and common reasons people get in touch are black, stained silicone in guest bathrooms and tired sealant ahead of a health and safety audit.
In a village or hamlet like Basted, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
A 12-month guarantee comes as standard.

How the visit works
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours per area, with larger sites planned over several visits. Somewhere like Basted needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We agree a programme with you: which rooms, in what order, at what times.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- In each room, the old bead comes out and the joint is cleaned and treated.
- We reseal with the right product for each joint.
- Rooms are handed back in order, each with its cure time.

What affects the cost of commercial sealant
Jobs vary more than people expect. The main factors:
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- How many areas need sealing
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.
What to tell us for a quote
When you contact us, it’s useful to know:
- A few pictures by email, if you can
- Whether it has been sealed before
- The rough size of the job
- Whether it’s a home or a business

Basted: your questions answered
Will you come out to Basted?

Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Where are you based?
Mr Mastic is based in Crawley. We cover Basted and the rest of Kent.
Do you guarantee commercial jobs?
Yes. Every job, domestic or commercial, carries our one-year guarantee.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can you reseal between tenancies?
Yes. A planned programme across a portfolio keeps things simple, fitting around access to each property.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Book larger programmes for quieter times of year
- Check extract fans are actually running
- Act on lifting sealant before it leaks
- Tell cleaning staff when each room can be used
Each room is handed back with its cure time, which is normally around 24 hours. Make sure housekeeping or cleaning staff know it so the new sealant isn’t wetted or scrubbed too soon.
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.
Common problems we fix in Basted
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.
These are the problems we are asked about most:
- Whole floors of tired en suites
- Tired sealant ahead of a health and safety audit
- Water marks on ceilings under bathrooms
- Mouldy washroom sealant that staff and guests notice
If you look after a building such as Borough Green Primary School, busy washrooms and kitchens can be resealed in phases so they stay open.

Commercial buildings in Basted
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For landlords with property near Borough Green & Wrotham station, several rental properties can be resealed on one programme. If you look after a church, hall or community building such as The Church of the Good Shepherd, halls and community kitchens see heavy use, and their sealant shows it.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
