About our washroom sealing in Craigends

When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant, which is why it comes back however often it is treated. Only replacement gets rid of it for good. Most enquiries involve stained or open joints at kitchen sinks and worktops and split or peeling sealant at shower trays, across showers, trays and wet room floors, IPS panels and cubicles and urinals and WCs. Most enquiries from Craigends start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places such as Craigends, washrooms and kitchens are found in hotels, pubs, schools, care homes and halls. Black sealant normally can’t be cleaned, so it is removed and replaced with anti-mould sanitary silicone.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Commercial washrooms in Craigends

The west of Scotland, where Craigends is, gets more rain than the east. Washrooms with weak extraction stay damp in this climate, and mould finds the silicone first.

Units at estates like Mossedge Industrial Estate (to the south-east of Craigends) have welfare blocks whose showers and toilets see shift after shift. Church halls and community buildings, such as those at St Fillan's R.C. Church and School, have kitchens and toilets used by many groups, and their sanitary sealant works hard. At a school such as Gryffe High School, changing rooms and kitchens need cleanable joints as much as the toilets.

Craigends is about 2 miles north of Johnstone, in Renfrewshire. We send applicators to Craigends for washrooms and wet areas. We work across 23 places in Renfrewshire, large and small. We also cover Glasgow, around 10 miles from Craigends.

We also cover Crosslee (1 mile west), Houston (1 mile north-west), Brookfield (1 mile south), Linwood (1 mile south-east) and Bridge of Weir (2 miles west). Further afield, our area takes in Paisley (4 miles south-east), Renfrew (6 miles east), Erskine (4 miles north-east), Bishopton (3 miles north), Glenburn (5 miles south-east) and Charleston (5 miles south-east).

After the work

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Keep washrooms out of use until we say the sealant has cured
  • Mention any site permits or estates rules at quote stage
  • Include joints in routine washroom inspections
  • Keep a record of which washrooms need attention

Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.

Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. By then, other trades may be needed as well so failed joints are worth acting on quickly.

Questions about Craigends

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

Typically only some of them, for a short time. We work in phases so other facilities stay open. Each area is handed back once the sealant has cured enough to use.

Is Craigends too small for you to travel to?

No. Places such as Craigends are covered as much as the big towns. Our area covers all of Scotland, cities, towns and islands alike. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

When can showers be used after new sealant?

Each sealant has a cure time before it should get wet. We plan the phasing around that so there are always rooms open.

Do you do washroom sealing in healthcare settings?

Yes. Your infection-control rules, estates requirements and permits are followed. The work is phased around patients or residents.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Why act early in Craigends

Washrooms shape how visitors judge a building. Guests, clients, pupils and patients notice stained joints before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. For buildings near Craigends, dealing with all the failing joints at once saves return trips. Send photos and we’ll quote for everything together.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Why us?

  • Fixed quotes based on photos, drawings or a visit
  • RAL and finish matching where the product range allows
  • A Constructionline member, so easy to vet
  • Work to your specification and the manufacturer’s guidance

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • Loose panels, vanity units or tiles, which need fixing first
  • Failed tanking beneath a wet-room floor or behind tiles
  • Leaking pipes, traps, wastes or cisterns, which need a plumber

If you are not sure, just call 01277 525 020 or email the details over and we will give you a straight answer.

Surfaces we seal

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

How the job changes by surface

Urinals and WC pans

Pan and urinal joints face constant cleaning and splashing. Once they discolour or split, they hold odours and look unhygienic.

Showers and trays

A tray flexes every time it’s used and is constantly wet. Tray joints are where many washroom leaks start.

Should maintenance staff do it?

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Certain joints really need a specialist: 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.

Our process

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Tell us who will meet us and how to get in at your building near Craigends. That goes into the plan alongside the quote.

  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. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Rooms reopen after the cure time.

Getting the site ready

  • Share your working hours and any access restrictions
  • For older buildings, check the asbestos register before work
  • Make sure the joints can be reached
