Surface by surface

Shower trays move under foot and are wet all day. Tray joints are where many washroom leaks start.
Changing rooms and gyms
Changing rooms can be phased so one stays open. Tell us your site hours and access windows and we’ll plan around them.
Washroom sealing in Carterton, done properly
Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, plus the kitchens and tea points that go with them. Product and method follow how hard each area is used and cleaned. If you have black mould inside silicone joints that cleaning can’t shift and washrooms that look worn because of the sealant, we can help, on showers, trays and wet room floors, kitchens and tea points and IPS panels and cubicles alike. Facilities teams, main contractors and managing agents in Carterton tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
For schools in a town such as Carterton, term dates decide when the toilets and changing rooms can be resealed, whereas care homes and offices normally need a few rooms at a time. Let us know your opening times and any access limits, and we will work to them.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

What else we do in Carterton
What happens if it’s left?
Running fresh silicone along a failed bead hides the problem briefly. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Cutting out completely and cleaning back takes a little longer and lasts. A failed joint is easier to put right before damp shows inside. Once water gets in, there’s drying out and making good as well.
A quote for washrooms and wet areas depends on how many there are, their condition and the access. Call for a quote.

Wet areas in Carterton’s workplaces
Central London is about 67 miles from Carterton. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open.
Pupil toilets at schools like Carterton Primary School take heavy daily use, and the holidays give the window to reseal. For an occupier at a site such as West Oxon. Industrial Park, under half a mile to the south-east of Carterton, the canteen and welfare facilities need cleanable joints as much as any office. For a hall at a building such as St John the Evangelist, resealing the kitchen and toilets can be fitted between bookings.

Should maintenance staff do it?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
A short, simple internal joint is often within reach of a maintenance team. 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.
Aftercare for building managers
For the best life from the joints:
- Share your site rules when you send details
- Don’t leave an open joint at a basin or tray
- Include joints in routine washroom inspections
- Avoid scourers and harsh descalers on silicone
If a joint we sealed fails within 12 months, tell us and we will look at it. After that, a routine look catches failing joints early.
Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.
