Why it’s worth doing now in Cathcart

Open or mouldy joints are hard to keep hygienic which matters most in healthcare, food and education settings. A smooth, sealed joint can be cleaned properly. Getting access arranged for a building in Cathcart takes time, so deal with all failing joints while access is up.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why clients in Cathcart choose us

Washroom sealing in Cathcart

In a commercial washroom, sealant is normally the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. Most enquiries involve sealant stained black around basins and showers and kitchen worktop joints that can’t be kept clean, across kitchens and tea points, accessible toilets and changing rooms and urinals and WCs. A single leaking joint is often how a building in Cathcart 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.

Hospitality businesses in Scotland’s cities rely on washrooms and kitchens that look right and clean easily. Washrooms get anti-mould sanitary silicone and kitchens hygienic sealant, food-safe where needed.

Work we carry out in Glasgow comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email a schedule or drawings and we will come back to it.

Do you need washroom sealing in Cathcart?

Panels and vanity units move slightly in use and trays shift slightly with each user. A bead that can’t cope with the movement splits along one edge.

Most enquiries start with something like this:

  • Washrooms that look worn because of the sealant
  • Mould spotting along silicone joints
  • Resealing that didn’t last because the old bead stayed
  • Stained sealant around pans and urinals

Hotels such as Ivory Hotel, 0.7 miles north of Cathcart, have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

Questions to ask before you book

  • Their pre-qualification and accreditations
  • The terms of the workmanship guarantee
  • How the joint faces will be prepared and primed
  • Who will actually carry out the work

How to choose a sealant contractor

Site staff or a sealant 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.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Keeping Cathcart washrooms open while we work

The west of Scotland, where Cathcart is, gets more rain than the east. Where ventilation is poor, damp washrooms here tend to see black mould in the sealant sooner. Three care or nursing homes sit less than 2 miles from Cathcart. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. We plan the work with the manager so residents are disturbed as little as possible.

For a site such as New Victoria Hospital, which lies north of Cathcart, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. Colleges such as Glasgow Clyde College - Langside Campus, 0.5 miles to the north of Cathcart, have toilets, changing rooms and catering kitchens that can be resealed around term dates.

Cathcart is about 2 miles north-east of Giffnock, in Glasgow. Our applicators travel to Cathcart for work on washrooms and wet areas. Across Glasgow, 171 places are covered, Cathcart among them.

For managing agents and facilities managers

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself normally taking half a day to a day per washroom, depending on the number of fittings. Give us the access times and building rules for your premises in Cathcart, and we’ll plan the work to suit, phased where areas need to stay in use.

  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. 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. Rooms reopen after the product’s cure time, and we move to the next.

Before we start on site

  • Share your working hours and any access restrictions
  • Confirm the product named in the specification
  • Clear stock, furniture or equipment away from the joints

Keeping the joints sound

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

  • Don’t leave trays and floors sitting wet
  • Clean sealant with gentle products and a soft cloth
  • Act on the first split you see at a shower tray
  • Note failing joints building by building

If a joint we sealed fails within 12 months, tell us and we will look at it. After that, a routine look catches failing joints early.

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

Questions about Cathcart

Would you work within a site like New Victoria Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Will you work in a care home in Cathcart without moving residents out?

Yes. We agree rooms and times with the manager and work a few areas at a time. Noise and disruption are kept to a minimum.

How long before the joints can be used?

We’ll confirm how long the chosen product needs to cure.

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

We always remove it. New silicone won’t stick to the old, so sealing over it soon peels.

How many days will you need on site?

It depends on the scope, but the work usually takes a morning or so for a small washroom, longer where showers and changing rooms are included. For bigger or phased jobs, we will set out a timescale with the quote.

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

What will the job cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.
