Washroom sealing for businesses in Newington

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

Keeping the joints sound

Once the work is signed off, these steps help:

  • Photograph and log failed joints across the estate
  • Report faulty extraction promptly
  • Report split joints at trays and basins early
  • Clean sealant with gentle products and a soft cloth

Add washroom sealant to routine inspections. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and log what you find.

Mouldy sealant only gets harder to ignore, and complaints follow. Replacing it early keeps the job to a reseal.

How we handle washroom sealing in Newington

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Our workmanship is guaranteed for 12 months. We work on vanity units and basins, accessible toilets and changing rooms and urinals and WCs, and what we’re called in for most is washrooms that look worn because of the sealant and split or peeling sealant at shower trays. A single leaking joint is often how a building in Newington first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

City hotels, restaurants and bars in Scotland need washrooms that look cared for and kitchens that clean easily. We use anti-mould silicone in washrooms and food-safe hygienic sealant at kitchen worktops.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Fittings that move too much to hold a bead
  • Vanity carcasses that have swollen
  • A dripping waste or valve behind a panel

If in doubt, phone 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

Where we work in Newington

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

Leave it or put it right?

When a washroom looks worn, a refit isn’t the only answer. If the finishes are in good order, replacing the sealant may do much of what’s needed while bigger works are planned. In a Scottish city, access often needs scaffold, permits or factor approval, so deal with all failing joints while access is up.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Why us?

  • Clear, fixed quotes
  • Commercial sealant work since 2005

Newington: questions and answers

Do you work in occupied care homes around Newington?

Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.

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

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

How much does the work cost?

That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.

What if there’s asbestos in the old mastic?

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

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. Step one needs little more than photos and a postcode.

Can you quote from photographs?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Do you work in Newington?

Yes. We take on work across Newington, and the same phone number covers every area.

Owners, agents and contractors

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Newington can form part of a wider programme across Edinburgh.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Sanitary sealant for Newington buildings

Newington is within about 3 miles of the coast, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Washrooms used guest after guest wear their sanitary silicone faster, and the quieter months are the natural time to reseal. The 2 miles around Newington include five care or nursing homes. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. Rooms are done a few at a time at times agreed with the home.

For a site such as Astley Ainslie Hospital, 1 mile south-west of Newington, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. Office toilets at parks like Blackford Business Park (0.8 miles south-west of Newington) take steady weekday use, and mouldy silicone soon shows. In a centre such as Cameron Toll Shopping Centre, 0.9 miles south-east of Newington, public washrooms are resealed a block of facilities at a time.

Newington is about 1 mile south-east of Edinburgh, in Edinburgh. Anywhere in EH9, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. 174 places across Edinburgh fall within our area, including Newington.

Streets here include Lauder Road, Cobden Road and Meadow Lane, and sites on any of them can send details for a fixed quote. We also cover St Leonard's (1 mile north-east), Burgh Muir (1 mile south-west), Sciennes (1 mile west), Mayfield (1 mile south-east) and The Grange (1 mile west) for washrooms and wet areas. Nearby towns on our patch include Leith (3 miles north), North Leith (3 miles north), Queensferry (9 miles west), Timber Bush (3 miles north), Southhouse (3 miles south) and Newhaven (3 miles north).

Diagnose, treat, sign off

Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. City jobs in Newington normally need parking and loading planned. Shared closes, stairs and the property factor may need to be part of the plan.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Joints are cleaned, degreased and dried before sealing.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Getting the site ready

  • Send your site hours and access windows
  • Move anything stored against the joints
  • Let building users know which areas are affected

Related advice

General trades versus a specialist

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
