Washroom sealing in Dumbiedykes

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

Washroom sealing in Dumbiedykes

Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we’ll plan around them. Most enquiries involve stained sealant around pans and urinals and mould spotting along silicone joints, across showers, trays and wet room floors, accessible toilets and changing rooms and IPS panels and cubicles. Searching for sealant specialists in Dumbiedykes? We’ve been sealing commercial buildings since 2005.

Shops and offices at the foot of tenement blocks in Scottish cities often have compact staff washrooms and tea points. Compact, poorly ventilated rooms are hard on sealant.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Questions we are asked in Dumbiedykes

Is a hospital such as Astley Ainslie Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Must a hotel around Dumbiedykes close while you work?

Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we’ll plan around them.

Is it possible to just clean mouldy silicone?

Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.

What do you charge?

We don’t publish prices, as every site differs. Send photos or drawings and we’ll price it at a fixed figure.

Will you quote for a small job?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Commercial clients in Dumbiedykes

We work for building owners and managing agents on everything from one building to a spread of sites around Dumbiedykes. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

On site: what to expect

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work typically takes half a day to a day per washroom, depending on the number of fittings. In a Scottish city, kerbside space and loading need planning, especially near the centre. Tenement closes, shared stairs and factor approvals may also be involved.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

Getting the site ready

  • Move anything stored against the joints
  • Confirm the product named in the specification
  • Agree which areas must stay open

General trades versus a specialist

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Keeping Dumbiedykes washrooms open while we work

Dumbiedykes sits close to the coast, within about 2 miles, and seaside hospitality typically has a peak season that works washrooms hard. Heavy seasonal use is hard on shower and basin sealant, so resealing in the quieter months keeps rooms ready. Being in the east of Scotland, Dumbiedykes gets less rain than the west coast. Mould in sanitary sealant comes down to ventilation and use more than the weather outside.

Student showers at universities like University of Edinburgh - Holyrood Campus, under half a mile north-west of Dumbiedykes, see more use than most, and their silicone shows it. Colleges such as Royal College of General Practitioners Edinburgh (to the north-west of Dumbiedykes) have toilets, changing rooms and catering kitchens that can be resealed around term dates.

Dumbiedykes is about 1 mile east of Edinburgh, in Edinburgh. We send applicators to Dumbiedykes for washrooms and wet areas, handled exactly as we handle every other area. Dumbiedykes is one of 174 places we cover in Edinburgh.

Business premises anywhere in EH8, EH1 and EH7 are within our area for washrooms and wet areas. Among the streets we cover are High Street, Calton Road and Hutton Road. Just outside Dumbiedykes, we also work in Holyrood (1 mile north-west), Canongate (1 mile north), Buccleuch (1 mile south-west), Old Town (1 mile west) and Greenside (1 mile north-west). Further afield, our area takes in Queensferry (9 miles west), Southhouse (3 miles south), Gilmerton (4 miles south-east), Muirhouse (3 miles north-west), Slateford (3 miles south-west) and Gracemount (3 miles south).

Local landmarks in Dumbiedykes

We work on buildings around St Cuthbert's Church, The World's End pub and Holyrood Park. You will also find Scottish Poetry Library (less than half a mile north), London Street Primary School (0.8 miles north-west) and St Trinnean's School (0.7 miles south-east). Dumbiedykes’s nearest station is Edinburgh Waverley station, about 0.5 miles west. A little further out are Deaconess Hospital (less than half a mile south-west) and Edinburgh Castle (0.9 miles west). The countryside around Dumbiedykes includes Dunsapie Loch and Salisbury Crags.

Looking after the joints

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Don’t leave trays and floors sitting wet
  • Share your site rules when you send details
  • Avoid scourers and harsh descalers on silicone
  • Make sure washroom ventilation is running

Ventilation is half the battle. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.

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.

What we are called out for in Dumbiedykes

Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They aren’t made for constant wetting and they discolour and fail early.

Common reasons buildings call us in:

  • Users noticing mouldy joints
  • Shower tray joints that have opened up
  • Failed joints along IPS and cubicle panels
  • Discoloured joints around urinals and WC pans

At a hospital like Astley Ainslie Hospital, which lies south-west of Dumbiedykes, patient and staff washrooms are best done in short phases agreed with the ward.

Before you book anyone

  • Will CSCS-carded applicators be on site?
  • Can the work be phased to keep areas open?
  • Will RAMS and insurance details be available?
  • How the existing material will be dealt with

Choosing a commercial sealant contractor

What the job involves on each surface

Showers and trays

Shower trays move under foot and are wet all day. Tray perimeters are a frequent source of leaks.

Changing rooms and gyms

Gym and leisure changing rooms see showers running most of the day, so mould is a constant battle. Anti-mould sanitary silicone is the standard choice.
