Catherington: questions and answers
Would you work within a site like Havant War Memorial Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Will you work in a care home in Catherington without moving residents out?
Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.
Do you use special sealant for toilets and showers?
An anti-mould sanitary silicone in the majority of cases. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Can you reseal washrooms in healthcare buildings?
We do. We work to your estates and infection-control requirements and any site permits. The work is phased around patients or residents.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Washroom sealing for commercial buildings in Catherington
Washroom joints need the right sealant, not whatever is to hand. Sanitary silicone contains additives that resist mould, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. The enquiries we see most involve mould spotting along silicone joints and sealant laid over old silicone and now peeling, on kitchens and tea points, IPS panels and cubicles and urinals and WCs. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Catherington is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Halls and community buildings near places like Catherington are used by different groups through the week, and their toilets and kitchens show it. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Surface by surface
Wet-room floors and floor-to-wall joints
Sealant at a wet-room floor edge is not a substitute for the waterproofing underneath, and we will say if the trouble looks to be beneath the floor.
Showers and trays
Shower trays move under foot and are wet all day. Tray perimeters are a frequent source of leaks.
When to call us in Catherington
Panels and vanity units move slightly in use, and shower trays shift under foot. If the joint wasn’t laid to take that movement, it tears or peels away.
Clients typically get in touch after noticing something like this:
- Mould spotting along silicone joints
- Washrooms that look worn because of the sealant
- Failed sealant behind washroom basins
- Panel joints letting water behind
Schools such as Catherington Church of England Infant School have toilets, changing rooms and kitchens that are best resealed in the holidays.
Questions to ask before you book
- How the existing material will be dealt with
- Whether their applicators hold CSCS cards
- Do they follow the manufacturer’s priming guidance?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes between a morning and a week or so, set by the number of rooms and the phasing you need. For a building around Catherington, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- We survey each room, count the joints and note anything behind them that needs another trade.
- A phasing plan keeps part of the building’s facilities in use at all times.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- Joints are cleaned, degreased and dried before sealing.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- Rooms reopen after the product’s cure time, and we move to the next.
What we need from you

Keeping the joints sound
After handover, a little attention goes a long way:
- Share your site rules when you send details
- Keep extract fans working and vents clear
- Respect the cure time before reopening each room
- Add sealant joints to planned maintenance checks
Where possible, have shower floors and trays squeegeed after busy periods. Joints that sit wet for hours fail sooner.
A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.
When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Loose panels, vanity units or tiles, which need fixing first
- Condensation from failed extract fans
- A dripping waste or valve behind a panel
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
