About our washroom sealing in Down Street
In a busy washroom, the sealant usually 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. We strip it out and lay new anti-mould sanitary silicone. If you’re dealing with sealant laid over old silicone and now peeling and users noticing mouldy joints, we can put it right, whatever the surface. Whoever orders the work in Down Street, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Smaller places such as Down Street still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould usually can’t be cleaned, so it is cut out and replaced.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Questions we are asked in Down Street
Is Down Street too far out for you?
Not at all. Down Street is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Do you take on work at healthcare sites like Uckfield Community Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How long does a job like this take?
It depends on the scope, though a typical visit normally takes between a morning and a week or so, set by the number of rooms and the phasing you need. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
What site paperwork can you supply?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
Do you offer coloured sealant?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or send details through our quote form. Include photographs or drawings if you have them.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Avoid scourers and harsh descalers on silicone
- Report faulty extraction promptly
- Add sealant joints to planned maintenance checks
- Respect the cure time before reopening each room
Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.
Small numbers of failed joints are quick to phase in. Left, it tends to become a building-wide job with more phasing to plan.
Wet areas in Down Street’s workplaces
Down Street is about 35 miles from central London, within the office belt around the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, and resealing in phases keeps facilities available.
If you manage an office at a site such as Ashdown Business Park, which lies east of Down Street, the washrooms and tea points can be done a floor at a time. At a hotel such as Chequers Hotel, which lies east of Down Street, the quieter weeks are the time to reseal bathrooms. Church halls and community buildings, such as those at The Parish Church of St Andrew and St Mary, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

What else we do in Down Street
Surface by surface
Changing rooms and gyms
Gym and leisure changing rooms see showers running most of the day, so mould is a constant battle. Anti-mould sanitary silicone is the standard choice.
Urinals and WC pans
We reseal around urinals and pans with a sanitary grade once the whole of the old bead has gone.
When something else is needed
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Swollen or delaminated boards behind panels or vanity tops
- Leaks through tanking or membranes below the finishes
- A dripping waste or valve behind a panel
Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

Why it’s worth doing now in Down Street
Running fresh silicone along a failed bead hides the problem briefly. It doesn’t bond, so it peels and traps dirt behind it. Cutting out completely and cleaning back takes a little longer and lasts. Older rural buildings around Down Street move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
