Washroom sealing for commercial buildings in Langton Green

Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Only replacement gets rid of it for good. Most enquiries involve failed joints along IPS and cubicle panels and complaints from staff, guests or users about tired washrooms, across showers, trays and wet room floors, urinals and WCs and vanity units and basins. Most enquiries from Langton Green start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

In a smaller place such as Langton Green, commercial washrooms tend to be in schools, pubs, cafés, surgeries, care homes and sports clubs. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.

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 spell out the cover before we begin.

Quoting for work in Langton Green

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Working within restricted access windows
  • Distance, for remote addresses
  • Backing rod, priming and other preparation
  • How much existing material needs removing

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Sending details for a quote

We can often quote from photographs and a few details. It helps to include:

  • The product your specification calls for
  • The postcode of the building
  • Whether the building will be occupied during the work
  • Clear photographs of the problem areas

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

What happens if it’s left?

Sealing on top of old silicone saves nothing. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Full removal and proper cleaning is what makes the new joint last. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What you get with us

  • Workmanship guaranteed for 12 months
  • Fixed quotes based on photos, drawings or a visit
  • Old sealant cut out, never sealed over
  • Products installed to the manufacturer’s instructions

When to call us in Langton Green

Daily commercial cleaning wears sealant faster than people expect. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges, and dirt and mould then get a foothold.

Look out for the following:

  • Sealant lifting along a tray edge
  • A new bead over an old one coming away
  • Users noticing mouldy joints
  • Discoloured joints around urinals and WC pans

Where you’re responsible for a hall attached to a building such as Church of All Saints, its kitchen and toilets need sealant that stays cleanable.

Before you book anyone

  • Their pre-qualification and accreditations
  • Can the work be phased to keep areas open?
  • Will RAMS and insurance details be available?
  • Do they follow the manufacturer’s priming guidance?

Choosing a commercial sealant contractor

From enquiry to sign-off

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If neighbouring businesses or buildings around Langton Green need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. The phasing is agreed so there are always facilities open.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. We clean and dry every surface so the new sealant can grip.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Before we start on site

  • Tell us which areas need to stay in use
  • Let us know about inductions and permits
  • Make sure the joints can be reached

Advice

Surface by surface

Kitchens and tea points

Worktop, sink and splashback joints in tea points take water and food. Sealed joints leave no gaps for food and dirt.

Changing rooms and gyms

Changing rooms in gyms and leisure centres stay wet and warm, so mould is a constant battle. We use anti-mould sanitary silicone throughout.

When to bring in a specialist

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Questions about Langton Green

Is Langton Green off your patch?

No. Places such as Langton Green are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Would you work within a site like Tunbridge Wells Nuffield Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

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 if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

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.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

How much does the work cost?

That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we’ll price it properly.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

We work a handful of rooms at a time, so the hotel keeps letting the rest. Langton Green is about 29 miles from central London. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open.

Student showers at universities like Canterbury Christ Church University - Salomons, 1.8 miles to the north-east of Langton Green, see more use than most, and their silicone shows it.
