Leave it or put it right?
Cleaning mouldy sealant only masks it, but the mould is rooted in the silicone and comes back. A full reseal deals with it and cleaners stop fighting a losing battle. In Prittlewell, as anywhere, the simplest time to fix a failed joint is before it leaks. Once water gets in, there’s drying out and making good as well.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

About our washroom sealing in Prittlewell
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. We work on urinals and WCs, vanity units and basins and showers, trays and wet room floors, and the failures we’re asked to look at most are gaps where vanity tops meet the wall and complaints from staff, guests or users about tired washrooms. A specialist sealant contractor works differently from a general builder: on jobs in Prittlewell, preparation and product choice get the time they need.
For hospitality businesses in towns like Prittlewell, sealed joints in kitchens and toilets help keep surfaces easy to clean. Cleanable surfaces are something environmental health officers look at, and sealed joints help.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Sanitary sealant for Prittlewell buildings
Prittlewell is within about 1 mile of the coast, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Bathrooms turned round daily in the busy months need sound, cleanable joints, and the quieter months are the natural time to reseal. Prittlewell lies roughly 35 miles out from central London, in a commuter belt where offices and business parks are common. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open.
At a hospital like Southend University Hospital, 0.8 miles north-west of Prittlewell, patient and staff washrooms are best done in short phases agreed with the ward. On an industrial estate such as Tickfield Industrial Estate, less than half a mile east of Prittlewell, staff toilets, showers and canteens are where sanitary sealant takes the most wear. For a campus such as University of Essex, which lies south-east of Prittlewell, showers in residences and washrooms in teaching blocks can be programmed around term dates.

When something else is needed
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Water escaping beneath the floor rather than through a joint
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Loose panels, vanity units or tiles, which need fixing first
Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Your questions answered
Do you take on work at healthcare sites like Southend University Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you work around term dates at a campus such as University of Essex?
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.
How soon can a washroom be used after resealing?
The silicone needs time to cure before water reaches it. Phasing is planned with the cure time in mind so facilities are never short.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Will all the toilets be closed at once?
Just the room being resealed is out of use. Rooms go back into use once the sealant has cured and we start the next.
Do you guarantee washroom sealing?
Our workmanship has a 12-month guarantee, and we carry public liability insurance.
Work for main contractors and building owners
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Looking after the joints
Regular inspection catches problems early. In particular:
- Share your site rules when you send details
- Inspect washroom sealant regularly
- Clean sealant with gentle products and a soft cloth
- Respect the cure time before reopening each room
Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.
Small numbers of failed joints are quick to phase in. Left, it tends to become a building-wide job and more closures to manage.

When to bring in a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Town-centre premises in Prittlewell may have limited parking, so tell us what’s nearby. Industrial and business units normally have yard or car park space.
- We survey each room, count the joints and note anything behind them that needs another trade.
- The phasing is agreed so there are always facilities open.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- 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.
What we need from you
