On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish.

Washroom sealing in Selsfield Common, done properly

When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant, which is why it comes back however often it is treated. Replacing the bead is the lasting treatment. The enquiries we see most involve mould spotting along silicone joints and discoloured joints around urinals and WC pans, on IPS panels and cubicles, urinals and WCs and vanity units and basins. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Selsfield Common is the same: the right product in a properly prepared joint.

In and around smaller places like Selsfield Common, 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.

Our workmanship is guaranteed for 12 months, in Selsfield Common as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Common questions from Selsfield Common clients

Is Selsfield Common too far out for you?

Not at all. Selsfield Common is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Can you work on a hospital site such as Queen Victoria Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Is there a guarantee on the work?

Our workmanship has a 12-month guarantee backed by public liability insurance.

Do you phase washroom resealing?

Only the area we are working in is closed. Each room reopens after the sealant’s cure time, then we move on.

How long before the toilets can reopen?

Each sealant has a cure time before it should get wet. Phasing is planned with the cure time in mind so facilities are never short.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How long do sealant joints last?

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

What the job involves on each surface

Healthcare and care settings

Accessible and assisted washrooms are used and cleaned intensively so their sealant tends to fail sooner.

Changing rooms and gyms

Gym and leisure changing rooms see showers running most of the day, so mould is a constant battle. We use anti-mould sanitary silicone throughout.

Site staff or a sealant specialist?

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

For managing agents and facilities managers

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

What affects the price in Selsfield Common

These are the things that shape the price:

  • Removal of failed or old sealant
  • Any access equipment needed
  • Working within restricted access windows
  • Distance, for remote addresses

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Details that help us quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Access details, including height
  • Approximate linear metres or a joint schedule
  • Any dates the work must fit around
  • Whether an asbestos survey exists

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or send details through our quote form if you’d rather talk the job through.

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Condensation from failed extract fans
  • Swollen or delaminated boards behind panels or vanity tops
  • Failed tanking beneath a wet-room floor or behind tiles

If you are not sure, just ring 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Joints and surfaces we work on

  • IPS panels and cubicles
