Washroom sealing for Longmoor sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Different surfaces, different methods
Showers and trays
If a tray moves too much or is cracked, it needs attention first and we flag that beforehand.
Wet-room floors and floor-to-wall joints
Floor edges in wet areas are where water most often escapes. We reseal the floor-to-wall junctions and around drains where sealant is used.
Washroom sealing in Longmoor, done properly
Not every silicone belongs in a washroom. Sanitary grades carry anti-mould additives, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. We work on urinals and WCs, showers, trays and wet room floors and vanity units and basins, and the usual reasons a site gets in touch are discoloured joints around urinals and WC pans and gaps where vanity tops meet the wall. Searching for sealant specialists in Longmoor? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Halls and community buildings near places like Longmoor are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Common questions from Longmoor clients
Do you take on work at healthcare sites like Chase Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Must every washroom in our Longmoor 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.
Can you handle several sites?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Will all the toilets be closed at once?
The work is phased so users always have somewhere to go. We work through the building a room or section at a time around your site hours and access windows.
What do you charge?
We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.
On site: what to expect
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Smaller jobs around Longmoor can be grouped with others nearby. A fixed quote is given before anything starts.
- First, the phasing is agreed so facilities stay open.
- Leaks, loose panels or damp are pointed out first.
- Old sealant is stripped and the faces prepared.
- We reseal with the grade suited to each area.
- We give you a reopening time for every room.
Getting the site ready
- Agree which areas must stay open
- Send asbestos survey details if the building is pre-2000

Wet areas in Longmoor’s workplaces
Central London is about 45 miles from Longmoor. Office washrooms on business parks see heavy weekday use, which is why the work is phased.
Office toilets at parks like Longmoor Enterprise Park, under half a mile west of Longmoor, take steady weekday use, and mouldy silicone soon shows. At a school such as Greatham Primary School, changing rooms and kitchens need cleanable joints as much as the toilets.

Signs you need washroom sealing in Longmoor
Mop buckets, trolleys and knocks from users damage joints near the floor, especially at floor edges and around urinals and WC pans.
If one of these sounds familiar, it’s time for a closer look:
- Sealant laid over old silicone and now peeling
- Shower tray joints that have opened up
- Mould spotting along silicone joints
- Urinal joints that look unhygienic
At a hospital like Chase Hospital, 2.3 miles to the north of Longmoor, patient and staff washrooms are best done in short phases agreed with the ward.

- Who will actually carry out the work
- The terms of the workmanship guarantee
- Health and safety accreditation such as CHAS
- Is the sealant right for the movement and the substrate?

We check first that sealant really is the fix. It won’t put right:
- Condensation from failed extract fans
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Leaks through tanking or membranes below the finishes
If in doubt, speak to us on 01277 525 020 or send details through our quote form and we will say what we think.

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
