Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Vanity carcasses that have swollen
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Leaks through tanking or membranes below the finishes
If you’re not sure, just give us a call on 01277 525 020 or email us and we will give you a straight answer.
Joints and surfaces we work on
- Vanity units and basins
- Kitchens and tea points
- Accessible toilets and changing rooms
- IPS panels and cubicles
- Showers, trays and wet room floors
- Urinals and WCs
Washroom sealing in Washington, done properly
You can’t shut every toilet in an office, school or hotel at once. Work is phased by room or by section, so there are always facilities in use. Give us your site hours and access windows and the phasing is planned around them. If you’re dealing with stained sealant around pans and urinals and failed joints along IPS and cubicle panels, we can put it right, on accessible toilets and changing rooms, IPS panels and cubicles and kitchens and tea points alike. Facilities teams, main contractors and managing agents in Washington tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Community buildings around smaller places like Washington have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Quoting for work in Washington
The price varies from site to site. It mainly depends on:
- Distance, for remote addresses
- Phasing around occupants
- The total length or number of joints
- How much existing material needs removing
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
What we need to price the job
To price the job accurately, we need to understand the site. Useful things to include:
- The asbestos register, for older buildings
- Clear photos of the problem areas
- Anything awkward about access or site hours
- Your programme or deadline
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
Our process
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. Rural sites near Washington may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- The phasing is agreed so there are always facilities open.
- The failed silicone is stripped and every face scraped clean of residue.
- We clean and dry every surface so the new sealant can grip.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- You get a reopening time for every room, with signage left up until then.
Getting the site ready
- Agree which areas must stay open
- Point out parking and an unloading spot
- Let us know about inductions and permits
Request a quote
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Maintenance after handover
Regular inspection catches problems early. In particular:
- Keep washrooms out of use until we say the sealant has cured
- Act on the first split you see at a shower tray
- Inspect washroom sealant regularly
- Clean sealant with gentle products and a soft cloth
We hand each area back once the silicone has had the cure time the product needs. We’ll tell you when the wet areas can be used, and it helps if signs stay up until then.
A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme and more closures to manage.
Washroom sealing around Washington: what changes locally
Central London is about 43 miles from Washington. Business park offices have washrooms in daily use by staff, which is why the work is phased.
Where you are responsible for a hall attached to a building such as The Parish Church of St Mary, its kitchen and toilets need sealant that stays cleanable. At a school such as St Mary's CofE Primary School, changing rooms and kitchens need cleanable joints as much as the toilets. Office toilets at parks like Rock Business Park (to the north-east of Washington) take steady weekday use, and mouldy silicone soon shows.
Washington is about 6 miles north of Worthing, in West Sussex. If you are looking for washroom sealing in Washington, we can help, as we do across West Sussex.

Healthcare and care settings
We phase washroom sealing so care areas are never left without facilities. Records you need can be confirmed with the quote.
Kitchens and tea points
Worktop, sink and splashback joints in tea points take water and food. Sealed joints leave no gaps for food and dirt.
Why deal with it now?
Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. Sound, smooth joints are much easier to keep clean. Halls, stores and units around places like Washington may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Pricing washrooms and wet areas depends on how many there are, their condition and the access. Ask us for a fixed quote.
