How we handle washroom sealing in Nursted

When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Only replacement gets rid of it for good. Site teams most often ask us about users noticing mouldy joints and shower tray joints that have opened up, on showers, trays and wet room floors, vanity units and basins and IPS panels and cubicles. Most enquiries from Nursted start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Halls and community buildings near places like Nursted are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Your questions answered

Must every washroom in our Nursted building shut while you work?

Normally only some of them, for a short time. We work in phases so other facilities stay open. We’ll tell you the curing time for the product before we start.

Is a hospital such as Petersfield Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Are you insured?

Yes. We are fully insured, including public liability cover.

Can washrooms stay open while you work?

Just the room being resealed is out of use. Rooms go back into use once the sealant has cured, then we move on.

What’s the quickest route to a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

Will you quote for a small job?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards.

Busy facilities in and around Nursted

Central London is about 50 miles from Nursted, in a commuter belt where offices and business parks are common. Washrooms in commuter-belt offices take constant weekday traffic, so we phase work to keep some facilities open.

On a healthcare site such as Petersfield Hospital, which lies north-west of Nursted, washroom work starts with the infection-control team’s sign-off. Pupil toilets at schools like The Petersfield School take heavy daily use, and the holidays give the window to reseal.

What we can’t put right

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Panel boards already damaged by water
  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Failed tanking beneath a wet-room floor or behind tiles

If in doubt, speak to us on 01277 525 020 or email us and we will say what we think.

Surfaces we seal

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

Common problems we fix in Nursted

Panels and vanity units move slightly in use, and shower trays shift under foot. A bead that can’t cope with the movement splits along one edge.

If one of these sounds familiar, it’s time for a closer look:

  • Gaps where vanity tops meet the wall
  • Sealant laid over old silicone and now peeling
  • Washrooms that look worn because of the sealant
  • Open joints at the base of cubicle panels

Welfare facilities in units on estates such as Upper Adhurst Industrial Park (to the north of Nursted) have showers, toilets and kitchens with sealant that works hard.

Before you book anyone

  • What site paperwork they can supply
  • Which product they’ll use, and why it suits the joint
  • What level of public liability insurance do they hold?
  • How joint depth will be controlled

Choosing a commercial sealant contractor

Work for main contractors and building owners

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Nursted can sit alongside others in a wider programme across Hampshire.

Surface by surface

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’ll plan around them.

Showers and trays

In staff, hotel and changing-room showers, the tray joint and wall corners take the hardest use. Every joint is stripped, degreased, dried and given a new bead.

Site staff or a sealant specialist?

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, which is what makes a joint last.

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

Diagnose, treat, sign off

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. If others near Nursted need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Getting the site ready

  • Share your working hours and any access restrictions
  • Confirm the product named in the specification
  • Explain the parking and delivery arrangements

Getting a fixed quote

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
