Advice
Washroom sealing in Netherfield
In a busy washroom, the sealant typically gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day and mould that roots into it can’t be cleaned away. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. We work on showers, trays and wet room floors, urinals and WCs and vanity units and basins, and the failures we are asked to look at most are urinal joints that look unhygienic and shower tray joints that have opened up. Searching for sealant specialists in Netherfield? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Questions we are asked in Netherfield
Must every washroom in our Netherfield building shut while you work?
Rarely all at once: work is phased so some facilities are always available. Each area is handed back once the sealant has cured enough to use.
Is Netherfield off your patch?
Not at all. Netherfield is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
What sealant do you use in washrooms?
Sanitary silicone with anti-mould additives in most cases. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Are you CHAS accredited?
Yes. We are CHAS accredited and a Constructionline member.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Signs you need washroom sealing in Netherfield
Much of the failed sealant we remove was applied over old silicone or residue. New silicone won’t grip the old, so it soon lets go.
Things that typically lead to an enquiry:
- Complaints from staff, guests or users about tired washrooms
- Panel joints letting water behind
- Mould spotting along silicone joints
- Open joints along basins and vanity units
Halls linked to places like Church of St John host groups all week, which is hard on kitchen and toilet sealant.
Questions to ask before you book
- What level of public liability insurance do they hold?
- Whether their applicators hold CSCS cards
- What the guarantee covers, and for how long
- How the joint faces will be prepared and primed
Surface by surface
Basins and vanity tops
Stone and some composite tops need a neutral-cure sealant and we choose a neutral-cure grade for them.
Showers and trays
A tray that rocks or has cracked won’t be fixed by sealant and we flag that beforehand.
Why it’s worth doing now in Netherfield
A tired washroom says a lot about how a building is run. Guests, clients, pupils and patients notice stained joints before they notice much else. Resealing is a modest task with a very visible payoff. Converted and older buildings near places like Netherfield tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.
Why us?
- Colours chosen to suit frames, cladding or finishes where possible
- A range of standard colours, depending on the product
- CHAS accredited contractor
- Colour agreed before work starts

Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Share your site rules when you send details
- Note failing joints building by building
- Make sure washroom ventilation is running
- Brief cleaning staff to treat joints gently
Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.
Boards behind panels and vanity tops can swell when water gets past a failed joint. After that, those parts need replacing rather than resealing.
