How we handle washroom sealing in Tufnell Park

Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. We work on IPS panels and cubicles, vanity units and basins and urinals and WCs, and the failures we are asked to look at most are washrooms that look worn because of the sealant and black mould inside silicone joints that cleaning can’t shift. Whoever orders the work in Tufnell Park, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In a London area such as Tufnell Park, commercial washrooms in offices, hotels and leisure buildings see constant use. We cut out tired sealant around vanity units, cubicles, IPS panels and showers and lay fresh anti-mould sanitary silicone, a block of facilities at a time.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

How a job runs

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a job in Tufnell Park, access comes first. Send the building rules and access times with your enquiry.

  1. First, the phasing is agreed so facilities stay open.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

Getting the site ready

  • Flag any permit to work we’ll need
  • Share your working hours and any access restrictions
  • Warn occupants and staff about the work

Advice

Aftercare for building managers

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Share your site rules when you send details
  • Keep extract fans working and vents clear
  • Leave signs up until the cure time is over
  • Keep a record of which washrooms need attention

Each room goes back into use only when the sealant has cured enough. We will tell you when the wet areas can be used and signage stays in place until that time.

Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.

For managing agents and facilities managers

CHAS accredited and a Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Honest limits

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • A room that stays damp because ventilation isn’t working
  • Leaks through tanking or membranes below the finishes
  • Hollow tiles or loose panels behind the joint

If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think.

What we seal

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

FAQs: Tufnell Park

Can you take on a job at a hospital such as The Whittington Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Must a hotel around Tufnell Park close while you work?

Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Does weather matter for sealant work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

What will the job cost?

We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

How many days will you need on site?

It depends on the scope, but the work normally takes a few hours for one toilet block, with bigger buildings phased across a number of visits. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Common problems we fix in Tufnell Park

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting and they discolour and fail early.

What tends to prompt an enquiry:

  • Panel joints letting water behind
  • Users noticing mouldy joints
  • Stained or open joints at kitchen sinks and worktops
  • Stained sealant around pans and urinals

At a college such as Working Men’s College, 0.5 miles south of Tufnell Park, washroom and kitchen sealant is best renewed in the holidays or in phases during term.

How to choose a sealant contractor

Busy facilities in and around Tufnell Park

A London building with hundreds of occupants can’t lose every washroom for a day, so resealing goes floor by floor, agreed with the facilities team. There are a good number of hotels within about 2 miles of Tufnell Park. 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.

For centre management at a site such as Arena Shopping Park, 2.1 miles north-east of Tufnell Park, washroom work is planned around footfall. Units at estates like Bush Industrial Estate (to the north of Tufnell Park) have welfare blocks whose showers and toilets see shift after shift.

Why it’s worth doing now in Tufnell Park

Leaving the job until a shutdown often means living with it for months. Phasing lets it happen now, with facilities kept in use. Getting scaffold, permits or access booked in Tufnell Park takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
