Washroom sealing in Longstone

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Different surfaces, different methods

Changing rooms and gyms

Shower areas, wet floor edges and vanity areas all have sealant joints and we look at them as one job.

Basins and vanity tops

Stone and some composite tops need a neutral-cure sealant, so the product is chosen to suit.

Washroom sealing in Longstone, done properly

In a busy washroom, the sealant usually gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day and mould that roots into it can’t be cleaned away. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. We work on accessible toilets and changing rooms, showers, trays and wet room floors and kitchens and tea points, and the failures we’re asked to look at most are panel joints letting water behind and mould spotting along silicone joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Longstone it comes down to the same thing: the right product in a properly prepared joint.

City hotels, restaurants and bars in Scotland need washrooms that look cared for and kitchens that clean easily. Washrooms get anti-mould sanitary silicone and kitchens hygienic sealant, food-safe where needed.

Our workmanship is guaranteed for 12 months, in Longstone as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Your questions answered

Will you plan work around the academic year at somewhere like Edinburgh Napier University?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Can you work on a hospital site such as Spire Murrayfield Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is it OK to put new silicone on top of the old?

The failed bead is always removed. Fresh silicone can’t key to an old bead so a bead over the top fails quickly.

How do I request a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.

Do you do washroom sealing in healthcare settings?

We work in clinics, hospitals and care homes. Tell us what records you need and we’ll confirm with the quote.

Which silicone is right for commercial washrooms?

Each area gets the grade that suits it. Most washroom joints take sanitary silicone while kitchens may need a food-safe grade.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Do you need washroom sealing in Longstone?

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 peels away quickly.

Look out for the following:

  • Washrooms that look worn because of the sealant
  • A new bead over an old one coming away
  • Sealant stained black around basins and showers
  • Failed joints along IPS and cubicle panels

Units at estates like Hailes Park Industrial Estate (less than half a mile west of Longstone) have welfare blocks whose showers and toilets see shift after shift.

What to look for in a quote

  • What level of public liability insurance do they hold?
  • Whether their applicators hold CSCS cards
  • Their approach to joint depth and backing
  • How long is the guarantee, and what does it include?

Questions to ask before you appoint anyone

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What we can’t put right

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
  • Condensation from failed extract fans
  • Water escaping beneath the floor rather than through a joint

If in doubt, speak to us on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

Joints and surfaces we work on

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

What affects the price in Longstone

Quotes vary with the job. It mainly depends on:

  • Phasing around occupants
  • Access and working height
  • Induction, permit and paperwork requirements
  • How much there is to seal

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Sending details for a quote

A few photos plus some basic facts will normally do. It helps to include:

  • A wide shot and a close-up of the area
  • When you need the work done
  • Where the site is, with the postcode
  • The product your specification calls for

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or send details through our quote form.

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 usually 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. University, hospital and office estates in Scotland’s cities have their own permits, inductions and sign-in rules. Tell us the rules and we’ll work to them.

  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 give you a reopening time for every room.

Before we start on site

  • Tell us which areas need to stay in use
  • Tell us what induction or permit system the site runs
  • Share your working hours and any access restrictions

Washroom sealing in Longstone: the local picture

Being in the east of Scotland, Longstone gets less rain than the west coast. Mould in sanitary sealant comes down to ventilation and use more than the weather outside. Longstone has 10 care or nursing homes no more than 2 miles away. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Each room is kept out of use only as long as the sealant needs.

Pupil toilets at schools like Merchiston Castle School take heavy daily use, and the holidays give the window to reseal. Clinical washrooms at sites like Spire Murrayfield Hospital, 1.4 miles north of Longstone, are scheduled with the ward so the room is out of use for as little time as possible.
