About our washroom sealing in Craigmillar

From one staff toilet in Craigmillar to washrooms across a whole estate, we work the same way: details first, then a fixed quote, then the work, then the 12-month guarantee. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote and a site visit is an option. If you’re dealing with failed joints along IPS and cubicle panels and complaints from staff, guests or users about tired washrooms, we can put it right, on showers, trays and wet room floors, accessible toilets and changing rooms and vanity units and basins alike. A single leaking joint is often how a building in Craigmillar first comes to us: we look at the rest while we are there and tell you what we find.

Scottish city buildings, from student residences to hospitals and offices, are full of washrooms and wet areas. We reseal them in phases, agreed with the estates or facilities team.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

When to call us in Craigmillar

A lot of failed washroom sealant was laid over an old bead or a dirty surface. New silicone won’t grip the old, so it soon lets go.

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

  • Black mould inside silicone joints that cleaning can’t shift
  • Open joints at the base of cubicle panels
  • Washrooms that look worn because of the sealant
  • Split or peeling sealant at shower trays

On a healthcare site such as Royal Infirmary of Edinburgh (Little France), 0.7 miles to the south of Craigmillar, washroom work starts with the infection-control team’s sign-off.

What your quote should include

  • Their pre-qualification and accreditations
  • How joint depth will be controlled
  • Will failed sealant be removed rather than covered?
  • Can the work be phased to keep areas open?

How to choose a sealant contractor

Commercial washrooms in Craigmillar

With the shore within about 3 miles, Craigmillar counts as a coastal location, and seaside hospitality usually has a peak season that works washrooms hard. Washrooms used guest after guest wear their sanitary silicone faster, which is why off-season resealing makes sense. Being in the east of Scotland, Craigmillar gets less rain than the west coast. Inside, ventilation and use decide how fast washroom sealant moulds, whatever the weather.

Halls of residence and teaching buildings at universities such as University of Edinburgh - Little France Campus (to the south of Craigmillar) are easiest to reseal during vacations. In a centre such as Craigmillar Shopping Centre, less than half a mile east of Craigmillar, public washrooms are resealed a block of facilities at a time.

Craigmillar is about 2 miles east of Newington, in Edinburgh. Craigmillar sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Craigmillar is one of 174 places we cover in Edinburgh for washrooms and wet areas.

What we can’t put right

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Fittings that move too much to hold a bead
  • Failed tanking beneath a wet-room floor or behind tiles
  • Swollen or delaminated boards behind panels or vanity tops

If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we will give you a straight answer.

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

Surface by surface

Wet-room floors and floor-to-wall joints

Changing rooms and accessible showers often have wet floors so the edges are checked carefully.

Healthcare and care settings

Healthcare work is phased so wards, clinics or residents’ areas keep their facilities. Tell us what records you need and we’ll confirm with the quote.

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. City jobs in Craigmillar usually need parking and loading planned. Tenement closes, shared stairs and factor approvals may also be involved.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  3. Failed sealant and residue are stripped out.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

Before we start on site

  • Point out any areas we must not close
  • Let building users know which areas are affected
  • Move anything stored against the joints

Getting a fixed quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Maintenance after handover

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Make sure washroom ventilation is running
  • Don’t leave an open joint at a basin or tray
  • Inspect washroom sealant regularly
  • Leave signs up until the cure time is over

Where possible, have shower floors and trays squeegeed after busy periods. Joints that sit wet for hours fail sooner.

Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.

Common questions from Craigmillar clients

Can you work on a hospital site such as Royal Infirmary of Edinburgh (Little France)?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can work at a site such as University of Edinburgh - Little France Campus fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

What sealant do you use in washrooms?

Each area gets the grade that suits it. Washrooms and showers take anti-mould sanitary silicone while kitchens may need a food-safe grade.

How long does a typical visit take?

It depends on the scope, but the work normally takes between a morning and a week or so, set by the number of rooms and the phasing you need. For bigger or phased jobs, we’ll set out a timescale with the quote.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Do you phase washroom resealing?

We phase it so users always have somewhere to go. We work through the building a room or section at a time around your site hours and access windows.
