Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Washroom sealing in Knightwood, done properly
From one staff toilet in Knightwood to washrooms across a whole estate, the route is the same: send details, get a fixed quote, we seal, guaranteed. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. Most enquiries involve black mould inside silicone joints that cleaning can’t shift and split or peeling sealant at shower trays, across vanity units and basins, urinals and WCs and accessible toilets and changing rooms. A single leaking joint is often how a building in Knightwood first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Pub and restaurant kitchens around smaller places like Knightwood work hard on their joints. Sealed joints at sinks, worktops and splashbacks help keep the kitchen cleanable, using a food-safe product near food preparation.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What the job involves on each surface
Changing rooms and gyms
Changing rooms in gyms and leisure centres stay wet and warm so sealant there works very hard. We use anti-mould sanitary silicone throughout.
IPS and cubicle panels
Panels flex slightly in use, so the sealant has to take that movement. Loose panels are flagged before any sealant goes on.
Diagnose, treat, sign off
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Work in places the size of Knightwood is planned as a single visit where we can. Clear photos and measurements help us bring the right products.
- Every room is surveyed and the failed joints listed.
- The fixed quote sets out the rooms, the products and the phasing.
- Old sealant is removed completely and the faces cleaned.
- Each joint is cleaned and left dry.
- New anti-mould sealant goes in and is tooled neat.
- Rooms reopen after the cure time.
Preparing the site
- Clear stock, furniture or equipment away from the joints
- Warn occupants and staff about the work
- Agree which areas must stay open

Related advice
Signs you need washroom sealing in Knightwood
Daily commercial cleaning wears sealant faster than people expect. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead so grime sticks to the damaged surface.
These are often picked up first by site or facilities staff:
- Stained or open joints at kitchen sinks and worktops
- Users noticing mouldy joints
- Resealing that didn’t last because the old bead stayed
- Urinal joints that look unhygienic
Staff changing rooms and patient toilets at places like Wessex Hospital (1.9 miles east of Knightwood) need cleanable, sound silicone.

FAQs: Knightwood
Must a hotel around Knightwood close while you work?
In the majority of cases no closure is needed: we work room by room or floor by floor. Tell us your quiet periods and access windows and we’ll plan around them.
Could you schedule work at a campus like University of Southampton for the vacation?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you guarantee washroom sealing?
A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.
Do you work in hospitals, clinics and care homes?
We do. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or send details through our quote form. Include photos or drawings if you have them.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
What affects the price in Knightwood
The price varies from site to site. It mainly depends on:
- Phasing around occupants
- Backing rod, priming and other preparation
- The total length or number of joints
- How accessible the joints are
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Details that help us quote
The more we know, the firmer the quote. When you get in touch, include:
- How the joints are reached, and at what height
- Whether the building will be occupied during the work
- Clear photos of the problem areas
- Asbestos survey details if the building is older

What else we do in Knightwood
What happens if it’s left?
Cleaning mouldy sealant only masks it but the growth is inside the bead and returns. Replacement deals with the cause in the joint and cleaners stop fighting a losing battle. In a smaller place such as Knightwood, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
