Washroom sealing in Farningham
Accessible WCs, showers and changing areas have their own pinch points: shower trays, wet-room floor edges, basins and floor-to-wall junctions. Gaps in those places let water get under the floor or behind panels, so we look at them closely. Site teams most often ask us about shower tray joints that have opened up and stained or open joints at kitchen sinks and worktops, on vanity units and basins, kitchens and tea points and accessible toilets and changing rooms. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Farningham, preparation and product choice get the time they need.
Halls and community buildings near places like Farningham 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.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Surface by surface
Healthcare and care settings
Assisted bathrooms and accessible toilets get heavy use, so their joints often need renewing sooner.
IPS and cubicle panels
Panel systems meet walls, floors and vanity tops at sealed joints. They stop water reaching the panel boards.
When something else is needed
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Water escaping beneath the floor rather than through a joint
- Loose panels, vanity units or tiles, which need fixing first
- Mould caused by poor ventilation, which will return until the extract is fixed

Washroom sealing around Farningham: what changes locally

Farningham is about 16 miles from central London. Washrooms in commuter-belt offices take constant weekday traffic, so we work a block of facilities at a time.

For an occupier at a site such as Southern Cross Industrial Estate, 1.7 miles to the north-west of Farningham, the canteen and welfare facilities need cleanable joints as much as any office.

Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. The usual problems come from 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 anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Common problems we fix in Farningham
Much of the failed sealant we remove was applied over old silicone or residue. Silicone won’t adhere to a silicone bead so it peels away quickly.
Most enquiries start with one or more of the following:
- Discoloured joints around urinals and WC pans
- Sealant lifting along a tray edge
- Gaps where vanity tops meet the wall
- Kitchen worktop joints that can’t be kept clean
Student showers at universities like University of Greenwich, 4.7 miles north-east of Farningham, see more use than most, and their silicone shows it.

Questions about Farningham
Does a hotel in Farningham need to shut while its sealant is renewed?
Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we will plan around them.
Is Farningham too far out for you?
Not at all. Farningham is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
How much does the work cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Can the sealant be colour-matched?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
