How we handle washroom sealing in Blacknest
In a commercial washroom, sealant is usually the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. Site teams most often ask us about washrooms that look worn because of the sealant and resealing that didn’t last because the old bead stayed, on vanity units and basins, showers, trays and wet room floors and accessible toilets and changing rooms. Facilities teams, main contractors and managing agents in Blacknest tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In and around smaller places like Blacknest, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Maintenance after handover
A few simple habits keep the new joints working:
- Add sealant joints to planned maintenance checks
- Act on the first split you see at a shower tray
- Clear standing water from shower floors where possible
- Keep extract fans working and vents clear
If a joint we sealed fails within 12 months, tell us and we will look at it. After that, a routine look catches failing joints early.
A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.
What happens if it’s left?
Washrooms shape how visitors judge a building. Visitors notice black sealant before they notice much else. Resealing is a modest task with a very visible payoff. Around Blacknest, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Wet areas in Blacknest’s workplaces
Central London is about 40 miles from Blacknest, in a commuter belt where offices and business parks are common. Washrooms in commuter-belt offices take constant weekday traffic, and resealing in phases keeps facilities available. Two care or nursing homes sit less than 2 miles from Blacknest. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. We plan the work with the manager so residents are disturbed as little as possible.
For a site such as Chase Community Hospital, 4.7 miles south of Blacknest, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. Student showers at universities like University for the Creative Arts (to the north-east of Blacknest) see more use than most, and their silicone shows it. For an occupier at a site such as Blacknest Industrial Park, less than half a mile to the south-west of Blacknest, the canteen and welfare facilities need cleanable joints as much as any office.
Blacknest is about 4 miles south-west of Farnham, in Hampshire.

Common questions from Blacknest clients
Can you work around term dates at a campus such as University for the Creative Arts?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can work in a care setting near Blacknest go ahead while residents are there?
Yes, with the manager deciding the order and timing of rooms. We follow the home’s own procedures throughout.
Is it possible to just clean mouldy silicone?
Typically not. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacement is the lasting fix.
Which silicone is right for commercial washrooms?
Each area gets the grade that suits it. Washrooms and showers take anti-mould sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Can you quote from photos?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
Is there a guarantee on the work?
A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.
