Washroom sealing for Four Elms sites

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

What we’re called out for in Four Elms

Much of the failed sealant we remove was applied over old silicone or residue. Silicone won’t adhere to a silicone bead, so it soon lets go.

These are often picked up first by site or facilities staff:

  • Users noticing mouldy joints
  • Black mould inside silicone joints that cleaning can’t shift
  • Failed sealant in a tea point or staff kitchen
  • Gaps where vanity tops meet the wall

Hotels such as Hever Hotel, 1.5 miles south-east of Four Elms, have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

Questions to ask before you book

  • Will CSCS-carded applicators be on site?
  • How they handle RAMS and site documents
  • Is the sealant right for the movement and the substrate?
  • Health and safety accreditation such as CHAS

Questions to ask before you appoint anyone

Washroom sealing in Four Elms, done properly

Accessible WCs, showers and changing areas have their own pinch points: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. Gaps in those places let water get under the floor or behind panels, so we look at them closely. We work on accessible toilets and changing rooms, urinals and WCs and IPS panels and cubicles, and what we’re called in for most is stained sealant around pans and urinals and split or peeling sealant at shower trays. Looking for mastic applicators who cover Four Elms? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Halls and community buildings near places like Four Elms are used by different groups through the week, and their toilets and kitchens show it. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits, and we clear our waste as we work. For work around Four Elms, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  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. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Rooms reopen after the cure time.

Before we start on site

  • Arrange parking or a loading space
  • Confirm the product named in the specification
  • For older buildings, check the asbestos register before work

Commercial clients in Four Elms

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

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Looking after the joints

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Act on the first split you see at a shower tray
  • Keep a record of which washrooms need attention
  • Brief cleaning staff to treat joints gently
  • Add sealant joints to planned maintenance checks

Add washroom sealant to routine inspections. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and photograph anything new.

A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.

Keeping Four Elms washrooms open while we work

A 2-mile radius around Four Elms takes in a number of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. Rooms are done in turn so most stay available. Four Elms is about 21 miles from central London. Business park offices have washrooms in daily use by staff, which is why the work is phased.

At a school such as Four Elms Primary School, changing rooms and kitchens need cleanable joints as much as the toilets. Where you are responsible for a hall attached to a building such as Congregational Church, its kitchen and toilets need sealant that stays cleanable.

What the job involves on each surface

Wet-room floors and floor-to-wall joints

Wet-room floors and the joints where flooring turns up the wall need to stay sound. We reseal the floor-to-wall junctions and around drains where sealant is used.

IPS and cubicle panels

Cubicle and IPS panels move when leaned on or knocked, so the sealant has to take that movement. Loose panels are flagged before any sealant goes on.

Four Elms: questions and answers

Does a hotel in Four Elms need to shut while its sealant is renewed?

Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.

Is a hospital such as Edenbridge and District War Memorial Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

What sealant do you use in washrooms?

Sanitary silicone with anti-mould additives for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

How many days will you need on site?

It depends on the scope, though a typical visit usually 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’ll set out a timescale with the quote.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Do you need to remove the old sealant?

We strip every bit of the failed bead and wipe away the residue first. It’s the difference between a joint that lasts and one that peels.

Quoting for work in Four Elms

These are the things that shape the price:

  • How much existing material needs removing
  • Any access equipment needed
  • Working within restricted access windows
  • The total length or number of joints

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Sending details for a quote

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

  • Drawings or a marked-up plan, if available
  • Whether an asbestos survey exists
  • Whether the building will be occupied during the work
  • Where the site is, with the postcode

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
