Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Washroom sealing in Janetstown

From one staff toilet in Janetstown to washrooms across a whole estate, the route is the same: send details, get a fixed quote, we seal, guaranteed. A few photos and a count of fittings are enough for a quick quote, or we can arrange a visit. We work on accessible toilets and changing rooms, urinals and WCs and kitchens and tea points, and the usual reasons a site gets in touch are panel joints letting water behind and discoloured joints around urinals and WC pans. Most enquiries from Janetstown 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.

In smaller Scottish places like Janetstown, commercial washrooms are typically in hotels, pubs, schools, care homes and community halls. Black sealant usually can’t be cleaned, so it is removed and replaced with anti-mould sanitary silicone.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Looking after the joints

After handover, these steps help:

  • Keep washrooms out of use until we say the sealant has cured
  • Clean sealant with gentle products and a soft cloth
  • Inspect washroom sealant regularly
  • Squeegee showers and trays after busy periods

Where possible, have shower floors and trays squeegeed after busy periods. Standing water on a joint all day shortens its life.

In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.

Toilets, showers and kitchens around Janetstown

Janetstown sits close to the coast, within about 3 miles, and seaside hospitality typically has a peak season that works washrooms hard. Showers and en suites in constant use are where silicone moulds and splits first, so resealing in the quieter months keeps rooms ready. Being in the east of Scotland, Janetstown gets less rain than the west coast. Even so, a washroom that doesn’t dry out between uses will see mould get into its sealant.

At a school such as Thurso High School, changing rooms and kitchens need cleanable joints as much as the toilets.

Janetstown is about 3 miles south-west of Thurso, in Highland. Anywhere in KW14, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 256 places across Highland fall within our area, including Janetstown.

Postcode districts covered here: KW14. Just outside Janetstown, we also work in Glengolly (1 mile east), Westfield (2 miles south-west), Thurso (3 miles north-east), Scrabster (3 miles north) and Forss (3 miles north-west). Where a site is remote or on an island, travel and materials need planning ahead, so include the location in your enquiry.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Swollen or delaminated boards behind panels or vanity tops
  • Hollow tiles or loose panels behind the joint
  • A dripping waste or valve behind a panel

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Surfaces we seal

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

On site: what to expect

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a morning or so for a small washroom, longer where showers and changing rooms are included, and our waste is bagged and taken away as we go. Jobs near Janetstown are often grouped with others in the same area, to make the most of each trip. Tell us how flexible your dates are.

  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

  • Move anything stored against the joints
  • Explain the parking and delivery arrangements
  • For older buildings, check the asbestos register before work

Why deal with it now?

Running fresh silicone along a failed bead hides the problem briefly. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Cutting out completely and cleaning back takes a little longer and lasts. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Janetstown before they leak.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Why us?

  • Standard and matched colours in many product ranges
  • Our applicators hold CSCS cards
  • Clear, fixed quotes
  • One phone line for London, the South East and Scotland

Work for main contractors and building owners

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Janetstown can sit alongside others in a wider programme.

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

Your questions answered

Will all the washrooms in our Janetstown building be closed at once?

Usually only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we’ll tell you how long for the product used.

Is a smaller place like Janetstown outside your area?

Not at all: smaller places are covered as well as towns. We work across every Scottish council area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Will cleaning remove black mould from sealant?

Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Can you handle several sites?

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

Is any job too small?

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

Common problems we fix in Janetstown

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.

It’s worth sending us details if you spot any of the following:

  • Split or peeling sealant at shower trays
  • Kitchen worktop joints that can’t be kept clean
  • Open joints at the base of cubicle panels
  • Gaps where vanity tops meet the wall

For a site such as Dunbar Hospital, 1.8 miles to the north-east of Janetstown, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

What your quote should include

  • Their approach to joint depth and backing
  • Which product they’ll use, and why it suits the joint
  • How they handle RAMS and site documents
  • What level of public liability insurance do they hold?
