Common questions from West Stoke clients

Is hospital work, at somewhere like Nuffield Health Chichester Hospital, something you do?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is a smaller place like West Stoke outside your area?

No. Places such as West Stoke are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

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.

Can you reseal washrooms in healthcare buildings?

Yes. We work to your estates and infection-control requirements and any site permits. The work is phased around patients or residents.

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.

Which silicone is right for commercial washrooms?

Each area gets the grade that suits it. Most washroom joints take sanitary silicone while kitchens may need a food-safe grade.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

When to call us in West Stoke

Sometimes the sealant fails because something behind it is moving or wet: a loose panel, a leaking waste or water coming through the wall. We check for that first and say if it needs a plumber or another trade.

Look out for the following:

  • Failed sealant in a tea point or staff kitchen
  • Split or peeling sealant at shower trays
  • Failed sealant behind washroom basins
  • Urinal joints that look unhygienic

Student showers at universities like University of Chichester (2.8 miles south-east of West Stoke) see more use than most, and their silicone shows it.

How to choose a sealant contractor

Commercial clients in West Stoke

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

When to bring in a specialist

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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Keeping the joints sound

Problems stay small when the joints are checked regularly. Specifically:

  • Clear standing water from shower floors where possible
  • Brief cleaning staff to treat joints gently
  • Keep extract fans working and vents clear
  • Inspect washroom sealant regularly

If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, a routine look catches failing joints early.

A few failed joints can be resealed with hardly any disruption. Left, it tends to become a building-wide job and more closures to manage.

Leave it or put it right?

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 which costs more to fix than a reseal. For buildings around smaller places like West Stoke, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
