FAQs: Newchapel

Can you take on a job at a hospital such as Queen Victoria 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 every washroom in our Newchapel building shut while you work?

Normally only some of them, for a short time. We work in phases so other facilities stay open. We’ll tell you the curing time for the product before we start.

Do you work in Newchapel?

Yes. Newchapel is in our area. To discuss a job, speak to us on 01277 525 020 or email us.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, tell us and we’ll confirm them 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 many days will you need on site?

It depends on the scope, though a typical visit normally takes half a day to a day per washroom, depending on the number of fittings. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

How we handle washroom sealing in Newchapel

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, plus the kitchens and tea points that go with them. Product and method follow how hard each area is used and cleaned. We work on accessible toilets and changing rooms, IPS panels and cubicles and kitchens and tea points, and the failures we are asked to look at most are sealant laid over old silicone and now peeling and sealant stained black around basins and showers. One point of contact handles commercial sealant work in Newchapel from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Farm shops, cafés and venues in converted rural buildings around places like Newchapel have busy toilets and kitchens. We plan the work around bookings and opening times.

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

Commercial clients in Newchapel

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first.

Looking after the joints

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Mention any site permits or estates rules at quote stage
  • Keep a record of which washrooms need attention
  • Don’t leave an open joint at a basin or tray
  • Add sealant joints to planned maintenance checks

Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.

In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.

What we’re called out for in Newchapel

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They don’t stand up to constant water and they discolour and fail early.

What tends to prompt an enquiry:

  • Complaints from staff, guests or users about tired washrooms
  • Failed sealant behind washroom basins
  • Panel joints letting water behind
  • Sealant laid over old silicone and now peeling

If you manage an office at a site such as Scanda-Hus Business Park, 1.1 miles east of Newchapel, the washrooms and tea points can be done a floor at a time.

Before you book anyone

  • What level of public liability insurance do they hold?
  • The named product and why it was chosen
  • Whether their applicators hold CSCS cards
  • How they’ll work around occupants

How to choose a sealant contractor

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Hollow tiles or loose panels behind the joint
  • Failed tanking beneath a wet-room floor or behind tiles

If you’re not sure, just give us a call on 01277 525 020 or use the quote form and we’ll give you a straight answer.

Joints and surfaces we work on

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

Toilets, showers and kitchens around Newchapel

At about 23 miles from central London, Newchapel is within reach of the capital. Office washrooms on business parks see heavy weekday use, so we phase work to keep some facilities open.

Pupil toilets at schools like Imberhorne School take heavy daily use, and the holidays give the window to reseal. Clinical washrooms at sites like Queen Victoria Hospital (to the south-east of Newchapel) are scheduled with the ward so the room is out of use for as little time as possible.

Newchapel is about 3 miles north-west of East Grinstead, in Surrey. Newchapel sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.

Different surfaces, different methods

Changing rooms and gyms

Showers, floor edges and vanity units in changing rooms all need sound sealant and we look at them as one job.

Urinals and WC pans

The joint between a pan and the floor is easy to overlook. We include them in the survey.

On site: what to expect

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. Jobs in and around smaller places like Newchapel are normally planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. Joints are cleaned, degreased and dried before sealing.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Rooms reopen after the product’s cure time, and we move to the next.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Share the asbestos register for older buildings
  • Tell us which areas need to stay in use
