FAQs: Hertford Heath

Do you take on work at healthcare sites like Hertford County Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Is a smaller place like Hertford Heath outside your area?

Not at all. Hertford Heath is within our area. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

What about RAMS and site documents?

Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, with one point of contact.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Can the sealant be colour-matched?

That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Looking after the joints

Problems stay small when the joints are checked regularly. Specifically:

  • Share your site rules when you send details
  • Avoid scourers and harsh descalers on silicone
  • Clear standing water from shower floors where possible
  • Note failing joints building by building

Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.

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.

Honest limits

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Failed tanking beneath a wet-room floor or behind tiles
  • Swollen or delaminated boards behind panels or vanity tops
  • A room that stays damp because ventilation isn’t working

If you are not sure, just call the office on 01277 525 020 or email the details over and we will give you a straight answer.

What we seal

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

Different surfaces, different methods

Showers and trays

If a tray moves too much or is cracked, it needs attention first, and we will say so before resealing.

Basins and vanity tops

Basin joints get wet every time someone washes their hands, so the joint to the wall and around each bowl fails early. They are resealed with anti-mould sanitary silicone.

Commercial washrooms in Hertford Heath

There are several hotels within about 2 miles of Hertford Heath. 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. At about 20 miles from central London, Hertford Heath is within reach of the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, and resealing in phases keeps facilities available.

For an occupier at a site such as Taylor Trading Estate, 1.3 miles north of Hertford Heath, the canteen and welfare facilities need cleanable joints as much as any office. Clinical washrooms at sites like Hertford County Hospital, 2.1 miles to the north-west of Hertford Heath, are scheduled with the ward so the room is out of use for as little time as possible. For a school such as Hertford Heath Primary and Nursery School, washroom and kitchen sealant can be renewed around term dates.

Our process

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. For a building around Hertford Heath, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  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.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Warn occupants and staff about the work
  • Agree which areas must stay open

Related advice

Doing it in-house

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
