About our washroom sealing in Unthank

Accessible WCs, showers and changing areas have their own pinch points: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. An open joint there lets water track under flooring or behind wall panels, so we look at them closely. We work on urinals and WCs, vanity units and basins and IPS panels and cubicles, and what we are called in for most is black mould inside silicone joints that cleaning can’t shift and stained or open joints at kitchen sinks and worktops. For commercial sealant work in Unthank, you deal with one contact from quote to sign-off, whether it’s one building or several.

For washroom work around Unthank, we plan so every room on the list is done in one trip where possible. Photos of each washroom and a count of rooms help us quote and plan.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Questions about Unthank

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

Not all at once. We take one block of facilities at a time. We’ll tell you the curing time for the product before we start.

Is Unthank too small for you to travel to?

Not at all: smaller places are covered as well as towns. We work across every Scottish council area. We plan jobs in smaller places so return trips are kept to a minimum.

What’s the quickest route to a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

How long does a job like this take?

The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can you quote from photographs?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, with one point of contact.

Do you need washroom sealing in Unthank?

Occasionally a joint keeps failing because of a problem behind it: a loose panel, a leaking waste or water coming through the wall. We check for that first and tell you if another trade is needed.

Typical triggers for a call:

  • Complaints from staff, guests or users about tired washrooms
  • Discoloured joints around urinals and WC pans
  • Failed sealant behind washroom basins
  • Panel joints letting water behind

For a hall at a building such as West and St Columba's Parish Church, resealing the kitchen and toilets can be fitted between bookings.

Comparing quotes

  • Will RAMS and insurance details be available?
  • Is the sealant right for the movement and the substrate?
  • How the joint faces will be prepared and primed
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Our contractor checklist

Wet areas in Unthank’s workplaces

Unthank is on Scotland’s drier eastern side. Mould in sanitary sealant comes down to ventilation and use more than the weather outside.

Office toilets at parks like Brechin Business Park (to the south-west of Unthank) take steady weekday use, and mouldy silicone soon shows. Schools such as Brechin High School have toilets, changing rooms and kitchens that are best resealed in the holidays.

Unthank is about 7 miles west of Montrose, in Angus. Unthank sits inside our coverage and the rest of Angus, with the same fixed quotes and 12-month guarantee as everywhere else. Unthank is one of 65 places in Angus on our list. We also cover Dundee, some 22 miles away.

If you need washroom sealing in DD9, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. We cover commercial and managed buildings on Trinity Road, Eddie Avenue and Cookston Road. If your building is just outside Unthank, we cover Brechin (1 mile south), Little Brechin (2 miles north-west), Edzell (5 miles north), Edzell Woods (5 miles north) and Craigo (6 miles east). Further afield, our area takes in Arbroath (13 miles south), Forfar (11 miles south-west), Montrose (7 miles east), Kirriemuir (14 miles west), Letham (9 miles south-west) and Hillside (7 miles east).

Local landmarks in Unthank

We work on buildings around City Road Bar and Brechin Public Park, among other places. Well-known places in the area include Brechin Castle (0.9 miles south) and Brechin Town House Museum (0.7 miles south). Not far away are Caterthun and Duns Dish.

What happens if it’s left?

Running fresh silicone along a failed bead hides the problem briefly. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Full removal and proper cleaning is what makes the new joint last. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Unthank before they leak.

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.

Different surfaces, different methods

Wet-room floors and floor-to-wall joints

Wet-room floors and the joints where flooring turns up the wall need to stay sound. We reseal the floor-to-wall junctions and around drains where sealant is used.

Healthcare and care settings

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

Quoting for work in Unthank

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Specialist products, such as fire-rated or hygienic sealants
  • The total length or number of joints
  • Any access equipment needed
  • Travel to remote or island sites

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Sending details for a quote

A good diagnosis starts with the right details. Tell us:

  • When you need the work done
  • Asbestos survey details if the building is older
  • The product your specification calls for
  • The site address and postcode

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

On site: what to expect

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes a few hours for one toilet block, with bigger buildings phased across a number of visits, and our waste is bagged and taken away as we go. Where we can, we combine work around Unthank with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. The phasing is agreed so there are always facilities open.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Preparing the site

  • Share your working hours and any access restrictions
  • Explain the parking and delivery arrangements
  • Make sure the joints can be reached

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
