About our washroom sealing in Jarvis Brook

Not every silicone belongs in a washroom. Sanitary grades carry anti-mould additives, 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 accessible toilets and changing rooms, showers, trays and wet room floors and urinals and WCs, and the failures we’re asked to look at most are users noticing mouldy joints and kitchen worktop joints that can’t be kept clean. A specialist sealant contractor works differently from a general builder: on jobs in Jarvis Brook, preparation and product choice get the time they need.

In and around smaller places like Jarvis Brook, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Work we carry out in East Sussex comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or send details through our quote form and we will arrange a return visit.

Honest limits

We check first that sealant really is the fix. It isn’t the answer for:

  • A room that stays damp because ventilation isn’t working
  • Failed tanking beneath a wet-room floor or behind tiles
  • Panel boards already damaged by water

If you’re not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

What we seal

  • Kitchens and tea points
  • Urinals and WCs
  • IPS panels and cubicles
  • Vanity units and basins
  • Showers, trays and wet room floors
  • Accessible toilets and changing rooms

General trades versus a specialist

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.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Leave signs up until the cure time is over
  • Inspect washroom sealant regularly
  • Act on the first split you see at a shower tray
  • Brief cleaning staff to treat joints gently

Each room goes back into use only when the sealant has cured enough. You’ll be told when showers and basins can be used again, and it helps if signs stay up until then.

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.

How the job changes by surface

Showers and trays

Shower trays move under foot and are wet all day. Tray joints are where many washroom leaks start.

Changing rooms and gyms

We phase work so not every changing area is closed at once. Tell us your site hours and access windows and we will plan around them.

What happens if it’s left?

Water gets behind panels and under floors through a failed joint. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours, and fixing that takes far more work than resealing. Around Jarvis Brook, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

Sanitary sealant for Jarvis Brook buildings

At about 33 miles from central London, Jarvis Brook is within reach of the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, and resealing in phases keeps facilities available.

Church halls and community buildings, such as those at St Michael & All Angels, have kitchens and toilets used by many groups, and their sanitary sealant works hard. For a site such as Crowborough War Memorial Hospital, which lies west of Jarvis Brook, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. On an industrial estate such as Lexden Lodge Industrial Estate, under half a mile south-east of Jarvis Brook, staff toilets, showers and canteens are where sanitary sealant takes the most wear.

Jarvis Brook is about 1 mile east of Crowborough, in East Sussex.

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Jarvis Brook are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. We strip out the old bead and clean off the residue left behind.
  4. Joints are cleaned, degreased and dried before sealing.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Rooms reopen after the product’s cure time, and we move to the next.

What we need from you

  • Move anything stored against the joints
  • Flag any permit to work we’ll need
  • Share your working hours and any access restrictions

Questions about Jarvis Brook

Will the toilets in our Jarvis Brook building be out of use?

Rarely all at once: work is phased so some facilities are always available. We’ll tell you the curing time for the product before we start.

Is Jarvis Brook too far out for you?

No. Places such as Jarvis Brook are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, let us know and we will send them with the quote.

How do I request a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or email drawings and photos. Include photos or drawings if you have them.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Do you guarantee washroom sealing?

A 12-month guarantee covers the work. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.
