Stewartfield: questions and answers

Can you work on a hospital site such as Hairmyres Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Will our hotel in Stewartfield need to close for the work?

In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Can washrooms stay open while you work?

Only the area we are working in is closed. Each room reopens after the sealant’s cure time and we start the next.

About our washroom sealing in Stewartfield

Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. We work on IPS panels and cubicles, kitchens and tea points and urinals and WCs, and what we’re called in for most is sealant laid over old silicone and now peeling and sealant lifting along a tray edge. Most enquiries from Stewartfield 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 Stewartfield, washrooms and kitchens are found in hotels, pubs, schools, care homes and halls. Mould grows into sealant in any wet room that doesn’t dry out, and the answer is removal and a fresh bead of anti-mould silicone.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

From enquiry to sign-off

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Where we can, we combine work around Stewartfield with other jobs nearby. Tell us how flexible your dates are.

  1. We inspect each washroom and record the joints to be resealed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

What we need from you

  • Point out any areas we must not close
  • Have the specification and drawings to hand
  • Let building users know which areas are affected

Advice

Maintenance after handover

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Mention any site permits or estates rules at quote stage
  • Brief cleaning staff to treat joints gently
  • Clear standing water from shower floors where possible
  • Keep washrooms out of use until we say the sealant has cured

Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.

Boards behind panels and vanity tops can swell when water gets past a failed joint. After that, those parts need replacing rather than resealing.

Toilets, showers and kitchens around Stewartfield

Stewartfield is on Scotland’s wetter western side. Damp air means a poorly ventilated washroom rarely dries out fully, which is when mould gets into the sealant. There are several hotels within about 2 miles of Stewartfield. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. The work can go floor by floor, agreed with housekeeping.

At a hospital like Hairmyres Hospital, which lies south-west of Stewartfield, patient and staff washrooms are best done in short phases agreed with the ward. Pupil toilets at schools like Duncanrig Secondary School take heavy daily use, and the holidays give the window to reseal. At a retail site such as Queensway Retail Park (1 mile south-west of Stewartfield), public and staff toilets see heavy use, so mouldy or split sealant is best replaced in phases.

Stewartfield is about 1 mile north of East Kilbride, in South Lanarkshire. Any commercial site in Stewartfield is covered. Stewartfield is one of 134 places we cover in South Lanarkshire for washrooms and wet areas. For work in that direction, see our Glasgow page.

How the quote is worked out

A fixed quote reflects the actual work. It allows for:

  • Induction, permit and paperwork requirements
  • Specialist products, such as fire-rated or hygienic sealants
  • The total length or number of joints
  • Any access equipment needed

Pricing washrooms and wet areas depends on how many there are, their condition and the access. Ask us for a fixed quote.

What we need to price the job

To price the job accurately, we need to understand the site. Useful things to include:

  • How the joints are reached, and at what height
  • Rough lengths or quantities, or drawings if you have them
  • A wide shot and a close-up of the area
  • Your programme or deadline

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

When to bring in a specialist

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.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What we can’t put right

Honesty saves time and money. New sealant won’t cure:

  • Failed tanking beneath a wet-room floor or behind tiles
  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Leaking pipes, traps, wastes or cisterns, which need a plumber

If you are not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer before you book.

What we seal

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

Surface by surface

Basins and vanity tops

A failed joint along a vanity unit lets water into the carcass. Resealing early protects the unit.

IPS and cubicle panels

Cubicle and IPS panels move when leaned on or knocked so the bead needs to cope with it. Loose panels are flagged before any sealant goes on.
