Washroom sealing in St Pancras

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. Product and method follow how hard each area is used and cleaned. We work on kitchens and tea points, IPS panels and cubicles and urinals and WCs, and the usual reasons a site gets in touch are open joints at the base of cubicle panels and users noticing mouldy joints. A single leaking joint is often how a building in St Pancras first comes to us: we look at the rest while we are there and tell you what we find.

In St Pancras, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Different surfaces, different methods

IPS and cubicle panels

Panels flex slightly in use so the bead needs to cope with it. We check fixings before sealing.

Showers and trays

A tray that rocks or has cracked won’t be fixed by sealant, and we’ll say so before resealing.

Cost factors for washrooms and wet areas

The price varies from site to site. Expect it to depend on:

  • Whether the work must be split into stages
  • Travel to remote or island sites
  • Whether old sealant has to be cut out first
  • Any access equipment needed

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • The product your specification calls for
  • When you need the work done
  • Whether the building will be occupied during the work
  • Access details, including height

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. For a chat about it beforehand, phone 01277 525 020 or use the quote form.

Wet areas in St Pancras’s workplaces

Busy London buildings need some toilets open at all times, so we take one block of facilities out of use at a time. Plenty of hotels sit less than 2 miles from St Pancras. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. Rooms are done in turn so most stay available.

For a campus such as University of the Arts London (under half a mile south of St Pancras), showers in residences and washrooms in teaching blocks can be programmed around term dates. Welfare facilities in units on estates such as Roman Way Industrial Estate, 1.2 miles to the north of St Pancras, have showers, toilets and kitchens with sealant that works hard.

St Pancras is about 2 miles north-west of London, in Greater London. St Pancras sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. St Pancras is one of 764 places in Greater London on our list for washrooms and wet areas.

We cover the NW1W, W1T and N1 postcode districts. We cover commercial and managed buildings on Shoe Lane, Long Lane and City Road and the roads nearby. You will find St Pancras on or near the A4 and A40. Nearby places we also cover include Bloomsbury (1 mile south-west), Kings Cross (1 mile north-west), Holborn (1 mile south-east), Clerkenwell (1 mile east) and Angel (1 mile north-east) for washrooms and wet areas. Nearby towns on our patch include Kensington (4 miles south-west), Walthamstow (6 miles north-east), Hampstead (3 miles north-west), Ruislip (13 miles west), Brompton (3 miles south-west) and Stockwell (4 miles south). St Pancras is one of the busier places in Greater London, and we take on washrooms and wet areas for its commercial and public buildings.

Local landmarks in St Pancras

In St Pancras, that means premises near Lincoln's Inn Fields, City Academy and Elizabeth Garrett Anderson School.

The closest station to St Pancras is London Kings Cross station, roughly 0.5 miles north-west. Nearby you will also find Montfichet's Tower (1.1 miles south-east) and Royal National Throat (less than half a mile north). Green spaces nearby include Barnsbury Wood and Ludgate Hill.

Signs you need washroom sealing in St Pancras

Much of the failed sealant we remove was applied over old silicone or residue. New silicone won’t grip the old, so it soon lets go.

If one of these sounds familiar, it’s time for a closer look:

  • Urinal joints that look unhygienic
  • Mould spotting along silicone joints
  • Failed joints along IPS and cubicle panels
  • Complaints from staff, guests or users about tired washrooms

Toilets at places like Brunswick Centre (less than half a mile south-west of St Pancras) are cleaned constantly, so silicone needs to be sound and smooth.

Questions to ask before you appoint anyone

Building owners, agents and FMs in St Pancras

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in St Pancras can sit alongside others in a wider programme.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

On site: what to expect

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Planning a London job such as one in St Pancras starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.

  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. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

What we need from you

  • Explain the parking and delivery arrangements
  • Tell us which areas need to stay in use
  • Tell staff and tenants when we will be in

Request a quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Maintenance after handover

For the best life from the joints:

  • Mention any site permits or estates rules at quote stage
  • Add sealant joints to planned maintenance checks
  • Brief cleaning staff to treat joints gently
  • Respect the cure time before reopening each room

Ventilation is half the battle. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.

Small numbers of failed joints are quick to phase in. Left, it tends to become a building-wide job and more closures to manage.

Questions we’re asked in St Pancras

Will you plan work around the academic year at somewhere like University of the Arts London?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Would you work within a site like Great Ormond Street Hospital for Children?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you work in St Pancras?

Yes. We take on work across St Pancras, with one number for every area we cover.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Do you phase washroom resealing?

The work is phased so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time. Tell us your site hours and access windows and we’ll plan around them.

How long does a typical visit take?

That varies with the scale of the job, but the work usually 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 will give you a timescale with the quote.
