There is public liability insurance behind every job. Our workmanship is guaranteed for 12 months.

What happens if it’s left?

Running fresh silicone along a failed bead hides the problem briefly. It doesn’t bond, so it peels and traps dirt behind it. Cutting out completely and cleaning back takes a little longer and lasts. Around smaller places like Nitshill, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Early resealing prevents it.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

Why us?

  • Workmanship guaranteed for 12 months
  • Constructionline member for supplier checks
  • Old sealant cut out, never sealed over
  • Colour agreed before work starts

Toilets, showers and kitchens around Nitshill

There are two care or nursing homes within about 2 miles of Nitshill. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Rooms are done a few at a time at times agreed with the home. Nitshill 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.

Schools such as Barrhead High School have toilets, changing rooms and kitchens that are best resealed in the holidays. Office washrooms on sites such as Crossmill Business Park (to the north-west of Nitshill) are in use all working day, so resealing is phased to keep some open.

Nitshill is about 1 mile east of Barrhead, in Glasgow. Anywhere in G78, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Nitshill is one of 171 places in Glasgow on our list.

How the job changes by surface

Basins and vanity tops

Basin joints get wet every time someone washes their hands, so the wall joint and bowl surrounds tend to fail before anything else. We remove the old bead and lay a fresh one of sanitary silicone.

Showers and trays

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

After the work

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

  • Note failing joints building by building
  • Report faulty extraction promptly
  • Squeegee showers and trays after busy periods
  • Inspect washroom sealant regularly

Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.

Mouldy sealant only gets harder to ignore, and complaints follow. Dealing with it while it’s just the sealant keeps it simple.

Honest limits

Honesty saves time and money. Fresh joints won’t solve:

  • Vanity carcasses that have swollen
  • A room that stays damp because ventilation isn’t working
  • Failed tanking beneath a wet-room floor or behind tiles

Not sure which it is? You can give us a call on 01277 525 020 or email us and we will tell you honestly.

Where we work in Nitshill

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

What we are called out for in Nitshill

Warmth, moisture and soap residue are exactly what mould needs, and silicone joints hold onto all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.

Typical triggers for a call:

  • Users noticing mouldy joints
  • Open joints along basins and vanity units
  • Stained sealant around pans and urinals
  • Panel joints letting water behind

For a hall at a building such as Barrhead South Parish Church, resealing the kitchen and toilets can be fitted between bookings.

How to choose a sealant contractor

Nitshill: questions and answers

Is a hospital such as Leverndale Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is a smaller place like Nitshill outside your area?

Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. Good photographs up front let us bring everything on the first visit.

Does weather matter for sealant work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Can the sealant be colour-matched?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Is old silicone taken out first?

We always remove it. New silicone won’t stick to the old so a bead over the top fails quickly.

Diagnose, treat, sign off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Travel to smaller Scottish places like Nitshill is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. Outside work also needs a suitable weather window.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. The phasing is agreed so there are always facilities open.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. You get a reopening time for every room, with signage left up until then.

What we need from you

  • Arrange parking or a loading space
  • Let us know about inductions and permits
  • Send your site hours and access windows

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or email a schedule or drawings.
