Halls and community buildings near places like Haultwick 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.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the job changes by surface

Wet-room floors and floor-to-wall joints

We seal the visible joints; we don’t install or repair waterproofing below, and we will say if the trouble looks to be beneath the floor.

Kitchens and tea points

Kitchen joints need to be smooth and sealed so they can be cleaned properly. Where food contact is possible, we use a hygienic, food-safe sealant.

From enquiry to sign-off

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. For a building around Haultwick, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. Every room is surveyed and the failed joints listed.
  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. Each area is handed back when ready.

Getting the site ready

  • Have the specification and drawings to hand
  • Tell us which areas need to stay in use
  • Move anything stored against the joints

Advice

Common problems we fix in Haultwick

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting and they discolour and fail early.

It’s worth sending us details if you spot any of the following:

  • Failed joints along IPS and cubicle panels
  • Split or peeling sealant at shower trays
  • Discoloured joints around urinals and WC pans
  • Failed sealant in a tea point or staff kitchen

At a school such as Munden Church of England Voluntary Controlled Primary School, changing rooms and kitchens need cleanable joints as much as the toilets.

Questions to ask before you book

  • Can the work be phased to keep areas open?
  • Will CSCS-carded applicators be on site?
  • Do they follow the manufacturer’s priming guidance?
  • Is the sealant right for the movement and the substrate?

Questions to ask before you appoint anyone

Why deal with it now?

Waiting for a holiday closure can leave failing joints in place for a long time. Phasing lets it happen now, with facilities kept in use. Older rural buildings around Haultwick move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

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 rules also count.

Common questions from Haultwick clients

Is Haultwick too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do we have to close all our washrooms in Haultwick for resealing?

Normally only some of them, for a short time. We work in phases so other facilities stay open. Each area is handed back once the sealant has cured enough to use.

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

How long does a typical visit take?

That varies with the scale of the job, though a typical visit normally takes a morning or so for a small washroom, longer where showers and changing rooms are included. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

What do you charge?

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

What about RAMS and site documents?

Each site asks for different documents, so tell us what you need and we will confirm it when we quote.

Sanitary sealant for Haultwick buildings

Haultwick lies roughly 27 miles out from central London, in a commuter belt where offices and business parks are common. Office washrooms on business parks see heavy weekday use, so we work a block of facilities at a time.

Where you’re responsible for a hall attached to a building such as Parish Church of All Saints, its kitchen and toilets need sealant that stays cleanable. Hotels such as Green End Park Hotel (0.7 miles south-west of Haultwick) have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

What sealant work can’t fix

Being straight saves everyone time. New sealant won’t cure:

  • Loose panels, vanity units or tiles, which need fixing first
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Water escaping beneath the floor rather than through a joint

If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think.

Surfaces we seal

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

Keeping the joints sound

For the best life from the joints:

  • Photograph and log failed joints across the estate
  • Clean sealant with gentle products and a soft cloth
  • Leave signs up until the cure time is over
  • Inspect washroom sealant regularly

Where possible, have shower floors and trays squeegeed after busy periods. Standing water on a joint all day shortens its life.

Mouldy sealant only gets harder to ignore and users notice. Dealing with it while it’s just the sealant keeps it simple.
