Washroom sealing in Danehill

In a commercial washroom, sealant is typically the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. We work on showers, trays and wet room floors, urinals and WCs and accessible toilets and changing rooms, and the failures we are asked to look at most are panel joints letting water behind and stained sealant around pans and urinals. Whoever orders the work in Danehill, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Community buildings around smaller places like Danehill have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Aftercare for building managers

Regular inspection catches problems early. Specifically:

  • Squeegee showers and trays after busy periods
  • Respect the cure time before reopening each room
  • Keep extract fans working and vents clear
  • Inspect washroom sealant regularly

Any failure in our workmanship within the 12-month guarantee is ours to put right. Beyond that, regular checks keep small problems small.

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.

Different surfaces, different methods

Showers and trays

Shower joints in hotels, gyms and workplaces work hard. Every joint is stripped, degreased, dried and given a new bead.

Wet-room floors and floor-to-wall joints

Wet-room floors and the joints where flooring turns up the wall need to stay sound. Floor perimeters and sealant joints near drains are resealed.

FAQs: Danehill

Is a smaller place like Danehill outside your area?

Not at all. Danehill is within our area. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you work on a hospital site such as Princess Royal Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Do you do washroom sealing in healthcare settings?

We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote before we start.

Can you quote from photos?

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

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

How soon can a washroom be used after resealing?

Cure times vary by product and temperature. Each room gets its own reopening time from us, and signs stay up until then.

Work for main contractors and building owners

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Danehill can form part of a wider programme.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Leave it or put it right?

Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. Older rural buildings around Danehill move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

Why clients in Danehill choose us

  • Work to your specification and the manufacturer’s guidance

Do you need washroom sealing in Danehill?

Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed, and shower trays shift under foot. A bead that can’t cope with the movement splits along one edge.

Site and facilities staff are often the first to spot these:

  • Mould spotting along silicone joints
  • A new bead over an old one coming away
  • Urinal joints that look unhygienic
  • Kitchen worktop joints that can’t be kept clean

Halls linked to places like The Parish Church of All Saints host groups all week, which is hard on kitchen and toilet sealant.

What to look for in a quote

  • Whether old or failed sealant will be cut out, not overlaid
  • Are they CHAS accredited or on Constructionline?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Is the sealant right for the movement and the substrate?

Office washrooms on sites such as Horsted Keynes Business Park (to the north-west of Danehill) are in use all working day, so resealing is phased to keep some open.
