What happens if it’s left?
First impressions are often made in the washroom. Mouldy silicone looks unhygienic, however hard housekeeping work, and cleaning rarely puts it right. New sealant does. Where a wall is exposed, as many are in small places like Nether Wallop, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

What else we do in Nether Wallop
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Care homes need careful planning around residents, with each bathroom handed back with its cure time.
When something else is needed
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

How the visit works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a single washroom, longer for a whole building. For a village or hamlet like Nether Wallop, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by looking at the rooms and agreeing what’s needed.
- We agree when we’ll work, with early or out-of-hours slots where they can be arranged.
- Each area is protected and stripped of old sealant.
- Once dry, every joint is resealed and tooled.
- Housekeeping or site staff are told when each area can be used.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed

Advice
Your questions about commercial sealant in Nether Wallop
I let a flat near Grateley station. Can you help?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Do you cover Nether Wallop for commercial sealant?
Yes, Nether Wallop is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Can you work around guests in a hotel?
Generally, yes. The order and timing are agreed with your team, and each room is handed back with a cure time.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Nether Wallop, along with the rest of our area.
How soon can a room be used after resealing?
Around 24 hours is typical for sanitary silicone. We tell your team the cure time for every area.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or send us an email.
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Pass on the cure time to whoever cleans the rooms
- Report broken fans quickly
- Act on lifting sealant before it leaks
- Add sealant to your planned maintenance checks
Each room is handed back with its cure time, which is generally around 24 hours. Make sure housekeeping or cleaning staff know it so nobody showers or cleans the joint too early.
Signs to look for: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. When you see them, it’s time to plan a reseal.
When to call us in Nether Wallop
In an accessible wet room, water spreads across the floor every use, so the joints at floor level are under water often. A failed joint there can soon let water into the floor or walls.
The problems people generally mention when they call include:
- Worktop sealant that has shrunk and stained
- Leaking joints in shower rooms and changing areas
- Tired sealant in let properties
- Too many rooms to reseal without closing the building
For site and facilities teams at buildings such as Wallop Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.
