Washroom sealing across Farringdon

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

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
  • Photograph and log failed joints across the estate
  • Clean sealant with gentle products and a soft cloth
  • Don’t leave an open joint at a basin or tray

Keep extract fans working and vents clear. Constant damp lets mould take hold even on anti-mould grades, so get faulty extract looked at.

A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme and more closures to manage.

About our washroom sealing in Farringdon

Whether it’s a single toilet block in Farringdon or a programme across several buildings, we work the same way: send details, get a fixed quote, we seal, guaranteed. A few photographs and a count of fittings are enough for a quick quote, or we can arrange a visit. The enquiries we see most involve split or peeling sealant at shower trays and kitchen worktop joints that can’t be kept clean, on vanity units and basins, IPS panels and cubicles and kitchens and tea points. A single leaking joint is often how a building in Farringdon 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.

Farm shops, cafés and venues in converted rural buildings around places like Farringdon have busy toilets and kitchens. Tell us your opening times and quiet periods and we’ll plan around them.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Doing it in-house

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Signs you need washroom sealing in Farringdon

Daily commercial cleaning wears sealant faster than people expect. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead, and dirt and mould then get a foothold.

It’s worth sending us details if you spot any of the following:

  • Sealant laid over old silicone and now peeling
  • Urinal joints that look unhygienic
  • Shower tray joints that have opened up
  • Gaps where vanity tops meet the wall

Church halls and community buildings, such as those at Church of All Saints, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

What your quote should include

  • Their pre-qualification and accreditations
  • What level of public liability insurance do they hold?
  • How the joint faces will be prepared and primed
  • How long is the guarantee, and what does it include?

Healthcare washrooms on sites such as Alton Community Hospital, 2 miles to the north of Farringdon, are resealed area by area, under the site’s own infection-control rules.

What happens if it’s left?

Leaving the job until a shutdown often means living with it for months. With phasing, the work can go ahead while most facilities stay open. Halls, stores and units around places like Farringdon may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

What you get with us

  • Products installed to the manufacturer’s instructions
  • Failed material removed, not covered up
  • One phone line for London, the South East and Scotland
  • Matching to RAL references, product permitting

Advice

Farringdon: questions and answers

Do we have to close all our washrooms in Farringdon for resealing?

Usually 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 hospital work, at somewhere like Alton Community Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

How long does a typical visit take?

It depends on the scope, but the work typically takes between a morning and a week or so, set by the number of rooms and the phasing you need. For bigger or phased jobs, we will set out a timescale with the quote.

Is it possible to just clean mouldy silicone?

Not for long. The mould is inside the silicone so cleaning only lightens it for a while. Replacement is the lasting fix.

How do we ask for a quote?

You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or email drawings and photos. Include photos or drawings if you have them.

How long before the toilets can reopen?

That varies with the sealant and the room temperature. You will get a reopening time for each area, and signs stay up until then.

Do you work in hospitals, clinics and care homes?

Yes, healthcare and care settings are part of our work. Tell us what records you need and we will confirm with the quote.

How the quote is worked out

We price every job individually. The things that drive the figure:

  • How much there is to seal
  • Removal of failed or old sealant
  • The product specified
  • Access and working height

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Sending details for a quote

A few photographs plus some basic facts will normally do. It helps to include:

  • Specification clauses that apply
  • The postcode of the building
  • Photos of the joints, close up and from further back
  • Any dates the work must fit around

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or ring 01277 525 020 or email the details over to discuss it first.
