Washroom sealing in South Wonston, done properly
Washroom joints need the right sealant, not whatever is to hand. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. If you have split or peeling sealant at shower trays and sealant laid over old silicone and now peeling, we can put it right, on showers, trays and wet room floors, urinals and WCs and IPS panels and cubicles alike. A specialist sealant contractor works differently from a general builder: on jobs in South Wonston, preparation and product choice get the time they need.
Rural businesses near smaller places such as South Wonston, from cafés to event venues, rely on washrooms and kitchens that stay clean. Tell us your opening times and quiet periods and we will plan around them.

Common problems we fix in South Wonston
Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They don’t stand up to constant water and they discolour and fail early.
Common reasons buildings call us in:
- Stained or open joints at kitchen sinks and worktops
- Washrooms that look worn because of the sealant
- Resealing that didn’t last because the old bead stayed
- Sealant stained black around basins and showers
On an industrial estate such as Beeches Industrial Park (2.3 miles south-west of South Wonston), staff toilets, showers and canteens are where sanitary sealant takes the most wear.
Questions to ask before you book
- Are they CHAS accredited or on Constructionline?
- Their public liability cover
- The terms of the workmanship guarantee
- Whether old or failed sealant will be cut out, not overlaid
What we can’t put right
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Condensation from failed extract fans
- Hollow tiles or loose panels behind the joint
- Water escaping beneath the floor rather than through a joint
If in doubt, call the office on 01277 525 020 or email us and we will say what we think.
What we seal
- Accessible toilets and changing rooms
- Urinals and WCs
- IPS panels and cubicles
- Vanity units and basins
- Showers, trays and wet room floors
- Kitchens and tea points
For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
After the work
Problems stay small when the joints are checked regularly. In particular:
- Respect the cure time before reopening each room
- Squeegee showers and trays after busy periods
- Mention any site permits or estates rules at quote stage
- Keep a record of which washrooms need attention
If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, regular checks keep small problems small.
Boards behind panels and vanity tops can swell when water gets past a failed joint. Once that happens, a reseal won’t fix them.
Surface by surface
Healthcare and care settings
Assisted bathrooms and accessible toilets get heavy use so their sealant tends to fail sooner.
Showers and trays
Shower joints in hotels, gyms and workplaces work hard. Each bead is stripped, the joint dried and new sealant laid.

Your questions answered
Can you work around term dates at a campus such as University of Winchester?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is South Wonston too far out for you?
Not at all. South Wonston is within our area. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
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.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

Yes. We are fully insured, including public liability cover.
